CD214L-T5.0CALF Equivalent & Substitute Parts

Part Overview

The CD214L-T5.0CALF is a 5V Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 9.2V maximum clamping voltage and 326A peak pulse current capability in a DO-214AB (SMC) package. The part is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD214L-T5.0CALF is determined by the following critical parameters:

• Voltage - Reverse Standoff: 5V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 9.2V (exact match required)
• Voltage - Breakdown (Min): 6.4V (exact match required)
• Package / Case: DO-214AB, SMC (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Zener, Bidirectional (exact match required)

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

Category A - Full Performance Match (326A / 3000W): Parts with identical peak pulse current and power ratings to the original component.

Category B - Reduced Performance (163A-171A / 1500W): Parts with lower peak pulse current and power dissipation ratings. These parts maintain voltage specifications but offer reduced transient energy handling capability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Full Performance Match):

SMLJ5.0CA from Bourns Inc. is the direct equivalent replacement. This part maintains identical electrical specifications (326A peak pulse current, 3000W power dissipation) and operating temperature range (-55°C ~ 150°C). As an active product from the original manufacturer, it provides continuity in design and procurement. ROHS3 compliance and MSL 1 rating match the original specification.

SMDJ5.0CA from Alpha & Omega Semiconductor Inc. provides equivalent performance with 326.1A peak pulse current and 3000W power dissipation. This part is suitable for applications requiring full transient energy handling capability matching the original design.

Secondary Substitutes (Reduced Performance):

SMCJ5.0CA, SMCJ5.0CA-TP, SMCJ5V0CA, and TV15C5V0JB-HF are suitable for applications where peak pulse current can be reduced to 163A-171A and power dissipation to 1500W. These parts maintain the critical voltage specifications (5V standoff, 9.2V clamping) and DO-214AB package compatibility. Selection among these options depends on packaging requirements (Tape & Reel vs. Cut Tape) and operating temperature range needs.

All substitute parts are active products with ROHS3 compliance, ensuring regulatory alignment and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can SMCJ5.0CA be used as a direct replacement for CD214L-T5.0CALF?

A: SMCJ5.0CA maintains identical voltage specifications and package format but has reduced peak pulse current (171A vs. 326A) and power dissipation (1500W vs. 3000W). It is suitable only for applications where transient energy levels do not exceed 1500W.

Q: What is the difference between Category A and Category B substitutes?

A: Category A substitutes (SMLJ5.0CA, SMDJ5.0CA) provide full performance matching with 326A peak pulse current and 3000W power dissipation. Category B substitutes provide reduced performance with 163A-171A peak pulse current and 1500W power dissipation. Selection depends on the transient energy requirements of the application.

Q: Are all substitute parts available in the same packaging options?

A: Packaging varies by manufacturer. SMLJ5.0CA is available in Tape & Reel. SMCJ5.0CA is available in Cut Tape & Digi-Reel. SMCJ5.0CA-TP is available in Tape & Reel. Verify packaging availability with your supplier for procurement requirements.

Q: Do all substitutes meet the same compliance standards?

A: All listed substitutes are ROHS3 compliant. REACH status varies: Bourns parts are REACH Affected; Taiwan Semiconductor Corporation, Micro Commercial Co, Alpha & Omega Semiconductor Inc., and Comchip Technology parts are REACH Unaffected. Verify REACH compliance requirements for your application and region.

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

A: SMLJ5.0CA, SMDJ5.0CA, SMCJ5.0CA, and TV15C5V0JB-HF operate from -55°C to 150°C. SMCJ5.0CA-TP extends to -55°C to 175°C. SMCJ5V0CA does not specify an operating temperature range. Confirm temperature requirements for your application environment.

Q: Can I use SMCJ5V0CA if operating temperature is not specified?

A: Operating temperature range is a critical design parameter. Use SMCJ5V0CA only if your application does not require temperature specification confirmation or if you obtain this information directly from the manufacturer.
