FX5-20P-SH3 Equivalent & Substitute Parts

Part Overview

The FX5-20P-SH3 is a 20-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 functionally equivalent alternatives for ongoing design support and procurement continuity. The FX5 series provides standardized interconnect solutions for applications requiring dual-row, 1.00mm pitch header configurations with board-mounted positioning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX5-20P-SH3 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header with center strip contacts, dual-row arrangement
• Electrical Interface: 20 positions at 1.00mm pitch
• Mechanical Mounting: Surface mount, right-angle orientation with board guide and flange
• Contact Material: Gold plating for consistent electrical performance
• Physical Envelope: 0.374" (9.50mm) height above board

The substitute part FX5-20P-SH3(71) maintains identical electrical and mechanical specifications while differing only in packaging format (tray) and product status (active). This variant is sourced from the same manufacturer and series, ensuring design compatibility without modification to PCB layouts or mating connector specifications.

Parameter Comparison

Engineering Selection Recommendations

The FX5-20P-SH3(71) is the direct functional equivalent for the obsolete FX5-20P-SH3. Selection of the substitute part is based on the following engineering criteria:

Product Status: The FX5-20P-SH3(71) carries active product status, ensuring continued manufacturer support, availability, and supply chain stability compared to the obsolete designation of the original part.

Regulatory Compliance: The substitute part achieves RoHS compliance, meeting current environmental and regulatory requirements for new designs and procurement cycles. The original part is RoHS non-compliant.

Electrical & Mechanical Equivalence: All functional parameters—connector type, position count, pitch, mounting configuration, contact finish, and physical dimensions—are identical between the main part and substitute, ensuring direct PCB compatibility without design modification.

Packaging Consideration: The substitute is supplied in tray packaging rather than bulk format. This affects handling and storage procedures but does not alter component functionality or performance.

Frequently Asked Questions (FAQ)

Q: Can FX5-20P-SH3(71) be used as a direct replacement for FX5-20P-SH3 without PCB modification?

A: Yes. The FX5-20P-SH3(71) maintains identical electrical and mechanical specifications, including position count, pitch, mounting type, height above board, and contact finish. No PCB layout changes are required.

Q: What is the difference between FX5-20P-SH3 and FX5-20P-SH3(71)?

A: The parts are electrically and mechanically identical. The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. compliant), and packaging format (bulk vs. tray). The suffix "(71)" indicates the tray packaging variant.

Q: Why is the original FX5-20P-SH3 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this specific part number. The FX5-20P-SH3(71) represents the current active equivalent within the same series.

Q: Does the tray packaging of FX5-20P-SH3(71) affect component performance?

A: No. Packaging format affects logistics, storage, and handling procedures but does not alter electrical performance, mechanical fit, or functional characteristics of the connector.

Q: Is RoHS compliance a functional requirement for substitution?

A: RoHS compliance is a regulatory and procurement requirement for many applications and markets. The FX5-20P-SH3(71) meets current RoHS standards, while the original part does not. This may be a critical factor for new designs or regions with environmental regulations.

Q: Are there any other substitutes for the FX5-20P-SH3 within the FX5 series?

A: Based on the provided data, FX5-20P-SH3(71) is the identified equivalent. Any other potential alternatives would require verification against the same critical parameters: 20 positions, 1.00mm pitch, dual-row header configuration, surface mount right-angle mounting, and gold contact finish.
