Key Parameters

Substitute Part Grouping Explanation

Substitution for the 75915-340 is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (40-position receptacle, female socket)
• Mating pitch specification (0.100" / 2.54mm)
• Mounting and termination method (through-hole solder)
• Contact finish material and specification (gold plating on mating surface)
• Fastening mechanism (push-pull)
• Insulation material and flammability rating (thermoplastic glass-filled, UL94 V-0)

The substitute part 75915-340LF maintains identical electrical and mechanical specifications while differing in product status (active vs. obsolete) and regulatory compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The 75915-340LF serves as the direct functional equivalent to the obsolete 75915-340. Both parts are electrically and mechanically identical across all specified parameters. The primary distinctions are:

Product Status: The 75915-340LF is active production, whereas the 75915-340 is obsolete. For new designs or ongoing procurement, the 75915-340LF is the appropriate selection.

Regulatory Compliance: The 75915-340LF is RoHS compliant and REACH affected, reflecting current regulatory requirements. The original 75915-340 is RoHS non-compliant and REACH unaffected. Selection should align with applicable regulatory frameworks for the end application.

Packaging: The 75915-340LF is supplied in tube packaging, providing standardized handling and storage compared to the unspecified packaging of the original part.

Frequently Asked Questions (FAQ)

Q: Are the 75915-340 and 75915-340LF mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including connector type, position count, pitch, mounting method, and physical dimensions. Direct substitution is possible without PCB redesign.

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

A: The primary differences are product status (obsolete vs. active), RoHS compliance posture, and REACH regulatory classification. Electrical and mechanical performance are equivalent.

Q: Can I use the 75915-340LF in place of the 75915-340 in existing designs?

A: Yes, the 75915-340LF is a direct substitute. Verify that RoHS compliance requirements for your application are satisfied by the substitute part.
