Substitute Part Grouping Explanation

Substitution of the SM2615FT10R2 is determined by the following critical parameters:

• Resistance Value: Must be 10.2 Ohms
• Package / Case: Must be 2615 J-Lead to ensure mechanical and electrical compatibility
• Power Rating: Must be 1W minimum
• Composition: Wirewound construction required for pulse withstanding and current sensing applications
• Temperature Coefficient: ±20ppm/°C maintains thermal stability
• Operating Temperature Range: Must support -55°C ~ 275°C
• RoHS Compliance: ROHS3 Compliant status required for regulatory alignment

The substitute part S2-10R2D8 from Riedon meets all mandatory substitution criteria while offering improved tolerance (±0.5% versus ±1%) and enhanced feature set including flame proof and safety certifications.

Frequently Asked Questions (FAQ)

Q: Can the S2-10R2D8 be used as a direct replacement for the SM2615FT10R2?

A: Yes. Both components share identical resistance values (10.2 Ohms), power ratings (1W), package configurations (2615 J-Lead), temperature coefficients (±20ppm/°C), and operating temperature ranges (-55°C ~ 275°C). The substitute part meets all electrical and mechanical requirements for direct substitution.

Q: What are the dimensional differences between these parts?

A: The SM2615FT10R2 measures 0.280" L x 0.150" W (7.10mm x 3.80mm) with a maximum seated height of 0.155" (3.94mm). The S2-10R2D8 measures 0.260" L x 0.154" W (6.60mm x 3.90mm) with a maximum seated height of 0.142" (3.60mm). Both fit the 2615 J-Lead package specification and are compatible with existing PCB layouts designed for this package type.

Q: Does the improved tolerance of the S2-10R2D8 affect circuit performance?

A: The S2-10R2D8 tolerance of ±0.5% is tighter than the SM2615FT10R2 tolerance of ±1%. This provides improved precision for current sensing and measurement applications. Circuits designed for ±1% tolerance will operate within specification with the ±0.5% substitute part.

Q: Are both parts RoHS compliant?

A: Yes. Both the SM2615FT10R2 and S2-10R2D8 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting current regulatory requirements for electronic component manufacturing and assembly.

Q: What is the packaging format for the S2-10R2D8?

A: The S2-10R2D8 is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The SM2615FT10R2 packaging format was not specified in the available data.
