Key Parameters

Substitute Part Grouping Explanation

Substitution of the FX8-90P-SV is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header with outer shroud contacts, 90 positions, 2-row arrangement
• Electrical Interface: 0.024" (0.60mm) pitch maintaining identical signal routing and mating compatibility
• Mounting Technology: Surface mount orientation and footprint compatibility
• Contact Material: Gold plating for equivalent electrical performance and corrosion resistance
• Mechanical Features: Board guide provision for alignment and stability
• Environmental Classification: MSL 1 rating for unlimited moisture exposure tolerance

The FX8-90P-SV1(91) maintains full equivalence across all these parameters while offering improved product status and compliance characteristics.

Engineering Selection Recommendations

The FX8-90P-SV1(91) is the direct active equivalent for the obsolete FX8-90P-SV. Selection of the substitute part is supported by:

• Product Status: The FX8-90P-SV1(91) maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete original part.
• Regulatory Compliance: The substitute achieves RoHS compliance, meeting current environmental and regulatory requirements for new designs and manufacturing processes.
• Functional Equivalence: All critical electrical and mechanical parameters remain identical, including connector configuration, pitch, contact finish, and MSL rating.
• Dimensional Consideration: The substitute exhibits increased mated stacking height (4mm vs. 3mm) and height above board (0.152" vs. 0.112"). Design verification is required to confirm accommodation within existing mechanical envelopes and clearance constraints.

Frequently Asked Questions (FAQ)

Q: Are the FX8-90P-SV and FX8-90P-SV1(91) electrically interchangeable?

A: Yes. Both parts maintain identical connector type, position count, pitch, row configuration, and contact finish. Electrical performance and signal integrity characteristics are equivalent.

Q: What is the primary difference between these parts?

A: The FX8-90P-SV1(91) is the active production equivalent with RoHS compliance. The original FX8-90P-SV is obsolete. Additionally, the substitute has increased stacking height (4mm vs. 3mm) and height above board (0.152" vs. 0.112").

Q: Will the FX8-90P-SV1(91) fit in existing PCB designs?

A: Electrical compatibility is confirmed. Mechanical fit requires verification of available clearance above the board and within the mated assembly. The increased height dimensions must be evaluated against design constraints.

Q: What packaging is available for the substitute part?

A: The FX8-90P-SV1(91) is supplied in tube packaging, compared to unspecified packaging for the original part.

Q: Is the MSL rating the same for both parts?

A: Yes. Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage and handling.

Q: Why should I transition from the FX8-90P-SV to the FX8-90P-SV1(91)?

A: The original part is obsolete and subject to supply discontinuation. The substitute ensures design continuity, regulatory compliance, and sustained component availability for current and future production.
