RC1KB10R0 Equivalent & Substitute Parts

Part Overview

The RC1KB10R0 is a 10 Ohm, ±10% tolerance, 1W through-hole axial resistor 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 currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance, repair, and legacy design support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC1KB10R0 is determined by the following critical parameters:

• Resistance Value: Must be 10 Ohms
• Power Rating: Must be 1W minimum
• Package Type: Must be Axial configuration for mechanical and electrical compatibility
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Regulatory Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The ASRM1JA10R0 qualifies as a direct substitute based on matching resistance, power rating, axial package, and regulatory compliance. While the substitute features improved tolerance (±5% versus ±10%) and extended upper operating temperature (155°C versus 125°C), these represent performance enhancements rather than deviations from the original specification.

Parameter Comparison

Engineering Selection Recommendations

The ASRM1JA10R0 is suitable for direct substitution of the RC1KB10R0 in applications requiring a 10 Ohm, 1W axial resistor. The substitute maintains full regulatory compliance with ROHS3 and REACH requirements. The active product status of the ASRM1JA10R0 ensures ongoing availability and supply chain continuity, addressing the obsolescence of the original RC1KB10R0.

The transition from carbon composition to metal film construction in the substitute provides improved tolerance performance (±5% versus ±10%) and extended operating temperature capability (155°C versus 125°C upper limit). These characteristics are compatible with the original design parameters and do not introduce incompatibility in standard circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the ASRM1JA10R0 be used as a direct replacement for the RC1KB10R0?

A: Yes. Both components share identical resistance value (10 Ohms), power rating (1W), and axial package configuration. The substitute meets or exceeds the operating temperature range and maintains equivalent regulatory compliance.

Q: What is the primary difference between these two resistors?

A: The RC1KB10R0 uses carbon composition construction with ±10% tolerance, while the ASRM1JA10R0 uses metal film construction with ±5% tolerance. The metal film substitute offers tighter tolerance and extended temperature range (-55°C to 155°C versus -55°C to 125°C).

Q: Are there any compatibility concerns with the axial package?

A: No. Both components use identical axial package configuration with equivalent mechanical dimensions suitable for through-hole mounting on standard PCB layouts.

Q: Does the substitute maintain regulatory compliance?

A: Yes. The ASRM1JA10R0 is ROHS3 compliant and REACH unaffected, matching the compliance status of the original RC1KB10R0.

Q: Why is the RC1KB10R0 listed as obsolete?

A: The RC1KB10R0 has been discontinued by the manufacturer. The ASRM1JA10R0 represents the active equivalent from the same manufacturer for ongoing procurement and design applications.
