Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 810F1R0 is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 1 Ohms
• Tolerance: ±1%
• Composition: Wirewound
• Mounting feature: Flanges
• Lead style: Solder Lugs
• Housing type: Aluminum
• Package type: Axial, Box

Secondary Compatibility Factors:

• Power rating: Equal to or greater than 10W
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: Must encompass or match the original specification

Two substitute parts meet these criteria with varying compliance and power rating characteristics.

Engineering Selection Recommendations

Ohmite 810F1R0E is the primary direct substitute. This part maintains identical electrical specifications and physical dimensions while offering active product status and ROHS3 compliance. The transition from the obsolete 810F1R0 to the 810F1R0E represents a direct replacement with improved regulatory standing.

Vishay Dale RH0101R000FC02 serves as an alternative substitute with the following considerations: it provides increased power dissipation capability (12.5W versus 10W), maintaining all critical electrical parameters including resistance, tolerance, and temperature coefficient. The operating temperature maximum is reduced to 250°C compared to 275°C. This part is RoHS non-compliant and REACH affected, requiring evaluation against specific regulatory requirements for your application.

Selection between these substitutes depends on regulatory compliance requirements, thermal design margins, and operating temperature envelope constraints specific to your application.

Frequently Asked Questions (FAQ)

Q: Can the 810F1R0E directly replace the obsolete 810F1R0?

A: Yes. The 810F1R0E maintains identical resistance (1 Ohm), tolerance (±1%), power rating (10W), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 275°C), and physical dimensions. It is electrically and mechanically interchangeable.

Q: What is the primary difference between the Ohmite and Vishay Dale substitutes?

A: The Ohmite 810F1R0E is a direct equivalent with identical specifications. The Vishay Dale RH0101R000FC02 offers higher power rating (12.5W) but operates to a maximum temperature of 250°C instead of 275°C. Both maintain the same resistance, tolerance, and temperature coefficient.

Q: Does the higher power rating of the RH0101R000FC02 affect compatibility?

A: No. A higher power rating is compatible with applications designed for the original 10W specification. The component will operate within its thermal limits at the same power dissipation levels. However, the reduced maximum operating temperature (250°C versus 275°C) must be verified against your application requirements.

Q: What packaging differences exist between these parts?

A: The 810F1R0 ships in standard packaging (-), the 810F1R0E in Tray packaging, and the RH0101R000FC02 in Bulk packaging. All three maintain identical Axial, Box case configuration and solder lug termination.

Q: Are there RoHS compliance implications for substitution?

A: The 810F1R0E is ROHS3 compliant, while both the original 810F1R0 and the Vishay Dale RH0101R000FC02 are RoHS non-compliant. If RoHS compliance is required for your application, the 810F1R0E is the appropriate selection.
