SK26-TP Equivalent & Substitute Parts

Part Overview

The SK26-TP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 60V DC reverse voltage and 2A average rectified current in a DO-214AA (SMB) surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The SK26-TP is RoHS3 compliant and suitable for fast recovery rectification applications requiring low forward voltage drop characteristics.

Substitute Part Grouping Explanation

Substitution of the SK26-TP is determined by strict equivalence across the following critical parameters: Schottky technology classification, 60V maximum reverse voltage rating, 2A average rectified current capacity, 700mV maximum forward voltage at 2A, fast recovery speed characteristic (≤500ns for currents >200mA), and DO-214AA/SMB surface mount package compatibility. All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional interchangeability within the original application circuit.

Substitute parts are grouped into two categories: parametric equivalents (identical electrical performance across all specified parameters) and similar parts (meeting all critical electrical requirements with minor variations in secondary characteristics such as reverse leakage current or capacitance values that do not affect primary rectification function).

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the SK26-TP across the critical parameters of voltage rating, current capacity, forward voltage drop, recovery speed, and package form factor. Selection among active alternatives should be based on the following factors:

Product Status and Availability: The SK26-TP is obsolete. Active alternatives include SK26-LTP, SK26HE3-LTP, SS26B-HF, SS26B, B260-13-F, CMSH2-60 TR13 PBFREE, and SS26-E3/52T. These parts are currently in production and available through standard procurement channels.

Compliance and Certification: All substitute parts are RoHS3 compliant and REACH unaffected, matching the original part's regulatory status. SK26HE3-LTP carries AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade reliability.

Packaging Format: Substitute parts are available in both Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) formats. Selection should align with assembly line requirements and procurement volume specifications.

Reverse Leakage Current: Reverse leakage varies among substitutes (100µA to 1mA at 60V). SK26HE3-LTP offers the lowest leakage at 100µA, while SK26-LTP exhibits 1mA leakage. For applications sensitive to leakage current, SK26HE3-LTP or SS26-E3/52T (400µA) are preferred.

Operating Temperature Range: Most substitutes support -55°C to 125°C or -65°C to 150°C junction temperature ranges. B260-13-F and CMSH2-60 TR13 PBFREE extend to 150°C maximum, providing additional thermal margin for high-temperature applications.

Frequently Asked Questions (FAQ)

Q: Can SK26-LTP directly replace SK26-TP in existing designs?

A: Yes. SK26-LTP is a parametric equivalent manufactured by the same supplier (Micro Commercial Co) with identical electrical specifications: 60V reverse voltage, 2A current rating, 700mV forward voltage, and fast recovery characteristics. The primary difference is packaging format (Tape & Reel versus Cut Tape) and higher reverse leakage current (1mA versus 500µA). For most applications, this leakage difference is not functionally significant.

Q: What is the difference between SK26HE3-LTP and SK26-LTP?

A: Both parts share the same base electrical ratings (60V, 2A, 700mV Vf). SK26HE3-LTP differs in three aspects: (1) lower reverse leakage current at 100µA versus 1mA, (2) higher capacitance at 230pF versus 50pF, and (3) AEC-Q101 automotive qualification. SK26HE3-LTP is suitable for automotive and high-reliability applications where leakage current must be minimized.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the DO-214AA (SMB) surface mount package, ensuring mechanical and thermal compatibility. However, packaging format (Cut Tape, Digi-Reel, or Tape & Reel) varies by manufacturer and part number. Verify packaging format matches assembly requirements before procurement.

Q: Which substitute part has the lowest reverse leakage current?

A: SK26HE3-LTP exhibits the lowest reverse leakage at 100µA @ 60V. SS26-E3/52T follows at 400µA. If leakage current is a critical design parameter, these parts are preferred over alternatives rated at 500µA or 1mA.

Q: Can I use B260-13-F as a substitute for SK26-TP?

A: Yes. B260-13-F (Diodes Incorporated) meets all critical electrical specifications: 60V reverse voltage, 2A current, 700mV forward voltage, and fast recovery speed. It is RoHS3 compliant and available in Cut Tape & Digi-Reel packaging. Operating temperature range extends to 150°C, providing additional thermal capability compared to the original part.

Q: What is the significance of the "HE3" designation in SK26HE3-LTP?

A: The HE3 designation indicates automotive-grade qualification (AEC-Q101) and enhanced performance characteristics, specifically lower reverse leakage current (100µA) and higher capacitance (230pF). This part is suitable for automotive and mission-critical applications requiring higher reliability standards.

Q: Are there any differences in RoHS compliance between substitute parts?

A: All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the original SK26-TP regulatory status. No compliance differences exist among the alternatives.

Q: Which substitute part offers the best availability?

A: SS26-E3/52T (Vishay) and B260-13-F (Diodes Incorporated) show the highest inventory levels at 24,539 and 44,287 pieces respectively. These parts are suitable for high-volume procurement requirements.
