Substitute Part Grouping Explanation

Substitution eligibility for the CB5JB6R80 is determined by strict equivalence across the following parameters:

• Resistance value: 6.8 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Features: Flame proof and moisture resistant construction
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification

The SQPW56R8J from TE Connectivity Passive Product meets all primary electrical and mechanical requirements for direct substitution. Both parts share identical resistance, tolerance, power rating, and axial package format. Compliance certifications align across both components.

Parameter Comparison

Engineering Selection Recommendations

Both the CB5JB6R80 and SQPW56R8J maintain Active product status and satisfy ROHS3 compliance requirements. Selection between these components should be based on application-specific thermal requirements. The CB5JB6R80 supports operation to 275°C with a temperature coefficient of ±200ppm/°C, while the SQPW56R8J operates to 250°C with ±300ppm/°C. Applications requiring maximum temperature stability and extended upper operating temperature should specify the CB5JB6R80. Applications with thermal requirements within the 250°C limit may utilize the SQPW56R8J. Both components carry identical regulatory classifications (EAR99, REACH Unaffected) and are suitable for equivalent circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can SQPW56R8J replace CB5JB6R80 in all applications?

A: The SQPW56R8J is electrically and mechanically equivalent for applications operating within -55°C to 250°C. Applications requiring operation above 250°C or demanding the tighter temperature coefficient of ±200ppm/°C require the CB5JB6R80.

Q: What are the physical dimension differences between these parts?

A: The CB5JB6R80 measures 0.374" Square x 0.866" L (9.50mm x 22.00mm). The SQPW56R8J measures 0.394" x 0.354" Rectangular x 0.866" L (10.00mm x 9.00mm x 22.00mm). Both maintain the same axial lead length of 0.866" (22.00mm), ensuring compatibility with standard through-hole PCB layouts.

Q: Are packaging differences significant for procurement?

A: The CB5JB6R80 is supplied in Tray packaging, while SQPW56R8J is supplied in Bulk packaging. This affects handling and storage procedures but does not impact electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CB5JB6R80 and SQPW56R8J are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

Q: What is the primary difference between these substitute parts?

A: The primary differences are maximum operating temperature (275°C vs. 250°C) and temperature coefficient (±200ppm/°C vs. ±300ppm/°C). Electrical specifications—resistance, tolerance, and power rating—are identical.
