Substitute Part Grouping Explanation

Substitute parts for the VM5JB56R0 are qualified based on the following critical parameters:

• Resistance value: 56 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Wirewound (exact match required)
• Package configuration: Radial through-hole (exact match required)
• Operating temperature range: -55°C to 250°C (exact match required)
• Temperature coefficient: ±300ppm/°C (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The SQMW556RJ from TE Connectivity Passive Product meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations
