Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TWM3J200 is determined by strict equivalence across the following parameters:

• Resistance value: 200 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Metal Oxide Film
• Package configuration: Radial with 2 terminations
• Temperature coefficient: ±350ppm/°C
• Operating temperature range: -55°C to 275°C
• Physical dimensions: 0.492" L x 0.354" W with maximum seated height of 1.024"

The TWM3J200E meets all electrical and mechanical parameters required for direct substitution. The primary distinction is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TWM3J200E is the direct functional equivalent to the obsolete TWM3J200. Both components share identical electrical specifications, composition, and mechanical dimensions. The TWM3J200E maintains active product status with Ohmite, ensuring continued availability and supply chain reliability.

The TWM3J200E provides ROHS3 compliance, whereas the original TWM3J200 is RoHS non-compliant. For applications subject to RoHS regulations or requiring compliance documentation, the TWM3J200E is the appropriate selection. Both components maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can TWM3J200E replace TWM3J200 in existing designs?

A: Yes. The TWM3J200E is electrically and mechanically equivalent. All critical parameters including resistance, tolerance, power rating, temperature coefficient, and physical dimensions are identical. Direct substitution is valid for applications where the original TWM3J200 was specified.

Q: What is the primary difference between TWM3J200 and TWM3J200E?

A: The TWM3J200 is obsolete, while TWM3J200E is active. The TWM3J200E is ROHS3 compliant, whereas the TWM3J200 is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The TWM3J200 is supplied in standard packaging, while the TWM3J200E is supplied in bulk packaging. Both maintain identical radial lead configuration and physical dimensions suitable for through-hole PCB assembly.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both components deliver identical electrical characteristics and operating parameters.

Q: What is the temperature coefficient significance for these resistors?

A: The ±350ppm/°C temperature coefficient indicates resistance value variation across the -55°C to 275°C operating range. Both TWM3J200 and TWM3J200E maintain this specification, ensuring consistent performance across temperature extremes.
