Substitute Part Grouping Explanation

Substitution for the Ohmite 42J600 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 600 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Wirewound
• Temperature coefficient: ±20ppm/°C
• Package configuration: Axial through-hole
• Physical dimensions: 0.220" Dia x 0.406" L (5.60mm x 10.30mm)
• Number of terminations: 2

The identified substitute part maintains identical electrical specifications and physical form factor, with the primary distinction being packaging configuration and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 42J600 and 42J600E are functionally equivalent and electrically interchangeable. Selection between these part numbers should be based on the following criteria:

42J600: Select this part number when standard packaging is required and RoHS non-compliant components are acceptable for the application.

42J600E: Select this part number when ROHS3 compliance is mandated by design specifications, regulatory requirements, or customer procurement policies. This variant is supplied in bulk packaging configuration.

Both parts maintain identical electrical performance, physical dimensions, and thermal characteristics. The choice between them is driven by compliance requirements and packaging logistics rather than technical performance.

Frequently Asked Questions (FAQ)

Q: Are the 42J600 and 42J600E electrically interchangeable?

A: Yes. Both parts are identical in resistance value (600 Ohms), tolerance (±5%), power rating (2W), temperature coefficient (±20ppm/°C), and composition (wirewound). They are direct electrical equivalents.

Q: What is the difference between these part numbers?

A: The primary differences are packaging configuration (standard versus bulk) and RoHS compliance status. The 42J600 is RoHS non-compliant, while the 42J600E is ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Can I use 42J600E as a direct replacement for 42J600 in my design?

A: Yes, provided that ROHS3 compliance does not conflict with your application requirements. The physical dimensions, electrical characteristics, and form factor are identical, enabling direct substitution in PCB layouts and circuit designs.

Q: Are there any physical dimension differences between these parts?

A: No. Both parts share identical physical dimensions of 0.220" Dia x 0.406" L (5.60mm x 10.30mm), ensuring compatibility with existing PCB footprints and mechanical assemblies.

Q: What does bulk packaging mean for the 42J600E?

A: Bulk packaging indicates that the 42J600E is supplied in larger quantities without individual component packaging, typically used for high-volume manufacturing operations. Standard packaging (42J600) includes individual component wrapping suitable for lower-volume applications.

Q: Which part should I specify for new designs?

A: Specify based on your compliance requirements. If ROHS3 compliance is required, use 42J600E. If RoHS compliance is not a design constraint, either part is acceptable. Both are Active products in current production.
