Substitute Part Grouping Explanation

Substitute parts for the 805F1R5 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Resistance value: 1.5 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Wirewound (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -55°C to 275°C (exact match required)
• Housing material: Aluminum (exact match required)
• Mounting feature: Flanges (exact match required)
• Lead style: Solder Lugs (exact match required)
• Physical dimensions: 0.600" L × 0.646" W, 0.330" height (exact match required)
• Series: Metal-Mite®89 (exact match required)

The 805F1R5E meets all substitution criteria and differs only in packaging configuration and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 805F1R5 and 805F1R5E are electrically and mechanically identical, with differences limited to packaging format and regulatory compliance status.

The 805F1R5E is ROHS3 compliant, making it the appropriate selection for applications subject to RoHS3 regulatory requirements or for integration into supply chains requiring RoHS3 certification. The 805F1R5 remains suitable for applications where RoHS compliance is not mandated.

Packaging differences (box versus bulk) do not affect component performance and should be selected based on procurement and assembly workflow requirements. The 805F1R5E offers higher current inventory availability at 1025 units compared to 722 units for the 805F1R5.

Frequently Asked Questions (FAQ)

Q: Are the 805F1R5 and 805F1R5E electrically interchangeable?

A: Yes. Both parts are identical in resistance value (1.5 Ohms), tolerance (±1%), power rating (5W), temperature coefficient (±50ppm/°C), operating temperature range (-55°C to 275°C), and all mechanical specifications including dimensions, housing material, mounting features, and lead style.

Q: What is the difference between the 805F1R5 and 805F1R5E?

A: The primary differences are packaging format (box versus bulk) and compliance certifications. The 805F1R5E is ROHS3 compliant, while the 805F1R5 is RoHS non-compliant. Electrical and mechanical performance are identical.

Q: Which part should I select for RoHS3-regulated applications?

A: The 805F1R5E is ROHS3 compliant and is the correct selection for applications requiring RoHS3 certification or compliance with RoHS3 regulatory frameworks.

Q: Does packaging format affect component performance?

A: No. Box and bulk packaging formats do not affect electrical performance, thermal characteristics, or mechanical compatibility. Selection should be based on procurement requirements and assembly processes.

Q: Are both parts currently in production?

A: Yes. Both the 805F1R5 and 805F1R5E are active products with current inventory availability.
