Key Parameters

Substitute Part Grouping Explanation

Substitution for the Ohmite 33J1R0 is determined by strict equivalence across the following critical parameters: resistance value (1 Ohms), tolerance (±5%), power rating (3W), composition (wirewound), package type (axial), and physical dimensions (0.217" Dia x 0.594" L). The substitute part 33J1R0E maintains identical electrical and mechanical specifications, with the primary distinction being packaging format (bulk versus standard) and RoHS compliance status. Both parts are manufactured by Ohmite and belong to the High Energy Wirewound series, ensuring functional interchangeability in circuit applications where these parameters are required.

Parameter Comparison

Engineering Selection Recommendations

The Ohmite 33J1R0E serves as a direct functional substitute for the 33J1R0, with identical electrical performance and mechanical compatibility. Selection between these parts should be based on compliance requirements and packaging needs. The 33J1R0E offers ROHS3 compliance, making it suitable for applications subject to RoHS regulations. The 33J1R0 remains appropriate for applications without RoHS compliance mandates. Both parts maintain active production status and adequate inventory levels. Packaging format (standard versus bulk) should be evaluated based on procurement volume and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the 33J1R0E replace the 33J1R0 in existing designs? A: Yes. Both parts are electrically and mechanically identical, with resistance of 1 Ohms ±5%, 3W power rating, wirewound composition, and axial package dimensions of 0.217" Dia x 0.594" L. Direct substitution is valid for circuit applications.

Q: What is the difference between the 33J1R0 and 33J1R0E? A: The primary differences are packaging format (standard versus bulk) and RoHS compliance status. The 33J1R0E is ROHS3 compliant, while the 33J1R0 is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Which part should be selected for RoHS-regulated applications? A: The 33J1R0E is ROHS3 compliant and is the appropriate selection for applications subject to RoHS directives and regulations.

Q: Are the physical dimensions identical between both parts? A: Yes. Both the 33J1R0 and 33J1R0E share identical dimensions of 0.217" Dia x 0.594" L (5.50mm x 15.10mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What packaging options are available? A: The 33J1R0 is available in standard packaging, while the 33J1R0E is supplied in bulk packaging format. Selection depends on procurement volume and supply chain logistics.
