Parameter Comparison

Engineering Selection Recommendations

The FX8C-140S-SV(68) is the direct substitute for the obsolete FX8C-140S-SV(91). Both connectors maintain identical electrical and mechanical specifications, including position count, pitch, mounting configuration, and contact characteristics. The primary distinction is product status: FX8C-140S-SV(68) is an active product with documented RoHS3 compliance and REACH unaffected status, providing superior supply chain continuity and regulatory documentation for new designs or production transitions.

The height above board differential of 0.001" (0.01mm) between the two variants is within standard manufacturing tolerance and does not affect functional compatibility or PCB layout requirements.

Frequently Asked Questions (FAQ)

Q: Can FX8C-140S-SV(68) be used as a direct replacement for FX8C-140S-SV(91)?

A: Yes. Both connectors share identical position count (140), pitch (0.024"), mounting type (surface mount), contact finish (gold), and board guide features. The FX8C-140S-SV(68) is an active product variant with current compliance documentation.

Q: What is the significance of the part number suffix difference between (91) and (68)?

A: The suffix designates packaging and manufacturing batch variants within the same FunctionMax™ FX8C series. Both variants maintain identical connector specifications and are functionally interchangeable.

Q: Are there any PCB layout considerations when transitioning from FX8C-140S-SV(91) to FX8C-140S-SV(68)?

A: No. The height above board difference of 0.001" (0.01mm) is negligible and falls within standard PCB design tolerances. Footprint and mounting requirements remain unchanged.

Q: What compliance certifications apply to the substitute part?

A: FX8C-140S-SV(68) is RoHS3 compliant and REACH unaffected, providing regulatory alignment for current manufacturing standards.

Q: Is packaging different between the two variants?

A: FX8C-140S-SV(91) packaging is not specified in available documentation. FX8C-140S-SV(68) is supplied in tube packaging. Confirm packaging requirements with your procurement process.
