Key Parameters

Substitute Part Grouping Explanation

Substitution for the FX2BA-40PA-1.27DSA is determined by the following critical parameters:

• Number of Positions: 40 positions
• Pitch Specification: 1.27mm center-to-center spacing
• Connector Style: Center strip contacts
• Mounting Configuration: Through hole, vertical orientation
• Termination Method: Solder
• Connector Type: Plug

The substitute part FX2BA-40PA-1.27DSA(71) maintains identical electrical and mechanical specifications across all critical parameters. The designation suffix (71) indicates a packaging variation (Tray packaging) and represents an active production variant of the same base connector design within the FX2 series.

Parameter Comparison

Engineering Selection Recommendations

The FX2BA-40PA-1.27DSA(71) is the direct substitute for the obsolete FX2BA-40PA-1.27DSA. Both connectors share identical electrical and mechanical specifications, including position count, pitch, connector type, mounting method, and termination approach. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary distinction between the main part and substitute is regulatory compliance. The substitute part carries RoHS Compliant certification, whereas the original part is RoHS non-compliant. For applications subject to RoHS directives or requiring compliance documentation, the substitute part FX2BA-40PA-1.27DSA(71) is the appropriate selection. Both parts maintain identical moisture sensitivity classification and export control designations.

Frequently Asked Questions (FAQ)

Q: Can FX2BA-40PA-1.27DSA(71) be used as a direct replacement for FX2BA-40PA-1.27DSA?

A: Yes. The substitute part maintains identical position count (40), pitch (1.27mm), connector type (plug), mounting configuration (through hole), and termination method (solder). Electrical and mechanical compatibility is assured.

Q: What does the (71) designation indicate?

A: The (71) suffix denotes a packaging variation. The substitute part is supplied in Tray packaging, whereas the original part packaging specification was not provided. This affects procurement and handling procedures but does not alter connector functionality or electrical performance.

Q: Are there compliance differences between the two parts?

A: Yes. The substitute part FX2BA-40PA-1.27DSA(71) is RoHS Compliant, while the original FX2BA-40PA-1.27DSA is RoHS non-compliant. Both parts share identical moisture sensitivity levels and export control classifications.

Q: Is the substitute part currently available?

A: Yes. FX2BA-40PA-1.27DSA(71) is listed as Active product status with documented inventory availability, whereas the original part is obsolete.

Q: Are there any electrical performance differences?

A: No. Both parts are functionally equivalent. The substitute part specifies gold contact finish at 7.87µin (0.200µm) thickness, providing enhanced corrosion resistance and contact reliability compared to unspecified finish on the original part.
