Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SA105C103MAC is determined by the following critical parameters:

• Capacitance Value: Must be 10000 pF (no deviation permitted)
• Voltage Rating: Must be 50V or higher
• Temperature Coefficient: Must be X7R
• Operating Temperature Range: Must support -55°C ~ 125°C
• Mounting Type: Must be Through Hole
• Package / Case: Must be Axial
• Physical Dimensions: Must match 0.100" Dia x 0.170" L (2.54mm x 4.32mm)
• Lead Style: Must be Straight

The SA105C103KAA qualifies as a direct substitute based on these parameters. The primary difference is tolerance specification (±10% versus ±20%) and packaging format (Cut Tape versus Tape & Box), along with enhanced RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

SA105C103MAC is suitable for applications where RoHS non-compliant components are acceptable and ±20% tolerance meets circuit requirements. This part maintains active status with established supply availability.

SA105C103KAA is the preferred substitute when ROHS3 compliance is required or when tighter tolerance specification (±10%) is necessary for circuit performance. This substitute offers significantly higher inventory availability and identical electrical and mechanical characteristics within the critical substitution parameters.

Both parts are electrically and mechanically interchangeable within the specified parameter constraints. Selection between them depends on compliance requirements and tolerance specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can SA105C103KAA replace SA105C103MAC in existing designs?

A: Yes. Both parts share identical capacitance (10000 pF), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), and physical dimensions (0.100" Dia x 0.170" L). The SA105C103KAA offers tighter tolerance (±10% versus ±20%) and ROHS3 compliance, making it functionally compatible for direct substitution.

Q: What is the difference in tolerance between these parts?

A: SA105C103MAC specifies ±20% tolerance, while SA105C103KAA specifies ±10% tolerance. The tighter tolerance of SA105C103KAA provides greater capacitance accuracy and may be required in applications with strict circuit performance specifications.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0.100" Dia x 0.170" L (2.54mm x 4.32mm) in axial configuration with straight leads, ensuring identical PCB footprint and mounting compatibility.

Q: What is the significance of RoHS compliance difference?

A: SA105C103MAC is RoHS non-compliant, while SA105C103KAA is ROHS3 compliant. Applications subject to RoHS regulations or customer requirements for lead-free components must use SA105C103KAA.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Box versus Cut Tape) affects supply chain logistics and handling only. Electrical and mechanical performance remain identical between SA105C103MAC and SA105C103KAA.

Q: Which part should be selected for new designs?

A: SA105C103KAA is recommended for new designs due to ROHS3 compliance, tighter tolerance specification, and superior inventory availability (10843 Pcs versus 687 Pcs).
