Substitute Part Grouping Explanation

Substitution for the Ohmite 43F900 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 900 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Package type: Axial
• Physical dimensions: 0.220" Dia x 0.594" L (5.60mm x 15.10mm)
• Temperature coefficient: ±20ppm/°C
• Termination count: 2

The identified substitute maintains identical electrical specifications and physical form factor, with the primary distinction being compliance status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The Ohmite 43F900E serves as a direct parametric equivalent to the 43F900, with identical electrical and mechanical specifications. The primary distinction is regulatory compliance: the 43F900E is RoHS Compliant, whereas the 43F900 is RoHS non-compliant. Selection between these parts should be based on application requirements and procurement policies regarding RoHS compliance. The 43F900E offers higher inventory availability at 1190 pieces compared to 727 pieces for the 43F900. Both components maintain active product status and are suitable for applications requiring 900 Ohms ±1% 3W axial wirewound resistors.

Frequently Asked Questions (FAQ)

Q: Are the 43F900 and 43F900E electrically identical?
