Substitute Part Grouping Explanation

Substitution eligibility for the VM5JB2R20 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.2 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 ~ 250°C (minimum required)
• Temperature coefficient: ±300ppm/°C (exact match required)
• Feature set: Flame Proof, Moisture Resistant, Safety (all required)
• Regulatory compliance: ROHS3 Compliant (minimum required)

The SQMW52R2J from TE Connectivity Passive Product meets all substitution criteria and qualifies as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the VM5JB2R20 and SQMW52R2J are Active product status components with identical electrical specifications and regulatory compliance certifications. Selection between these parts should be based on availability and lead time requirements. The SQMW52R2J offers higher inventory availability at 5985 units compared to 761 units for the VM5JB2R20. Both components maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility in target applications. Physical dimensions are equivalent within acceptable tolerances for radial through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can SQMW52R2J be used as a direct replacement for VM5JB2R20?

A: Yes. Both components share identical electrical specifications (2.2 Ohms ±5%, 5W), composition (wirewound), package type (radial), operating temperature range (-55°C ~ 250°C), and feature set (flame proof, moisture resistant, safety). Regulatory compliance is equivalent.

Q: Are there physical dimension differences between these parts?

A: The width dimension differs slightly: VM5JB2R20 is 9.50mm wide while SQMW52R2J is 9.00mm wide. Both maintain identical length (13.00mm) and seated height (26.00mm). This 0.50mm width variance is within acceptable tolerances for radial through-hole PCB layouts.

Q: What determines substitution eligibility for this resistor category?

A: Substitution requires exact matching of resistance value, tolerance, power rating, composition type, package configuration, operating temperature range, temperature coefficient, and feature set. Regulatory compliance certifications must meet or exceed the original specification.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both VM5JB2R20 and SQMW52R2J are rated for -55°C ~ 250°C operating temperature with ±300ppm/°C temperature coefficient, making them suitable for high-temperature circuit applications.

Q: What is the significance of the wirewound composition?

A: Wirewound construction provides the 5W power dissipation capability and contributes to the flame-proof and moisture-resistant characteristics required for safety-critical applications. This composition is essential for the specified performance envelope.
