Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX8-140P-SV(71) is determined by strict equivalence across the following critical parameters:

• Number of Positions: 140 (electrical interface requirement)
• Pitch: 0.024" (0.60mm) (mechanical compatibility requirement)
• Number of Rows: 2 (form factor requirement)
• Connector Type: Header, Outer Shroud Contacts (functional requirement)
• Mounting Type: Surface Mount (assembly process requirement)
• Contact Finish: Gold (electrical performance requirement)
• Mated Stacking Height: 3mm (mechanical interface requirement)
• Height Above Board: 0.112" (2.85mm) (PCB clearance requirement)
• Features: Board Guide (mechanical alignment requirement)
• Series: FunctionMax™ FX8 (design family requirement)

Parts meeting all these parameters are classified as parametric equivalents and may be substituted without design modification or re-qualification.

Parameter Comparison

Engineering Selection Recommendations

The FX8-140P-SV(91) is a parametric equivalent to the FX8-140P-SV(71) and qualifies as a direct substitute. Both parts are active products from Hirose Electric Co Ltd within the FunctionMax™ FX8 series and share identical electrical and mechanical specifications across all critical parameters.

The FX8-140P-SV(91) carries ROHS3 compliance certification, which represents an enhanced regulatory status compared to the RoHS compliance of the FX8-140P-SV(71). Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating and are suitable for standard manufacturing and storage conditions.

Selection between these parts should be based on procurement availability, lead time, and inventory position. The FX8-140P-SV(91) currently maintains higher inventory availability (2983 pcs) compared to the FX8-140P-SV(71) (760 pcs), which may influence sourcing decisions for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can the FX8-140P-SV(91) be used as a direct replacement for the FX8-140P-SV(71) without PCB redesign?

A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications. No PCB redesign, footprint modification, or re-qualification is required for substitution.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents the current regulatory standard for RoHS compliance. Both certifications indicate compliance with hazardous substance restrictions. The FX8-140P-SV(91) carries the more current ROHS3 designation.

Q: Are the pitch and position count identical between these parts?

A: Yes. Both parts feature 140 positions arranged in 2 rows with a 0.024" (0.60mm) pitch. Electrical interface and mechanical compatibility are identical.

Q: Does the MSL rating differ between these parts?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or manufacturing processes.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. Identical mounting type (surface mount), stacking height (3mm), and board height (0.112" / 2.85mm) ensure mechanical and electrical interchangeability in existing PCB designs and assembly processes.
