Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB5JB4R70 is determined by strict equivalence in the following parameters: resistance value (4.7 Ohms), tolerance (±5%), power rating (5W), composition (wirewound), and package configuration (axial). The substitute part SQPW54R7J meets all primary electrical requirements. Variations in temperature coefficient (±300ppm/°C vs. ±200ppm/°C) and maximum operating temperature (-55°C ~ 250°C vs. -55°C ~ 275°C) are within acceptable ranges for this component category. Both parts maintain identical RoHS3 compliance and safety feature specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CB5JB4R70 and SQPW54R7J are Active status components with ROHS3 compliance and identical safety certifications. Selection between these parts is based on application-specific temperature requirements and inventory availability. The CB5JB4R70 supports operation to 275°C maximum, while the SQPW54R7J operates to 250°C maximum. Applications requiring sustained operation above 250°C require the CB5JB4R70. For applications within the -55°C ~ 250°C range, either part is electrically and mechanically compatible. The SQPW54R7J offers higher inventory availability at 2702 units.

Frequently Asked Questions (FAQ)

Q: Can SQPW54R7J replace CB5JB4R70 in all applications?

A: SQPW54R7J is compatible for applications operating within -55°C ~ 250°C. Applications requiring operation above 250°C must use CB5JB4R70.

Q: Are the physical dimensions compatible between these parts?

A: Both parts use axial package configuration. CB5JB4R70 dimensions are 0.374" Square x 0.866" L (9.50mm x 22.00mm). SQPW54R7J dimensions are 0.394" x 0.354" Rectangular x 0.866" L (10.00mm x 9.00mm x 22.00mm). Verify PCB layout clearances for the rectangular cross-section of SQPW54R7J.

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

A: CB5JB4R70 has ±200ppm/°C while SQPW54R7J has ±300ppm/°C. For precision applications with tight resistance tolerance requirements across temperature ranges, CB5JB4R70 provides superior stability.

Q: Are both parts RoHS compliant?

A: Yes, both CB5JB4R70 and SQPW54R7J are ROHS3 Compliant.

Q: What are the key electrical specifications that must match for substitution?

A: Resistance (4.7 Ohms), tolerance (±5%), power rating (5W), and composition (wirewound) must remain constant. Package type (axial) and safety features (flame proof, moisture resistant) must also be maintained.
