Substitute Part Grouping Explanation

Substitute parts for the 41F27R are identified based on electrical parameter equivalence and mechanical compatibility. The primary substitution criterion is functional equivalence across the following parameters:

• Resistance value: 27 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Temperature coefficient: ±20ppm/°C
• Package configuration: Axial
• Physical dimensions: 0.126" Dia x 0.437" L (3.20mm x 11.10mm)
• Number of terminations: 2

The identified substitute maintains all electrical specifications and physical form factor, with variation only in packaging configuration and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 41F27R and 41F27RE are electrically and mechanically equivalent components from the same manufacturer and series. Selection between these parts should be based on the following criteria:

RoHS Compliance Requirements: The 41F27RE is ROHS3 compliant, while the 41F27R is RoHS non-compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must use the 41F27RE.

Packaging Configuration: The 41F27R is supplied in standard packaging, while the 41F27RE is supplied in bulk packaging. Packaging selection depends on procurement volume and handling requirements.

Availability: Both parts are active in production with adequate inventory. The 41F27RE has slightly higher stock availability (1163 units versus 1048 units).

Export Classification: Both parts carry the same ECCN classification (EAR99) and HTSUS code (8533.21.0080), indicating equivalent regulatory treatment for export purposes.

Frequently Asked Questions (FAQ)

Q: Are the 41F27R and 41F27RE electrically identical?

A: Yes. Both components have identical electrical specifications: 27 Ohm resistance, ±1% tolerance, 1W power rating, wirewound composition, and ±20ppm/°C temperature coefficient.

Q: Can the 41F27RE be used as a direct replacement for the 41F27R?

A: Yes, from an electrical and mechanical standpoint. The 41F27RE maintains identical resistance value, tolerance, power rating, physical dimensions, and axial package configuration. The primary difference is RoHS compliance status and packaging format.

Q: What is the difference between standard and bulk packaging?

A: Standard packaging (41F27R) and bulk packaging (41F27RE) refer to the quantity and presentation format of components during shipment. Both contain the same component; the difference is in how units are packaged for delivery.

Q: Which part should I specify for RoHS-compliant applications?

A: The 41F27RE is ROHS3 compliant and must be specified for applications requiring RoHS compliance. The 41F27R is RoHS non-compliant and is not suitable for such applications.

Q: Are the physical dimensions identical?

A: Yes. Both the 41F27R and 41F27RE have identical dimensions of 0.126" diameter by 0.437" length (3.20mm x 11.10mm), ensuring identical PCB footprint and mounting compatibility.

Q: Do both parts have the same export classification?

A: Yes. Both components are classified as EAR99 and carry the same HTSUS code (8533.21.0080), indicating identical regulatory treatment for export purposes.
