CD214A-T110CALF Equivalent & Substitute Parts

Part Overview

The CD214A-T110CALF 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 110V reverse standoff voltage with 177V maximum clamping voltage and 2.3A peak pulse current capability in a DO-214AC (SMA) package. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD214A-T110CALF is determined by the following critical parameters:

Direct Equivalents match all electrical specifications:

• Voltage - Reverse Standoff (Typ): 110V
• Voltage - Breakdown (Min): 122V
• Voltage - Clamping (Max) @ Ipp: 177V
• Current - Peak Pulse (10/1000µs): 2.3A (±tolerance acceptable)
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC (SMA)
• Operating Temperature Range: -55°C minimum to 150°C minimum

Similar Alternatives maintain functional compatibility within the same voltage class but with reduced current handling:

• Voltage - Reverse Standoff (Typ): 100V (lower voltage rating)
• Voltage - Clamping (Max) @ Ipp: 162V (lower clamping voltage)
• Current - Peak Pulse (10/1000µs): 1.9A (reduced current capacity)
• Power - Peak Pulse: 300W (reduced power dissipation)
• Package / Case: DO-214AC (SMA)

All substitute parts maintain identical package geometry, mounting type, and RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended Primary Choices):

SMAJ110CA (Meritek) and SMAJ110CA-TP (Micro Commercial Co) are functionally equivalent to the CD214A-T110CALF. Both maintain identical voltage ratings (110V standoff, 177V clamping), equivalent peak pulse current (2.26A and 2.3A respectively), and 400W power dissipation. Both are active products with ROHS3 compliance and unlimited moisture sensitivity rating. SMAJ110CA-TP offers extended operating temperature range to 175°C, providing additional thermal margin in high-temperature applications.

Similar Alternatives (Secondary Choices):

SMAJ100CA-M3/5A and SMAJ100CA-M3/61 (both Vishay TransZorb® series) operate at a lower voltage class (100V standoff, 162V clamping) with reduced peak pulse current (1.9A) and power dissipation (300W). These parts are suitable only for applications where the lower voltage rating and reduced current capacity do not compromise circuit protection requirements. Both are active products with ROHS3 compliance.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original part. Moisture sensitivity level remains at MSL 1 (Unlimited) across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can SMAJ110CA directly replace CD214A-T110CALF in existing designs?

A: Yes. SMAJ110CA matches all critical electrical parameters: 110V reverse standoff voltage, 177V clamping voltage, 2.3A peak pulse current, and 400W power dissipation. The DO-214AC (SMA) package geometry is identical, enabling direct PCB footprint compatibility without layout modifications.

Q: What is the difference between SMAJ110CA and SMAJ110CA-TP?

A: Both parts are electrically identical with matching voltage and current ratings. The primary difference is operating temperature range: SMAJ110CA operates to 150°C, while SMAJ110CA-TP extends to 175°C. SMAJ110CA-TP is manufactured by Micro Commercial Co, whereas SMAJ110CA is from Meritek. Selection depends on thermal environment requirements.

Q: Can SMAJ100CA-M3/5A be used as a substitute?

A: SMAJ100CA-M3/5A is a similar but not equivalent part. It operates at 100V standoff voltage (versus 110V) with 162V clamping voltage (versus 177V) and 1.9A peak pulse current (versus 2.3A). This part is suitable only if circuit protection requirements can tolerate the lower voltage ratings and reduced current handling capacity. Applications requiring full 110V/177V protection must use direct equivalents.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status identical to the original CD214A-T110CALF, ensuring regulatory compatibility for applications subject to RoHS requirements.

Q: What inventory considerations apply to these substitutes?

A: SMAJ110CA-TP offers the highest inventory availability (5909 pcs), followed by SMAJ110CA (300400 pcs). The original CD214A-T110CALF, being obsolete, has limited remaining inventory (988 pcs). For new designs and long-term supply assurance, direct equivalents from active product lines are recommended.

Q: Do package dimensions differ between substitute parts?

A: No. All substitute parts use identical DO-214AC (SMA) package geometry. Surface-mount footprints are interchangeable without PCB redesign.
