PVZ3G104C01R00 Equivalent & Substitute Parts

Part Overview

The PVZ3G104C01R00 is a 100 kOhm, 0.1W surface mount trimmer potentiometer manufactured by Bourns Inc. in the PVZ3 series. This component features a carbon resistive element with 1-turn top adjustment and J-lead termination for SMD applications. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The TC33X-2-104E qualifies as a direct substitute based on the following critical parameters:

• Identical resistance value: 100 kOhms
• Identical power rating: 0.1W (1/10W)
• Identical number of turns: 1
• Identical adjustment type: Top Adjustment
• Identical mounting type: Surface Mount
• Identical termination style: J Lead
• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)

Variations exist in resistive material (Cermet vs. Carbon), tolerance (±25% vs. ±30%), temperature coefficient (±250ppm/°C vs. ±500ppm/°C), and physical dimensions (Rectangular 0.150" x 0.142" vs. Square 0.122" x 0.122"). These differences do not preclude substitution when the application requirements permit the tighter tolerance and improved temperature stability of the TC33X-2-104E.

Parameter Comparison

Engineering Selection Recommendations

The TC33X-2-104E is the designated substitute for the obsolete PVZ3G104C01R00. Both components maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility. The TC33X-2-104E offers active product status with established supply chain availability, addressing the obsolescence of the original part.

The TC33X-2-104E provides improved performance characteristics through tighter tolerance (±25% vs. ±30%) and superior temperature stability (±250ppm/°C vs. ±500ppm/°C). The shift from carbon to cermet resistive material in the substitute contributes to these enhancements. Physical dimension differences require verification of PCB layout compatibility, as the TC33X-2-104E occupies a slightly larger footprint (Rectangular 0.150" x 0.142" vs. Square 0.122" x 0.122").

Frequently Asked Questions (FAQ)

Q: Can the TC33X-2-104E directly replace the PVZ3G104C01R00 in existing designs?

A: Functional substitution is valid based on matching resistance, power rating, termination style, and adjustment characteristics. PCB layout verification is required due to dimensional differences. The TC33X-2-104E's larger footprint may necessitate minor layout adjustments.

Q: What are the key differences between these two parts?

A: Primary differences include resistive material (Cermet vs. Carbon), tolerance specification (±25% vs. ±30%), temperature coefficient (±250ppm/°C vs. ±500ppm/°C), and physical dimensions. The TC33X-2-104E delivers superior performance stability with tighter tolerance and lower temperature drift.

Q: Are both parts RoHS compliant?

A: Both the PVZ3G104C01R00 and TC33X-2-104E are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the MSL rating for these components?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Why is the PVZ3G104C01R00 marked as obsolete?

A: The PVZ3 series has been superseded by the active TC33X series. The TC33X-2-104E represents the current production equivalent with enhanced specifications and ongoing manufacturer support.
