Key Parameters

Substitute Part Grouping Explanation

Substitution of the FX8C-100P-SV6(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: 0.427" (10.85mm) height above board, 11mm and 16mm mated stacking heights
• Contact Material: Gold plating for signal integrity and corrosion resistance
• Mounting Technology: Surface mount assembly compatibility
• Mechanical Features: Board guide alignment system

The substitute part FX8C-100P-SV6(91) maintains identical electrical and mechanical specifications while differing only in packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The FX8C-100P-SV6(91) is the direct functional equivalent of the FX8C-100P-SV6(21). Selection between these parts is determined by regulatory and procurement requirements:

FX8C-100P-SV6(91) is the recommended selection for new designs and ongoing production due to its active product status and ROHS3 compliance. This part satisfies modern environmental regulations and ensures long-term supply chain availability.

FX8C-100P-SV6(21) remains electrically and mechanically compatible for legacy system maintenance where RoHS non-compliance is acceptable and existing inventory is available.

Both parts share identical electrical performance, mechanical fit, and contact interface specifications. The choice between them depends on compliance requirements and supply chain strategy rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Can FX8C-100P-SV6(91) be used as a direct replacement for FX8C-100P-SV6(21)?

A: Yes. Both parts are identical in connector type, position count, pitch, mounting method, contact finish, and physical dimensions. They are mechanically and electrically interchangeable.

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

A: The primary differences are product lifecycle status and regulatory compliance. FX8C-100P-SV6(21) is obsolete and RoHS non-compliant, while FX8C-100P-SV6(91) is active and ROHS3 compliant. Packaging differs: FX8C-100P-SV6(91) is supplied in tube format.

Q: Are there any dimensional or electrical differences?

A: No. Both parts maintain identical specifications for pitch (0.024"/0.60mm), row configuration (2 rows, 100 positions), height above board (0.427"/10.85mm), mated stacking heights (11mm, 16mm), and gold contact finish.

Q: Which part should be specified for new designs?

A: FX8C-100P-SV6(91) should be specified for new designs due to active product status and ROHS3 compliance, ensuring regulatory alignment and supply continuity.

Q: Is the packaging difference significant for assembly?

A: Packaging format (tube for FX8C-100P-SV6(91)) affects handling and storage but does not impact component performance or assembly compatibility. Verify packaging compatibility with your assembly process requirements.
