Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 4820P-1-104 is determined by the following critical parameters:

• Resistance value: 100k Ohm
• Tolerance: ±2%
• Number of resistors: 10
• Circuit configuration: Isolated
• Power per element: 160mW
• Temperature coefficient: ±100ppm/°C
• Package: 20-SOIC (0.220", 5.59mm Width)
• Pin count: 20
• Mounting type: Surface Mount

The Vishay Dale SOMC2003100KGEA meets all these core electrical and mechanical parameters, making it a direct functional equivalent. Both parts share identical resistance specifications, tolerance, element count, circuit isolation, power rating, temperature coefficient, and physical packaging dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns 4820P-1-104 and Vishay Dale SOMC2003100KGEA are active products with identical electrical specifications and mechanical compatibility. The Vishay Dale SOMC2003100KGEA offers an extended operating temperature range to 150°C compared to the Bourns part at 125°C, and achieves ROHS3 compliance versus the non-compliant status of the Bourns component. Selection between these parts should be based on specific application requirements regarding temperature range and regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Dale SOMC2003100KGEA be used as a direct replacement for the Bourns 4820P-1-104?

A: Yes. Both parts share identical resistance values (100k Ohm), tolerance (±2%), element count (10), circuit isolation, power rating (160mW), temperature coefficient (±100ppm/°C), and 20-SOIC package dimensions. Physical dimensions and pin configurations are compatible for direct PCB substitution.

Q: What is the difference in operating temperature range between these parts?

A: The Bourns 4820P-1-104 operates from -55°C to 125°C, while the Vishay Dale SOMC2003100KGEA operates from -55°C to 150°C. Applications requiring operation above 125°C must use the Vishay Dale part.

Q: Are there compliance differences between these parts?

A: The Bourns 4820P-1-104 is RoHS non-compliant. The Vishay Dale SOMC2003100KGEA is ROHS3 compliant. Applications subject to RoHS regulations must use the Vishay Dale component.

Q: Are the physical dimensions identical?

A: Both parts use 20-SOIC (0.220", 5.59mm Width) packaging with identical length and width dimensions of 0.540" L x 0.220" W (13.72mm x 5.59mm). The seated height differs slightly: Bourns at 0.094" (2.40mm) and Vishay Dale at 0.090" (2.29mm). This minimal difference does not affect PCB layout compatibility.

Q: What packaging formats are available for these parts?

A: Both the Bourns 4820P-1-104 and Vishay Dale SOMC2003100KGEA are supplied in Tape & Reel (TR) format for automated assembly processes.
