SR201C473MAATR2 Equivalent & Substitute Parts

Part Overview

The SR201C473MAATR2 is a 0.047 µF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KYOCERA AVX under the SkyCap® SR series. This through-hole radial component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and currently in active production status with 1046 units in stock.

Substitute parts become necessary when the primary manufacturer's stock is unavailable, when alternative packaging formats are required for assembly processes, or when tolerance specifications can be tightened to meet circuit performance requirements without compromising functionality.

Key Parameters

Package Type	Radial
RoHS Status	ROHS3 Compliant
Lead Style	Straight

Substitute Part Grouping Explanation

Substitution eligibility for the SR201C473MAATR2 is determined by the following critical parameters:

Capacitance Value: Must be 0.047 µF (no deviation permitted)
Voltage Rating: Must be 100V or higher
Temperature Coefficient: Must be X7R
Operating Temperature Range: Must support -55°C to 125°C
Mounting Type: Must be Through Hole
Package Type: Must be Radial
Compliance: Must maintain ROHS3 and REACH compliance status

The substitute parts listed below meet all these criteria. Tolerance specifications may vary (±20% vs. ±10%), and physical dimensions may differ slightly while maintaining functional compatibility. Lead spacing and lead style variations are acceptable provided the component fits within the PCB layout constraints.

Engineering Selection Recommendations

Both Murata substitute parts (RDER72A473K1P1H03B and RDER72A473K1S1H03A) are functionally equivalent to the SR201C473MAATR2 for general-purpose applications. Selection between these options depends on assembly and procurement requirements:

RDER72A473K1P1H03B is supplied in Bulk packaging and offers 1970 units in stock, providing higher availability for large-volume production runs.

RDER72A473K1S1H03A is supplied in Cut Tape (CT) packaging and offers 1700 units in stock, suitable for automated pick-and-place assembly processes.

Both substitute parts feature tighter tolerance specifications (±10% versus ±20%), which may improve circuit performance in applications where capacitance accuracy is critical. The slightly smaller physical dimensions and formed lead style of the Murata components require verification against PCB layout constraints, particularly regarding lead spacing (0.098" vs. 0.100") and component height (0.197" vs. 0.200").

All three parts maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification) and support the full operating temperature range required for the application.

Frequently Asked Questions (FAQ)

Q: Can RDER72A473K1P1H03B and RDER72A473K1S1H03A be used interchangeably with SR201C473MAATR2?

A: Yes, both Murata parts are electrically and mechanically compatible substitutes. The primary differences are packaging format (Bulk vs. Cut Tape) and lead configuration (Formed Leads vs. Straight). PCB layout must accommodate the slightly different physical dimensions and lead spacing.

Q: What is the significance of the tolerance difference (±20% vs. ±10%)?

A: The substitute parts feature tighter tolerance specifications, meaning their actual capacitance values will be closer to the nominal 0.047 µF specification. This provides improved circuit performance in applications sensitive to capacitance variation. The original part's ±20% tolerance is still within acceptable limits for general-purpose applications.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts maintain identical compliance status: ROHS3 compliant, REACH unaffected, and EAR99 ECCN classification. They are suitable for the same regulatory environments and applications.

Q: How do the physical dimensions affect PCB design?

A: The Murata substitutes are slightly smaller (4.50mm x 3.15mm vs. 5.08mm x 3.18mm) with marginally closer lead spacing (2.50mm vs. 2.54mm). Verify that existing PCB footprints accommodate these dimensional variations. The formed lead style of Murata parts may require different insertion force profiles during assembly.

Q: Which substitute should I select for high-volume production?

A: RDER72A473K1P1H03B (Bulk packaging) is recommended for high-volume manual or semi-automated assembly. RDER72A473K1S1H03A (Cut Tape packaging) is optimized for fully automated pick-and-place assembly lines.
