Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VM7JB180R is determined by strict equivalence across the following parameters:

• Resistance value: 180 Ohms
• Tolerance: ±5%
• Power rating: 7W
• Composition: Wirewound
• Package configuration: Radial lead
• Temperature coefficient: ±300ppm/°C
• Operating temperature range: -55°C ~ 250°C
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The SQMW7180RJ from TE Connectivity Passive Product meets all specified electrical and mechanical parameters, qualifying it as a manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The SQMW7180RJ qualifies as a direct substitute for the VM7JB180R based on electrical parameter equivalence and regulatory compliance alignment. Both components maintain ROHS3 Compliant and REACH Unaffected status. Physical dimensions are within acceptable tolerance for radial lead through-hole applications, with minor variations in width (0.50mm difference) and height (0.19mm difference) that do not impact PCB layout compatibility for standard radial component footprints. Component selection between these parts may be determined by supplier availability, lead time, or inventory requirements.

Frequently Asked Questions (FAQ)

Q: Can SQMW7180RJ be used as a direct replacement for VM7JB180R in existing designs?

A: Yes. Both components share identical electrical specifications (180 Ohms ±5%, 7W, ±300ppm/°C, -55°C ~ 250°C operating range) and equivalent mechanical packaging (radial lead configuration). Physical dimension variations are minor and compatible with standard radial component PCB footprints.

Q: Are there differences in physical dimensions between these parts?

A: Minor dimensional variations exist. The SQMW7180RJ has a width of 0.354" (9.00mm) compared to 0.374" (9.50mm) for the VM7JB180R, and a maximum seated height of 1.575" (40.00mm) versus 1.594" (40.50mm). These differences do not affect compatibility with standard radial resistor footprints.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the VM7JB180R and SQMW7180RJ are ROHS3 Compliant and REACH Unaffected, meeting equivalent environmental and safety standards.

Q: What determines substitution eligibility for this resistor category?

A: Substitution is based on matching resistance value, tolerance, power rating, composition type, package configuration, temperature coefficient, operating temperature range, and regulatory compliance status. All specified parameters must align for a component to qualify as an equivalent substitute.
