CD214L-T160ALF Equivalent & Substitute Parts

Part Overview

The CD214L-T160ALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., classified as a unidirectional Zener-type device in the DO-214AB (SMC) package. This component is designed for general-purpose transient voltage suppression applications with a reverse standoff voltage of 160V and a clamping voltage of 259V at peak pulse current.

The CD214L-T160ALF is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements. Substitute parts must maintain electrical compatibility across critical parameters including reverse standoff voltage, breakdown voltage, clamping voltage, and peak pulse current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD214L-T160ALF are grouped based on strict electrical and mechanical compatibility criteria. All substitute candidates must satisfy the following mandatory parameters:

• Reverse standoff voltage: 160V (typical)
• Breakdown voltage (minimum): 178V
• Clamping voltage (maximum at Ipp): 259V
• Package / Case: DO-214AB, SMC
• Mounting type: Surface Mount
• Unidirectional channels: 1
• Type: Zener

Substitute parts are classified into two categories:

Direct Substitutes (Identical Electrical Performance): Parts with matching peak pulse current (11.6A) and power dissipation (3000W). These parts are fully interchangeable with the CD214L-T160ALF.

Similar Substitutes (Enhanced Performance): Parts with higher peak pulse current (19.3A) and power dissipation (5000W), or lower peak pulse current (5.8A) and power dissipation (1500W). These parts maintain voltage compatibility but differ in current-handling capacity and thermal performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SMLJ160A (Bourns Inc.)

The SMLJ160A is the preferred direct substitute for the CD214L-T160ALF. Both parts are manufactured by Bourns Inc. and maintain identical electrical specifications: 160V reverse standoff voltage, 178V minimum breakdown voltage, 259V clamping voltage, 11.6A peak pulse current, and 3000W peak pulse power. The SMLJ160A is currently in active production status, ensuring long-term supply availability. Both parts are ROHS3 compliant and carry identical moisture sensitivity levels (MSL 1 - Unlimited). The primary distinction is packaging: SMLJ160A is supplied in Tape & Reel format, whereas the original part number does not specify packaging detail.

Secondary Recommendation: SMDJ160A (Alpha & Omega Semiconductor Inc.)

The SMDJ160A provides direct electrical equivalence to the CD214L-T160ALF with matching peak pulse current (11.6A) and power dissipation (3000W). This part is actively produced and available in high inventory quantities (4400 Pcs). SMDJ160A is ROHS3 compliant and REACH unaffected. Selection of this part is appropriate when Bourns supply is constrained or when Alpha & Omega Semiconductor qualification is required by design standards.

Alternative for Enhanced Transient Protection: 5.0SMDJ160A-T7 (Littelfuse Inc.)

The 5.0SMDJ160A-T7 maintains voltage compatibility (160V standoff, 259V clamping) while providing enhanced current handling (19.3A peak pulse) and power dissipation (5000W). This part supports applications requiring higher transient energy absorption. Operating temperature range extends to -65°C minimum, providing improved low-temperature performance compared to the original specification (-55°C). This part is suitable for telecom applications and is actively produced by Littelfuse Inc.

Alternative for Cost-Optimized Applications: SMCJ160A or SMCJ160A-TP

Both SMCJ160A (Fairchild Semiconductor) and SMCJ160A-TP (Micro Commercial Co) maintain voltage specifications but operate at reduced peak pulse current (5.8A) and power dissipation (1500W). These parts are appropriate for applications where transient energy levels are lower than the original design specification. SMCJ160A-TP offers extended operating temperature range to 175°C, supporting high-temperature environments. High inventory availability (17400 Pcs for SMCJ160A) supports cost-effective procurement.

All recommended substitutes maintain the DO-214AB (SMC) package format and surface-mount configuration, ensuring mechanical compatibility with existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can SMLJ160A directly replace CD214L-T160ALF without circuit modification?

A: Yes. SMLJ160A maintains identical electrical specifications across all critical parameters: reverse standoff voltage (160V), breakdown voltage (178V), clamping voltage (259V), peak pulse current (11.6A), and power dissipation (3000W). Both parts use the DO-214AB (SMC) package. No circuit modifications are required.

Q: What is the difference between direct substitutes and similar substitutes?

A: Direct substitutes (SMLJ160A, SMDJ160A) match the original part's peak pulse current (11.6A) and power dissipation (3000W). Similar substitutes differ in current-handling capacity: 5.0SMDJ160A-T7 provides enhanced performance (19.3A, 5000W), while SMCJ160A and SMCJ160A-TP provide reduced performance (5.8A, 1500W). All maintain voltage compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: SMLJ160A, 5.0SMDJ160A-T7, SMCJ160A-TP, and SMDJ160A are confirmed ROHS3 compliant. SMCJ160A (Fairchild Semiconductor) does not specify ROHS status in the provided data. Verify ROHS compliance with the manufacturer if required by procurement standards.

Q: What packaging formats are available for substitute parts?

A: SMLJ160A, 5.0SMDJ160A-T7, SMCJ160A-TP, and SMDJ160A are supplied in Tape & Reel (TR) format. SMCJ160A (Fairchild Semiconductor) is supplied in Bulk format. Tape & Reel packaging is standard for automated assembly processes.

Q: Can I use SMCJ160A-TP in applications requiring operation above 150°C?

A: Yes. SMCJ160A-TP supports operating temperatures up to 175°C, compared to 150°C for most other substitutes. This part is suitable for high-temperature environments. However, verify that the reduced peak pulse current (5.8A) and power dissipation (1500W) meet application transient energy requirements.

Q: Which substitute offers the best transient protection capability?

A: 5.0SMDJ160A-T7 provides the highest transient energy absorption with 19.3A peak pulse current and 5000W power dissipation, compared to 11.6A and 3000W for the original part. This part is appropriate for applications experiencing high-energy transient events. Verify that circuit design supports the enhanced performance characteristics.

Q: Are there supply chain differences between substitute manufacturers?

A: Yes. SMLJ160A (Bourns Inc.) has 673 Pcs in stock. SMDJ160A (Alpha & Omega Semiconductor Inc.) has 4400 Pcs in stock. 5.0SMDJ160A-T7 (Littelfuse Inc.) has 1139 Pcs in stock. SMCJ160A (Fairchild Semiconductor) has 17400 Pcs in stock. Inventory levels may influence procurement decisions for high-volume production.

Q: Do substitute parts maintain the same moisture sensitivity level?

A: SMLJ160A, 5.0SMDJ160A-T7, SMCJ160A-TP, and SMDJ160A all specify MSL 1 (Unlimited), matching the original part. SMCJ160A (Fairchild Semiconductor) does not specify MSL in the provided data. Verify moisture sensitivity requirements with the manufacturer if component storage or handling protocols are critical.
