Ohmite 40F600 Equivalent & Substitute Parts

Part Overview

The Ohmite 40F600 is a 600 Ohm ±1% 10W through-hole resistor with axial wirewound construction, part of the Ohmicone® 40 series. This component is currently active in production and widely used in applications requiring precision power resistors with tight tolerance specifications. Substitute parts are identified when original inventory is unavailable, when packaging requirements differ, or when compliance certifications must be updated to meet current regulatory standards.

Key Parameters

Substitute Part Grouping Explanation

The Ohmite 40F600E is classified as a parametric equivalent to the 40F600. Substitution is valid based on the following criteria:

• Resistance Value: Both parts specify 600 Ohms
• Tolerance: Both maintain ±1% tolerance
• Power Rating: Both are rated at 10W
• Composition: Both utilize wirewound construction
• Package Configuration: Both are axial through-hole components
• Temperature Coefficient: Both specify ±20ppm/°C
• Physical Dimensions: Both share identical dimensions of 0.406" Dia x 1.902" L (10.30mm x 48.30mm)
• Termination Count: Both feature 2 terminations

The primary difference between these parts is packaging format (standard vs. bulk) and RoHS compliance status. The 40F600E offers ROHS3 compliance, whereas the 40F600 is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

Both the 40F600 and 40F600E are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

• 40F600: Select when RoHS non-compliant components are acceptable for the application and standard packaging is required.
• 40F600E: Select when ROHS3 compliance is mandated by design specifications, procurement standards, or end-market regulations. This variant is available in bulk packaging.

Both parts carry identical REACH and ECCN classifications, ensuring equivalent export and supply chain compliance profiles.

Frequently Asked Questions (FAQ)

Q: Are the 40F600 and 40F600E electrically interchangeable? A: Yes. Both parts specify identical resistance (600 Ohms), tolerance (±1%), power rating (10W), temperature coefficient (±20ppm/°C), and composition (wirewound). They are direct electrical equivalents.

Q: Can the 40F600E be used as a direct replacement for the 40F600 in existing designs? A: Yes. The 40F600E maintains identical physical dimensions (0.406" Dia x 1.902" L), axial package configuration, and 2-termination design. No circuit board layout modifications are required.

Q: What is the primary difference between these parts? A: The 40F600E is ROHS3 compliant, while the 40F600 is RoHS non-compliant. Packaging format also differs (bulk vs. standard). All electrical and mechanical parameters are identical.

Q: Which part should be selected for new designs? A: Selection depends on regulatory requirements. If ROHS3 compliance is required, specify the 40F600E. If RoHS compliance is not a design constraint, either part is acceptable based on availability and packaging needs.

Q: Are there any thermal or performance differences between these parts? A: No. Both parts specify identical temperature coefficient (±20ppm/°C) and power rating (10W). Thermal performance and electrical stability are equivalent.
