SK88L-TP Equivalent & Substitute Parts

Part Overview

The SK88L-TP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 80V DC reverse voltage and 8A average rectified current in a surface mount SMC (DO-214AB) package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. The product status necessitates identification of active equivalent parts to support ongoing maintenance, repair, and legacy system requirements where continued supply of the original component is unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SK88L-TP is determined by electrical and mechanical parameter equivalence within the Schottky rectifier diode category. The primary substitution criteria are:

Electrical Parameters (Critical):

• Voltage - DC Reverse (Vr) (Max): 80 V minimum
• Current - Average Rectified (Io): 8 A minimum
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Critical):

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount

Secondary Parameters (Acceptable Variation):

• Voltage - Forward (Vf) (Max) @ If: Minor variations acceptable within thermal design margins
• Current - Reverse Leakage @ Vr: Acceptable within application leakage budget
• Operating Temperature - Junction: Extended range acceptable for legacy applications

The HSM880J/TR13 manufactured by Microchip Technology meets all critical electrical and mechanical parameters, confirming direct substitution capability for the SK88L-TP in equivalent circuit applications.

Engineering Selection Recommendations

SK88L-TP Status Consideration: The SK88L-TP is designated "Not For New Designs" and carries ROHS3 compliance. This status indicates the component is in end-of-life phase with limited future availability. Current inventory of 4130 pieces represents existing stock only.

HSM880J/TR13 Status Consideration: The HSM880J/TR13 is classified as "Active" product status, indicating ongoing manufacturing and supply chain availability. However, this component is RoHS non-compliant, which may present regulatory constraints in applications subject to RoHS requirements.

Selection Basis:

• For applications requiring RoHS compliance: Continued use of SK88L-TP stock is necessary until depletion, as no RoHS-compliant 80V/8A Schottky alternative is provided in the substitute list.
• For applications without RoHS compliance requirements: HSM880J/TR13 provides active product status with superior electrical characteristics (lower forward voltage drop and reverse leakage current) and extended operating temperature range.
• Both parts are REACH Unaffected and classified under identical HTSUS and ECCN codes.

Frequently Asked Questions (FAQ)

Q: Can HSM880J/TR13 directly replace SK88L-TP in existing designs?

A: Yes. Both components share identical voltage ratings (80V), current ratings (8A), package type (DO-214AB, SMC), and mounting configuration (surface mount). Electrical parameters are compatible within application design margins.

Q: What is the difference in forward voltage drop between these parts?

A: The SK88L-TP specifies 800 mV maximum forward voltage at 8A, while the HSM880J/TR13 specifies 780 mV maximum at 8A. The HSM880J/TR13 exhibits lower forward voltage drop, resulting in reduced power dissipation and improved thermal performance in equivalent circuits.

Q: Are there differences in reverse leakage current?

A: Yes. The SK88L-TP specifies 1 mA reverse leakage at 80V, while the HSM880J/TR13 specifies 500 µA at 80V. The HSM880J/TR13 exhibits lower reverse leakage, which may improve circuit performance in applications sensitive to leakage current.

Q: What is the impact of RoHS compliance differences?

A: The SK88L-TP is ROHS3 compliant; the HSM880J/TR13 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must continue using SK88L-TP stock. Applications without RoHS constraints may use HSM880J/TR13.

Q: Do both parts have identical operating temperature ranges?

A: No. The SK88L-TP operates from -55°C to 150°C junction temperature, while the HSM880J/TR13 operates from -55°C to 175°C. The HSM880J/TR13 provides extended high-temperature capability, suitable for applications requiring operation above 150°C.

Q: Are the packages physically identical?

A: Yes. Both components use the DO-214AB (SMC) surface mount package with identical footprint and land pattern. No PCB layout modifications are required for substitution.

Q: What is the moisture sensitivity level for both parts?

A: Both SK88L-TP and HSM880J/TR13 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
