Key Parameters

Substitute Part Grouping Explanation

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

Primary Substitution Criteria:

• Resistance value: 10kΩ
• Tolerance: ±2%
• Circuit topology: Bussed configuration
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: minimum -55°C to 125°C
• Mounting type: Surface mount
• Package footprint compatibility: 20-SOIC (0.220", 5.59mm Width)

Secondary Compatibility Factors:

• Number of resistor elements: 19 (pin-for-pin compatibility)
• Power dissipation per element: 80mW or greater
• MSL rating: 1 (Unlimited)

Parts meeting all primary criteria and maintaining equivalent or superior secondary specifications are classified as direct substitutes. The 767161103GP presents a functional alternative with different pin count and element quantity but maintains core electrical parameters. The SOMC200110K0GEA provides pin-for-pin equivalence with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

SOMC200110K0GEA (Vishay Dale) is the primary equivalent substitute for the 4820P-2-103. This part provides pin-for-pin compatibility with identical resistor count (19 elements), matching package dimensions (20-SOIC), and equivalent electrical specifications. The extended operating temperature range (-55°C to 150°C) provides additional thermal margin. ROHS3 compliance offers environmental regulatory advantage over the non-compliant main part. Tape & Reel packaging matches the original specification.

767161103GP (CTS Resistor Products) is a functional alternative for applications where pin count flexibility exists. This part maintains core electrical parameters (10kΩ, ±2%, ±100ppm/°C, bussed topology) but differs in package configuration (16-SOIC with 15 resistor elements). The higher power rating per element (100mW versus 80mW) provides thermal headroom. ROHS3 compliance and active product status support long-term availability. Tube packaging differs from the original Tape & Reel format and requires PCB layout modification due to different pin assignments.

Both substitutes maintain the required operating temperature floor of -55°C and preserve bussed circuit topology essential for network functionality. Selection between alternatives depends on PCB layout constraints and packaging logistics requirements.

Frequently Asked Questions (FAQ)

Q: Can the 767161103GP directly replace the 4820P-2-103 on an existing PCB?

A: No. The 767161103GP uses a 16-SOIC package with 15 resistor elements, while the 4820P-2-103 uses a 20-SOIC package with 19 elements. Pin assignments differ, requiring PCB layout modification. This part is suitable only for new designs or redesigned boards.

Q: Is the SOMC200110K0GEA a drop-in replacement?

A: Yes, for PCB compatibility. The SOMC200110K0GEA maintains identical package type (20-SOIC), pin count (20), and resistor element count (19). Electrical specifications match the original part. Tape & Reel packaging aligns with standard manufacturing processes.

Q: What are the key electrical parameters that must remain constant during substitution?

A: Resistance value (10kΩ), tolerance (±2%), circuit topology (bussed), temperature coefficient (±100ppm/°C), and minimum operating temperature range (-55°C to 125°C) are non-negotiable. Power per element must equal or exceed 80mW. Package footprint and pin count must match the application requirements.

Q: Why does the 4820P-2-103 show RoHS non-compliance while substitutes are ROHS3 compliant?

A: RoHS compliance status reflects manufacturing process and material composition at the time of specification. ROHS3-compliant alternatives meet current environmental regulations while maintaining equivalent electrical performance. Compliance status should be evaluated against application requirements and regional regulations.

Q: Are there temperature range differences that affect part selection?

A: The SOMC200110K0GEA extends the upper operating limit to 150°C compared to 125°C for the main part and 767161103GP. For applications operating within -55°C to 125°C, all three parts are functionally equivalent. Extended temperature applications benefit from the Vishay Dale part.

Q: What packaging format differences exist between these parts?

A: The 4820P-2-103 and SOMC200110K0GEA are supplied in Tape & Reel format, suitable for automated assembly. The 767161103GP is supplied in Tube format, requiring manual handling or alternative feeder systems. Packaging selection impacts manufacturing workflow and cost structure.
