Substitute Part Grouping Explanation

Substitution eligibility for the CB10JB7R50 is determined by the following critical parameters:

• Resistance value: 7.5 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Features: Flame Proof, Moisture Resistant, Safety (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The substitute part SQPW107R5J from TE Connectivity Passive Product meets all critical electrical and mechanical parameters, enabling direct substitution in applications requiring equivalent performance and compliance.

Parameter Comparison

Engineering Selection Recommendations

Both CB10JB7R50 and SQPW107R5J are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component deployment. The CB10JB7R50 offers a maximum operating temperature of 275°C with a temperature coefficient of ±200ppm/°C, while the SQPW107R5J operates to 250°C with ±300ppm/°C. Selection between these parts should be based on specific application temperature requirements and thermal stability specifications. Both components are suitable for applications requiring flame-proof, moisture-resistant wirewound resistor performance in axial through-hole configurations.

Frequently Asked Questions (FAQ)

Q: Can SQPW107R5J replace CB10JB7R50 in all applications?

A: SQPW107R5J meets all critical electrical and mechanical specifications for direct substitution. However, applications operating above 250°C or requiring the tighter temperature coefficient of ±200ppm/°C should verify compatibility with the substitute part's maximum operating temperature of 250°C and temperature coefficient of ±300ppm/°C.

Q: Are the physical dimensions compatible between these parts?

A: Both parts use axial through-hole packaging. CB10JB7R50 dimensions are 0.374" Square x 1.890" L (9.50mm x 48.00mm). SQPW107R5J dimensions are 0.394" x 0.354" Rectangular x 1.890" L (10.00mm x 9.00mm x 48.00mm). Verify PCB layout and mounting clearances for the substitute part's slightly larger cross-sectional dimensions.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CB10JB7R50 and SQPW107R5J are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use.

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

A: The primary differences are operating temperature range (CB10JB7R50: -55°C to 275°C versus SQPW107R5J: -55°C to 250°C) and temperature coefficient (CB10JB7R50: ±200ppm/°C versus SQPW107R5J: ±300ppm/°C). All other electrical and mechanical parameters are identical.
