Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC12JB82K0 is determined by the following critical parameters:

• Resistance Value: Must be 82 kOhms
• Tolerance: Must be ±5%
• Package Configuration: Must be axial through-hole
• Electrical Characteristics: Must support pulse withstanding capability
• Compliance: Must maintain ROHS3 compliance

The ASRM1JA82K0 qualifies as a substitute based on matching resistance, tolerance, package type, and compliance requirements. While the substitute features a higher power rating (1W versus 0.5W) and different composition (metal film versus carbon composition), these parameters represent functional improvements that do not compromise compatibility in applications designed for the original component.

Parameter Comparison

Engineering Selection Recommendations

The ASRM1JA82K0 is the qualified substitute for the obsolete RC12JB82K0. Both components are manufactured by Stackpole Electronics Inc and maintain ROHS3 compliance. The substitute is currently in active production status with confirmed inventory availability (1121 pcs), whereas the original part is obsolete with limited stock (764 pcs).

The substitute provides enhanced specifications including doubled power rating (1W versus 0.5W), extended maximum operating temperature (155°C versus 125°C), and metal film construction with flame retardant coating. These characteristics ensure functional compatibility while offering improved performance margins for circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the ASRM1JA82K0 directly replace the RC12JB82K0 in existing designs?

A: Yes. Both components share identical resistance value (82 kOhms), tolerance (±5%), and axial package configuration. The substitute's higher power rating and extended temperature range provide functional compatibility without circuit modification.

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

A: The RC12JB82K0 measures 0.142" diameter × 0.374" length (3.60mm × 9.50mm). The ASRM1JA82K0 measures 0.157" diameter × 0.433" length (4.00mm × 11.00mm). Both are axial through-hole components with 2 terminations. PCB layout verification is required to confirm mechanical fit.

Q: Are there compliance or certification differences?

A: Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No compliance barriers exist for substitution.

Q: Why does the substitute use metal film composition instead of carbon composition?

A: Metal film resistors provide superior stability, lower temperature coefficient (0/-1800ppm/°C), and improved pulse withstanding performance compared to carbon composition. This represents a technical upgrade suitable for the same application space.

Q: What is the inventory status for procurement decisions?

A: The RC12JB82K0 (obsolete) has 764 pcs available. The ASRM1JA82K0 (active) has 1121 pcs available with ongoing production support, making it the preferred choice for new procurement and long-term supply chain continuity.
