Key Parameters

Substitute Part Grouping Explanation

The Ohmite 45FR20E qualifies as a parametric equivalent to the 85FR20 based on the following criteria:

• Identical resistance value: 200 mOhms
• Identical tolerance: ±1%
• Identical power rating: 5W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical temperature coefficient: ±90ppm/°C
• Identical physical dimensions: 0.343" Dia x 0.937" L (8.70mm x 23.80mm)
• Identical number of terminations: 2

Both parts are manufactured by Ohmite and maintain active product status. The primary differences are series designation (Acrasil® 80 versus Ohmicone® 40), packaging format (box versus bulk), and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The Ohmite 45FR20E serves as a direct parametric substitute for the 85FR20 across all critical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

RoHS Compliance: The 45FR20E is ROHS3 compliant, while the 85FR20 is RoHS non-compliant. Applications requiring RoHS compliance must use the 45FR20E.

Packaging Format: The 85FR20 is supplied in box packaging, while the 45FR20E is supplied in bulk packaging. Procurement and inventory management practices may influence part selection based on packaging requirements.

Product Availability: Both parts maintain active production status with comparable inventory levels (1051 pieces for 85FR20 and 968 pieces for 45FR20E).

Series Designation: The 85FR20 belongs to the Acrasil® 80 series, while the 45FR20E belongs to the Ohmicone® 40 series. Both series are manufactured by Ohmite and share identical electrical and mechanical characteristics for this resistance value and power rating.

Frequently Asked Questions (FAQ)

Q: Can the 45FR20E replace the 85FR20 in existing designs?

A: Yes. The 45FR20E is electrically and mechanically equivalent to the 85FR20. Both components share identical resistance (200 mOhms), tolerance (±1%), power rating (5W), composition (wirewound), package type (axial), and physical dimensions (0.343" Dia x 0.937" L). Direct substitution is permissible from a functional standpoint.

Q: What is the difference between the Acrasil® 80 and Ohmicone® 40 series?

A: Both series are Ohmite wirewound resistor lines. For the 200 mOhms 5W axial configuration, the electrical and mechanical specifications are identical. Series designation reflects product line organization within Ohmite's portfolio.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance status reflects manufacturing process and material composition restrictions but does not alter the electrical characteristics of the component. Both the 85FR20 and 45FR20E deliver identical electrical performance.

Q: Are the physical dimensions identical?

A: Yes. Both the 85FR20 and 45FR20E measure 0.343" diameter by 0.937" length (8.70mm x 23.80mm). They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: What packaging considerations should I account for?

A: The 85FR20 is supplied in box packaging, while the 45FR20E is supplied in bulk packaging. Box packaging typically includes protective outer cartons suitable for smaller order quantities, while bulk packaging is optimized for larger volume procurement. Select based on your supply chain and inventory management requirements.

Q: Can I use the 45FR20E if my design specifies the 85FR20?

A: Yes, provided your application does not have specific requirements tied to the Acrasil® 80 series designation or RoHS non-compliant status. The 45FR20E is a parametric equivalent and will function identically in the circuit.
