Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SM-3TA103 is determined by strict alignment of the following electrical and mechanical parameters:

• Resistance value: 10 kOhms
• Power rating: 0.125W (1/8W)
• Tolerance: ±20%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 11
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Surface Mount
• Termination style: J Lead
• RoHS3 compliance status
• Moisture sensitivity level: 1 (Unlimited)

The Bourns 3223J-1-103E meets all electrical specifications and regulatory requirements. Minor dimensional variation in the face profile (rectangular 0.154" x 0.125" versus square 0.154" x 0.154") does not affect electrical performance or standard PCB footprint compatibility for J Lead surface mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SM-3TA103 and 3223J-1-103E maintain Active product status with full RoHS3 compliance and unlimited moisture sensitivity ratings. Selection between these components should be based on supply chain availability, lead time requirements, and inventory positioning. The Bourns 3223J-1-103E currently maintains higher inventory levels (5622 pcs versus 662 pcs), which may influence procurement decisions for volume applications. Both components satisfy identical electrical and regulatory requirements for direct substitution in surface mount trimmer potentiometer applications.

Frequently Asked Questions (FAQ)

Q: Can the 3223J-1-103E replace the SM-3TA103 in existing designs?

A: Yes. Both components share identical electrical specifications (10 kOhms, 0.125W, ±20% tolerance, ±100ppm/°C temperature coefficient, 11-turn adjustment) and J Lead termination. The minor dimensional difference in face profile does not affect PCB footprint compatibility or electrical performance.

Q: What is the significance of the face dimension difference?

A: The SM-3TA103 features a square face (0.154" x 0.154"), while the 3223J-1-103E has a rectangular face (0.154" x 0.125"). This variation does not impact J Lead positioning or standard surface mount assembly processes. Both components are compatible with equivalent PCB layouts.

Q: Are there compliance differences between these parts?

A: Both components are RoHS3 compliant with MSL 1 (Unlimited) ratings. The SM-3TA103 carries REACH Unaffected status, while the 3223J-1-103E is REACH Affected. Both share identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Q: Which component should be selected for new designs?

A: Selection should be based on supply availability and procurement lead times. Both components meet identical functional and regulatory requirements. The Bourns 3223J-1-103E offers higher current inventory availability.

Q: Are the adjustment mechanisms identical?

A: Yes. Both components feature 11-turn side adjustment with cermet resistive material and identical temperature coefficient performance (±100ppm/°C).
