FH12-24S-0.5SH Equivalent & Substitute Parts

Part Overview

The FH12-24S-0.5SH is a 24-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 a flip lock mechanism, zero insertion force (ZIF) design, and bottom contact configuration suitable for flat flexible cable termination.

The main part number FH12-24S-0.5SH is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this connector footprint and electrical interface.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FH12-24S-0.5SH are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or remain within acceptable tolerances for direct substitution:

• Number of positions: 24
• Pitch: 0.020" (0.50mm)
• Mounting type: Surface mount, right angle
• Contact configuration: Bottom contacts
• Termination method: Solder
• Operating temperature range: -40°C ~ 85°C
• Material flammability: UL94 V-0
• Current rating: 0.5A minimum

Two substitute parts meet these core requirements with documented compatibility to the original FH12-24S-0.5SH specification.

Parameter Comparison

Engineering Selection Recommendations

FH12-24S-0.5SH(55) is the direct equivalent substitute for the obsolete FH12-24S-0.5SH. Both connectors are manufactured by Hirose Electric Co Ltd within the same FH12 series, share identical mechanical and electrical specifications, and maintain the same flip lock mechanism and contact configuration. The primary distinction is product status: FH12-24S-0.5SH(55) is active and ROHS3 compliant, whereas the original part is obsolete and RoHS non-compliant. This substitute provides equivalent form, fit, and function with improved regulatory compliance and supply availability.

2-1734592-4 manufactured by TE Connectivity AMP Connectors is a cross-manufacturer substitute that meets core electrical and mechanical requirements. This part maintains the 24-position, 0.5mm pitch, surface mount right-angle configuration with bottom contacts and solder termination. Notable differences include higher voltage rating (250V versus 50V), different housing material (LCP versus polyamide), slide lock mechanism (versus flip lock), and tapered cable end type (versus straight). These differences do not preclude substitution in applications where the original FH12-24S-0.5SH footprint and electrical interface are required, provided that mechanical envelope constraints and locking mechanism compatibility are evaluated for the specific application.

Frequently Asked Questions (FAQ)

Q: Can FH12-24S-0.5SH(55) be used as a direct replacement for FH12-24S-0.5SH?

A: Yes. FH12-24S-0.5SH(55) is the direct equivalent substitute. Both parts share identical position count (24), pitch (0.5mm), mounting configuration (surface mount right angle), contact arrangement (bottom), and electrical ratings (50V, 0.5A). The primary advantage of FH12-24S-0.5SH(55) is active product status and ROHS3 compliance.

Q: What are the key differences between FH12-24S-0.5SH(55) and 2-1734592-4?

A: Both parts maintain the same 24-position, 0.5mm pitch, surface mount right-angle configuration. Differences include: manufacturer (Hirose versus TE Connectivity), voltage rating (50V versus 250V), housing material (polyamide versus LCP), locking mechanism (flip lock versus slide lock), and cable end type (straight versus tapered). Height above board differs by 0.002" (0.05mm).

Q: Are there packaging differences between the substitute parts?

A: The original FH12-24S-0.5SH packaging is not specified. Both substitute parts are available in Tape & Reel (TR) packaging, which is standard for high-volume surface mount applications.

Q: Does the contact finish difference (Tin-Lead versus Gold) affect substitution?

A: Contact finish differences do not preclude substitution provided that the application does not impose specific contact material or corrosion resistance requirements. Gold-plated contacts (FH12-24S-0.5SH(55) and 2-1734592-4) offer superior corrosion resistance compared to tin-lead finish.

Q: Is the 0.002" (0.05mm) height difference between FH12-24S-0.5SH(55) and 2-1734592-4 significant?

A: The height difference (0.079" versus 0.081") is within typical PCB assembly tolerances and does not constitute a substitution barrier for standard applications. Applications with strict vertical clearance constraints should evaluate this parameter against specific design requirements.

Q: What is the significance of the different locking mechanisms?

A: FH12-24S-0.5SH and FH12-24S-0.5SH(55) both use flip lock mechanisms. The 2-1734592-4 uses a slide lock mechanism. Locking mechanism differences may affect mating/unmating procedures and mechanical interface compatibility with cable assemblies. Verify cable assembly compatibility before substitution.
