45F800E Equivalent & Substitute Parts

Part Overview

The 45F800E is a 5W wirewound axial resistor with 800 Ohms resistance and ±1% tolerance, manufactured by Ohmite in the Ohmicone® 40 series. This component is actively produced and RoHS compliant, designed for through-hole applications requiring precision resistive elements in industrial and commercial electronics. Equivalent and substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across alternative manufacturers or packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 45F800E is determined by strict equivalence in the following parameters: resistance value (800 Ohms), tolerance (±1%), power rating (5W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), and physical dimensions (0.343" Dia x 0.937" L). Packaging format (box versus bulk versus cut tape) does not affect electrical or mechanical compatibility. Compliance certifications and operating temperature ranges are secondary selection criteria when multiple equivalent parts are available.

Parameter Comparison

Engineering Selection Recommendations

The 45F800E and 45F800 are electrically and mechanically identical, differing only in packaging format and RoHS compliance status. Selection between these two Ohmite variants depends on regulatory requirements and procurement logistics. The 45F800E is suitable for applications requiring RoHS compliance; the 45F800 is available for non-compliant applications.

The RS005800R0FE73 from Vishay Dale meets all core electrical specifications and is ROHS3 compliant. Physical dimensions differ slightly (0.312" Dia x 0.875" L versus 0.343" Dia x 0.937" L), and operating temperature range is -65°C ~ 250°C versus -55°C ~ 275°C. This part is suitable for applications where the dimensional and temperature variations are acceptable. The RS005800R0FE73 includes moisture-resistant features not specified in the Ohmite variants.

Frequently Asked Questions (FAQ)

Q: Can 45F800 (bulk packaging) be used in place of 45F800E (box packaging)? A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Selection depends on RoHS compliance requirements: 45F800E is RoHS compliant; 45F800 is not.

Q: Is RS005800R0FE73 a direct substitute for 45F800E? A: RS005800R0FE73 meets all core electrical specifications (800 Ohms, ±1%, 5W, wirewound, axial). Physical dimensions are slightly smaller (0.312" Dia x 0.875" L versus 0.343" Dia x 0.937" L), and operating temperature range is -65°C ~ 250°C versus -55°C ~ 275°C. Verify that dimensional and temperature differences are acceptable for your application before substitution.

Q: What parameters must remain identical for substitution? A: Resistance (800 Ohms), tolerance (±1%), power rating (5W), composition (wirewound), package type (axial), and temperature coefficient (±20ppm/°C) must be identical. Packaging format, RoHS status, and operating temperature range are secondary considerations.

Q: Does packaging format affect electrical performance? A: No. Box, bulk, and cut tape packaging formats contain identical components and do not affect electrical or mechanical performance. Selection is based on procurement and assembly requirements.

Q: Are there compliance differences between these parts? A: Yes. 45F800E is RoHS compliant. 45F800 is RoHS non-compliant. RS005800R0FE73 is ROHS3 compliant. Select based on your application's regulatory requirements.
