ACPDQC5V0-HF Equivalent & Substitute Parts
Part Overview
The ACPDQC5V0-HF is a 5V Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for surface mount applications in the SOD-923 package. This bidirectional Zener diode provides transient voltage protection with a 15V maximum clamping voltage and 5A peak pulse current rating (8/20µs). The device is AEC-Q101 qualified for automotive applications and carries Active product status with ROHS3 compliance.
Equivalent and substitute parts are identified based on matching electrical performance parameters: reverse standoff voltage, clamping voltage, peak pulse current, and compatible surface mount packaging. Substitutes may vary in specific package dimensions, capacitance characteristics, and temperature operating ranges while maintaining functional equivalence for transient suppression applications.

Substitute Part Grouping Explanation
Substitution eligibility is determined by the following critical electrical parameters:
- Voltage - Reverse Standoff: 5V nominal (acceptable range 5V to 5.5V maximum)
- Voltage - Clamping (Max) @ Ipp: 14V to 15V range
- Current - Peak Pulse (8/20µs): minimum 5A
- Package / Case: Surface mount 0402 metric equivalent or smaller footprint
- Type: Zener diode, bidirectional, single channel
- Compliance: ROHS3 compliant, MSL 1
Substitute parts are grouped into two categories:
Direct Manufacturer Equivalents (Comchip Technology): Parts with identical electrical specifications and packaging from the same manufacturer, differing only in inventory or minor packaging variants.
Cross-Manufacturer Substitutes: Parts from alternative manufacturers (Diodes Incorporated, Nexperia USA Inc., Alpha & Omega Semiconductor Inc., Bourns Inc.) that meet the core electrical parameters within acceptable tolerances. These substitutes maintain functional equivalence while offering different package options, temperature ratings, or capacitance characteristics.

Engineering Selection Recommendations
Primary Substitutes (Highest Compatibility):
CPDQC5V0-HF (Comchip Technology) is the direct equivalent with identical electrical specifications and packaging. This part maintains full functional parity with the ACPDQC5V0-HF and is recommended as the first choice for direct replacement.
DESD5V0S1BL-7B and DESD5V0S1BLD-7B (Diodes Incorporated) provide enhanced peak pulse current capability (12A versus 5A) while maintaining the 5V reverse standoff and 14V clamping voltage. These parts are suitable for applications requiring higher transient current handling. Both parts carry ROHS3 compliance and MSL 1 rating.
PESD5V0S1BL,315 (Nexperia USA Inc.) matches the electrical performance envelope with 5V reverse standoff, 14V clamping, and 12A peak pulse current. This part is ROHS3 compliant with extended temperature range (-65°C to 150°C) and is suitable for automotive and industrial applications.
Secondary Substitutes (Parameter Variations):
PESD5V0F1BL,315 (Nexperia USA Inc.) provides 5.5V reverse standoff with 15V clamping voltage, matching the original clamping specification. However, peak pulse current is limited to 2.5A, making this suitable only for lower-current transient suppression applications. AEC-Q101 qualification is provided.
AOZ8131DI-05L (Alpha & Omega Semiconductor Inc.) offers 5V reverse standoff but with elevated 22V clamping voltage and reduced 4A peak pulse current. This part is suitable for applications where higher clamping voltage is acceptable and current requirements are lower.
Not Recommended for Direct Substitution:
CDDFN2-T3.3B (Bourns Inc.) has 3.3V reverse standoff, which deviates from the 5V specification and is not suitable for 5V protection circuits.
DESDALC5LP-7B (Diodes Incorporated) has 3V reverse standoff, outside the acceptable range for 5V applications.
PESD12VV1BL,315 and PESD18VF1BLYL (Nexperia USA Inc.) have reverse standoff voltages of 12V and 18V respectively, designed for higher voltage protection circuits and are not compatible with 5V applications.
All recommended substitutes maintain ROHS3 compliance and MSL 1 moisture sensitivity rating. Product status is Active for all listed parts.
Frequently Asked Questions (FAQ)
Q: Can DESD5V0S1BL-7B replace ACPDQC5V0-HF in my circuit?
A: Yes. DESD5V0S1BL-7B maintains the critical 5V reverse standoff voltage and 14V clamping voltage specifications. The higher peak pulse current (12A versus 5A) provides additional margin for transient suppression. Package differences (0402 metric versus SOD-923) require PCB layout verification for footprint compatibility.
Q: What is the difference between PESD5V0S1BL,315 and PESD5V0F1BL,315?
A: Both parts have 5V reverse standoff voltage. PESD5V0S1BL,315 provides 14V clamping with 12A peak pulse current, matching the original specification. PESD5V0F1BL,315 provides 15V clamping but with only 2.5A peak pulse current. Selection depends on whether peak current capacity or exact clamping voltage is the priority for your application.
Q: Are all substitute parts automotive qualified?
A: ACPDQC5V0-HF, PESD5V0F1BL,315, and PESD12VV1BL,315 carry AEC-Q101 automotive qualification. DESD5V0S1BL-7B, DESD5V0S1BLD-7B, PESD5V0S1BL,315, and others are ROHS3 compliant but do not list AEC-Q101 qualification. Verify automotive qualification requirements for your specific application.
Q: What does reverse standoff voltage mean?
A: Reverse standoff voltage is the maximum voltage the TVS diode can withstand in its normal operating state without conducting. For the ACPDQC5V0-HF, this is 5V. Substitute parts must maintain this specification to protect 5V circuits correctly.
Q: Can I use CDDFN2-T3.3B as a substitute?
A: No. CDDFN2-T3.3B has a 3.3V reverse standoff voltage, which is below the 5V requirement. Using this part in a 5V circuit would result in premature conduction and inadequate protection.
Q: What is the significance of capacitance at 1MHz?
A: Capacitance affects high-frequency circuit behavior. The original ACPDQC5V0-HF has 15pF capacitance. Substitutes with significantly different capacitance (such as PESD5V0F1BL,315 at 0.4pF) may alter circuit impedance and signal integrity in RF or high-speed applications. Verify capacitance compatibility for frequency-sensitive circuits.
Q: Are there inventory considerations for substitution?
A: Yes. DESD5V0S1BL-7B has 611,300 units in stock, PESD5V0F1BL,315 has 251,649 units, and PESD5V0S1BL,315 has 27,119 units. The original ACPDQC5V0-HF has 1,498 units available. Higher inventory parts may offer better lead time and cost advantages.
Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?
A: Tape & Reel (TR) packaging is suitable for automated assembly processes and high-volume production. Cut Tape (CT) is used for lower-volume or manual assembly. Both formats contain the same component; packaging choice depends on manufacturing process requirements.
