CPDER12V-HF Equivalent & Substitute Parts

Part Overview

The CPDER12V-HF is a Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This component features a 12V reverse standoff voltage with a 25V maximum clamping voltage and 1A peak pulse current rating in a compact 0503/SOD-723F surface mount package.

The CPDER12V-HF is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPDER12V-HF is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 12V
• Voltage - Breakdown (Min): 13V
• Voltage - Clamping (Max) @ Ipp: 25V
• Current - Peak Pulse (10/1000µs): 1A (8/20µs)
• Power - Peak Pulse: 25W
• Bidirectional Channels: 1
• Capacitance @ Frequency: 12pF @ 1MHz
• Package / Case: 0503 (1308 Metric)
• Supplier Device Package: 0503/SOD-723F
• Mounting Type: Surface Mount

The direct substitute CPDER12V matches all electrical and mechanical parameters of the CPDER12V-HF. The primary distinction is product status: CPDER12V is Active, whereas CPDER12V-HF is Obsolete. Both components are manufactured by Comchip Technology and share identical packaging, voltage ratings, current handling, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The CPDER12V is the direct equivalent substitute for the obsolete CPDER12V-HF. Both components are manufactured by Comchip Technology and maintain identical electrical specifications, mechanical dimensions, and compliance certifications.

Selection of CPDER12V over CPDER12V-HF is supported by:

• Active product status ensuring ongoing availability and manufacturing support
• ROHS3 compliance and REACH unaffected status matching the original component
• Unlimited moisture sensitivity level (MSL 1) suitable for standard storage and handling
• Tape & Reel packaging format supporting automated assembly processes

No electrical or mechanical redesign is required when substituting CPDER12V for CPDER12V-HF in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can CPDER12V be used as a direct replacement for CPDER12V-HF?

A: Yes. CPDER12V is a direct equivalent substitute. All electrical parameters, mechanical dimensions, and compliance certifications are identical. The primary difference is product status: CPDER12V is Active while CPDER12V-HF is Obsolete.

Q: Are there any differences in voltage ratings between CPDER12V and CPDER12V-HF?

A: No. Both components share identical voltage specifications: 12V reverse standoff voltage, 13V minimum breakdown voltage, and 25V maximum clamping voltage.

Q: What is the package compatibility between these parts?

A: Both CPDER12V and CPDER12V-HF use the 0503/SOD-723F surface mount package (0503 metric designation). They are mechanically and electrically interchangeable on PCBs designed for either component.

Q: Does the packaging format (Tape & Reel vs. other formats) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical and mechanical performance remains identical regardless of packaging format.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both CPDER12V and CPDER12V-HF are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these components?

A: Both components have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
