Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVZ3A103C01R00 is determined by the following critical parameters:

• Resistance value: 10 kOhms (exact match required)
• Power rating: 0.1W minimum
• Termination style: J Lead (mechanical and electrical compatibility)
• Mounting type: Surface Mount
• Adjustment type: Top Adjustment
• Number of turns: 1.0 Turn

The TC33X-1-103E qualifies as a substitute based on matching all critical parameters. Variations in resistive material (carbon versus cermet), tolerance specification, temperature coefficient, and physical dimensions are within acceptable substitution criteria for this component category, provided the core functional parameters remain compatible with the application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TC33X-1-103E is an active product from Bourns Inc. and represents the primary substitute for the obsolete PVZ3A103C01R00. Both components maintain ROHS3 compliance and unlimited moisture sensitivity level ratings, ensuring regulatory and environmental compatibility.

The TC33X-1-103E offers improved tolerance specification (±25% versus ±30%) and superior temperature coefficient performance (±250ppm/°C versus ±500ppm/°C), which may provide enhanced stability in temperature-sensitive applications. The cermet resistive material in the TC33X-1-103E provides different performance characteristics compared to the carbon material in the PVZ3A103C01R00.

Physical dimension differences exist between the two components. The TC33X-1-103E has a larger face dimension (0.150" x 0.142" versus 0.126" x 0.122"), which requires verification against PCB layout constraints and available mounting space in the target application.

Frequently Asked Questions (FAQ)

Q: Can the TC33X-1-103E be used as a direct replacement for the PVZ3A103C01R00?

A: The TC33X-1-103E matches all critical functional parameters: 10 kOhms resistance, 0.1W power rating, J Lead termination, surface mount configuration, and 1.0 turn top adjustment. Substitution is electrically and mechanically feasible. However, the larger physical dimensions must be confirmed against available PCB space before implementation.

Q: What are the differences in resistive material between these components?

A: The PVZ3A103C01R00 uses carbon resistive material, while the TC33X-1-103E uses cermet material. Cermet construction typically provides improved temperature stability and tolerance characteristics, as reflected in the TC33X-1-103E specifications.

Q: Are there compliance or certification differences between these parts?

A: Both components are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings. No compliance or certification barriers exist for substitution.

Q: What impact do tolerance and temperature coefficient differences have on substitution?

A: The TC33X-1-103E provides tighter tolerance (±25% versus ±30%) and lower temperature coefficient (±250ppm/°C versus ±500ppm/°C). These represent performance improvements that enhance precision and thermal stability. Applications with strict tolerance or temperature requirements may benefit from these characteristics.

Q: Is the size difference between these components a concern?

A: The TC33X-1-103E has a larger face dimension (3.80mm x 3.60mm versus 3.20mm x 3.10mm). PCB layout verification is required to confirm that available mounting space accommodates the larger component footprint.

Q: What is the availability status of the TC33X-1-103E?

A: The TC33X-1-103E carries Active product status with 10,300 pieces in stock, ensuring reliable supply chain availability for production and replacement applications.
