ST32TA204 Equivalent & Substitute Parts

Part Overview

The ST32TA204 is a 200 kOhms surface mount trimmer potentiometer rated at 0.125W (1/8W) with J Lead termination and cermet resistive material. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing production and maintenance applications. The ST32TA204 belongs to the ST-32 series of single-turn top-adjustment trimmers designed for precision resistance tuning in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ST32TA204 is determined by strict equivalence across the following critical parameters: resistance value (200 kOhms), power rating (0.125W), tolerance (±20%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top adjustment), resistive material (cermet), mounting type (surface mount), termination style (J Lead), and physical dimensions (3.40mm x 3.40mm square face). The ST-32ETA204 satisfies all these requirements and is therefore a direct equivalent substitute. Both parts maintain identical electrical and mechanical specifications within the ST-32 series platform.

Parameter Comparison

Engineering Selection Recommendations

The ST-32ETA204 is the direct equivalent substitute for the obsolete ST32TA204. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product status: the ST32TA204 is obsolete while the ST-32ETA204 is active and currently in production. Additionally, the ST-32ETA204 achieves ROHS3 compliance, whereas the ST32TA204 is RoHS non-compliant. For new designs and ongoing production requiring compliance with current environmental regulations, the ST-32ETA204 is the appropriate selection. Both parts maintain identical moisture sensitivity levels and REACH status, ensuring compatibility in equivalent application contexts.

Frequently Asked Questions (FAQ)

Q: Can the ST-32ETA204 be used as a direct replacement for the ST32TA204?

A: Yes. The ST-32ETA204 is a direct equivalent substitute. All electrical parameters (resistance, power rating, tolerance, temperature coefficient, number of turns) and mechanical specifications (mounting type, termination style, physical dimensions) are identical between the two parts.

Q: What is the primary reason to substitute the ST32TA204?

A: The ST32TA204 is classified as obsolete. The ST-32ETA204 is an active product from Nidec Components Corporation and is the recommended substitute for continued availability and production support.

Q: Are there any compliance differences between these parts?

A: Yes. The ST-32ETA204 is ROHS3 compliant, while the ST32TA204 is RoHS non-compliant. Both parts maintain identical REACH and ECCN classifications. For applications requiring RoHS compliance, the ST-32ETA204 is the appropriate choice.

Q: Do these parts have the same packaging options?

A: The ST32TA204 packaging information is not specified in the provided data. The ST-32ETA204 is available in Tape & Reel (TR) packaging. Packaging compatibility should be confirmed based on specific assembly requirements.

Q: Are the moisture sensitivity levels equivalent?

A: Yes. Both the ST32TA204 and ST-32ETA204 have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating identical moisture handling requirements.

Q: What is the physical footprint compatibility?

A: Both parts share identical physical dimensions: Square - 0.134" x 0.134" Face (3.40mm x 3.40mm). PCB layout and assembly tooling are compatible without modification.
