Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVZ2A103C04R00 is based on the following critical parameters that must remain constant or compatible:

• Resistance value: 10 kOhms (exact match required)
• Number of turns: 1.0 (single-turn operation)
• Adjustment type: Top Adjustment (functional requirement)
• Mounting type: Surface Mount (PCB integration requirement)
• RoHS3 compliance (regulatory requirement)
• MSL rating: 1 (moisture sensitivity compatibility)

The TC42X-2-103E qualifies as a substitute based on matching all critical parameters. Variations in power rating (0.05W to 0.1W), tolerance (±30% to ±25%), temperature coefficient (±500ppm/°C to ±250ppm/°C), resistive material (carbon to cermet), and termination style (gull wing to J lead) are within acceptable substitution criteria for this component category.

Parameter Comparison

Engineering Selection Recommendations

The TC42X-2-103E is the designated substitute for the obsolete PVZ2A103C04R00. Both components are manufactured by Bourns Inc. and maintain ROHS3 compliance and MSL rating 1 status. The TC42X-2-103E is currently in active production status, ensuring long-term availability and supply chain continuity.

The TC42X-2-103E provides improved specifications in power rating (0.1W versus 0.05W), tolerance (±25% versus ±30%), and temperature coefficient (±250ppm/°C versus ±500ppm/°C). The shift from carbon to cermet resistive material in the substitute part offers enhanced stability and performance characteristics. PCB layout modifications are required to accommodate the J lead termination style and revised dimensional specifications (0.102" x 0.087" face versus 0.087" x 0.083" face).

Frequently Asked Questions (FAQ)

Q: Can the TC42X-2-103E directly replace the PVZ2A103C04R00 without PCB modifications?

A: PCB layout modifications are required. The termination style differs (J lead versus gull wing, 90° bend), and the component dimensions vary. Footprint redesign is necessary for proper mounting and electrical connection.

Q: What is the impact of the higher power rating in the TC42X-2-103E?

A: The increased power rating (0.1W versus 0.05W) provides additional thermal margin and operational headroom. This change is compatible with applications designed for the original 0.05W specification.

Q: Are there compliance differences between the two parts?

A: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL rating 1. No compliance barriers exist for substitution.

Q: How does the resistive material change affect circuit performance?

A: The shift from carbon to cermet material improves temperature coefficient performance (±250ppm/°C versus ±500ppm/°C) and tolerance (±25% versus ±30%), resulting in enhanced stability across operating temperature ranges.

Q: Is the TC42X-2-103E available in the same packaging format?

A: The TC42X-2-103E is supplied in Tape & Reel (TR) packaging, whereas the original part packaging specification was not provided. Confirm packaging requirements with procurement specifications.
