FX6-20S-0.8SV Equivalent & Substitute Parts

Part Overview

The FX6-20S-0.8SV is a 20-position rectangular connector receptacle manufactured by Hirose Electric Co Ltd, designed for surface mount applications with center strip contacts and gold plating. This connector is classified as obsolete, making equivalent and substitute parts necessary for ongoing production support, maintenance, and new design implementations where inventory of the original part is limited or unavailable.

Substitute Part Grouping Explanation

Substitution for the FX6-20S-0.8SV is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with center strip contacts
• Number of positions: 20
• Pitch: 0.031" (0.80mm)
• Number of rows: 2
• Mounting type: Surface Mount
• Contact finish: Gold
• Mated stacking heights: 5mm, 6mm, 7mm
• Height above board: 0.157" (4.00mm)
• Board guide feature: Present

The substitute parts FX6-20S-0.8SV(71) and FX6-20S-0.8SV(91) maintain identical electrical and mechanical specifications to the main part number. These variants differ only in packaging format and product status, with both active alternatives available from the same manufacturer within the FX6 series.

Parameter Comparison

Engineering Selection Recommendations

Both FX6-20S-0.8SV(71) and FX6-20S-0.8SV(91) are direct functional equivalents to the obsolete FX6-20S-0.8SV. Selection between these active alternatives should be based on the following factors:

FX6-20S-0.8SV(71) carries ROHS3 compliance certification, making it suitable for applications requiring the highest level of regulatory adherence in restricted substance management.

FX6-20S-0.8SV(91) carries RoHS compliance certification and represents an alternative for applications where ROHS3 certification is not explicitly required.

Both parts maintain identical electrical and mechanical specifications, including connector type, position count, pitch, mounting configuration, contact finish, and board guide features. The original FX6-20S-0.8SV is RoHS non-compliant; therefore, either substitute part provides improved regulatory compliance for new designs or production transitions.

Frequently Asked Questions (FAQ)

Q: Are FX6-20S-0.8SV(71) and FX6-20S-0.8SV(91) electrically and mechanically interchangeable with the original FX6-20S-0.8SV?

A: Yes. Both substitute parts maintain identical specifications across all critical parameters: 20-position configuration, 0.031" (0.80mm) pitch, 2-row layout, surface mount design, gold contact finish, and board guide feature. They are direct functional equivalents.

Q: What is the primary difference between the substitute parts?

A: The primary differences are product status and regulatory compliance. FX6-20S-0.8SV(71) is ROHS3 compliant, while FX6-20S-0.8SV(91) is RoHS compliant. Both are active products supplied in tube packaging, whereas the original part is obsolete.

Q: Can I use these substitutes in existing designs without PCB modifications?

A: Yes. The substitute parts maintain identical mounting type, height above board (0.157" / 4.00mm), and mated stacking heights (5mm, 6mm, 7mm). No PCB layout or assembly process changes are required.

Q: Which substitute should I select for new product designs?

A: Selection depends on regulatory requirements. For applications requiring ROHS3 compliance, use FX6-20S-0.8SV(71). For applications requiring standard RoHS compliance, either part is acceptable. Both are active products with established supply chains.

Q: Are there any MSL or moisture sensitivity differences between the parts?

A: No. All three part numbers carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
