Ohmite 30J33R Equivalent & Substitute Parts

Part Overview

The Ohmite 30J33R is a 33 Ohm, 5% tolerance, 10W axial wirewound through-hole resistor from the High Energy Wirewound series. This component is classified as Active product status and is suitable for applications requiring precision power dissipation in compact form factors. Equivalent and substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across the same product category, enabling procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the 30J33R is determined by strict equivalence across the following parameters: resistance value (33 Ohms), tolerance band (±5%), power dissipation capability (10W), composition type (Wirewound), package configuration (Axial), and physical dimensions (0.406" Dia x 1.843" L). The substitute part 30J33RE meets all these criteria, differing only in packaging format (Bulk versus standard packaging) and compliance certifications, which do not affect electrical or mechanical interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The 30J33RE serves as a direct parametric equivalent to the 30J33R, with all critical electrical and mechanical specifications maintained. The primary distinction is RoHS compliance status: the 30J33R is RoHS non-compliant, while the 30J33RE is ROHS3 compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99). The 30J33RE is available in Bulk packaging, whereas the 30J33R uses standard packaging; this distinction affects procurement and inventory management but not circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the 30J33RE replace the 30J33R in existing designs? A: Yes. The 30J33RE is electrically and mechanically identical to the 30J33R. All critical parameters—resistance value, tolerance, power rating, composition, package type, and physical dimensions—are equivalent. Substitution is valid for circuit applications.

Q: What is the difference between the 30J33R and 30J33RE? A: The parts differ in two aspects: packaging format (standard versus Bulk) and RoHS compliance status (non-compliant versus ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Does RoHS compliance affect circuit performance? A: No. RoHS compliance is a regulatory and material composition classification that does not alter electrical performance, power dissipation capability, or mechanical fit. Selection should be based on application regulatory requirements.

Q: Are the physical dimensions identical between these parts? A: Yes. Both the 30J33R and 30J33RE have identical dimensions of 0.406" Dia x 1.843" L (10.30mm x 46.80mm), ensuring identical PCB footprint and mounting compatibility.

Q: What does "Bulk" packaging mean for the 30J33RE? A: Bulk packaging indicates the part is supplied in loose form without individual packaging, typically used for high-volume procurement. This affects handling and inventory management but not the component itself.
