CD214L-T60ALF Equivalent & Substitute Parts

Part Overview

The CD214L-T60ALF is a 60V unidirectional transient voltage suppressor (TVS) diode manufactured by Bourns Inc. in the DO-214AB (SMC) surface mount package. This component is designed for general-purpose transient voltage protection with a peak pulse power rating of 3000W and peak pulse current of 31A. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production requirements.

Substitute Part Grouping Explanation

Substitution for the CD214L-T60ALF is determined by the following critical parameters:

Voltage - Reverse Standoff: 60V (exact match required)
Voltage - Clamping (Max) @ Ipp: 96.8V (exact match required)
Package / Case: DO-214AB, SMC (exact match required)
Unidirectional Channels: 1 (exact match required)
Type: Zener (exact match required)

Substitute parts are grouped into two categories:

Direct Equivalent (Identical Electrical Performance): Parts with matching voltage ratings, clamping voltage, peak pulse current of 31A, and 3000W power dissipation. These provide pin-for-pin and functional equivalence.

Similar Substitute (Compatible Electrical Performance): Parts with matching voltage ratings and clamping voltage but differing peak pulse current and power dissipation ratings. These are suitable when the application can tolerate higher current handling or power ratings.

Engineering Selection Recommendations

Primary Recommendation: SMLJ60A (Bourns Inc.) is the direct equivalent replacement. It maintains identical electrical specifications (60V standoff, 96.8V clamping, 31A peak pulse, 3000W power) and is manufactured by the original supplier. Active product status ensures long-term availability and supply chain stability.

Secondary Recommendation: SMDJ60A (Alpha & Omega Semiconductor Inc.) provides identical electrical performance with matching voltage ratings, peak pulse current, and power dissipation. Active status and ROHS3 compliance support modern design requirements.

Higher Power Alternative: 5.0SMDJ60A and 5.0SMDJ60A-T7 offer enhanced current handling (51.7A) and power dissipation (5000W) while maintaining the same voltage protection characteristics. These are suitable for applications requiring additional transient energy absorption margin. Both are ROHS3 compliant and active products.

Lower Power Alternative: SMCJ60A and SMCJ60A-TP provide reduced current handling (15.5A) and power dissipation (1500W) with identical voltage ratings. These are suitable only for applications with lower transient energy requirements and are not recommended as direct replacements for the original 3000W specification.

Voltage Variant Caution: TPSMC62A and TPSMC68A have different voltage ratings (53V/85V and 58.1V/92V respectively) and do not meet the 60V standoff and 96.8V clamping requirements. These are not suitable substitutes for the CD214L-T60ALF.

Frequently Asked Questions (FAQ)

Q: Can SMCJ60A replace CD214L-T60ALF directly?

A: SMCJ60A matches the voltage specifications (60V standoff, 96.8V clamping) and package (DO-214AB, SMC) but has reduced peak pulse current (15.5A vs. 31A) and power dissipation (1500W vs. 3000W). It is suitable only for applications with lower transient energy requirements.

Q: What is the difference between SMLJ60A and SMDJ60A?

A: Both are direct electrical equivalents with identical voltage ratings, peak pulse current (31A), and power dissipation (3000W). SMLJ60A is manufactured by Bourns Inc. (original supplier), while SMDJ60A is manufactured by Alpha & Omega Semiconductor Inc. Both are active products with ROHS3 compliance.

Q: Why are 5.0SMDJ60A and 5.0SMDJ60A-T7 listed as substitutes?

A: These parts maintain the same voltage protection characteristics (60V standoff, 96.8V clamping) but provide higher peak pulse current (51.7A) and power dissipation (5000W). They are suitable when the application requires additional transient energy absorption capability beyond the original 3000W specification.

Q: Are TPSMC62A and TPSMC68A suitable replacements?

A: No. These parts have different voltage ratings (53V/85V and 58.1V/92V respectively) and do not meet the 60V standoff and 96.8V clamping voltage requirements of the CD214L-T60ALF. They are not compatible substitutes.

Q: What packaging options are available for substitutes?

A: All substitute parts use the DO-214AB (SMC) surface mount package, matching the original CD214L-T60ALF. Some variants are available in Tape & Reel (TR) packaging for automated assembly, while others are supplied in standard packaging. Verify packaging requirements with your procurement specification.

Q: Are all substitute parts ROHS3 compliant?

A: SMLJ60A, 5.0SMDJ60A, 5.0SMDJ60A-T7, SMCJ60A-TP, SMDJ60A, SMDJ60A-HR, TPSMC62A, and TPSMC68A are ROHS3 compliant. SMCJ60A (Fairchild Semiconductor) does not list RoHS status in the provided data. Verify compliance requirements for your application.

Q: What is the operating temperature range difference between substitutes?

A: Most substitutes operate within -55°C to 150°C, matching the original. However, 5.0SMDJ60A extends to -55°C to 175°C, 5.0SMDJ60A-T7 and SMDJ60A-HR support -65°C to 150°C, and SMCJ60A-TP extends to -55°C to 175°C. Select based on your application's thermal requirements.
