Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB15JB33R0 is determined by the following critical parameters:

• Resistance value: 33 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 15W (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 SQPW1533RJ meets all substitution criteria with identical electrical specifications and equivalent mechanical construction.

Parameter Comparison

Engineering Selection Recommendations

Both CB15JB33R0 and SQPW1533RJ are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application-specific operating temperature requirements. The CB15JB33R0 supports operation to 275°C, while the SQPW1533RJ operates to 250°C. For applications requiring the extended upper temperature limit, the CB15JB33R0 is the appropriate selection. For standard industrial applications within the 250°C range, either part provides equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can SQPW1533RJ replace CB15JB33R0 in all applications?

A: SQPW1533RJ is electrically and mechanically equivalent for applications operating at or below 250°C. Applications requiring operation above 250°C must use CB15JB33R0.

Q: Are the physical dimensions compatible?

A: Both parts use axial through-hole packaging with 2 terminations. The CB15JB33R0 has a 0.512" square cross-section, while SQPW1533RJ has a 0.492" x 0.453" rectangular cross-section. Both are 1.890" in length. Verify PCB layout compatibility before substitution.

Q: What is the difference in temperature coefficient?

A: CB15JB33R0 has a temperature coefficient of ±200ppm/°C, while SQPW1533RJ is ±300ppm/°C. For precision applications with tight tolerance requirements across temperature ranges, the lower coefficient of CB15JB33R0 may be preferred.

Q: Are both parts RoHS compliant?

A: Yes, both CB15JB33R0 and SQPW1533RJ are ROHS3 compliant and REACH unaffected.

Q: What inventory levels are available?

A: CB15JB33R0 has 969 units in stock. SQPW1533RJ has 1910 units in stock.
