TE Connectivity 3142W501P Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3142W501P is a 500 Ohm surface mount trimmer potentiometer with 0.15W power rating, J lead termination, and top adjustment capability. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The 3142 series from TE Connectivity Passive Product has been superseded by newer trimmer potentiometer offerings, making substitute part selection critical for design continuity and supply chain management.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 3142W501P is determined by the following critical parameters that must remain constant or be compatible with the original design:

Fixed Parameters (Must Match):

• Resistance value: 500 Ohms
• Termination style: J Lead
• Adjustment type: Top Adjustment
• Mounting type: Surface Mount
• Resistive material: Cermet
• Number of turns: 1 Turn

Compatible Parameters (May Vary Within Acceptable Ranges):

• Power rating: Substitute must equal or exceed 0.15W
• Tolerance: Substitute tolerance of ±20% is acceptable for applications originally designed with ±25%
• Temperature coefficient: Substitute value of ±150ppm/°C is acceptable for applications originally designed with ±250ppm/°C
• Physical size: Substitute dimensions must be compatible with PCB layout and mechanical constraints

The Bourns PVG3A501C01R00 meets all fixed parameter requirements and provides improved specifications in power rating (0.25W versus 0.15W), tolerance (±20% versus ±25%), and temperature coefficient (±150ppm/°C versus ±250ppm/°C), making it a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The Bourns PVG3A501C01R00 is the qualified substitute for the obsolete TE Connectivity 3142W501P based on the following engineering criteria:

Functional Equivalence: Both components share identical resistance value, termination style, adjustment type, mounting configuration, and resistive material composition. The 1-turn cermet trimmer potentiometer design is functionally equivalent.

Specification Improvements: The substitute part provides enhanced performance characteristics including higher power dissipation capability (0.25W versus 0.15W), tighter tolerance specification (±20% versus ±25%), and superior temperature stability (±150ppm/°C versus ±250ppm/°C). These improvements ensure the substitute part meets or exceeds the original design requirements.

Compliance Status: Both components maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. The substitute part is REACH Unaffected, confirming regulatory alignment with current environmental standards.

Product Availability: The TE Connectivity 3142W501P is obsolete with limited remaining inventory. The Bourns PVG3A501C01R00 is active production with substantial inventory availability (8457 pieces in stock), ensuring long-term supply chain continuity.

Physical Compatibility: The substitute part features a smaller footprint (3.60mm x 3.40mm versus 4.50mm x 4.00mm), which is compatible with PCB layouts designed for the original component. The reduced size provides additional design flexibility for space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the Bourns PVG3A501C01R00 be used as a direct replacement for the TE Connectivity 3142W501P in existing designs?

A: Yes. The substitute part maintains identical electrical specifications for resistance, termination style, adjustment type, and mounting configuration. The improved power rating, tolerance, and temperature coefficient specifications ensure compatibility with designs originally specified for the obsolete part.

Q: What is the significance of the smaller physical dimensions of the substitute part?

A: The Bourns PVG3A501C01R00 measures 3.60mm x 3.40mm compared to the original 4.50mm x 4.00mm. This smaller footprint is compatible with existing PCB layouts and provides additional design flexibility. PCB layout verification is necessary to confirm adequate clearance and component placement compatibility.

Q: Are there any electrical performance differences between the two parts?

A: The substitute part provides superior electrical performance. The power rating increases from 0.15W to 0.25W, tolerance tightens from ±25% to ±20%, and temperature coefficient improves from ±250ppm/°C to ±150ppm/°C. These enhancements ensure the substitute part meets or exceeds original design specifications.

Q: What is the packaging difference between these components?

A: The TE Connectivity 3142W501P is supplied in standard packaging. The Bourns PVG3A501C01R00 is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations and provides improved handling efficiency.

Q: Are both components RoHS compliant?

A: Yes. Both the TE Connectivity 3142W501P and Bourns PVG3A501C01R00 are ROHS3 compliant, confirming adherence to current environmental and hazardous substance restrictions.

Q: What is the moisture sensitivity level for these components?

A: Both components have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage procedures are applicable without special moisture control requirements.

Q: Why is the TE Connectivity 3142W501P classified as obsolete?

A: The 3142 series has been discontinued by TE Connectivity Passive Product. The Bourns PVG3A501C01R00 represents the current active production equivalent that fulfills the same functional requirements with enhanced specifications and improved long-term availability.
