Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVZ3G103C01R00 is based on the following critical parameters that must remain constant or compatible:

• Resistance value: 10 kOhms (exact match required)
• Mounting type: Surface Mount (mechanical compatibility)
• Termination style: J Lead (PCB footprint compatibility)
• Adjustment type: Top Adjustment (functional requirement)
• Number of turns: 1 (operational characteristic)

The TC33X-2-103E qualifies as a direct substitute based on matching all critical parameters. Variations in power rating (0.1W to 0.15W), tolerance (±30% to ±25%), temperature coefficient (±500ppm/°C to ±250ppm/°C), resistive material (carbon to cermet), and physical dimensions are within acceptable engineering substitution criteria for this component category, provided the application does not impose strict constraints on these secondary parameters.

Parameter Comparison

Engineering Selection Recommendations

The TC33X-2-103E is the active equivalent for the obsolete PVZ3G103C01R00. Both components are manufactured by Bourns Inc. and maintain ROHS3 compliance and unlimited moisture sensitivity rating. The TC33X-2-103E offers improved specifications including higher power rating (0.15W versus 0.1W), tighter tolerance (±25% versus ±30%), and superior temperature stability (±250ppm/°C versus ±500ppm/°C). The shift from carbon to cermet resistive material in the substitute provides enhanced performance characteristics suitable for precision trimmer applications.

Physical dimension differences (square 3.10mm versus rectangular 3.80mm x 3.60mm) require PCB layout verification to confirm footprint compatibility. Both components share identical J Lead termination and top adjustment functionality, ensuring functional interchangeability in applications where board space permits the slightly larger substitute package.

Frequently Asked Questions (FAQ)

Q: Can TC33X-2-103E directly replace PVZ3G103C01R00 on existing PCBs?

A: Direct replacement requires verification of available PCB space. The TC33X-2-103E has a larger rectangular footprint (3.80mm x 3.60mm) compared to the square PVZ3G103C01R00 (3.10mm x 3.10mm). J Lead termination compatibility is maintained. PCB layout review is necessary before implementation.

Q: What are the key differences between these components?

A: Critical parameters remain identical: 10 kOhms resistance, 1-turn top adjustment, J Lead termination, and surface mount configuration. Secondary differences include power rating increase (0.1W to 0.15W), tolerance improvement (±30% to ±25%), temperature coefficient enhancement (±500ppm/°C to ±250ppm/°C), and resistive material change (carbon to cermet).

Q: Are both components RoHS compliant?

A: Both PVZ3G103C01R00 and TC33X-2-103E are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), meeting current environmental and reliability standards.

Q: Why is the original part obsolete?

A: The PVZ3G103C01R00 has been discontinued by Bourns Inc. The TC33X-2-103E represents the active product line continuation with enhanced specifications and maintained supply availability.

Q: Does the cermet material in TC33X-2-103E affect circuit performance?

A: Cermet resistive material provides superior temperature stability and tolerance characteristics compared to carbon. For applications sensitive to temperature coefficient performance, the TC33X-2-103E offers improved specifications. Functional compatibility is maintained for standard trimmer potentiometer applications.
