Substitute Part Grouping Explanation
Substitution eligibility for the ACPDUC24V-HF is determined by strict equivalence across the following critical parameters:
Electrical Parameters (Must Match):
- Voltage - Reverse Standoff (Typ): 24V
- Voltage - Breakdown (Min): 25V
- Voltage - Clamping (Max) @ Ipp: 47V
- Current - Peak Pulse (10/1000µs): 1A (8/20µs)
- Power - Peak Pulse: 47W
- Capacitance @ Frequency: 10pF @ 1MHz
- Type: Zener
- Bidirectional Channels: 1
Mechanical Parameters (Must Match):
- Package / Case: 2-SMD, No Lead
- Mounting Type: Surface Mount
- Supplier Device Package: 0603C/SOD-523F or 0603/SOD-523F
Compliance Parameters (Must Match):

Engineering Selection Recommendations
All substitute parts are Active status components manufactured by Comchip Technology with ROHS3 compliance and AEC-Q101 automotive qualification. Selection among ACPDUC24V-HF, CPDU24V, CPDU24V-HF, CPDUR24V, and CPDUR24V-HF is based on inventory availability and package designation requirements.
The ACPDUC24V-HF specifies 0603C/SOD-523F packaging. The substitute parts CPDU24V, CPDU24V-HF, CPDUR24V, and CPDUR24V-HF specify 0603/SOD-523F packaging. Both package designations are mechanically and electrically compatible for surface mount assembly in 0603 form factor applications.
CPDU24V-HF offers the highest inventory availability (381,400 units) and is suitable for high-volume production requirements. CPDUR24V provides substantial inventory (129,106 units) for standard production volumes. CPDUR24V-HF (8,469 units) and CPDU24V (1,687 units) support lower-volume applications. All parts maintain identical electrical performance and compliance certifications.
Frequently Asked Questions (FAQ)
Q: Can CPDU24V-HF be used as a direct replacement for ACPDUC24V-HF?
A: Yes. Both parts are electrically and mechanically equivalent 24V TVS diodes with identical voltage ratings (24V reverse standoff, 47V clamping), current handling (1A peak pulse), and power dissipation (47W). Both are ROHS3 compliant, MSL 1, and Active status. The package designation difference (0603C/SOD-523F versus 0603/SOD-523F) does not affect compatibility in 0603 surface mount applications.
Q: What is the difference between the CPDU and CPDUR part number series?
A: Both series are manufactured by Comchip Technology and share identical electrical specifications for the 24V rating. The part number designation reflects internal product line organization but does not indicate functional or performance differences. All parts in both series are direct substitutes.
Q: Are the -HF suffix variants different from non-HF variants?
A: The -HF designation appears in the part number but does not indicate a functional difference in the provided electrical or mechanical parameters. All variants (with and without -HF) maintain identical voltage ratings, current handling, power dissipation, and package specifications.
Q: Can these parts be used in automotive applications?
A: Yes. All parts carry AEC-Q101 automotive qualification and Automotive grade designation, confirming suitability for automotive transient voltage suppression applications.
Q: What is the moisture sensitivity level for these parts?
A: All parts are MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
