Parameter Comparison

Engineering Selection Recommendations

MSS1P2L-M3/89A is a direct parametric equivalent available in Active product status. This part maintains all electrical specifications and physical package compatibility with the obsolete MSS1P2L-E3/89A. The primary distinction is packaging format: MSS1P2L-M3/89A is supplied in Cut Tape (CT) and Digi-Reel® configurations, whereas the original part was supplied in standard packaging. This substitute is suitable for direct replacement in production environments requiring standard tape and reel delivery.

MSS1P2LHM3_A/H is an Active product variant that meets all parametric requirements of the MSS1P2L-E3/89A. This part includes automotive-grade qualification (AEC-Q101) and provides additional capacitance specification (65 pF @ 4 V, 1 MHz). Selection of this variant is appropriate for applications requiring automotive-grade reliability and traceability, or where the additional capacitance specification provides design margin.

Both substitute parts carry ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the original part. Product status transition from Obsolete to Active ensures long-term supply availability and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can MSS1P2L-M3/89A be used as a direct replacement for MSS1P2L-E3/89A?

A: Yes. MSS1P2L-M3/89A is a parametric equivalent with identical electrical specifications (20 V reverse voltage, 1 A average rectified current, 500 mV forward voltage drop, fast recovery characteristics) and identical MicroSMP (DO-219AD) package. The primary difference is packaging format (Cut Tape and Digi-Reel versus standard packaging). Electrical performance and physical compatibility are equivalent.

Q: What is the difference between MSS1P2L-M3/89A and MSS1P2LHM3_A/H?

A: Both parts meet the core electrical specifications of the MSS1P2L-E3/89A. MSS1P2LHM3_A/H includes automotive-grade qualification (AEC-Q101) and specifies capacitance at 65 pF @ 4 V, 1 MHz. Selection depends on application requirements: standard industrial applications may use MSS1P2L-M3/89A, while automotive or high-reliability applications benefit from the AEC-Q101 qualification of MSS1P2LHM3_A/H.

Q: Are all three parts in the same physical package?

A: Yes. All three parts use the MicroSMP (DO-219AD) surface mount package. Physical dimensions and PCB footprint compatibility are identical, enabling direct board-level substitution without layout modifications.

Q: Why is the original MSS1P2L-E3/89A marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. MSS1P2L-M3/89A and MSS1P2LHM3_A/H are Active products with identical or superior specifications, ensuring continued availability and manufacturing support for applications requiring this diode specification.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected. Regulatory and environmental compliance profiles are identical across the main part and both substitutes.

Q: Can MSS1P2LHM3_A/H be used in non-automotive applications?

A: Yes. MSS1P2LHM3_A/H meets all electrical and package specifications required for the MSS1P2L-E3/89A. The automotive-grade qualification (AEC-Q101) and additional capacitance specification represent enhanced performance characteristics that are compatible with standard industrial applications. No design modifications are required.
