Substitutes maintain identical voltage specifications and package form factor, with peak pulse current within the specified range. All substitute parts are Active status and meet ROHS3 compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core electrical and mechanical requirements for direct substitution. Selection should be based on the following factors:

SMAJ110CA (Meritek): Functionally equivalent with 2.26A peak pulse current, meeting the minimum specification. Operating temperature range extends to 150°C. Suitable for applications where the lower temperature rating is acceptable and cost optimization is a priority.

SMAJ110CA-13-F (Diodes Incorporated): Matches the original part specification with 2.3A peak pulse current and identical electrical characteristics. Operating temperature range extends to 150°C. Recommended for applications requiring exact performance parity with the original SMAJ110CA-TP.

SMAJ110CA-TP (Micro Commercial Co): Original specification with extended operating temperature range to 175°C. Recommended for high-temperature applications or when maximum thermal margin is required.

All parts are Active status, ROHS3 compliant, and carry Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can SMAJ110CA (Meritek) be used as a direct replacement for SMAJ110CA-TP?

A: Yes. Both parts share identical voltage specifications (110V standoff, 122V breakdown, 177V clamping) and package form factor (DO-214AC SMA). The peak pulse current of 2.26A meets the application requirement. The operating temperature range difference (150°C vs 175°C) should be evaluated based on circuit thermal conditions.

Q: What is the difference between SMAJ110CA-13-F and SMAJ110CA-TP?

A: Both parts are electrically identical with matching voltage and current specifications. The primary difference is the operating temperature range: SMAJ110CA-13-F operates to 150°C while SMAJ110CA-TP extends to 175°C. For applications operating below 150°C, both are functionally equivalent.

Q: Are all substitute parts in the same package?

A: Yes. All three parts use the DO-214AC (SMA) surface-mount package, ensuring mechanical and footprint compatibility on PCBs designed for the SMAJ110CA-TP.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. All parts listed are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), meeting modern manufacturing and environmental standards.

Q: Which substitute should I select for a high-temperature application?

A: The SMAJ110CA-TP is rated to 175°C and is the appropriate choice for applications requiring maximum thermal operating range. Substitute parts are rated to 150°C and should only be used if circuit thermal conditions remain below this limit.
