Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 91615-312 is determined by strict equivalence across the following critical parameters:

• Connector geometry and pitch: 24-position, 0.100" (2.54mm) mating pitch, 2-row configuration with 0.100" row spacing
• Contact system: Female socket contacts with gold mating finish (30.0µin thickness) and tin post finish (78.7µin thickness)
• Mounting and termination: Surface mount with solder termination
• Mechanical interface: Push-pull fastening with board lock feature
• Physical envelope: 10.81mm mated stacking height, 0.275" (6.99mm) insulation height
• Material and safety: Thermoplastic glass-filled insulation, UL94 V-0 flammability rating

The substitute part 91615-312LF maintains complete equivalence across all these parameters. The primary difference is product status and regulatory compliance, not functional or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 91615-312LF is the direct functional equivalent of the 91615-312. Both parts are electrically and mechanically identical across all specified parameters. Selection between these parts should be based on the following factors:

For new designs and active production: The 91615-312LF is the appropriate choice. It maintains active product status with Amphenol ICC, ensuring ongoing availability and supply chain stability. The part is RoHS compliant and REACH affected, meeting current regulatory requirements for most applications in automotive, industrial, telecommunications, and general purpose markets.

For legacy system maintenance: The 91615-312 remains functionally compatible with existing assemblies. However, due to obsolete status, sourcing may be limited. The 91615-312LF provides identical performance and can be substituted directly in repair and maintenance scenarios.

Compliance considerations: The 91615-312LF's RoHS compliance and REACH affected status align with modern regulatory frameworks. Organizations subject to RoHS or REACH requirements should prioritize the 91615-312LF for new applications.

Frequently Asked Questions (FAQ)

Q: Are the 91615-312 and 91615-312LF mechanically interchangeable?

A: Yes. Both parts share identical connector geometry, pitch spacing (0.100"), number of positions (24), mounting type (surface mount), and mated stacking height (10.81mm). They are direct mechanical substitutes with no PCB layout or assembly modifications required.

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

A: The primary differences are product status and regulatory compliance. The 91615-312 is obsolete and RoHS non-compliant, while the 91615-312LF is active and RoHS compliant. All electrical and mechanical specifications are identical.

Q: Can I use the 91615-312LF as a drop-in replacement for the 91615-312?

A: Yes. The 91615-312LF is a direct functional and mechanical equivalent. No design changes, PCB modifications, or assembly procedure adjustments are necessary.

Q: What does the "LF" suffix in 91615-312LF indicate?

A: The "LF" designation indicates lead-free construction, which is associated with RoHS compliance. This part meets RoHS requirements for restricted substance limitations.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical contact materials (phosphor bronze), contact finishes (gold mating, tin post), and physical dimensions. Electrical performance is equivalent.

Q: What packaging is available for the 91615-312LF?

A: The 91615-312LF is supplied in tube packaging. The original 91615-312 packaging specification was not provided in the technical data.

Q: Which part should I specify for new designs?

A: Specify the 91615-312LF for new designs. It is the active product with current regulatory compliance and assured supply chain availability.
