FX5-40P-SH Equivalent & Substitute Parts
Part Overview
The FX5-40P-SH is a 40-position rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle applications with center strip contacts and gold plating. This connector is classified as obsolete, which necessitates identification of active equivalent parts to ensure continued design support and procurement availability. The FX5 series provides standardized rectangular connector solutions for applications requiring dual-row, 1.00mm pitch configurations with board-mounted header functionality.

Substitute Part Grouping Explanation
Substitution eligibility for the FX5-40P-SH is determined by strict equivalence across the following critical parameters:
- Connector Type & Configuration: Header with center strip contacts, dual-row arrangement
- Electrical Specifications: 40 positions at 1.00mm pitch
- Mechanical Interface: Surface mount, right-angle orientation with board guide and flange
- Contact Material: Gold finish for consistent electrical performance
- Physical Envelope: 0.256" (6.50mm) height above board
- Series Compatibility: FX5 series designation
The substitute part FX5-40P-SH(71) maintains identical electrical and mechanical specifications while differing in product status and packaging configuration. This substitution is valid for applications where the connector footprint, contact arrangement, and mounting interface are the primary design constraints.

Engineering Selection Recommendations
The FX5-40P-SH(71) is the direct active equivalent for the obsolete FX5-40P-SH. Selection of the substitute part is based on the following engineering criteria:
Product Status: The FX5-40P-SH(71) maintains active product status with Hirose Electric Co Ltd, ensuring continued manufacturing support, availability, and technical documentation access. The original FX5-40P-SH is obsolete and subject to discontinuation.
Regulatory Compliance: The FX5-40P-SH(71) is RoHS Compliant, meeting current environmental and material restriction requirements. The original part is RoHS non-compliant, which may present procurement and regulatory challenges in applications subject to RoHS directives.
Electrical and Mechanical Equivalence: Both parts maintain identical specifications across all functional parameters including position count, pitch, mounting configuration, contact finish, and physical dimensions. No design modification is required for substitution.
Packaging Consideration: The substitute part is supplied in Tray packaging, which is standard for production environments and provides appropriate protection for surface mount components.
Frequently Asked Questions (FAQ)
Q: Are the FX5-40P-SH and FX5-40P-SH(71) electrically identical?
A: Yes. Both parts maintain identical electrical specifications: 40 positions, 1.00mm pitch, dual-row configuration, gold contact finish, and center strip contact design. No electrical performance difference exists between the two parts.
Q: Can the FX5-40P-SH(71) be used as a direct replacement on existing PCB designs?
A: Yes. The FX5-40P-SH(71) maintains identical mechanical dimensions, mounting interface, and footprint. No PCB redesign is required for substitution.
Q: What is the significance of the "(71)" designation in FX5-40P-SH(71)?
A: The "(71)" suffix indicates a specific packaging and compliance variant within the FX5-40P-SH product line. In this case, it denotes Tray packaging and RoHS Compliant status.
Q: Why is the original FX5-40P-SH listed as obsolete?
A: Product obsolescence is determined by the manufacturer based on market demand, production economics, and product lifecycle management. The active equivalent FX5-40P-SH(71) provides continued access to the same connector functionality.
Q: Are there any compliance differences between the two parts?
A: Yes. The FX5-40P-SH(71) is RoHS Compliant, while the original FX5-40P-SH is RoHS non-compliant. For applications subject to RoHS directives, the substitute part is required.
Q: What packaging is used for the FX5-40P-SH(71)?
A: The FX5-40P-SH(71) is supplied in Tray packaging, which is standard for surface mount components and suitable for automated assembly processes.
