CD214L-T7.5CALF Equivalent & Substitute Parts

Part Overview

The CD214L-T7.5CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This part operates with a 7.5V reverse standoff voltage and 12.9V maximum clamping voltage, capable of handling 232.6A peak pulse current at 3000W peak pulse power. The CD214L-T7.5CALF is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Direct functional equivalents are available from multiple manufacturers with identical or comparable electrical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CD214L-T7.5CALF is determined by strict equivalence across the following critical parameters:

Voltage - Reverse Standoff: 7.5V (exact match required)
Voltage - Clamping (Max) @ Ipp: 12.9V (exact match required)
Package / Case: DO-214AB, SMC (exact match required)
Mounting Type: Surface Mount (exact match required)
Bidirectional Channels: 1 (exact match required)
Type: Zener (exact match required)

Substitute parts are grouped into two categories based on peak pulse current and power handling capacity:

Category A - Full Electrical Equivalents (232.6A / 3000W): Parts with identical peak pulse current and power ratings to the original CD214L-T7.5CALF.

Category B - Reduced Current Equivalents (116.3A–122A / 1500W): Parts with lower peak pulse current and power ratings but identical voltage specifications and package configuration.

Engineering Selection Recommendations

Primary Substitutes (Full Electrical Equivalents):

SMLJ7.5CA (Bourns Inc., Active) and SMDJ7.5CA (Alpha & Omega Semiconductor Inc., Active) are direct functional replacements for the obsolete CD214L-T7.5CALF. Both parts maintain identical voltage specifications, peak pulse current (232.6A), and power handling (3000W). SMLJ7.5CA is available in Tape & Reel packaging with 3550 units in stock. SMDJ7.5CA is available with 22800 units in stock. Both are RoHS3 compliant and suitable for applications requiring the full 3000W power dissipation capability.

Secondary Substitutes (Reduced Current Equivalents):

SMCJ7.5CA (Taiwan Semiconductor Corporation, Active), SMCJ7.5CA-TP (Micro Commercial Co, Active), and SMCJ7V5CA (Fairchild Semiconductor, Active) provide voltage-equivalent substitution with reduced peak pulse current (116.3A–122A) and power handling (1500W). These parts are appropriate for applications where transient energy levels do not exceed 1500W. SMCJ7.5CA-TP offers extended operating temperature range (-55°C ~ 175°C) compared to the original specification. SMCJ7V5CA has the highest inventory availability (107400 units).

All substitute parts are RoHS3 compliant and classified as active products, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can SMCJ7.5CA be used as a direct replacement for CD214L-T7.5CALF?

A: SMCJ7.5CA is electrically compatible in terms of voltage specifications (7.5V standoff, 12.9V clamping) and package configuration (DO-214AB, SMC). However, it has reduced peak pulse current (122A vs. 232.6A) and power handling (1500W vs. 3000W). Use this substitute only if your application's transient energy requirements do not exceed 1500W.

Q: What is the difference between SMLJ7.5CA and SMDJ7.5CA?

A: Both SMLJ7.5CA and SMDJ7.5CA are full electrical equivalents with identical voltage and power specifications (232.6A, 3000W). The primary difference is manufacturer: SMLJ7.5CA is from Bourns Inc. and available in Tape & Reel packaging, while SMDJ7.5CA is from Alpha & Omega Semiconductor Inc. Both are active products suitable for direct substitution.

Q: Does packaging type affect electrical performance?

A: Packaging type (Tape & Reel vs. Bulk) does not affect electrical performance. It affects handling, storage, and assembly processes. SMLJ7.5CA is supplied in Tape & Reel format, while SMCJ7V5CA is supplied in Bulk. Select based on your production and inventory requirements.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts are RoHS3 compliant. The original CD214L-T7.5CALF is also RoHS3 compliant. Compliance status is consistent across all options.

Q: What is the operating temperature range for substitute parts?

A: Most substitute parts operate within -55°C ~ 150°C, matching the original CD214L-T7.5CALF specification. SMCJ7.5CA-TP extends this range to -55°C ~ 175°C. SMCJ7V5CA does not specify an operating temperature range in the provided data.

Q: Which substitute has the best inventory availability?

A: SMCJ7V5CA (Fairchild Semiconductor) has the highest inventory with 107400 units in stock. SMCJ7.5CA (Taiwan Semiconductor Corporation) has 15100 units. SMDJ7.5CA has 22800 units. SMLJ7.5CA has 3550 units.
