Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L100J5R0 are qualified based on strict equivalence across the following critical parameters: resistance value (5 Ohms), tolerance (±5%), power rating (100W), composition (wirewound), temperature coefficient (±400ppm/°C), operating temperature range (-55°C to 350°C), housing type (vitreous enamel coated), package configuration (radial tubular), lead style (solder lugs), and physical dimensions. All identified substitutes maintain these specifications within the allowed tolerances for this product category. Substitution is valid where mechanical fit, electrical performance, and thermal characteristics remain equivalent across the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

L100J5R0E (Ohmite) is a direct equivalent within the same manufacturer's product line, differing only in packaging format (bulk versus standard) and RoHS compliance status. This part is ROHS3 compliant, providing regulatory advantage for applications subject to RoHS requirements.

FVT10006E5R000JE (Vishay Huntington Electric Inc.) is a cross-manufacturer substitute offering equivalent electrical and thermal performance. Dimensional variance is minimal (0.750" diameter versus 0.752"), remaining within mechanical tolerance for standard chassis mount applications. This part is ROHS3 compliant and represents an alternative sourcing option from an established manufacturer in the wirewound resistor category.

Selection between substitutes should be based on procurement availability, supply chain requirements, and regulatory compliance mandates specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can L100J5R0E be used as a direct replacement for L100J5R0?

A: Yes. Both parts are manufactured by Ohmite and share identical electrical specifications, temperature characteristics, and physical dimensions. The primary difference is packaging format and RoHS compliance status.

Q: Is FVT10006E5R000JE mechanically compatible with L100J5R0?

A: Yes. The dimensional difference (0.750" versus 0.752" diameter) is within standard mechanical tolerance for chassis mount applications. All other mechanical parameters, including length, lead style, and mounting features, are equivalent.

Q: What is the significance of RoHS compliance differences?

A: L100J5R0 is RoHS non-compliant, while L100J5R0E and FVT10006E5R000JE are ROHS3 compliant. Selection depends on regulatory requirements applicable to the end product and market jurisdiction.

Q: Are all three parts suitable for the full -55°C to 350°C operating range?

A: Yes. All three parts maintain the specified temperature coefficient (±400ppm/°C) and operating temperature range across the full specification envelope.

Q: What is the difference between bulk and standard packaging?

A: L100J5R0E is supplied in bulk packaging, while L100J5R0 uses standard packaging. Electrical and mechanical specifications remain identical; packaging format affects only procurement and handling procedures.

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

A: Yes. All three parts are rated for 100W continuous operation and maintain equivalent thermal performance characteristics across the specified operating temperature range.
