Engineering Selection Recommendations

RC2010FK-075K1L (YAGEO) - Enhanced Tolerance Variant: This substitute provides improved tolerance specification (±1% versus ±5%) with increased power rating (0.75W versus 0.667W). Selection is appropriate for applications requiring tighter resistance value control while maintaining full thermal and mechanical compatibility. All compliance certifications (RoHS3, REACH Unaffected, EAR99) are equivalent to the original part.

RC2010JK-075K1L (YAGEO) - Power-Rated Variant: This substitute maintains the original ±5% tolerance specification while providing increased power rating (0.75W versus 0.667W). Selection is appropriate for applications where the original power rating is marginal or where design margin improvement is required. Mechanical footprint and thermal characteristics remain identical to the original part.

Both substitutes are Active status components with full inventory availability and equivalent compliance documentation. Selection between the two YAGEO alternatives depends on whether tolerance improvement (RC2010FK-075K1L) or power margin (RC2010JK-075K1L) is the primary design requirement.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-075K1L and RC2010JK-075K1L be used interchangeably with RC5025J512CS?

A: Both YAGEO parts are direct substitutes for the Samsung RC5025J512CS. They share identical resistance value (5.1 kOhms), package (2010/5025 Metric), composition (Thick Film), thermal characteristics (±100ppm/°C, -55°C to 155°C), and compliance status (RoHS3, MSL 1). The primary differences are tolerance and power rating, which represent upgrades rather than limitations.

Q: What is the difference between RC2010FK-075K1L and RC2010JK-075K1L?

A: RC2010FK-075K1L offers ±1% tolerance with 0.75W power rating. RC2010JK-075K1L offers ±5% tolerance with 0.75W power rating. Both have identical mechanical dimensions and thermal performance. Selection depends on whether tighter tolerance control is required for the application.

Q: Are the physical dimensions identical between all three parts?

A: Yes. All three parts use the 2010 (5025 Metric) package with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated height is 0.026" (0.66mm for Samsung, 0.65mm for YAGEO variants), which is within acceptable PCB assembly tolerances.

Q: Do the substitute parts have the same moisture sensitivity level?

A: Yes. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What is the packaging difference between the original and substitute parts?

A: The original RC5025J512CS is supplied in standard packaging. The YAGEO substitutes (RC2010FK-075K1L and RC2010JK-075K1L) are supplied in Tape & Reel (TR) format, which is standard for high-volume production environments and offers no functional difference.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC5025J512CS, RC2010FK-075K1L, and RC2010JK-075K1L are all ROHS3 Compliant with REACH Unaffected status and EAR99 ECCN classification.
