CD214A-T64CALF Equivalent & Substitute Parts

Part Overview

The CD214A-T64CALF 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 64V reverse standoff voltage with 103V maximum clamping voltage and 3.9A peak pulse current capability in a DO-214AC (SMA) package. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD214A-T64CALF is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 64V
• Voltage - Clamping (Max) @ Ipp: 103V
• Current - Peak Pulse (10/1000µs): 3.9A (±tolerance acceptable)
• Package / Case: DO-214AC (SMA)
• Mounting Type: Surface Mount
• Type: Zener, Bidirectional

Substitute parts are grouped into two categories:

Direct Substitutes: Parts meeting all critical electrical parameters (64V standoff, 103V clamping, 3.9A peak pulse) with identical package specifications.

Similar Substitutes: Parts with different voltage ratings (75V standoff, 121V clamping) that share the same package and mounting type but operate in a different voltage class. These are suitable only when circuit design permits higher voltage operation.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Electrical Equivalents):

SMAJ64CA (Meritek) and SMAJ64CA-TP (Micro Commercial Co) are direct electrical equivalents to the CD214A-T64CALF. Both maintain the 64V reverse standoff voltage, 103V clamping voltage, and equivalent peak pulse current specifications. Both manufacturers provide active product status with ROHS3 compliance. SMAJ64CA-TP offers extended operating temperature range (-55°C ~ 175°C) compared to the original part, providing additional thermal margin in high-temperature applications.

Alternative Substitute (Higher Voltage Class):

SMAJ75CA-M3/5A (Vishay) operates at a higher voltage class (75V standoff, 121V clamping) and is suitable only when circuit design specifications permit operation at elevated voltage levels. This part is not a direct replacement but may be considered for applications with flexible voltage requirements.

All substitute options maintain DO-214AC (SMA) package compatibility, surface-mount configuration, and ROHS3 compliance status, ensuring compatibility with existing PCB designs and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SMAJ64CA directly replace CD214A-T64CALF in existing designs?

A: Yes. SMAJ64CA maintains identical voltage ratings (64V standoff, 103V clamping) and equivalent peak pulse current (3.88A vs. 3.9A). Both use DO-214AC (SMA) packaging and are ROHS3 compliant. No circuit modifications are required.

Q: What is the difference between SMAJ64CA and SMAJ64CA-TP?

A: Both parts share identical electrical specifications (64V standoff, 103V clamping, 3.9A peak pulse). SMAJ64CA-TP is supplied in Tape & Reel packaging and features an extended operating temperature range (-55°C ~ 175°C) compared to standard specifications (-55°C ~ 150°C). Select SMAJ64CA-TP for high-temperature environments or when tape-and-reel packaging is required for automated assembly.

Q: Is SMAJ75CA-M3/5A a suitable replacement?

A: SMAJ75CA-M3/5A is not a direct replacement. It operates at a higher voltage class (75V standoff, 121V clamping) with lower peak pulse current (3.3A). Use this part only if circuit design permits operation at elevated voltage levels. Verify that the higher clamping voltage does not exceed downstream component ratings.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. CD214A-T64CALF, SMAJ64CA, SMAJ64CA-TP, and SMAJ75CA-M3/5A are all ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What packaging options are available?

A: SMAJ64CA is available in standard packaging. SMAJ64CA-TP is supplied in Tape & Reel (TR) format for automated assembly processes. All parts use DO-214AC (SMA) surface-mount package configuration.
