Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX11LA-140S-SV(21) is determined by strict equivalence across the following critical parameters:

• Connector Position Count: 140 positions (non-negotiable for circuit compatibility)
• Pitch Specification: 0.020" (0.50mm) (determines PCB footprint and contact spacing)
• Number of Rows: 2 rows (defines physical layout and mating interface)
• Connector Type: Receptacle with center strip contacts (functional role in assembly)
• Mounting Technology: Surface Mount (assembly process compatibility)
• Contact Finish: Gold plating at 4.00µin thickness (electrical performance and corrosion resistance)
• Physical Dimensions: Mated stacking height 2mm, height above board 0.065" (1.65mm) (mechanical clearance requirements)
• Compliance Standards: RoHS compliance and MSL 1 rating (regulatory and environmental requirements)

The FX11LA-140S-SV(22) meets all substitution criteria as a parametric equivalent within the FX11 series.

Parameter Comparison

Engineering Selection Recommendations

Both FX11LA-140S-SV(21) and FX11LA-140S-SV(22) are Active product status components from Hirose Electric Co Ltd with full RoHS compliance certification. Both parts carry MSL 1 rating, indicating no moisture sensitivity restrictions for storage and handling. The connectors are functionally and mechanically interchangeable for all 140-position, 0.50mm pitch surface mount applications requiring gold-plated center strip contacts.

Selection between these two part numbers should be based on inventory availability and supply chain considerations. The FX11LA-140S-SV(22) currently maintains higher inventory levels (1721 pcs) compared to FX11LA-140S-SV(21) (816 pcs), which may influence procurement decisions for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can FX11LA-140S-SV(22) be used as a direct replacement for FX11LA-140S-SV(21)?

A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications across all critical parameters including position count, pitch, mounting type, contact finish, and physical dimensions. No circuit redesign or PCB layout modification is required.

Q: What determines if a connector is a valid substitute?

A: Substitution validity is determined by matching specifications in connector position count (140), pitch (0.50mm), number of rows (2), connector type (receptacle with center strip contacts), mounting technology (surface mount), contact finish (gold at 4.00µin), physical dimensions (2mm mated stacking height, 0.065" height above board), and compliance certifications (RoHS compliant, MSL 1).

Q: Are there any differences in the packaging format between these parts?

A: No. Both FX11LA-140S-SV(21) and FX11LA-140S-SV(22) are supplied in Tape & Reel (TR) packaging format, suitable for automated pick-and-place assembly processes.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 indicates Moisture Sensitivity Level 1, which means the component has unlimited shelf life under standard storage conditions (23°C, 50% relative humidity). No special moisture control or baking procedures are required prior to assembly.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both FX11LA-140S-SV(21) and FX11LA-140S-SV(22) are RoHS compliant, meeting restrictions on hazardous substances in electrical and electronic equipment.
