Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4SMA62A-M3/61 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Voltage - Reverse Standoff (Typ): 53V
• Voltage - Clamping (Max) @ Ipp: 85V
• Current - Peak Pulse (10/1000µs): 4.7A to 4.8A
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Unidirectional Channels: 1

Substitute Classification:

Direct Equivalents (Same Electrical Specifications): Parts that maintain identical voltage ratings, clamping characteristics, and peak pulse current within acceptable tolerance.

Manufacturer Variants (Same Base Series): Parts from the same P4SMA series with identical electrical performance but different manufacturer sources or packaging configurations.

Non-Equivalent Parts (Different Voltage Class): Parts listed in the substitute database that operate in different voltage ranges and are not suitable for direct replacement in this application.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Recommended for Replacement):

P4SMA62A-E3/61 and P4SMA62A are suitable direct substitutes for the P4SMA62A-M3/61. Both maintain identical voltage specifications (53V reverse standoff, 85V clamping), equivalent peak pulse current ratings (4.7A to 4.8A), and compatible DO-214AC SMA packaging. All three parts are Active status with RoHS compliance. The P4SMA62A-E3/61 offers higher inventory availability (3700 pcs) compared to the main part (915 pcs). The P4SMA62A from Eaton maintains the same electrical performance with a slightly higher peak pulse current (4.8A) and operates across a narrower temperature range (-55°C to 150°C versus -65°C to 150°C).

Non-Equivalent Parts (Not Recommended for Direct Replacement):

The P4SMA6.8A is not a suitable substitute. This part operates in a different voltage class (5.8V reverse standoff, 10.5V clamping) with significantly higher peak pulse current (40A). While it shares the same package type and series designation, the electrical characteristics are fundamentally different and incompatible with circuits designed for 53V protection levels.

Frequently Asked Questions (FAQ)

Q: Can P4SMA62A-E3/61 be used as a direct replacement for P4SMA62A-M3/61?

A: Yes. Both parts are identical in electrical specifications: 53V reverse standoff voltage, 85V clamping voltage, and 4.7A peak pulse current. Both use DO-214AC SMA packaging and are RoHS3 compliant. The primary difference is packaging configuration (E3/61 versus M3/61 tape reel specifications) and inventory availability.

Q: What is the difference between P4SMA62A and P4SMA62A-M3/61?

A: The P4SMA62A from Eaton maintains the same voltage ratings and clamping characteristics. The peak pulse current is marginally higher at 4.8A versus 4.7A. The operating temperature range is narrower (-55°C to 150°C versus -65°C to 150°C). Both use DO-214AC SMA packaging and are compliant with RoHS standards.

Q: Why is P4SMA6.8A listed as a substitute but not recommended?

A: P4SMA6.8A operates in a different voltage class (5.8V reverse standoff versus 53V). This part is designed for low-voltage transient protection applications and is not electrically compatible with circuits requiring 53V protection levels. The significantly higher peak pulse current (40A) indicates a different application category.

Q: Are all substitute parts available in the same package?

A: Yes. All equivalent and substitute parts use DO-214AC SMA surface-mount packaging. Packaging configurations (Tape & Reel versus Cut Tape) may vary, but the physical component package remains consistent for PCB assembly compatibility.

Q: What compliance certifications should I verify when selecting a substitute?

A: All recommended substitute parts maintain RoHS compliance (ROHS3 or RoHS Compliant). All parts are REACH Unaffected and classified as EAR99 for export purposes. Moisture Sensitivity Level (MSL) is 1 (Unlimited) across all parts, indicating no special moisture handling requirements.
