Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB5JB15R0 is determined by strict equivalence across the following parameters:

• Resistance value: 15 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (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 SQPW515RJ from TE Connectivity Passive Product meets all substitution criteria. Both parts share identical electrical specifications, axial package configuration, and equivalent environmental protection features. Differences in temperature coefficient (±300ppm/°C vs ±200ppm/°C) and maximum operating temperature (250°C vs 275°C) remain within acceptable substitution parameters for this resistor category.

Parameter Comparison

Engineering Selection Recommendations

Both CB5JB15R0 and SQPW515RJ are active production components with ROHS3 compliance and equivalent safety certifications. Selection between these parts is based on availability and supply chain requirements. The CB5JB15R0 offers a wider operating temperature range (275°C maximum) and tighter temperature coefficient specification (±200ppm/°C), making it suitable for applications requiring extended thermal performance. The SQPW515RJ provides equivalent functionality with higher inventory availability (3025 units in stock versus 787 units). Both parts are suitable for direct substitution in axial wirewound resistor applications requiring 15 Ohm, 5W specifications with flame-proof and moisture-resistant construction.

Frequently Asked Questions (FAQ)

Q: Can SQPW515RJ replace CB5JB15R0 in all applications?

A: Yes, for applications operating within the SQPW515RJ temperature range (-55°C to 250°C). If your circuit requires operation above 250°C, the CB5JB15R0 with its 275°C maximum rating is required.

Q: What is the difference in temperature coefficient between these parts?

A: CB5JB15R0 has ±200ppm/°C while SQPW515RJ has ±300ppm/°C. This means the CB5JB15R0 maintains more stable resistance across temperature variations. For precision applications with tight tolerance requirements, the CB5JB15R0 is preferred.

Q: Are the physical dimensions identical?

A: Both parts use axial package configuration. CB5JB15R0 dimensions are 0.374" Square x 0.866" L (9.50mm x 22.00mm). SQPW515RJ dimensions are 0.394" x 0.354" Rectangular x 0.866" L (10.00mm x 9.00mm x 22.00mm). Both fit standard axial through-hole PCB layouts.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both CB5JB15R0 and SQPW515RJ are ROHS3 compliant with equivalent flame-proof and moisture-resistant safety features. Both carry EAR99 ECCN classification.

Q: Which part should I choose for new designs?

A: Selection depends on application requirements and supply availability. For maximum temperature performance and tighter tolerance specifications, specify CB5JB15R0. For general applications with higher stock availability, SQPW515RJ is suitable.
