Engineering Selection Recommendations

RSFGLHRTG (Primary Reference) The RSFGLHRTG is the recommended selection for new designs. This part maintains Active product status and carries automotive-grade AEC-Q101 qualification. All electrical and mechanical parameters are identical to substitute options.

RSFGL (Parametric Equivalent) The RSFGL is a parametric equivalent with identical electrical specifications and mechanical compatibility. However, this part carries Not For New Designs product status. Selection of RSFGL is appropriate only for legacy system maintenance, repair, or applications where design freeze conditions apply. The part is supplied in Tape & Reel (TR) packaging format.

RSFGL RVG (Parametric Equivalent) The RSFGL RVG is a parametric equivalent with identical electrical specifications and mechanical compatibility. This part maintains Active product status and is suitable for new designs. The part is supplied in Cut Tape (CT) packaging format, which may be appropriate for lower-volume applications or manual assembly processes.

All three parts comply with ROHS3, REACH Unaffected, and automotive-grade requirements. Selection between RSFGLHRTG and RSFGL RVG for new designs depends on packaging format requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can RSFGL be used as a direct replacement for RSFGLHRTG?

A: RSFGL is electrically and mechanically equivalent to RSFGLHRTG. However, RSFGL carries Not For New Designs product status. Direct substitution is permissible for existing applications, repair, or legacy system support. For new designs, RSFGLHRTG or RSFGL RVG are the appropriate selections.

Q: What is the difference between RSFGLHRTG and RSFGL RVG?

A: RSFGLHRTG and RSFGL RVG are electrically and mechanically identical. The primary difference is packaging format: RSFGLHRTG uses standard packaging, while RSFGL RVG is supplied in Cut Tape (CT) format. Both parts maintain Active product status and are suitable for new designs.

Q: Are all substitute parts automotive-grade qualified?

A: All three parts (RSFGLHRTG, RSFGL, and RSFGL RVG) meet automotive-grade specifications and carry AEC-Q101 qualification. All parts comply with ROHS3 and REACH Unaffected requirements.

Q: Does packaging format affect electrical performance?

A: Packaging format (Tape & Reel, Cut Tape, or standard) does not affect electrical performance or mechanical compatibility. Format selection is determined by assembly process requirements and supply chain logistics.

Q: What is the reverse recovery time specification?

A: All substitute parts have a reverse recovery time (trr) of 150 ns, classifying them as fast recovery diodes with switching capability suitable for high-frequency rectification applications.

Q: Can these parts be used in automotive applications?
