Substitute Part Grouping Explanation

Substitution eligibility for the VM10JB8R20 is determined by strict equivalence across the following critical parameters:

• Resistance value: 8.2 Ohms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Package configuration: Radial Lead
• Operating temperature range: -55°C to 250°C
• Temperature coefficient: ±300ppm/°C
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The substitute part SQZW108R2J, manufactured by TE Connectivity Passive Product, meets all electrical and environmental specifications. Physical dimensions differ between the main part and substitute; however, both maintain radial lead configuration suitable for through-hole PCB mounting.

Parameter Comparison

Engineering Selection Recommendations

Both VM10JB8R20 and SQZW108R2J are Active status components with identical electrical specifications and full regulatory compliance. Selection between these parts should be based on:

• PCB layout constraints: Physical dimensions differ significantly. The SQZW108R2J is longer (48mm vs 16mm) but lower in height (11mm vs 36mm).
• Inventory availability: SQZW108R2J has 1897 units in stock compared to 963 units for VM10JB8R20.
• Supply chain continuity: Both manufacturers maintain Active product status, ensuring long-term availability.
• Thermal management requirements: Both parts operate across the full -55°C to 250°C range with identical temperature coefficients.

Frequently Asked Questions (FAQ)

Q: Can SQZW108R2J replace VM10JB8R20 in all applications?

A: Electrical substitution is valid when resistance, tolerance, power rating, temperature range, and composition are identical. Physical dimensions differ; PCB layout compatibility must be confirmed before implementation.

Q: What determines if a part is a valid substitute?

A: Valid substitutes maintain equivalence in resistance value, tolerance, power rating, wirewound composition, radial lead package, operating temperature range, temperature coefficient, and regulatory compliance status.

Q: Are there physical mounting differences between these parts?

A: Yes. VM10JB8R20 measures 16.00mm L × 12.00mm W with 36.00mm seated height. SQZW108R2J measures 48.00mm L × 10.00mm W with 11.00mm seated height. Both use radial lead configuration for through-hole mounting.

Q: Do both parts meet the same regulatory requirements?

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?

A: Both parts maintain ±300ppm/°C temperature coefficient across the -55°C to 250°C operating range, ensuring stable resistance performance under thermal variation.
