FX11LB-140P-SV(21) Equivalent & Substitute Parts

Part Overview

The FX11LB-140P-SV(21) is a 140-position rectangular connector header manufactured by Hirose Electric Co Ltd. This surface mount component features outer shroud contacts with gold plating and is designed for high-density interconnect applications requiring reliable solder retention. The part maintains Active product status with full RoHS compliance and unlimited moisture sensitivity rating (MSL 1), making it suitable for industrial and commercial applications where component availability and long-term supply assurance are critical.

Identifying equivalent and substitute parts is necessary when addressing supply chain constraints, inventory optimization, or when alternative packaging configurations meet identical electrical and mechanical requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the FX11LB-140P-SV(21) is determined by strict equivalence across the following critical parameters:

• Connector Type & Series: Header with outer shroud contacts from the FX11 series
• Electrical Configuration: 140 positions arranged in 2 rows at 0.020" (0.50mm) pitch
• Contact Specifications: Gold finish with 4.00µin (0.100µm) thickness
• Mechanical Compatibility: Surface mount mounting type with 0.064" (1.64mm) height above board and 2mm mated stacking height
• Functional Features: Solder retention capability
• Compliance & Reliability: RoHS compliance, MSL 1 rating, and Active product status

The substitute part FX11LB-140P-SV(22) maintains identical electrical and mechanical parameters across all critical dimensions and specifications. The difference between these part numbers reflects packaging configuration variation (Tape & Reel designation suffix) rather than functional or dimensional divergence.

Parameter Comparison

Engineering Selection Recommendations

Both FX11LB-140P-SV(21) and FX11LB-140P-SV(22) are functionally and mechanically equivalent components suitable for direct substitution in applications requiring 140-position rectangular connector headers with the specified electrical and mechanical characteristics.

Selection between these parts should be based on:

• Inventory Availability: FX11LB-140P-SV(22) currently maintains higher stock levels (1170 pcs) compared to FX11LB-140P-SV(21) (749 pcs), providing supply chain flexibility
• Packaging Configuration: Both parts are supplied in Tape & Reel (TR) packaging, appropriate for automated assembly processes
• Compliance Requirements: Both parts satisfy RoHS compliance and MSL 1 requirements for unrestricted storage and handling
• Product Lifecycle Status: Both parts maintain Active status, ensuring continued manufacturer support and availability

No functional or dimensional trade-offs exist between these alternatives. Selection may be driven by procurement lead times, cost considerations, or existing supply agreements with the manufacturer.

Frequently Asked Questions (FAQ)

Q: Can FX11LB-140P-SV(22) be used as a direct replacement for FX11LB-140P-SV(21) in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters including connector type, position count, pitch, contact finish, mounting configuration, and mechanical dimensions. No design modifications are required for substitution.

Q: What is the difference between the FX11LB-140P-SV(21) and FX11LB-140P-SV(22) part numbers?
