Key Parameters

Substitute Part Grouping Explanation

Substitution of the ST32ETG202BC is determined by strict equivalence across the following critical parameters:

• Resistance value: 2 kOhms
• Power rating: 0.125W (1/8W)
• Tolerance: ±20%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1.0
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Surface Mount
• Termination style: J Lead
• Moisture sensitivity level: MSL 1

The substitute part ST-32ETG202 manufactured by Nidec Components Corporation meets all these electrical and mechanical specifications, confirming functional equivalence despite minor dimensional variations and different product status classifications.

Parameter Comparison

Engineering Selection Recommendations

The ST-32ETG202 manufactured by Nidec Components Corporation is the direct functional equivalent for the obsolete ST32ETG202BC. Selection of the Nidec substitute is supported by:

• Complete electrical parameter equivalence across all specified values
• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance, addressing regulatory requirements not met by the original part
• Identical core specifications for resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics
• Equivalent moisture sensitivity classification and termination style

The minor dimensional variation (0.142" x 0.138" versus 0.185" x 0.142") remains within acceptable tolerances for surface mount applications utilizing J Lead termination and does not affect functional performance or circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can ST-32ETG202 be used as a direct replacement for ST32ETG202BC?

A: Yes. Both parts share identical electrical specifications including 2 kOhms resistance, 0.125W power rating, ±20% tolerance, ±100ppm/°C temperature coefficient, 1.0 turn side adjustment, cermet resistive material, surface mount configuration, and J Lead termination. The substitute is functionally equivalent.

Q: What is the significance of the product status difference?

A: The original ST32ETG202BC is obsolete, meaning it is no longer manufactured or supported by Vishay. The ST-32ETG202 is active, ensuring continued availability, technical support, and supply chain reliability for new designs and production requirements.

Q: Does RoHS compliance affect substitution?

A: The ST-32ETG202 is ROHS3 compliant while the original is non-compliant. For applications subject to RoHS regulations, the substitute provides regulatory alignment. For legacy systems without RoHS requirements, both parts remain functionally equivalent.

Q: Are there packaging differences?

A: The ST-32ETG202 is supplied in Tape & Reel (TR) packaging. Packaging format does not affect component performance or electrical characteristics, only handling and assembly logistics.

Q: What are the dimensional tolerances for substitution?

A: The ST-32ETG202 measures 0.142" x 0.138" (3.60mm x 4.60mm) compared to the original 0.185" x 0.142" (4.70mm x 3.60mm). Both maintain rectangular form factors suitable for surface mount J Lead applications. Verify PCB layout accommodates the substitute dimensions before implementation.
