Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 810F2R0E is determined by the following critical parameters:

• Resistance value: 2 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Mounting feature: Flanges (exact match required)
• Lead style: Solder Lugs (exact match required)
• Housing type: Aluminum (exact match required)

The Riedon UAL10-2RF8 meets all critical electrical and mechanical parameters, qualifying it as a direct substitute within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

Both the 810F2R0E and UAL10-2RF8 are Active status components meeting identical electrical specifications. Selection between these parts should be based on the following factors:

The Ohmite 810F2R0E maintains current inventory of 1163 units and carries RoHS Compliance certification suitable for standard applications.

The Riedon UAL10-2RF8 provides ROHS3 Compliance and REACH Unaffected status, offering enhanced regulatory alignment for applications with stricter environmental requirements. This part also specifies an operating temperature range of -55°C to 275°C. Physical dimensions are slightly smaller (0.752" x 0.799" versus 0.783" x 0.827"), which may provide advantages in space-constrained layouts. Current inventory stands at 1184 units.

Both components carry identical electrical parameters and are suitable for direct substitution in current sensing and power dissipation applications requiring 2 Ohm, 10W wirewound resistors with ±1% tolerance.

Frequently Asked Questions (FAQ)

Q: Can the UAL10-2RF8 replace the 810F2R0E in existing designs?

A: Yes. Both parts share identical resistance (2 Ohms), tolerance (±1%), power rating (10W), temperature coefficient (±50ppm/°C), composition (wirewound), mounting features (flanges), and lead style (solder lugs). Physical dimensions differ slightly, with the UAL10-2RF8 being marginally smaller. Verify PCB layout clearances before substitution.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires exact matching of resistance value, tolerance, power rating, composition type, temperature coefficient, mounting feature, lead style, and housing material. All these parameters are identical between the 810F2R0E and UAL10-2RF8.

Q: Are there compliance differences between these parts?

A: The 810F2R0E carries RoHS Compliance certification. The UAL10-2RF8 carries ROHS3 Compliance and REACH Unaffected status, providing enhanced regulatory coverage for applications with stricter environmental standards.

Q: What is the operating temperature range for each part?

A: The 810F2R0E operating temperature range is not specified in available documentation. The UAL10-2RF8 specifies -55°C to 275°C operating range. Both maintain a temperature coefficient of ±50ppm/°C.

Q: Are there physical dimension considerations for substitution?

A: The 810F2R0E measures 0.783" L x 0.827" W x 0.433" H (19.90mm x 21.00mm x 11.00mm). The UAL10-2RF8 measures 0.752" L x 0.799" W x 0.417" H (19.10mm x 20.30mm x 10.60mm). The UAL10-2RF8 is slightly smaller. Verify PCB footprint and clearance compatibility before design implementation.

Q: What is the moisture sensitivity level for both parts?

A: Both the 810F2R0E and UAL10-2RF8 carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
