Key Parameters

Substitute Part Grouping Explanation

Substitution of the FX8C-100P-SV(21) is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header with outer shroud contacts, 100 positions, 2-row arrangement
• Electrical Interface: 0.024" (0.60mm) pitch contact spacing
• Physical Dimensions: 0.175" (4.45mm) height above board, compatible mated stacking heights (5mm, 10mm)
• Surface Mount Compatibility: Identical mounting type and board guide features
• Contact Material: Gold finish for equivalent electrical performance and reliability
• Environmental Classification: MSL 1 rating for unlimited moisture exposure tolerance

The FX8C-100P-SV(91) meets all these criteria as a direct functional equivalent within the same FunctionMax™ FX8C series.

Parameter Comparison

Engineering Selection Recommendations

The FX8C-100P-SV(91) is the direct functional equivalent for the obsolete FX8C-100P-SV(21). Both components share identical electrical and mechanical specifications within the FunctionMax™ FX8C series. The primary distinction is product lifecycle status: FX8C-100P-SV(91) is active and carries ROHS3 compliance certification, whereas FX8C-100P-SV(21) is obsolete and RoHS non-compliant.

For new designs or component replenishment, FX8C-100P-SV(91) is the appropriate selection. The packaging difference (tube for the substitute) does not affect functional compatibility or board-level performance. Both parts maintain identical contact pitch, position count, mounting footprint, and environmental ratings.

Frequently Asked Questions (FAQ)

Q: Are FX8C-100P-SV(21) and FX8C-100P-SV(91) electrically interchangeable?

A: Yes. Both components feature identical contact pitch (0.024"), position count (100), row configuration (2), and gold contact finish. They are electrically equivalent for all signal and power distribution applications.

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

A: The suffix designation (21 vs. 91) indicates packaging and compliance generation. FX8C-100P-SV(91) is the current production variant with ROHS3 compliance and tube packaging, while FX8C-100P-SV(21) is obsolete.

Q: Can I use FX8C-100P-SV(91) as a direct replacement in existing assemblies?

A: Yes. The mechanical footprint, board guide features, height above board (0.175"), and mated stacking heights (5mm, 10mm) are identical. No PCB redesign is required.

Q: Does the tube packaging of FX8C-100P-SV(91) affect compatibility?

A: No. Packaging format does not affect component functionality or board-level performance. Tube packaging is standard for surface mount connectors and does not impact electrical or mechanical characteristics.

Q: Are there compliance advantages to using FX8C-100P-SV(91)?

A: Yes. FX8C-100P-SV(91) carries ROHS3 compliance certification, whereas FX8C-100P-SV(21) is RoHS non-compliant. For applications subject to RoHS regulations, FX8C-100P-SV(91) is the required selection.
