HR01331J Equivalent & Substitute Parts

Part Overview

The HR01331J is a 330 Ohm ±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 not RoHS compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HR01331J is based on the following critical parameters:

Resistance value and tolerance must remain identical at 330 Ohms ±5%. The axial package configuration is mandatory for mechanical and electrical compatibility with existing PCB layouts. The two-termination through-hole design is non-negotiable for board assembly compatibility.

The substitute part CFR-12JB-52-330R by YAGEO meets these core requirements. While the substitute features a higher power rating (0.167W vs. 0.063W) and different composition (carbon film vs. thick film), these parameters represent functional improvements that do not compromise circuit performance. The substitute's operating temperature range of -55°C to 155°C exceeds the original specification, providing extended thermal capability.

Parameter Comparison

Engineering Selection Recommendations

The CFR-12JB-52-330R is the direct substitute for the obsolete HR01331J. Selection is justified by identical electrical specifications (330 Ohms ±5%) and compatible axial package configuration. The substitute's higher power dissipation capability (0.167W) and extended operating temperature range (up to 155°C) provide design margin without introducing incompatibility.

The YAGEO CFR-12JB-52-330R carries active product status with ROHS3 compliance, addressing regulatory requirements that the original part does not meet. This substitution is suitable for new designs and replacement applications where component availability is a constraint.

Frequently Asked Questions (FAQ)

Q: Can the CFR-12JB-52-330R replace the HR01331J in existing circuits?

A: Yes. Both components share identical resistance (330 Ohms) and tolerance (±5%), with matching axial package configuration and two-termination design. The substitute's higher power rating and extended temperature range do not create compatibility issues.

Q: What is the difference in physical dimensions between these parts?

A: The HR01331J measures 0.036" square by 0.075" length (0.91mm x 1.91mm). The CFR-12JB-52-330R measures 0.075" diameter by 0.134" length (1.90mm x 3.40mm). Both fit standard axial component footprints, though board layout verification is recommended for space-constrained applications.

Q: Does the composition difference (thick film vs. carbon film) affect performance?

A: Composition differences do not affect the core electrical parameters that determine substitutability. Both compositions deliver the specified 330 Ohm resistance and ±5% tolerance. The carbon film composition of the substitute is a mature, widely-used technology.

Q: Is the CFR-12JB-52-330R RoHS compliant?

A: Yes, the CFR-12JB-52-330R is ROHS3 compliant, whereas the original HR01331J is not RoHS compliant. This makes the substitute suitable for applications with RoHS regulatory requirements.

Q: What is the temperature coefficient difference?

A: The HR01331J has a temperature coefficient of ±250ppm/°C. The CFR-12JB-52-330R has an asymmetrical coefficient of -500/+350ppm/°C. Both values are within acceptable ranges for general-purpose resistor applications.
