OD330J Equivalent & Substitute Parts

Part Overview

The OD330J is a 33 Ohm, ±5% tolerance, 1/4W (0.25W) through-hole axial resistor manufactured by Ohmite as part of the Little Demon® OD series. This carbon composition resistor features pulse withstanding capability and is designed for axial lead applications in electronic circuits requiring precision current limiting and voltage division.

The OD330J carries an obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure component availability for repairs, and support ongoing production requirements for legacy systems utilizing this specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OD330J is determined by strict equivalence across the following parameters:

• Resistance value: 33 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Carbon Composition (exact match required)
• Package configuration: Axial (exact match required)
• Physical dimensions: 0.098" Dia x 0.276" L / 2.50mm x 7.00mm (exact match required)
• Termination count: 2 leads (exact match required)

The OD330JE qualifies as a parametric equivalent substitute, meeting all electrical and mechanical specifications while differing only in packaging format (Strip versus standard packaging) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The OD330JE serves as a direct parametric equivalent to the OD330J. Both components are manufactured by Ohmite and share identical electrical specifications, physical dimensions, and functional characteristics.

The primary distinction between these parts is compliance certification. The OD330JE carries ROHS3 compliance, whereas the OD330J is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the OD330JE is the appropriate selection. Both components maintain REACH Unaffected status and identical ECCN and HTSUS classifications.

Both parts retain obsolete product status. Component selection should prioritize current inventory availability and application-specific compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can OD330JE be used as a direct replacement for OD330J in existing designs?

A: Yes. The OD330JE is electrically and mechanically equivalent to the OD330J. Both components feature identical 33 Ohm resistance, ±5% tolerance, 0.25W power rating, carbon composition construction, pulse withstanding capability, and axial package configuration with matching physical dimensions (0.098" Dia x 0.276" L).

Q: What is the difference between OD330J and OD330JE?

A: The components are parametrically identical. The OD330JE is supplied in Strip packaging format, whereas the OD330J uses standard packaging. Additionally, the OD330JE carries ROHS3 compliance certification, while the OD330J is RoHS non-compliant. Both maintain identical REACH Unaffected status.

Q: Are there any compatibility concerns when substituting OD330JE for OD330J?

A: No compatibility concerns exist. Identical axial lead configuration, physical dimensions, and electrical performance ensure direct board-level compatibility. PCB footprints, lead spacing, and mounting requirements remain unchanged.

Q: Which part should be selected for new designs or RoHS-compliant applications?

A: The OD330JE is the appropriate selection for applications requiring RoHS compliance. Both parts are obsolete; component availability should be confirmed with suppliers prior to design commitment.

Q: Do these components have any temperature or environmental operating limitations?

A: Operating temperature range data is not provided in the component specifications. Moisture Sensitivity Level 1 (Unlimited) indicates no moisture sensitivity restrictions. Consult manufacturer datasheets for complete environmental operating parameters.
