Substitute Part Grouping Explanation

Substitute parts for the TWM5J3K3 are identified based on electrical and mechanical parameter equivalence. The following criteria determine substitutability:

• Resistance value: 3.3 kOhms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Metal Oxide Film
• Package configuration: Radial with 2 terminations
• Operating temperature range: -55°C ~ 275°C minimum
• Temperature coefficient: ±350ppm/°C
• Physical dimensions: 0.492" L x 0.354" W with maximum seated height of 1.024"

Parts meeting all these electrical and mechanical specifications are classified as direct equivalents and may be used as substitutes in applications originally designed for the TWM5J3K3.

Parameter Comparison

Engineering Selection Recommendations

The TWM5J3K3E is the direct equivalent substitute for the obsolete TWM5J3K3. Both components are manufactured by Ohmite and share identical electrical specifications and physical dimensions. The primary distinction is product status and regulatory compliance: the TWM5J3K3E is active production and ROHS3 compliant, whereas the TWM5J3K3 is obsolete and RoHS non-compliant. For new designs and ongoing production requiring RoHS compliance, the TWM5J3K3E is the appropriate selection. Both components maintain REACH Unaffected status and identical ECCN and HTSUS classifications.
