CD214A-T75CALF Equivalent & Substitute Parts

Part Overview

The CD214A-T75CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection applications. This component features a 75V reverse standoff voltage with a 121V maximum clamping voltage and 3.3A peak pulse current capability in a surface-mount DO-214AC (SMA) package. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD214A-T75CALF is determined by strict electrical and mechanical parameter matching within the TVS diode category. The following criteria establish functional equivalence:

Critical Matching Parameters:

• Voltage - Reverse Standoff: 75V (±tolerance)
• Voltage - Clamping (Max) @ Ipp: 121V (±tolerance)
• Current - Peak Pulse (10/1000µs): ≥3.3A
• Power - Peak Pulse: ≥400W
• Package / Case: DO-214AC (SMA)
• Operating Temperature Range: -55°C ~ 150°C minimum
• Type: Zener, Bidirectional, 1 Channel

The SMAJ75CA from Meritek meets all critical electrical parameters with a peak pulse current of 3.31A and identical voltage specifications. Both components share the same DO-214AC (SMA) surface-mount package and temperature operating range, confirming mechanical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SMAJ75CA from Meritek is a direct functional equivalent to the obsolete CD214A-T75CALF. Both components are ROHS3 compliant and share identical electrical specifications across all critical parameters. The SMAJ75CA maintains active product status with 20,100 units in stock, providing supply continuity for applications currently using the CD214A-T75CALF.

Selection between these components should be based on availability and supply chain requirements. The SMAJ75CA is supplied in Tape & Reel (TR) packaging, whereas the original part's packaging format is not specified. Both components are suitable for general-purpose transient voltage suppression applications requiring 75V standoff protection with 121V clamping characteristics.

Frequently Asked Questions (FAQ)

Q: Can the SMAJ75CA directly replace the CD214A-T75CALF in existing designs?

A: Yes. Both components share identical electrical specifications (75V standoff, 121V clamping, 3.3A peak pulse current) and the same DO-214AC (SMA) surface-mount package. No circuit modifications are required.

Q: What is the difference between the 3.3A and 3.31A peak pulse current ratings?

A: The 0.01A difference falls within normal manufacturing tolerance for TVS diodes and does not affect functional equivalence. Both ratings satisfy the 3.3A minimum requirement for this application category.

Q: Are there compliance differences between the two parts?

A: Both components are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. The CD214A-T75CALF is REACH Affected, while the SMAJ75CA is REACH Unaffected. Verify REACH compliance requirements for your specific application and region.

Q: Does packaging format affect substitution?

A: The SMAJ75CA is supplied in Tape & Reel (TR) format. If your assembly process requires a different packaging format, confirm compatibility with your procurement and manufacturing specifications before implementation.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both components have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
