Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVZ3A503C01B00 is determined by the following critical parameters:

• Resistance Value: 50 kOhms (exact match required)
• Power Rating: 0.1W minimum (equal or higher acceptable)
• Termination Style: J Lead (mechanical and electrical compatibility)
• Mounting Type: Surface Mount (PCB layout compatibility)
• Number of Turns: 1.0 Turn (adjustment range consistency)
• Adjustment Type: Top Adjustment (user interface compatibility)
• Compliance: RoHS3 and REACH status alignment

The TC33X-1-503E qualifies as a direct substitute based on matching all critical parameters. Variations in resistive material (Cermet vs. Carbon), tolerance, temperature coefficient, and physical dimensions remain within acceptable engineering substitution criteria for this component category.

Parameter Comparison

Engineering Selection Recommendations

The TC33X-1-503E is the qualified substitute for the obsolete PVZ3A503C01B00. Both components are manufactured by Bourns Inc. and maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current production requirements.

The TC33X-1-503E carries Active product status, providing assured long-term availability and supply chain stability compared to the Obsolete PVZ3A503C01B00. The substitute demonstrates improved electrical performance through tighter tolerance (±25% vs. ±30%) and lower temperature coefficient (±250ppm/°C vs. ±500ppm/°C).

Physical dimensions differ slightly between the two parts. The TC33X-1-503E measures 0.150" x 0.142" (3.80mm x 3.60mm) compared to the PVZ3A503C01B00 at 0.126" x 0.122" (3.20mm x 3.10mm). PCB layout verification is required to confirm accommodation of the larger substitute footprint.

Frequently Asked Questions (FAQ)

Q: Can TC33X-1-503E replace PVZ3A503C01B00 in existing designs?

A: Yes. Both components share identical resistance value (50 kOhms), power rating (0.1W), number of turns (1.0), adjustment type (Top Adjustment), mounting type (Surface Mount), and termination style (J Lead). Physical dimensions require PCB layout verification due to the slightly larger footprint of the TC33X-1-503E.

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

A: The primary differences are resistive material (Carbon vs. Cermet), tolerance specification (±30% vs. ±25%), temperature coefficient (±500ppm/°C vs. ±250ppm/°C), and physical dimensions. The TC33X-1-503E offers improved electrical stability and tighter tolerance performance.

Q: Is the TC33X-1-503E available in the same packaging as the PVZ3A503C01B00?

A: The TC33X-1-503E is supplied in Tape & Reel (TR) packaging. Packaging compatibility should be confirmed with procurement requirements for your application.

Q: Are both parts RoHS compliant?

A: Yes. Both the PVZ3A503C01B00 and TC33X-1-503E are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Why is the PVZ3A503C01B00 marked as Obsolete?

A: The PVZ3A503C01B00 has reached end-of-life status. The TC33X-1-503E from the active Trimpot® TC33 series represents the current equivalent offering from Bourns Inc. for this resistance and power rating combination.
