Substitute Part Grouping Explanation

Substitution of the CD214A-T90CALF is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitute relationships:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 90V
• Voltage - Breakdown (Min): 100V
• Voltage - Clamping (Max) @ Ipp: 146V
• Current - Peak Pulse (10/1000µs): 2.7A
• Power - Peak Pulse: 400W
• Bidirectional Channels: 1
• Type: Zener

Mechanical Parameters (Must Match):

• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• ECCN: EAR99
• HTSUS: 8541.10.0080

The SMAJ90CA from MDD satisfies all electrical, mechanical, and compliance requirements and qualifies as a direct substitute for the CD214A-T90CALF.

Parameter Comparison

*Operating temperature range: SMAJ90CA operates from -50°C to 150°C, while CD214A-T90CALF operates from -55°C to 150°C. The SMAJ90CA does not extend to the lower temperature limit of the original part.

Engineering Selection Recommendations

SMAJ90CA (MDD) - Direct Substitute

The SMAJ90CA is a direct electrical and mechanical equivalent to the CD214A-T90CALF. Both components share identical voltage ratings, current specifications, power dissipation, package configuration, and compliance certifications.

The SMAJ90CA is classified as active product status, ensuring ongoing availability and supply chain support. The component maintains ROHS3 compliance and carries the same ECCN and HTSUS classifications as the original part.

The primary design consideration is the operating temperature range. The SMAJ90CA specifies a minimum operating temperature of -50°C, whereas the CD214A-T90CALF extends to -55°C. Applications requiring operation below -50°C must retain the original CD214A-T90CALF or identify alternative components with extended low-temperature specifications.

For applications operating within the -50°C to 150°C range, the SMAJ90CA provides full functional equivalence with improved supply availability.

Frequently Asked Questions (FAQ)

Q: Can the SMAJ90CA be used as a direct replacement for the CD214A-T90CALF in all applications?

A: The SMAJ90CA is electrically and mechanically equivalent for applications operating within the -50°C to 150°C temperature range. Applications requiring operation below -50°C must use the original CD214A-T90CALF or identify components with extended low-temperature ratings.

Q: Are the package dimensions identical between CD214A-T90CALF and SMAJ90CA?

A: Both components use the DO-214AC (SMA) surface-mount package. Mechanical compatibility is confirmed for PCB layout and assembly processes.

Q: What is the difference in product status between these parts?

A: The CD214A-T90CALF is classified as obsolete, indicating discontinued manufacturing. The SMAJ90CA is classified as active, confirming current production and ongoing availability.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both the CD214A-T90CALF and SMAJ90CA are ROHS3 compliant, carry EAR99 ECCN classification, and share the same HTSUS code (8541.10.0080).

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution is determined by matching voltage ratings (90V reverse standoff, 100V breakdown minimum, 146V clamping maximum), peak pulse current (2.7A), peak pulse power (400W), and zener type with single bidirectional channel configuration.

Q: Is the SMAJ90CA available in sufficient quantity for production requirements?

A: The SMAJ90CA has 37,200 pieces in stock as new original inventory, providing substantial availability for production and design transitions.
