Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX8-140P-SV(21) is determined by strict equivalence across the following parameters:

• Identical position count (140 positions)
• Identical pitch specification (0.024" / 0.60mm)
• Identical row configuration (2 rows)
• Identical connector type (Header, Outer Shroud Contacts)
• Identical mounting technology (Surface Mount)
• Identical contact finish material (Gold)
• Identical mechanical dimensions (3mm stacking height, 0.112" height above board)
• Identical board guide feature
• Same base product series (FX8)

Two substitute parts meet these criteria: FX8-140P-SV(91) and FX8-140P-SV(71). Both maintain full parametric equivalence to the main part across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both FX8-140P-SV(91) and FX8-140P-SV(71) are direct parametric equivalents to the FX8-140P-SV(21) and are suitable for substitution based on electrical and mechanical compatibility.

The primary differentiators between substitute options are product status and regulatory compliance:

FX8-140P-SV(91) carries active product status and ROHS3 compliance certification, indicating current manufacturing support and alignment with the most recent RoHS directive requirements.

FX8-140P-SV(71) carries active product status and RoHS compliance certification, indicating current manufacturing support and compliance with RoHS standards.

Both substitute parts are packaged in tube format. Selection between these options should be based on specific regulatory requirements applicable to the end application and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can FX8-140P-SV(91) or FX8-140P-SV(71) be used as direct replacements for FX8-140P-SV(21)?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, connector type, mounting technology, contact finish, and dimensional characteristics. They are parametrically equivalent and suitable for direct substitution.

Q: What is the difference between FX8-140P-SV(91) and FX8-140P-SV(71)?

A: Both parts are parametrically identical. The primary differences are RoHS certification level (ROHS3 for FX8-140P-SV(91) versus RoHS for FX8-140P-SV(71)) and potential supply availability. Selection should be based on regulatory requirements for your application.

Q: Why is the original FX8-140P-SV(21) marked as obsolete?

A: The FX8-140P-SV(21) carries obsolete product status, indicating it is no longer in active production. The substitute parts FX8-140P-SV(91) and FX8-140P-SV(71) are active products that provide equivalent functionality and are recommended for new designs and ongoing supply requirements.

Q: Are there any packaging differences between the main part and substitutes?

A: The FX8-140P-SV(21) packaging specification is not provided in the technical data. Both substitute parts are supplied in tube packaging. Confirm packaging requirements for your assembly process before finalizing part selection.

Q: Do all three parts share the same board guide feature?

A: Yes. The board guide feature is present on the FX8-140P-SV(21), FX8-140P-SV(91), and FX8-140P-SV(71), ensuring consistent mechanical alignment and assembly compatibility across all three part numbers.
