Key Parameters

Substitute Part Grouping Explanation

Substitution of the FX5-52P-SH3 is determined by strict equivalence across the following critical parameters:

• Series and Base Product Number: Both parts must belong to the FX5 series
• Position Count: Exactly 52 positions required
• Pitch Specification: 0.039" (1.00mm) pitch maintained
• Row Configuration: 2-row arrangement
• Connector Type: Header with center strip contacts
• Mounting Configuration: Surface mount, right-angle orientation
• Contact Finish: Gold plating
• Physical Height: 0.374" (9.50mm) above board
• Mechanical Features: Board guide and flange present

The FX5-52P-SH3(71) variant meets all these criteria and represents a direct functional equivalent with improved product status classification.

Parameter Comparison

Engineering Selection Recommendations

The FX5-52P-SH3(71) is the direct equivalent for the obsolete FX5-52P-SH3. Selection of the FX5-52P-SH3(71) provides the following advantages:

• Active Product Status: The FX5-52P-SH3(71) maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• RoHS Compliance: The substitute part achieves RoHS compliance, meeting current environmental and regulatory requirements
• Identical Electrical and Mechanical Specifications: All functional parameters remain unchanged, ensuring direct interchangeability in existing designs
• Standardized Packaging: Tray packaging provides improved handling and inventory management compared to bulk packaging

For applications where RoHS non-compliance is not a constraint, the original FX5-52P-SH3 remains functionally equivalent. However, procurement of the FX5-52P-SH3(71) is recommended for new designs and ongoing production to align with current regulatory standards and ensure supply availability.

Frequently Asked Questions (FAQ)

Q: Can the FX5-52P-SH3(71) be used as a direct replacement for the FX5-52P-SH3?

A: Yes. The FX5-52P-SH3(71) is electrically and mechanically identical to the FX5-52P-SH3 across all functional parameters, including position count, pitch, mounting configuration, and contact specifications. The primary differences are product status and RoHS compliance.

Q: What is the significance of the "(71)" designation in the part number?

A: The "(71)" suffix indicates a packaging or compliance variant within the FX5-52P-SH3 family. In this case, it denotes the RoHS-compliant version supplied in tray packaging.

Q: Are there any physical dimension differences between these parts?

A: No. Both parts share identical physical dimensions, including the 0.374" (9.50mm) height above board, 0.039" (1.00mm) pitch, and 52-position, 2-row configuration.

Q: What packaging formats are available?

A: The FX5-52P-SH3 is supplied in bulk packaging, while the FX5-52P-SH3(71) is supplied in tray packaging. Tray packaging provides improved component protection and handling during assembly operations.

Q: Does the RoHS compliance status affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical or mechanical performance. Both parts deliver identical functional characteristics.

Q: Is the FX5-52P-SH3(71) suitable for new product designs?

A: Yes. The FX5-52P-SH3(71) is the recommended choice for new designs due to its active product status, RoHS compliance, and assured long-term availability.
