HR01102G-LF Equivalent & Substitute Parts

Part Overview

The HR01102G-LF is a 1 kOhm ±2% 1/16W axial through-hole resistor manufactured by KYOCERA AVX using thick film composition. This component is classified as obsolete, making substitute parts necessary for ongoing production and maintenance applications. The part operates across a temperature range of -55°C to 125°C and is not RoHS compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HR01102G-LF is based on the following critical parameters:

• Resistance Value: 1 kOhms (exact match required)
• Package Type: Axial through-hole configuration (mechanical compatibility)
• Termination Count: 2 terminations (functional requirement)
• Operating Temperature Range: Minimum -55°C to 125°C coverage
• Tolerance and Power Rating: Allowable variance within application requirements

The CFR-12JB-52-1K from YAGEO meets the core functional requirements of resistance value, package type, and termination configuration. While tolerance and power rating differ from the original specification, the substitute part operates within the same temperature envelope and maintains axial package compatibility for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

The CFR-12JB-52-1K is an active production component with ROHS3 compliance, addressing the obsolescence of the HR01102G-LF. The substitute part maintains identical resistance value and axial package configuration, enabling direct mechanical and electrical replacement in through-hole applications.

Key differences include tolerance specification (±5% versus ±2%), power rating (0.167W versus 0.063W), and composition (carbon film versus thick film). The substitute part provides higher power dissipation capability and extended operating temperature range to 155°C. These characteristics make the CFR-12JB-52-1K suitable for applications where the original HR01102G-LF specifications can accommodate the relaxed tolerance and alternative film composition.

Frequently Asked Questions (FAQ)

Q: Can the CFR-12JB-52-1K directly replace the HR01102G-LF in existing designs?

A: Yes, for applications where ±5% tolerance is acceptable. Both components share identical 1 kOhm resistance, axial package type, and two-termination configuration. Verify that circuit design tolerances can accommodate the ±5% specification of the substitute part.

Q: What are the physical dimension differences between these parts?

A: The HR01102G-LF measures 0.036" square by 0.075" length (0.91mm x 1.91mm). The CFR-12JB-52-1K measures 0.075" diameter by 0.134" length (1.90mm x 3.40mm). Both are axial packages suitable for standard through-hole PCB layouts, though the substitute part is physically larger.

Q: Does the higher power rating of the CFR-12JB-52-1K affect circuit performance?

A: No. The 0.167W rating of the substitute part exceeds the 0.063W requirement of the original design. Higher power rating provides additional thermal margin and does not alter electrical behavior in the circuit.

Q: Are there compliance differences between the original and substitute part?

A: Yes. The HR01102G-LF is RoHS non-compliant, while the CFR-12JB-52-1K is ROHS3 compliant. Both parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: What is the significance of the different temperature coefficients?

A: The HR01102G-LF has a symmetric temperature coefficient of ±250ppm/°C. The CFR-12JB-52-1K has an asymmetric coefficient of -500/+350ppm/°C. For applications operating across the full temperature range, verify that circuit performance remains within specification with the substitute part's temperature coefficient characteristics.
