Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX8-40P-SV(21) is determined by strict equivalence across the following parameters:

• Connector type and contact configuration (Header, Outer Shroud Contacts)
• Electrical specifications (40 positions, 0.60mm pitch, 2-row configuration)
• Mechanical dimensions (3mm mated stacking height, 0.112" height above board)
• Contact material and finish (Gold plating)
• Mounting technology (Surface Mount with Board Guide feature)
• Environmental classification (MSL 1)

The FX8-40P-SV(91) and FX8-40P-SV(71) meet all these criteria and are classified as direct manufacturer equivalents within the FunctionMax™ FX8 series. Both parts maintain identical electrical and mechanical specifications while differing only in packaging configuration and compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both FX8-40P-SV(91) and FX8-40P-SV(71) are functionally equivalent to the obsolete FX8-40P-SV(21) and are suitable for direct substitution in new designs and production environments.

For applications subject to RoHS compliance requirements, both substitute parts satisfy current regulatory standards. The FX8-40P-SV(91) carries ROHS3 compliance certification, while the FX8-40P-SV(71) carries RoHS compliance certification. The original FX8-40P-SV(21) is RoHS non-compliant and should be replaced in regulated applications.

Both substitute parts maintain identical electrical performance, mechanical fit, and environmental ratings. Selection between FX8-40P-SV(91) and FX8-40P-SV(71) may be determined by packaging requirements, inventory availability, and supply chain logistics, as both are supplied in tube packaging and carry active product status.

Frequently Asked Questions (FAQ)

Q: Can FX8-40P-SV(91) or FX8-40P-SV(71) be used as direct replacements for FX8-40P-SV(21)?

A: Yes. Both parts are direct manufacturer equivalents with identical electrical specifications, mechanical dimensions, contact configuration, and mounting characteristics. No design modifications are required for substitution.

Q: What is the difference between FX8-40P-SV(91) and FX8-40P-SV(71)?

A: The parts are electrically and mechanically identical. The primary differences are RoHS compliance status (ROHS3 for FX8-40P-SV(91) versus RoHS for FX8-40P-SV(71)) and current inventory levels. Both are supplied in tube packaging.

Q: Why is the FX8-40P-SV(21) marked as obsolete?

A: The FX8-40P-SV(21) has been superseded by active production variants within the FunctionMax™ FX8 series. The substitute parts FX8-40P-SV(91) and FX8-40P-SV(71) represent the current manufacturing offerings with improved compliance certifications.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. All three parts share identical pitch spacing (0.60mm), row configuration (2 rows), position count (40), mounting type (Surface Mount), and mechanical envelope. PCB footprints and mating connector specifications remain unchanged.

Q: What packaging formats are available for the substitute parts?

A: Both FX8-40P-SV(91) and FX8-40P-SV(71) are supplied in tube packaging, suitable for automated assembly processes and manual component handling.

Q: Do the substitute parts meet current environmental and regulatory standards?

A: Yes. Both FX8-40P-SV(91) and FX8-40P-SV(71) are RoHS compliant, REACH unaffected, and classified under ECCN EAR99. The original FX8-40P-SV(21) is RoHS non-compliant and should be replaced in regulated applications.
