TE Connectivity 3152W204P Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3152W204P is a 200 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 3152W204P belongs to the TE Connectivity 3150 series and utilizes cermet resistive material for stable performance across temperature ranges.

Due to its obsolete status, sourcing new inventory of the 3152W204P presents supply chain challenges. Active equivalent parts with matching electrical and mechanical specifications are required to maintain design continuity and ensure component availability for manufacturing operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3152W204P is determined by equivalence across the following critical parameters:

Electrical Parameters (Required Match):

• Resistance value: 200 kOhms
• Temperature coefficient: ±250ppm/°C
• Tolerance: ±25%
• Number of turns: 1 Turn
• Adjustment type: Top Adjustment

Mechanical Parameters (Required Match):

• Mounting type: Surface Mount
• Termination style: J Lead
• Resistive material: Cermet

Acceptable Variation:

• Power rating: Substitute parts rated at 0.1W (1/10W) are acceptable for applications where the original 0.2W (1/5W) rating exceeds operational requirements
• Face dimensions: Minor dimensional variations within the rectangular form factor are acceptable provided J Lead termination and surface mount compatibility are maintained

The Bourns TC33X-1-204E meets all critical electrical and mechanical parameters while offering active product status and improved supply availability.

Engineering Selection Recommendations

Primary Substitute: Bourns TC33X-1-204E

The Bourns TC33X-1-204E is the recommended substitute for the obsolete TE Connectivity 3152W204P based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters match the original specification: 200 kOhms resistance, ±25% tolerance, ±250ppm/°C temperature coefficient, and 1-turn top adjustment configuration. The substitute's 0.1W (1/10W) power rating is acceptable for applications where dissipation requirements do not exceed this lower threshold.

Mechanical Compatibility: The TC33X-1-204E maintains identical mounting type (surface mount), termination style (J Lead), and resistive material (cermet). Face dimensions are slightly reduced (0.150" x 0.142" versus 0.165" x 0.150"), which does not impact functional performance or PCB layout compatibility for standard applications.

Regulatory and Supply Status: The TC33X-1-204E holds active product status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory alignment. The substitute is available in higher inventory quantities (5748 pieces) compared to the obsolete original part (861 pieces).

Application Suitability: Substitution is appropriate for applications where the original 0.2W power rating is not a critical design constraint. Thermal analysis of the specific application circuit is required only if power dissipation approaches or exceeds 0.1W under normal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the Bourns TC33X-1-204E directly replace the TE Connectivity 3152W204P in existing designs?

A: Yes, for applications where power dissipation does not exceed 0.1W. The electrical specifications (resistance, tolerance, temperature coefficient, adjustment type) and mechanical parameters (surface mount, J Lead termination, cermet material) are equivalent. PCB layout compatibility is maintained despite minor face dimension reduction.

Q: What is the significance of the power rating difference (0.2W versus 0.1W)?

A: The substitute part is rated for lower power dissipation. If the original design operates with dissipation below 0.1W, the substitute performs identically. If dissipation approaches or exceeds 0.1W, thermal performance must be evaluated for the specific application circuit.

Q: Are there dimensional concerns with the slightly smaller face size of the TC33X-1-204E?

A: The TC33X-1-204E face dimensions (0.150" x 0.142") are smaller than the 3152W204P (0.165" x 0.150"). This reduction does not affect electrical performance or standard PCB layout compatibility. Verification is required only for applications with tight mechanical spacing constraints.

Q: What compliance certifications does the substitute part carry?

A: The Bourns TC33X-1-204E is ROHS3 compliant and REACH unaffected. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating and EAR99 export classification.

Q: Is the packaging format compatible between the original and substitute parts?

A: The 3152W204P packaging format is not specified in the original documentation. The TC33X-1-204E is supplied in Tape & Reel (TR) format. Packaging compatibility must be verified against specific manufacturing and assembly requirements.

Q: What is the series designation for the substitute part?

A: The Bourns TC33X-1-204E belongs to the Trimpot® TC33 - Open Frame series, which is distinct from the TE Connectivity 3150 series of the original part. Both series utilize identical cermet technology and 1-turn adjustment mechanisms.
