Substitute Part Grouping Explanation

Substitution eligibility for the ST-5EP103 is determined by strict equivalence across all critical electrical and mechanical parameters:

Qualifying Parameters for Substitution:

• Resistance value: 10 kOhms
• Power rating: 0.25W (1/4W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 14
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Physical dimensions: Rectangular - 0.266" x 0.236" Face (6.75mm x 6.00mm)
• Moisture sensitivity level: 1 (Unlimited)
• Series: ST5

The ST-5ETP103 qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary difference is packaging format: ST-5EP103 is supplied in Bulk packaging, while ST-5ETP103 is supplied in Tape & Reel (TR) format. Both parts are manufactured by Nidec Components Corporation and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both ST-5EP103 and ST-5ETP103 are active products from Nidec Components Corporation with identical electrical and mechanical specifications. Selection between these parts should be based on procurement and assembly requirements:

ST-5EP103 (Bulk Packaging): Suitable for applications with lower volume requirements or when bulk inventory management is preferred.

ST-5ETP103 (Tape & Reel Packaging): Recommended for high-volume production environments utilizing automated pick-and-place assembly equipment. This part carries explicit ROHS3 compliance certification.

Both parts maintain REACH Unaffected status and EAR99 export classification. The identical HTSUS code (8533.40.8050) confirms tariff classification equivalence.

Frequently Asked Questions (FAQ)

Q: Can ST-5ETP103 be used as a direct replacement for ST-5EP103?
