Substitute Part Grouping Explanation

The substitute part FX2C2-52P-1.27DSA(71) is classified as a direct equivalent based on the following matching parameters:

• Number of positions: 52
• Number of rows: 2
• Pitch spacing: 1.27mm
• Connector type: Plug
• Mounting type: Through Hole
• Termination method: Solder
• Contact finish: Gold
• Connector style: Center Strip Contacts
• Board-to-board application type
• Series designation: FX2

The primary distinction between the main part and the substitute is product status and packaging configuration. The substitute part is active and available in tray packaging, whereas the main part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The FX2C2-52P-1.27DSA(71) is the direct substitute for the obsolete FX2C2-52P-1.27DSA. Both parts share identical electrical and mechanical specifications across all critical parameters including position count, pitch, connector type, mounting configuration, and termination method.

The substitute part offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• RoHS compliance status differs from the main part; the substitute is RoHS compliant
• Specified contact finish thickness (7.87µin / 0.200µm) provides documented plating specifications
• Tray packaging is specified for the substitute part

Selection of the substitute part is appropriate for applications requiring the same electrical and mechanical interface as the original part, with the additional benefit of current product status and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Are FX2C2-52P-1.27DSA and FX2C2-52P-1.27DSA(71) electrically and mechanically interchangeable?

A: Yes. Both parts are identical in electrical and mechanical specifications. They share the same 52-position configuration, 1.27mm pitch, through-hole solder termination, and board-to-board application type.

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

A: The "(71)" designation indicates a packaging variant. The substitute part is supplied in tray packaging, whereas the main part packaging is not specified.

Q: Does the RoHS compliance difference affect substitution compatibility?

A: RoHS compliance is a regulatory and supply chain consideration rather than an electrical or mechanical parameter. The substitute part's RoHS compliance status does not affect functional compatibility with the original part.

Q: Is the contact finish thickness specification critical for substitution?

A: The contact finish thickness (7.87µin / 0.200µm) is specified for the substitute part but not for the main part. Both parts use gold contact finish. The specified thickness for the substitute part provides documented plating specifications for quality assurance purposes.

Q: Why is the main part classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on production discontinuation. The substitute part FX2C2-52P-1.27DSA(71) remains active and is the recommended source for continued component procurement.

Q: Can the substitute part be used in existing designs originally specified for the main part?

A: Yes. The substitute part maintains full compatibility with designs specified for the original part due to identical electrical, mechanical, and dimensional specifications.
