CPDU12V-HF Equivalent & Substitute Parts

Part Overview

The CPDU12V-HF 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 operates at 12V reverse standoff with a 25V maximum clamping voltage and 1A peak pulse current rating. The component is actively produced and ROHS3 compliant, making it suitable for modern electronic designs requiring transient voltage suppression in compact form factors.

Substitute parts are identified when electrical characteristics, mechanical packaging, and compliance certifications remain identical across different part number variants or packaging configurations, enabling design flexibility and supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for CPDU12V-HF is determined by strict equivalence across the following criteria:

Electrical Parameters (Must Match Exactly):

• Voltage - Reverse Standoff: 12V
• Voltage - Breakdown (Min): 13V
• Voltage - Clamping (Max) @ Ipp: 25V
• Current - Peak Pulse: 1A (8/20µs)
• Power - Peak Pulse: 25W
• Capacitance @ 1MHz: 12pF

Mechanical Parameters (Must Match Exactly):

• Package / Case: 2-SMD, No Lead
• Supplier Device Package: 0603/SOD-523F
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

Compliance & Status (Must Match Exactly):

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts meet these criteria. Packaging configuration (Tape & Reel vs. Cut Tape) does not affect electrical or mechanical compatibility and represents a supply chain variant only.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts—CPDU12V, CPDUR12V, and CPDUR12V-HF—are electrically and mechanically equivalent to CPDU12V-HF and are suitable for direct substitution in circuit designs. Selection among these equivalents should be based on:

Packaging Configuration: CPDU12V and CPDUR12V-HF are supplied in Tape & Reel (TR) format, while CPDUR12V is supplied in Cut Tape (CT) & Digi-Reel® format. Choose based on assembly equipment compatibility and procurement workflow.

Product Status & Compliance: All parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance for modern applications.

Supply Chain Availability: Inventory levels vary across part numbers. CPDUR12V-HF offers the highest stock availability (127,745 Pcs), followed by CPDUR12V (57,215 Pcs), CPDU12V (18,710 Pcs), and CPDU12V-HF (4,300 Pcs). Selection may be influenced by lead time requirements and procurement strategy.

Frequently Asked Questions (FAQ)

Q: Can CPDU12V be used as a direct replacement for CPDU12V-HF?

A: Yes. CPDU12V is electrically and mechanically identical to CPDU12V-HF. Both are 12V Zener TVS diodes in 0603/SOD-523F surface-mount packages with identical voltage ratings, current handling, and compliance certifications. The difference is packaging configuration (both Tape & Reel) and inventory availability.

Q: What is the difference between CPDUR12V and CPDU12V?

A: The electrical and mechanical specifications are identical. The primary difference is packaging configuration: CPDUR12V is supplied in Cut Tape (CT) & Digi-Reel® format, while CPDU12V is supplied in Tape & Reel (TR) format. Selection depends on assembly line equipment and procurement requirements.

Q: Is CPDUR12V-HF compatible with designs specified for CPDU12V-HF?

A: Yes. CPDUR12V-HF is fully compatible. All electrical parameters, mechanical dimensions, package type (0603/SOD-523F), and compliance certifications are identical. The "-HF" designation and packaging configuration do not affect circuit performance or pin compatibility.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts—CPDU12V-HF, CPDU12V, CPDUR12V, and CPDUR12V-HF—have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any differences in RoHS or REACH compliance between these parts?

A: No. All substitute parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for use in regulated markets and applications.

Q: Which part should be selected for highest availability?

A: CPDUR12V-HF offers the highest inventory level at 127,745 Pcs. If supply chain continuity is a priority, this part number is recommended. All parts are electrically and mechanically interchangeable.
