CD214L-T9.0CALF Equivalent & Substitute Parts

Part Overview

The CD214L-T9.0CALF 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 9V reverse standoff voltage, 15.4V maximum clamping voltage, and 194.8A peak pulse current capability in a DO-214AB (SMC) package. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214L-T9.0CALF is determined by the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff: 9V (±tolerance)
• Voltage - Clamping (Max) @ Ipp: 15.4V
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

Substitute parts are grouped into two categories:

Direct Substitutes maintain identical electrical specifications and peak pulse current ratings (194.8A, 3000W). These parts are pin-compatible and functionally equivalent with no design modifications required.

Similar Substitutes maintain the same voltage ratings and package but differ in peak pulse current (ranging from 97.4A to 194.9A) and power dissipation (1500W to 3000W). Selection depends on circuit peak pulse current requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Recommended for Obsolete Part Replacement):

SMLJ9.0CA (Bourns Inc.) is the primary recommended substitute. It maintains identical electrical specifications and peak pulse current ratings while offering active product status and ROHS3 compliance. This part provides continuity with the original manufacturer.

SMDJ9.0CA-HR, SMDJ9.0CA-HRA, and SMDJ9.0CA-HRAT7 (Littelfuse Inc.) are functionally equivalent alternatives with extended lower operating temperature range (-65°C vs. -55°C). These parts are suitable for applications requiring enhanced cold-temperature performance.

SMDJ9.0CA (Alpha & Omega Semiconductor Inc.) provides equivalent electrical performance with active product status and ROHS3 compliance.

Similar Substitutes (For Lower Peak Pulse Current Applications):

SMCJ9.0CA (Taiwan Semiconductor Corporation), SMCJ9.0CA-TP (Micro Commercial Co), and SMCJ9V0CA (Fairchild Semiconductor) are suitable only for applications where peak pulse current does not exceed 102A and power dissipation does not exceed 1500W. These parts share identical voltage ratings and package configuration but provide reduced current handling capability.

All substitute parts maintain ROHS3 compliance and are classified as active products, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can SMCJ9.0CA be used as a direct replacement for CD214L-T9.0CALF?

A: SMCJ9.0CA is a similar substitute, not a direct replacement. While it maintains the same 9V reverse standoff voltage, 15.4V clamping voltage, and DO-214AB package, it has reduced peak pulse current (102A vs. 194.8A) and power dissipation (1500W vs. 3000W). Use this part only if your circuit peak pulse current does not exceed 102A.

Q: What is the difference between SMDJ9.0CA-HR and SMDJ9.0CA-HRA?

A: Both parts are manufactured by Littelfuse Inc. and maintain identical electrical specifications (9V standoff, 15.4V clamping, 194.8A peak pulse, 3000W power). The difference lies in the series designation (SMDJ-HR vs. SMDJ-HRA) and internal design variants. Both are functionally equivalent for the CD214L-T9.0CALF application.

Q: Why does SMDJ9.0CA-HRAT7 have a different part number suffix?

A: The "T7" suffix indicates a specific tape configuration or manufacturing date code variant. The electrical specifications and functional performance remain identical to SMDJ9.0CA-HR and SMDJ9.0CA-HRA. This part is suitable for automated assembly processes using standard tape-and-reel packaging.

Q: Is the extended temperature range of SMDJ9.0CA-HR (-65°C to 150°C) compatible with CD214L-T9.0CALF applications?

A: Yes. The extended lower temperature limit (-65°C vs. -55°C) is a superset of the original part's operating range. SMDJ9.0CA-HR can be used in any application designed for CD214L-T9.0CALF without thermal performance concerns.

Q: Can I use SMCJ9.0CA-TP in a high-current transient protection circuit?

A: SMCJ9.0CA-TP is limited to 97.4A peak pulse current and 1500W power dissipation. If your circuit experiences transient pulses exceeding these values, use a direct substitute (SMLJ9.0CA, SMDJ9.0CA-HR, SMDJ9.0CA-HRA, SMDJ9.0CA-HRAT7, or SMDJ9.0CA) rated for 194.8A or higher.

Q: Are all substitute parts ROHS3 compliant?

A: All direct substitutes and most similar substitutes are ROHS3 compliant. SMCJ9V0CA (Fairchild Semiconductor) does not specify RoHS status in the provided data. Verify compliance requirements with your procurement or quality assurance department before selection.

Q: What packaging options are available for these substitutes?

A: All substitute parts use the DO-214AB (SMC) surface-mount package, maintaining mechanical compatibility with CD214L-T9.0CALF. Packaging formats vary (Tape & Reel, Bulk) but do not affect electrical performance or PCB footprint.
