Substitute Part Grouping Explanation

Substitution for the Ohmite 805F15K is determined by strict equivalence across the following parameters:

• Resistance value: 15 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Wirewound (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Housing type: Aluminum (exact match required)
• Mounting feature: Flanges (exact match required)
• Lead style: Solder Lugs (exact match required)
• Package type: Axial, Box (exact match required)

The identified substitute parts meet all core electrical and mechanical parameters. Power rating variations (5W to 7.5W) are acceptable in substitution as higher power ratings provide equivalent or superior performance in the same physical envelope. Physical dimensions remain consistent across all qualified substitutes, ensuring direct mechanical compatibility in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The Vishay Dale RH00515K00FC02 is an active production component with equivalent electrical specifications and identical physical dimensions to the obsolete Ohmite 805F15K. The 7.5W power rating provides increased thermal margin. This part is RoHS non-compliant, matching the compliance status of the original component. The operating temperature range extends to 250°C, which is 25°C lower than the original specification.

The Riedon UAL5-15KF8 is an active production component with ROHS3 compliance certification, suitable for applications requiring regulatory compliance. This part maintains the full -55°C ~ 275°C operating temperature range of the original component and provides 7.5W power rating. Physical dimensions are within 0.002" of the original specification, ensuring mechanical compatibility. Additional features include current sense capability, flame proof construction, pulse withstanding, and safety certifications.

Both substitute parts are mechanically and electrically compatible with the original Ohmite 805F15K in standard applications. Selection between substitutes depends on compliance requirements and operating temperature constraints specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Dale RH00515K00FC02 directly replace the Ohmite 805F15K?

A: Yes. Both components share identical resistance, tolerance, temperature coefficient, housing type, mounting features, lead style, and package type. The 7.5W power rating of the substitute exceeds the 5W original specification. Physical dimensions are identical. The operating temperature range of the substitute extends to 250°C, which is 25°C lower than the original.

Q: Can the Riedon UAL5-15KF8 directly replace the Ohmite 805F15K?

A: Yes. Both components share identical resistance, tolerance, temperature coefficient, housing type, mounting features, lead style, and package type. The 7.5W power rating of the substitute exceeds the 5W original specification. Physical dimensions are within 0.002" of the original. The operating temperature range matches the original at -55°C ~ 275°C.

Q: What is the primary difference between the two substitute parts?

A: The Riedon UAL5-15KF8 is ROHS3 compliant and maintains the full operating temperature range of the original component. The Vishay Dale RH00515K00FC02 is RoHS non-compliant and has a maximum operating temperature of 250°C. Both provide equivalent electrical performance and mechanical fit.

Q: Are there any dimensional concerns with substitution?

A: Physical dimensions across all three parts are within 0.002" of each other. Height differences range from 0.330" to 0.335", which is negligible for standard chassis mount applications. All parts use identical flanged mounting and solder lug termination.

Q: Does the higher power rating of the substitute parts affect compatibility?

A: No. A higher power rating in the same physical package indicates improved thermal performance. The substitute parts will operate at lower temperatures under identical load conditions compared to the original 5W component.
