HR01224J Equivalent & Substitute Parts

Part Overview

The HR01224J is a 220 kOhms ±5% 1/16W axial through-hole resistor manufactured by Kyocera AVX using thick film composition. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The primary driver for substitution is product discontinuation combined with the need for functionally compatible alternatives that meet the same electrical and mechanical requirements.

Substitute Part Grouping Explanation

Substitution of the HR01224J is based on the following critical parameters that must remain constant or compatible:

• Resistance Value: 220 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Package Configuration: Axial through-hole (mechanical and electrical compatibility)
• Number of Terminations: 2 (pin count match)
• Operating Temperature Range: Minimum -55°C ~ 125°C (substitute must meet or exceed this range)
• Power Rating: Minimum 0.063W (substitute may exceed this specification)

The CFR-12JB-52-220K meets all substitution criteria. While it uses carbon film composition instead of thick film and has a higher power rating (0.167W vs 0.063W), these differences are compatible with the application requirements. The higher power rating provides additional thermal margin, and carbon film composition is functionally equivalent for this resistance value and tolerance class in axial package form.

Parameter Comparison

Engineering Selection Recommendations

The CFR-12JB-52-220K is the qualified substitute for the HR01224J based on the following engineering criteria:

Electrical Compatibility: Both parts provide identical resistance (220 kOhms) and tolerance (±5%), ensuring direct functional equivalence in circuit operation.

Mechanical Compatibility: Both parts use axial through-hole packaging with two terminations, allowing direct board-level substitution without layout modifications.

Thermal Performance: The CFR-12JB-52-220K operates across -55°C ~ 155°C, which exceeds the HR01224J operating range of -55°C ~ 125°C. This extended range provides additional design margin.

Power Dissipation: The substitute's 0.167W rating exceeds the original 0.063W specification, providing thermal headroom in the application.

Product Availability: The HR01224J is obsolete with no ongoing production. The CFR-12JB-52-220K is active with 5522 units in stock, ensuring supply continuity.

Compliance Status: The CFR-12JB-52-220K is RoHS3 compliant, whereas the HR01224J is RoHS non-compliant. This difference should be evaluated against your product's regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the CFR-12JB-52-220K be used as a direct replacement for the HR01224J?

A: Yes. Both parts have identical resistance (220 kOhms), tolerance (±5%), and axial package configuration with two terminations. The substitute can be installed in the same board position without modification.

Q: Why does the substitute have a higher power rating?

A: The CFR-12JB-52-220K is rated at 0.167W compared to the HR01224J at 0.063W. A higher power rating is compatible with applications designed for lower power dissipation, as it provides additional thermal margin without affecting electrical performance.

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

A: Both compositions are suitable for general-purpose resistor applications at this resistance value and tolerance. The composition difference does not affect functional compatibility in standard circuit applications.

Q: Does the substitute's extended operating temperature range affect compatibility?

A: No. The CFR-12JB-52-220K operates from -55°C ~ 155°C, which encompasses the HR01224J range of -55°C ~ 125°C. The extended range provides additional design margin without introducing compatibility issues.

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

A: The HR01224J has a temperature coefficient of ±250ppm/°C, while the CFR-12JB-52-220K has 0 / -700ppm/°C. For applications operating within the -55°C ~ 125°C range, both coefficients produce acceptable resistance drift. The substitute's coefficient should be evaluated if your application requires tight resistance stability across the full temperature range.

Q: Are there RoHS compliance implications?

A: The HR01224J is RoHS non-compliant, while the CFR-12JB-52-220K is RoHS3 compliant. If your product requires RoHS compliance, the substitute provides this benefit. If your existing design is RoHS non-compliant, this difference does not affect substitution feasibility.

Q: Can multiple substitute parts be used interchangeably?

A: Based on the provided data, CFR-12JB-52-220K is the qualified substitute. The CFR16J220K is listed as a secondary substitute for the CFR-12JB-52-220K but is not directly evaluated against the HR01224J in this reference.
