Substitute Part Grouping Explanation

Substitution eligibility for the 91618-307B is determined by strict equivalence across the following critical parameters:

Connector geometry: 14-position receptacle configuration with 2-row layout
Pitch specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting technology: Surface mount termination with solder connection
Contact system: Female socket contacts with gold mating finish
Mechanical interface: Push-pull fastening with board lock features
Physical envelope: Insulation height of 0.275" (6.99mm) and mated stacking height of 10.81mm
Material compliance: UL94 V-0 flammability rating and thermoplastic glass-filled insulation

The substitute part 91618-307BLF maintains identical electrical and mechanical specifications across all these parameters, with the primary distinction being product status and regulatory compliance posture.

Engineering Selection Recommendations

The 91618-307BLF is a direct functional equivalent to the 91618-307B across all electrical and mechanical parameters. Selection between these parts should be based on the following criteria:

For new designs or systems requiring regulatory compliance: The 91618-307BLF is the appropriate choice, as it carries active product status and RoHS compliance certification. This part is suitable for applications subject to environmental and hazardous substance regulations.

For legacy system support or replacement: The 91618-307B remains electrically and mechanically compatible with existing assemblies. However, given its obsolete status, procurement may be limited. The 91618-307BLF provides a compliant alternative with identical form, fit, and function.

Regulatory considerations: The 91618-307BLF's RoHS compliance and REACH-affected status indicate it meets current environmental directives. The 91618-307B's REACH-unaffected status reflects its legacy classification. Both parts share identical UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels.

Frequently Asked Questions (FAQ)

Q: Are the 91618-307B and 91618-307BLF mechanically interchangeable?

A: Yes. Both parts share identical connector geometry, pitch spacing (0.100"), row configuration (2 rows), mounting type (surface mount), and physical envelope dimensions (10.81mm mated stacking height). They are direct mechanical substitutes.

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

A: The primary differences are product status and regulatory compliance. The 91618-307B is obsolete and RoHS non-compliant, while the 91618-307BLF is active and RoHS compliant. All electrical and mechanical specifications are identical.

Q: Can I use the 91618-307BLF as a replacement in existing designs using the 91618-307B?

A: Yes. The 91618-307BLF is a direct substitute with no design changes required. It maintains the same contact configuration, pitch, fastening mechanism, and physical dimensions.

Q: Does packaging differ between these parts?

A: Yes. The 91618-307B packaging is not specified in available documentation, while the 91618-307BLF is supplied in tube packaging. Confirm packaging requirements with your procurement specifications.

Q: Are there any contact finish or material differences?

A: No. Both parts feature identical gold mating contact finish (30.0µin / 0.76µm), tin post finish (78.7µin / 2.00µm), phosphor bronze contact material, and thermoplastic glass-filled insulation.

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

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