Ohmite 30J2R0 Equivalent & Substitute Parts

Part Overview

The Ohmite 30J2R0 is a 2 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 designed for applications requiring precision power dissipation in compact form factors. Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (axial package, physical dimensions, termination count).

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 30J2R0 are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 2 Ohms
• Tolerance: ±5%
• Power dissipation capability: 10W

Mechanical Parameters (Critical):

• Package configuration: Axial
• Physical dimensions: 0.406" Dia x 1.843" L (10.30mm x 46.80mm)
• Termination count: 2 leads
• Composition: Wirewound

Manufacturing Parameters:

• Manufacturer: Ohmite
• Series: High Energy Wirewound
• Product Status: Active

Parts meeting all these criteria are classified as direct substitutes and are electrically and mechanically interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The 30J2R0E is a direct electrical and mechanical substitute for the 30J2R0. Both parts are manufactured by Ohmite, share identical electrical specifications (2 Ohms, ±5%, 10W), and are housed in the same axial package with matching physical dimensions.

The primary distinction between these parts is regulatory compliance status. The 30J2R0E carries ROHS3 compliance certification, whereas the 30J2R0 is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations requiring lead-free components, the 30J2R0E is the appropriate selection. For legacy systems or applications without RoHS requirements, either part is functionally equivalent.

Packaging differs between the two variants: the 30J2R0 is supplied in standard packaging, while the 30J2R0E is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 30J2R0E be used as a direct replacement for the 30J2R0 in existing designs?

A: Yes. The 30J2R0E is electrically and mechanically identical to the 30J2R0. Both components have the same resistance value (2 Ohms), tolerance (±5%), power rating (10W), physical dimensions (0.406" Dia x 1.843" L), and axial package configuration. They are pin-compatible and functionally interchangeable.

Q: What is the difference between the 30J2R0 and 30J2R0E?

A: The primary differences are RoHS compliance status and packaging format. The 30J2R0E is ROHS3 compliant, making it suitable for applications requiring lead-free components. The 30J2R0 is RoHS non-compliant. The 30J2R0E is supplied in bulk packaging, while the 30J2R0 uses standard packaging. Electrical and mechanical specifications are identical.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts are from the High Energy Wirewound series and share identical power dissipation ratings (10W), composition (wirewound), and physical form factor. Thermal performance and electrical behavior are equivalent.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For designs subject to RoHS directives or requiring lead-free components, specify the 30J2R0E. For applications without such requirements, either part is acceptable. Verify compliance requirements for your specific application and end-use market.

Q: Are these parts available in different packaging options?

A: Yes. The 30J2R0 is available in standard packaging, while the 30J2R0E is supplied in bulk packaging. Both use the same axial component format. Packaging selection may affect order quantities and inventory management but does not influence component performance.
