Key Parameters

Substitute Part Grouping Explanation

Substitution of the FX5-40P-SH3 is determined by strict equivalence across the following critical parameters:

• Manufacturer and series consistency (Hirose Electric FX5 series)
• Electrical specifications: 40 positions, 1.00mm pitch, dual-row configuration
• Mechanical compatibility: Surface mount, right-angle orientation, center strip contact design
• Physical envelope: 0.374" (9.50mm) height above board
• Contact interface: Gold finish with board guide and flange features
• Environmental rating: MSL 1 (Unlimited moisture sensitivity level)

The substitute part FX5-40P-SH3(71) maintains identical electrical and mechanical specifications while differing only in packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The FX5-40P-SH3(71) is the direct functional equivalent of the FX5-40P-SH3, with identical electrical and mechanical specifications. Selection between these parts is determined by regulatory and procurement requirements:

FX5-40P-SH3(71) is the preferred selection for new designs and ongoing production due to active product status and RoHS compliance certification. This part satisfies modern regulatory requirements and ensures long-term supply chain continuity.

The FX5-40P-SH3 remains suitable for legacy system maintenance and repair applications where RoHS non-compliance does not present a constraint. Inventory availability is confirmed at 891 pieces.

Both parts are classified as REACH Unaffected and carry ECCN EAR99 designation.

Frequently Asked Questions (FAQ)

Q: Are FX5-40P-SH3 and FX5-40P-SH3(71) electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications: 40 positions, 1.00mm pitch, dual-row header configuration with gold-plated center strip contacts. Electrical performance and signal integrity are equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are product status, RoHS compliance, and packaging format. FX5-40P-SH3(71) is active production with RoHS compliance and tray packaging. FX5-40P-SH3 is obsolete with RoHS non-compliance and bulk packaging.

Q: Can I use FX5-40P-SH3(71) as a direct replacement in existing assemblies?

A: Yes. The mechanical envelope, mounting interface, and contact arrangement are identical. No PCB redesign or assembly process modification is required.

Q: What does the "(71)" designation indicate?

A: The "(71)" suffix identifies the packaging variant and product revision. This notation is used by Hirose Electric to distinguish packaging formats and compliance versions within the same base product family.

Q: Are there any compliance considerations when switching between these parts?

A: FX5-40P-SH3(71) carries RoHS compliance certification, while FX5-40P-SH3 does not. For applications subject to RoHS regulations, FX5-40P-SH3(71) is the required selection.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
