Key Parameters

Substitute Part Grouping Explanation

Substitution of the TWM5J330 is determined by strict equivalence across the following parameters:

• Resistance value: 330 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Metal Oxide Film
• Package configuration: Radial
• Operating temperature range: -55°C to 275°C
• Temperature coefficient: ±350ppm/°C
• Physical dimensions: 0.492" L x 0.354" W with maximum seated height of 1.024"

The TWM5J330E meets all these criteria and is classified as an active product, providing direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TWM5J330E is the direct active equivalent for the obsolete TWM5J330. Both components share identical electrical specifications, mechanical dimensions, and thermal characteristics. The primary distinction is product status and regulatory compliance: the TWM5J330E is actively manufactured and ROHS3 compliant, whereas the TWM5J330 is obsolete and RoHS non-compliant. For new designs and ongoing procurement, the TWM5J330E is the appropriate selection. Existing designs using the TWM5J330 can transition to the TWM5J330E without circuit modification or re-qualification, provided RoHS compliance requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can the TWM5J330E directly replace the TWM5J330 in existing circuits?

A: Yes. The TWM5J330E is electrically and mechanically identical to the TWM5J330. All electrical parameters, physical dimensions, and thermal characteristics are equivalent. Direct substitution is possible without circuit redesign.

Q: What is the primary reason to transition from TWM5J330 to TWM5J330E?

A: The TWM5J330 is obsolete and no longer manufactured. The TWM5J330E is the active equivalent part maintained in production by Ohmite. Additionally, the TWM5J330E is ROHS3 compliant, whereas the TWM5J330 is RoHS non-compliant.

Q: Are there any packaging differences between these parts?

A: Both components use radial package configuration with identical physical dimensions: 0.492" L x 0.354" W (12.50mm x 9.00mm) and maximum seated height of 1.024" (26.00mm). The TWM5J330E is supplied in bulk packaging, while the TWM5J330 was supplied in standard packaging.

Q: Do the electrical specifications differ between TWM5J330 and TWM5J330E?

A: No. Both parts have identical resistance (330 Ohms), tolerance (±5%), power rating (5W), temperature coefficient (±350ppm/°C), and operating temperature range (-55°C to 275°C).

Q: Is the TWM5J330E suitable for high-temperature applications?

A: Yes. The TWM5J330E operates across the full temperature range of -55°C to 275°C with a temperature coefficient of ±350ppm/°C, maintaining performance in high-temperature industrial environments.
