Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB10JB6R80 is determined by strict equivalence across the following parameters:

• Resistance value: 6.8 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 10W (exact match required)
• Package type: Axial (exact match required)
• Composition: Wirewound (exact match required)
• Features: Flame Proof, Moisture Resistant, Safety (all required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification

The substitute part SQPW106R8J from TE Connectivity Passive Product meets all mandatory electrical and mechanical criteria. Both parts are active products with current inventory availability and identical regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

Both CB10JB6R80 and SQPW106R8J are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts should account for the following differences:

The CB10JB6R80 offers a lower temperature coefficient (±200ppm/°C) and extended maximum operating temperature (275°C versus 250°C), providing superior thermal stability in high-temperature applications. The SQPW106R8J features slightly different physical dimensions (rectangular cross-section 10.00mm x 9.00mm versus square 9.50mm), which may affect board layout compatibility depending on PCB design constraints.

Both parts maintain identical electrical specifications (6.8 Ohms, ±5%, 10W) and safety features (flame proof, moisture resistant). Component selection should be based on thermal performance requirements and available PCB footprint space.

Frequently Asked Questions (FAQ)

Q: Can SQPW106R8J replace CB10JB6R80 in all applications?

A: SQPW106R8J is electrically equivalent for resistance, tolerance, and power rating. However, verify that the operating temperature range (-55°C to 250°C for SQPW106R8J versus -55°C to 275°C for CB10JB6R80) meets your application requirements. Additionally, confirm that the different physical dimensions (rectangular versus square cross-section) fit your PCB layout.

Q: What are the key differences between these parts?

A: The primary differences are temperature coefficient (±200ppm/°C for CB10JB6R80 versus ±300ppm/°C for SQPW106R8J), maximum operating temperature (275°C versus 250°C), and physical cross-sectional dimensions. Electrical specifications and safety features are identical.

Q: Are both parts currently available?

A: Yes. CB10JB6R80 has 803 units in inventory, and SQPW106R8J has 894 units in inventory, both as new original stock.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: Which part should I select for high-temperature applications?

A: CB10JB6R80 is rated to 275°C maximum operating temperature with a lower temperature coefficient, making it more suitable for sustained high-temperature operation. SQPW106R8J is rated to 250°C maximum.
