CPDERT5V0 Equivalent & Substitute Parts

Part Overview

The CPDERT5V0 is a transient voltage suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This part operates with a 5V reverse standoff voltage and provides 15V maximum clamping voltage at peak pulse current. The CPDERT5V0 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPDERT5V0 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff: 5V nominal
• Voltage - Breakdown (Min): 5.1V or higher
• Voltage - Clamping (Max) @ Ipp: 15V or lower
• Current - Peak Pulse (8/20µs): 5A or higher
• Power - Peak Pulse: 75W or higher
• Bidirectional Channels: 1
• Capacitance @ 1MHz: 15pF nominal

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: 0503 (1308 Metric) or equivalent footprint
• Supplier Device Package: 0503/SOD-723F or compatible

Substitute Parts Identified:

1. Comchip Technology Direct Equivalents (CPDER5V0, CPDER5V0-HF): Identical electrical specifications and 0503/SOD-723F packaging. Both are active products with ROHS3 compliance.

2. Diodes Incorporated Cross-Substitutes (D5V0L1B2LP-7B, D5V0L1B2LP4-7B): Meet electrical requirements with enhanced specifications (6A peak pulse current, 84W power dissipation, 14V clamping voltage). Package footprint differs (0402/1006 Metric vs. 0503/1308 Metric), requiring PCB layout evaluation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No PCB Modification Required):

CPDER5V0 and CPDER5V0-HF are the primary substitutes for CPDERT5V0. Both parts maintain identical electrical specifications and 0503/SOD-723F packaging, ensuring direct footprint compatibility. Both are active products with ROHS3 compliance and unlimited moisture sensitivity rating. CPDER5V0 is available in Tape & Reel packaging with 652 pieces in stock, while CPDER5V0-HF is also available in Tape & Reel with 767 pieces in stock.

For Enhanced Performance (PCB Layout Evaluation Required):

D5V0L1B2LP-7B and D5V0L1B2LP4-7B, manufactured by Diodes Incorporated, provide superior electrical performance with 6A peak pulse current and 84W power dissipation compared to the 5A and 75W specifications of CPDERT5V0. These parts feature lower clamping voltage (14V vs. 15V) and specified operating temperature range (-65°C ~ 150°C). However, the package footprint differs (0402/1006 Metric vs. 0503/1308 Metric), requiring PCB layout modification. D5V0L1B2LP-7B is available in Cut Tape & Digi-Reel with 125,100 pieces in stock. D5V0L1B2LP4-7B is available in Tape & Reel with 73,686 pieces in stock.

All substitute parts carry ROHS3 compliance and REACH Unaffected status, matching the regulatory requirements of the original part.

Frequently Asked Questions (FAQ)

Q: Can CPDER5V0 be used as a direct replacement for CPDERT5V0?

A: Yes. CPDER5V0 is a direct substitute with identical electrical specifications (5V reverse standoff, 5.1V breakdown minimum, 15V clamping maximum, 5A peak pulse current, 75W power dissipation) and matching 0503/SOD-723F packaging. No PCB modifications are required.

Q: What is the difference between CPDER5V0 and CPDER5V0-HF?

A: Both parts are electrically identical with the same specifications and 0503/SOD-723F packaging. The "-HF" designation indicates a variant, but electrical and mechanical parameters remain equivalent for substitution purposes.

Q: Can Diodes Incorporated D5V0L1B2LP-7B or D5V0L1B2LP4-7B replace CPDERT5V0?

A: These parts meet the electrical requirements with enhanced specifications (6A peak pulse current vs. 5A, 84W power dissipation vs. 75W, 14V clamping vs. 15V). However, the package footprint differs (0402/1006 Metric vs. 0503/1308 Metric), requiring PCB layout evaluation and potential redesign.

Q: What are the key electrical parameters that determine substitution compatibility?

A: The critical parameters are reverse standoff voltage (5V), breakdown voltage minimum (5.1V or higher), clamping voltage maximum (15V or lower), peak pulse current (5A or higher), and power dissipation (75W or higher). All substitute parts meet or exceed these specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. CPDER5V0, CPDER5V0-HF, D5V0L1B2LP-7B, and D5V0L1B2LP4-7B are all ROHS3 compliant with REACH Unaffected status.

Q: What is the difference between D5V0L1B2LP-7B and D5V0L1B2LP4-7B?

A: Both parts are electrically identical with the same specifications and X2-DFN1006-2 packaging. The primary difference is packaging format: D5V0L1B2LP-7B is supplied in Cut Tape & Digi-Reel, while D5V0L1B2LP4-7B is supplied in Tape & Reel.

Q: Does package size affect circuit performance?

A: Package size does not affect electrical performance. However, the 0402 (1006 Metric) footprint of Diodes Incorporated parts is smaller than the 0503 (1308 Metric) footprint of Comchip parts, requiring PCB layout modification if switching between these packages.
