STPS2H100RL Equivalent & Substitute Parts

Part Overview

The STPS2H100RL is a Schottky rectifier diode manufactured by STMicroelectronics, rated for 100 V DC reverse voltage and 2 A average rectified current in a DO-41 through-hole package. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design requirements and procurement needs. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts satisfy the same functional requirements within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS2H100RL is determined by the following critical parameters:

Electrical Specifications:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Current - Average Rectified (Io): 2 A minimum
• Voltage - Forward (Vf) (Max) @ If: 860 mV maximum at 2 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: ≤ 1 µA @ 100 V

Mechanical Specifications:

• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, Axial

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Parts are grouped into two categories: parametric equivalents (identical specifications) and similar substitutes (equivalent function with minor parameter variations within acceptable design tolerances).

Engineering Selection Recommendations

STPS2H100 (STMicroelectronics): This part is a parametric equivalent to the STPS2H100RL with identical electrical and mechanical specifications. The STPS2H100 maintains active product status, ensuring long-term availability and supply chain continuity. All compliance certifications (ROHS3, REACH Unaffected) are maintained. This part is the primary recommendation for direct replacement in applications requiring the exact specifications of the obsolete STPS2H100RL.

SR2010-TP (Micro Commercial Co): This part functions as a substitute with the following considerations: forward voltage is 10 mV lower (850 mV vs. 860 mV at 2 A), reverse leakage current is 1000 times higher (1 mA vs. 1 µA at 100 V), and maximum junction temperature is 50°C lower (125°C vs. 175°C). The SR2010-TP is suitable for applications where the lower forward voltage and higher reverse leakage are acceptable within circuit design margins. The reduced maximum junction temperature requires thermal design verification for high-temperature applications. All compliance certifications are maintained.

Selection between these parts depends on application-specific requirements regarding reverse leakage current tolerance, forward voltage drop, and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can STPS2H100 directly replace STPS2H100RL? A: Yes. The STPS2H100 is a parametric equivalent with identical voltage rating (100 V), current rating (2 A), forward voltage (860 mV @ 2 A), and package (DO-41). The primary difference is product status: STPS2H100RL is obsolete while STPS2H100 is active.

Q: What are the key differences between SR2010-TP and STPS2H100RL? A: The SR2010-TP has three notable differences: (1) forward voltage is 10 mV lower at 2 A, (2) reverse leakage current is 1 mA instead of 1 µA at 100 V, and (3) maximum junction temperature is 125°C instead of 175°C. Voltage and current ratings remain identical at 100 V and 2 A.

Q: Are all substitute parts in the same package? A: Yes. All parts listed (STPS2H100RL, STPS2H100, and SR2010-TP) use the DO-41 through-hole axial package (DO-204AL designation), ensuring mechanical compatibility in PCB designs.

Q: Do all parts meet RoHS and REACH compliance? A: Yes. STPS2H100RL, STPS2H100, and SR2010-TP are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Which part should be selected for high-temperature applications? A: STPS2H100 or STPS2H100RL are preferred for applications requiring operation up to 175°C junction temperature. SR2010-TP is limited to 125°C maximum junction temperature and requires thermal design verification for elevated-temperature environments.

Q: Is reverse leakage current a critical factor in part selection? A: Reverse leakage current becomes critical in precision analog circuits, low-power applications, and high-impedance signal paths. STPS2H100 and STPS2H100RL specify 1 µA leakage, while SR2010-TP specifies 1 mA. Applications sensitive to leakage current should use the STMicroelectronics parts.

Q: What is the moisture sensitivity level for these parts? A: All three parts have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly.
