Engineering Selection Recommendations

Direct Replacement (Same Electrical and Mechanical Specifications):

SS1P4L-M3/84A and SS1P4LHM3/85A are the primary active alternatives to the obsolete SS1P4L-E3/85A. Both maintain identical electrical parameters (40 V, 1.5 A, 480 mV forward voltage, 150 µA reverse leakage) and use the same DO-220AA package. SS1P4L-M3/84A is available in Cut Tape packaging with 1501 units in stock. SS1P4LHM3/85A is available in Tape & Reel packaging with 10050 units in stock and includes AEC-Q101 automotive qualification.

Automotive-Grade Alternatives:

SS1P4LHE3/84A and SS1P4LHM3/84A are automotive-qualified variants (AEC-Q100 and AEC-Q101 respectively) with identical electrical specifications and DO-220AA packaging. These parts are suitable for applications requiring automotive-grade components. SS1P4LHM3/84A offers the highest inventory availability at 24200 units.

Current-Reduced Alternative:

SS1P4L-M3/85A is rated for 1 A average rectified current (versus 1.5 A for the main part) but maintains all other electrical parameters and uses the same DO-220AA package. This part is suitable for applications where the 1.5 A rating is not required and offers 10219 units in stock.

Different Package Alternative:

PMEG4010ETR,115 from Nexperia USA Inc. is a 40 V, 1 A Schottky diode in SOD-123W package. This part has a lower reverse leakage current (50 µA versus 150 µA) and faster reverse recovery time (4.4 ns specified). The SOD-123W package is mechanically incompatible with DO-220AA and requires PCB layout modification. This part is suitable only when package change is acceptable.

All recommended substitutes maintain ROHS3 compliance, MSL 1 rating, and support the -55°C to 150°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can SS1P4L-M3/85A be used as a direct replacement for SS1P4L-E3/85A?

A: SS1P4L-M3/85A is electrically compatible but has a reduced current rating of 1 A versus 1.5 A. It is suitable only for applications where the circuit current does not exceed 1 A. For applications requiring the full 1.5 A rating, use SS1P4L-M3/84A or SS1P4LHM3/85A instead.

Q: What is the difference between SS1P4L-M3/84A and SS1P4LHM3/84A?

A: Both parts have identical electrical specifications (40 V, 1.5 A, 480 mV forward voltage). SS1P4LHM3/84A includes automotive qualification (AEC-Q101) and is suitable for automotive applications. SS1P4L-M3/84A is a standard industrial-grade part. Both use DO-220AA packaging and are available in Cut Tape format.

Q: Can PMEG4010ETR,115 replace SS1P4L-E3/85A in existing designs?

A: PMEG4010ETR,115 has different electrical characteristics (1 A versus 1.5 A, 490 mV versus 480 mV forward voltage, 50 µA versus 150 µA reverse leakage) and uses SOD-123W package instead of DO-220AA. This part requires PCB layout modification and is not a pin-compatible substitute. Use only if design specifications allow for these changes.

Q: What packaging options are available for the active substitutes?

A: Active Vishay substitutes are available in Tape & Reel (TR) and Cut Tape (CT) packaging formats. SS1P4L-M3/85A is available in TR format. SS1P4L-M3/84A and SS1P4LHM3/84A are available in CT format. SS1P4LHM3/85A is available in TR format. Select packaging based on production volume and assembly requirements.

Q: Are the automotive-qualified variants (SS1P4LHE3/84A, SS1P4LHM3/84A, SS1P4LHM3/85A) suitable for non-automotive applications?

A: Yes. Automotive-qualified parts meet or exceed industrial-grade specifications and are fully compatible with non-automotive applications. These parts offer additional qualification benefits and higher reliability margins.

Q: What is the inventory status of available substitutes?

A: SS1P4LHM3/84A has the highest inventory at 24200 units. SS1P4LHM3/85A has 10050 units. SS1P4L-M3/85A has 10219 units. SS1P4L-M3/84A has 1501 units. PMEG4010ETR,115 has 37639 units. All parts are listed as new original stock.

Q: Do all substitutes maintain the same operating temperature range?

A: Yes. All Vishay substitutes (SS1P4L-M3/85A, SS1P4L-M3/84A, SS1P4LHE3/84A, SS1P4LHM3/84A, SS1P4LHM3/85A) support -55°C to 150°C junction temperature range. PMEG4010ETR,115 supports up to 175°C maximum junction temperature.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All recommended substitutes are ROHS3 compliant and have MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original SS1P4L-E3/85A.
