Ohmite 40F220 Equivalent & Substitute Parts

Part Overview

The Ohmite 40F220 is a 220 Ohm, ±1% tolerance, 10W axial wirewound through-hole resistor from the Ohmicone® 40 series. This component is designed for applications requiring precision resistance with high power dissipation capability in a compact axial package. The part is currently active in production with 849 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to availability constraints, packaging preferences, or compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

The 40F220E is classified as a parametric equivalent to the 40F220. Substitution eligibility is determined by matching the following critical parameters:

• Resistance value: 220 Ohms
• Tolerance: ±1%
• Power rating: 10W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.406" Dia x 1.902" L (10.30mm x 48.30mm)
• Number of terminations: 2

The 40F220E meets all electrical and mechanical requirements for direct substitution with the primary distinction being packaging format (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 40F220 and 40F220E are active production components from Ohmite's Ohmicone® 40 series with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

40F220: Select this part number when RoHS non-compliant components are acceptable for the application and standard packaging is required.

40F220E: Select this part number when ROHS3 compliance is mandated by design requirements or regulatory constraints. The bulk packaging format may be advantageous for high-volume procurement scenarios.

Both parts carry the same ECCN (EAR99) and HTSUS classification, ensuring equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 40F220E be used as a direct replacement for the 40F220?

A: Yes. The 40F220E is electrically and mechanically identical to the 40F220. All critical parameters—resistance value, tolerance, power rating, temperature coefficient, and physical dimensions—are matched. The primary difference is RoHS compliance status and packaging format.

Q: What is the difference between the 40F220 and 40F220E?

A: The 40F220E is ROHS3 compliant, while the 40F220 is RoHS non-compliant. The 40F220E is supplied in bulk packaging. All other specifications are identical.

Q: Are there any performance differences between these parts?

A: No. Both parts are wirewound resistors with identical resistance values, tolerances, power ratings, temperature coefficients, and physical dimensions. Performance in circuit applications will be equivalent.

Q: Which part should I specify for new designs?

A: Specify the 40F220E for new designs requiring ROHS3 compliance. If RoHS compliance is not a requirement, either part may be used based on availability and packaging preferences.

Q: Do these parts have the same footprint and mounting characteristics?

A: Yes. Both parts are axial through-hole resistors with identical dimensions (0.406" Dia x 1.902" L) and two terminations, ensuring identical PCB footprint and mounting compatibility.
