810F15R Equivalent & Substitute Parts

Part Overview

The 810F15R is a 15 Ohms ±1% 10W wirewound chassis mount resistor manufactured by Ohmite, part of the Metal-Mite®89 series. This component is designed for applications requiring precision resistance with high power dissipation capability in a compact flanged aluminum housing with solder lug terminations.

The 810F15R is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production builds, repairs, and system upgrades where this specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 810F15R are identified based on strict electrical and mechanical parameter matching within the Metal-Mite®89 series classification. The substitution criteria are:

• Resistance value: 15 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Housing: Aluminum with flanged mounting
• Termination: Solder lugs
• Package configuration: Axial, Box

The 810F15RE meets all these criteria and is therefore a direct electrical and mechanical equivalent within the Metal-Mite®89 series.

Parameter Comparison

Engineering Selection Recommendations

The 810F15RE is a direct functional equivalent to the 810F15R for applications requiring 15 Ohms ±1% at 10W with wirewound composition and ±20ppm/°C temperature stability. Both components share identical electrical specifications and are part of the same Metal-Mite®89 series.

The 810F15RE offers the advantage of active product status and RoHS compliance, making it suitable for new designs and applications subject to environmental regulations. The 810F15R, being obsolete and RoHS non-compliant, is no longer recommended for new production.

Physical dimensions differ slightly between the two parts. The 810F15RE is marginally larger in length, width, and height. PCB layout and mechanical clearance must be verified before substitution to ensure the component fits within the available mounting space.

Frequently Asked Questions (FAQ)

Q: Can the 810F15RE be used as a direct replacement for the 810F15R?

A: Yes. Both components have identical electrical specifications: 15 Ohms ±1%, 10W power rating, wirewound composition, and ±20ppm/°C temperature coefficient. They share the same Metal-Mite®89 series designation and use identical solder lug terminations with flanged aluminum housing.

Q: What are the physical differences between these parts?

A: The 810F15RE is slightly larger than the 810F15R. Length increases from 0.750" to 0.783", width from 0.812" to 0.827", and seated height from 0.400" to 0.433". Verify PCB layout and mechanical clearance before substitution.

Q: Does the 810F15RE meet RoHS requirements?

A: Yes. The 810F15RE is RoHS compliant. The original 810F15R is RoHS non-compliant. If RoHS compliance is required for your application, the 810F15RE is the appropriate choice.

Q: Are there any operating temperature differences?

A: The 810F15R specifies an operating temperature range of -55°C to 275°C. The 810F15RE does not provide an explicit operating temperature range in the available data. Both components share the same ±20ppm/°C temperature coefficient specification.

Q: What is the packaging difference?

A: The 810F15R is supplied in standard packaging. The 810F15RE is supplied in bulk packaging. Confirm packaging requirements for your procurement process.
