CPDER5V0 Equivalent & Substitute Parts Reference

Part Overview

The CPDER5V0 is a transient voltage suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional Zener diode features a 5V reverse standoff voltage with 15V maximum clamping voltage and 5A peak pulse current capability in the 0503/SOD-723F package. The part is active in production status and ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified to provide design flexibility when the original CPDER5V0 is unavailable or when alternative packaging formats are required for manufacturing optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CPDER5V0 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff: 5V nominal
• Bidirectional Channels: 1
• Type: Zener
• Category: Transient Voltage Suppressors (TVS)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Voltage - Clamping (Max) @ Ipp: 14V to 15V range
• Current - Peak Pulse (8/20µs): 5A to 6A range
• Power - Peak Pulse: 75W to 84W range
• Voltage - Breakdown (Min): 5.1V to 6V range
• Package / Case: 0402 (1006 Metric) or 0503 (1308 Metric)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®

The substitute parts D5V0L1B2LP-7B and D5V0L1B2LP4-7B, both manufactured by Diodes Incorporated, meet these criteria with equivalent electrical performance and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts D5V0L1B2LP-7B and D5V0L1B2LP4-7B are qualified alternatives to the CPDER5V0 based on electrical parameter compatibility and regulatory compliance. All three parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring equivalent environmental and handling requirements.

The primary distinction between the two Diodes Incorporated substitutes is packaging format: D5V0L1B2LP-7B is supplied in Cut Tape (CT) & Digi-Reel® format, while D5V0L1B2LP4-7B is supplied in Tape & Reel (TR) format. Selection between these options depends on manufacturing process requirements and inventory management practices.

The substitute parts feature slightly enhanced electrical performance with 6A peak pulse current and 84W peak pulse power compared to the CPDER5V0 specifications, providing additional margin in transient protection applications. The 14V maximum clamping voltage of the substitutes is within acceptable tolerance relative to the 15V specification of the main part.

Frequently Asked Questions (FAQ)

Q: Can D5V0L1B2LP-7B and D5V0L1B2LP4-7B be used interchangeably with CPDER5V0?

A: Yes, both Diodes Incorporated parts are electrically equivalent substitutes. The primary difference is packaging format: D5V0L1B2LP-7B uses Cut Tape & Digi-Reel® while D5V0L1B2LP4-7B uses Tape & Reel. Both meet the same electrical specifications and compliance requirements.

Q: What is the difference between the two substitute parts?

A: D5V0L1B2LP-7B and D5V0L1B2LP4-7B are identical in electrical performance and package type (0402/1006 Metric). The distinction is packaging format: one is supplied on cut tape with Digi-Reel®, the other on standard tape and reel. Selection depends on your assembly equipment and supply chain requirements.

Q: Are there package size differences between the main part and substitutes?

A: Yes. The CPDER5V0 uses the 0503 (1308 Metric) package, while both substitute parts use the 0402 (1006 Metric) package. The 0402 package is smaller and may require PCB layout adjustment. Verify footprint compatibility before design implementation.

Q: Do the substitute parts have the same voltage ratings?

A: The reverse standoff voltage is equivalent at 5V. The substitute parts have a minimum breakdown voltage of 6V compared to 5.1V for the CPDER5V0, and a maximum clamping voltage of 14V compared to 15V. These variations remain within acceptable tolerance for general-purpose TVS applications.

Q: Are all three parts RoHS compliant?

A: Yes. CPDER5V0, D5V0L1B2LP-7B, and D5V0L1B2LP4-7B are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, ensuring equivalent environmental and handling requirements.
