SP8J5FRATB Equivalent & Substitute MOSFETs Reference

Part Overview

The SP8J5FRATB, manufactured by Rohm Semiconductor, is a dual P-Channel MOSFET array rated at 7A for surface mount applications in an 8-SOP (SOIC) package. It features logic level gate drive (4V), 28mΩ Rds(on) at 7A/10V, and is AEC-Q101 automotive qualified. The part is specified as Not For New Designs. Identifying substitute or equivalent MOSFETs is required to support ongoing designs and ensure supply continuity where the original part is not recommended for new projects.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection is strictly determined based on the following parameters: configuration (2 P-Channel Dual), mounting type (Surface Mount), package/case (8-SOIC or equivalent), current rating (Id), Rds(on) at specified Id/Vgs, gate threshold voltage (Vgs(th)), temperature rating, compliance (RoHS3, REACH), and qualification (if specified such as AEC-Q101). Only parts matching or closely aligning with these parameters have been included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

SP8J5FRATB is Not For New Designs; therefore, continued availability is not guaranteed. Eligible substitutes, DMP3028LSD-13 and FDS6975, match the required package, dual P-Channel configuration, surface mount format, and qualification parameters. All listed parts are ROHS3 compliant, REACH unaffected, and have an MSL of 1 (Unlimited). For applications requiring maintained supply chain stability and regulatory alignment, use of these active status substitutes is justified within the constraints of the provided parameters.

Frequently Asked Questions (FAQ)

Q: What determines if DMP3028LSD-13 or FDS6975 can substitute SP8J5FRATB?
A: The substitutes are chosen based on matching configuration (dual P-Channel), package (8-SOIC), current handling, Rds(on), gate threshold voltage, and compliance status.

Q: Are there differences in package or mounting type between these MOSFET substitutes?
A: All listed devices use the 8-SOIC or equivalent 8-SOP package and are designed for surface mount applications.

Q: Is automotive qualification (AEC-Q101) matched in the substitute parts?
A: Only information explicitly stated for this parameter is considered. No AEC-Q101 status is specified for the substitute parts in the provided data.

Q: Are the substitutes RoHS and REACH compliant?
A: All substitutes are listed as ROHS3 compliant and REACH unaffected.

Q: Is gate threshold voltage closely aligned between parts?
A: The main and substitute parts list a Vgs(th) in the 2.5V–3V range at similar test currents.

Q: Do substitutes maintain the same operating temperature range?
A: Operating temperature is listed as 150°C for the main part and -55°C ~ 150°C for the substitutes, meeting or exceeding the original part's range.

Q: What if the original part is no longer in stock?
A: For ongoing designs, use DMP3028LSD-13 or FDS6975 as alternatives that align in all strictly provided technical and compliance parameters.
