HR01103J Equivalent & Substitute Parts

Part Overview

The HR01103J is a 10 kOhms ±5% 1/16W axial through-hole resistor manufactured by KYOCERA AVX using thick film composition. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates across a temperature range of -55°C to 125°C and is suitable for general-purpose resistive applications in electronic circuits requiring axial package configuration.

Substitute Part Grouping Explanation

Substitution of the HR01103J is determined by the following critical parameters:

• Resistance Value: Must be 10 kOhms
• Tolerance: Must be ±5% or tighter
• Package Configuration: Must be axial through-hole
• Number of Terminations: Must be 2
• Power Rating: Must meet or exceed 0.063W (1/16W)
• Operating Temperature Range: Must encompass or exceed -55°C to 125°C

The CFR-12JB-52-10K from YAGEO meets all substitution criteria. While it features carbon film composition instead of thick film and has a higher power rating (0.167W, 1/6W), these differences are compatible with the functional requirements of the HR01103J application space. The substitute maintains identical resistance and tolerance specifications, operates across a wider temperature range (-55°C to 155°C), and retains the axial package configuration.

Parameter Comparison

Engineering Selection Recommendations

The CFR-12JB-52-10K is a direct functional substitute for the HR01103J based on matching resistance, tolerance, and package specifications. The substitute provides enhanced compliance status (ROHS3 compliant versus non-compliant), expanded operating temperature range, and increased power dissipation capability. These characteristics make the CFR-12JB-52-10K suitable for applications previously served by the obsolete HR01103J without requiring circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the CFR-12JB-52-10K replace the HR01103J in existing designs?

A: Yes. Both components share identical resistance (10 kOhms) and tolerance (±5%) specifications, operate within compatible temperature ranges, and use axial through-hole packaging. The substitute's higher power rating (0.167W versus 0.063W) and wider operating temperature range (-55°C to 155°C versus -55°C to 125°C) provide additional design margin.

Q: What is the difference between thick film and carbon film composition?

A: Composition differences affect temperature coefficient stability and frequency response characteristics. The HR01103J uses thick film (±250ppm/°C), while the CFR-12JB-52-10K uses carbon film (-500/+350ppm/°C). For DC and low-frequency applications, both compositions are functionally equivalent at the specified tolerance level.

Q: Are there physical dimension differences between these parts?

A: Yes. The HR01103J measures 0.036" square by 0.075" length (0.91mm x 1.91mm), while the CFR-12JB-52-10K measures 0.075" diameter by 0.134" length (1.90mm x 3.40mm). The substitute is slightly larger but remains compatible with standard axial component PCB layouts.

Q: Does the RoHS compliance difference affect substitution?

A: The CFR-12JB-52-10K is ROHS3 compliant, whereas the HR01103J is non-compliant. For new designs or applications subject to RoHS regulations, the substitute provides regulatory compliance advantage. For legacy systems, both parts function identically from an electrical standpoint.
