Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-1571551-1 serves as the direct active equivalent for the obsolete 7-1437536-2. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 7-1437536-2 is classified as obsolete, while the 5-1571551-1 maintains active product status, ensuring continued availability and manufacturing support.

Regulatory Compliance: The substitute part 5-1571551-1 is RoHS Compliant, whereas the main part is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in most markets.

Material Specifications: The substitute part includes documented housing material (Polycyclohexylenedimethylene Terephthalate/PCT Polyester) with UL94 V-0 flammability rating, providing enhanced material traceability and safety certification compared to the main part.

Contact Specifications: Both parts maintain identical mating contact specifications (gold-plated beryllium copper at 25.0µin thickness). The substitute part provides enhanced post contact specifications with gold plating and nickel base material, compared to the unspecified post finish on the main part.

Electrical and Mechanical Compatibility: All critical electrical parameters (contact resistance, operating temperature range) and mechanical parameters (pitch, row spacing, termination post length, mounting type) are identical between the two parts, ensuring direct functional substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 5-1571551-1 be used as a direct replacement for the 7-1437536-2 in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications for all critical parameters including pin count (36 positions), pitch (0.100"), row spacing (0.6"), contact resistance (10mOhm), operating temperature range (-55°C ~ 125°C), and termination method (solder through-hole). The substitute part is electrically and mechanically compatible with existing PCB layouts and component designs.

Q: What are the differences between these two parts?

A: The primary differences are product status and compliance. The 7-1437536-2 is obsolete and RoHS non-compliant, while the 5-1571551-1 is active and RoHS Compliant. The substitute part includes documented housing material (PCT Polyester) with UL94 V-0 flammability rating. Post contact specifications differ: the substitute provides gold-plated nickel posts versus unspecified brass posts on the main part. Mating contact specifications remain identical.

Q: Are the pitch and row spacing identical between these parts?

A: Yes. Both parts feature 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) post pitch with 0.6" (15.24mm) row spacing. The 36-position DIP configuration (2 x 18 arrangement) is identical, ensuring footprint compatibility on PCBs.

Q: What is the operating temperature range for both parts?

A: Both the 7-1437536-2 and 5-1571551-1 operate across the identical temperature range of -55°C to 125°C, supporting applications requiring extended thermal performance.

Q: How do the contact materials compare?

A: Mating contacts are identical in both parts: gold-plated beryllium copper at 25.0µin (0.63µm) thickness. Post contact material differs: the main part uses brass with unspecified finish, while the substitute uses nickel with gold plating at 25.0µin thickness. Both configurations maintain the specified 10mOhm contact resistance.

Q: Is the 5-1571551-1 suitable for RoHS-compliant applications?

A: Yes. The 5-1571551-1 is RoHS Compliant, making it suitable for applications and markets requiring RoHS compliance. The 7-1437536-2 is RoHS non-compliant and should not be used in RoHS-restricted applications.

Q: What mounting method is used for both parts?

A: Both parts use through-hole solder termination with identical termination post length of 0.125" (3.18mm), compatible with standard PCB assembly processes and wave soldering equipment.

Q: Are there any inventory considerations for these parts?

A: The 7-1437536-2 is obsolete with limited remaining inventory (1065 pcs reported). The 5-1571551-1 is active with current inventory availability (1031 pcs reported), providing reliable long-term sourcing for new designs and production requirements.
