Substitute Part Grouping Explanation

Substitution of the TWM3J1K0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1 kOhms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Metal Oxide Film
• Package configuration: Radial leads
• Operating temperature range: -55°C ~ 275°C
• Temperature coefficient: ±350ppm/°C
• Features: Flame Proof, Safety

The TWM3J1K0E qualifies as a direct substitute because it maintains identical electrical specifications and mechanical compatibility while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TWM3J1K0E is the appropriate substitute for the obsolete TWM3J1K0. Both components are manufactured by Ohmite within the TWM series and maintain identical electrical and mechanical specifications. The primary distinction is product status: the TWM3J1K0E is currently active in production, ensuring availability for procurement and support.

The TWM3J1K0E additionally provides RoHS compliance, whereas the original TWM3J1K0 is non-compliant. This compliance improvement aligns with current regulatory requirements for electronic component manufacturing and distribution.

Dimensional compatibility is confirmed: both parts maintain the same seated height of 1.024" (26.00mm) and radial package configuration, ensuring direct mechanical fit in existing circuit board layouts.

Frequently Asked Questions (FAQ)

Q: Can the TWM3J1K0E replace the TWM3J1K0 in existing designs?

A: Yes. The TWM3J1K0E maintains identical electrical specifications (1 kOhms ±5%, 3W, metal oxide film composition) and mechanical dimensions (radial package, 26.00mm seated height). Direct substitution is supported without circuit redesign.

Q: What is the primary reason for substitution?
