Substitute Part Grouping Explanation

Substitution eligibility for the ACGRC502-G is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 5 A
• Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 5 A
• Current - Reverse Leakage @ Vr: 5 µA @ 100 V
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Capacitance @ Vr, F: 25 pF @ 4V, 1MHz

Mechanical & Package Parameters (Must Match):

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount

Compliance & Grade Parameters (Must Match):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Operating Conditions (Must Match):

Substitute parts must satisfy all parameters listed above without deviation. Product status and inventory availability are secondary considerations and do not affect substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The ACGRC502-HF is a direct electrical and mechanical equivalent to the ACGRC502-G. Both parts are manufactured by Comchip Technology and satisfy identical electrical specifications, package requirements, and automotive-grade compliance standards including AEC-Q101 qualification.

The primary distinction between these parts is product status: ACGRC502-G is designated Last Time Buy, while ACGRC502-HF maintains Active status with higher inventory availability (1053 units versus 746 units). For new designs or production continuity, ACGRC502-HF is the appropriate selection. For existing designs currently specified with ACGRC502-G, substitution with ACGRC502-HF requires no circuit modifications or re-qualification, as all electrical and mechanical parameters are identical.

Both parts comply with ROHS3 requirements and carry MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special storage or handling requirements beyond standard component practices.

Frequently Asked Questions (FAQ)

Q: Can ACGRC502-HF be used as a direct replacement for ACGRC502-G in existing designs?

A: Yes. ACGRC502-HF is electrically and mechanically equivalent to ACGRC502-G. All critical parameters including reverse voltage rating (100V), average rectified current (5A), forward voltage drop (1.15V @ 5A), package type (DO-214AB/SMC), and automotive qualification (AEC-Q101) are identical. No circuit modifications are required.

Q: What is the difference between ACGRC502-G and ACGRC502-HF?

A: The parts are functionally identical. The primary difference is product lifecycle status: ACGRC502-G is Last Time Buy (discontinued), while ACGRC502-HF is Active production. The suffix designation (-G versus -HF) indicates different manufacturing or packaging variants from Comchip Technology, but electrical performance and package specifications remain unchanged.

Q: Are both parts suitable for automotive applications?

A: Yes. Both ACGRC502-G and ACGRC502-HF carry Automotive grade classification and AEC-Q101 qualification, confirming suitability for automotive circuit applications within the specified operating temperature range (-55°C to 150°C junction temperature).

Q: What is the DO-214AB package, and is it the same as SMC?

A: DO-214AB and SMC (Surface Mount Case) refer to the same surface mount diode package. This is a standard industry designation for small surface mount rectifier diodes with two leads. Both parts use this identical package, ensuring PCB footprint and reflow soldering compatibility.

Q: Are there any moisture sensitivity or storage concerns with these diodes?

A: No. Both parts carry MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special moisture control or baking requirements. Standard component storage practices are sufficient.

Q: What is the recovery speed specification, and why does it matter?

A: Both parts specify Standard Recovery with >500ns recovery time at >200mA forward current. This parameter defines the diode's switching speed and is critical for applications involving AC rectification or high-frequency switching. Identical specifications ensure equivalent performance in these applications.

Q: Can these diodes be used in parallel for higher current applications?

A: Current sharing in parallel diode configurations depends on forward voltage matching and thermal management. The identical Vf specifications (1.15V @ 5A) between ACGRC502-G and ACGRC502-HF support equivalent parallel operation characteristics, but parallel configuration design requires additional thermal and current distribution analysis beyond the scope of this substitution reference.
