HR01302J Equivalent & Substitute Parts

Part Overview

The HR01302J is a 3 kOhm ±5% 1/16W axial through-hole resistor manufactured by KYOCERA AVX using thick film composition. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The part operates across a temperature range of -55°C to 125°C and is non-RoHS compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HR01302J is determined by the following critical parameters:

• Resistance value: 3 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Power rating: Minimum 0.063W (equal or higher acceptable)
• Operating temperature range: Minimum -55°C to 125°C coverage (equal or wider acceptable)
• Number of terminations: 2 (exact match required)

The CFR-12JB-52-3K from YAGEO meets all substitution criteria. While it features carbon film composition instead of thick film and a higher power rating of 0.167W (1/6W), these differences are within acceptable substitution parameters for this resistor category. The substitute part maintains the same resistance, tolerance, axial package, and terminal configuration while providing enhanced thermal performance across an extended operating temperature range of -55°C to 155°C.

Engineering Selection Recommendations

The CFR-12JB-52-3K is the qualified substitute for the HR01302J based on the following factors:

The HR01302J is obsolete, necessitating transition to an active product. The CFR-12JB-52-3K maintains functional equivalence through identical resistance, tolerance, and axial package configuration. The substitute part's higher power rating (0.167W versus 0.063W) provides design margin without affecting circuit performance in applications where the original 1/16W rating was specified.

The CFR-12JB-52-3K achieves ROHS3 compliance, addressing regulatory requirements that may apply to new production. The extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) supports broader application environments. Both parts carry REACH Unaffected and EAR99 classifications.

Frequently Asked Questions (FAQ)

Q: Can the CFR-12JB-52-3K directly replace the HR01302J in existing designs?

A: Yes. Both parts share identical resistance (3 kOhms), tolerance (±5%), and axial package configuration. The substitute's higher power rating and extended temperature range do not create compatibility issues in applications originally designed for the HR01302J.

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

A: Composition differences do not affect substitution eligibility for this resistor category. Both thick film and carbon film compositions meet the specified electrical parameters. The CFR-12JB-52-3K's carbon film construction is standard for active production resistors in this value and power class.

Q: Does the CFR-12JB-52-3K fit the same PCB footprint as the HR01302J?

A: Both parts use axial through-hole packages. Physical dimensions differ slightly (HR01302J: 0.036" square x 0.075" L; CFR-12JB-52-3K: 0.075" diameter x 0.134" L), but both accommodate standard axial component mounting. Verify PCB hole spacing and lead length requirements for your specific application.

Q: Is RoHS compliance required for my application?

A: The HR01302J is RoHS non-compliant, while the CFR-12JB-52-3K is ROHS3 compliant. If your application or market requires RoHS compliance, the CFR-12JB-52-3K is the appropriate selection.

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

A: The HR01302J specifies ±250ppm/°C; the CFR-12JB-52-3K specifies -500/+350ppm/°C. Both values are within acceptable ranges for general-purpose resistor applications. Select based on your circuit's temperature stability requirements.
