FH12-8S-1SH Equivalent & Substitute Parts

Part Overview

The FH12-8S-1SH is an 8-position FFC/FPC connector manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle applications with 1.00mm pitch contacts. This connector features a flip lock mechanism, zero insertion force (ZIF) operation, and solder termination. The main part is currently obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the FH12-8S-1SH is determined by the following critical parameters:

• Position Count & Pitch: 8 positions at 0.039" (1.00mm) pitch (non-negotiable)
• Mounting Configuration: Surface mount, right-angle orientation
• Contact Placement: Bottom-mounted contacts
• Termination Method: Solder termination
• Electrical Ratings: Minimum 50V voltage rating and 0.5A current rating
• Operating Temperature Range: -40°C to 85°C minimum
• Mechanical Features: Zero insertion force (ZIF) operation and solder retention

The substitute parts listed below maintain these core parameters while offering improved product status, compliance certifications, and availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: FH12-8S-1SH(55)

The FH12-8S-1SH(55) is the direct equivalent from Hirose Electric Co Ltd. It maintains identical mechanical and electrical specifications to the original part while offering active product status and ROHS3 compliance. The primary difference is the contact finish upgrade from tin-lead to gold, which improves corrosion resistance. This part is recommended for applications requiring minimal design changes and maximum compatibility with the original FH12 series specifications.

Alternative Substitutes: Molex 0522710869 and 0522710879

Both Molex parts (0522710869 and 0522710879) are FPC bottom-contact connectors with 8 positions at 1.00mm pitch. These parts maintain the critical electrical parameters (50V, 0.5A) and operating temperature range. Key differences include increased height above board (3.00mm versus 2.00mm), slide lock mechanism instead of flip lock, and tapered cable end type. These parts are suitable for applications where the increased height and different locking mechanism are compatible with the PCB layout. Both are ROHS3 compliant and active products with 30 mating cycles.

Alternative Substitute: Molex 0522070860

The Molex 0522070860 differs in contact placement (top-mounted rather than bottom-mounted) and is therefore suitable only for applications where the connector orientation can be reversed. This part offers higher electrical ratings (125V, 1A) and improved mating cycles (30 versus 20). The minimum operating temperature is -30°C, which may not be suitable for applications requiring -40°C operation.

Compliance Consideration

All substitute parts are ROHS3 compliant and active products, addressing the obsolescence and compliance limitations of the original FH12-8S-1SH.

Frequently Asked Questions (FAQ)

Q: Can FH12-8S-1SH(55) be used as a direct replacement for FH12-8S-1SH?

A: Yes. FH12-8S-1SH(55) maintains identical mechanical and electrical specifications. The gold contact finish provides improved corrosion resistance compared to the original tin-lead finish. Both parts are from the same manufacturer and series.

Q: What are the key differences between Hirose FH12-8S-1SH(55) and Molex 0522710869?

A: Both maintain 8 positions, 1.00mm pitch, bottom contact placement, and 50V/0.5A ratings. Differences include: height above board (2.00mm versus 3.00mm), locking mechanism (flip lock versus slide lock), cable end type (straight versus tapered), and mating cycles (20 versus 30). PCB layout compatibility must be verified before substitution.

Q: Is Molex 0522070860 compatible with the FH12-8S-1SH?

A: Molex 0522070860 has top-mounted contacts instead of bottom-mounted contacts, requiring PCB layout reversal. The minimum operating temperature is -30°C rather than -40°C. Electrical ratings are higher (125V, 1A). This part is suitable only if the connector orientation can be changed in the design.

Q: What packaging options are available for these substitute parts?

A: FH12-8S-1SH(55), 0522710869, 0522710879, and 0522070860 are all available in Tape & Reel (TR) packaging for automated assembly.

Q: Are all substitute parts RoHS compliant?

A: Yes. FH12-8S-1SH(55) and all Molex substitutes (0522710869, 0522710879, 0522070860) are ROHS3 compliant. The original FH12-8S-1SH is RoHS non-compliant.

Q: What is the difference between flip lock and slide lock mechanisms?

A: Flip lock (FH12 series) uses a hinged actuator that flips to secure the cable. Slide lock (Molex 52271 series) uses a sliding actuator mechanism. Both provide zero insertion force operation and solder retention. The choice depends on PCB space constraints and assembly process compatibility.
