Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4820P-1-102 is determined by the following critical parameters:

• Resistance value: 1kΩ
• Tolerance: ±2%
• Number of resistors: 10
• Circuit configuration: Isolated
• Power per element: 160mW
• Temperature coefficient: ±100ppm/°C
• Package type: 20-SOIC (0.220", 5.59mm Width)
• Pin count: 20
• Mounting: Surface Mount

The substitute part SOMC20031K00GEA from Vishay Dale meets all critical electrical and mechanical parameters. Both parts share identical resistance values, tolerance specifications, element count, circuit isolation, power ratings, temperature coefficients, and package dimensions. Physical compatibility is confirmed through matching package type, pin configuration, and mounting method.

Parameter Comparison

Engineering Selection Recommendations

The SOMC20031K00GEA from Vishay Dale is a direct functional equivalent to the 4820P-1-102. Both parts are active products with confirmed production status. The substitute part demonstrates superior operating temperature range capability (-55°C to 150°C versus -55°C to 125°C), providing extended thermal performance margin. The SOMC20031K00GEA carries ROHS3 compliance certification, while the 4820P-1-102 is RoHS non-compliant. For applications requiring RoHS compliance, the Vishay Dale part is the appropriate selection. Physical compatibility is confirmed through identical package dimensions and pin configuration. The substitute part's maximum seated height of 0.090" is within acceptable tolerance relative to the main part's 0.094" specification for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SOMC20031K00GEA be used as a direct replacement for 4820P-1-102 in existing designs?

A: Yes. Both parts share identical electrical specifications (1kΩ, ±2% tolerance, 160mW per element, ±100ppm/°C temperature coefficient) and mechanical compatibility (20-SOIC package, identical footprint dimensions, 20-pin configuration). No circuit redesign is required.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Bourns versus Vishay Dale), RoHS compliance status (non-compliant versus ROHS3 compliant), and operating temperature range (125°C maximum versus 150°C maximum). The substitute part offers extended thermal capability and improved environmental compliance.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 20-SOIC (0.220", 5.59mm Width) package with identical length and width dimensions of 0.540" x 0.220" (13.72mm x 5.59mm). The seated height differs slightly (0.094" versus 0.090"), which is within standard PCB assembly tolerances and does not affect compatibility.

Q: Which part should be selected for new designs?

A: Selection depends on compliance requirements. For RoHS-compliant applications, specify SOMC20031K00GEA. For applications without RoHS requirements, either part is acceptable based on availability and cost considerations.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the 4820P-1-102 and SOMC20031K00GEA are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
