Engineering Selection Recommendations

The 77315-807-36LF is the direct substitute for the obsolete 77315-807-36. Both parts share identical mechanical and electrical mating characteristics, ensuring pin-for-pin compatibility in board-level applications.

The primary distinctions are:

Product Status: The substitute is active and currently available, whereas the main part is obsolete.
RoHS Compliance: The substitute meets RoHS requirements; the main part does not.
Contact Finish - Post: The substitute uses tin finish instead of tin-lead, eliminating lead content in accordance with environmental regulations.
Contact Finish Thickness - Post: The substitute specifies 78.7µin (2.00µm) compared to 150.0µin (3.81µm) on the main part.
Operating Temperature and Current Rating: The substitute provides documented specifications (-65°C ~ 125°C operating range, 3A per contact), whereas these parameters are not specified for the main part.

For new designs or component replacement in existing applications, the 77315-807-36LF is the appropriate selection due to its active status, regulatory compliance, and documented performance parameters.

Frequently Asked Questions (FAQ)

Q: Are the 77315-807-36 and 77315-807-36LF mechanically interchangeable?

A: Yes. Both parts maintain identical pitch (0.100"), position count (36), contact geometry, mounting style (through-hole right-angle), and board-level footprint. They are direct mechanical substitutes.

Q: What does the "LF" suffix in 77315-807-36LF indicate?

A: The "LF" designation indicates lead-free construction. The post contact finish is tin instead of tin-lead, making the part compliant with RoHS regulations.

Q: Can I use the 77315-807-36LF as a replacement in existing assemblies designed for the 77315-807-36?

A: Yes. The electrical and mechanical parameters are compatible. The primary change is the elimination of lead in the post finish, which is a regulatory improvement with no functional impact on connector performance.

Q: What is the difference in contact finish thickness between these parts?

A: The main part specifies 150.0µin (3.81µm) post finish thickness, while the substitute specifies 78.7µin (2.00µm). Both thicknesses are within acceptable engineering tolerances for this connector category and do not affect mating performance.

Q: Why is the main part listed as obsolete?

A: The 77315-807-36 is obsolete due to regulatory shifts toward lead-free manufacturing. The 77315-807-36LF represents the current production equivalent and is the recommended part for all new applications.

Q: Are there any packaging differences between these parts?

A: The main part packaging is not specified in the documentation. The substitute is supplied in bulk packaging. Confirm packaging requirements with your procurement department.

Q: What is the current availability of the 77315-807-36LF?

A: The substitute is in active production status with 698 pieces currently in stock as new original inventory.
