CD214A-T160CALF Equivalent & Substitute Parts

Part Overview

The CD214A-T160CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 160V reverse standoff voltage with a 259V maximum clamping voltage and 1.5A peak pulse current capability in a DO-214AC (SMA) package. The part is currently classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214A-T160CALF is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 160V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 259V (exact match required)
• Package / Case: DO-214AC (SMA) (exact match required)
• Current - Peak Pulse: 1.5A minimum (equal or greater acceptable)
• Power - Peak Pulse: 400W (exact match required)
• Type: Zener, Bidirectional, single channel (exact match required)

Substitute parts are grouped into two categories: direct equivalents (identical specifications) and similar alternatives (minor parameter variations within acceptable tolerance).

Parameter Comparison

Engineering Selection Recommendations

SMAJ160CA (Meritek) is a direct functional equivalent with active product status. All critical electrical parameters match the CD214A-T160CALF specification. The peak pulse current is marginally higher at 1.54A versus 1.5A, which is within acceptable tolerance for this component class. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) are maintained. This part is available in high inventory (25,400 pcs) and is suitable for direct substitution.

SMAJ160CA-TP (Micro Commercial Co) is a direct equivalent with identical peak pulse current (1.5A) and all critical voltage parameters. This part offers an extended operating temperature range (-55°C ~ 175°C) compared to the original specification (-55°C ~ 150°C), providing additional thermal margin. Active product status and ROHS3 compliance are confirmed. Inventory availability is lower (1,315 pcs) but sufficient for most applications.

Both substitute parts maintain electrical and mechanical compatibility with the original CD214A-T160CALF and are suitable for direct PCB replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can SMAJ160CA replace CD214A-T160CALF directly on the PCB?

A: Yes. Both parts use identical DO-214AC (SMA) packaging and have matching pinout configuration. No PCB layout changes are required.

Q: What is the significance of the 1.54A peak pulse current in SMAJ160CA versus 1.5A in the original?

A: The 1.54A specification in SMAJ160CA exceeds the minimum requirement and provides additional transient current handling capability. This is acceptable for substitution as it meets or exceeds the original specification.

Q: Why is the CD214A-T160CALF marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Bourns Inc. Active alternatives such as SMAJ160CA and SMAJ160CA-TP are recommended for new designs and ongoing procurement.

Q: Are there any compliance differences between the substitute parts?

A: All three parts are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity. SMAJ160CA-TP offers an extended operating temperature range (-55°C ~ 175°C) compared to the original (-55°C ~ 150°C), which may be advantageous in high-temperature applications.

Q: Which substitute part should be selected for new designs?

A: Either SMAJ160CA or SMAJ160CA-TP is acceptable. Selection should be based on inventory availability, lead time, and thermal requirements of the specific application. SMAJ160CA offers higher inventory availability, while SMAJ160CA-TP provides extended temperature range.

Q: Do the substitute parts require any circuit design changes?

A: No. All critical electrical parameters (voltage ratings, clamping characteristics, peak pulse power) are identical or superior to the original specification. No circuit modifications are necessary.
