• Composition: Wirewound
• Package: Axial through-hole
• Features: Flame proof, moisture resistant, safety construction
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification

The SQPW10100RJ from TE Connectivity Passive Product meets all core electrical and mechanical requirements for direct substitution. Both parts share identical resistance, tolerance, power rating, and axial package configuration. Both components maintain equivalent safety certifications and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both CB10JB100R and SQPW10100RJ are Active products with equivalent ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on:

• Thermal performance requirements: CB10JB100R supports operation to 275°C versus SQPW10100RJ at 250°C maximum
• Temperature coefficient stability: CB10JB100R provides ±200ppm/°C versus ±300ppm/°C for SQPW10100RJ
• Physical envelope constraints: Dimensional differences exist between square (9.50mm) and rectangular (10.00mm x 9.00mm) cross-sections, both maintaining 1.890" axial length
• Inventory availability: SQPW10100RJ offers 4233 units versus 980 units for CB10JB100R

Frequently Asked Questions (FAQ)

Q: Can SQPW10100RJ replace CB10JB100R in all applications?

A: Direct substitution is valid for applications requiring 100 Ohms ±5% at 10W with axial through-hole mounting. Verify that the maximum operating temperature of 250°C for SQPW10100RJ meets your circuit requirements, as CB10JB100R supports 275°C operation.

Q: What are the physical differences between these parts?

A: CB10JB100R has a square cross-section (9.50mm), while SQPW10100RJ has a rectangular cross-section (10.00mm x 9.00mm). Both maintain 1.890" axial length. Confirm PCB layout and component spacing accommodate the rectangular profile of SQPW10100RJ.

Q: Are both parts RoHS compliant?

A: Yes, both CB10JB100R and SQPW10100RJ are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Q: What is the temperature coefficient difference?

A: CB10JB100R has a temperature coefficient of ±200ppm/°C, while SQPW10100RJ is ±300ppm/°C. For precision applications with tight tolerance requirements across temperature ranges, CB10JB100R provides superior stability.

Q: Which part should I select for high-temperature applications?

A: CB10JB100R is rated to 275°C, making it suitable for higher temperature environments. SQPW10100RJ is limited to 250°C maximum operating temperature.
