RC14KB10K0 Equivalent & Substitute Parts

Part Overview

The RC14KB10K0 is a 10 kOhms ±10% 0.25W axial through-hole resistor manufactured by Stackpole Electronics Inc. This carbon composition resistor features non-inductive and pulse withstanding characteristics, designed for applications requiring robust performance across the -55°C to 125°C operating temperature range. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and legacy system support.

Substitute Part Grouping Explanation

The ASR14JT10K0 qualifies as a direct substitute for the RC14KB10K0 based on the following critical parameters:

• Resistance Value: Both parts are 10 kOhms
• Power Rating: Both are rated at 0.25W (1/4W)
• Package Type: Both use axial through-hole configuration
• Termination Count: Both have 2 terminations
• Compliance: Both are ROHS3 compliant and EAR99 classified

The ASR14JT10K0 represents an upgrade path, offering improved tolerance (±5% versus ±10%), metal film construction with flame retardant coating, and an extended operating temperature range (-55°C to 155°C versus -55°C to 125°C). The physical dimensions are comparable, with the substitute being marginally smaller (0.091" Dia x 0.236" L versus 0.094" Dia x 0.248" L).

Parameter Comparison

Engineering Selection Recommendations

The ASR14JT10K0 is the manufacturer-recommended substitute for the obsolete RC14KB10K0. Both parts maintain identical resistance values, power ratings, and axial package configurations, ensuring direct functional compatibility in circuit applications. The substitute offers superior tolerance specifications (±5% versus ±10%), which may improve circuit accuracy in precision applications. Both parts maintain ROHS3 compliance and are classified under the same ECCN and HTSUS codes, supporting regulatory and procurement continuity. The ASR14JT10K0's active product status ensures ongoing availability and supply chain reliability, whereas the RC14KB10K0's obsolete status limits future sourcing options.

Frequently Asked Questions (FAQ)

Q: Can the ASR14JT10K0 directly replace the RC14KB10K0 in existing designs?

A: Yes. Both parts share identical resistance values (10 kOhms), power ratings (0.25W), and axial package configurations. The physical dimensions are comparable, and both are ROHS3 compliant. The substitute is a direct functional replacement.

Q: What are the key differences between these two resistors?

A: The primary differences are composition (carbon composition versus metal film), tolerance (±10% versus ±5%), operating temperature range (-55°C to 125°C versus -55°C to 155°C), and product status (obsolete versus active). The ASR14JT10K0 offers improved tolerance and extended temperature capability.

Q: Will the tighter tolerance of the ASR14JT10K0 affect circuit performance?

A: The ±5% tolerance of the ASR14JT10K0 is superior to the ±10% tolerance of the RC14KB10K0. In applications where the original ±10% tolerance was acceptable, the tighter tolerance will not negatively impact performance and may improve circuit accuracy.

Q: Are there any physical installation considerations when substituting these parts?

A: Both parts use axial through-hole packages with comparable dimensions. The ASR14JT10K0 is marginally smaller (0.091" Dia x 0.236" L versus 0.094" Dia x 0.248" L), which presents no installation constraints in standard PCB layouts designed for the RC14KB10K0.

Q: What is the compliance status of both parts?

A: Both the RC14KB10K0 and ASR14JT10K0 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. They share identical HTSUS classifications, supporting regulatory and procurement continuity.
