Substitute Part Grouping Explanation

Substitution eligibility for the CB10JB15R0 is determined by the following critical parameters:

• Resistance value: 15 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 and moisture resistant construction (required)
• Regulatory compliance: ROHS3 compliant (required)

The SQPW1015RJ from TE Connectivity Passive Product meets all substitution criteria with identical electrical specifications and equivalent mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both CB10JB15R0 and SQPW1015RJ are active production components with ROHS3 compliance and REACH unaffected status. The SQPW1015RJ offers higher inventory availability at 3813 units. The primary design consideration is the operating temperature range: the CB10JB15R0 supports -55°C to 275°C, while the SQPW1015RJ supports -55°C to 250°C. Applications requiring operation above 250°C must use the CB10JB15R0. For applications within the 250°C limit, both parts are functionally equivalent. The temperature coefficient difference (±200ppm/°C versus ±300ppm/°C) should be evaluated for precision applications requiring tight thermal stability.

Frequently Asked Questions (FAQ)

Q: Can SQPW1015RJ directly replace CB10JB15R0 in all applications?

A: Direct substitution is valid for applications operating within -55°C to 250°C. Applications requiring operation above 250°C must use CB10JB15R0 due to its extended upper temperature limit of 275°C.

Q: Are the physical dimensions compatible between these parts?

A: Both parts use axial through-hole packaging with 2 terminations. The CB10JB15R0 has a square cross-section (9.50mm x 48.00mm length), while the SQPW1015RJ has a rectangular cross-section (10.00mm x 9.00mm x 48.00mm length). Both fit standard axial component footprints.

Q: What is the significance of the temperature coefficient difference?

A: The CB10JB15R0 has ±200ppm/°C while SQPW1015RJ has ±300ppm/°C. For precision circuits with tight resistance tolerance requirements across temperature ranges, the lower coefficient of CB10JB15R0 provides superior stability.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both CB10JB15R0 and SQPW1015RJ are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards.

Q: Which part should be selected for new designs?

A: Selection depends on application temperature requirements and thermal stability needs. For standard applications within 250°C, SQPW1015RJ offers better availability. For extended temperature or precision applications, CB10JB15R0 is the appropriate choice.
