CD214B-T64CALF Equivalent & Substitute Parts

Part Overview

The CD214B-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 5.8A peak pulse current capability in a DO-214AA (SMB) package. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214B-T64CALF is determined by strict equivalence across the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 64V
• Voltage - Clamping (Max) @ Ipp: 103V
• Current - Peak Pulse (10/1000µs): 5.8A ± tolerance
• Package / Case: DO-214AA (SMB)
• Bidirectional Channels: 1
• Type: Zener

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8541.10.0080

Substitute parts are grouped into two categories: Direct Equivalents (matching all electrical specifications within tolerance) and Similar Parts (meeting core voltage and package requirements with minor parameter variations).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended Primary Substitutes):

SMBJ64CA (Meritek), SMBJ64CA-TP (Micro Commercial Co), and TV06B640JB-HF (Comchip Technology) are direct electrical equivalents to the CD214B-T64CALF. All three parts maintain identical voltage specifications (64V standoff, 103V clamping) and equivalent peak pulse current ratings (5.8A–5.83A). All substitute parts are active products with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and regulatory compliance.

SMBJ64CA-TP offers extended operating temperature range (-55°C to 175°C) compared to the original specification (-55°C to 150°C), providing additional thermal margin for demanding applications. This part is supplied in Tape & Reel packaging, suitable for automated assembly processes.

Similar Part (Alternative for Higher Voltage Applications):

SMBJ75CA (MDD) is classified as a similar part due to elevated voltage specifications (75V standoff, 121V clamping). This part is suitable only for applications where higher voltage transient suppression is acceptable or required. The reduced peak pulse current (5.3A versus 5.8A) must be evaluated against circuit protection requirements.

Compliance and Availability:

All substitute parts meet ROHS3 compliance, MSL 1 moisture sensitivity, and ECCN EAR99 export classification. Inventory availability is confirmed for all active alternatives, with SMBJ64CA offering the highest stock level (35,400 units).

Frequently Asked Questions (FAQ)

Q: Can SMBJ64CA directly replace CD214B-T64CALF in production?

A: Yes. SMBJ64CA is a direct electrical equivalent with identical voltage ratings (64V standoff, 103V clamping) and equivalent peak pulse current (5.83A). Both parts use DO-214AA (SMB) packaging and meet ROHS3 compliance. No circuit modifications are required.

Q: What is the difference between SMBJ64CA and SMBJ64CA-TP?

A: Both parts are electrically identical with 64V standoff and 103V clamping specifications. The primary difference is packaging: SMBJ64CA-TP is supplied in Tape & Reel format suitable for automated assembly, while standard SMBJ64CA packaging is not specified. SMBJ64CA-TP also offers extended operating temperature range (-55°C to 175°C versus -55°C to 150°C).

Q: Why is SMBJ75CA listed as a similar part rather than a direct equivalent?

A: SMBJ75CA has higher voltage specifications (75V standoff, 121V clamping versus 64V/103V) and lower peak pulse current (5.3A versus 5.8A). This part is suitable only for applications requiring higher voltage transient suppression. Direct substitution in circuits designed for 64V/103V operation is not recommended without circuit analysis.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (SMBJ64CA, SMBJ64CA-TP, TV06B640JB-HF, and SMBJ75CA) are ROHS3 compliant with MSL 1 moisture sensitivity rating, matching the original CD214B-T64CALF specification.

Q: What is the operating temperature range for TV06B640JB-HF?

A: Operating temperature range for TV06B640JB-HF is not specified in the provided data. For applications with strict temperature requirements, SMBJ64CA-TP (-55°C to 175°C) or SMBJ64CA (-55°C to 150°C) are recommended alternatives.

Q: Can I use these substitute parts in both through-hole and surface mount designs?

A: All substitute parts are surface mount components in DO-214AA (SMB) package format. They are not suitable for through-hole applications. PCB layout and assembly processes must be designed for surface mount technology.
