• Tolerance: ±20%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Package dimensions: 5.00mm x 4.50mm rectangular form factor
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The ST-4ETB201 manufactured by Nidec Components Corporation meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent despite differences in series designation and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The ST-4ETB201 is the designated manufacturer-recommended substitute for the SMUB201PET. Both components are ROHS3 compliant and carry identical electrical specifications and mechanical form factors. The primary distinction is product status: the SMUB201PET is obsolete while the ST-4ETB201 maintains active production status, ensuring long-term availability and supply chain continuity. Both components carry ECCN EAR99 classification and identical HTSUS codes (8533.40.8050), confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the ST-4ETB201 be used as a direct replacement for the SMUB201PET in existing designs?

A: Yes. The ST-4ETB201 matches all electrical parameters (200 Ohms, 0.25W, ±20% tolerance, ±100ppm/°C temperature coefficient), mechanical specifications (5.00mm x 4.50mm rectangular package, gull wing termination, top adjustment), and compliance certifications (ROHS3, MSL 1). No circuit redesign is required.

Q: What is the primary reason for substitution?

A: The SMUB201PET is classified as obsolete. The ST-4ETB201 is an active product with confirmed ongoing manufacturing and supply availability.

Q: Are there packaging differences between these parts?

A: The SMUB201PET is supplied in Cut Tape (CT) format while the ST-4ETB201 is supplied in Tape & Reel (TR) format. Both packaging formats are compatible with standard surface mount assembly processes. Tape & Reel packaging is standard for high-volume production environments.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and share identical ECCN and HTSUS classifications.

Q: Are the electrical characteristics identical?

A: Yes. Resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, and resistive material are identical across both parts.
