TE Connectivity 3150W202P Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3150W202P is a 2 kOhms surface mount trimmer potentiometer rated at 0.2W (1/5W) with 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 3150 series from TE Connectivity (Citec) is no longer in active production, making substitute parts essential for procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 3150W202P is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2 kOhms
• Termination style: J Lead
• Mounting type: Surface Mount
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Number of turns: 1.0 Turn
• Tolerance: ±25%
• Temperature coefficient: ±250ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation:

• Power rating: The substitute part may have a lower power rating (0.1W) provided the application does not exceed this limit. The original 0.2W rating establishes the maximum power dissipation requirement; lower-rated substitutes are acceptable for applications within their power envelope.
• Physical dimensions: Minor dimensional variations are acceptable provided the J Lead termination and surface mount footprint remain compatible with the original PCB design.

The Bourns TC33X-1-202E meets all mandatory matching parameters and is classified as an active product, providing long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The Bourns TC33X-1-202E (Trimpot® TC33 - Open Frame series) is the qualified substitute for the obsolete TE Connectivity 3150W202P based on the following engineering criteria:

Compliance and Certification: Both parts maintain ROHS3 compliance and identical moisture sensitivity level (MSL 1 - Unlimited), ensuring regulatory and environmental compatibility across supply chain transitions.

Electrical Equivalence: Resistance, tolerance, temperature coefficient, and adjustment characteristics are identical. The substitute part operates within the same electrical performance envelope for applications designed within the 0.1W power specification.

Product Status: The Bourns TC33X-1-202E is an active product with confirmed inventory availability (5768 pieces in stock), providing immediate procurement capability and long-term supply chain security compared to the obsolete TE Connectivity part.

Physical Compatibility: The J Lead termination and surface mount configuration are functionally equivalent. The slightly smaller physical dimensions of the Bourns part (0.150" x 0.142" versus 0.165" x 0.150") represent a compatible variation that does not compromise PCB layout or assembly processes.

Power Rating Consideration: Applications operating at or below 0.1W power dissipation can directly substitute the Bourns TC33X-1-202E. Applications requiring the full 0.2W rating of the original part require thermal analysis to confirm the substitute part's adequacy within the specific circuit design.

Frequently Asked Questions (FAQ)

Q: Can the Bourns TC33X-1-202E directly replace the TE Connectivity 3150W202P in all applications?

A: Direct substitution is valid for applications operating at or below 0.1W power dissipation. The substitute part has a lower power rating (0.1W versus 0.2W). Applications requiring the full 0.2W rating must evaluate whether the substitute part's thermal characteristics are adequate for the specific circuit design.

Q: Are the physical dimensions compatible with the original PCB layout?

A: The Bourns TC33X-1-202E has slightly smaller dimensions (0.150" x 0.142" versus 0.165" x 0.150"). The J Lead termination and surface mount footprint remain compatible. PCB layout verification is recommended to confirm adequate clearance and assembly compatibility.

Q: What is the difference between the 3150 series and the TC33X series?

A: The TE Connectivity 3150 series is obsolete. The Bourns TC33X (Trimpot® TC33 - Open Frame) is an active product line offering equivalent electrical specifications and superior supply chain availability. Both use Cermet resistive material and J Lead termination.

Q: Are RoHS and MSL ratings identical?

A: Yes. Both the TE Connectivity 3150W202P and Bourns TC33X-1-202E are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, ensuring equivalent environmental and regulatory compliance.

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

A: The Bourns TC33X-1-202E is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original TE Connectivity part packaging specification was not provided in the reference data.

Q: Is the ±25% tolerance maintained in the substitute part?

A: Yes. Both parts maintain ±25% tolerance and ±250ppm/°C temperature coefficient, ensuring equivalent performance stability across temperature ranges and production variations.
