Substitute Part Grouping Explanation

Substitution of the MSS1P3L-E3/89A is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 500 mV @ 1 A
• Current - Reverse Leakage @ Vr: 250 µA @ 30 V
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical & Environmental Specifications:

• Package / Case: MicroSMP (DO-219AD)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical performance and environmental ratings. Differences in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and product status (Active versus Obsolete) do not affect functional equivalence. The MSS1P3LHM3_A/H variant includes automotive-grade qualification (AEC-Q101) and is suitable for applications requiring automotive compliance.

Parameter Comparison

Engineering Selection Recommendations

MSS1P3L-M3/89A is the direct functional equivalent with active product status. This part maintains all electrical and mechanical specifications of the obsolete MSS1P3L-E3/89A while offering superior availability through standard Cut Tape and Digi-Reel® packaging formats. Selection of this part is appropriate for general industrial applications requiring 30 V, 1 A Schottky rectification in MicroSMP surface mount packages.

MSS1P3LHM3_A/H is the parametric equivalent with automotive-grade qualification. This part is AEC-Q101 qualified and carries automotive-grade designation, making it suitable for applications subject to automotive industry standards and requirements. All electrical and thermal specifications remain identical to the main part. Selection of this variant is required for automotive applications or designs requiring automotive-grade component certification.

Both substitute parts are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard surface mount assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can MSS1P3L-M3/89A be used as a direct replacement for MSS1P3L-E3/89A?

A: Yes. MSS1P3L-M3/89A is a direct functional equivalent. Both parts share identical electrical specifications (30 V reverse voltage, 1 A average rectified current, 500 mV forward voltage at 1 A), identical reverse leakage characteristics (250 µA @ 30 V), identical fast recovery speed (≤ 500ns), and identical MicroSMP (DO-219AD) surface mount packaging. The primary difference is product status: MSS1P3L-M3/89A is active with improved availability.

Q: What is the difference between MSS1P3L-M3/89A and MSS1P3LHM3_A/H?

A: Both parts are parametric equivalents with identical electrical and thermal performance. MSS1P3LHM3_A/H carries automotive-grade designation and AEC-Q101 qualification, making it suitable for automotive applications. MSS1P3L-M3/89A is the standard industrial-grade variant. Selection depends on application requirements: use MSS1P3L-M3/89A for general industrial applications and MSS1P3LHM3_A/H for automotive or automotive-qualified designs.

Q: Are there packaging differences between the substitute parts?

A: Yes. MSS1P3L-M3/89A is supplied in Cut Tape (CT) and Digi-Reel® formats. MSS1P3LHM3_A/H is supplied in Tape & Reel (TR) format. Both packaging formats are standard for surface mount assembly. The MicroSMP (DO-219AD) package itself is identical across all three parts, ensuring PCB footprint and reflow compatibility.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts use identical MicroSMP (DO-219AD) surface mount packages with identical footprints, pin configurations, and thermal characteristics. PCB layout, solder pad dimensions, and reflow profiles require no modification when substituting between these parts.

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

A: MSL 1 indicates unlimited shelf life under standard storage conditions (≤ 30°C, ≤ 85% relative humidity). These parts do not require special moisture-controlled storage or baking procedures prior to assembly, simplifying inventory management and reducing handling complexity.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MSS1P3L-E3/89A, MSS1P3L-M3/89A, and MSS1P3LHM3_A/H are all ROHS3 compliant, confirming compliance with Restriction of Hazardous Substances regulations and suitability for applications subject to RoHS requirements.

Q: What is the operating temperature range for these diodes?

A: The junction operating temperature range is -55°C to 150°C for all three parts. This range covers standard industrial and automotive temperature environments. Verify that application-specific thermal management and PCB design accommodate the maximum junction temperature under worst-case operating conditions.
