SR387C104KAR Equivalent & Substitute Parts

Part Overview

The SR387C104KAR is a 0.1 µF ceramic capacitor rated for 500V with X7R temperature coefficient, manufactured by KYOCERA AVX in the SkyCap® SR series. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating range. The part is active and in stock with ROHS3 compliance. Equivalent and substitute parts are identified based on matching electrical specifications and compatible mechanical parameters for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters:

• Capacitance value: 0.1 µF
• Tolerance: ±10%
• Voltage rating: 500V
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 125°C
• Mounting type: Through Hole
• Package type: Radial

All identified substitute parts meet these core electrical specifications. Physical dimensions and lead configurations vary within acceptable ranges for through-hole radial mounting. Lead spacing and body dimensions are secondary considerations that depend on specific PCB layout requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the SR387C104KAR. Selection between substitutes depends on PCB layout constraints:

KYOCERA AVX SkyCap® SR Series (SR307C104KAA, SR307C104KAR): Direct manufacturer alternatives with reduced lead spacing (0.200" vs 0.375") and lower profile heights. Suitable for compact layouts. Differ only in lead style (straight vs formed).

KEMET GoldMax 300 Comm X7R HV Series (C330C104KCR5TA, C350C104KCR5TA): Cross-manufacturer alternatives with identical electrical specifications. C330C104KCR5TA maintains similar footprint to SR307 variants. C350C104KCR5TA features larger body dimensions (0.500" length, 0.400" lead spacing) and is suitable for applications where physical size is not constrained.

All parts share identical capacitance, voltage rating, tolerance, temperature coefficient, and operating temperature range. Physical dimensions are the primary differentiator for PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can SR307C104KAA and SR307C104KAR be used interchangeably with SR387C104KAR?

A: Both parts are electrically equivalent with identical capacitance, voltage, tolerance, and temperature specifications. The primary difference is lead spacing (0.200" vs 0.375") and body dimensions. Substitution requires PCB layout verification to confirm hole spacing compatibility.

Q: What is the difference between KYOCERA AVX and KEMET substitute options?

A: Both manufacturers provide parts meeting identical electrical specifications. KYOCERA AVX substitutes (SR307 series) maintain the same manufacturer lineage as the original part. KEMET substitutes (C330C and C350C series) are cross-manufacturer alternatives with different physical packages. Selection depends on PCB design requirements and supplier availability.

Q: Is C350C104KCR5TA suitable as a direct replacement for SR387C104KAR?

A: C350C104KCR5TA meets all electrical requirements but features significantly larger dimensions (0.500" length, 0.560" height, 0.400" lead spacing). It is electrically compatible but requires PCB layout verification due to increased physical footprint.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the SR387C104KAR.

Q: What determines whether a part can substitute for the SR387C104KAR?

A: Substitution is based on matching capacitance (0.1 µF), tolerance (±10%), voltage rating (500V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), mounting type (through hole), and package type (radial). Physical dimensions are secondary and depend on specific PCB layout constraints.
