Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC1KB560R is determined by the following critical parameters:

• Resistance Value: 560 Ohms (exact match required)
• Power Rating: 1W (exact match required)
• Package Type: Axial (exact match required)
• Operating Temperature Range: Minimum -55°C to 125°C coverage
• Regulatory Compliance: ROHS3 Compliant status

The ASRM1JA560R qualifies as a direct substitute based on matching resistance, power rating, and axial package configuration. While the substitute features improved tolerance (±5% versus ±10%) and an extended upper operating temperature limit (155°C versus 125°C), these represent performance enhancements rather than deviations from the original specification.

Parameter Comparison

Engineering Selection Recommendations

The ASRM1JA560R is the qualified substitute for the obsolete RC1KB560R. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The substitute is currently in active production with confirmed inventory availability (673 pcs), providing supply chain continuity for the RC1KB560R.

The transition from carbon composition to metal film construction in the substitute introduces improved tolerance performance (±5% versus ±10%) and extended temperature capability (-55°C to 155°C versus -55°C to 125°C). Both components share identical axial package geometry and 1W power rating, supporting direct board-level replacement without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the ASRM1JA560R directly replace the RC1KB560R in existing designs?

A: Yes. Both components share the same 560 Ohm resistance value, 1W power rating, and axial package configuration. The substitute meets or exceeds all electrical and mechanical parameters of the original part.

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

A: The RC1KB560R uses carbon composition construction with ±10% tolerance, while the ASRM1JA560R uses metal film construction with ±5% tolerance. The substitute also provides an extended operating temperature range (155°C maximum versus 125°C maximum).

Q: Are there any compliance concerns with substitution?

A: No. Both components are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status.

Q: Does the axial package dimension differ between these parts?

A: Yes. The RC1KB560R measures 0.224" Dia x 0.563" L (5.70mm x 14.30mm), while the ASRM1JA560R measures 0.157" Dia x 0.433" L (4.00mm x 11.00mm). The substitute is physically smaller, which may provide layout benefits in space-constrained applications.

Q: What is the availability status of each component?

A: The RC1KB560R is obsolete with 951 pcs in stock. The ASRM1JA560R is active production with 673 pcs in stock, ensuring long-term supply continuity.
