CD214A-T110ALF Equivalent & Substitute Parts

Part Overview

The CD214A-T110ALF 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 equivalent substitutes necessary for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD214A-T110ALF is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 110V
• Voltage - Clamping (Max) @ Ipp: 177V
• Current - Peak Pulse (10/1000µs): 2.3A (±tolerance acceptable)
• Package / Case: DO-214AC (SMA)
• Type: Zener, Unidirectional
• Mounting Type: Surface Mount

Substitute parts are grouped into two categories:

Direct Equivalents: Parts with identical electrical specifications (110V standoff, 177V clamping, 2.3A peak pulse) and matching package configuration.

Similar Alternatives: Parts with comparable voltage ratings and clamping characteristics within the same package family, suitable for applications where minor parameter variations are acceptable within circuit design margins.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents)

SMAJ110A-TP (Micro Commercial Co) and SMAJ110A (Meritek) are the preferred direct substitutes. Both maintain identical voltage specifications (110V standoff, 177V clamping) and peak pulse current (2.3A or 2.26A) within acceptable tolerance. SMAJ110A-TP offers extended operating temperature range (-55°C ~ 175°C) compared to the original specification, providing additional thermal margin. Both parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating.

TV04A111J-G (Comchip Technology) provides equivalent electrical performance with 2.26A peak pulse current and identical voltage ratings. This part is actively manufactured and maintains full compliance certifications.

Secondary Alternative

SMAJ120A-13-F (Diodes Incorporated) operates at a higher voltage rating (120V standoff, 193V clamping) with reduced peak pulse current (2A). This part is suitable only for applications where the elevated voltage rating does not conflict with circuit design requirements and where the lower current capacity is acceptable. This part carries automotive-grade qualification.

All substitute parts are available in active production status with current inventory, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can SMAJ110A replace CD214A-T110ALF directly?

A: Yes. SMAJ110A maintains identical voltage specifications (110V standoff, 177V clamping) and equivalent peak pulse current (2.26A vs 2.3A). Both use DO-214AC (SMA) packaging and operate across the same temperature range. The part is actively manufactured by Meritek.

Q: What is the difference between SMAJ110A and SMAJ110A-TP?

A: Both parts share identical electrical specifications. SMAJ110A-TP, manufactured by Micro Commercial Co, extends the operating temperature range to -55°C ~ 175°C (versus -55°C ~ 150°C for standard SMAJ110A), providing additional thermal headroom in high-temperature applications.

Q: Is SMAJ120A-13-F a suitable replacement?

A: SMAJ120A-13-F operates at higher voltage ratings (120V standoff, 193V clamping) with reduced peak pulse current (2A). Substitution is valid only if circuit design margins accommodate the elevated clamping voltage and the application does not require the full 2.3A peak pulse current capacity.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, matching the original CD214A-T110ALF specification.

Q: What is the package compatibility?

A: All substitute parts use DO-214AC (SMA) surface-mount packaging, ensuring PCB footprint and reflow process compatibility with the original design.

Q: Do substitute parts have the same moisture sensitivity rating?

A: Yes. All substitute parts carry MSL 1 (Unlimited) rating, identical to the original component, requiring no changes to storage or handling procedures.
