Key Parameters

Substitute Part Grouping Explanation

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

• Connector Type & Series: Header with outer shroud contacts from the FunctionMax™ FX8 series
• Electrical Configuration: 140 positions arranged in 2 rows
• Pitch Specification: 0.024" (0.60mm) contact spacing
• Mounting Technology: Surface mount with board guide feature
• Contact Material: Gold plating for signal integrity and corrosion resistance
• Physical Dimensions: Mated stacking height of 3mm and height above board of 0.112" (2.85mm)

The FX8-140P-SV(91) variant meets all these criteria and qualifies as a direct substitute. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The FX8-140P-SV(91) is the direct substitute for the obsolete FX8-140P-SV. Both parts maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, mounting type, and physical dimensions.

The FX8-140P-SV(91) offers the additional advantage of active product status, ensuring continued availability and supply chain support. The variant also provides ROHS3 compliance, addressing regulatory requirements for new designs and manufacturing environments where RoHS compliance is mandated.

Selection between these parts should be based on regulatory requirements and supply chain considerations. The FX8-140P-SV(91) is the preferred choice for new applications and ongoing production where compliance certifications are required.

Frequently Asked Questions (FAQ)

Q: Are FX8-140P-SV and FX8-140P-SV(91) electrically and mechanically interchangeable?

A: Yes. Both parts are identical in electrical configuration (140 positions, 0.024" pitch), connector type (header with outer shroud contacts), mounting technology (surface mount), and physical dimensions (3mm mated stacking height, 0.112" height above board). They are direct substitutes.

Q: What does the (91) designation indicate?

A: The (91) suffix identifies a packaging variant. FX8-140P-SV(91) is supplied in tube packaging, whereas the original FX8-140P-SV packaging specification is not detailed in the available data.

Q: Why is the FX8-140P-SV classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The FX8-140P-SV(91) variant remains active and available, making it the recommended source for procurement.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance is a manufacturing and material specification, not a functional characteristic. Both parts perform identically in circuit operation. RoHS3 compliance of the FX8-140P-SV(91) is advantageous for applications subject to regulatory requirements or environmental standards.

Q: Can I use FX8-140P-SV(91) in existing designs specified for FX8-140P-SV?

A: Yes. The FX8-140P-SV(91) maintains full compatibility with designs specified for the FX8-140P-SV across all electrical, mechanical, and dimensional parameters. No design modifications are required.
