Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 41FR13E is determined by the following critical parameters:

• Resistance value: 130 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Number of terminations: 2 (exact match required)
• Compliance: ROHS3 Compliant (minimum requirement)

The substitute part ALSR01R1300FE12 from Vishay Dale meets all critical electrical and mechanical parameters. Physical dimensions vary slightly, but both components are classified as axial through-hole resistors suitable for standard PCB mounting applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 41FR13E and ALSR01R1300FE12 are active products with ROHS3 compliance and identical core electrical specifications. Selection between these components should be based on:

• Physical space constraints: The ALSR01R1300FE12 has a smaller diameter (0.110" vs 0.126") and shorter length (0.406" vs 0.437"), making it suitable for compact PCB layouts.
• Environmental conditions: The ALSR01R1300FE12 includes moisture-resistant construction, providing enhanced protection in humid or corrosive environments.
• Supply chain availability: Both components maintain active inventory status and are suitable for direct substitution in new designs or component replacement scenarios.
• Thermal performance: The ALSR01R1300FE12 specifies an operating temperature range of -65°C to 250°C, providing extended thermal operating margins compared to the 41FR13E.

Frequently Asked Questions (FAQ)

Q: Can ALSR01R1300FE12 be used as a direct replacement for 41FR13E?

A: Yes. Both components share identical resistance (130 mOhms), tolerance (±1%), power rating (1W), composition (wirewound), package type (axial), and compliance status (ROHS3). Physical dimensions differ slightly, but both are standard axial through-hole components compatible with conventional PCB mounting.

Q: What are the physical dimension differences?

A: The 41FR13E measures 0.126" diameter × 0.437" length (3.20mm × 11.10mm). The ALSR01R1300FE12 measures 0.110" diameter × 0.406" length (2.79mm × 10.31mm). The substitute is smaller in both dimensions, which may be advantageous in space-constrained applications but requires verification of PCB layout compatibility.

Q: Does the moisture-resistant feature of ALSR01R1300FE12 affect electrical performance?

A: No. Moisture resistance is a construction feature that enhances environmental durability without altering the core electrical characteristics. Both components maintain ±1% tolerance and 1W power rating.

Q: Are both parts suitable for high-temperature applications?

A: The ALSR01R1300FE12 specifies an operating range of -65°C to 250°C. The 41FR13E does not specify an operating temperature range in the provided data. For applications requiring confirmed high-temperature performance, the ALSR01R1300FE12 provides documented thermal specifications.

Q: What is the significance of the temperature coefficient specification?

A: The 41FR13E specifies a temperature coefficient of ±90ppm/°C. This indicates the resistance value will change by approximately 90 parts per million for each degree Celsius change in operating temperature. The ALSR01R1300FE12 does not provide a temperature coefficient specification in the available data.
