CPDER5V0H-HF Equivalent & Substitute Parts

Part Overview

The CPDER5V0H-HF is a Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This component features a 5V reverse standoff voltage with a 20V maximum clamping voltage and 7A peak pulse current capability in a compact 0503/SOD-723F surface mount package.

The CPDER5V0H-HF is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this TVS diode.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPDER5V0H-HF is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff: 5V nominal rating
• Voltage - Breakdown (Min): 5.5V or higher
• Bidirectional Channels: 1 channel configuration
• Type: Zener diode technology
• Applications: General Purpose overvoltage protection

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package Category: Compact form factor (0402/0503 metric range)
• Moisture Sensitivity Level: MSL 1 or equivalent

The substitute part D5V0L1B2LP-7B meets these criteria with a 5V reverse standoff voltage, 6V minimum breakdown voltage, and surface mount configuration. While the clamping voltage (14V) and peak pulse current (6A) differ from the original specification, these parameters remain within acceptable ranges for general-purpose TVS applications and do not preclude functional substitution in the intended application category.

Engineering Selection Recommendations

The D5V0L1B2LP-7B is the manufacturer-recommended substitute for the obsolete CPDER5V0H-HF. Selection of this substitute is supported by the following factors:

Product Status: The D5V0L1B2LP-7B maintains Active product status with confirmed inventory availability (125,100 pcs), ensuring long-term supply chain continuity compared to the obsolete CPDER5V0H-HF.

Compliance & Certifications: The D5V0L1B2LP-7B is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement. Both parts share identical MSL 1 (Unlimited) moisture sensitivity ratings.

Electrical Equivalence: Both parts operate at 5V reverse standoff voltage with single-channel bidirectional Zener diode configuration, maintaining functional compatibility for general-purpose overvoltage protection circuits.

Package Consideration: The D5V0L1B2LP-7B uses a smaller 0402 (1006 Metric) package compared to the original 0503 (1308 Metric) package. This reduction in physical footprint may require PCB layout verification to confirm fit within existing design constraints.

Frequently Asked Questions (FAQ)

Q: Can the D5V0L1B2LP-7B directly replace the CPDER5V0H-HF without circuit modifications?

A: The D5V0L1B2LP-7B is electrically compatible for general-purpose TVS applications due to matching 5V reverse standoff voltage and single-channel Zener configuration. However, the smaller package footprint (0402 vs. 0503) requires PCB layout verification. The lower clamping voltage (14V vs. 20V) and reduced peak pulse current (6A vs. 7A) must be evaluated against specific circuit protection requirements.

Q: What are the key differences in electrical performance between these parts?

A: The primary electrical differences are clamping voltage (D5V0L1B2LP-7B: 14V maximum vs. CPDER5V0H-HF: 20V maximum) and peak pulse current capability (D5V0L1B2LP-7B: 6A vs. CPDER5V0H-HF: 7A). Both parts maintain identical 5V reverse standoff voltage ratings and MSL 1 moisture sensitivity levels. The D5V0L1B2LP-7B exhibits lower capacitance (15pF vs. 20pF @ 1MHz).

Q: Is the package size change from 0503 to 0402 a concern?

A: The package reduction from 0503 (1308 Metric) to 0402 (1006 Metric) represents a smaller physical footprint. Existing PCB designs must be reviewed to confirm that the reduced component size accommodates current pad layouts and routing constraints. No electrical performance impact results from this package change.

Q: What compliance advantages does the D5V0L1B2LP-7B offer?

A: The D5V0L1B2LP-7B is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards. The CPDER5V0H-HF compliance status is not specified. Both parts carry identical EAR99 ECCN and 8541.10.0080 HTSUS classifications.

Q: How does the Active product status of D5V0L1B2LP-7B benefit procurement?

A: Active product status ensures ongoing manufacturing, documented supply chain availability (125,100 pcs in stock), and manufacturer support. The obsolete status of CPDER5V0H-HF creates supply risk and limits access to technical documentation or future inventory replenishment.
