Key Parameters

Substitute Part Grouping Explanation

Substitution of the 91618-316 is determined by strict equivalence across the following critical parameters:

• Connector geometry: 32 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
• Electrical interface: Female socket contacts with gold mating finish
• Mechanical interface: Surface mount termination with push-pull fastening and board lock
• Physical envelope: 0.275" (6.99mm) insulation height, 10.81mm mated stacking height
• Material compliance: UL94 V-0 flammability rating, thermoplastic glass-filled insulation

The 91618-316LF meets all these criteria as a direct substitute. The primary distinction is product status and regulatory compliance, not functional or mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The 91618-316LF is the direct functional equivalent of the 91618-316. All mechanical, electrical, and dimensional parameters are identical. Selection between these parts is determined by regulatory and availability factors:

Use 91618-316LF for new designs and ongoing procurement due to active product status and RoHS compliance. The part is currently in stock and maintains full compatibility with existing board designs using the 91618-316.

The 91618-316 remains suitable for legacy system maintenance where RoHS compliance is not a requirement and existing inventory is available. Both parts share identical connector geometry, contact configuration, and mating characteristics.

The transition from 91618-316 to 91618-316LF involves no design changes, PCB layout modifications, or mating connector updates.

Frequently Asked Questions (FAQ)

Q: Are the 91618-316 and 91618-316LF mechanically interchangeable?

A: Yes. Both connectors have identical pitch spacing (0.100"), position count (32), row configuration (2 rows), mounting type (surface mount), and mated stacking height (10.81mm). They mate with the same plug connectors without modification.

Q: What is the difference between these two part numbers?

A: The 91618-316LF is the active production equivalent with RoHS compliance and REACH affected status. The 91618-316 is obsolete and RoHS non-compliant. All functional and dimensional specifications are identical.

Q: Can I use 91618-316LF as a direct replacement in existing assemblies?

A: Yes. The 91618-316LF is a direct substitute with no design or assembly process changes required. It is pin-compatible and dimensionally equivalent.

Q: What packaging is available for the 91618-316LF?

A: The 91618-316LF is supplied in tube packaging. The original 91618-316 packaging specification is not provided in the technical data.

Q: Are there any compliance differences I should consider?

A: The 91618-316LF is RoHS compliant and REACH affected, while the 91618-316 is RoHS non-compliant and REACH unaffected. For applications subject to RoHS or REACH regulations, the 91618-316LF is the required choice.

Q: What is the moisture sensitivity level for these connectors?

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