Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4SMA47CA-M3/61 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 40.2V
• Voltage - Breakdown (Min): 44.7V
• Voltage - Clamping (Max) @ Ipp: 64.8V
• Current - Peak Pulse (10/1000µs): 6.2A minimum
• Power - Peak Pulse: 400W

Mechanical Parameters (Must Match):

• Package / Case: DO-214AC or SMA
• Mounting Type: Surface Mount
• Bidirectional Channels: 1

Compliance Parameters:

• RoHS Status: RoHS3 or RoHS Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts maintain these electrical and mechanical specifications within the allowed tolerances for direct circuit board replacement.

Parameter Comparison

Engineering Selection Recommendations

P4SMA47CA-E3/61 (Vishay): Direct substitute with identical electrical specifications and operating temperature range. Both parts are ROHS3 compliant and Active status. Packaging designation differs (E3/61 vs. M3/61) but both use DO-214AC SMA package. This part is suitable for direct replacement in existing designs.

P4SMA47CA (Eaton): Functionally equivalent substitute with matching voltage and power specifications. Peak pulse current is 6.3A versus 6.2A, providing equivalent or superior performance. Operating temperature minimum is -55°C versus -65°C, which may limit use in extreme cold environments. RoHS compliant status is confirmed. This part is suitable for applications where the -55°C minimum temperature is acceptable.

All substitute parts maintain Active product status and unlimited moisture sensitivity level (MSL 1), ensuring long-term availability and handling compatibility.

Frequently Asked Questions (FAQ)

Q: Can P4SMA47CA-E3/61 be used as a direct replacement for P4SMA47CA-M3/61?

A: Yes. Both parts are manufactured by Vishay, share identical electrical parameters (40.2V standoff, 64.8V clamping, 6.2A peak pulse), and use the same DO-214AC SMA package. The packaging designation suffix differs but does not affect electrical or mechanical compatibility.

Q: What is the difference between the Vishay and Eaton versions?

A: The Eaton P4SMA47CA has a slightly higher peak pulse current (6.3A vs. 6.2A) and a narrower operating temperature range (-55 to 150°C vs. -65 to 150°C). All other electrical specifications and the DO-214AC SMA package are identical. The Eaton part is suitable for applications not requiring operation below -55°C.

Q: Are all substitute parts RoHS compliant?

A: Yes. P4SMA47CA-E3/61 is ROHS3 compliant. P4SMA47CA (Eaton) is RoHS compliant. Both meet regulatory requirements for lead-free manufacturing.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts use the DO-214AC SMA surface mount package with identical pinout and footprint. No PCB layout modifications are required for substitution.

Q: What applications are these parts rated for?

A: P4SMA47CA-M3/61 and P4SMA47CA-E3/61 are rated for general-purpose transient voltage suppression. P4SMA47CA (Eaton) is rated for telecom applications. All three are suitable for general-purpose TVS applications.

Q: Is there a difference in moisture sensitivity between these parts?

A: No. All three parts have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity and no special storage or handling requirements.
