Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 805F75R is determined by strict equivalence across the following critical parameters:

• Resistance value: 75 Ohms
• Tolerance: ±1%
• Power rating: 5W
• Composition: Wirewound
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C to 275°C
• Mounting feature: Flanges
• Lead style: Solder Lugs
• Physical dimensions: 0.600" L x 0.646" W (15.24mm x 16.41mm)
• Height - Seated (Max): 0.330" (8.38mm)
• Housing type: Aluminum
• Package type: Axial, Box

The 805F75RE meets all these criteria and is classified as a direct equivalent. The primary distinction is packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The 805F75RE is the direct equivalent replacement for the obsolete 805F75R. Both components are manufactured by Ohmite within the Metal-Mite®89 series and share identical electrical and mechanical specifications. The 805F75RE offers the advantage of active product status, ensuring continued availability and supply chain reliability.

The 805F75RE carries ROHS3 compliance certification, whereas the 805F75R is non-compliant. For applications subject to RoHS regulatory requirements, the 805F75RE is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either component provides equivalent electrical performance.

The packaging difference (standard versus tray) does not affect component functionality or electrical characteristics and is a logistics consideration only.

Frequently Asked Questions (FAQ)

Q: Can the 805F75RE be used as a direct replacement for the 805F75R?

A: Yes. The 805F75RE is electrically and mechanically identical to the 805F75R. All critical parameters—resistance value, tolerance, power rating, temperature coefficient, operating temperature range, dimensions, and mounting features—are equivalent.

Q: What is the primary reason to transition from 805F75R to 805F75RE?

A: The 805F75R is classified as obsolete. The 805F75RE is the active equivalent, ensuring long-term availability and supply chain continuity.

Q: Does the packaging format difference affect component performance?

A: No. The packaging format (standard versus tray) is a logistics and handling consideration only. It does not affect electrical performance, mechanical fit, or thermal characteristics.

Q: Are there compliance differences between these parts?

A: Yes. The 805F75RE is ROHS3 compliant, while the 805F75R is RoHS non-compliant. For applications requiring RoHS certification, the 805F75RE is the required selection.

Q: Will the 805F75RE fit in existing PCB designs using the 805F75R?

A: Yes. Physical dimensions, mounting features, lead style, and solder lug configuration are identical. No PCB redesign is required.

Q: Are there any electrical performance differences?

A: No. Resistance value, tolerance, power rating, temperature coefficient, and operating temperature range are identical between both components.
