Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VM5JB39R0 are qualified based on the following critical parameters:

• Electrical Equivalence: Identical resistance value (39 Ohms) and tolerance (±5%)
• Power Capacity: Matching 5W power rating for equivalent thermal performance
• Composition & Construction: Wirewound technology with radial package configuration
• Environmental Characteristics: Flame-proof and moisture-resistant properties maintained
• Temperature Performance: Operating range of -55°C to 250°C with ±300ppm/°C temperature coefficient
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status
• Mechanical Compatibility: Radial termination with compatible physical dimensions

The SQMW539RJ from TE Connectivity Passive Product meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the VM5JB39R0 and SQMW539RJ maintain Active product status and full ROHS3 compliance with REACH unaffected designation. Selection between these parts should be based on:

• Availability: SQMW539RJ currently has higher inventory (1817 units) compared to VM5JB39R0 (847 units)
• Supply Chain Continuity: Both manufacturers maintain active production status
• Regulatory Requirements: Both parts satisfy identical compliance requirements for ROHS3 and REACH
• Physical Fit: Width dimension variance (9.50mm vs 9.00mm) is within typical PCB layout tolerances for radial components; height and length are identical

Frequently Asked Questions (FAQ)

Q: Can SQMW539RJ be used as a direct replacement for VM5JB39R0?

A: Yes. Both parts share identical electrical specifications (39 Ohms, ±5%, 5W), composition (wirewound), package type (radial), operating temperature range (-55°C to 250°C), and regulatory compliance (ROHS3, REACH unaffected). Physical dimensions are compatible for standard PCB applications.

Q: What is the significance of the width dimension difference (9.50mm vs 9.00mm)?

A: The 0.5mm width variance is within standard manufacturing tolerances for radial resistor packages and does not affect electrical performance or mechanical compatibility in typical circuit board layouts. Both components maintain identical length (13.00mm) and height (26.00mm).

Q: Are the flame-proof and moisture-resistant properties identical between both parts?

A: Yes. Both VM5JB39R0 and SQMW539RJ are specified with identical flame-proof, moisture-resistant, and safety features as part of their wirewound construction.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications.

Q: What is the temperature coefficient significance for these parts?

A: Both parts maintain ±300ppm/°C temperature coefficient across the full operating range of -55°C to 250°C, ensuring stable resistance performance in temperature-variable applications.
