Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 3152W202P is based on electrical and mechanical parameter alignment within the trimmer potentiometer category. The critical substitution criteria are:

Electrical Parameters (Must Match):

• Resistance value: 2 kOhms
• Tolerance: ±25%
• Temperature Coefficient: ±250ppm/°C
• Number of Turns: 1.0
• Adjustment Type: Top Adjustment

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Termination Style: J Lead
• Resistive Material: Cermet

Allowable Variation:

• Power Rating: The substitute part may operate at a lower power rating (0.1W) provided the application does not exceed this reduced specification. The 3152W202P operates at 0.2W; substitutes rated at 0.1W are acceptable for applications requiring ≤0.1W dissipation.
• Physical Dimensions: Minor dimensional differences are acceptable provided the substitute maintains surface mount compatibility and J Lead termination within standard PCB footprint tolerances.

The Bourns TC33X-1-202E meets all critical electrical parameters and mechanical mounting requirements, with the exception of reduced power rating (0.1W versus 0.2W).

Parameter Comparison

Engineering Selection Recommendations

The Bourns TC33X-1-202E serves as the primary substitute for the obsolete TE Connectivity 3152W202P based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters align, including resistance value, tolerance, temperature coefficient, and adjustment characteristics. The substitute maintains identical functional performance in trimmer potentiometer applications requiring 2 kOhms adjustment capability.

Mechanical Compatibility: Surface mount J Lead termination is identical, ensuring PCB footprint compatibility. Dimensional reduction (0.150" x 0.142" versus 0.165" x 0.150") presents no mechanical constraint for standard surface mount assembly processes.

Product Status: The TC33X-1-202E is classified as active with current manufacturing status, ensuring long-term availability and supply chain continuity. The 3152W202P is obsolete and subject to inventory depletion.

Compliance and Certifications: The TC33X-1-202E is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Power Rating Consideration: The substitute operates at 0.1W (1/10W) versus the original 0.2W (1/5W). Selection of the TC33X-1-202E is appropriate for applications where power dissipation does not exceed 0.1W. Applications requiring the full 0.2W rating require alternative evaluation.

Frequently Asked Questions (FAQ)

Q: Can the Bourns TC33X-1-202E directly replace the TE Connectivity 3152W202P in existing designs?

A: Direct replacement is possible provided the application power dissipation does not exceed 0.1W. The electrical parameters (resistance, tolerance, temperature coefficient) and mechanical mounting (surface mount J Lead) are identical. The reduced power rating is the only limiting factor.

Q: What is the impact of the reduced power rating (0.1W versus 0.2W)?

A: The substitute part is rated for maximum 0.1W dissipation. If the original design operates below 0.1W, the substitute performs identically. If the design requires dissipation between 0.1W and 0.2W, the substitute may experience thermal stress and reduced operational life. Application power analysis is required to confirm compatibility.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: The substitute dimensions (0.150" x 0.142") are slightly smaller than the original (0.165" x 0.150"). Both parts use identical J Lead termination and surface mount technology. Standard PCB footprints designed for the 3152W202P accommodate the TC33X-1-202E without modification.

Q: What is the availability status of each part?

A: The TE Connectivity 3152W202P is obsolete with 704 pieces in current inventory. The Bourns TC33X-1-202E is active with 5,768 pieces in current inventory, providing superior long-term supply assurance.

Q: Are there compliance differences between the two parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications. The TC33X-1-202E includes RoHS3 compliance and REACH unaffected status, meeting current regulatory standards. The 3152W202P does not specify these certifications.

Q: What adjustment characteristics are preserved in the substitute?

A: Both parts feature 1.0 turn top adjustment with cermet resistive material and ±25% tolerance. Adjustment resolution and control characteristics are identical.
