FX8C-60S-SV(91) Equivalent & Substitute Parts

Part Overview

The FX8C-60S-SV(91) is a 60-position rectangular connector receptacle manufactured by Hirose Electric Co Ltd, featuring center strip contacts with surface mount gold plating. This component is classified as obsolete, which necessitates identification of active equivalent parts to maintain design continuity and ensure supply chain availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FX8C-60S-SV(91) is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Receptacle, Center Strip Contacts)
• Position count and pitch (60 positions at 0.024" / 0.60mm)
• Row configuration (2 rows)
• Mounting technology (Surface Mount)
• Contact material and finish (Gold)
• Mechanical compatibility (Board Guide feature, mated stacking heights)
• Environmental classification (MSL 1)

The FX8C-60S-SV(68) meets all these criteria and is therefore a direct functional equivalent. The primary distinction is product status: FX8C-60S-SV(91) is obsolete, while FX8C-60S-SV(68) is active.

Parameter Comparison

Engineering Selection Recommendations

The FX8C-60S-SV(68) is the direct substitute for FX8C-60S-SV(91). Selection of the active part is justified by:

• Identical electrical and mechanical specifications across all critical parameters
• Active product status ensuring ongoing manufacturer support and supply availability
• RoHS3 compliance and REACH unaffected status of the substitute part
• Negligible height variance (0.01mm difference above board) within standard PCB assembly tolerances
• Equivalent MSL rating and export classification

Frequently Asked Questions (FAQ)

Q: Are FX8C-60S-SV(91) and FX8C-60S-SV(68) electrically interchangeable?

A: Yes. Both parts are 60-position receptacles with identical pitch, row configuration, contact finish, and mated stacking heights. They function identically in circuit applications.

Q: What is the significance of the height difference (0.156" vs 0.155")?

A: The 0.01mm variance is within standard PCB assembly tolerances and does not affect mechanical or electrical compatibility. Both parts accommodate the same mated stacking heights.

Q: Does the packaging difference affect compatibility?

A: No. FX8C-60S-SV(91) packaging is not specified; FX8C-60S-SV(68) is supplied in tube packaging. Packaging affects handling and storage only, not component function or performance.

Q: Why is FX8C-60S-SV(91) obsolete?

A: Product obsolescence is determined by the manufacturer. FX8C-60S-SV(68) is the active equivalent and should be used for all new designs and procurement.

Q: Are there compliance differences between the two parts?

A: FX8C-60S-SV(68) carries explicit RoHS3 compliance and REACH unaffected certifications. Both parts share identical ECCN and HTSUS classifications.
