Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX8-90P-SV(21) is determined by the following critical parameters:

• Connector Type & Configuration: Header with outer shroud contacts, 90 positions, 2 rows
• Electrical Interface: 0.024" (0.60mm) pitch contact spacing
• Mounting Technology: Surface mount with board guide
• Contact Material: Gold plating for signal integrity and corrosion resistance
• Manufacturer Consistency: Hirose Electric Co Ltd FunctionMax™ FX8 series

The FX8-90P-SV1(91) qualifies as a direct substitute based on identical electrical and mechanical interface parameters. Both parts maintain the same connector topology, position count, pitch, row configuration, mounting method, and contact finish. Differences in mated stacking height and height above board represent design iterations within the same functional family and do not preclude substitution in applications where the connector footprint and interface requirements are met.

Parameter Comparison

Engineering Selection Recommendations

The FX8-90P-SV1(91) is the primary substitute for the obsolete FX8-90P-SV(21). Selection between these parts should be based on the following engineering criteria:

Product Status & Availability: The FX8-90P-SV(21) is obsolete with limited remaining inventory (891 pcs). The FX8-90P-SV1(91) is active with higher inventory availability (970 pcs), ensuring long-term supply chain support for new designs and production continuity.

Regulatory Compliance: The FX8-90P-SV1(91) is RoHS compliant, whereas the FX8-90P-SV(21) is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, the FX8-90P-SV1(91) is the required selection.

Physical Dimensions: The FX8-90P-SV1(91) has a mated stacking height of 4mm and height above board of 0.152" (3.85mm), compared to 3mm and 0.112" (2.85mm) respectively for the FX8-90P-SV(21). Design layouts must accommodate these dimensional differences to ensure proper board clearance and mating interface alignment.

Electrical & Mechanical Compatibility: Both parts maintain identical connector topology, pitch, position count, and contact finish. The electrical interface and mechanical mounting footprint are fully compatible.

Frequently Asked Questions (FAQ)

Q: Can the FX8-90P-SV1(91) be used as a direct replacement for the FX8-90P-SV(21)?

A: Yes, the FX8-90P-SV1(91) is a direct electrical and mechanical substitute. Both connectors share identical position count (90), pitch (0.024"/0.60mm), row configuration (2), connector type (header with outer shroud contacts), mounting method (surface mount), and contact finish (gold). The primary differences are product status (active vs. obsolete), RoHS compliance, and physical height dimensions.

Q: What are the key dimensional differences between these parts?

A: The FX8-90P-SV1(91) has a mated stacking height of 4mm and height above board of 0.152" (3.85mm), while the FX8-90P-SV(21) measures 3mm and 0.112" (2.85mm) respectively. These differences must be evaluated against PCB layout constraints, enclosure clearances, and mating interface requirements.

Q: Is the FX8-90P-SV1(91) RoHS compliant?

A: Yes, the FX8-90P-SV1(91) is RoHS compliant. The FX8-90P-SV(21) is RoHS non-compliant. For applications requiring RoHS compliance, the FX8-90P-SV1(91) is the appropriate selection.

Q: What packaging is available for the FX8-90P-SV1(91)?

A: The FX8-90P-SV1(91) is supplied in tube packaging. The FX8-90P-SV(21) packaging information is not specified.

Q: Are there any electrical performance differences between these connectors?

A: No electrical performance differences exist. Both parts maintain identical contact pitch, material composition (gold plating), and connector topology. Electrical characteristics are equivalent.

Q: What is the current inventory status?

A: The FX8-90P-SV(21) has 891 pcs in stock (obsolete status). The FX8-90P-SV1(91) has 970 pcs in stock (active status), providing greater availability for ongoing production requirements.
