Ohmite 40J600 600 Ohm 10W Axial Wirewound Resistor Equivalent & Substitute Parts

Part Overview

The Ohmite 40J600 is a 600 Ohm, ±5% tolerance, 10W through-hole axial wirewound resistor from the Ohmicone® 40 series. This component is actively manufactured and widely used in applications requiring precision power dissipation in compact form factors. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part number becomes unavailable or when alternative packaging configurations are required.

Substitute Part Grouping Explanation

Substitution of the Ohmite 40J600 is determined by electrical and mechanical parameter equivalence. The substitute part must maintain identical specifications across the following critical parameters: resistance value (600 Ohms), tolerance (±5%), power rating (10W), composition (wirewound), package configuration (axial), temperature coefficient (±20ppm/°C), and physical dimensions (0.406" Dia x 1.902" L). The 40J600E variant meets all these requirements and is classified as a parametric equivalent. The primary distinction between the main part and its substitute is packaging configuration (tape and reel versus bulk) and RoHS compliance status, neither of which affects electrical or mechanical interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 40J600 and 40J600E are active products manufactured by Ohmite and are electrically and mechanically identical. Selection between these parts should be based on regulatory and compliance requirements specific to the end application. The 40J600E variant carries ROHS3 compliance certification, making it the appropriate choice for applications subject to RoHS directives or customer specifications requiring RoHS-compliant components. The 40J600 remains suitable for applications without RoHS compliance mandates. Packaging configuration differs between the two parts (bulk versus tape and reel), which may influence procurement and assembly processes but does not affect circuit performance or interchangeability.

Frequently Asked Questions (FAQ)

Q: Are the 40J600 and 40J600E electrically interchangeable? A: Yes. Both parts are identical in resistance value (600 Ohms), tolerance (±5%), power rating (10W), temperature coefficient (±20ppm/°C), and all other electrical specifications. They are direct substitutes in circuit applications.

Q: What is the difference between the 40J600 and 40J600E? A: The primary differences are packaging configuration and RoHS compliance status. The 40J600E is supplied in bulk packaging and carries ROHS3 compliance certification, while the 40J600 is non-compliant with RoHS directives. Electrical and mechanical specifications are identical.

Q: Can I use the 40J600E as a replacement for the 40J600 in my design? A: Yes, provided your application does not have specific requirements that exclude RoHS-compliant components. The 40J600E is a direct parametric equivalent and will function identically in all circuit configurations where the 40J600 is specified.

Q: Are the physical dimensions identical between these parts? A: Yes. Both the 40J600 and 40J600E share identical axial package dimensions of 0.406" diameter by 1.902" length (10.30mm x 48.30mm), ensuring identical PCB footprint and mounting compatibility.

Q: Which part should I select for new designs? A: Selection should be based on regulatory requirements. For applications requiring RoHS compliance, specify the 40J600E. For applications without RoHS mandates, either part is acceptable based on availability and procurement preferences.
