Substitute Part Grouping Explanation

The Ohmite 40F10R qualifies as a direct substitute for the 80F10R based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Resistance value: 10 Ohms (identical)
• Tolerance: ±1% (identical)
• Power rating: 10W (identical)
• Composition: Wirewound (identical)
• Package: Axial through-hole (identical)
• Temperature coefficient: ±20ppm/°C (identical)
• Termination count: 2 (identical)
• RoHS status: Non-compliant (identical)

The 40F10R belongs to the Ohmicone® 40 series, while the 80F10R belongs to the Acrasil® 80 series. Both series employ identical electrical specifications and axial packaging, with only minor dimensional variation in length (48.30mm vs. 46.80mm).

Parameter Comparison

Engineering Selection Recommendations

Both the 80F10R and 40F10R maintain active product status with current manufacturer support. Selection between these parts should be based on:

• PCB layout constraints: The 40F10R is 2.5mm longer than the 80F10R. Verify available board space before substitution.
• Inventory availability: The 40F10R currently has 793 units in stock compared to 664 units for the 80F10R.
• Compliance requirements: Both parts carry identical RoHS non-compliant status and are subject to the same regulatory classifications (ECCN: EAR99, HTSUS: 8533.21.0080).
• Packaging format: The 80F10R is supplied in standard packaging, while the 40F10R is supplied in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the 40F10R replace the 80F10R in existing designs?

A: Yes, provided PCB layout accommodates the 2.5mm length difference. All electrical parameters, power rating, tolerance, and temperature coefficient are identical.

Q: What is the primary difference between these two parts?

A: The parts belong to different Ohmite series (Acrasil® 80 vs. Ohmicone® 40) and differ in axial length by 2.5mm. Electrical specifications are identical.

Q: Are there any compliance or regulatory differences?

A: No. Both parts share identical RoHS status (non-compliant), ECCN classification (EAR99), and HTSUS code (8533.21.0080).

Q: Which part should I select for new designs?

A: Either part is acceptable for new designs. Selection depends on PCB space availability and current inventory status. Verify dimensional fit in your specific application.

Q: Is the temperature coefficient the same for both parts?

A: Yes. Both the 80F10R and 40F10R have a temperature coefficient of ±20ppm/°C.
