Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4820P-2-103LF is determined by strict equivalence across the following critical parameters:

• Resistance value: 10kΩ
• Tolerance: ±2%
• Number of resistors: 19
• Circuit configuration: Bussed
• Power per element: 80mW
• Temperature coefficient: ±100ppm/°C
• Package type: 20-SOIC (0.220", 5.59mm Width)
• Pin count: 20
• Mounting technology: Surface Mount
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The SOMC200110K0GEA from Vishay Dale meets all these criteria, establishing it as a direct functional equivalent. Both components share identical electrical specifications and mechanical footprints, enabling direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the 4820P-2-103LF and SOMC200110K0GEA are active production components with ROHS3 compliance and MSL 1 rating. The Vishay Dale SOMC200110K0GEA provides an extended operating temperature range to 150°C compared to the Bourns 4820P-2-103LF at 125°C, and a marginally lower seated height of 0.090" versus 0.094". These differences do not affect functional equivalence for standard applications. Selection between these parts should be based on supply chain availability, lead time requirements, and specific thermal environment demands of the application.

Frequently Asked Questions (FAQ)

Q: Can SOMC200110K0GEA replace 4820P-2-103LF in existing designs?

A: Yes. Both components share identical electrical specifications (10kΩ, ±2%, 80mW per element, ±100ppm/°C) and mechanical footprints (20-SOIC, 0.220" width). Direct substitution is supported without circuit modification.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer (Bourns vs. Vishay Dale), operating temperature range (125°C vs. 150°C maximum), and seated height (0.094" vs. 0.090"). Electrical performance and package dimensions are identical.

Q: Are both parts suitable for automotive applications?

A: The 4820P-2-103LF carries AEC-Q200 qualification. The SOMC200110K0GEA does not list automotive qualification in the provided specifications. Automotive applications requiring AEC-Q200 certification should use the 4820P-2-103LF.

Q: Do these parts require different PCB layouts?

A: No. Both components use the 20-SOIC package with identical 0.540" x 0.220" footprints and 20-pin configurations. PCB layouts are fully compatible.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 indicates unlimited moisture sensitivity level, meaning these components do not require special moisture control during storage or handling, simplifying logistics and inventory management.
