Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD214A-T8.0CALF is determined by the following critical parameters:

Primary Matching Criteria:

• Voltage - Reverse Standoff (Typ): 8V
• Voltage - Clamping (Max) @ Ipp: 13.6V
• Current - Peak Pulse (10/1000µs): 29.4A
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Power - Peak Pulse: 400W

Substitute Categories:

Direct Equivalents meet all primary matching criteria with identical electrical specifications and package configuration. These parts provide pin-for-pin and functional replacement capability.

Similar Alternatives share the same package and mounting type but differ in one or more electrical parameters (voltage ratings or peak pulse current). These parts are suitable only when the application circuit can tolerate the specified parameter variations.

Engineering Selection Recommendations

SMAJ8.0CA (MDD) - Direct Equivalent

The SMAJ8.0CA provides complete functional equivalence to the CD214A-T8.0CALF with identical electrical specifications across all critical parameters. This part is currently in active production status with substantial inventory availability (50,100 pcs). The component maintains ROHS3 compliance and operates within the same temperature range as the original part. The SMAJ8.0CA is the primary recommendation for direct replacement in all applications previously using the CD214A-T8.0CALF.

SMAJ8.0CA-TP (Micro Commercial Co) - Direct Equivalent

The SMAJ8.0CA-TP matches all electrical specifications of the main part and is available in active production status (1,047 pcs in stock). This part offers an extended operating temperature range to -55°C ~ 175°C (TA), providing additional thermal margin in high-temperature environments. ROHS3 compliance and REACH unaffected status are confirmed. The SMAJ8.0CA-TP is suitable for applications requiring enhanced thermal performance.

SMAJ7.5CA-M3/5A (Vishay) - Similar Alternative

The SMAJ7.5CA-M3/5A operates at a lower reverse standoff voltage (7.5V) and clamping voltage (12.9V) compared to the main part, with a slightly higher peak pulse current (31A). This part is appropriate only for applications where the lower voltage ratings are compatible with circuit requirements. Active production status and ROHS3 compliance are confirmed. The extended operating temperature range (-55°C ~ 150°C) matches the original specification.

SMAJ9.0CA-TP (Micro Commercial Co) - Similar Alternative

The SMAJ9.0CA-TP operates at a higher reverse standoff voltage (9V) and clamping voltage (15.4V) with a lower peak pulse current (26A). This part is suitable only for applications tolerating higher voltage thresholds and reduced current capacity. Active production status and extended operating temperature range (-55°C ~ 175°C) are confirmed. RoHS status is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can SMAJ8.0CA be used as a direct replacement for CD214A-T8.0CALF?

A: Yes. The SMAJ8.0CA provides identical electrical specifications including 8V reverse standoff voltage, 13.6V clamping voltage, and 29.4A peak pulse current. Both components use the DO-214AC (SMA) package with surface-mount configuration. The SMAJ8.0CA is in active production and is the recommended direct replacement.

Q: What is the difference between SMAJ8.0CA and SMAJ8.0CA-TP?

A: Both parts have identical electrical specifications. The primary difference is operating temperature range: SMAJ8.0CA operates from -50°C to 150°C (TJ), while SMAJ8.0CA-TP operates from -55°C to 175°C (TA). Select SMAJ8.0CA-TP for applications requiring extended thermal performance.

Q: Can SMAJ7.5CA-M3/5A replace the CD214A-T8.0CALF?

A: SMAJ7.5CA-M3/5A is a similar alternative only, not a direct equivalent. It operates at lower voltage ratings (7.5V standoff, 12.9V clamping) with higher peak pulse current (31A). Use this part only if your circuit design can accommodate the lower voltage thresholds.

Q: Can SMAJ9.0CA-TP replace the CD214A-T8.0CALF?

A: SMAJ9.0CA-TP is a similar alternative only. It operates at higher voltage ratings (9V standoff, 15.4V clamping) with lower peak pulse current (26A). Use this part only if your circuit design tolerates higher voltage thresholds and reduced current capacity.

Q: Are all substitute parts RoHS compliant?

A: SMAJ8.0CA, SMAJ8.0CA-TP, and SMAJ7.5CA-M3/5A are confirmed ROHS3 compliant. SMAJ9.0CA-TP RoHS status is not specified in available documentation. Verify RoHS compliance requirements with your supply chain before selection.

Q: Do all substitute parts have the same package configuration?

A: Yes. All substitute parts use the DO-214AC (SMA) surface-mount package, providing identical PCB footprint compatibility with the CD214A-T8.0CALF.

Q: What is the inventory status of available substitutes?

A: SMAJ8.0CA has the highest inventory availability (50,100 pcs). SMAJ9.0CA-TP has 1,105 pcs available. SMAJ8.0CA-TP has 1,047 pcs available. SMAJ7.5CA-M3/5A has 693 pcs available. Verify current stock levels with your supplier before finalizing procurement decisions.
