SS2003M-TL-E Equivalent & Substitute Parts

Part Overview

The SS2003M-TL-E is a Schottky diode manufactured by onsemi, rated for 30 V DC reverse voltage and 2 A average rectified current in a 6-MCPH surface mount package. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain electrical performance within the specified parameter ranges while accommodating available packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS2003M-TL-E is determined by the following electrical and mechanical criteria:

Mandatory Matching Parameters:

• Technology: Schottky diode
• Voltage - DC Reverse (Vr) (Max): 30 V minimum
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

Current Rating Consideration: The SS2003M-TL-E is rated for 2 A average rectified current. Substitute parts with lower current ratings (1 A or below) operate within reduced current capacity and must be evaluated for application-specific current requirements.

Package Compatibility: The original 6-MCPH package differs from alternative surface mount packages. Physical dimensions, lead configuration, and PCB footprint requirements must be assessed during component substitution.

Parameter Comparison

Engineering Selection Recommendations

SS13HE Substitution Criteria:

The SS13HE is electrically compatible with the SS2003M-TL-E for applications where the reduced current rating of 1 A is acceptable. Both components share identical 30 V reverse voltage ratings, Schottky technology classification, and ROHS3 compliance status.

Electrical Differences:

• The SS13HE operates at a higher forward voltage (550 mV @ 1 A versus 400 mV @ 2 A), resulting in increased power dissipation at equivalent current levels.
• Reverse recovery time is significantly faster (5.6 ns versus 20 ns), providing improved switching performance in high-frequency applications.
• Operating temperature range extends to 150°C, compared to 125°C for the SS2003M-TL-E.

Mechanical Differences:

• Package transition from 6-MCPH to SOD-323HE requires PCB footprint redesign and layout modification.
• The 2-SMD configuration differs substantially from the 6-SMD flat lead package.

Compliance Status: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution in compliant applications.

Frequently Asked Questions (FAQ)

Q: Can the SS13HE directly replace the SS2003M-TL-E without circuit modification?

A: Direct replacement requires current rating verification. The SS13HE is rated for 1 A average rectified current, compared to 2 A for the SS2003M-TL-E. Applications drawing sustained currents above 1 A require circuit redesign or alternative component selection. Package differences necessitate PCB layout modification.

Q: What is the impact of the higher forward voltage in the SS13HE?

A: The SS13HE exhibits 550 mV forward voltage at 1 A, compared to 400 mV at 2 A for the SS2003M-TL-E. In circuits where forward voltage drop directly affects performance, this 150 mV differential at reduced current must be evaluated for voltage regulation, efficiency, and thermal management implications.

Q: Are both components suitable for new design implementations?

A: The SS2003M-TL-E is classified as obsolete and unsuitable for new designs. The SS13HE carries a "Not For New Designs" status, indicating limited availability and manufacturer support. New designs should evaluate current-generation Schottky diode alternatives from the onsemi product portfolio.

Q: What are the package compatibility considerations?

A: The SS2003M-TL-E uses a 6-MCPH package with six leads, while the SS13HE employs a SOD-323HE package with two leads. These packages have different physical dimensions, lead spacing, and PCB footprints. Component substitution requires complete PCB redesign and validation of thermal and electrical performance in the new package configuration.

Q: Do both components meet current regulatory compliance requirements?

A: Both the SS2003M-TL-E and SS13HE are ROHS3 compliant and REACH unaffected, satisfying current regulatory standards for electronic component use in regulated markets.
