CD214C-T16ALF Equivalent & Substitute Parts

Part Overview

The CD214C-T16ALF is a 16V Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., rated for 26V clamping voltage and 57.7A peak pulse current in a DO-214AB (SMC) surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

TVS diodes in this voltage and power class are used for general-purpose transient protection in electronic circuits. The CD214C-T16ALF's electrical characteristics define a specific performance envelope that substitute parts must match or exceed within acceptable tolerances.

Substitute Part Grouping Explanation

Substitute parts for the CD214C-T16ALF are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes (Electrical & Package Match) Parts meeting all critical electrical parameters and using the same DO-214AB (SMC) package footprint:

Voltage - Reverse Standoff: 16V
Voltage - Clamping (Max) @ Ipp: 26V
Current - Peak Pulse: 57.7A
Power - Peak Pulse: 1500W
Package: DO-214AB, SMC

Similar Substitutes (Electrical Match, Higher Performance) Parts matching voltage specifications and clamping characteristics but with higher peak pulse current and power ratings, or alternative package configurations:

Voltage - Reverse Standoff: 16V
Voltage - Clamping (Max) @ Ipp: 26V
Current - Peak Pulse: ≥57.7A (higher ratings acceptable)
Power - Peak Pulse: ≥1500W (higher ratings acceptable)
Package: DO-214AB (SMC) or DO-214AC (SMA)

Engineering Selection Recommendations

For Direct Replacement (Same Electrical & Package Specifications)

SMCJ16A-HR, SMCJ16A-HRA, SMCJ16A-HRAT7, and SMCJ16A-TP are direct electrical and mechanical equivalents to the CD214C-T16ALF. All maintain 16V standoff voltage, 26V clamping voltage, 57.7A peak pulse current, and 1500W peak pulse power in the DO-214AB (SMC) package. All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) ratings. These parts are in active production status, ensuring long-term availability.

For Enhanced Performance (Higher Current/Power Capability)

5.0SMDJ16A and 5.0SMDJ16A-T7 provide higher peak pulse current (193A) and power dissipation (5000W) while maintaining identical voltage specifications and DO-214AB (SMC) package compatibility. These parts are suitable for applications requiring additional transient protection margin. Both are ROHS3 compliant and in active production.

SMDJ16A offers 115.4A peak pulse current and 3000W power dissipation, positioning it between standard and high-power options. This part is also ROHS3 compliant and actively manufactured.

Package Consideration

SMCJ16A from EVVO Semi uses DO-214AC (SMA) package instead of DO-214AB (SMC). While electrically equivalent, this package change requires PCB layout modification and is not a direct drop-in replacement.

Frequently Asked Questions (FAQ)

Q: Can SMCJ16A-HR replace CD214C-T16ALF directly on the PCB?

A: Yes. SMCJ16A-HR matches all electrical parameters (16V standoff, 26V clamping, 57.7A peak pulse, 1500W power) and uses the identical DO-214AB (SMC) package. It is a direct mechanical and electrical substitute.

Q: What is the difference between SMCJ16A-HR, SMCJ16A-HRA, and SMCJ16A-HRAT7?

A: All three parts share identical electrical specifications and package type. The suffix designations indicate different manufacturing series or tape/reel configurations. Electrically, they are equivalent for circuit design purposes.

Q: Why would I choose 5.0SMDJ16A over SMCJ16A-HR?

A: 5.0SMDJ16A provides higher peak pulse current (193A vs. 57.7A) and power dissipation (5000W vs. 1500W). Selection depends on transient protection margin requirements. Both maintain the same voltage specifications and DO-214AB package footprint.

Q: Is SMCJ16A from EVVO Semi a direct replacement?

A: SMCJ16A is electrically equivalent but uses DO-214AC (SMA) package instead of DO-214AB (SMC). This package difference requires PCB layout modification and is not a direct drop-in replacement without redesign.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the original CD214C-T16ALF.

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

A: CD214C-T16ALF operates -55°C to 150°C. Most Littelfuse substitutes extend the lower limit to -65°C. SMCJ16A-TP and 5.0SMDJ16A extend the upper limit to 175°C. Application requirements determine whether extended temperature ranges are necessary.
