ST7TA202 Equivalent & Substitute Parts

Part Overview

The ST7TA202 is a 2 kOhms, 0.25W surface mount trimmer potentiometer with J Lead termination and top adjustment capability. Manufactured by Vishay Beyschlag/Draloric/BC Components, this component features a cermet resistive element and is rated for 3-turn adjustment with ±20% tolerance. The product is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring this specific electrical and mechanical configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ST7TA202 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part ST-7ETA202 qualifies as a direct equivalent based on the following criteria:

• Identical resistance value: 2 kOhms
• Identical power rating: 0.25W (1/4W)
• Identical tolerance: ±20%
• Identical temperature coefficient: ±100ppm/°C
• Identical number of turns: 3
• Identical adjustment type: Top Adjustment
• Identical resistive material: Cermet
• Identical mounting type: Surface Mount
• Identical termination style: J Lead
• Identical physical dimensions: Rectangular - 0.252" x 0.240" Face (6.40mm x 6.10mm)
• Identical moisture sensitivity level: 1 (Unlimited)

Engineering Selection Recommendations

The ST-7ETA202 manufactured by Nidec Components Corporation is the direct equivalent substitute for the obsolete ST7TA202. Selection of the ST-7ETA202 is supported by:

• Complete electrical parameter equivalence across all specified values
• Identical mechanical configuration and physical dimensions enabling direct PCB footprint compatibility
• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance providing regulatory advantage over the non-compliant original part
• Equivalent moisture sensitivity rating and environmental specifications

The ST-7ETA202 is suitable for direct replacement in applications where the ST7TA202 was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the ST-7ETA202 be used as a direct replacement for ST7TA202 in existing designs?

A: Yes. The ST-7ETA202 is electrically and mechanically equivalent to the ST7TA202 across all specified parameters, including resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, and physical dimensions. PCB footprint compatibility is maintained.

Q: What is the primary advantage of selecting ST-7ETA202 over ST7TA202?

A: The ST-7ETA202 is an active product with current manufacturing support, whereas the ST7TA202 is obsolete. Additionally, the ST-7ETA202 is ROHS3 compliant, providing regulatory compliance benefits.

Q: Are there packaging differences between these parts?

A: The ST7TA202 packaging information was not specified in the original documentation. The ST-7ETA202 is available in Tape & Reel (TR) packaging format.

Q: Do these parts have identical environmental ratings?

A: Yes. Both parts share identical moisture sensitivity level (MSL 1 - Unlimited), REACH status (REACH Unaffected), and ECCN/HTSUS classifications.

Q: What parameters must remain identical for substitution to be valid?

A: All electrical parameters (resistance, power rating, tolerance, temperature coefficient), mechanical parameters (number of turns, adjustment type, resistive material, termination style, physical dimensions), and mounting configuration must be identical for direct substitution.
