CD214A-T7.0CALF Equivalent & Substitute Parts

Part Overview

The CD214A-T7.0CALF is a Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., classified as a unidirectional Zener-type device in the DO-214AC (SMA) surface mount package. This component is designed for general-purpose transient voltage suppression applications with a 7V reverse standoff voltage and 12V maximum clamping voltage at peak pulse current. The part is currently listed as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD214A-T7.0CALF are identified based on strict electrical and mechanical parameter matching within the TVS diode category. The substitution criteria are:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 7V
• Voltage - Breakdown (Min): 7.78V
• Voltage - Clamping (Max) @ Ipp: 12V
• Current - Peak Pulse (10/1000µs): 33.3A
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Type: Zener (unidirectional)
• Bidirectional Channels: 1
• Mounting Type: Surface Mount

All identified substitute parts match these parameters exactly. Variations in operating temperature range, manufacturer, and product status (active vs. obsolete) do not affect functional equivalence for the specified electrical performance.

Parameter Comparison

Engineering Selection Recommendations

SMAJ7.0CA (MDD) and SMAJ7.0CA-TP (Micro Commercial Co) are direct functional equivalents to the CD214A-T7.0CALF. Both substitute parts are currently in active production status, addressing the obsolescence of the original Bourns component.

All three parts are ROHS3 compliant and carry identical electrical specifications for voltage suppression performance. The substitute parts from MDD and Micro Commercial Co offer improved availability compared to the obsolete Bourns part, with 10,100 and 7,260 units respectively in current inventory.

The SMAJ7.0CA-TP variant from Micro Commercial Co provides an extended operating temperature range (-55°C ~ 175°C TA) compared to the original part (-55°C ~ 150°C TJ), offering additional thermal margin for applications requiring higher temperature operation.

Frequently Asked Questions (FAQ)

Q: Can SMAJ7.0CA and SMAJ7.0CA-TP be used interchangeably with CD214A-T7.0CALF?

A: Yes. Both parts match all critical electrical parameters: 7V reverse standoff voltage, 7.78V minimum breakdown voltage, 12V maximum clamping voltage, 33.3A peak pulse current, and 400W peak pulse power. All three are packaged in DO-214AC (SMA) surface mount configuration with identical pinout and footprint compatibility.

Q: What is the difference between SMAJ7.0CA and SMAJ7.0CA-TP?

A: Both parts are electrically identical with matching voltage and current ratings. The primary difference is the operating temperature range: SMAJ7.0CA operates from -50°C to 150°C (TJ), while SMAJ7.0CA-TP operates from -55°C to 175°C (TA). SMAJ7.0CA-TP is suitable for applications requiring extended low-temperature performance or higher ambient temperature operation.

Q: Are there packaging differences between these parts?

A: The CD214A-T7.0CALF is supplied in standard packaging. Both SMAJ7.0CA and SMAJ7.0CA-TP are supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. The physical component dimensions and PCB footprint remain identical across all three parts.

Q: Why is the original CD214A-T7.0CALF listed as obsolete?

A: Obsolescence status indicates the part is no longer manufactured by Bourns Inc. The SMAJ7.0CA and SMAJ7.0CA-TP alternatives provide equivalent performance from active manufacturers, ensuring long-term component availability for new designs and production support.

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

A: Yes. All three parts are ROHS3 compliant and carry EAR99 ECCN classification. The SMAJ7.0CA and SMAJ7.0CA-TP are REACH unaffected, while the original CD214A-T7.0CALF is REACH affected. All parts carry Moisture Sensitivity Level 1 (Unlimited).
