CD214C-T7.0CALF Equivalent & Substitute Parts

Part Overview

The CD214C-T7.0CALF is a 7V Zener transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface mount applications. This component features a 12V maximum clamping voltage, 125A peak pulse current capability, and 1500W peak pulse power rating in a DO-214AB (SMC) package. The part is currently classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the CD214C-T7.0CALF is determined by the following critical parameters:

Voltage - Reverse Standoff: 7V (exact match required)
Voltage - Clamping (Max) @ Ipp: 12V (exact match required)
Package / Case: DO-214AB, SMC (exact match required)
Mounting Type: Surface Mount (exact match required)
Current - Peak Pulse (10/1000µs): 125A minimum
Power - Peak Pulse: 1500W minimum
Operating Temperature Range: -55°C minimum to 150°C maximum
RoHS Compliance: ROHS3 Compliant

All substitute parts listed meet or exceed these parameters. Variations in peak pulse current and power ratings above the minimum threshold are acceptable for direct substitution, as they provide equivalent or enhanced protection capability.

Engineering Selection Recommendations

Primary Substitute: SMCJ7.0CA (Taiwan Semiconductor Corporation)

The SMCJ7.0CA is the preferred direct replacement for the CD214C-T7.0CALF. This part maintains identical voltage specifications (7V standoff, 12V clamping), equivalent current rating (131A vs. 125A), and matching power dissipation (1500W). The component is in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Inventory availability is substantial at 84,400 units.

Secondary Substitute: SMCJ7.0CA-TP (Micro Commercial Co)

The SMCJ7.0CA-TP offers an alternative with identical electrical parameters and extended operating temperature range (-55°C to 175°C). This part is supplied in Tape & Reel packaging, suitable for automated assembly processes. ROHS3 compliance is confirmed. Inventory is available at 3,858 units.

Alternative Substitute: SMCJ7V0CA (Fairchild Semiconductor)

The SMCJ7V0CA maintains all critical voltage and current specifications with matching 1500W power rating. This part is supplied in bulk packaging and is in active production. Operating temperature range is not specified in available documentation. Inventory availability is 18,400 units.

Enhanced Capability Substitute: SMDJ7.0CA (Alpha & Omega Semiconductor Inc.)

The SMDJ7.0CA provides superior performance characteristics with doubled peak pulse current (250A) and peak pulse power (3000W) while maintaining identical voltage specifications. This part is suitable for applications requiring enhanced transient protection margin. ROHS3 compliance is confirmed with active production status. Inventory is available at 12,400 units.

Frequently Asked Questions (FAQ)

Q: Can I use SMDJ7.0CA as a substitute for CD214C-T7.0CALF?

A: Yes. The SMDJ7.0CA meets all critical substitution parameters: 7V reverse standoff voltage, 12V clamping voltage, DO-214AB package, and surface mount configuration. The higher current rating (250A vs. 125A) and power dissipation (3000W vs. 1500W) provide enhanced protection capability without affecting circuit compatibility.

Q: What is the difference between SMCJ7.0CA and SMCJ7.0CA-TP?

A: Both parts have identical electrical specifications. The primary difference is packaging: SMCJ7.0CA is supplied in bulk, while SMCJ7.0CA-TP is supplied in Tape & Reel format. The SMCJ7.0CA-TP also specifies an extended operating temperature range to 175°C compared to 150°C for the standard version.

Q: Are all substitute parts RoHS compliant?

A: SMCJ7.0CA, SMCJ7.0CA-TP, and SMDJ7.0CA are confirmed ROHS3 compliant. SMCJ7V0CA RoHS status is not specified in available documentation and should be verified with the supplier before use in RoHS-restricted applications.

Q: Can I use these substitutes in high-temperature applications?

A: Most substitutes support the original -55°C to 150°C operating range. The SMCJ7.0CA-TP extends this to 175°C. SMCJ7V0CA operating temperature is not specified. Verify thermal requirements against your specific application before selection.

Q: What is the difference between the SMCJ and SMDJ series?

A: Both are 7V Zener TVS diodes in DO-214AB packages. The SMDJ7.0CA offers higher current and power ratings (250A, 3000W) compared to SMCJ variants (125-131A, 1500W). Selection depends on the transient energy levels in your circuit.
