CD214A-T9.0ALF Equivalent & Substitute Parts

Part Overview

The CD214A-T9.0ALF 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 9V reverse standoff voltage with a 15.4V maximum clamping voltage and 26A peak pulse current capability in a DO-214AC (SMA) package. The part is currently listed 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-T9.0ALF is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 9V
• Voltage - Clamping (Max) @ Ipp: 15.4V
• Current - Peak Pulse (10/1000µs): 26A
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional

Substitution Categories:

Direct Equivalents maintain identical electrical specifications across all critical parameters. These parts are pin-compatible and functionally interchangeable without circuit modification.

Similar Alternatives share the same package and mounting type but may vary in one or more electrical parameters (voltage rating, peak current, or clamping voltage). These require circuit-level verification to confirm compatibility with the application's protection requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Preferred): SMAJ9.0A (MDD), SMAJ9.0A-TP (Micro Commercial Co), TV04A9V0J-G (Comchip Technology), and TV04A9V0J-HF (Comchip Technology) are direct electrical equivalents to the CD214A-T9.0ALF. All maintain the 9V reverse standoff voltage, 15.4V clamping voltage, and 26A peak pulse current specification. All substitute parts are active products with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). These parts are suitable for direct substitution in existing designs without circuit modification.

Alternative Selection (Conditional): SMAJ8.0A-M3/5A (Vishay) presents a lower voltage rating (8V standoff, 13.6V clamping) with higher peak pulse current (29.4A). This part is suitable only for applications where the lower voltage threshold is acceptable and the increased current capability provides additional margin. This part requires circuit-level analysis to confirm protection adequacy.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original part. Temperature operating ranges vary slightly; SMAJ9.0A-TP extends to 175°C (TA), while others remain at 150°C (TJ). Selection should account for the specific thermal environment of the application.

Frequently Asked Questions (FAQ)

Q: Can SMAJ9.0A directly replace CD214A-T9.0ALF? A: Yes. SMAJ9.0A maintains identical electrical specifications (9V standoff, 15.4V clamping, 26A peak pulse) and package configuration (DO-214AC, SMA). The part is pin-compatible and requires no circuit modification.

Q: What is the difference between SMAJ9.0A and SMAJ9.0A-TP? A: Both parts are electrically identical with matching voltage and current ratings. The primary difference is the extended operating temperature range of SMAJ9.0A-TP (-55°C ~ 175°C TA) compared to SMAJ9.0A (-50°C ~ 150°C TJ). Selection depends on the application's thermal requirements.

Q: Why is SMAJ8.0A-M3/5A listed as a similar alternative rather than a direct equivalent? A: SMAJ8.0A-M3/5A has a lower reverse standoff voltage (8V vs. 9V) and lower clamping voltage (13.6V vs. 15.4V), though it offers higher peak pulse current (29.4A vs. 26A). This part is suitable only when the lower voltage threshold meets application requirements and has been verified through circuit analysis.

Q: Are all substitute parts available in the same packaging? A: Yes. All listed substitute parts use the DO-214AC (SMA) surface-mount package, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: What compliance certifications apply to substitute parts? A: All substitute parts maintain ROHS3 compliance and carry EAR99 export classification. Moisture sensitivity level is MSL 1 (unlimited) for all parts, matching the original CD214A-T9.0ALF specification.

Q: Can I use TV04A9V0J-G or TV04A9V0J-HF interchangeably? A: Yes. Both Comchip parts are electrically identical with 9V standoff, 15.4V clamping, and 25.97A peak pulse current. The difference between -G and -HF variants relates to packaging or supplier designation but does not affect electrical performance or pin compatibility.
