Substitute Part Grouping Explanation

Substitution of the ESH2PC-E3/85A is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

Voltage - DC Reverse (Vr) (Max): 150 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 980 mV @ 2 A
Reverse Recovery Time (trr): 25 ns
Current - Reverse Leakage @ Vr: 1 µA @ 150 V
Capacitance @ Vr, F: 25 pF @ 4V, 1MHz
Package / Case: DO-220AA

Engineering Selection Recommendations

ESH2PC-M3/85A is the primary direct substitute for the obsolete ESH2PC-E3/85A. This part maintains identical electrical specifications and is supplied in Tape & Reel packaging format. Product status is Active, ensuring long-term availability and supply chain continuity.

ESH2PC-M3/84A provides parametric equivalence with identical electrical performance. This part is supplied in Tape & Reel packaging and carries Active product status. Inventory availability is significantly higher than alternative options.

ESH2PCHM3/84A and ESH2PCHM3/85A are automotive-grade variants qualified to AEC-Q101 standard. These parts are suitable for applications requiring automotive-level reliability and traceability. ESH2PCHM3/84A is supplied in Cut Tape format, while ESH2PCHM3/85A is supplied in Tape & Reel format. Both carry Active product status.

Selection between standard-grade and automotive-grade variants depends on application requirements and end-use classification. All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can ESH2PC-M3/85A be used as a direct replacement for ESH2PC-E3/85A?

A: Yes. ESH2PC-M3/85A is electrically and mechanically equivalent to ESH2PC-E3/85A across all critical parameters including voltage rating, current rating, forward voltage drop, reverse recovery time, leakage current, and package configuration. The primary difference is product status: ESH2PC-M3/85A is Active while ESH2PC-E3/85A is Obsolete.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specified lengths, suitable for lower-volume or manual assembly operations. Electrical performance is identical between packaging formats.

Q: Are automotive-grade variants (ESH2PCHM3/84A and ESH2PCHM3/85A) suitable for non-automotive applications?

A: Yes. Automotive-grade variants with AEC-Q101 qualification meet or exceed the electrical and reliability requirements of standard-grade parts. These variants are suitable for any application where the ESH2PC-E3/85A was originally specified.

Q: What does AEC-Q101 qualification indicate?

A: AEC-Q101 is an automotive industry standard qualification for discrete semiconductors. Parts carrying this qualification have undergone additional testing and validation to meet automotive reliability and traceability requirements. AEC-Q101 qualified parts are suitable for automotive and high-reliability applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance status, indicating conformance to Restriction of Hazardous Substances regulations.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity rating?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. Standard moisture bake-out procedures are not required prior to soldering.

Q: Can I mix different substitute parts in the same production batch?

A: Yes. All substitute parts maintain identical electrical specifications and package configuration. Mixing different part numbers within a single design is electrically valid. However, procurement and traceability documentation should reflect the specific part numbers used.
