Engineering Selection Recommendations

FH12-6S-1SH(55) (Hirose Electric Co Ltd)

This is the direct equivalent from the original manufacturer. The FH12-6S-1SH(55) maintains identical mechanical and electrical specifications to the obsolete FH12-6S-1SH, with the primary difference being active product status and ROHS3 compliance. The contact finish upgrade from Tin-Lead to Gold provides enhanced corrosion resistance. This part is available in Tape & Reel packaging with substantial inventory (4300 pcs), making it the preferred choice for applications requiring exact form-fit-function compatibility with the original design.

1734798-6 (TE Connectivity AMP Connectors)

This TE Connectivity alternative meets all critical electrical and mechanical parameters with identical pitch, position count, and solder termination. The connector features a higher profile (0.126" vs 0.079"), lacks a locking mechanism, and operates within a narrower temperature range (-20°C minimum vs -40°C). This part is suitable for applications where the increased height does not present PCB layout constraints and where the lower temperature minimum is acceptable. RoHS compliance is confirmed.

84952-6 (TE Connectivity AMP Connectors)

This TE Connectivity option exceeds the original specifications with higher voltage (200V vs 50V) and current (1A vs 0.5A) ratings, providing design margin for future upgrades. The Slide Lock mechanism and Liquid Crystal Polymer housing offer enhanced mechanical durability. The height profile (0.101") falls between the original and the 1734798-6. This part maintains full operating temperature range compatibility (-40°C ~ 85°C) and ROHS3 compliance. Substantial inventory availability (4468 pcs) supports production requirements.

Frequently Asked Questions (FAQ)

Q: Can FH12-6S-1SH(55) be used as a direct replacement for FH12-6S-1SH?

A: Yes. The FH12-6S-1SH(55) is the direct manufacturer equivalent with identical mechanical and electrical specifications. The primary differences are active product status, ROHS3 compliance, and gold contact finish, which provides superior corrosion resistance compared to the original tin-lead finish.

Q: What are the key differences between the Hirose and TE Connectivity options?

A: The Hirose FH12-6S-1SH(55) maintains exact form-fit-function compatibility with the original design. TE Connectivity options (1734798-6 and 84952-6) offer alternative locking mechanisms and housing materials. The 84952-6 provides higher electrical ratings (200V, 1A) and maintains the full operating temperature range, while the 1734798-6 has a narrower temperature minimum (-20°C).

Q: Are there height profile differences that affect PCB layout?

A: Yes. The original FH12-6S-1SH and FH12-6S-1SH(55) have a height of 0.079" (2.00mm). The 84952-6 measures 0.101" (2.56mm), and the 1734798-6 measures 0.126" (3.20mm). PCB clearance must be verified for applications with height constraints.

Q: Which substitute offers the best compliance profile?

A: All active substitutes (FH12-6S-1SH(55), 1734798-6, and 84952-6) are RoHS compliant. The FH12-6S-1SH(55) and 84952-6 are ROHS3 compliant. The original FH12-6S-1SH is RoHS non-compliant.

Q: What is the difference between Flip Lock and Slide Lock mechanisms?

A: Both mechanisms provide zero insertion force (ZIF) operation and solder retention. The Flip Lock (FH12-6S-1SH and FH12-6S-1SH(55)) uses a hinged actuator, while the Slide Lock (84952-6) uses a sliding actuator. Both are functionally equivalent for cable retention and release.

Q: Can I use 84952-6 in applications designed for FH12-6S-1SH?

A: Yes, with design verification. The 84952-6 exceeds all critical electrical parameters and maintains full temperature range compatibility. The increased height (0.101" vs 0.079") and different locking mechanism require PCB layout confirmation and mechanical clearance validation.

Q: What packaging options are available?

A: FH12-6S-1SH(55) and 84952-6 are available in Tape & Reel (TR) packaging for automated assembly. The 1734798-6 is available in bulk packaging. Packaging selection depends on production volume and assembly process requirements.

Q: Is the contact finish difference between Tin-Lead and Gold significant?

A: Yes. Gold finish (FH12-6S-1SH(55)) provides superior corrosion resistance and is preferred for applications with extended shelf life or exposure to corrosive environments. Tin finish (1734798-6 and 84952-6) is suitable for standard industrial applications with normal environmental conditions.
