41F75RE Equivalent & Substitute Parts

Part Overview

The 41F75RE is a 1W 75 Ohms ±1% through-hole resistor manufactured by Ohmite in the Ohmicone® 40 series. This axial wirewound resistor is designed for applications requiring precision resistance with high power dissipation capability. The part is currently active in production with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to supply constraints, design flexibility, or inventory optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 41F75RE is determined by strict equivalence across the following critical parameters:

• Resistance value: 75 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Termination count: 2 (exact match required)

The RS01A75R00FE70 manufactured by Vishay Dale meets all critical electrical parameters and mechanical compatibility requirements, qualifying it as a direct substitute. Both parts operate within overlapping temperature ranges and maintain identical tolerance and power specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 41F75RE and RS01A75R00FE70 are active production parts with current RoHS compliance certifications. Selection between these parts should be based on the following factors:

The 41F75RE operates across a wider temperature range (-55°C to 275°C) compared to the RS01A75R00FE70 (-65°C to 250°C). Applications requiring operation at temperatures above 250°C must use the 41F75RE. Conversely, applications requiring operation below -55°C can utilize either part.

Physical dimensions differ between the two parts. The 41F75RE has a larger diameter (0.126" vs 0.094") and greater length (0.437" vs 0.406"). PCB layout constraints or space-limited applications may favor the smaller RS01A75R00FE70.

The RS01A75R00FE70 includes moisture-resistant construction, providing enhanced environmental protection in humid or corrosive conditions. The 41F75RE carries an unlimited moisture sensitivity rating (MSL 1), indicating no moisture-related restrictions.

Both parts carry identical electrical specifications (75 Ohms ±1%, 1W, ±20ppm/°C) and are suitable for direct substitution in standard applications where temperature and dimensional constraints are not limiting factors.

Frequently Asked Questions (FAQ)

Q: Can the RS01A75R00FE70 replace the 41F75RE in all applications?

A: Direct substitution is valid for applications operating within -55°C to 250°C and where the smaller physical dimensions (0.094" Dia x 0.406" L) are compatible with PCB layout. Applications requiring operation above 250°C must use the 41F75RE.

Q: What is the significance of the moisture-resistant feature on the RS01A75R00FE70?

A: Moisture-resistant construction provides enhanced durability in high-humidity environments or applications with condensation exposure. The 41F75RE's unlimited MSL rating indicates no moisture sensitivity restrictions but does not provide the same environmental protection level.

Q: Are the physical dimensions critical for substitution?

A: Yes. The RS01A75R00FE70 is approximately 0.032" smaller in diameter and 0.031" shorter in length. PCB footprints, mounting hardware, and thermal management designs must accommodate these dimensional differences.

Q: Do both parts meet current regulatory compliance?

A: Yes. The 41F75RE is RoHS Compliant, and the RS01A75R00FE70 is ROHS3 Compliant. Both meet current environmental and hazardous substance restrictions.

Q: What packaging formats are available?

A: The 41F75RE is supplied in Box packaging, while the RS01A75R00FE70 is supplied in Cut Tape (CT) format. Packaging selection depends on assembly process requirements and inventory management preferences.
