Key Parameters

Substitute Part Grouping Explanation

Substitution of the 91618-310 is determined by strict equivalence across the following critical parameters:

• Connector geometry: 20-position receptacle with 0.100" (2.54mm) pitch and 2-row configuration
• Electrical interface: Female socket contacts with gold mating finish
• Mechanical interface: Surface mount termination with push-pull fastening and board lock
• Material compliance: UL94 V-0 flammability rating and thermoplastic glass-filled insulation
• Series compatibility: Dubox™ series designation

The substitute part 91618-310LF maintains identical electrical and mechanical specifications while differing in product status and regulatory compliance. The "LF" suffix indicates lead-free compliance, representing the primary distinction between the original and substitute part.

Parameter Comparison

Engineering Selection Recommendations

The 91618-310LF serves as the direct active equivalent to the obsolete 91618-310. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, pitch spacing, and material properties.

The primary distinction is regulatory compliance: the 91618-310LF is RoHS compliant, while the original 91618-310 is RoHS non-compliant. For new designs and applications subject to RoHS requirements, the 91618-310LF is the appropriate selection. Both parts carry UL94 V-0 flammability certification and unlimited moisture sensitivity rating (MSL 1), suitable for automotive, industrial, telecommunications, and general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the 91618-310LF be used as a direct replacement for the 91618-310?

A: Yes. The 91618-310LF is electrically and mechanically equivalent to the 91618-310. Both parts feature identical 20-position receptacle configuration, 0.100" (2.54mm) pitch spacing, gold-plated mating contacts, and push-pull fastening. The primary difference is RoHS compliance status and product availability (active vs. obsolete).

Q: What does the "LF" suffix indicate?

A: The "LF" suffix denotes lead-free compliance. The 91618-310LF meets RoHS requirements, whereas the original 91618-310 does not.

Q: Are there packaging differences between these parts?
