Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB7JB6R80 is determined by matching the following critical parameters:

• Resistance value: 6.8 Ohms
• Tolerance: ±5%
• Power rating: 7W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The SQPW76R8J from TE Connectivity Passive Product meets all substitution criteria. Both parts maintain identical electrical specifications and axial package compatibility, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CB7JB6R80 and SQPW76R8J are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Selection between these parts should be based on availability, lead time, and application-specific thermal requirements. The CB7JB6R80 supports operation to 275°C, while the SQPW76R8J operates to 250°C. The SQPW76R8J exhibits a higher temperature coefficient (±300ppm/°C versus ±200ppm/°C), which may affect precision applications requiring tighter resistance stability across temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can SQPW76R8J replace CB7JB6R80 in existing designs?

A: Yes. Both components share identical resistance (6.8 Ohms), tolerance (±5%), power rating (7W), composition (wirewound), and axial package configuration. Functional compatibility is established for direct substitution.

Q: What are the dimensional differences between these parts?

A: CB7JB6R80 dimensions are 0.374" Square x 1.378" L (9.50mm x 35.00mm). SQPW76R8J dimensions are 0.394" x 0.354" Rectangular x 1.378" L (10.00mm x 9.00mm x 35.00mm). Both maintain the same axial lead length of 1.378" (35.00mm), ensuring PCB footprint compatibility.

Q: Are there temperature range limitations when substituting?

A: The CB7JB6R80 operates from -55°C to 275°C, while SQPW76R8J operates from -55°C to 250°C. Applications requiring operation above 250°C must use the CB7JB6R80. For applications within the -55°C to 250°C range, both parts are suitable.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both CB7JB6R80 and SQPW76R8J are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations.

Q: How do temperature coefficients affect part selection?

A: The CB7JB6R80 has a temperature coefficient of ±200ppm/°C, while SQPW76R8J is ±300ppm/°C. For applications requiring tighter resistance stability across temperature variations, the CB7JB6R80 provides superior performance.
