SS5P4-M3/87A Equivalent & Substitute Parts

Part Overview

The SS5P4-M3/87A is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 40 V DC reverse voltage and 5 A average rectified current. The device is packaged in a surface mount TO-277A (SMPC) configuration and is part of the eSMP® series. This component is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameters. Alternative sources and packaging configurations may be required due to inventory availability, supply chain considerations, or specific application requirements such as automotive qualification.

Engineering Selection Recommendations

Primary Substitutes (Vishay Manufacturer):

SS5P4-M3/86A is a direct electrical equivalent differing only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Selection between SS5P4-M3/87A and SS5P4-M3/86A depends on assembly line requirements and packaging compatibility with automated placement equipment.

SS5P4HM3_A/H and SS5P4HM3_A/I are electrically equivalent variants with automotive qualification (AEC-Q101). These parts are suitable for applications requiring automotive-grade components and maintain identical electrical performance specifications.

Alternative Manufacturer Substitutes:

FSV540 (onsemi) maintains full electrical equivalence but carries "Not For New Designs" product status. This part is suitable for legacy system support and field replacements where existing inventory exists, but should not be selected for new product development.

SV540_R2_00001 (Panjit International Inc.) is electrically equivalent and carries Active product status. This part provides an alternative source option with equivalent performance characteristics.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and REACH unaffected status. Selection among substitutes should prioritize Active product status for new designs. Automotive-qualified variants (SS5P4HM3_A/H, SS5P4HM3_A/I) are required for applications subject to automotive standards.

Frequently Asked Questions (FAQ)

Q: Can SS5P4-M3/86A be used as a direct replacement for SS5P4-M3/87A?

A: Yes. Both parts are electrically identical with matching voltage, current, and thermal specifications. The difference is packaging format: SS5P4-M3/87A is supplied in Tape & Reel (TR) format, while SS5P4-M3/86A is supplied in Cut Tape (CT) & Digi-Reel® format. Compatibility depends on your assembly equipment's tape format compatibility.

Q: What is the difference between SS5P4HM3_A/H and SS5P4-M3/87A?

A: Both parts are electrically equivalent with identical voltage (40 V), current (5 A), and forward voltage (520 mV @ 5 A) specifications. SS5P4HM3_A/H carries automotive qualification (AEC-Q101) and is designated as an automotive-grade component. Select SS5P4HM3_A/H for applications requiring automotive compliance; otherwise, both parts are functionally interchangeable.

Q: Why is FSV540 marked "Not For New Designs"?

A: FSV540 is electrically equivalent to SS5P4-M3/87A but carries a "Not For New Designs" product status from onsemi. This designation indicates the manufacturer is phasing out this part number. FSV540 remains suitable for field replacements and legacy system support but should not be selected for new product development. Use SS5P4-M3/87A or alternative Active-status parts for new designs.

Q: Are all substitute parts in the same TO-277 package?

A: Yes. All substitute parts use the TO-277, 3-PowerDFN package configuration and are surface mount devices. They are mechanically compatible with PCB layouts designed for the SS5P4-M3/87A.

Q: What is the inventory status of substitute parts?

A: Inventory levels vary by part number and supplier. SS5P4HM3_A/H has the highest inventory (86,100 pcs), while SV540_R2_00001 has the lowest (4,074 pcs). Verify current availability with your component supplier for time-sensitive applications.

Q: Can I use SV540_R2_00001 (Panjit) instead of Vishay parts?

A: Yes. SV540_R2_00001 is electrically equivalent with matching electrical specifications and Active product status. It provides an alternative manufacturer source. Verify that your application does not have manufacturer-specific requirements before substitution.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in: reverse voltage (40 V), average rectified current (5 A), forward voltage (520 mV @ 5 A), recovery speed (≤ 500ns), reverse leakage current (250 µA @ 40 V), operating temperature range (-55°C to 150°C), and package type (TO-277, 3-PowerDFN surface mount). All identified substitutes meet these criteria.
