FH19SC-6S-0.5SH(05) Equivalent & Substitute Parts

Part Overview

The FH19SC-6S-0.5SH(05) is a 6-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 functionally equivalent alternatives for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

• Number of Positions: 6
• Pitch: 0.020" (0.50mm)
• Mounting Type: Surface Mount, Right Angle
• Voltage Rating: 50V
• Current Rating: 0.5A
• Contact Material: Phosphor Bronze or equivalent copper alloy
• Contact Finish: Gold
• Material Flammability Rating: UL94 V-0
• Operating Temperature Range: -55°C ~ 85°C (minimum requirement)
• Locking Feature: Flip Lock

Three substitute parts meet these criteria with varying contact configurations and mechanical specifications:

1. FH19C-6S-0.5SH(10) (Hirose Electric Co Ltd) – Same manufacturer, active product status, bottom-contact configuration matching the original design intent
2. 5034800600 (Molex) – Top and bottom contact configuration, active product status, alternative housing material composition
3. AYF530635 (Panasonic Electric Works) – Top and bottom contact configuration, active product status, extended mating cycle rating

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: FH19C-6S-0.5SH(10)

The FH19C-6S-0.5SH(10) is the preferred substitute due to identical contact configuration (bottom-contact), matching electrical specifications, and active product status from the original manufacturer. This part maintains design continuity with the obsolete FH19SC-6S-0.5SH(05) while offering current availability and ROHS3 compliance. The FH19C series represents the direct evolution of the FH19SC series within Hirose's product portfolio.

Secondary Recommendations: 5034800600 and AYF530635

Both alternatives provide equivalent electrical performance and meet all critical substitution parameters. However, both feature top and bottom contact configurations, which may require PCB layout modifications depending on the original design intent. The 5034800600 operates at a reduced lower temperature limit (-40°C versus -55°C) and supports only 10 mating cycles compared to the original specification of 20 cycles. The AYF530635 maintains the full -55°C ~ 85°C operating range and 20 mating cycle rating, making it suitable for applications requiring extended thermal and mechanical durability.

All three substitute parts carry ROHS3 compliance and unlimited moisture sensitivity rating, meeting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can FH19C-6S-0.5SH(10) be used as a direct replacement for FH19SC-6S-0.5SH(05)?

A: Yes. Both parts share identical electrical ratings (50V, 0.5A), operating temperature range (-55°C ~ 85°C), pitch (0.50mm), position count (6), and bottom-contact configuration. The primary difference is the FFC/FCB thickness (0.20mm versus 0.30mm) and height above board (0.035" versus 0.037"), which are minor mechanical variations that do not affect electrical compatibility. The FH19C-6S-0.5SH(10) is the recommended substitute.

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

A: Bottom-contact connectors (FH19SC and FH19C) interface with FFC/FPC cables from the bottom side only. Top-and-bottom contact connectors (5034800600 and AYF530635) accept cables from either the top or bottom surface. If your PCB layout is designed for bottom-contact insertion, the top-and-bottom alternatives may require layout modification or cable routing changes.

Q: Why does the Molex 5034800600 have a lower operating temperature minimum?

A: The 5034800600 specifies -40°C ~ 85°C, compared to -55°C ~ 85°C for the other alternatives. This difference reflects the material composition and design specifications of Molex's BackFlip series. Applications requiring operation below -40°C should use FH19C-6S-0.5SH(10) or AYF530635.

Q: Are all substitute parts RoHS compliant?

A: Yes. FH19C-6S-0.5SH(10), 5034800600, and AYF530635 are all ROHS3 compliant. The original FH19SC-6S-0.5SH(05) does not specify RoHS status due to its obsolete classification.

Q: What is the significance of mating cycle ratings?

A: Mating cycles indicate the number of times a connector can be mated and unmated before performance degradation. The original FH19SC and recommended FH19C both support 20 cycles. The Molex 5034800600 supports only 10 cycles, making it less suitable for applications requiring frequent connector cycling. The AYF530635 maintains the 20-cycle rating.

Q: Can I use these connectors interchangeably in the same application?

A: Electrical interchangeability is confirmed for all three substitutes. However, mechanical interchangeability depends on PCB layout design. Bottom-contact designs (FH19C-6S-0.5SH(10)) are direct mechanical replacements. Top-and-bottom designs (5034800600, AYF530635) may require PCB modification if the original layout accommodates only bottom-contact insertion.
