Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L100J100 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match exactly:

• Resistance value: 100 Ohms
• Tolerance: ±5%
• Power rating: 100W
• Composition: Wirewound
• Temperature coefficient: ±260ppm/°C
• Operating temperature range: -55°C to 350°C
• Housing type: Vitreous Enamel Coated
• Lead style: Solder Lugs
• Package type: Radial, Tubular
• Mounting feature: Brackets (not included)

Two substitute parts meet these criteria: L100J100E (Ohmite, 270 series) and FVT10006E100R0JE (Vishay Huntington Electric Inc., FVT series). Both parts are functionally equivalent to the main part and maintain identical electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—L100J100, L100J100E, and FVT10006E100R0JE—are active production components with identical electrical specifications and mechanical form factors. Selection between these parts is determined by compliance requirements and availability:

L100J100 (Ohmite): Primary part with RoHS non-compliant status. Use when legacy compliance requirements or existing design specifications mandate this exact part number.

L100J100E (Ohmite): Direct equivalent from the same manufacturer with ROHS3 compliance. Provides identical performance with improved regulatory compliance. Bulk packaging available with 697 units in stock.

FVT10006E100R0JE (Vishay Huntington Electric Inc.): Cross-manufacturer equivalent with ROHS3 compliance. Maintains all electrical and mechanical specifications with minimal dimensional variance (0.750" diameter versus 0.752"). Highest inventory availability at 1033 units. Suitable for applications where multi-source qualification is required.

Frequently Asked Questions (FAQ)

Q: Can L100J100E be used as a direct replacement for L100J100?

A: Yes. L100J100E is electrically and mechanically equivalent to L100J100. Both are Ohmite 270 series components with identical resistance, tolerance, power rating, temperature coefficient, and operating range. The primary difference is ROHS3 compliance status of L100J100E.

Q: What is the dimensional difference between L100J100 and FVT10006E100R0JE?

A: The diameter differs by 0.002 inches (0.05mm). L100J100 is 0.752" diameter; FVT10006E100R0JE is 0.750" diameter. Both maintain 6.500" length. This minimal variance does not affect electrical performance or standard mounting configurations.

Q: Are all three parts suitable for the same operating temperature range?

A: Yes. All three parts operate across -55°C to 350°C with identical temperature coefficient of ±260ppm/°C.

Q: What packaging options are available?

A: L100J100 packaging is not specified. L100J100E and FVT10006E100R0JE are supplied in bulk packaging.

Q: Which part should be selected for RoHS-compliant applications?

A: Both L100J100E and FVT10006E100R0JE carry ROHS3 compliance certification. L100J100 is RoHS non-compliant and should not be used in applications requiring RoHS compliance.

Q: Can FVT10006E100R0JE be used in designs originally specified for L100J100?

A: Yes. FVT10006E100R0JE meets all electrical and mechanical requirements of L100J100. The cross-manufacturer substitution is valid for applications where multi-source qualification is acceptable.
