Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX8C-100S-SV(91) is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Receptacle, Center Strip Contacts)
• Position count and electrical interface (100 positions)
• Contact pitch and row configuration (0.024" / 0.60mm, 2 rows)
• Mounting technology (Surface Mount)
• Contact material and finish (Gold)
• Mechanical compatibility (Board Guide feature, mated stacking heights)
• Environmental classification (MSL 1)
• Regulatory compliance (ECCN, HTSUS)

The FX8C-100S-SV(68) meets all substitution criteria as a direct equivalent within the FunctionMax™ FX8C series, with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The FX8C-100S-SV(68) is the direct substitute for the obsolete FX8C-100S-SV(91). Both components share identical electrical and mechanical specifications within the FunctionMax™ FX8C series. The primary distinction is product status: FX8C-100S-SV(91) is obsolete, while FX8C-100S-SV(68) is active with significantly higher inventory availability (9500 units versus 827 units).

The FX8C-100S-SV(68) carries ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment for new designs and long-term supply chain stability. Height above board measurements are functionally equivalent (0.155" versus 0.156"), with negligible mechanical variance. Packaging is supplied in tube format for the active substitute.

Frequently Asked Questions (FAQ)

Q: Can FX8C-100S-SV(68) be used as a direct replacement for FX8C-100S-SV(91)?

A: Yes. Both components are 100-position receptacles with identical pitch (0.024" / 0.60mm), row configuration (2 rows), mounting type (Surface Mount), contact finish (Gold), and mechanical features (Board Guide). Height above board measurements differ by 0.01" (0.01mm), which is within standard manufacturing tolerance and does not affect functional compatibility.

Q: What is the significance of the product status difference?

A: FX8C-100S-SV(91) is classified as obsolete, indicating discontinued manufacturing and limited future availability. FX8C-100S-SV(68) is active, ensuring ongoing production, supply chain support, and compliance with current regulatory standards. For new designs, FX8C-100S-SV(68) is the recommended selection.

Q: Are there packaging differences between these parts?

A: FX8C-100S-SV(68) is supplied in tube packaging. The original part's packaging specification is not provided in available documentation. Tube packaging is standard for surface mount connectors and supports automated assembly processes.

Q: Do compliance certifications affect substitution eligibility?

A: FX8C-100S-SV(68) carries ROHS3 compliance and REACH unaffected status. These certifications enhance regulatory alignment for applications subject to environmental and hazardous substance restrictions. Both components share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What are the mated stacking height options?

A: Both components support identical mated stacking heights: 5mm, 6mm, 7mm, 9mm, and 11mm. Selection depends on application-specific interconnect requirements and PCB layout constraints.
