Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0100JR-079K1L is determined by the following critical parameters:

• Resistance Value: Must be 9.1 kOhms
• Package Format: Must be 01005 (0402 Metric) with identical footprint dimensions (0.40mm × 0.20mm)
• Power Rating: Must support minimum 0.03W (1/32W) dissipation
• Composition: Thick film construction
• Temperature Coefficient: ±200ppm/°C
• Operating Temperature Range: -55°C to 125°C minimum
• Moisture Resistance: Required feature
• Compliance: ROHS3 and REACH Unaffected status

The RC0100FR-079K1L qualifies as a direct substitute based on matching all mechanical and electrical parameters. The primary distinction is tolerance specification: the substitute offers ±1% tolerance versus the original ±5%, representing an upgrade in precision while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RC0100JR-079K1L and RC0100FR-079K1L are Active status components manufactured by YAGEO with identical ROHS3 and REACH compliance certifications. Selection between these parts depends on circuit tolerance requirements:

The RC0100JR-079K1L (±5% tolerance) is appropriate for applications where standard tolerance specifications are acceptable and cost optimization is prioritized.

The RC0100FR-079K1L (±1% tolerance) is suitable for precision circuits requiring tighter resistance value control. This substitute provides enhanced accuracy while maintaining full mechanical and thermal compatibility, identical package footprint, and equivalent compliance certifications.

Both parts are qualified for the same operating environment (-55°C to 125°C) and moisture conditions (MSL 1). PCB layout and assembly processes require no modification when substituting between these parts.
