TE Connectivity 3152W103P Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3152W103P is a 10 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 3152W103P 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 from the original manufacturer is no longer available through standard distribution channels. Identifying functionally equivalent active alternatives ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 3152W103P is based on matching the following critical electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Resistance value: 10 kOhms
• Tolerance: ±25%
• Temperature coefficient: ±250ppm/°C
• Number of turns: 1 Turn
• Resistive material: Cermet

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Termination style: J Lead
• Adjustment type: Top Adjustment

Thermal Parameters (Must Meet or Exceed):

• Power rating: Minimum 0.2W (1/5W)

Physical Parameters (Compatible Range):

• Size/Dimension: Rectangular configuration with compatible face dimensions

The Bourns TC33X-1-103E meets all critical electrical parameters and mechanical interface requirements. While the TC33X-1-103E has a lower power rating (0.1W versus 0.2W), this represents a design consideration that must be evaluated within the specific application context. The TC33X-1-103E is an active product with current manufacturing status and full compliance certifications.

Engineering Selection Recommendations

Primary Substitute: Bourns TC33X-1-103E

The Bourns TC33X-1-103E is the recommended substitute for the obsolete TE Connectivity 3152W103P based on the following engineering criteria:

Product Status Alignment: The TC33X-1-103E is an active product with current manufacturing status, ensuring long-term availability and supply chain continuity. The original 3152W103P is classified as obsolete, making the TC33X-1-103E the appropriate alternative for new designs and production continuity.

Electrical Parameter Compatibility: All critical electrical parameters match exactly: 10 kOhms resistance, ±25% tolerance, ±250ppm/°C temperature coefficient, 1 Turn adjustment, and cermet resistive material. These parameters ensure functional equivalence in circuit operation.

Mechanical Interface Compatibility: The TC33X-1-103E maintains identical mechanical specifications: Surface Mount mounting type, J Lead termination style, and Top Adjustment configuration. Physical dimensions are compatible with the original design footprint.

Regulatory and Compliance Status: The TC33X-1-103E carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. Both components share identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Power Rating Consideration: The TC33X-1-103E has a lower power rating (0.1W) compared to the original 3152W103P (0.2W). This difference requires evaluation within the specific application thermal environment and duty cycle. Applications operating within 0.1W power dissipation limits are directly compatible without modification.

Frequently Asked Questions (FAQ)

Q: Can the Bourns TC33X-1-103E directly replace the TE Connectivity 3152W103P in existing designs?

A: The TC33X-1-103E is mechanically and electrically compatible for applications operating within its 0.1W power rating. The lower power rating must be verified against the actual power dissipation in the specific circuit. If the original design operates below 0.1W, direct substitution is valid. If the design requires the full 0.2W capability, thermal analysis is required to confirm the TC33X-1-103E is suitable.

Q: Are the physical dimensions compatible between these two parts?

A: The TC33X-1-103E has slightly smaller face dimensions (0.150" x 0.142" versus 0.165" x 0.150") but maintains rectangular configuration and J Lead termination. The smaller footprint is compatible with PCB layouts designed for the original 3152W103P, as the component occupies less space.

Q: What is the difference in tolerance and temperature stability between these parts?

A: Both components share identical tolerance (±25%) and temperature coefficient (±250ppm/°C) specifications. There is no difference in accuracy class or temperature stability performance between the two parts.

Q: Does the TC33X-1-103E meet current regulatory requirements?

A: Yes. The TC33X-1-103E is ROHS3 compliant and REACH Unaffected, meeting current regulatory standards for electronic component manufacturing and distribution. The original 3152W103P regulatory status is not specified in available documentation.

Q: What is the adjustment range for both components?

A: Both components feature 1 Turn adjustment with top adjustment access. The adjustment range is identical between the two parts, providing equivalent tuning capability.

Q: Are there packaging differences between the original and substitute part?

A: The TE Connectivity 3152W103P packaging is not specified in available documentation. The Bourns TC33X-1-103E is supplied in Tape & Reel (TR) packaging, which is standard for surface mount trimmer potentiometers and compatible with automated assembly processes.

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

A: Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage and handling requirements are identical between the two parts.
