Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 805F500 is determined by strict equivalence across the following critical parameters:

• Resistance value: 500 Ohms
• Tolerance: ±1%
• Power rating: 5W
• Composition: Wirewound
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C to 275°C
• Housing material: Aluminum
• Mounting feature: Flanges
• Physical dimensions: 0.600" L x 0.646" W (15.24mm x 16.41mm)
• Height seated (max): 0.330" (8.38mm)
• Lead style: Solder Lugs

The identified substitute part 805F500E maintains complete electrical and mechanical equivalence. The primary difference is packaging configuration (Tray versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 805F500 and 805F500E are active production parts from Ohmite's Metal-Mite®89 series with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

805F500: Select this part number when standard packaging is required and RoHS non-compliance is acceptable for your application.

805F500E: Select this part number when ROHS3 compliance is mandated by design requirements or regulatory standards. This variant is available in Tray packaging and offers higher current inventory availability (1284 units versus 712 units).

Both parts are suitable for direct substitution in applications requiring 500 Ohm ±1% 5W wirewound resistors with aluminum housing and flange mounting. No electrical performance differences exist between the two variants.

Frequently Asked Questions (FAQ)

Q: Are the 805F500 and 805F500E electrically identical?

A: Yes. Both parts have identical resistance (500 Ohms), tolerance (±1%), power rating (5W), temperature coefficient (±20ppm/°C), and operating temperature range (-55°C to 275°C).

Q: What is the difference between these part numbers?

A: The primary differences are packaging configuration (Tray for 805F500E versus standard for 805F500) and RoHS compliance status (ROHS3 Compliant for 805F500E versus RoHS non-compliant for 805F500).

Q: Can I use 805F500E as a direct replacement for 805F500?

A: Yes. The 805F500E is a direct substitute with identical mechanical dimensions (0.600" L x 0.646" W, 0.330" height seated max), mounting features (flanges), and lead style (solder lugs). Verify that ROHS3 compliance does not conflict with your application requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.600" L x 0.646" W (15.24mm x 16.41mm) and maximum seated height of 0.330" (8.38mm).

Q: Which part should I select for new designs?

A: Selection depends on regulatory and compliance requirements. If ROHS3 compliance is required, use 805F500E. If RoHS non-compliance is acceptable, either part is suitable based on packaging preference and inventory availability.
