Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX6-40S-0.8SV2(91) is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Receptacle, Center Strip Contacts)
• Number of positions (40)
• Pitch specification (0.031" / 0.80mm)
• Number of rows (2)
• Mounting technology (Surface Mount)
• Contact finish material (Gold)
• Height above board (0.236" / 6.00mm)
• Mated stacking height range (7mm, 8mm, 9mm)
• Board guide feature presence

The FX6-40S-0.8SV2(71) meets all these criteria and is classified as a parametric equivalent. Substitution between these parts does not require design modification or re-qualification when all electrical and mechanical parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

Both the FX6-40S-0.8SV2(91) and FX6-40S-0.8SV2(71) are active production parts from Hirose Electric Co Ltd and are suitable for direct substitution in applications requiring 40-position rectangular connectors with 0.80mm pitch and surface mount configuration.

The FX6-40S-0.8SV2(71) carries ROHS3 compliance status, which represents an enhanced regulatory position compared to the standard RoHS Compliant designation of the FX6-40S-0.8SV2(91). Both parts maintain MSL 1 rating, indicating unlimited shelf life under standard storage conditions.

Selection between these parts may be driven by inventory availability, supply chain lead times, or specific regulatory requirements of the end application. The FX6-40S-0.8SV2(71) currently maintains higher inventory levels at 1995 units compared to 634 units for the FX6-40S-0.8SV2(91).

Frequently Asked Questions (FAQ)

Q: Can FX6-40S-0.8SV2(71) be used as a direct replacement for FX6-40S-0.8SV2(91)?

A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications across all critical dimensions, contact configuration, pitch, and mounting characteristics. No design modification is required.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant designations?

A: ROHS3 Compliant represents compliance with the most current RoHS directive requirements. Both designations indicate the parts meet hazardous substance restrictions; ROHS3 reflects the latest regulatory standard. Both parts are suitable for applications with RoHS requirements.

Q: Are the mated stacking heights interchangeable between these parts?

A: Yes. Both parts support identical mated stacking heights of 7mm, 8mm, and 9mm, ensuring mechanical compatibility in mating applications.

Q: What does MSL 1 (Unlimited) mean for storage and handling?

A: MSL 1 indicates the part has unlimited shelf life under standard storage conditions (typically 23°C, 50% relative humidity). No special moisture control or baking procedures are required prior to assembly.

Q: Are both parts suitable for surface mount assembly?

A: Yes. Both the FX6-40S-0.8SV2(91) and FX6-40S-0.8SV2(71) are designed for surface mount technology with identical board guide features and height above board specifications of 0.236" (6.00mm).
