CD214C-T160ALF Equivalent & Substitute Parts
Part Overview
The CD214C-T160ALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., classified as an obsolete product. This unidirectional Zener diode is designed for general-purpose transient voltage suppression in surface mount applications using the DO-214AB (SMC) package. The 160V reverse standoff voltage with 259V maximum clamping voltage and 5.8A peak pulse current rating provides protection in standard industrial and commercial circuits. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation
Substitution of the CD214C-T160ALF is determined by strict electrical and mechanical parameter matching within the TVS diode category. The critical parameters that define substitutability are:
Electrical Parameters: Voltage - Reverse Standoff (160V), Voltage - Breakdown (178V minimum), Voltage - Clamping (259V maximum), Current - Peak Pulse (5.8A), and Power - Peak Pulse (1500W).
Mechanical Parameters: Package / Case (DO-214AB, SMC) and Mounting Type (Surface Mount).
Environmental Parameters: Operating Temperature range and RoHS compliance status.
Substitute parts are grouped into two categories:
Direct Equivalents: Parts with identical electrical specifications (5.8A peak pulse current, 1500W peak pulse power) and matching package specifications. These include SMCJ160A from Fairchild Semiconductor, SMCJ160A-HR, SMCJ160A-HRA, and SMCJ160A-HRAT7 from Littelfuse Inc., and SMCJ160A-TP from Micro Commercial Co.

Frequently Asked Questions (FAQ)
Q: Can SMCJ160A directly replace CD214C-T160ALF?
A: Yes. SMCJ160A from Fairchild Semiconductor is a direct electrical equivalent with identical voltage ratings (160V reverse standoff, 259V clamping), current rating (5.8A peak pulse), power rating (1500W), and DO-214AB package. Both are unidirectional Zener TVS diodes with single channel configuration.
Q: What is the difference between direct equivalents and similar alternatives?
A: Direct equivalents (SMCJ160A variants, SMCJ160A-TP) maintain the original 5.8A peak pulse current and 1500W power rating. Similar alternatives (5.0SMDJ160A series, SMDJ160A) provide higher current and power ratings (11.6A to 19.3A, 3000W to 5000W) while maintaining identical voltage specifications. Similar alternatives offer enhanced transient suppression capability for the same voltage protection level.
Q: Are all substitute parts in the same package?
A: Yes. All substitute parts use the DO-214AB (SMC) surface mount package, ensuring mechanical and thermal compatibility with the original CD214C-T160ALF footprint and assembly process.
Q: What is the operating temperature range difference?
A: The original CD214C-T160ALF operates from -55°C to 150°C. Littelfuse variants (SMCJ160A-HR, SMCJ160A-HRA, SMCJ160A-HRAT7) and 5.0SMDJ160A-T7 extend the lower limit to -65°C. SMCJ160A-TP extends the upper limit to 175°C. These extended ranges provide flexibility for applications with more demanding thermal requirements.
Q: Are all substitute parts RoHS compliant?
A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the original CD214C-T160ALF. All maintain MSL 1 (Unlimited) moisture sensitivity level.
Q: Which substitute should I select for new designs?
A: For direct replacement with identical specifications, select SMCJ160A-HRAT7 from Littelfuse Inc. or SMCJ160A-TP from Micro Commercial Co., both offering active product status and extended operating temperature ranges. For applications requiring enhanced transient energy absorption, select 5.0SMDJ160A-T7 from Littelfuse Inc. or SMDJ160A from Alpha & Omega Semiconductor Inc.
