Parameter Comparison

Engineering Selection Recommendations

All three parts—L50J10R, L50J10RE, and FVT05006E10R00JE—are active production components with equivalent electrical and mechanical specifications. Selection between these parts may be based on the following factors:

L50J10RE (Ohmite) is ROHS3 compliant and REACH unaffected, providing regulatory alignment for applications subject to these standards. This variant maintains identical electrical performance to the L50J10R while offering improved compliance status.

FVT05006E10R00JE (Vishay Huntington Electric Inc.) is also ROHS3 compliant and provides cross-manufacturer sourcing flexibility. This part is functionally equivalent and suitable for applications requiring multi-source qualification.

The L50J10R remains available with 911 units in stock and is suitable for applications where RoHS non-compliance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can L50J10RE be used as a direct replacement for L50J10R?

A: Yes. Both parts are Ohmite 270 series wirewound chassis mount resistors with identical electrical specifications (10 Ohms ±5%, 50W, ±400ppm/°C, -55°C ~ 350°C operating range) and physical dimensions (0.563" Dia x 4.000" L). The primary difference is packaging format and RoHS compliance status. L50J10RE is ROHS3 compliant.

Q: Is the Vishay FVT05006E10R00JE compatible with the L50J10R?

A: Yes. The FVT05006E10R00JE meets all electrical and mechanical requirements for direct substitution. It is a 10 Ohms ±5% 50W wirewound resistor with identical temperature coefficient, operating range, housing type, and physical dimensions. It is ROHS3 compliant.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by matching resistance value (10 Ohms), tolerance (±5%), power rating (50W), temperature coefficient (±400ppm/°C), operating temperature range (-55°C ~ 350°C), composition (wirewound), housing type (vitreous enamel coated), package type (radial tubular), physical dimensions (0.563" Dia x 4.000" L), and lead style (solder lugs).

Q: Are there packaging differences between these parts?

A: L50J10R is supplied in standard packaging, while L50J10RE is supplied in bulk packaging. Both maintain identical component specifications and are suitable for the same circuit applications.

Q: What is the difference in RoHS compliance between these parts?

A: L50J10R is RoHS non-compliant. L50J10RE and FVT05006E10R00JE are both ROHS3 compliant. For applications subject to RoHS regulations, L50J10RE or FVT05006E10R00JE are the appropriate selections.
