Substitute Part Grouping Explanation

Substitution eligibility for the CB10JB33R0 is determined by the following critical parameters:

• Resistance value: 33 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)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification
• Termination count: 2 (exact match required)

The substitute part SQPW1033RJ meets all critical electrical and mechanical parameters. Variations in temperature coefficient and maximum operating temperature are within acceptable ranges for equivalent substitution.

Parameter Comparison

Engineering Selection Recommendations

Both CB10JB33R0 and SQPW1033RJ are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application-specific requirements:

The CB10JB33R0 offers a wider operating temperature range (-55°C to 275°C) and lower temperature coefficient (±200ppm/°C), making it suitable for high-temperature applications or circuits requiring tighter thermal stability.

The SQPW1033RJ from TE Connectivity provides equivalent electrical performance with slightly higher temperature coefficient (±300ppm/°C) and maximum operating temperature of 250°C. This part is appropriate for standard industrial and commercial applications within the specified temperature range.

Both parts carry identical resistance, tolerance, power rating, and safety certifications. Substitution is valid when application temperature requirements do not exceed 250°C.

Frequently Asked Questions (FAQ)

Q: Can SQPW1033RJ replace CB10JB33R0 in all applications?

A: SQPW1033RJ is a valid substitute when the application operating temperature does not exceed 250°C. If your circuit operates above 250°C, the CB10JB33R0 is required due to its 275°C maximum rating.

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

A: The CB10JB33R0 has a temperature coefficient of ±200ppm/°C while SQPW1033RJ is ±300ppm/°C. In applications requiring high precision across temperature ranges, the lower coefficient of the CB10JB33R0 provides better resistance stability. For general-purpose applications, both coefficients are acceptable.

Q: Are the physical dimensions compatible?

A: Both parts use axial through-hole packaging. The CB10JB33R0 is 0.374" square × 1.890" length, while SQPW1033RJ is 0.394" × 0.354" rectangular × 1.890" length. Both fit standard axial component footprints, though slight dimensional variations exist.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both CB10JB33R0 and SQPW1033RJ are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the inventory status for each part?

A: CB10JB33R0 has 964 units in stock. SQPW1033RJ has 1216 units in stock. Availability may vary by distributor and region.
