Substitute Part Grouping Explanation

Substitution eligibility for the B8J50RE is determined by strict equivalence across the following critical parameters:

• Resistance value: 50 Ohms
• Tolerance: ±5%
• Power rating: 8W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Temperature coefficient: ±260ppm/°C
• Physical dimensions: 0.313" Dia x 1.000" L
• Termination count: 2

The B8J50R meets all electrical and mechanical requirements for direct substitution within the Brown Devil® 200 series. Both parts share identical resistance, tolerance, power handling, thermal characteristics, and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

The B8J50R functions as a parametric equivalent to the B8J50RE for applications where electrical and mechanical specifications are the primary selection criteria. Both parts maintain identical resistance, tolerance, power dissipation, thermal performance, and physical form factor within the Brown Devil® 200 series.

Selection between B8J50RE and B8J50R depends on regulatory compliance requirements. The B8J50RE carries ROHS3 compliance certification, suitable for applications subject to Restriction of Hazardous Substances directives. The B8J50R is RoHS non-compliant and should be selected only for applications where such compliance is not mandated. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can B8J50R replace B8J50RE in all applications?

A: B8J50R provides electrical and mechanical equivalence to B8J50RE. Selection depends on regulatory compliance requirements. If ROHS3 compliance is mandatory, B8J50RE is required. If RoHS compliance is not a design constraint, B8J50R is functionally equivalent.

Q: Are the physical dimensions identical between B8J50RE and B8J50R?

A: Yes. Both parts share identical dimensions of 0.313" Dia x 1.000" L (7.94mm x 25.40mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: Do both parts have the same thermal characteristics?

A: Yes. Both B8J50RE and B8J50R maintain a temperature coefficient of ±260ppm/°C, providing equivalent thermal stability across the operating range.

Q: What is the difference between B8J50RE and B8J50R?

A: The primary difference is RoHS compliance status. B8J50RE is ROHS3 compliant, while B8J50R is RoHS non-compliant. All electrical parameters, mechanical specifications, and safety features are identical.

Q: Are both parts suitable for high-temperature applications?

A: Both parts are specified with a temperature coefficient of ±260ppm/°C. Specific operating temperature limits are not provided in the technical parameters. Consult detailed datasheets for maximum operating temperature ratings.
