Parameter Comparison

Engineering Selection Recommendations

The ACGRC505-HF is the manufacturer-recommended substitute for the ACGRC505-G. Both parts are manufactured by Comchip Technology and maintain identical electrical and mechanical specifications across all critical parameters: 600V reverse voltage rating, 5A average rectified current, 1.15V forward voltage drop at 5A, standard recovery speed characteristics, and equivalent leakage current performance.

The primary distinction between these parts is product status: ACGRC505-G is designated Last Time Buy with 881 units in stock, while ACGRC505-HF maintains Active status with 790 units available. Both parts carry automotive-grade qualification (AEC-Q101), ROHS3 compliance, and MSL Level 1 moisture sensitivity rating, confirming suitability for automotive and industrial applications requiring equivalent reliability and environmental performance.

Selection between these parts should be based on inventory availability and supply chain continuity requirements. The ACGRC505-HF is recommended for new designs and long-term production planning due to its Active product status.

Frequently Asked Questions (FAQ)

Q: Can ACGRC505-HF directly replace ACGRC505-G in existing designs?
