ST5TW202 Equivalent & Substitute Parts

Part Overview

The ST5TW202 is a 2 kOhm, 0.25W surface mount trimmer potentiometer with Cermet resistive material, 14-turn top adjustment, and gull wing termination. Manufactured by Vishay Beyschlag/Draloric/BC Components, this part is classified as obsolete. Due to its discontinued status, identifying equivalent and substitute parts is essential for design continuity, production support, and long-term component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ST5TW202 is determined by the following critical parameters: resistance value (2 kOhms), power rating (0.25W), tolerance (±10%), temperature coefficient (±100ppm/°C), adjustment type (top adjustment), resistive material (Cermet), mounting type (surface mount), and termination style (gull wing). The number of turns and face dimensions are secondary considerations that may vary within acceptable mechanical and functional limits for equivalent operation.

The substitute parts identified below maintain all primary electrical specifications while offering improved availability and compliance status:

ST-5ETW202 (Nidec Components Corporation): Maintains identical electrical parameters, 14-turn configuration, and mechanical footprint. Active product status with RoHS3 compliance.

3269W-1-202G (Bourns Inc.): Maintains identical electrical parameters with 12-turn configuration and slightly larger face dimension (0.250" x 0.170"). Active product status with sealed design.

ST-5EW202 (Nidec Components Corporation): Maintains identical electrical parameters and 14-turn configuration with matching mechanical footprint. Active product status.

Parameter Comparison

Engineering Selection Recommendations

ST-5ETW202 is the primary recommended substitute. It maintains identical electrical and mechanical specifications with 14-turn configuration and matching footprint. Active product status ensures long-term availability. RoHS3 compliance supports modern manufacturing and regulatory requirements. Tape & Reel packaging accommodates automated assembly processes.

ST-5EW202 is an alternative substitute with identical specifications to the ST5TW202. Active product status provides availability assurance. Bulk packaging may require manual handling during assembly. Selection depends on packaging and supply chain requirements.

3269W-1-202G is a functional substitute with identical electrical parameters but differs in turn count (12 vs. 14) and face dimension (0.250" x 0.170" vs. 0.236" x 0.169"). The sealed design offers enhanced environmental protection. Moisture Sensitivity Level 2 requires controlled storage conditions. REACH Affected status may impose additional regulatory considerations. Selection requires mechanical compatibility verification for the larger footprint.

Frequently Asked Questions (FAQ)

Q: Can ST-5ETW202 be used as a direct replacement for ST5TW202?

A: Yes. ST-5ETW202 maintains all critical electrical parameters (2 kOhms, 0.25W, ±10% tolerance, ±100ppm/°C), identical turn count (14), and matching mechanical footprint (0.236" x 0.169"). Active product status and RoHS3 compliance provide regulatory and supply advantages.

Q: What is the difference between ST-5ETW202 and ST-5EW202?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: ST-5ETW202 is supplied in Tape & Reel format suitable for automated assembly, while ST-5EW202 is supplied in Bulk format. Selection depends on assembly process requirements.

Q: Can 3269W-1-202G replace ST5TW202 in all applications?

A: 3269W-1-202G maintains identical electrical specifications but differs in two parameters: turn count (12 vs. 14) and face dimension (0.250" x 0.170" vs. 0.236" x 0.169"). Applications requiring precise adjustment resolution or constrained PCB layout may be affected. Mechanical compatibility must be verified before substitution.

Q: What are the compliance differences between substitute parts?

A: ST-5ETW202 is RoHS3 compliant with REACH Unaffected status. ST-5EW202 compliance status is not specified. 3269W-1-202G is RoHS non-compliant with REACH Affected status, requiring additional regulatory evaluation for new designs.

Q: How does Moisture Sensitivity Level affect part selection?

A: ST5TW202, ST-5ETW202, and ST-5EW202 have MSL 1 (Unlimited), requiring no special storage conditions. 3269W-1-202G has MSL 2 (1 Year), requiring controlled humidity storage and limiting shelf life. Selection depends on supply chain and storage capabilities.

Q: Are there packaging considerations for automated assembly?

A: ST-5ETW202 and 3269W-1-202G are supplied in Tape & Reel format, compatible with pick-and-place equipment. ST-5EW202 is supplied in Bulk format, requiring manual handling or custom tape preparation. Assembly process capabilities determine optimal packaging selection.
