Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMAJ110CA-M3/61 are qualified based on the following critical parameters that determine functional equivalence:

• Voltage - Reverse Standoff (Typ): 110V
• Voltage - Breakdown (Min): 122V
• Voltage - Clamping (Max) @ Ipp: 177V
• Package / Case: DO-214AC (SMA)
• Mounting Type: Surface Mount
• Type: Zener, Bidirectional (1 channel)
• Operating Temperature Range: -55°C ~ 150°C

Substitute parts must maintain identical voltage specifications and package configuration to ensure direct circuit compatibility. Peak pulse current and power ratings may vary within acceptable ranges for the application category, provided the part remains rated for general-purpose transient voltage suppression.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain identical voltage specifications (110V standoff, 122V breakdown minimum, 177V clamping maximum) and identical package configuration (DO-214AC/SMA surface mount). All parts are Active status with ROHS3 compliance and REACH Unaffected designation.

SMAJ110CA-E3/61 (Vishay) is a direct equivalent to SMAJ110CA-M3/61, differing only in tape reel configuration (E3/61 versus M3/61). Both are manufactured by Vishay with identical electrical specifications and are interchangeable at the circuit level.

SMAJ110CA (Meritek) provides equivalent voltage protection with higher peak pulse current (2.26A versus 1.7A) and higher peak pulse power (400W versus 300W). This part exceeds the minimum performance requirements and is suitable for applications requiring enhanced transient suppression capability within the same voltage class.

Frequently Asked Questions (FAQ)

Q: Can SMAJ110CA-E3/61 replace SMAJ110CA-M3/61 directly?

A: Yes. Both parts are manufactured by Vishay with identical electrical specifications. The difference is in tape reel configuration (E3/61 versus M3/61), which does not affect circuit performance or PCB assembly compatibility.

Q: Is the Meritek SMAJ110CA a suitable substitute?

A: Yes. The Meritek part maintains all critical voltage specifications (110V standoff, 122V breakdown, 177V clamping) and identical package configuration. The higher peak pulse current (2.26A) and power rating (400W) provide enhanced performance margins within the same voltage protection class.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the DO-214AC (SMA) package and surface mount configuration, ensuring identical PCB footprint compatibility.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH Unaffected, and rated for MSL 1 (Unlimited moisture sensitivity level). All parts maintain Active product status.

Q: Do the substitute parts operate within the same temperature range?

A: Yes. All parts are rated for -55°C to 150°C operating temperature, ensuring thermal compatibility across the specified range.
