Substitute Part Grouping Explanation

Substitution eligibility for the FH19SC-14S-0.5SH(09) is determined by the following critical parameters:

Position Count: 14 positions (exact match required)
Pitch: 0.50mm (0.020") (exact match required)
Mounting Configuration: Surface mount, right angle (exact match required)
Contact Arrangement: Bottom or top/bottom contacts (bottom contacts are primary requirement)
Voltage Rating: Minimum 50V
Current Rating: Minimum 0.5A
Operating Temperature Range: Must encompass -55°C to 85°C minimum
Termination: Solder (exact match required)
Compliance: RoHS compliant, UL94 V-0 flammability rating

Two substitute parts meet these criteria with varying degrees of compatibility based on contact configuration and thermal operating range.

Engineering Selection Recommendations

FH34SRJ-14S-0.5SH(50) (Hirose Electric Co Ltd)

This substitute offers the closest electrical and mechanical compatibility with the original FH19SC-14S-0.5SH(09). Both are Hirose products with identical position count, pitch, mounting configuration, voltage, and current ratings. The FH34SRJ features an extended operating temperature range (-55°C ~ 105°C) that exceeds the original specification. The primary design difference is the top and bottom contact configuration versus bottom-only contacts on the original part. This part maintains Active product status, ensuring long-term availability and supply chain stability.

FFC2B35-14-G (GCT)

This substitute maintains bottom contact configuration identical to the original FH19SC-14S-0.5SH(09), with matching position count, pitch, mounting type, and voltage rating. However, the current rating is 0.4A, which is below the original 0.5A specification. The operating temperature range (-25°C ~ 85°C) does not extend to the lower -55°C limit of the original part. The connector height above board is significantly greater (2.00mm versus 0.95mm), which may impact PCB layout compatibility. This part is Active status and ROHS3 compliant. Selection of this substitute requires verification that the reduced current rating and narrower temperature range are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can FH34SRJ-14S-0.5SH(50) be used as a direct replacement for FH19SC-14S-0.5SH(09)?

A: The FH34SRJ-14S-0.5SH(50) is electrically and mechanically compatible based on position count, pitch, mounting configuration, voltage, and current ratings. The primary design difference is the addition of top contacts in addition to bottom contacts. PCB layout and mating cable compatibility must be evaluated for your specific application.

Q: What is the significance of the contact configuration difference (bottom only versus top and bottom)?

A: The FH19SC features bottom contacts only, while the FH34SRJ features both top and bottom contacts. This affects the mating interface and cable design. The FH34SRJ provides additional contact points but requires compatible cable design.

Q: Why is the FFC2B35-14-G listed as a substitute if the current rating is lower?

A: The FFC2B35-14-G meets the core substitution criteria of 14 positions, 0.50mm pitch, surface mount right-angle configuration, and bottom contact type. However, the 0.4A current rating is below the original 0.5A specification. This part is suitable only for applications where the actual current draw does not exceed 0.4A.

Q: Does the height difference between these connectors affect PCB design?

A: Yes. The FH19SC has a height of 0.95mm, the FH34SRJ is 1.00mm, and the FFC2B35-14-G is 2.00mm above the board. The FFC2B35-14-G's significantly greater height may require PCB layout modifications and clearance verification.

Q: Are all three parts RoHS compliant?

A: Yes. The FH19SC-14S-0.5SH(09) and FH34SRJ-14S-0.5SH(50) are RoHS Compliant. The FFC2B35-14-G is ROHS3 Compliant. All meet RoHS requirements.

Q: What is the operating temperature consideration for the FFC2B35-14-G?

A: The FFC2B35-14-G operates from -25°C to 85°C, which does not extend to the -55°C lower limit of the original FH19SC. Applications requiring operation below -25°C cannot use this substitute.
