HR01103JR Equivalent & Substitute Parts

Part Overview

The HR01103JR 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 RoHS non-compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HR01103JR is determined by the following critical parameters:

• Resistance Value: Must be 10 kOhms
• Tolerance: Must be ±5%
• Package Type: Must be Axial through-hole configuration
• 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-12JR-52-10K from YAGEO meets all substitution criteria. While it uses 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 HR01103JR. The substitute maintains identical resistance, tolerance, package configuration, and termination count while providing an active product status with improved temperature range coverage (-55°C to 155°C).

Parameter Comparison

Engineering Selection Recommendations

The CFR-12JR-52-10K is the qualified substitute for the HR01103JR based on the following factors:

• Functional Equivalence: Identical resistance value, tolerance, and axial package configuration ensure direct functional replacement in circuit applications.
• Product Availability: The substitute is active in production with 18,826 pieces in stock, compared to the obsolete status of the original part.
• Compliance Advantage: The CFR-12JR-52-10K is ROHS3 compliant, addressing regulatory requirements that the original HR01103JR does not meet.
• Enhanced Specifications: The higher power rating (0.167W vs. 0.063W) and extended operating temperature range (-55°C to 155°C vs. -55°C to 125°C) provide operational margin without compromising circuit performance.
• Packaging Format: Available in Cut Tape (CT) packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the CFR-12JR-52-10K directly replace the HR01103JR in existing designs?

A: Yes. Both components share identical resistance (10 kOhms), tolerance (±5%), and axial package configuration with two terminations. The substitute's higher power rating and extended temperature range are compatible with applications designed for the original part.

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

A: Composition differences do not affect substitution validity when resistance, tolerance, and power ratings are equivalent. The CFR-12JR-52-10K's carbon film construction is functionally compatible with circuits designed for the HR01103JR's thick film resistor.

Q: Does the higher power rating of the substitute affect circuit performance?

A: No. A higher power rating (0.167W vs. 0.063W) indicates the substitute can safely dissipate more power without degradation. This provides additional operational margin and does not negatively impact circuit function.

Q: Is the CFR-12JR-52-10K suitable for applications requiring RoHS compliance?

A: Yes. The CFR-12JR-52-10K is ROHS3 compliant, making it suitable for applications with RoHS regulatory requirements. The original HR01103JR is RoHS non-compliant.

Q: Are there any dimensional differences between the two parts?

A: Yes. The HR01103JR measures 0.036" square x 0.075" L (0.91mm x 1.91mm), while the CFR-12JR-52-10K measures 0.075" diameter x 0.134" L (1.90mm x 3.40mm). Both are axial through-hole components; verify PCB layout compatibility before implementation.

Q: What is the temperature coefficient difference, and does it matter?

A: The HR01103JR has ±250ppm/°C, while the CFR-12JR-52-10K has -500/+350ppm/°C. For most general-purpose applications, this difference is not critical. Verify temperature stability requirements for precision circuits before selection.
