Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3364B-1-502E is based on the following critical parameters that must remain constant or compatible:

• Resistance value: 5 kOhms (exact match required)
• Termination style: J Lead (mechanical and electrical compatibility)
• Adjustment type: Top Adjustment (functional requirement)
• Resistive material: Cermet (performance characteristic)
• Mounting type: Surface Mount (PCB assembly compatibility)
• Temperature coefficient: ±250ppm/°C (thermal stability requirement)
• Tolerance: ±25% (accuracy specification)

The TC33X-2-502E qualifies as a substitute based on matching all critical parameters. The primary difference is the power rating reduction from 0.2W to 0.1W, which represents a design constraint that must be evaluated within the specific application context.

Parameter Comparison

Engineering Selection Recommendations

The TC33X-2-502E is an active product from Bourns Inc. and represents the current generation equivalent to the obsolete 3364B-1-502E. Both components maintain identical electrical specifications for resistance, tolerance, temperature coefficient, and adjustment characteristics. Both are ROHS3 compliant with MSL rating 1, ensuring regulatory and environmental compatibility.

The primary design consideration is the power rating differential: the TC33X-2-502E operates at 0.1W versus the original 0.2W specification. This reduction requires confirmation that the application dissipates power within the lower threshold. The TC33X-2-502E also features a slightly reduced footprint (0.150" x 0.142" versus 0.165" x 0.150"), which may provide layout advantages in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the TC33X-2-502E directly replace the 3364B-1-502E in existing designs?

A: Direct replacement is possible when application power dissipation does not exceed 0.1W. All electrical parameters, termination style, and adjustment mechanisms are identical. PCB layout may require minor adjustment due to the reduced footprint of the TC33X-2-502E.

Q: What is the significance of the power rating difference?

A: The power rating indicates maximum continuous power dissipation. The TC33X-2-502E is rated for 0.1W (1/10W) compared to the original 0.2W (1/5W). Applications requiring higher power dissipation must retain the original specification or identify alternative components with higher power ratings.

Q: Are both components available in the same packaging format?

A: The 3364B-1-502E is available in standard packaging, while the TC33X-2-502E is supplied in Tape & Reel (TR) format. Both maintain identical J Lead termination and surface mount compatibility.

Q: Do both components meet current regulatory requirements?

A: Both the 3364B-1-502E and TC33X-2-502E are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement.

Q: What is the footprint difference between these components?

A: The 3364B-1-502E has a rectangular face of 0.165" x 0.150" (4.20mm x 3.80mm), while the TC33X-2-502E measures 0.150" x 0.142" (3.80mm x 3.60mm). The TC33X-2-502E is slightly smaller, which may affect PCB layout compatibility.
