Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB5JB2R20 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.2 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Wirewound
• Package: Axial through-hole
• Features: Flame Proof, Moisture Resistant, Safety
• Regulatory compliance: ROHS3 Compliant

The SQPW52R2J meets all substitution criteria with identical electrical specifications and axial package configuration. Variations in physical dimensions, temperature coefficient, and maximum operating temperature do not disqualify substitution when the component operates within the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the CB5JB2R20 and SQPW52R2J maintain Active product status and full ROHS3 compliance. Selection between these parts is determined by application-specific thermal and stability requirements. The CB5JB2R20 offers superior temperature coefficient performance (±200ppm/°C) and extended maximum operating temperature (275°C), making it suitable for high-temperature applications. The SQPW52R2J provides equivalent electrical performance with higher inventory availability (1778 units). Both components satisfy identical regulatory requirements under REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can SQPW52R2J replace CB5JB2R20 in all applications?

A: Substitution is valid when the application operates within the SQPW52R2J maximum temperature limit of 250°C. Applications requiring operation above 250°C require the CB5JB2R20.

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

A: The CB5JB2R20 exhibits ±200ppm/°C while SQPW52R2J exhibits ±300ppm/°C. This affects resistance stability across temperature variations. Applications with strict resistance tolerance requirements at elevated temperatures should prioritize the CB5JB2R20.

Q: Are the physical dimensions interchangeable?

A: Both components use axial through-hole packaging. The CB5JB2R20 measures 0.374" Square x 0.866" L, while SQPW52R2J measures 0.394" x 0.354" Rectangular x 0.866" L. Verify PCB layout compatibility before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CB5JB2R20 and SQPW52R2J are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS codes.

Q: Which part should be selected for new designs?

A: Selection depends on thermal requirements and supply chain considerations. For applications below 250°C, either part is acceptable. For applications approaching or exceeding 250°C, specify CB5JB2R20.
