Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SA205C473MAC is determined by the following critical parameters:

• Capacitance Value: Must be 0.047 µF (exact match required)
• Voltage Rating: Must be 50V or higher (equal or greater)
• Temperature Coefficient: Must be X7R (ensures stable performance across operating range)
• Mounting Type: Must be Through Hole with Axial package configuration
• Lead Style: Must be Straight leads
• Operating Temperature Range: Must support -55°C ~ 125°C minimum

The SA105C473KAA qualifies as a substitute based on these parameters. While it differs in tolerance specification (±10% versus ±20%) and physical dimensions (0.170" L versus 0.260" L), these variations remain within acceptable substitution criteria for general-purpose applications where the tighter tolerance and compact form factor provide design advantages.

Parameter Comparison

Engineering Selection Recommendations

SA205C473MAC is appropriate for applications where RoHS non-compliance is acceptable and standard tolerance (±20%) meets circuit requirements. This part maintains active production status with established supply availability.

SA105C473KAA is the preferred substitute when ROHS3 compliance is required for end-product certification or regulatory requirements. The tighter tolerance specification (±10%) provides improved capacitance accuracy for precision applications. The compact form factor (0.170" L versus 0.260" L) accommodates space-constrained PCB layouts while maintaining identical electrical performance across the operating temperature range. Both parts share identical capacitance, voltage rating, temperature coefficient, and operating temperature specifications, ensuring direct functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can SA105C473KAA replace SA205C473MAC in existing designs?

A: Yes. Both parts share identical capacitance (0.047 µF), voltage rating (50V), temperature coefficient (X7R), and operating temperature range (-55°C ~ 125°C). The primary differences are physical length (0.170" versus 0.260"), tolerance (±10% versus ±20%), and RoHS compliance status. PCB layout must accommodate the shorter component length.

Q: What is the significance of the tolerance difference between ±20% and ±10%?

A: Tolerance defines the acceptable deviation from the nominal capacitance value. SA105C473KAA's ±10% tolerance provides tighter capacitance accuracy compared to SA205C473MAC's ±20% tolerance. For general-purpose applications, both tolerances are functionally equivalent. Precision circuits requiring strict capacitance values benefit from the ±10% specification.

Q: Does the packaging difference (Tape & Box versus Cut Tape) affect component performance?

A: No. Packaging type affects handling, storage, and automated assembly processes but does not alter electrical or mechanical performance. Tape & Box (TB) packaging suits manual handling and smaller production volumes. Cut Tape (CT) packaging optimizes automated pick-and-place assembly for high-volume manufacturing.

Q: Are there compliance implications when substituting these parts?

A: Yes. SA105C473KAA is ROHS3 compliant while SA205C473MAC is RoHS non-compliant. If your end product requires RoHS certification, SA105C473KAA is the appropriate selection. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: What is the physical space impact of using SA105C473KAA instead of SA205C473MAC?

A: SA105C473KAA is 0.090" shorter (0.170" L versus 0.260" L). This compact form factor reduces PCB footprint length, enabling tighter component spacing in space-constrained designs. The diameter remains identical at 0.100".
