Engineering Selection Recommendations

The 91615-323LF serves as the direct substitute for the obsolete 91615-323. Both parts are functionally and mechanically identical across all electrical and physical parameters. The primary distinctions are:

Product Status: The 91615-323LF is active production, whereas the 91615-323 is obsolete. For new designs or ongoing procurement, the 91615-323LF is the appropriate selection.

Regulatory Compliance: The 91615-323LF is RoHS compliant and REACH affected, reflecting current environmental regulations. The 91615-323 is RoHS non-compliant and REACH unaffected, indicating its legacy status.

Packaging: The 91615-323LF is supplied in tube packaging, providing standardized handling and storage for production environments.

Selection of the 91615-323LF eliminates obsolescence risk and aligns with current regulatory requirements while maintaining full electrical and mechanical compatibility with existing board designs.

Frequently Asked Questions (FAQ)

Q: Are the 91615-323 and 91615-323LF mechanically interchangeable?

A: Yes. Both connectors share identical dimensions, pitch spacing (0.100"), row configuration (2 rows, 46 positions), mating height (10.81mm), and mounting type (surface mount). 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 The 91615-323LF is an active production part that is RoHS compliant, while the 91615-323 is obsolete and RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Can I use 91615-323LF as a replacement in existing assemblies designed for 91615-323?

A: Yes. The 91615-323LF is a direct substitute with no design modifications required. Existing PCB layouts, mating connectors, and assembly processes remain unchanged.

Q: Why should I transition from 91615-323 to 91615-323LF?

A: The 91615-323 is obsolete, creating long-term supply and support risks. The 91615-323LF is actively manufactured, ensuring availability and compliance with current environmental regulations (RoHS).

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 flammability ratings (UL94 V-0). Electrical performance is equivalent.

Q: What packaging is available for the 91615-323LF?
