FH19SC-12S-0.5SH(99) Equivalent & Substitute Parts

Part Overview

The FH19SC-12S-0.5SH(99) is a 12-position FFC/FPC connector manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle applications with 0.50mm pitch contacts. This connector features bottom contact configuration, flip lock mechanism, and zero insertion force (ZIF) operation. The part is currently obsolete, necessitating identification of equivalent and substitute components for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FH19SC-12S-0.5SH(99) is determined by the following critical parameters:

• Position Count & Pitch: 12 positions at 0.50mm pitch (non-negotiable for mechanical and electrical compatibility)
• Mounting Configuration: Surface mount, right-angle orientation
• Electrical Ratings: 50V voltage rating and 0.5A current rating per contact
• Contact Configuration: Bottom or top/bottom contact arrangement
• Termination Method: Solder termination
• Locking Mechanism: Flip lock or equivalent retention feature
• Material Compliance: Halogen-free housing, UL94 V-0 flammability rating, RoHS compliance

Two substitute categories are identified:

Category 1 - Parametric Equivalent (Same Contact Configuration) FH19SC-12S-0.5SH(09) maintains identical contact configuration (bottom contacts) and mechanical envelope, differing only in packaging and product status.

Category 2 - Functional Equivalent (Enhanced Contact Configuration) FH34SRJ-12S-0.5SH(99) and AYF531235 provide top and bottom contact configuration, enabling broader application flexibility while maintaining core electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Mechanical Envelope) FH19SC-12S-0.5SH(09) is the parametric equivalent, maintaining bottom contact configuration and identical electrical specifications. This part is in Last Time Buy status with higher inventory availability (9464 pcs), making it suitable for near-term production requirements. Both parts share the same base product number (FH19) and are RoHS compliant.

For Active Production (Recommended Long-Term Solution) FH34SRJ-12S-0.5SH(99) is an active product from Hirose Electric Co Ltd with superior availability (3035 pcs) and extended operating temperature range (-55°C ~ 105°C). The top and bottom contact configuration provides design flexibility for applications requiring dual-sided connectivity. This part carries ROHS3 compliance and features enhanced locking mechanisms (rotary lock with backlock).

For Cross-Manufacturer Substitution AYF531235 from Panasonic Electric Works is an active product with the highest inventory level (16035 pcs). It maintains all critical electrical parameters and offers top and bottom contact configuration. This part is suitable for applications where manufacturer diversification is acceptable and provides extended supply chain security.

Frequently Asked Questions (FAQ)

Q: Can FH19SC-12S-0.5SH(09) be used as a direct replacement for FH19SC-12S-0.5SH(99)? A: Yes. Both parts share identical electrical ratings (50V, 0.5A), mechanical configuration (12 positions, 0.50mm pitch, surface mount right-angle), contact arrangement (bottom), and locking mechanism (flip lock). The primary difference is product status and packaging format. FH19SC-12S-0.5SH(09) is in Last Time Buy status.

Q: What is the key difference between bottom-contact and top/bottom-contact configurations? A: Bottom-contact connectors (FH19SC series) provide single-sided connectivity suitable for standard FFC/FPC applications. Top and bottom-contact connectors (FH34SRJ and AYF531235) enable dual-sided signal routing, allowing greater design flexibility for complex interconnect requirements.

Q: Is FH34SRJ-12S-0.5SH(99) compatible with existing PCB layouts designed for FH19SC-12S-0.5SH(99)? A: Mechanical compatibility exists for mounting footprint and pitch alignment. However, the enhanced contact configuration and different locking mechanism (rotary lock with backlock versus flip lock) require PCB layout verification. The height above board differs slightly (1.00mm versus 0.95mm).

Q: What are the compliance differences between these parts? A: All four parts meet UL94 V-0 flammability requirements and are RoHS compliant. FH34SRJ-12S-0.5SH(99) carries ROHS3 compliance. AYF531235 is REACH unaffected. All parts are halogen-free or LCP-based, meeting environmental standards.

Q: Which part should be selected for new designs? A: FH34SRJ-12S-0.5SH(99) is recommended for new designs due to active product status, extended operating temperature range (-55°C ~ 105°C), and superior long-term availability. AYF531235 provides cross-manufacturer redundancy with the highest current inventory level.

Q: Are there packaging differences that affect procurement? A: FH19SC-12S-0.5SH(99) is supplied in standard packaging. FH19SC-12S-0.5SH(09), FH34SRJ-12S-0.5SH(99), and AYF531235 are supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly.
