Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for RB461F-TP are based strictly on identical or compatible electrical and mechanical parameters, specifically: Schottky technology, maximum DC reverse voltage (20 V), average rectified current (700 mA), maximum forward voltage (490 mV @ 700 mA), fast recovery speed, reverse leakage current (200 µA @ 20 V), surface mountability, and package compatibility (SC-70/SOT-323 or equivalent). Substitution is considered only where all parameters match as specified in the input.

Parameter Comparison

Engineering Selection Recommendations

RB461F-TP is not recommended for new designs due to its status as "Not For New Designs". Substitute selection should prioritize RB461FT106 by Rohm Semiconductor, which matches all critical operational parameters outlined above and maintains active product status. Both parts are REACH unaffected and classified as EAR99 for export compliance. The substitute part is RoHS3 compliant and has no stated moisture sensitivity limitations. Package and mounting type are compatible.

Frequently Asked Questions (FAQ)

Q: What parameters must be matched for direct substitution of RB461F-TP?
A: Substitution requires matching technology type (Schottky), DC reverse voltage (20 V), average rectified current (700 mA), forward voltage (490 mV @ 700 mA), switching speed, reverse leakage current, surface mount capability, package/case dimensions, and compliance status.

Q: Is package compatibility between RB461F-TP and RB461FT106 ensured?
A: Both devices are designed for surface mount applications in SC-70, SOT-323 compatible packages. Supplier device package names differ ("SOT-323" vs. "UMD3") but refer to the same mechanical outline in this context.

Q: Are there engineering concerns with the operating temperature range?
A: Both diodes are rated for elevated junction temperatures, RB461F-TP up to 150°C and RB461FT106 up to 125°C (Max), as provided. Selection should consider the application's maximum required junction temperature.

Q: Does compliance status affect substitution choice?
A: Both parts are REACH unaffected and classified under ECCN EAR99. RB461FT106 additionally specifies RoHS3 compliance and unlimited moisture sensitivity level (MSL 1), meeting standard semiconductor regulatory requirements.
