Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC12JB10K0 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 10 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 0.5W / 1/2W (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Termination Count: 2 (exact match required)
• Operating Temperature Range: Minimum -55°C to 125°C coverage
• Regulatory Compliance: ROHS3 Compliant

The ASRM12JB10K0 qualifies as a manufacturer-recommended substitute. While it differs in composition (metal film vs. carbon composition) and features enhanced temperature coefficient performance (-1800ppm/°C) with extended upper operating temperature (155°C), it maintains electrical equivalence across all critical substitution parameters.

Engineering Selection Recommendations

The ASRM12JB10K0 is the manufacturer-recommended substitute for the obsolete RC12JB10K0. Both parts maintain ROHS3 compliance and are manufactured by Stackpole Electronics Inc, ensuring supply chain continuity and regulatory alignment.

The substitute offers operational advantages including extended temperature range coverage (155°C vs. 125°C maximum) and specified temperature coefficient performance, beneficial for applications requiring enhanced thermal stability. The metal film composition with flame retardant coating provides improved safety characteristics compared to the original carbon composition design.

Physical dimensions differ slightly (0.118" Dia x 0.354" L vs. 0.142" Dia x 0.374" L), requiring verification of mechanical fit within existing circuit board layouts and component mounting constraints.

Frequently Asked Questions (FAQ)

Q: Can the ASRM12JB10K0 be used as a direct replacement for RC12JB10K0?

A: Yes. Both parts share identical resistance (10 kOhms), tolerance (±5%), power rating (0.5W), and axial package configuration. The ASRM12JB10K0 is the manufacturer-recommended substitute for the obsolete RC12JB10K0.

Q: What are the physical dimension differences between these parts?

A: The RC12JB10K0 measures 0.142" Dia x 0.374" L (3.60mm x 9.50mm). The ASRM12JB10K0 measures 0.118" Dia x 0.354" L (3.00mm x 9.00mm). Verify mechanical fit within your specific circuit board layout before implementation.

Q: Does the composition change from carbon to metal film affect circuit performance?

A: Both compositions meet the specified electrical parameters (10 kOhms ±5%, 0.5W). The metal film composition of the substitute provides improved temperature coefficient stability (-1800ppm/°C) and extended operating temperature range (-55°C to 155°C vs. -55°C to 125°C).

Q: Are both parts RoHS compliant?

A: Yes. Both RC12JB10K0 and ASRM12JB10K0 are ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the product status difference between these parts?

A: The RC12JB10K0 is classified as obsolete, while the ASRM12JB10K0 is active. The active status of the substitute ensures ongoing availability and manufacturing support.
