Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ST32TG102 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1 kOhms
• Power rating: 0.125W (1/8W)
• Tolerance: ±20%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Surface Mount
• Termination style: J Lead
• Series classification: ST-32

The ST-32ETG102 meets all electrical and mechanical requirements for direct substitution. Minor dimensional variations within the rectangular form factor do not affect functional compatibility or PCB layout constraints for this component category.

Parameter Comparison

Engineering Selection Recommendations

The ST-32ETG102 is the direct functional equivalent for the obsolete ST32TG102. Selection between these parts should be based on the following criteria:

ST-32ETG102 is preferred when:

• RoHS3 compliance is required for new designs or regulatory adherence
• Active product status and ongoing manufacturer support are necessary
• Tape & Reel packaging is compatible with assembly processes
• Long-term component availability is a design consideration

ST32TG102 remains applicable when:

• Existing inventory supports production requirements
• Legacy system maintenance does not impose compliance constraints
• Bulk packaging meets assembly workflow specifications

Both parts are electrically and mechanically interchangeable within the ST-32 series classification.

Frequently Asked Questions (FAQ)

Q: Can ST-32ETG102 replace ST32TG102 in existing designs? A: Yes. Both parts share identical electrical specifications (1 kOhms, 0.125W, ±20% tolerance, ±100ppm/°C temperature coefficient) and mechanical characteristics (cermet material, J lead termination, side adjustment, surface mount). The primary difference is product status and RoHS compliance.

Q: What are the dimensional differences between these parts? A: ST32TG102 has a rectangular face of 0.185" x 0.142" (4.70mm x 3.60mm). ST-32ETG102 has a rectangular face of 0.142" x 0.138" (3.60mm x 4.60mm). Both maintain the same J lead termination and side adjustment interface, ensuring PCB compatibility.

Q: Does packaging affect electrical performance? A: No. ST32TG102 is supplied in bulk packaging, while ST-32ETG102 is supplied in Tape & Reel (TR) format. Packaging affects handling and assembly logistics only, not component function or electrical characteristics.

Q: Is RoHS compliance a functional requirement for substitution? A: RoHS compliance is a regulatory and supply chain consideration, not an electrical or mechanical requirement. ST32TG102 is RoHS non-compliant, while ST-32ETG102 is ROHS3 compliant. Selection depends on applicable regulations and customer requirements.

Q: Are there any circuit design considerations when switching between these parts? A: No. Both parts operate identically within the specified electrical parameters. No circuit modifications, PCB layout adjustments, or firmware changes are required for substitution.
