Substitute Part Grouping Explanation

Substitution of the ACGRBT301-HF is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 3 A
Voltage - Forward (Vf) (Max) @ If: 1 V @ 3 A
Current - Reverse Leakage @ Vr: 5 µA @ 200 V
Operating Temperature - Junction: -65°C to 175°C
Package / Case: 2-SMD, No Lead (Surface Mount)
RoHS Status: ROHS3 Compliant

The substitute part CD214C-S3D manufactured by Bourns Inc. meets all critical electrical parameters and mechanical packaging requirements. Differences in recovery speed classification and capacitance specification do not affect substitution validity within the allowed parameter set for this product category.

Engineering Selection Recommendations

ACGRBT301-HF (Primary Part - Last Time Buy Status): This part is designated Last Time Buy, indicating end-of-life status. Existing inventory of 1,095 pieces is available. Selection of this part is appropriate only for immediate requirements or existing stock management. The part carries AEC-Q101 automotive qualification and ROHS3 compliance.

CD214C-S3D (Substitute Part - Active Status): This part is in Active product status with 716 pieces in current inventory. CD214C-S3D is manufactured by Bourns Inc. and meets all critical electrical and mechanical parameters specified for the ACGRBT301-HF. The substitute part maintains ROHS3 compliance and identical thermal operating range. Selection of CD214C-S3D is appropriate for new designs and long-term procurement requirements due to active manufacturing status.

Both parts are classified under ECCN EAR99 and HTSUS 8541.10.0080, with identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can CD214C-S3D directly replace ACGRBT301-HF in existing designs?

A: Yes. CD214C-S3D meets all critical electrical parameters: 200 V reverse voltage, 3 A average rectified current, 1 V forward voltage at 3 A, and 5 µA reverse leakage current. Both parts operate across -65°C to 175°C and use identical 2-SMD, No Lead surface mount packaging. Footprint and pinout compatibility are maintained.

Q: What is the difference in recovery speed between these parts?

A: ACGRBT301-HF is classified as Fast Recovery (≤ 500ns at > 200mA), while CD214C-S3D is classified as Standard Recovery (> 500ns at > 200mA). This difference does not affect substitution validity within the allowed parameter set for general-purpose rectifier applications at the specified current and voltage ratings.

Q: Are there compliance or certification differences?

A: ACGRBT301-HF carries AEC-Q101 automotive qualification. CD214C-S3D does not list this qualification in the provided parameters. Both parts are ROHS3 compliant. Applications requiring AEC-Q101 certification must verify CD214C-S3D qualification status through the manufacturer.

Q: Why is ACGRBT301-HF designated Last Time Buy?

A: Last Time Buy status indicates Comchip Technology has discontinued production of this part. Existing inventory is limited to 1,095 pieces. For applications requiring long-term component availability, CD214C-S3D is recommended due to its Active product status.

Q: Are the packages physically identical?

A: Both parts use 2-SMD, No Lead surface mount packaging with identical mechanical specifications. No PCB layout modifications are required for substitution.
