Summary. EPPTC lists Molex 502351-0900 as a DuraClik wire-to-board receptacle housing with one row and nine circuits. Molex’s current product record, 502351 series chart and DuraClik data sheet are useful source anchors for identifying the part and the surrounding connector family. They are not a production release. This checklist shows how to keep the part identity, terminal research, header research and project evidence separate, so an enquiry does not turn family-level information into an unverified fit, process or replacement claim.
Start with the complete ordering identity
Open the EPPTC 502351-0900 product record as a local catalogue starting point, then retain the complete suffix in the BOM, sample label, request and source log. The Molex official 5023510900 product page and the Molex 502351 series chart identify the manufacturer’s public part-family record. The series chart includes 5023510900 as a natural, single-row nine-circuit housing; record the current page, access date and any linked document revision instead of copying an abbreviated family name into a project note.
A part number that differs only by color, circuit count, termination or suffix is a different research target. Treat it as a new evidence row, not as a variation that can be inferred from appearance. The connector housings category is useful for finding catalogue records, but it does not establish that two housings are interchangeable.
Use DuraClik family material as a map, not a release
The Molex DuraClik 2.00 mm wire-to-board data sheet presents the Standard family with 502351 housings, related terminal series and header families. It provides a legitimate navigation map for further review. It does not select the exact terminal part, wire construction, crimp tooling, plating, header suffix, board layout, inspection method or finished-product suitability for a particular project.
Keep each proposed component in its own row: housing, terminal, header, retainer where applicable, wire, and any accessory. Capture the full manufacturer number, document title, revision, source URL and access date. If the source is family-level, mark it as family-level. A useful evidence log makes uncertainty visible instead of filling it with presumed mating relationships.
Separate interface research from crimp-process decisions
DuraClik material can help identify terminal series worth researching. That is not the same as authorizing a crimp. The production decision needs the exact terminal record, applicable manufacturer documentation, the selected wire construction and size, insulation diameter, tooling, process limits and inspection criteria. Do not derive crimp geometry, pull-force acceptance, insertion force or tool choice from a housing description or from this article.
Ask for the controlled documents that correspond to the precise proposed terminal and build. Record whether every cited document applies to the intended part number and revision. If a terminal, header or process document cannot be tied to the exact configuration, keep the item open for review rather than presenting the DuraClik name as confirmation.
Review a wire-to-board proposal in layers
The DuraClik Connector System page groups independent catalogue records on EPPTC. Use it to navigate, then return to the manufacturer’s own part and document references for the interface under consideration. The same discipline applies when context involves the automotive application catalogue: an application label supports discovery, not a claim that a part is approved for a vehicle, environment or safety function.
- Freeze 502351-0900 exactly, including its suffix and the revision of each reviewed source.
- Identify every proposed terminal and header by its own complete manufacturer part number.
- Record the intended circuit count, wire data, board context and environmental requirements outside the catalogue description.
- Request current manufacturer drawings, terminal application information and assembly or inspection requirements as applicable.
- Separate a verified source link from an open technical question in the same evidence log.
- Keep quantity, packaging, availability, lead time and price in a distinct commercial review.
FAQ
Does 502351-0900 alone define a complete DuraClik connection?
No. It identifies a housing record. A complete connection requires evidence for the exact terminal, header, wire, board interface, process and verification criteria proposed for the project.
Can a family data sheet select a crimp tool?
No. It can guide research to the relevant product family. Tooling and crimp acceptance must come from current documentation for the exact terminal, wire and process.
Does an automotive label establish application approval?
No. It is navigation context only. Project suitability, testing and approvals remain separate responsibilities supported by controlled requirements.
Conclusion
For Molex 502351-0900, preserve the full part identity, distinguish family material from exact-part evidence and turn every interface or process assumption into a named question. This approach makes catalogue research more useful without turning it into compatibility, manufacturing or application approval.
