HR01115J Equivalent & Substitute Parts

Part Overview

The HR01115J is a 1.1 MOhms ±5% 1/16W axial through-hole resistor manufactured by KYOCERA AVX using thick film composition. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. 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 HR01115J is determined by the following critical parameters:

Electrical Compatibility:

• Resistance value: 1.1 MOhms (exact match required)
• Tolerance: ±5% (equivalent tolerance acceptable)
• Power rating: Substitute must meet or exceed 0.063W minimum

Mechanical Compatibility:

• Package: Axial through-hole configuration (required for PCB layout compatibility)
• Terminations: 2-pin axial lead structure

Environmental Compatibility:

• Operating temperature range must encompass or exceed -55°C to 125°C
• Moisture sensitivity and RoHS compliance are secondary considerations for functional substitution

The CFR-12JB-52-1M1 (YAGEO) satisfies all primary substitution criteria with identical resistance and tolerance values, axial package configuration, and superior power rating (0.167W vs. 0.063W), providing design margin.

Parameter Comparison

Engineering Selection Recommendations

The CFR-12JB-52-1M1 is the designated substitute for the obsolete HR01115J based on the following factors:

Functional Equivalence: Both components provide 1.1 MOhms resistance at ±5% tolerance with identical axial through-hole package configuration, ensuring direct PCB layout compatibility without redesign.

Product Status: The CFR-12JB-52-1M1 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete HR01115J.

Compliance Advantage: The substitute achieves ROHS3 compliance, addressing regulatory requirements that the original part does not meet.

Performance Margin: The CFR-12JB-52-1M1 provides 2.65× higher power rating (0.167W vs. 0.063W) and extended operating temperature range (-55°C to 155°C vs. -55°C to 125°C), offering design robustness.

Composition Difference: The substitute uses carbon film construction versus the original thick film composition. This difference does not affect substitution validity for standard circuit applications where the specified electrical parameters are met.

Frequently Asked Questions (FAQ)

Q: Can the CFR-12JB-52-1M1 directly replace the HR01115J without circuit modification?

A: Yes. Both components share identical resistance (1.1 MOhms), tolerance (±5%), and axial package configuration. Direct PCB substitution is possible without circuit redesign.

Q: What is the significance of the power rating difference (0.063W vs. 0.167W)?

A: The substitute's higher power rating provides additional thermal margin. In applications where the original 0.063W rating was adequate, the 0.167W rating ensures safe operation with design headroom.

Q: Does the composition change from thick film to carbon film affect performance?

A: Composition differences do not affect substitution validity when electrical parameters (resistance, tolerance, power rating) and package configuration are equivalent. Both compositions meet the specified electrical requirements.

Q: Why is the HR01115J classified as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The CFR-12JB-52-1M1 provides functional equivalence with active production status, ensuring continued availability.

Q: Are there any compliance considerations for this substitution?

A: The substitute achieves ROHS3 compliance, whereas the original is non-compliant. For applications subject to RoHS regulations, the CFR-12JB-52-1M1 is the appropriate choice.

Q: What is the physical size difference between these components?

A: HR01115J: 0.036" square × 0.075" length. CFR-12JB-52-1M1: 0.075" diameter × 0.134" length. Both fit standard axial through-hole PCB layouts; verify clearance in space-constrained designs.
