CD214A-T14CALF Equivalent & Substitute Parts

Part Overview

The CD214A-T14CALF is a bidirectional transient voltage suppressor (TVS) diode manufactured by Bourns Inc., rated for 14V reverse standoff with 23.2V maximum clamping voltage and 17.2A peak pulse current in a surface mount DO-214AC (SMA) package. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part is ROHS3 compliant with unlimited moisture sensitivity rating, suitable for general-purpose transient protection applications across industrial and consumer electronics.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214A-T14CALF is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 14V
• Voltage - Clamping (Max) @ Ipp: 23.2V
• Current - Peak Pulse (10/1000µs): 17.2A
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC (SMA)
• Mounting Type: Surface Mount
• Bidirectional Channels: 1

Substitute parts are categorized into two groups:

Direct Equivalents maintain identical electrical specifications across all critical parameters. These parts provide one-to-one functional replacement with no circuit redesign required.

Similar Alternatives share the same package, mounting type, and power rating but operate at different voltage levels (12V or 13V standoff). These parts are suitable only when circuit voltage requirements permit operation at the alternative voltage rating.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended for Drop-In Replacement)

SMAJ14CA (Good-Ark Semiconductor) and SMAJ14CA-TP (Micro Commercial Co) are direct electrical equivalents to the CD214A-T14CALF. Both parts maintain identical voltage ratings (14V standoff, 23.2V clamping), current specifications (17.2A peak pulse), and power dissipation (400W). Both are ROHS3 compliant with active product status, ensuring long-term availability and supply chain stability. SMAJ14CA-TP offers extended operating temperature range to 175°C, providing additional thermal margin in high-temperature applications.

Similar Alternatives (Voltage-Dependent Selection)

SMAJ13CA-TP (Micro Commercial Co) operates at 13V standoff with 21.5V clamping voltage. This part is suitable only for circuits where the protected voltage rail is 13V or lower. The extended temperature range to 175°C and higher peak pulse current (18.6A) may provide operational advantages in specific thermal environments.

SMAJ12CA-M3/61 and SMAJ12CA-M3/5A (Vishay General Semiconductor) operate at 12V standoff with 19.9V clamping voltage. These parts are applicable only to 12V protection circuits. Both variants share identical electrical specifications and are available in active status with ROHS3 compliance.

Compliance and Availability

All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), matching the original part's environmental specifications. Active product status across all recommended substitutes ensures procurement reliability and eliminates obsolescence risk associated with the original CD214A-T14CALF.

Frequently Asked Questions (FAQ)

Q: Can SMAJ14CA directly replace CD214A-T14CALF without circuit modification?

A: Yes. SMAJ14CA maintains identical electrical specifications across all critical parameters: 14V reverse standoff, 23.2V clamping voltage, 17.2A peak pulse current, and 400W power dissipation. The DO-214AC (SMA) package and surface mount configuration are identical. No circuit redesign is required.

Q: What is the difference between SMAJ14CA and SMAJ14CA-TP?

A: Both parts are electrically identical with 14V standoff and 23.2V clamping specifications. The primary difference is operating temperature range: SMAJ14CA operates to 150°C (TJ), while SMAJ14CA-TP extends to 175°C (TA). SMAJ14CA-TP is preferred for applications with elevated ambient or junction temperatures.

Q: Can I use SMAJ13CA-TP or SMAJ12CA in place of CD214A-T14CALF?

A: Only if your circuit protection voltage requirement is 13V or 12V respectively. These parts operate at lower voltage ratings and will clamp at lower voltages (21.5V for 13V part, 19.9V for 12V part). Using a lower-voltage TVS on a 14V circuit will result in premature clamping and potential component failure. Voltage compatibility is mandatory.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All recommended substitute parts maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, matching the original CD214A-T14CALF specifications.

Q: What is the inventory status of substitute parts?

A: SMAJ14CA (Good-Ark) has 65,400 units in stock. SMAJ14CA-TP (MCC) has 15,641 units available. SMAJ13CA-TP (MCC) has 10,300 units. SMAJ12CA-M3/61 (Vishay) has 783 units, and SMAJ12CA-M3/5A (Vishay) has 1,006 units. Direct equivalents (14V parts) offer superior availability.

Q: Does package type affect substitution compatibility?

A: No. All substitute parts use the same DO-214AC (SMA) surface mount package as the original CD214A-T14CALF. PCB footprint and assembly process remain unchanged.
