Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 80F1R0 are qualified based on the following critical parameters:

• Resistance value: 1 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Termination count: 2 (exact match required)

The Vishay Dale RS0101R000FS73 meets all critical electrical and mechanical parameters, qualifying it as a direct substitute. Physical dimensions vary slightly within acceptable tolerances for axial component mounting.

Parameter Comparison

Engineering Selection Recommendations

Both the 80F1R0 and RS0101R000FS73 are active production components with identical core electrical specifications. Selection between these parts should be based on:

• Packaging format requirements: The 80F1R0 is supplied in box packaging, while the RS0101R000FS73 is supplied in tape and reel format. Choose based on assembly process compatibility.
• Environmental performance: The RS0101R000FS73 includes moisture-resistant construction and a specified operating temperature range of -65°C to 250°C, providing additional environmental protection.
• Supply availability: The RS0101R000FS73 has higher inventory availability (1317 pieces versus 762 pieces).
• Compliance requirements: Both parts maintain identical RoHS non-compliant status and ECCN classification (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the RS0101R000FS73 directly replace the 80F1R0 in existing designs?

A: Yes. Both components share identical electrical specifications (1 Ohms, ±1%, 10W, ±50ppm/°C) and axial through-hole packaging. Physical dimensions differ slightly (0.375" Dia x 1.780" L versus 0.406" Dia x 1.843" L), but both are compatible with standard axial component mounting.

Q: What is the difference in packaging between these parts?

A: The 80F1R0 is supplied in box packaging for manual handling and small-quantity applications. The RS0101R000FS73 is supplied in tape and reel format, optimized for automated assembly processes.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS non-compliant and classified as EAR99 for export control purposes. The RS0101R000FS73 is REACH Affected, while the 80F1R0 status is not specified.

Q: Which part should be selected for high-temperature applications?

A: The RS0101R000FS73 specifies an operating temperature range of -65°C to 250°C. The 80F1R0 does not provide an operating temperature specification. For applications requiring defined temperature performance, the RS0101R000FS73 is the appropriate selection.

Q: Does the moisture-resistant feature of the RS0101R000FS73 affect substitution compatibility?

A: No. Moisture resistance is an additional feature that does not impact electrical or mechanical compatibility. It provides enhanced environmental protection without affecting circuit performance.
