Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB10JB1R00 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1 Ohms
• Tolerance: ±5%
• Power dissipation: 10W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification

The SQPW101R0J from TE Connectivity Passive Product meets all substitution criteria. Both parts maintain identical electrical specifications and mechanical form factors suitable for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

Both the CB10JB1R00 and SQPW101R0J are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Inventory availability: SQPW101R0J has higher stock levels (2695 units vs. 940 units)
• Temperature coefficient stability: SQPW101R0J offers superior temperature stability at ±300ppm/°C compared to ±500ppm/°C
• Maximum operating temperature: CB10JB1R00 supports operation to 275°C; SQPW101R0J to 250°C
• Physical envelope: Minor dimensional differences exist; verify PCB layout compatibility before substitution

Both parts satisfy identical electrical and regulatory requirements for direct substitution in axial wirewound resistor applications.

Frequently Asked Questions (FAQ)

Q: Can SQPW101R0J replace CB10JB1R00 in existing designs?

A: Yes. Both parts share identical resistance, tolerance, power rating, composition, and package type. Verify that the maximum operating temperature of 250°C for SQPW101R0J meets your application requirements, and confirm physical dimensions fit within your PCB layout.

Q: What are the key differences between these parts?

A: The primary differences are temperature coefficient (±300ppm/°C vs. ±500ppm/°C), maximum operating temperature (250°C vs. 275°C), and physical dimensions. Electrical performance at rated specifications is equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both CB10JB1R00 and SQPW101R0J are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the axial package configuration?

A: Axial package refers to through-hole resistors with leads extending from opposite ends of the component body, suitable for insertion into PCB holes or breadboard applications.

Q: Can these parts be used interchangeably on the same PCB?

A: Direct electrical interchangeability is confirmed. Physical dimensions differ slightly; verify that both parts fit within your PCB mounting holes and clearance specifications before production implementation.
