ST32TA202 Equivalent & Substitute Parts

Part Overview

The ST32TA202 is a 2 kOhms surface mount trimmer potentiometer with 0.125W power rating, J lead termination, and top adjustment capability. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The ST-32 series trimmers are used in precision analog circuits requiring adjustable resistance values with cermet resistive elements and single-turn adjustment mechanisms.

Substitute Part Grouping Explanation

Substitute parts for the ST32TA202 are qualified based on strict electrical and mechanical parameter matching within the ST-32 series. The following parameters determine substitution eligibility:

• Resistance value: 2 kOhms (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Tolerance: ±20% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 1 (exact match required)
• Adjustment type: Top Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Surface Mount (exact match required)
• Termination style: J Lead (exact match required)
• Physical dimensions: 3.40mm x 3.40mm square face (exact match required)
• Moisture sensitivity level: 1 (exact match required)

All identified substitutes maintain identical electrical performance and mechanical compatibility with the original ST32TA202 specification.

Parameter Comparison

Engineering Selection Recommendations

Both ST-32EA202 and ST-32ETA202 are active product alternatives to the obsolete ST32TA202. Selection between these substitutes is determined by packaging requirements and regulatory compliance needs.

The ST-32ETA202 is the preferred substitute for new designs and production applications requiring RoHS3 compliance. This part is available in Tape & Reel packaging, suitable for automated assembly processes, and maintains full regulatory compliance with current environmental standards.

The ST-32EA202 serves as an alternative where bulk packaging is acceptable and RoHS compliance is not a design requirement. Both parts are manufactured by Nidec Components Corporation and provide identical electrical and mechanical performance to the original ST32TA202.

Frequently Asked Questions (FAQ)

Q: Can ST-32EA202 and ST-32ETA202 be used interchangeably with ST32TA202?

A: Both parts are electrically and mechanically equivalent to ST32TA202. The primary differences are product status (active vs. obsolete), packaging format, and RoHS compliance. Selection depends on application requirements and assembly process specifications.

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

A: Both parts have identical electrical specifications and physical dimensions. The ST-32EA202 is supplied in bulk packaging, while ST-32ETA202 is supplied in Tape & Reel format. The ST-32ETA202 carries ROHS3 compliance certification; RoHS status for ST-32EA202 is not specified in available documentation.

Q: Why is the original ST32TA202 marked as obsolete?

A: The ST32TA202 is no longer in active production. Nidec Components Corporation has transitioned to the ST-32EA202 and ST-32ETA202 variants as the current product line for this trimmer potentiometer specification.

Q: Are there any performance differences between the substitute parts and the original?

A: No. All three parts maintain identical resistance value, power rating, tolerance, temperature coefficient, adjustment mechanism, resistive material composition, and physical dimensions. Electrical performance and circuit behavior are equivalent.

Q: Which substitute should be selected for new product designs?

A: The ST-32ETA202 is recommended for new designs due to active product status, ROHS3 compliance, and Tape & Reel packaging compatibility with modern automated assembly equipment.

Q: What packaging considerations apply to these substitutes?

A: ST-32EA202 is supplied in bulk packaging for manual or semi-automated assembly. ST-32ETA202 is supplied in Tape & Reel format, optimized for high-volume automated pick-and-place assembly processes.
