SS1P5L-E3/85A Equivalent & Substitute Parts

Part Overview

The SS1P5L-E3/85A is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 50 V DC reverse voltage and 1 A average rectified current in a DO-220AA surface mount package. This part is classified as obsolete and has been superseded by active production alternatives within the same eSMP® series. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production builds and design revisions.

Substitute Part Grouping Explanation

Substitution of the SS1P5L-E3/85A is determined by electrical and mechanical parameter equivalence within the eSMP® series. All substitute parts maintain identical electrical specifications: 50 V reverse voltage rating, 1 A average rectified current, 590 mV forward voltage drop at 1 A, fast recovery switching characteristics, and 100 µA reverse leakage current at rated voltage. All substitutes use the same DO-220AA surface mount package and operate across the identical temperature range of -55°C to 150°C.

The primary distinction among substitute parts relates to product status (active versus obsolete), packaging format (bulk versus tape and reel), and automotive qualification level. The SS1P5L-M3/85A and SS1P5L-M3/84A are direct electrical equivalents supplied in tape and reel packaging with active product status. The SS1P5LHM3/84A and SS1P5LHM3/85A variants include automotive-grade qualification to AEC-Q101 standard, making them suitable for applications requiring automotive component certification.

Engineering Selection Recommendations

For applications requiring immediate component availability with active product status, the SS1P5L-M3/85A and SS1P5L-M3/84A are direct electrical equivalents to the obsolete SS1P5L-E3/85A. Both parts maintain identical electrical performance and are supplied in tape and reel packaging suitable for automated assembly processes.

For automotive applications or designs requiring AEC-Q101 qualification, the SS1P5LHM3/84A and SS1P5LHM3/85A are the appropriate selections. These variants carry automotive-grade designation and meet AEC-Q101 qualification standards while maintaining all electrical and thermal specifications of the standard-grade alternatives.

All substitute parts are ROHS3 compliant and REACH unaffected, ensuring regulatory compliance equivalent to the original part. Selection between the /84A and /85A suffix variants should be based on specific procurement and supply chain requirements, as both maintain identical electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the SS1P5L-M3/85A directly replace the obsolete SS1P5L-E3/85A in existing designs?

A: Yes. The SS1P5L-M3/85A is electrically and mechanically equivalent to the SS1P5L-E3/85A. Both parts share identical voltage ratings (50 V), current ratings (1 A), forward voltage characteristics (590 mV @ 1 A), switching speed (fast recovery ≤ 500ns), reverse leakage current (100 µA @ 50 V), and operating temperature range (-55°C to 150°C). The primary difference is product status (active versus obsolete) and packaging format (tape and reel versus bulk).

Q: What is the difference between the /84A and /85A suffix designations?

A: The /84A and /85A suffixes represent different manufacturing date codes or tape reel specifications within the same electrical family. Both variants maintain identical electrical performance and are functionally interchangeable for circuit design purposes.

Q: Are the automotive-grade variants (SS1P5LHM3/84A and SS1P5LHM3/85A) suitable for non-automotive applications?

A: Yes. The automotive-grade variants meet all electrical specifications of the standard-grade parts and include additional AEC-Q101 qualification. They can be used in any application where the standard-grade parts are specified, though they may carry different cost implications.

Q: Does the DO-220AA package remain consistent across all substitute parts?

A: Yes. All substitute parts use the DO-220AA surface mount package with identical pin configuration, footprint, and mounting requirements. No PCB layout modifications are required when substituting between these parts.

Q: Are there any thermal or performance differences between the substitute parts?

A: No. All substitute parts operate across the identical junction temperature range (-55°C to 150°C) and maintain the same forward voltage drop, reverse leakage current, and switching characteristics. Thermal performance is equivalent across all variants.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant and REACH unaffected. The automotive-grade variants (SS1P5LHM3/84A and SS1P5LHM3/85A) additionally carry AEC-Q101 qualification.
