Substitute Part Grouping Explanation

Substitution eligibility for the CB2JB1R00 is determined by the following critical parameters:

• Resistance value: 1 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Regulatory compliance: ROHS3 Compliant (minimum requirement)

The substitute part PNP200JR-52-1R meets all mandatory electrical specifications and regulatory requirements, making it functionally equivalent for direct replacement in applications where the CB2JB1R00 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the CB2JB1R00 and PNP200JR-52-1R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement. Both parts carry active product status with established supply availability.

The PNP200JR-52-1R operates within a narrower temperature range (-40°C ~ 200°C) compared to the CB2JB1R00 (-55°C ~ 275°C). Component selection should account for the specific operating temperature requirements of the target application. The PNP200JR-52-1R features a smaller physical footprint, which may impact PCB layout considerations in space-constrained designs.

Selection between these parts should be based on application-specific temperature requirements and physical space constraints within the circuit design.

Frequently Asked Questions (FAQ)

Q: Can PNP200JR-52-1R replace CB2JB1R00 in all applications?

A: Both parts share identical electrical specifications (1 Ohm, ±5%, 2W, wirewound, axial). Substitution is valid for applications operating within the PNP200JR-52-1R temperature range of -40°C ~ 200°C. Applications requiring operation below -40°C or above 200°C must use the CB2JB1R00.

Q: What are the physical dimension differences?

A: The CB2JB1R00 measures 0.252" Square x 0.709" L (6.40mm x 18.00mm). The PNP200JR-52-1R measures 0.138" Dia x 0.354" L (4.60mm x 9.00mm). The substitute part is significantly smaller and may require PCB layout verification for proper fit.

Q: Are both parts RoHS compliant?

A: Yes, both CB2JB1R00 and PNP200JR-52-1R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the primary difference between these wirewound resistors?

A: The primary differences are operating temperature range and physical size. The CB2JB1R00 offers extended temperature capability and larger dimensions. The PNP200JR-52-1R provides a compact form factor with standard industrial temperature range coverage.

Q: How should I verify compatibility before substitution?

A: Confirm that your application's operating temperature range falls within -40°C ~ 200°C and that the smaller physical dimensions (4.60mm diameter x 9.00mm length) accommodate your PCB layout requirements.
