Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FX11B-100S-SV(21) are identified based on strict equivalence across the following critical parameters:

• Manufacturer and series consistency (Hirose Electric Co Ltd, FX11 series)
• Electrical specifications: 100 positions, 0.020" (0.50mm) pitch, 2-row configuration
• Mechanical compatibility: Surface mount, identical height above board (0.083" / 2.10mm), matching mated stacking heights
• Contact specifications: Gold finish with 4.00µin (0.100µm) thickness
• Functional features: Solder retention capability
• Compliance: RoHS compliant, MSL 1 rating

The FX11B-100S-SV(22) meets all these criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the FX11B-100S-SV(21) and FX11B-100S-SV(22) are active production parts with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and supply chain requirements. The FX11B-100S-SV(22) currently maintains higher inventory levels (1914 pcs vs. 666 pcs), which may provide supply chain advantages for high-volume applications. Both parts carry full RoHS compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Are FX11B-100S-SV(21) and FX11B-100S-SV(22) electrically interchangeable?
