Substitute Part Grouping Explanation

Substitution eligibility for the CB5JB33R0 is determined by the following critical parameters:

• Resistance value: 33 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, moisture resistant, safety-rated construction (exact match required)
• Regulatory compliance: ROHS3 compliant (exact match required)

The SQPW533RJ from TE Connectivity Passive Product meets all substitution criteria. Both parts share identical electrical specifications and functional characteristics within their respective operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

Both CB5JB33R0 and SQPW533RJ are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application-specific requirements:

The CB5JB33R0 provides a wider operating temperature range extending to 275°C and lower temperature coefficient at ±200ppm/°C, suitable for high-temperature applications requiring tighter thermal stability.

The SQPW533RJ operates to 250°C with a temperature coefficient of ±300ppm/°C and is available in higher inventory quantities, making it suitable for standard industrial applications where the reduced upper temperature limit and slightly higher thermal drift are acceptable.

Both parts satisfy identical electrical and mechanical requirements for 33 Ohm, 5W, ±5% tolerance wirewound resistor applications in axial through-hole configurations.

Frequently Asked Questions (FAQ)

Q: Can SQPW533RJ replace CB5JB33R0 in all applications?

A: SQPW533RJ is electrically and mechanically compatible with CB5JB33R0 for applications operating at temperatures up to 250°C. Applications requiring operation above 250°C must use CB5JB33R0.

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

A: CB5JB33R0 has a temperature coefficient of ±200ppm/°C while SQPW533RJ is ±300ppm/°C. This difference affects resistance stability across temperature variations. Applications requiring tighter thermal stability should specify CB5JB33R0.

Q: Are the physical dimensions identical?

A: Both parts use axial through-hole packaging. CB5JB33R0 dimensions are 0.374" Square x 0.866" L (9.50mm x 22.00mm). SQPW533RJ dimensions are 0.394" x 0.354" Rectangular x 0.866" L (10.00mm x 9.00mm x 22.00mm). Verify PCB layout compatibility before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both CB5JB33R0 and SQPW533RJ are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: Which part should be selected for new designs?

A: Selection depends on application temperature requirements and thermal stability needs. For maximum operating temperature capability and lowest thermal drift, specify CB5JB33R0. For standard industrial applications with adequate inventory availability, SQPW533RJ is suitable.
