Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX8-120P-SV(21) is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header with outer shroud contacts, 120 positions, 2-row arrangement
• Electrical Interface: 0.024" (0.60mm) pitch contact spacing
• Physical Mounting: Surface mount technology with board guide feature
• Contact Material: Gold plating for signal integrity and corrosion resistance
• Mechanical Envelope: 3mm mated stacking height and 0.112" (2.85mm) height above board

The FX8-120P-SV(91) satisfies all these parameters while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The FX8-120P-SV(91) is the direct functional equivalent of the FX8-120P-SV(21). Both parts maintain identical electrical and mechanical specifications across all critical interface parameters.

The FX8-120P-SV(91) is recommended for new designs and ongoing procurement due to its active product status and ROHS3 compliance. For systems currently using the FX8-120P-SV(21), the FX8-120P-SV(91) provides a direct replacement path without design modification, as all mating dimensions, contact pitch, and mounting characteristics are preserved.

Frequently Asked Questions (FAQ)

Q: Are the FX8-120P-SV(21) and FX8-120P-SV(91) mechanically interchangeable?

A: Yes. Both parts share identical connector type, position count, pitch, row configuration, mounting method, and physical envelope dimensions. They are direct mechanical equivalents.

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

A: The primary differences are product status and regulatory compliance. The FX8-120P-SV(21) is obsolete and RoHS non-compliant, while the FX8-120P-SV(91) is active and ROHS3 compliant. All functional and mechanical parameters are identical.

Q: Can I use the FX8-120P-SV(91) as a drop-in replacement for the FX8-120P-SV(21)?

A: Yes. The FX8-120P-SV(91) is a direct substitute with no design changes required. Mating connectors, PCB footprints, and assembly processes remain unchanged.

Q: What does the packaging difference mean?

A: The FX8-120P-SV(21) is supplied in standard packaging, while the FX8-120P-SV(91) is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Are there any compliance considerations when switching to the FX8-120P-SV(91)?

A: The FX8-120P-SV(91) meets ROHS3 compliance requirements, making it suitable for applications subject to RoHS regulations. Both parts maintain REACH Unaffected status and identical moisture sensitivity levels.
