Engineering Selection Recommendations

The 87409-145LF is the direct substitute for the obsolete 87409-145. Both parts are electrically and mechanically identical across all critical parameters: 90-position connectivity, 1.27mm pitch, surface mount configuration, shrouded 4-wall design, and push-pull fastening.

The primary distinction is product status and compliance posture. The 87409-145LF is an active product with RoHS compliance and REACH affected status, whereas the 87409-145 is obsolete and RoHS non-compliant. The 87409-145LF also specifies Tin post finish versus Tin-Lead on the original part, reflecting modern lead-free manufacturing standards.

For new designs, field service replacements, or production continuity, the 87409-145LF is the appropriate selection. Both parts share identical packaging specifications, mounting footprints, and performance characteristics, ensuring direct substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Are the 87409-145 and 87409-145LF mechanically interchangeable?

A: Yes. Both parts feature identical connector geometry, pitch spacing (1.27mm), shrouding configuration, and surface mount footprint. They are direct mechanical substitutes with no PCB layout or assembly process changes required.

Q: What is the difference between the Tin-Lead and Tin post finishes?

A: The 87409-145 uses Tin-Lead post finish, while the 87409-145LF uses Tin post finish. This reflects the transition to lead-free manufacturing. Both finishes provide equivalent solderability and electrical performance in standard reflow processes.

Q: Why is the 87409-145 marked as obsolete?

A: The 87409-145 has been superseded by the 87409-145LF, which offers improved compliance status (RoHS compliant) and lead-free construction. Amphenol ICC has transitioned production to the LF variant.

Q: Can I use the 87409-145LF in applications originally designed for the 87409-145?

A: Yes. The 87409-145LF maintains full electrical and mechanical compatibility. It is suitable for all applications previously served by the 87409-145, including general purpose and military use cases.

Q: What is the packaging difference between these parts?

A: The 87409-145 packaging is not specified in the datasheet. The 87409-145LF is supplied in Tube packaging. Confirm packaging requirements with your procurement or supply chain team.

Q: Are there any temperature or current rating differences?

A: No. Both parts operate across -55°C to 130°C and are rated for 1A DC current. Environmental performance is identical.

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

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
