Substitute Part Grouping Explanation

Substitution eligibility for the FX8-80P-SV(71) is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header with outer shroud contacts, 80 positions arranged in 2 rows
• Electrical Interface: 0.024" (0.60mm) pitch contact spacing
• Physical Dimensions: 3mm mated stacking height, 0.112" (2.85mm) height above board
• Mounting Technology: Surface mount with board guide feature
• Contact Material: Gold finish for signal integrity and corrosion resistance
• Compliance & Environmental: RoHS compliance and MSL 1 rating for unlimited moisture exposure

The identified substitute part FX8-80P-SV(91) maintains full parametric equivalence across all critical dimensions, electrical characteristics, and environmental ratings, ensuring direct functional interchangeability in circuit board assembly.

Parameter Comparison

Engineering Selection Recommendations

Both the FX8-80P-SV(71) and FX8-80P-SV(91) are active production parts with full regulatory compliance. The FX8-80P-SV(91) carries ROHS3 compliance designation and REACH unaffected status, providing additional environmental documentation for applications requiring enhanced regulatory traceability. Selection between these parts should be based on inventory availability, procurement lead times, and specific regulatory documentation requirements for the end application. Both parts are functionally and mechanically interchangeable with identical electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are FX8-80P-SV(71) and FX8-80P-SV(91) mechanically interchangeable?

A: Yes. Both parts share identical physical dimensions, mounting footprint, and board guide features. They can be used interchangeably in surface mount assembly without PCB redesign.

Q: What is the difference between the two part numbers?

A: The primary difference is the regulatory compliance designation. FX8-80P-SV(91) carries ROHS3 compliance and REACH unaffected status, while FX8-80P-SV(71) is RoHS compliant. Both meet the same environmental and electrical performance requirements.

Q: Can these connectors be used in high-density applications?

A: Yes. The 0.024" (0.60mm) pitch and 80-position configuration support high-density interconnect requirements. The board guide feature ensures proper alignment during assembly.

Q: What is the significance of MSL 1 rating?

A: MSL 1 indicates unlimited moisture sensitivity, meaning the connector can be stored and handled without moisture-related degradation concerns. No special dry-pack storage or baking procedures are required.

Q: Are the contact finishes identical?

A: Yes. Both parts feature gold contact finish, providing equivalent signal integrity, corrosion resistance, and electrical performance.

Q: What is the mated stacking height used for?

A: The 3mm mated stacking height defines the vertical distance between the header and its mating connector when fully engaged. This is critical for PCB layout and enclosure clearance planning.
