Substitute Part Grouping Explanation
Substitution for the CD214C-T5.0CALF is determined by strict electrical and mechanical parameter matching:
Primary Substitution Criteria:
- Reverse standoff voltage: 5V
- Breakdown voltage minimum: 6.4V
- Clamping voltage maximum @ Ipp: 9.2V
- Peak pulse current: 163A minimum
- Peak pulse power: 1500W
- Package: DO-214AB (SMC)

Engineering Selection Recommendations
Recommended Direct Substitutes (Highest Compatibility):
SMCJ5.0CA (Taiwan Semiconductor Corporation) and SMCJ5.0CA-M3/57T (Vishay) are the primary alternatives. Both maintain exact electrical specifications matching the CD214C-T5.0CALF, with active product status and ROHS3 compliance. SMCJ5.0CA offers higher inventory availability (8848 pcs) and identical operating temperature range. SMCJ5.0CA-M3/57T provides the TransZorb® series designation with equivalent performance.
Extended Temperature Range Options:
SMCJ5.0CA-HR, SMCJ5.0CA-HRA, and SMCJ5.0CA-HRAT7 (Littelfuse Inc.) extend the lower operating temperature limit to -65°C while maintaining all other electrical parameters. These are suitable for applications requiring enhanced cold-temperature performance.
Enhanced Temperature Capability:
SMCJ5.0CA-TP (Micro Commercial Co) extends the upper operating temperature to 175°C, providing additional thermal margin for high-temperature environments while maintaining all core electrical specifications.
Note on SMCJ5.0CA-TR (STMicroelectronics):
This part exhibits significantly different electrical characteristics with 13.4V clamping voltage and 746A peak pulse current. While it shares the same package and 5V standoff voltage, the elevated clamping voltage makes it unsuitable as a direct substitute for applications requiring 9.2V clamping performance.
All recommended substitutes carry ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental certifications.
Frequently Asked Questions (FAQ)
Q: Can SMCJ5.0CA directly replace CD214C-T5.0CALF without circuit modification?
A: Yes. SMCJ5.0CA maintains identical electrical specifications: 5V standoff voltage, 6.4V minimum breakdown voltage, 9.2V maximum clamping voltage, and 163A peak pulse current capability. The DO-214AB (SMC) package is mechanically identical. No circuit changes are required.
Q: What is the difference between SMCJ5.0CA and SMCJ5.0CA-HR?
A: Both parts meet the same electrical specifications. SMCJ5.0CA-HR extends the lower operating temperature limit from -55°C to -65°C. Select SMCJ5.0CA-HR for applications requiring enhanced cold-temperature performance.
Q: Why is SMCJ5.0CA-TR listed as a similar alternative rather than a direct substitute?
A: SMCJ5.0CA-TR has a 13.4V maximum clamping voltage and 746A peak pulse current, significantly different from the CD214C-T5.0CALF specification of 9.2V clamping and 163A peak current. While it shares the same 5V standoff voltage and package, the elevated clamping voltage alters circuit protection characteristics and makes it unsuitable as a direct replacement.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original CD214C-T5.0CALF environmental standard.
Q: What packaging options are available for substitute parts?
A: Substitute parts are available in Cut Tape (CT) & Digi-Reel® or Tape & Reel (TR) packaging. All maintain the DO-214AB (SMC) component package for surface mount assembly compatibility.
Q: Can SMCJ5V0CA be used as a substitute?
A: SMCJ5V0CA meets all electrical specifications and package requirements. However, its operating temperature range is not specified in available documentation. For applications with defined temperature requirements, SMCJ5.0CA or SMCJ5.0CA-M3/57T are preferred due to fully documented thermal specifications.
