Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC1KB82K0 is determined by the following critical parameters:

• Resistance Value: 82 kOhms (exact match required)
• Power Rating: 1W (exact match required)
• Package Configuration: Axial through hole (exact match required)
• Tolerance: ±10% or tighter (±5% acceptable as improvement)
• Operating Temperature Range: Minimum -55°C to 125°C coverage
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The substitute part ASRM1JA82K0 meets all critical substitution criteria while offering improved tolerance specification and extended upper operating temperature capability.

Parameter Comparison

Engineering Selection Recommendations

The ASRM1JA82K0 is a direct substitute for the RC1KB82K0 based on matching resistance value, power rating, and axial package configuration. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The substitute part offers the following advantages: tighter tolerance specification (±5% versus ±10%), extended operating temperature range (-55°C to 155°C versus -55°C to 125°C), and active product status ensuring long-term availability. The ASRM1JA82K0 utilizes metal film composition with flame retardant coating, compared to the carbon composition construction of the original part.

Physical dimensions differ between the two components. The substitute is smaller in both diameter and length, which may require PCB layout verification for space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can ASRM1JA82K0 directly replace RC1KB82K0 in existing designs?

A: Yes, the ASRM1JA82K0 meets all critical electrical parameters: 82 kOhms resistance, 1W power rating, and axial through hole package. PCB layout verification is required due to dimensional differences.

Q: What is the tolerance difference between these parts?

A: RC1KB82K0 specifies ±10% tolerance, while ASRM1JA82K0 specifies ±5% tolerance. The tighter tolerance of the substitute part is compatible with applications designed for the original ±10% specification.

Q: Are there temperature range considerations for substitution?

A: RC1KB82K0 operates from -55°C to 125°C. ASRM1JA82K0 extends the upper limit to 155°C. Both parts cover the original operating range, making the substitute suitable for existing thermal requirements.

Q: Do the physical dimensions affect PCB compatibility?

A: RC1KB82K0 measures 0.224" diameter by 0.563" length. ASRM1JA82K0 measures 0.157" diameter by 0.433" length. The substitute is smaller and may require PCB footprint adjustment for space-constrained layouts.

Q: Are both parts compliant with current regulatory standards?

A: Yes, both RC1KB82K0 and ASRM1JA82K0 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
