Substitute Part Grouping Explanation

The FX5-52S2A-DSA(71) qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Identical number of positions: 52
• Identical pitch specification: 0.039" (1.00mm)
• Identical number of rows: 2
• Identical connector type: Receptacle, Outer Shroud Contacts
• Identical mounting type: Through Hole
• Identical contact finish: Gold
• Identical height above board: 0.366" (9.30mm)
• Same base product number: FX5
• Same manufacturer: Hirose Electric Co Ltd

The primary distinction between the main part and its substitute is product status and packaging configuration, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The FX5-52S2A-DSA(71) is the direct functional equivalent of the FX5-52S2A-DSA. Selection between these parts should be based on the following criteria:

For new designs or applications requiring regulatory compliance: The FX5-52S2A-DSA(71) is the appropriate choice, as it carries RoHS Compliant status and Active product status, ensuring long-term availability and compliance with current environmental regulations.

For legacy system maintenance or existing inventory management: The FX5-52S2A-DSA remains electrically and mechanically interchangeable where RoHS non-compliance is not a constraint.

Packaging considerations: The FX5-52S2A-DSA(71) is supplied in Tray packaging, which may affect procurement workflows and handling procedures compared to the unspecified packaging of the original part.

Frequently Asked Questions (FAQ)

Q: Are the FX5-52S2A-DSA and FX5-52S2A-DSA(71) electrically identical?

A: Yes. Both parts share identical electrical specifications including 52 positions, 0.039" (1.00mm) pitch, gold contact finish, and receptacle configuration with outer shroud contacts.

Q: Can the FX5-52S2A-DSA(71) be used as a direct replacement in existing applications?

A: Yes, provided that RoHS compliance requirements are met or not applicable to the application. The mechanical and electrical parameters are identical, ensuring PCB footprint and mating compatibility.

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

A: The "(71)" designation indicates a variant of the base FX5-52S2A-DSA part number. In this case, it represents the active production version with RoHS Compliant status and Tray packaging.

Q: Why is the original FX5-52S2A-DSA marked as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation of a product line in favor of updated or compliant variants. The FX5-52S2A-DSA(71) represents the current active equivalent within the same product family.

Q: Are there any height or footprint differences between these parts?

A: No. Both parts specify identical height above board of 0.366" (9.30mm) and share the same mechanical footprint, ensuring direct PCB compatibility.

Q: What packaging format should be expected when ordering the FX5-52S2A-DSA(71)?

A: The FX5-52S2A-DSA(71) is supplied in Tray packaging. Confirm packaging requirements with your procurement process before ordering.
