TE Connectivity 3213X202M Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3213X202M is a 2 kOhms surface mount trimmer potentiometer rated at 0.125W (1/8W) with J Lead termination and top adjustment capability. This component features cermet resistive material construction with a 1-turn adjustment mechanism housed in a compact square package measuring 0.134" x 0.134" (3.40mm x 3.40mm).

The 3213X202M is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, field repairs, and design continuity for applications currently utilizing this component. Active equivalent models from alternative manufacturers provide identical electrical and mechanical specifications while maintaining current product status and supply availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 3213X202M is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a component to function as a direct substitute:

• Resistance value: 2 kOhms
• Power rating: 0.125W (1/8W)
• Tolerance: ±20%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1 Turn
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Surface Mount
• Termination style: J Lead
• Package dimensions: Square - 0.134" x 0.134" Face (3.40mm x 3.40mm)
• Moisture sensitivity level: MSL 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

The Nidec Components Corporation ST-32ETA202 and ST-32EA202 models satisfy all substitution criteria. Both parts are manufactured to identical specifications and are available in active product status. The primary distinction between these substitutes is packaging format: ST-32ETA202 is supplied in Tape & Reel configuration, while ST-32EA202 is supplied in Bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

Both Nidec Components Corporation models ST-32ETA202 and ST-32EA202 are direct functional equivalents to the obsolete TE Connectivity 3213X202M. Selection between these two substitute options is determined by procurement and assembly requirements rather than electrical or mechanical performance.

ST-32ETA202 (Tape & Reel Packaging): This configuration is suitable for automated assembly processes and high-volume production environments. Tape & Reel packaging provides component feeding compatibility with standard pick-and-place equipment. This option is recommended for manufacturing operations utilizing automated surface mount assembly.

ST-32EA202 (Bulk Packaging): This configuration is suitable for manual assembly, repair operations, and lower-volume applications. Bulk packaging provides flexibility for component selection and handling in non-automated environments. This option is recommended for field service, prototype development, and repair scenarios.

Both substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original component. Current inventory availability for both models supports immediate procurement without supply chain constraints.

Frequently Asked Questions (FAQ)

Q: Can the Nidec ST-32ETA202 and ST-32EA202 be used interchangeably with the TE Connectivity 3213X202M?

A: Yes. Both Nidec models are direct functional equivalents. All electrical parameters (resistance, power rating, tolerance, temperature coefficient) and mechanical specifications (package dimensions, termination style, adjustment type) are identical. The only difference is packaging format, which does not affect component performance or circuit operation.

Q: What is the difference between ST-32ETA202 and ST-32EA202?

A: The electrical and mechanical specifications are identical. The distinction is packaging format: ST-32ETA202 is supplied in Tape & Reel configuration for automated assembly, while ST-32EA202 is supplied in Bulk packaging for manual assembly and repair applications.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both ST-32ETA202 and ST-32EA202 are ROHS3 compliant, matching the compliance status of the original TE Connectivity 3213X202M.

Q: What is the Moisture Sensitivity Level for these components?

A: All three parts (original and both substitutes) are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these trimmer potentiometers be used in high-temperature applications?

A: The temperature coefficient specification of ±100ppm/°C applies to all three parts. This parameter defines the resistance change per degree Celsius within the operating temperature range. Specific operating temperature limits are not provided in the component specifications and must be determined from the manufacturer's detailed datasheet.

Q: What is the tolerance specification for these components?

A: All three parts carry a tolerance specification of ±20%, indicating the acceptable variation range from the nominal 2 kOhms resistance value.

Q: Are these components suitable for automated assembly?

A: The ST-32ETA202 in Tape & Reel packaging is designed for automated surface mount assembly. The ST-32EA202 in Bulk packaging is suitable for manual assembly and repair operations. The original TE Connectivity 3213X202M packaging format is not specified in the available documentation.
