Substitute Part Grouping Explanation

Substitution eligibility for the CB7JB22R0 is determined by the following critical parameters:

• Resistance value: 22 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 7W (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 SQPW722RJ meets all substitution criteria with identical electrical specifications and equivalent mechanical form factor, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CB7JB22R0 and SQPW722RJ are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts should be based on application-specific thermal requirements. The CB7JB22R0 supports operation to 275°C with a temperature coefficient of ±200ppm/°C, while the SQPW722RJ operates to 250°C with ±300ppm/°C. For applications requiring maximum temperature headroom or tighter temperature stability, the CB7JB22R0 is the primary choice. The SQPW722RJ serves as a functional equivalent for standard operating conditions within the -55°C to 250°C range.

Frequently Asked Questions (FAQ)

Q: Can SQPW722RJ directly replace CB7JB22R0 in all applications?

A: Direct replacement is possible for applications operating within -55°C to 250°C. Applications requiring operation above 250°C or demanding temperature coefficient stability better than ±300ppm/°C require the CB7JB22R0.

Q: Are the physical dimensions compatible between these parts?

A: Both parts use axial through-hole packaging with 1.378" length. The CB7JB22R0 has a 0.374" square cross-section, while the SQPW722RJ has a 0.394" x 0.354" rectangular cross-section. Both fit standard 0.1" pitch PCB layouts.

Q: Do both parts meet the same safety and environmental standards?

A: Yes. Both CB7JB22R0 and SQPW722RJ are ROHS3 compliant, REACH unaffected, and feature flame-proof and moisture-resistant construction with safety certification.

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

A: The CB7JB22R0 has a temperature coefficient of ±200ppm/°C, while the SQPW722RJ is ±300ppm/°C. This difference affects resistance stability across temperature variations. Applications with strict tolerance requirements over temperature should prioritize the lower coefficient value.
