Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SM-3TA201 are identified based on matching the following critical parameters:

• Resistance value: 200 Ohms
• 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
• Moisture sensitivity level: MSL 1

The substitute part 3223J-1-201E from Bourns Inc. meets all these electrical and mechanical criteria, making it a direct functional equivalent for the SM-3TA201.

Parameter Comparison

Engineering Selection Recommendations

Both the SM-3TA201 and 3223J-1-201E are active production components with ROHS3 compliance and MSL 1 rating. The parts are electrically identical across all specified parameters. The primary difference is the face dimension: the SM-3TA201 has a square footprint (3.90mm x 3.90mm), while the 3223J-1-201E has a rectangular footprint (3.90mm x 3.18mm). Selection between these parts depends on PCB layout constraints and available board space. Both parts are suitable for applications requiring a 200 Ohm surface mount trimmer potentiometer with cermet resistive material and side adjustment capability.

Frequently Asked Questions (FAQ)

Q: Can the 3223J-1-201E replace the SM-3TA201 in all applications?

A: The 3223J-1-201E is electrically equivalent to the SM-3TA201 across all specified parameters. However, the rectangular footprint (3.90mm x 3.18mm) differs from the square footprint (3.90mm x 3.90mm) of the SM-3TA201. PCB layout compatibility must be verified before substitution.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and carry MSL 1 rating. The SM-3TA201 is REACH Unaffected, while the 3223J-1-201E is REACH Affected. Regulatory requirements for your application should be considered during part selection.

Q: What are the key electrical parameters that define substitutability?

A: The critical parameters for substitution are: 200 Ohm resistance, 0.125W power rating, ±20% tolerance, ±100ppm/°C temperature coefficient, 11-turn configuration, cermet material, side adjustment type, and J lead termination. Parts matching all these specifications are functionally equivalent.

Q: Do these parts have the same packaging?

A: Both parts are supplied in Tape & Reel (TR) packaging. The physical footprint dimensions differ as noted in the parameter comparison table.
