MA205C473KAC Equivalent & Substitute Parts

Part Overview

The MA205C473KAC is a 0.047 µF ceramic capacitor rated at 50V with X7R temperature coefficient, manufactured by KYOCERA AVX in the Ceralam® MA series. This axial through-hole component is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active in production with 727 units in stock. Identifying equivalent substitute parts is necessary when the primary part becomes unavailable or when alternative packaging or compliance requirements must be met.

Substitute Part Grouping Explanation

Substitution eligibility for the MA205C473KAC is determined by the following critical parameters:

• Capacitance value: 0.047 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 50V minimum (equal or higher acceptable)
• Temperature coefficient: X7R (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Axial (exact match required)
• Lead style: Straight (exact match required)

The SA105C473KAA meets all substitution criteria. Both parts are manufactured by KYOCERA AVX, share identical electrical specifications, and are housed in axial through-hole packages with straight leads. The primary differences are physical dimensions and packaging format, which do not affect electrical compatibility in applications designed for the MA205C473KAC.

Parameter Comparison

Engineering Selection Recommendations

The SA105C473KAA is a direct electrical equivalent to the MA205C473KAC. Both parts are active products from the same manufacturer with identical electrical performance specifications. Selection between these parts should be based on the following factors:

Physical dimensions differ between the two parts. The MA205C473KAC measures 0.090" diameter by 0.250" length, while the SA105C473KAA measures 0.100" diameter by 0.170" length. PCB layout and component spacing requirements must accommodate the selected part's dimensions.

Regulatory compliance differs. The SA105C473KAA is ROHS3 compliant and REACH unaffected, while the MA205C473KAC is RoHS non-compliant and REACH affected. Applications subject to RoHS3 or REACH regulations must use the SA105C473KAA.

Packaging format differs. The MA205C473KAC is supplied in bulk packaging, while the SA105C473KAA is supplied in cut tape format. Procurement and assembly processes may have preferences or requirements for specific packaging formats.

Inventory availability differs. The SA105C473KAA has significantly higher stock levels (90,268 units) compared to the MA205C473KAC (727 units), which may influence lead time and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can SA105C473KAA be used as a direct replacement for MA205C473KAC in existing designs?

A: Yes, from an electrical standpoint. Both parts have identical capacitance (0.047 µF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). However, physical dimensions differ, so PCB layout must accommodate the SA105C473KAA's 0.100" diameter and 0.170" length specifications.

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

A: The primary differences are physical dimensions, packaging format, and regulatory compliance status. The SA105C473KAA is smaller in length, supplied in cut tape format, and meets ROHS3 and REACH requirements, while the MA205C473KAC is larger in length, supplied in bulk, and does not meet these regulatory standards.

Q: Are there any electrical performance differences between MA205C473KAC and SA105C473KAA?

A: No. Both parts are identical in all electrical specifications: capacitance value, tolerance, voltage rating, temperature coefficient, and operating temperature range.

Q: Which part should be selected for new designs?

A: For new designs without specific regulatory exemptions, the SA105C473KAA is the preferred choice due to ROHS3 compliance and REACH compliance status. For applications requiring the exact physical dimensions of the MA205C473KAC, the original part must be retained.

Q: Does packaging format affect component performance?

A: No. Cut tape (CT) and bulk packaging formats do not affect electrical or mechanical performance. The difference is in procurement and assembly handling only.
