Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214L-T8.5CALF is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 8.5V ± tolerance
• Voltage - Clamping (Max) @ Ipp: 14.4V ± tolerance
• Current - Peak Pulse (10/1000µs): 208.4A ± tolerance
• Power - Peak Pulse: 3000W (3kW)
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Bidirectional Channels: 1

Substitute parts are grouped into two categories:

Direct Equivalents (Full Parameter Match): Parts meeting all critical electrical specifications and power rating of 3000W with identical clamping voltage and peak pulse current.

Similar Alternatives (Partial Parameter Match): Parts with matching voltage standoff and clamping characteristics but reduced peak pulse current (104A–109A) and power rating (1500W), suitable for applications with lower transient energy requirements. These parts maintain voltage compatibility but differ in surge handling capacity.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Electrical Equivalence):

SMLJ8.5CA (Bourns Inc., Active) and SMDJ8.5CA (Alpha & Omega Semiconductor Inc., Active) are direct functional equivalents with identical electrical specifications and 3000W power rating. Both are ROHS3 compliant and actively manufactured. SMLJ8.5CA is available in Tape & Reel packaging with 925 pcs in stock. SMDJ8.5CA is available in Tape & Reel packaging with 12,200 pcs in stock.

SMDJ8.5CA-HR and SMDJ8.5CA-HRA (Littelfuse Inc., Active) are high-reliability variants with identical electrical performance and 3000W power rating. Both feature extended operating temperature range to -65°C and are ROHS3 compliant. SMDJ8.5CA-HR has 869 pcs in stock; SMDJ8.5CA-HRA has 1,058 pcs in stock.

Secondary Substitutes (Reduced Power Handling):

SMCJ8.5CA (Taiwan Semiconductor Corporation, Active), SMCJ8.5CA-TP (Micro Commercial Co, Active), and SMCJ8V5CA (Fairchild Semiconductor, Active) maintain identical voltage specifications (8.5V standoff, 14.4V clamping) but operate at 1500W peak pulse power with reduced peak pulse current (104A–109A). These are suitable for applications with lower transient energy requirements. All are ROHS3 compliant and actively produced.

Voltage-Compatible Alternatives (Modified Clamping Voltage):

1.5SMC10CA (Taiwan Semiconductor Corporation, Active) and 1.5SMC10CA-E3/57T (Vishay General Semiconductor, Active) provide 8.55V standoff voltage with 14.5V clamping and 1500W power rating. These are suitable for applications tolerating slightly higher clamping voltage. 1.5SMC10CA-E3/57T extends operating temperature to -65°C.

SM15T10CA (STMicroelectronics, Active) offers 8.55V standoff voltage but features elevated clamping voltage of 18.6V and significantly higher peak pulse current of 538A (8/20µs pulse). This part is suitable only for applications where higher clamping voltage is acceptable.

Frequently Asked Questions (FAQ)

Q: Can SMCJ8.5CA be used as a direct replacement for CD214L-T8.5CALF?

A: SMCJ8.5CA maintains identical voltage specifications (8.5V standoff, 14.4V clamping) and package (DO-214AB, SMC) but operates at 1500W peak pulse power versus the original 3000W. Substitution is valid only if the application transient energy does not exceed 1500W. For applications requiring 3000W handling capacity, use SMLJ8.5CA or SMDJ8.5CA instead.

Q: What is the difference between SMDJ8.5CA-HR and SMDJ8.5CA-HRA?

A: Both are high-reliability variants from Littelfuse Inc. with identical electrical specifications and 3000W power rating. The primary distinction is series designation (SMDJ-HR versus SMDJ-HRA). Both support -65°C to 150°C operating temperature range and are ROHS3 compliant. Selection between them depends on specific procurement or qualification requirements.

Q: Is SM15T10CA suitable as a substitute?

A: SM15T10CA matches the 8.55V standoff voltage but features 18.6V clamping voltage versus the original 14.4V. This elevated clamping voltage may cause circuit malfunction in applications with strict voltage limits. Use only if the circuit design accommodates higher clamping voltage. For standard voltage compatibility, select parts with 14.4V or 14.5V clamping.

Q: What packaging options are available for substitutes?

A: All substitute parts use DO-214AB (SMC) surface mount package, matching the original. Packaging formats vary: SMLJ8.5CA is supplied in Tape & Reel; SMDJ8.5CA, SMDJ8.5CA-HR, and SMDJ8.5CA-HRA are supplied in Tape & Reel; SMCJ8.5CA is supplied without specified packaging; SMCJ8.5CA-TP is supplied in Tape & Reel; SMCJ8V5CA is supplied in Bulk; 1.5SMC10CA and 1.5SMC10CA-E3/57T are supplied in Tape & Reel; SM15T10CA is supplied in Cut Tape & Digi-Reel.

Q: Are all substitutes RoHS3 compliant?

A: All listed substitute parts are ROHS3 compliant. The original CD214L-T8.5CALF is also ROHS3 compliant. Compliance status is consistent across all options.

Q: Which substitute offers the highest inventory availability?

A: SMCJ8V5CA (Fairchild Semiconductor) has the highest inventory with 30,100 pcs in stock. SMCJ8.5CA (Taiwan Semiconductor Corporation) has 15,200 pcs. SM15T10CA (STMicroelectronics) has 17,460 pcs. For 3000W power-rated equivalents, SMDJ8.5CA offers 12,200 pcs in stock.
