Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX8C-80P-SV(21) is determined by the following critical parameters:

• Number of Positions: 80 (exact match required)
• Pitch: 0.024" (0.60mm) (exact match required)
• Number of Rows: 2 (exact match required)
• Connector Type: Header, Outer Shroud Contacts (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Contact Finish: Gold (exact match required)
• Height Above Board: 0.175" (4.45mm) (exact match required)
• Mated Stacking Heights: 5mm, 10mm (exact match required)
• Series: FunctionMax™ FX8C (same series preferred)

The FX8C-80P-SV(91) qualifies as a direct substitute, maintaining identical electrical and mechanical specifications while offering improved product status and compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The FX8C-80P-SV(91) is the direct substitute for the FX8C-80P-SV(21). Both parts maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, row configuration, mounting type, and contact geometry.

The FX8C-80P-SV(91) offers three distinct advantages:

• Product Status: Active status ensures continued manufacturer support and availability
• RoHS Compliance: Meets RoHS requirements, whereas the FX8C-80P-SV(21) is non-compliant
• Packaging: Supplied in Tube packaging, providing standardized handling and inventory management

Selection of the FX8C-80P-SV(91) is appropriate for new designs, redesigns of legacy systems, or applications where regulatory compliance is required. The obsolete status of the FX8C-80P-SV(21) makes the active substitute the preferred choice for ongoing production.

Frequently Asked Questions (FAQ)

Q: Are the FX8C-80P-SV(21) and FX8C-80P-SV(91) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 80 positions, 0.60mm pitch, 2-row configuration, surface mount mounting type, and 0.175" (4.45mm) height above board. They are direct mechanical substitutes.

Q: What is the significance of the part number suffix (21) versus (91)?

A: The suffix indicates packaging and compliance variants within the same FunctionMax™ FX8C series. The FX8C-80P-SV(91) represents the active, RoHS-compliant variant supplied in Tube packaging.

Q: Can I use the FX8C-80P-SV(91) in place of the FX8C-80P-SV(21) without PCB redesign?

A: Yes. Identical electrical and mechanical parameters ensure direct substitution without PCB layout modifications or design changes.

Q: Why is the FX8C-80P-SV(21) marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The FX8C-80P-SV(91) represents the current production equivalent within the same series.

Q: Are there compliance differences between these parts?

A: Yes. The FX8C-80P-SV(91) is RoHS Compliant, while the FX8C-80P-SV(21) is RoHS non-compliant. Both maintain REACH Unaffected and EAR99 ECCN classifications.

Q: What packaging is supplied with each part?

A: The FX8C-80P-SV(21) packaging is unspecified in available documentation. The FX8C-80P-SV(91) is supplied in Tube packaging.
