FH34SW-12S-0.5SH(50) Equivalent & Substitute Parts

Part Overview

The FH34SW-12S-0.5SH(50) is a 12-position FFC/FPC connector manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle applications with 0.5mm pitch contacts. This connector features zero insertion force (ZIF) operation, gold-plated phosphor bronze contacts, and is rated for 50V and 0.5A per contact. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the FH34SW-12S-0.5SH(50) is determined by the following critical parameters:

• Position Count & Pitch: All substitutes maintain 12 positions at 0.5mm pitch
• Mounting Configuration: All substitutes are surface mount, right-angle connectors
• Electrical Ratings: All substitutes maintain 50V voltage rating and 0.5A current rating
• Termination Method: All substitutes use solder termination
• FFC/FPC Thickness: All substitutes maintain 0.30mm FFC/FPC thickness compatibility
• Locking Mechanism: All substitutes provide positive locking features (rotary lock, slide lock, or flip lock)
• Zero Insertion Force: All substitutes feature ZIF operation

The three substitute parts differ in contact configuration (top vs. top/bottom), housing materials, and operating temperature ranges, but maintain functional equivalence for the core 12-position, 0.5mm pitch, right-angle surface mount application.

Parameter Comparison

Engineering Selection Recommendations

FH34SRJ-12S-0.5SH(50) (Hirose Electric Co Ltd) is the primary substitute. This part maintains identical mechanical and electrical specifications to the original FH34SW-12S-0.5SH(50), with the addition of top and bottom contact configuration. The FH34SRJ series is active in production with RoHS compliance and extended operating temperature range (-55°C ~ 105°C). This part offers the highest compatibility for direct replacement applications.

10051922-1210ELF (Amphenol ICC/FCI) provides an alternative from a different manufacturer. This part maintains the 12-position, 0.5mm pitch, right-angle configuration with identical electrical ratings. The primary difference is bottom-contact-only configuration and increased height above board (1.30mm vs. 1.00mm). This part is suitable for applications where bottom-contact orientation is acceptable and PCB layout permits the increased height. RoHS compliance and active production status are confirmed.

AYF531235 (Panasonic Electric Works) offers a third-source option with top and bottom contact configuration. This part maintains all critical electrical and mechanical parameters, including 0.5mm pitch, 12 positions, and right-angle mounting. The part is RoHS compliant and actively produced. Operating temperature range matches the original specification (-55°C ~ 85°C).

All three substitutes are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can FH34SRJ-12S-0.5SH(50) directly replace FH34SW-12S-0.5SH(50)?

A: Yes. Both parts maintain 12 positions, 0.5mm pitch, surface mount right-angle configuration, 50V/0.5A ratings, and identical height above board (1.00mm). The FH34SRJ adds top and bottom contact capability, making it functionally compatible for top-contact applications. The FH34SRJ is the recommended primary substitute.

Q: What is the difference between top-contact and top/bottom-contact configurations?

A: Top-contact connectors (FH34SW) mate with cable on the top side only. Top/bottom-contact connectors (FH34SRJ, AYF531235) accommodate cable mating from either top or bottom, providing design flexibility. For applications requiring top-side mating only, both configurations are compatible.

Q: Why does 10051922-1210ELF have a different height above board?

A: The 10051922-1210ELF measures 1.30mm height above board compared to 1.00mm for the original and other substitutes. This difference results from internal mechanical design. PCB layout must accommodate this increased height. Verify clearance in your application before selection.

Q: Are all substitutes RoHS compliant?

A: Yes. FH34SRJ-12S-0.5SH(50), 10051922-1210ELF, and AYF531235 are all RoHS compliant. The original FH34SW-12S-0.5SH(50) RoHS status is not specified in available documentation.

Q: What is the operating temperature difference between substitutes?

A: FH34SRJ-12S-0.5SH(50) operates from -55°C to 105°C, providing 20°C extended upper temperature range compared to the original and other substitutes (-55°C to 85°C). Select FH34SRJ for applications requiring extended high-temperature operation.

Q: Can I use these substitutes interchangeably in the same design?

A: Substitutes are mechanically and electrically compatible for the 12-position, 0.5mm pitch, right-angle application. However, verify contact configuration requirements (top vs. top/bottom vs. bottom), height above board clearance, and operating temperature range for your specific application before final selection.

Q: What packaging options are available for these substitutes?

A: FH34SRJ-12S-0.5SH(50) is available in Cut Tape (CT) and Digi-Reel packaging. 10051922-1210ELF and AYF531235 are supplied in Tape & Reel (TR) packaging. Confirm packaging compatibility with your procurement and assembly processes.
