Substitute Part Grouping Explanation

Substitution of the FX10B-100S/10-SV(21) is determined by strict equivalence across the following critical parameters:

• Connector Type & Series: Receptacle, Center Strip Contacts within the FunctionMax™ FX10 series
• Electrical Configuration: 100 positions, 2 rows, 0.020" (0.50mm) pitch
• Mounting & Physical Dimensions: Surface mount with 0.126" (3.20mm) height above board and compatible mated stacking heights (4mm, 5mm)
• Contact Properties: Gold finish at 4.00µin (0.100µm) thickness
• Mechanical Features: Ground plate and solder retention
• Environmental Rating: MSL 1 (Unlimited moisture sensitivity)

The substitute part FX10B-100S/10-SV(91) maintains identical electrical and mechanical specifications while differing in packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

For Legacy System Support (Obsolete Design Retention): The FX10B-100S/10-SV(21) remains the original specification. However, given its obsolete status, long-term availability is not assured. Existing inventory should be evaluated for remaining lifecycle requirements.

For New Designs or Redesign Initiatives: The FX10B-100S/10-SV(91) is the recommended substitute. This part maintains complete electrical and mechanical compatibility while offering the following advantages:

• Active product status ensures ongoing manufacturer support and availability
• RoHS compliance aligns with current regulatory requirements and supply chain standards
• Tape & Reel packaging supports automated assembly processes and reduces handling costs
• Identical connector specifications guarantee direct form, fit, and function compatibility

Both parts share identical ECCN and HTSUS classifications, ensuring equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Are FX10B-100S/10-SV(21) and FX10B-100S/10-SV(91) electrically interchangeable? A: Yes. Both parts are 100-position receptacles with identical pitch (0.020"), row configuration (2 rows), contact finish (gold at 4.00µin), and mating interface specifications. They are electrically and mechanically equivalent.

Q: What is the difference between the two part numbers? A: The primary differences are packaging format and product status. The FX10B-100S/10-SV(21) is supplied in bulk packaging and is obsolete. The FX10B-100S/10-SV(91) is supplied in Tape & Reel format and maintains active status with RoHS compliance.

Q: Can I use FX10B-100S/10-SV(91) as a direct replacement in existing assemblies? A: Yes, provided your assembly process supports Tape & Reel packaging. The connector itself is dimensionally and functionally identical, with no PCB layout or mating interface modifications required.

Q: Does the RoHS compliance difference affect compatibility? A: No. RoHS compliance is a material composition specification that does not affect electrical or mechanical performance. The FX10B-100S/10-SV(91) is RoHS compliant, making it suitable for applications with regulatory requirements.

Q: Are there any height or footprint differences? A: No. Both parts have identical height above board (0.126" / 3.20mm) and mated stacking heights (4mm, 5mm). PCB footprints are identical.

Q: What is the MSL rating, and does it affect storage? A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity. Standard storage conditions apply without special desiccant or humidity control requirements.
