Parameter Comparison

Engineering Selection Recommendations

The FX2CA1-52P-1.27DSA(71) is the direct functional equivalent for applications currently utilizing the obsolete FX2CA1-52P-1.27DSA. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and drop-in replacement capability.

The substitute part offers two significant advantages:

• Product Status: Active production status ensures long-term availability and supply chain continuity
• Compliance: RoHS compliance aligns with modern regulatory requirements, whereas the original part remains non-compliant

Both parts maintain equivalent environmental ratings (MSL 1), export classifications (EAR99), and tariff codes (HTSUS 8536.69.4040). The contact finish thickness specification provided for the substitute part (7.87µin / 0.200µm) represents documented gold plating, supporting consistent electrical performance across both variants.

Frequently Asked Questions (FAQ)

Q: Are FX2CA1-52P-1.27DSA and FX2CA1-52P-1.27DSA(71) electrically interchangeable?

A: Yes. Both parts feature identical 52-position, 2-row configurations with 1.27 mm pitch, center strip contacts, and gold-finished terminations. Electrical performance and pin assignments are equivalent.

Q: What is the significance of the "(71)" designation in FX2CA1-52P-1.27DSA(71)?

A: The "(71)" suffix indicates a specific packaging variant (Tray) and production revision of the base FX2C series connector. This designation distinguishes the active production version from the obsolete original.

Q: Can the substitute part be used in new designs?

A: Yes. The FX2CA1-52P-1.27DSA(71) is classified as active product status and is RoHS compliant, making it suitable for new design implementations and long-term production support.

Q: Are there any mechanical differences between these parts?

A: No mechanical differences exist. Both parts are through-hole solder-terminated connectors with identical mounting specifications and physical dimensions.

Q: What is the impact of RoHS compliance differences?

A: The original part is RoHS non-compliant, while the substitute is RoHS compliant. For applications subject to RoHS regulations or customer requirements, the substitute part is the appropriate selection.

Q: How does packaging affect part selection?

A: The substitute part is supplied in Tray packaging, which is standard for production quantities. The original part's packaging specification is not documented. Tray packaging is suitable for automated assembly and standard manufacturing workflows.
