CD214A-T100CALF Equivalent & Substitute Parts

Part Overview

The CD214A-T100CALF 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 100V reverse standoff voltage with 162V maximum clamping voltage and 2.5A peak pulse current capability in a DO-214AC (SMA) 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 of the CD214A-T100CALF is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Reverse Standoff: 100V (Typ)
• Voltage - Breakdown: 111V (Min)
• Voltage - Clamping: 162V (Max @ Ipp)
• Current - Peak Pulse: 2.5A (10/1000µs)
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Type: Zener, Bidirectional (1 channel)
• RoHS Compliance: ROHS3 Compliant

All identified substitute parts match these core parameters, ensuring functional compatibility in the original application circuit. Packaging format and supplier device package remain consistent across all alternatives.

Parameter Comparison

Engineering Selection Recommendations

SMAJ100CA (MDD) is the primary direct equivalent for the CD214A-T100CALF. This part maintains identical electrical specifications and package format while offering active product status with substantial inventory availability (35,300 units). The operating temperature range of -50°C to 150°C covers the original specification minimum of -55°C; applications requiring the full -55°C lower limit should evaluate thermal performance in the specific circuit environment.

SMAJ100CA-TP (Micro Commercial Co) serves as an alternative with extended operating temperature range (-55°C to 175°C), providing additional thermal margin for demanding applications. This variant is supplied in Tape & Reel packaging format and maintains full electrical equivalence. The extended upper temperature limit of 175°C offers design flexibility for high-temperature environments.

Both substitute parts carry ROHS3 compliance and EAR99 export classification, matching the regulatory profile of the original component. Selection between alternatives should be based on packaging requirements (bulk versus tape & reel), inventory availability, and thermal operating envelope of the target application.

Frequently Asked Questions (FAQ)

Q: Can SMAJ100CA directly replace CD214A-T100CALF in existing PCB designs?

A: Yes. Both parts share identical electrical parameters (100V standoff, 162V clamping, 2.5A peak pulse) and the same DO-214AC (SMA) package footprint. No circuit modifications or PCB layout changes are required.

Q: What is the difference between SMAJ100CA and SMAJ100CA-TP?

A: The primary difference is packaging format and operating temperature range. SMAJ100CA-TP is supplied in Tape & Reel format and supports operation to 175°C (TA), compared to 150°C (TJ) for the standard SMAJ100CA. Both maintain identical electrical specifications.

Q: Why is the CD214A-T100CALF marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Bourns Inc. The substitute parts listed provide equivalent functionality and are actively produced, ensuring long-term design support and supply chain continuity.

Q: Are there temperature range considerations when substituting?

A: The SMAJ100CA operates to -50°C minimum (versus -55°C for the original). For applications requiring full -55°C operation, SMAJ100CA-TP with its -55°C to 175°C range is recommended. Verify thermal performance in your specific circuit design.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed alternatives are ROHS3 compliant and carry EAR99 export classification, matching the regulatory requirements of the original CD214A-T100CALF.

Q: What inventory status should I consider for production planning?

A: SMAJ100CA (MDD) offers the highest inventory availability at 35,300 units. SMAJ100CA-TP (Micro Commercial Co) has 901 units available. Both provide sufficient stock for immediate procurement.
