Substitute Part Grouping Explanation

Substitution eligibility for the 41F7R5 is determined by strict equivalence across the following critical parameters:

• Resistance value: 7.5 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±50ppm/°C
• Physical dimensions: 0.126" Dia x 0.437" L (3.20mm x 11.10mm)
• Number of terminations: 2

The identified substitute part 41F7R5E matches all electrical and mechanical specifications, with the primary distinction being packaging format and compliance certification status.

Parameter Comparison

Engineering Selection Recommendations

Both the 41F7R5 and 41F7R5E are active products from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

The 41F7R5E offers ROHS3 compliance, making it suitable for applications subject to RoHS regulations. The 41F7R5 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Packaging format differs between the two parts: the 41F7R5 uses standard packaging while the 41F7R5E is supplied in bulk format. Bulk packaging may be advantageous for high-volume production runs.

Both parts carry identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications, indicating equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 41F7R5E be used as a direct replacement for the 41F7R5?
