Parameter Comparison

Engineering Selection Recommendations

Both FX8C-120P-SV(91) and FX8C-120P-SV(71) are direct parametric equivalents to the FX8C-120P-SV(21), with identical electrical and mechanical specifications.

FX8C-120P-SV(91) is a direct manufacturer substitute with active product status and ROHS3 compliance. This part is recommended for new designs and applications requiring current RoHS certification. Inventory availability is 2100 units, packaged in tube format.

FX8C-120P-SV(71) is a parametric equivalent with active product status and RoHS compliance. This part is suitable for applications requiring RoHS-compliant components. Inventory availability is 686 units, packaged in tube format.

The FX8C-120P-SV(21) is obsolete and RoHS non-compliant. For ongoing production or maintenance applications, either active substitute part provides equivalent functionality with improved compliance status.

Frequently Asked Questions (FAQ)

Q: Can FX8C-120P-SV(91) or FX8C-120P-SV(71) be used as direct replacements for FX8C-120P-SV(21)?

A: Yes. Both parts are parametric equivalents with identical position count (120), pitch (0.60mm), row configuration (2), connector type, mounting method, contact finish, and physical dimensions. They are electrically and mechanically interchangeable.

Q: What is the difference between FX8C-120P-SV(91) and FX8C-120P-SV(71)?

A: Both parts are parametrically identical. The primary differences are product status (both active), RoHS compliance level (ROHS3 vs. RoHS), and current inventory levels (2100 vs. 686 units). Both are packaged in tube format.

Q: Why is the FX8C-120P-SV(21) listed as obsolete?

A: Product status reflects manufacturer lifecycle designation. The FX8C-120P-SV(21) has been superseded by active variants within the same FunctionMax™ FX8C series.

Q: Are there any packaging differences between these parts?

A: The FX8C-120P-SV(21) has unspecified packaging. Both FX8C-120P-SV(91) and FX8C-120P-SV(71) are supplied in tube packaging.

Q: Which substitute part should be selected for new designs?

A: Selection between FX8C-120P-SV(91) and FX8C-120P-SV(71) depends on specific RoHS compliance requirements. FX8C-120P-SV(91) carries ROHS3 certification and is recommended where the highest RoHS compliance level is required.
