CD214L-T14CALF Equivalent & Substitute Parts

Part Overview

The CD214L-T14CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., rated for 14V reverse standoff with 23.2V maximum clamping voltage and 129.4A peak pulse current. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain identical electrical characteristics and mechanical compatibility within the DO-214AB (SMC) package format.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: reverse standoff voltage (14V), breakdown voltage minimum (15.6V), clamping voltage maximum (23.2V), package format (DO-214AB/SMC), mounting type (surface mount), and bidirectional single-channel configuration. Parts are categorized as direct substitutes when all electrical parameters and package specifications match exactly. Similar substitutes are identified where voltage and clamping characteristics remain identical but peak pulse current or power dissipation ratings differ, indicating enhanced or reduced surge handling capability within the same voltage class.

Engineering Selection Recommendations

SMLJ14CA (Bourns Inc.) and SMDJ14CA (Alpha & Omega Semiconductor Inc.) are direct electrical and mechanical equivalents to the obsolete CD214L-T14CALF, maintaining identical peak pulse current (129.4A) and power dissipation (3000W) specifications. Both parts are active products with ROHS3 compliance and full temperature range compatibility (-55°C to 150°C).

TV30C140JB-G (Comchip Technology) provides equivalent performance with marginally lower peak pulse current (129.31A), remaining within the same power class and voltage specifications. This part is active and ROHS3 compliant.

5.0SMDJ14CA (MDE Semiconductor Inc.) and 5.0SMDJ14CA-T7 (Littelfuse Inc.) offer enhanced surge handling with 216A peak pulse current and 5000W power dissipation while maintaining identical voltage characteristics. The Littelfuse variant extends the lower operating temperature limit to -65°C. These parts are suitable for applications requiring higher transient energy absorption.

SMCJ14CA (Meritek) and SMCJ14CA-TP (Micro Commercial Co) provide reduced surge capacity (64.66A to 64.7A, 1500W) within the same voltage class. SMCJ14CA-TP offers extended upper temperature rating to 175°C. These variants are appropriate for lower-energy transient environments.

Frequently Asked Questions (FAQ)

Q: Can SMLJ14CA directly replace CD214L-T14CALF without circuit modification?

A: Yes. SMLJ14CA matches all critical electrical parameters: 14V reverse standoff, 15.6V minimum breakdown, 23.2V maximum clamping, and 129.4A peak pulse current. Both use DO-214AB (SMC) packaging and operate across -55°C to 150°C. No design changes are required.

Q: What is the difference between direct substitutes and similar substitutes?

A: Direct substitutes (SMLJ14CA, TV30C140JB-G, SMDJ14CA) maintain identical peak pulse current and power dissipation ratings. Similar substitutes differ in surge handling capacity: 5.0SMDJ14CA series provides 216A/5000W (enhanced), while SMCJ14CA series provides 64.66A/1500W (reduced). Voltage specifications remain constant across all variants.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original CD214L-T14CALF specification.

Q: Can I use 5.0SMDJ14CA-T7 in applications requiring -55°C minimum temperature?

A: Yes. The 5.0SMDJ14CA-T7 operates from -65°C to 150°C, exceeding the -55°C to 150°C range of the original part. Extended lower temperature capability provides additional operational margin.

Q: Which substitute offers the highest temperature rating?

A: SMCJ14CA-TP (Micro Commercial Co) provides the highest upper temperature limit at 175°C, compared to 150°C for most alternatives. This variant is suitable for high-temperature environments while maintaining 14V voltage class specifications.

Q: Do all substitutes use the same DO-214AB package?

A: Yes. All substitute parts use DO-214AB (SMC) surface mount packaging, ensuring mechanical and footprint compatibility with the original CD214L-T14CALF design.
