Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 810F500 is determined by strict equivalence across the following parameters:

• Resistance value: 500 Ohms
• Tolerance: ±1%
• Power rating: 10W
• Composition: Wirewound
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C to 275°C
• Housing type: Aluminum
• Mounting feature: Flanges
• Physical dimensions: 0.750" L x 0.812" W (19.05mm x 20.63mm)
• Height - seated (max): 0.400" (10.16mm)
• Lead style: Solder Lugs
• Package type: Axial, Box

The 810F500E maintains complete electrical and mechanical compatibility with the 810F500, differing only in product status (active vs. obsolete) and packaging configuration (tray vs. box).

Parameter Comparison

Engineering Selection Recommendations

The 810F500E is the direct equivalent for the obsolete 810F500. Selection between these parts should be based on the following criteria:

Use 810F500E when:

• New designs or production runs require active product status
• RoHS3 compliance is mandated by application or regulatory requirements
• Tray packaging is compatible with assembly processes

Use 810F500 when:

• Existing inventory is available and product status is not a constraint
• RoHS non-compliance does not conflict with application requirements
• Box packaging is preferred for the specific assembly workflow

Both parts deliver identical electrical performance and mechanical fit within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 810F500E directly replace the 810F500 in existing assemblies? A: Yes. The 810F500E maintains complete electrical and mechanical compatibility. Dimensions, lead style, mounting features, and all electrical parameters are identical.

Q: What is the primary difference between these parts? A: The 810F500E is the active production equivalent of the obsolete 810F500. The 810F500E is ROHS3 compliant, while the 810F500 is RoHS non-compliant. Packaging differs (tray vs. box).

Q: Are there any performance differences? A: No. Both parts share identical resistance value (500 Ohms), tolerance (±1%), power rating (10W), temperature coefficient (±20ppm/°C), and operating temperature range (-55°C to 275°C).

Q: Does packaging affect electrical performance? A: No. Tray and box packaging are logistics configurations only and do not affect component performance or compatibility.

Q: Which part should be specified for new designs? A: The 810F500E should be specified for new designs due to its active product status and ROHS3 compliance.

Q: Are there any dimensional differences between these parts? A: No. Both parts have identical dimensions: 0.750" L x 0.812" W (19.05mm x 20.63mm) with a maximum seated height of 0.400" (10.16mm).
