RC1KB22K0 Equivalent & Substitute Parts

Part Overview

The RC1KB22K0 is a 22 kOhms ±10% 1W through hole resistor in axial package manufactured by Stackpole Electronics Inc. This carbon composition resistor features non-inductive and pulse withstanding characteristics, with an operating temperature range of -55°C to 125°C. The product is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC1KB22K0 is based on the following critical parameters:

• Resistance value: 22 kOhms (exact match required)
• Power rating: 1W (minimum requirement)
• Package configuration: Axial through hole (mechanical compatibility)
• Operating temperature range: Must encompass or exceed -55°C ~ 125°C
• Regulatory compliance: ROHS3 compliance maintained

The ASRM1JA22K0 qualifies as a direct substitute based on matching resistance, power rating, and axial package configuration. While the substitute features improved tolerance (±5% versus ±10%) and extended operating temperature range (-55°C ~ 155°C), these represent enhancements rather than deviations from the original specification.

Parameter Comparison

Engineering Selection Recommendations

The ASRM1JA22K0 is suitable for direct substitution of the RC1KB22K0 in applications requiring a 22 kOhms 1W axial resistor. Both components maintain ROHS3 compliance and are manufactured by the same supplier. The substitute part is currently in active production status, ensuring long-term availability compared to the obsolete RC1KB22K0.

The transition from carbon composition to metal film construction in the substitute provides improved tolerance performance (±5% versus ±10%) and extended temperature capability (-55°C ~ 155°C versus -55°C ~ 125°C). These characteristics are compatible with the original specification parameters.

Frequently Asked Questions (FAQ)

Q: Can the ASRM1JA22K0 be used as a direct replacement for the RC1KB22K0?

A: Yes. Both components share identical resistance value (22 kOhms), power rating (1W), and axial package configuration. The substitute meets or exceeds all specified operating parameters.

Q: What is the difference in composition between these parts?

A: The RC1KB22K0 uses carbon composition construction, while the ASRM1JA22K0 uses metal film construction. Both are suitable for the specified 1W power rating and operating temperature range.

Q: Does the improved tolerance of the substitute affect circuit compatibility?

A: The ASRM1JA22K0 tolerance of ±5% is tighter than the original ±10% specification. This represents improved performance and does not create compatibility issues in applications designed for the RC1KB22K0.

Q: Are there packaging differences between these components?

A: Both components use axial through hole packaging. The ASRM1JA22K0 is supplied in cut tape (CT) packaging, while the RC1KB22K0 was supplied in standard packaging. Physical dimensions are similar (4.00mm x 11.00mm versus 5.70mm x 14.30mm), with both suitable for standard PCB through hole assembly.

Q: What is the temperature range difference?

A: The RC1KB22K0 operates from -55°C to 125°C, while the ASRM1JA22K0 extends to 155°C maximum. Applications within the original temperature range are fully supported by the substitute.
