41F30RE Equivalent & Substitute Parts

Part Overview

The 41F30RE is a 30 Ohm ±1% 1W axial wirewound through-hole resistor manufactured by Ohmite, part of the Ohmicone® 40 series. This component is designed for applications requiring precision resistance with wirewound construction and is currently in active production status. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the 41F30RE is permissible with components matching the following critical parameters:

• Resistance value: 30 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package configuration: Axial with 2 terminations
• Temperature coefficient: ±20ppm/°C
• RoHS3 compliance

The RS01A30R00FE70 from Vishay Dale meets all substitution criteria. Both components share identical electrical specifications and are functionally equivalent for circuit applications. Physical dimensions vary slightly, but both conform to standard axial package geometry suitable for through-hole PCB mounting.

Parameter Comparison

Engineering Selection Recommendations

Both the 41F30RE and RS01A30R00FE70 are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Availability and lead time requirements
• Packaging format preference (Bulk versus Cut Tape)
• Environmental operating conditions (the RS01A30R00FE70 specifies -65°C ~ 250°C operating range and includes moisture-resistant construction)
• Supply chain sourcing strategy

Electrical performance is equivalent across both components for standard circuit applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the RS01A30R00FE70 directly replace the 41F30RE in existing designs?

A: Yes. Both components share identical resistance value (30 Ohms), tolerance (±1%), power rating (1W), temperature coefficient (±20ppm/°C), and axial package configuration. Electrical substitution is direct.

Q: Are there physical dimension differences between these parts?

A: Yes. The 41F30RE measures 0.126" Dia x 0.437" L (3.20mm x 11.10mm), while the RS01A30R00FE70 measures 0.094" Dia x 0.406" L (2.39mm x 10.31mm). Both conform to standard axial through-hole geometry and are compatible with typical PCB layouts designed for 1W axial resistors.

Q: What is the significance of the moisture-resistant feature on the RS01A30R00FE70?

A: The moisture-resistant construction on the RS01A30R00FE70 provides enhanced protection in humid or corrosive environments. This feature does not affect electrical compatibility but may offer improved reliability in specific application environments.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 41F30RE and RS01A30R00FE70 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0080.

Q: What packaging formats are available?

A: The 41F30RE is supplied in Bulk packaging, while the RS01A30R00FE70 is supplied in Cut Tape (CT) format. Selection depends on assembly process requirements and inventory management preferences.
