US6J2TR Equivalent & Substitute Parts Reference
Part Overview
The US6J2TR by Rohm Semiconductor is a dual P-channel MOSFET array rated at 20V, 1A, with a maximum power dissipation of 1W. It is designed for low-voltage, low-Rds(on), surface-mount applications in MOSFET, FETs, and transistor circuits. This part is "Not For New Designs," making it essential to identify equivalent or substitute models for ongoing or future electronic designs and production to fulfill availability and active production requirements.

Substitute Part Grouping Explanation
Substitute parts for the US6J2TR are determined strictly by matching critical allowed parameters relevant to the MOSFET category: configuration (2 P-Channel (Dual)), Vdss (20V), current rating (Id), Rds(on), logic level gate drive, power rating, mounting style (surface mount), and RoHS/REACH compliance. Substitute parts are grouped only if they strictly conform to these specification boundaries.
Key parameters for substitution:
- Configuration: 2 P-Channel (Dual)
- Drain to Source Voltage (Vdss): 20V
- Current - Continuous Drain (Id)
- Rds(on)
- Logic Level Gate
- Power Dissipation (W)
- Surface Mount Package
- RoHS and REACH compliance

Engineering Selection Recommendations
Both US6J2TR and IRF7104TRPBF have product status listed as "Not For New Designs" and are ROHS3 compliant with MSL 1 (Unlimited) and REACH Unaffected status. Selection among these parts must take into account their availability, compliance with RoHS and REACH, and their product status relative to required design lifecycles. Only listed and compliance-matching parts should be considered.
Frequently Asked Questions (FAQ)
Q: What are the critical parameters required to substitute US6J2TR?
A: Substitution requires equivalent configuration (2 P-Channel (Dual)), Vdss, current rating, Rds(on), logic gate compatibility, power rating, mounting type, package, and environmental compliance.
Q: Are differences in package size or type allowable according to the provided data?
A: Only surface-mount packages are considered within the substitution based on the input data. Review the provided package for footprint compatibility.
Q: Is RoHS/REACH compliance mandatory for substitutes?
A: Yes. Both main and substitute parts are listed as ROHS3 compliant and REACH Unaffected; these compliance conditions are mandatory.
Q: Can both the US6J2TR and IRF7104TRPBF be used in new designs?
A: Both parts are listed as Not For New Designs; this status should be adhered to in selection criteria.
Q: What package differences exist between the parts?
A: US6J2TR uses a 6-SMD, Flat Leads package (TUMT6), while IRF7104TRPBF is in an 8-SOIC package. Confirm compatibility with the target PCB layout before substitution.
