Engineering Selection Recommendations

Primary Substitutes (Standard Grade, Active Status):

ES1PC-M3/85A and ES1PC-M3/84A are direct electrical and mechanical equivalents with active product status. These parts are recommended for applications where standard-grade rectifier diodes are specified. Both parts maintain full electrical parameter equivalence with the obsolete ES1PC-E3/85A and are available in higher inventory quantities.

Automotive-Grade Substitutes (AEC-Q101 Qualified):

ES1PCHM3/85A and ES1PCHM3/84A are automotive-qualified variants carrying AEC-Q101 certification. These parts maintain identical electrical and mechanical specifications while meeting automotive industry qualification standards. Selection of automotive-grade variants is required for applications subject to automotive reliability and qualification requirements.

Product Status Consideration:

The ES1PC-E3/85A is classified as obsolete. All listed substitute parts are active products, ensuring long-term availability and continued manufacturing support. Transition to an active part number is recommended for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Can ES1PC-M3/85A be used as a direct replacement for ES1PC-E3/85A?

A: Yes. ES1PC-M3/85A is electrically and mechanically equivalent to ES1PC-E3/85A. Both parts share identical voltage ratings (150 V), current ratings (1 A), forward voltage characteristics (920 mV @ 1 A), reverse recovery time (25 ns), and package specifications (DO-220AA SMP). The primary difference is product status: ES1PC-M3/85A is active while ES1PC-E3/85A is obsolete.

Q: What is the difference between ES1PC-M3/85A and ES1PCHM3/85A?

A: Both parts are electrically and mechanically identical. The distinction is in qualification grade: ES1PC-M3/85A is standard-grade, while ES1PCHM3/85A carries automotive-grade qualification with AEC-Q101 certification. Selection depends on application requirements. Automotive applications requiring AEC-Q101 qualification must use the ES1PCHM3/85A variant.

Q: Are the "/85A" and "/84A" suffixes interchangeable?

A: Yes, from an electrical and mechanical standpoint. Both suffix variants (ES1PC-M3/85A and ES1PC-M3/84A, as well as ES1PCHM3/85A and ES1PCHM3/84A) maintain identical electrical parameters and package specifications. The suffix designation reflects internal manufacturing or tape configuration differences that do not affect component performance or interchangeability.

Q: Is the DO-220AA package compatible with existing PCB layouts designed for ES1PC-E3/85A?

A: Yes. All substitute parts use the DO-220AA (SMP) surface mount package, which is identical to the original ES1PC-E3/85A package. PCB footprints, solder pad layouts, and mounting procedures remain unchanged.

Q: What compliance certifications apply to these substitute parts?

A: All listed parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Standard-grade parts (ES1PC-M3/85A and ES1PC-M3/84A) meet general industrial compliance. Automotive-grade parts (ES1PCHM3/85A and ES1PCHM3/84A) additionally carry AEC-Q101 automotive qualification.

Q: Which substitute part should be selected for new production designs?

A: For standard industrial applications, ES1PC-M3/85A or ES1PC-M3/84A are recommended due to active product status and established availability. For automotive applications, ES1PCHM3/85A or ES1PCHM3/84A are required to meet AEC-Q101 qualification standards.
