Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC03X-2-502E is determined by strict equivalence across the following critical parameters:

• Resistance value: 5 kOhms
• Power rating: 0.1W
• Tolerance: ±25%
• Temperature coefficient: ±250ppm/°C
• Number of turns: 1
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Surface Mount
• Termination style: J Lead

The TC33X-2-502E qualifies as a direct substitute based on matching all electrical and mechanical parameters. Dimensional variations between the TC03 and TC33 series are within acceptable tolerances for PCB layout compatibility. The TC33X series represents the active production equivalent, with superior inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The TC33X-2-502E is the appropriate substitute for the obsolete TC03X-2-502E. Both components maintain identical electrical specifications and comply with ROHS3 and REACH requirements. The TC33X series is in active production status, ensuring long-term availability and supply chain continuity. The TC33X-2-502E is available in Tape & Reel packaging, supporting automated assembly processes. Dimensional differences between the two series are minor and do not impact functional performance or PCB layout compatibility for standard applications.

Frequently Asked Questions (FAQ)

Q: Can the TC33X-2-502E be used as a direct replacement for TC03X-2-502E in existing designs?

A: Yes. Both components share identical electrical parameters: 5 kOhms resistance, 0.1W power rating, ±25% tolerance, ±250ppm/°C temperature coefficient, and cermet resistive material. The face dimensions differ slightly (0.140" x 0.118" versus 0.150" x 0.142"), but this variation is within acceptable tolerances for standard PCB layouts.

Q: What is the primary advantage of substituting TC03X-2-502E with TC33X-2-502E?

A: The TC33X-2-502E is in active production, whereas the TC03X-2-502E is obsolete. This ensures reliable procurement, superior inventory availability (95,300 units in stock versus 1,122 units), and long-term supply chain support.

Q: Are there packaging differences between these components?

A: Yes. The TC03X-2-502E is supplied in bulk packaging, while the TC33X-2-502E is available in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated assembly and reduces handling costs in high-volume production environments.

Q: Do both components meet the same compliance standards?

A: Yes. Both the TC03X-2-502E and TC33X-2-502E are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level). They are functionally equivalent from a regulatory and environmental compliance perspective.

Q: Are there any electrical performance differences between the TC03 and TC33 series?

A: No. For the 5 kOhms, 0.1W configuration, both series deliver identical electrical performance: same resistance value, power rating, tolerance, and temperature coefficient. Series differences are primarily related to mechanical design and manufacturing processes, not electrical characteristics.
