• Tolerance: ±5%
• Power rating: 13W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -65°C to 350°C
• Physical dimensions: 0.375" Dia × 1.781" L
• Moisture resistance feature
• Number of terminations: 2

The substitute part CW0105R000JE12 meets all electrical and mechanical parameters required for direct substitution. Differences in RoHS compliance status and REACH classification do not affect functional equivalence but may influence procurement decisions based on end-application regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both CW0105R000JB12 and CW0105R000JE12 are functionally equivalent and interchangeable for applications requiring a 5 Ohm, 13W wirewound axial resistor with moisture-resistant construction.

Selection between these parts should be based on regulatory compliance requirements:

• CW0105R000JB12 is suitable for applications where RoHS non-compliance and REACH-affected status are acceptable.
• CW0105R000JE12 is required for applications mandating ROHS3 compliance and REACH-unaffected material status.

Both parts share identical electrical characteristics, physical dimensions, and thermal performance specifications. The CW0105R000JE12 offers higher current inventory availability at 1300 units compared to 1033 units for the CW0105R000JB12.

Frequently Asked Questions (FAQ)

Q: Can CW0105R000JE12 be used as a direct replacement for CW0105R000JB12?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters including resistance, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. They are pin-compatible and footprint-compatible for PCB applications.

Q: What is the difference between these two part numbers?

A: The primary differences are compliance certifications. CW0105R000JE12 is ROHS3 compliant and REACH unaffected, while CW0105R000JB12 is RoHS non-compliant and REACH affected. Electrical and mechanical specifications are identical.

Q: Are there any thermal performance differences?

A: No. Both parts have identical temperature coefficients of ±50ppm/°C and operate across the same temperature range of -65°C to 350°C.

Q: Which part should I specify for new designs?

A: Selection depends on your application's regulatory requirements. For designs requiring ROHS3 compliance or REACH-unaffected materials, specify CW0105R000JE12. For applications without these constraints, either part is acceptable.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical axial package dimensions of 0.375" diameter by 1.781" length (9.52mm × 45.24mm).

Q: Can these parts be used in high-temperature applications?

A: Yes. Both parts are rated for continuous operation up to 350°C, making them suitable for high-temperature circuit applications.
