Molex 43640-0200 is published on this site as a Micro-Fit 3.0 connector housing record. The page identifies a single-row, two-circuit plug housing with panel-mount ears and calls it a wire-to-wire product. That visible catalogue identity is a useful starting point for a panel or harness enquiry. It does not by itself approve a mating set, panel design, assembly sequence, retention result, wire selection, or application outcome. This guide keeps a review focused on the exact record and the evidence that is still needed.
1. Capture the exact Micro-Fit 3.0 record
Start with the published Molex 43640-0200 product page. Record the full part number, manufacturer name, page URL, request date, and the description visible when it was checked. The current listing identifies the item as a Micro-Fit 3.0 plug housing, single row, two circuits, with panel-mount ears. This creates a traceable identity record before an abbreviated purchase description or an unlabeled image begins to drive the discussion.
Keep that catalogue identity separate from approval evidence. A product page cannot establish the exact mating component, panel cutout, harness drawing, terminal choice, tooling, assembly method, inspection criterion, or result required for a particular build. Those conclusions need the governing documents for the configuration being reviewed.
2. Define the panel-mount question first
“Need a two-circuit housing” is not a complete decision. Clarify whether the request is for record lookup, a quotation, a prototype review, a released production task, a service investigation, or an engineering change. Capture the equipment or panel reference, harness designation, drawing revision, owner, decision deadline, and the evidence expected from the review.
For example, a sourcing question may require the exact number and commercial requirements. A panel-integration or production decision may require controlled mechanical data, an approved bill of materials, a released drawing, work instruction, and inspection criteria. Do not fill missing requirements with assumptions about fit, mounting, mating, current capability, temperature, sealing, or compatibility.
3. Keep other Molex listings as independent records
The site also publishes Molex 43045-0601 as a PCB header and receptacle record, plus Molex 39-30-3045 as another separate catalogue entry. These links help a reviewer preserve the identity of multiple numbers in one enquiry. A shared brand, series wording, connector category, or nearby page does not prove a mating relationship, fit, substitution, or approved use with 43640-0200.
Give every part number its own line in the review log. Retain its source, visible listing description, document reference, and unresolved questions. When an interface relationship matters, request documentation that explicitly connects the exact parts and actual configuration.
4. Build a concise evidence checklist
A dependable review separates confirmed page facts from decisions that still need authorization. Preserve the product link and identity, then add the controlled panel or harness reference, revision context, and the person responsible for approval. Quantity, packaging, delivery, and commercial needs should remain separate from technical acceptance. A web listing does not promise current stock, price, lead time, or future availability.
- Exact Molex 43640-0200 number and the source that supplied it.
- Published Micro-Fit 3.0 connector-housing page link and check date.
- Panel, harness, drawing, equipment, or service reference with revision context.
- The decision required: record lookup, sourcing review, controlled build, or engineering disposition.
- Current approved bill of materials, drawing, work instruction, and inspection requirements.
- Open questions about interface, panel mounting, terminals, process, or application performance.
Frequently asked questions
Does the 43640-0200 page prove a panel installation?
No. It identifies the published catalogue record, including its panel-mount wording. Installation and acceptance must follow the controlled information applicable to the exact equipment or harness task.
Does another Molex product page prove mating or fit?
No. Common branding or related connector language is not evidence of mating, fit, retention, replacement, tooling, sealing, performance, or compatibility. Confirm any relationship from the governing documentation for the exact configuration.
What should a technical or sourcing request include?
Provide the full part number, product-page link, source record, panel or harness reference, revision context, quantity requirement, decision needed, and documents already available. This gives a reviewer a defensible starting point while making unverified gaps visible.
Conclusion
Molex 43640-0200 provides a clear Micro-Fit 3.0 connector-housing identity for a disciplined panel-mount review. Begin with the exact published record, define the real question, collect controlled evidence, and keep other listings independent until documentation proves a relationship.
