HR01303J Equivalent & Substitute Parts

Part Overview

The HR01303J is a 30 kOhm ±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 HR01303J is based on the following critical parameters that must remain constant or compatible:

• Resistance value: 30 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Number of terminations: 2 (exact match required)

The substitute part CFR-12JB-52-30K meets these core electrical and mechanical requirements. While the substitute features a higher power rating (0.167W vs. 0.063W) and different composition (carbon film vs. thick film), these parameters are compatible with the HR01303J's functional role. The substitute's extended operating temperature range (-55°C to 155°C) and active product status provide additional advantages for long-term availability.

Parameter Comparison

Engineering Selection Recommendations

The CFR-12JB-52-30K is a direct functional substitute for the HR01303J based on matching resistance, tolerance, and axial package configuration. The substitute's higher power rating provides additional thermal margin in circuit applications. The CFR-12JB-52-30K is an active product with ROHS3 compliance, ensuring long-term availability and regulatory alignment compared to the obsolete HR01303J.

Frequently Asked Questions (FAQ)

Q: Can the CFR-12JB-52-30K replace the HR01303J in all applications? A: Yes, the CFR-12JB-52-30K meets the critical electrical parameters (30 kOhms ±5%) and package requirements (axial, 2 terminations) for direct substitution. The higher power rating and extended temperature range are compatible with HR01303J applications.

Q: What is the difference between thick film and carbon film composition? A: Both compositions are suitable for general-purpose resistor applications. Carbon film resistors typically offer lower cost and are widely available. Thick film resistors may provide different noise characteristics. For the 30 kOhm ±5% specification, either composition is functionally equivalent.

Q: Are the physical dimensions compatible? A: Both parts use axial through-hole packaging. The CFR-12JB-52-30K has slightly larger dimensions (0.075" Dia x 0.134" L vs. 0.036" Square x 0.075" L), but both fit standard through-hole PCB layouts designed for axial resistors.

Q: Does the temperature coefficient difference affect substitution? A: The HR01303J has ±250ppm/°C while the CFR-12JB-52-30K has -500/+350ppm/°C. Both coefficients are within acceptable ranges for general-purpose resistor applications. The substitute's extended operating temperature range (-55°C to 155°C) provides additional margin.

Q: Is RoHS compliance a concern for substitution? A: The CFR-12JB-52-30K is ROHS3 compliant, while the HR01303J is not. For new designs and regulated applications, the ROHS3-compliant substitute is preferred. For legacy system maintenance, either part may be acceptable depending on application requirements.
