Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 41F35R are qualified based on the following critical parameters:

• Resistance Value: 35 Ohms (exact match required)
• Tolerance: ±1% (equivalent or tighter tolerance acceptable)
• Power Rating: 1W (equal or greater rating acceptable)
• Composition: Wirewound (maintains electrical characteristics)
• Package: Axial (mechanical and electrical compatibility)
• Termination Count: 2 (standard through-hole configuration)

The Vishay Dale ALSR0135R00FE12 meets all substitution criteria with identical electrical specifications and compatible mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the 41F35R and ALSR0135R00FE12 are active production components with identical core electrical specifications (35 Ohms, ±1%, 1W, wirewound, axial package). Selection between these parts should be based on the following factors:

RoHS Compliance: The ALSR0135R00FE12 is ROHS3 compliant, while the 41F35R is RoHS non-compliant. Applications subject to RoHS regulations must use the Vishay Dale substitute.

Temperature Coefficient: The 41F35R exhibits ±20ppm/°C while the ALSR0135R00FE12 exhibits ±30ppm/°C. Applications requiring tighter temperature stability should retain the Ohmite part.

Physical Dimensions: The ALSR0135R00FE12 is slightly smaller (0.110" Dia x 0.406" L versus 0.126" Dia x 0.437" L). PCB layout constraints may favor the Vishay Dale component.

Moisture Resistance: The ALSR0135R00FE12 includes moisture-resistant construction with MSL 1 rating, providing enhanced environmental protection compared to the standard 41F35R.

Frequently Asked Questions (FAQ)

Q: Can the ALSR0135R00FE12 directly replace the 41F35R in all applications?

A: The ALSR0135R00FE12 is electrically and mechanically compatible for most applications. However, verify RoHS compliance requirements for your end application. The slightly higher temperature coefficient (±30ppm/°C versus ±20ppm/°C) may affect precision circuits requiring tight temperature stability.

Q: What is the difference in physical size between these parts?

A: The 41F35R measures 0.126" diameter by 0.437" length, while the ALSR0135R00FE12 measures 0.110" diameter by 0.406" length. Both are axial package configurations with identical lead spacing suitable for standard through-hole PCB layouts. Verify PCB footprint compatibility before substitution.

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

A: The ALSR0135R00FE12 specifies an operating temperature range of -65°C to 250°C. The 41F35R does not provide an explicit operating temperature range in available documentation. For applications exceeding standard temperature ranges, confirm thermal specifications with the component manufacturer.

Q: Which part should I select for moisture-sensitive environments?

A: The ALSR0135R00FE12 includes moisture-resistant construction and carries an MSL rating of 1 (Unlimited), making it suitable for high-humidity or outdoor applications. The 41F35R does not specify moisture resistance features.

Q: Are there any compliance differences between these parts?

A: The ALSR0135R00FE12 is ROHS3 compliant and carries REACH Unaffected status. The 41F35R is RoHS non-compliant. For applications subject to RoHS directives or equivalent environmental regulations, the Vishay Dale part is required.
