Key Parameters

Substitute Part Grouping Explanation

The 76785-401 has one direct substitute within the Duflex™ series: the 76785-401LF. Substitution eligibility is determined by the following critical parameters that must remain constant:

• Base Product Number: Both parts share the base number 76785, ensuring identical contact geometry and electrical specifications
• Series: Both belong to the Duflex™ series, maintaining mechanical compatibility
• Pin or Socket Configuration: Both are socket contacts
• Contact Termination Method: Both use crimp termination
• Contact Finish Material: Both feature tin finish
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• ECCN and HTSUS Classification: Identical regulatory classifications

The primary difference between these parts is packaging format (Bulk versus Cut Tape) and compliance status. The 76785-401LF variant is RoHS Compliant and REACH Affected, whereas the 76785-401 is RoHS non-compliant. The 76785-401LF also specifies contact finish thickness at 196.9µin (5.00µm).

Parameter Comparison

Engineering Selection Recommendations

Both the 76785-401 and 76785-401LF are active production parts suitable for FFC/FPC connector applications within the Duflex™ series. Selection between these parts should be based on compliance requirements and packaging needs:

76785-401 is appropriate for applications where RoHS non-compliance is acceptable and bulk packaging is preferred for high-volume manufacturing operations.

76785-401LF is the required choice for applications subject to RoHS Directive compliance or REACH regulations. The "LF" designation indicates lead-free compliance. This variant is supplied in Cut Tape packaging, which is standard for automated assembly processes and component traceability requirements.

Both parts maintain identical electrical and mechanical specifications within the Duflex™ series, ensuring functional interchangeability when compliance and packaging requirements are met.

Frequently Asked Questions (FAQ)

Q: Are the 76785-401 and 76785-401LF electrically and mechanically interchangeable?

A: Yes. Both parts share the same base product number (76785), series designation (Duflex™), socket configuration, crimp termination method, and tin contact finish. They are functionally equivalent for electrical and mechanical purposes.

Q: What does the "LF" suffix in 76785-401LF indicate?

A: The "LF" suffix designates lead-free compliance, indicating the part meets RoHS Directive requirements. The 76785-401 without this suffix is RoHS non-compliant.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies loose components in quantity, suitable for manual assembly or high-volume bin storage. Cut Tape (CT) packaging provides components on carrier tape in precise quantities, optimized for automated pick-and-place assembly equipment and component tracking.

Q: Which part should I select for a new design?

A: Selection depends on regulatory requirements. If RoHS compliance is mandatory, use 76785-401LF. If your application or market does not require RoHS compliance, either part is acceptable based on packaging preference.

Q: Are there any differences in contact finish thickness between these parts?

A: The 76785-401LF specifies contact finish thickness at 196.9µin (5.00µm). The 76785-401 does not provide this specification. Both use tin finish material.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
