Equivalent & Substitute Parts for Ohmite 41FR13

Part Overview

The Ohmite 41FR13 is a 130 mOhms ±1% 1W through-hole resistor with axial wirewound construction, part of the Ohmicone® 40 series. This component is actively manufactured and maintained in stock inventory. Substitute parts are identified when original stock becomes unavailable, when procurement lead times require alternatives, or when design flexibility permits equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 41FR13 is determined by matching 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)
• Termination Count: 2 (exact match required)

The Vishay Dale ALSR01R1300FE12 meets all substitution criteria. Both components are active products with identical electrical specifications and compatible axial package configurations. Physical dimensions vary slightly, but both conform to standard axial resistor form factors suitable for through-hole PCB mounting.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 41FR13 and Vishay Dale ALSR01R1300FE12 are active products with identical core electrical specifications. Selection between these components should be based on the following factors:

Ohmite 41FR13: Select when original part specification is required or when RoHS non-compliance is acceptable for the application.

Vishay Dale ALSR01R1300FE12: Select when ROHS3 compliance is required, when moisture-resistant construction is beneficial, or when the specified operating temperature range of -65°C to 250°C is needed. The slightly smaller physical dimensions may provide layout advantages in space-constrained applications.

Both components are suitable for direct substitution in through-hole PCB designs where the axial resistor form factor is employed.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Dale ALSR01R1300FE12 be used as a direct replacement for the Ohmite 41FR13?

A: Yes. Both components share identical resistance value (130 mOhms), tolerance (±1%), power rating (1W), composition (wirewound), and axial package configuration. The electrical performance is equivalent.

Q: What are the physical dimension differences between these parts?

A: The Ohmite 41FR13 measures 0.126" diameter by 0.437" length. The Vishay Dale ALSR01R1300FE12 measures 0.110" diameter by 0.406" length. Both are standard axial resistor form factors. Verify PCB layout clearances if space is constrained.

Q: Does the Vishay Dale part offer any additional benefits?

A: The ALSR01R1300FE12 includes moisture-resistant construction and is ROHS3 compliant. It also specifies an operating temperature range of -65°C to 250°C, whereas the 41FR13 does not provide this specification.

Q: Are there any compliance considerations for substitution?

A: The Ohmite 41FR13 is RoHS non-compliant, while the Vishay Dale ALSR01R1300FE12 is ROHS3 compliant. If RoHS compliance is required for your application, the Vishay Dale part is the appropriate selection.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the PCB layout accommodates the slight dimensional differences. Both components use standard axial lead configurations and are suitable for through-hole mounting.
