CD214A-T7.5CALF Equivalent & Substitute Parts

Part Overview

The CD214A-T7.5CALF 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 7.5V reverse standoff voltage with a 12.9V maximum clamping voltage and 31A peak pulse current capability in a DO-214AC (SMA) package. The part is currently obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the CD214A-T7.5CALF is determined by the following critical parameters:

Voltage - Reverse Standoff (Typ): 7.5V
Voltage - Clamping (Max) @ Ipp: 12.9V
Current - Peak Pulse (10/1000µs): 31A
Package / Case: DO-214AC, SMA
Type: Zener, Bidirectional, single channel

Substitute parts are grouped into two categories:

Direct Equivalents: Parts with identical electrical specifications (7.5V standoff, 12.9V clamping, 31A peak pulse) and active product status.

Similar Alternatives: Parts with comparable but not identical electrical specifications that may serve the same protective function in general-purpose applications, with variations in standoff voltage or clamping voltage within the same package family.

Engineering Selection Recommendations

Direct Equivalents (Recommended Primary Choices):

SMAJ7.5CA (MDD) and SMAJ7.5CA-TP (Micro Commercial Co) are direct electrical equivalents with identical standoff voltage (7.5V), clamping voltage (12.9V), and peak pulse current (31A). Both are active products with ROHS3 compliance. SMAJ7.5CA-TP offers extended operating temperature range (-55°C ~ 175°C) compared to the original part. MDD's SMAJ7.5CA maintains the original temperature specification (-50°C ~ 150°C). Both are available in DO-214AC (SMA) package.

Similar Alternatives (Application-Dependent):

SMAJ8.0CA-M3/61 (Vishay) features a higher standoff voltage (8V) and clamping voltage (13.6V) with slightly reduced peak pulse current (29.4A). This part is suitable for applications requiring higher voltage protection margins.

SMAJ9.0CA-TP (Micro Commercial Co) features the highest standoff voltage (9V) and clamping voltage (15.4V) with the lowest peak pulse current (26A). This part is suitable for applications with higher voltage transients but lower current requirements.

All substitute parts maintain ROHS3 compliance and the same DO-214AC (SMA) surface-mount package, ensuring mechanical and thermal compatibility.

Frequently Asked Questions (FAQ)

Q: Can SMAJ7.5CA directly replace CD214A-T7.5CALF?

A: Yes. SMAJ7.5CA (MDD) is a direct electrical equivalent with identical voltage and current specifications. Both parts feature 7.5V reverse standoff voltage, 12.9V clamping voltage, and 31A peak pulse current in DO-214AC (SMA) package. The primary difference is product status: CD214A-T7.5CALF is obsolete while SMAJ7.5CA is active.

Q: What is the difference between SMAJ7.5CA and SMAJ7.5CA-TP?

A: Both are direct electrical equivalents with identical voltage and current ratings. The primary difference is operating temperature range: SMAJ7.5CA-TP extends to 175°C (TA) compared to SMAJ7.5CA at 150°C (TJ). SMAJ7.5CA-TP is supplied in Tape & Reel packaging, while SMAJ7.5CA is supplied in bulk.

Q: Can SMAJ8.0CA-M3/61 or SMAJ9.0CA-TP be used as substitutes?

A: These parts are similar alternatives, not direct equivalents. SMAJ8.0CA-M3/61 has higher voltage ratings (8V standoff, 13.6V clamping) and slightly lower peak pulse current (29.4A). SMAJ9.0CA-TP has the highest voltage ratings (9V standoff, 15.4V clamping) with the lowest peak pulse current (26A). Use these only if your application requires higher voltage protection and can tolerate the specified current and voltage deviations.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use DO-214AC (SMA) surface-mount package, ensuring mechanical and thermal compatibility with the original CD214A-T7.5CALF design.

Q: What compliance certifications apply to these parts?

A: SMAJ7.5CA, SMAJ7.5CA-TP, and SMAJ8.0CA-M3/61 are ROHS3 compliant. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts.
