Substitute Part Grouping Explanation

Substitution of the SS8P3L-E3/87A is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 30 V
Current - Average Rectified (Io): 8 A
Voltage - Forward (Vf) (Max) @ If: 570 mV @ 8 A
Package / Case: TO-277, 3-PowerDFN
Technology: Schottky
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Parametric Equivalent Parts (SS8P3L-M3/86A, SS8P3L-M3/87A, SS8P3LHM3_A/H, SS8P3LHM3_A/I) maintain identical electrical specifications and package configuration. These parts differ in product status (active versus obsolete) and packaging format (Tape & Reel). The automotive-grade variants (SS8P3LHM3_A/H and SS8P3LHM3_A/I) include AEC-Q101 qualification.

Manufacturer Recommended Part (PMEG030V030EPDZ) from Nexperia USA Inc. operates at the same 30 V reverse voltage rating but with reduced current capacity (3 A versus 8 A) and different forward voltage characteristics (450 mV @ 3 A). This part is suitable only for applications where the 3 A current rating is sufficient.

Engineering Selection Recommendations

For Direct Replacement (Full Electrical Equivalence):

Select SS8P3L-M3/87A or SS8P3L-M3/86A for applications requiring identical electrical performance to the obsolete SS8P3L-E3/87A. Both parts maintain the 8 A current rating, 30 V reverse voltage, and 570 mV forward voltage specification. These Vishay components are active products available in Tape & Reel packaging format.

For Automotive Applications with Enhanced Qualification:

Select SS8P3LHM3_A/H or SS8P3LHM3_A/I when AEC-Q101 automotive qualification is required. These parts provide identical electrical specifications to the main part while meeting automotive-grade standards. SS8P3LHM3_A/H offers higher inventory availability (1364 Pcs) compared to SS8P3LHM3_A/I (925 Pcs).

For Current-Limited Applications:

The PMEG030V030EPDZ from Nexperia is suitable only for applications where the average rectified current requirement does not exceed 3 A. This part offers improved reverse leakage characteristics (150 µA versus 200 µA) and higher maximum junction temperature (175°C versus 150°C). The forward voltage at rated current is lower (450 mV @ 3 A), resulting in reduced power dissipation in current-limited circuits.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental regulatory profile of the original component. Moisture sensitivity level remains at MSL 1 (Unlimited) across all options.

Frequently Asked Questions (FAQ)

Q: Can SS8P3L-M3/87A be used as a direct replacement for SS8P3L-E3/87A?

A: Yes. The SS8P3L-M3/87A is a parametric equivalent with identical electrical specifications: 30 V reverse voltage, 8 A average rectified current, 570 mV forward voltage at 8 A, and TO-277A package configuration. The primary difference is product status (active versus obsolete) and packaging format (Tape & Reel).

Q: What is the difference between SS8P3L-M3/86A and SS8P3L-M3/87A?

A: Both parts are parametric equivalents with identical electrical and thermal specifications. The suffix designation (-86A versus -87A) indicates different manufacturing or packaging variants within the Vishay product line. Selection between these parts depends on availability and procurement requirements.

Q: Are the automotive-grade variants (SS8P3LHM3_A/H and SS8P3LHM3_A/I) suitable for non-automotive applications?

A: Yes. Automotive-grade components with AEC-Q101 qualification exceed the requirements of standard industrial applications. These parts maintain identical electrical specifications and can be used in any application where the standard-grade equivalents are specified.

Q: Can PMEG030V030EPDZ replace the SS8P3L-E3/87A in all applications?

A: No. The PMEG030V030EPDZ is rated for 3 A average rectified current, compared to 8 A for the SS8P3L-E3/87A. This part is suitable only for applications where the circuit current requirement does not exceed 3 A. The 30 V reverse voltage rating and fast recovery speed are equivalent.

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

A: Substitution compatibility is determined by: (1) Voltage - DC Reverse (Vr) rating of 30 V, (2) Current - Average Rectified (Io) capacity of 8 A (or lower if application permits), (3) Forward voltage characteristics, (4) TO-277A package configuration, and (5) Fast Recovery Schottky technology. Deviations in any of these parameters require circuit re-evaluation.

Q: Is the capacitance specification relevant for substitution?

A: The capacitance specification (330pF @ 4V, 1MHz for Vishay parts; 495pF @ 1V, 1MHz for Nexperia) is provided for the substitute parts but not specified for the obsolete SS8P3L-E3/87A. Applications sensitive to junction capacitance should evaluate the specific values provided for each substitute option.

Q: What is the significance of the -55°C to 150°C operating temperature range?

A: This range defines the maximum junction temperature limits for reliable operation. The PMEG030V030EPDZ extends to 175°C maximum, providing additional thermal margin in high-temperature environments. For applications operating within -55°C to 150°C, all substitute options are thermally compatible.

Q: Are all substitute parts available in the same packaging format?

A: All Vishay substitute parts (SS8P3L-M3/86A, SS8P3L-M3/87A, SS8P3LHM3_A/H, SS8P3LHM3_A/I) are supplied in Tape & Reel format. The PMEG030V030EPDZ from Nexperia is also supplied in Tape & Reel format. The TO-277A (SMPC) package configuration is identical across all options.
