Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 85F2R0 are qualified based on matching the following critical parameters: resistance value (2 Ohms), tolerance (±1%), power rating (5W), composition (wirewound), package type (axial), temperature coefficient (±50ppm/°C), and physical dimensions (0.343" Dia x 0.937" L). All identified substitutes maintain identical electrical and mechanical specifications, ensuring direct functional equivalence in circuit applications. Substitutes differ only in manufacturer series designation and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—85F2R0, 45F2R0E, and 45F2R0—are electrically and mechanically equivalent and suitable for direct substitution in applications requiring a 2 Ohms ±1% 5W axial wirewound resistor.

The 45F2R0E offers ROHS3 compliance, making it the preferred choice for applications subject to RoHS regulations or customer requirements mandating RoHS-compliant components. This part is also available in bulk packaging and maintains the highest inventory level (2000 pieces).

The 85F2R0 and 45F2R0 are RoHS non-compliant and suitable for applications without RoHS requirements. Selection between these two should be based on packaging format preference and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 45F2R0E be used as a direct replacement for 85F2R0? A: Yes. Both parts share identical electrical specifications (2 Ohms, ±1%, 5W), composition (wirewound), temperature coefficient (±50ppm/°C), and physical dimensions (0.343" Dia x 0.937" L). The primary difference is RoHS compliance status and packaging format.

Q: What is the difference between 45F2R0E and 45F2R0? A: Both parts are from the Ohmicone® 40 series with identical electrical and mechanical parameters. The 45F2R0E is supplied in bulk packaging and carries ROHS3 compliance certification, while 45F2R0 does not specify bulk packaging and is RoHS non-compliant.

Q: Are there any dimensional or footprint differences between these parts? A: No. All three parts maintain the same axial package dimensions of 0.343" Dia x 0.937" L (8.70mm x 23.80mm), ensuring identical PCB footprint and mounting compatibility.

Q: Which part should be selected for RoHS-regulated applications? A: The 45F2R0E is ROHS3 compliant and is the appropriate selection for applications subject to RoHS directives or customer RoHS requirements.

Q: Are all parts currently in production? A: Yes. All three parts—85F2R0, 45F2R0E, and 45F2R0—maintain active product status with current inventory availability.
