Key Parameters

Substitute Part Grouping Explanation

Substitution of the ST32TA101 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match:

• Resistance value: 100 Ohms
• Power rating: 0.125W (1/8W)
• 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
• Physical dimensions: Square - 0.134" x 0.134" Face (3.40mm x 3.40mm)
• Series compatibility: ST-32

The ST-32ETA101 meets all these criteria and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The ST-32ETA101 is the direct equivalent substitute for the obsolete ST32TA101. Both components are electrically and mechanically identical across all specified parameters, ensuring pin-for-pin and form-factor compatibility.

The ST-32ETA101 offers the advantage of active product status with current manufacturing support and ROHS3 compliance, addressing regulatory requirements for new designs and production continuity. The ST32TA101, classified as obsolete, is no longer actively manufactured.

Selection of the ST-32ETA101 is appropriate for applications requiring the ST32TA101 specification, with the added benefit of improved regulatory compliance and ongoing component availability.

Frequently Asked Questions (FAQ)

Q: Can the ST-32ETA101 be used as a direct replacement for the ST32TA101?

A: Yes. The ST-32ETA101 is electrically and mechanically equivalent to the ST32TA101. All critical parameters—resistance, power rating, tolerance, temperature coefficient, adjustment type, resistive material, mounting type, termination style, and physical dimensions—are identical. The components are pin-for-pin compatible and form-factor compatible.

Q: What is the difference between the ST32TA101 and ST-32ETA101?

A: The primary differences are manufacturer (Vishay Beyschlag/Draloric/BC Components versus Nidec Components Corporation), product status (obsolete versus active), and RoHS compliance (non-compliant versus ROHS3 compliant). All electrical and mechanical specifications are identical.

Q: Why is the ST32TA101 listed as obsolete?

A: The ST32TA101 has been discontinued by its original manufacturer. The ST-32ETA101 is the active equivalent part maintained by Nidec Components Corporation.

Q: Are there packaging differences between these parts?

A: The ST32TA101 packaging information is not specified in the available data. The ST-32ETA101 is supplied in Tape & Reel (TR) packaging. Confirm packaging requirements for your application.

Q: Does the RoHS compliance difference affect substitution?

A: The ST-32ETA101 is ROHS3 compliant, while the ST32TA101 is not. For applications subject to RoHS regulations, the ST-32ETA101 is the appropriate choice. For legacy systems not subject to RoHS requirements, both parts meet the electrical and mechanical specifications.

Q: What is the moisture sensitivity level for these components?

A: Both the ST32TA101 and ST-32ETA101 have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
