Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 3142W202P is determined by the following critical parameters that must remain constant or compatible:

Fixed Parameters (Must Match):

• Resistance value: 2 kOhms
• Termination style: J Lead
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Surface Mount
• Number of turns: 1

Flexible Parameters (May Vary Within Acceptable Ranges):

• Power rating: Substitute must equal or exceed 0.15W
• Tolerance: Substitute may have tighter tolerance (lower percentage acceptable)
• Temperature coefficient: Substitute may have lower temperature coefficient (improved stability acceptable)
• Physical dimensions: Substitute may have different footprint if PCB layout permits
• Product status: Active status preferred for long-term availability

The Bourns PVG3A202C01R00 qualifies as a direct substitute based on matching all fixed parameters while providing enhanced specifications in power rating (0.25W vs. 0.15W), tolerance (±20% vs. ±25%), and temperature coefficient (±150ppm/°C vs. ±250ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

The Bourns PVG3A202C01R00 is the qualified substitute for the obsolete TE Connectivity 3142W202P based on the following engineering criteria:

Functional Equivalence: Both components share identical resistance value (2 kOhms), termination style (J Lead), adjustment type (top adjustment), resistive material (cermet), and mounting configuration (surface mount). The 1-turn adjustment specification is maintained across both parts.

Compliance Status: The Bourns substitute maintains ROHS3 compliance and MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards. The substitute's active product status provides assured long-term availability and supply chain continuity compared to the obsolete TE Connectivity original.

Performance Enhancement: The substitute provides superior electrical characteristics with 0.25W power rating (67% higher than original 0.15W), tighter tolerance specification (±20% vs. ±25%), and improved temperature stability (±150ppm/°C vs. ±250ppm/°C). These enhancements do not compromise circuit functionality and provide design margin.

Physical Compatibility: The Bourns component features a smaller rectangular footprint (3.60mm x 3.40mm vs. 4.50mm x 4.00mm), enabling space optimization on PCB layouts. The reduced size does not affect electrical performance or adjustment accessibility.

Supply Availability: The Bourns PVG3A202C01R00 is available in Cut Tape and Digi-Reel packaging with 2400 pieces in current inventory, ensuring immediate procurement capability for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the Bourns PVG3A202C01R00 directly replace the TE Connectivity 3142W202P in existing designs?

A: Yes. Both components share identical resistance value, J lead termination, top adjustment type, cermet construction, and surface mount configuration. The Bourns substitute is electrically and mechanically compatible for direct substitution in PCB layouts.

Q: What is the significance of the higher power rating on the Bourns substitute?

A: The Bourns PVG3A202C01R00 is rated at 0.25W compared to the original 0.15W. This higher power rating provides additional thermal margin and allows operation in applications with higher power dissipation requirements. The substitute will not cause circuit malfunction in applications designed for the original 0.15W component.

Q: Does the smaller physical size of the Bourns part affect PCB layout compatibility?

A: The Bourns substitute measures 3.60mm x 3.40mm compared to the original 4.50mm x 4.00mm. The reduced footprint is compatible with existing PCB layouts designed for the larger TE Connectivity component. PCB designers may optimize board space by utilizing the smaller footprint, but existing layouts require no modification for functional compatibility.

Q: Are there any tolerance or temperature coefficient differences that affect circuit performance?

A: The Bourns substitute features ±20% tolerance versus the original ±25%, and ±150ppm/°C temperature coefficient versus ±250ppm/°C. These specifications represent improvements in accuracy and thermal stability. Applications designed for the original component specifications will function within acceptable parameters with the substitute.

Q: What packaging options are available for the Bourns substitute?

A: The Bourns PVG3A202C01R00 is supplied in Cut Tape (CT) and Digi-Reel packaging formats, suitable for both manual and automated assembly processes. The original TE Connectivity component packaging information was not specified in available documentation.

Q: Is the Bourns substitute compliant with current environmental and regulatory standards?

A: Yes. The Bourns PVG3A202C01R00 is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating. The component meets current manufacturing and environmental requirements for commercial and industrial applications.

Q: Why is the TE Connectivity 3142W202P classified as obsolete?

A: Obsolete status indicates the component is no longer manufactured by TE Connectivity and is not available through standard distribution channels. The Bourns PVG3A202C01R00 provides functional equivalence with active product status and assured supply availability.
