Equivalent & Substitute Parts for SA105C103MARC

Part Overview

The SA105C103MARC is a 10000 pF ceramic capacitor manufactured by KYOCERA AVX in the SpinGuard® SA series. This axial through-hole component operates at 50V with X7R temperature coefficient and ±20% tolerance. The part is active and ROHS3 compliant, suitable for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating range.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter constraints of the application circuit. Substitution eligibility is determined by matching capacitance value, temperature coefficient, voltage rating compatibility, and physical form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SA105C103MARC is determined by the following criteria:

Primary Matching Parameters:

• Capacitance value: 10000 pF (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)

Secondary Compatibility Parameters:

• Voltage Rating: Equal to or greater than 50V
• Tolerance: ±20% or tighter (±10%, ±5%)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Physical Dimensions: Equivalent or compatible with PCB layout constraints
• RoHS Status: ROHS3 Compliant (maintained across all substitutes)

Substitute parts are grouped into two categories based on voltage rating: parts rated at 50V (direct substitutes) and parts rated at 100V (upgraded substitutes with higher voltage margin).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (50V Rating, Same Voltage Class):

SA105C103KAR and C410C103K5R5TA7200 are direct substitutes for the SA105C103MARC. Both maintain the 50V voltage rating and X7R temperature coefficient. SA105C103KAR offers tighter ±10% tolerance within the same KYOCERA AVX SpinGuard® SA series and identical physical dimensions. C410C103K5R5TA7200 provides equivalent performance from KEMET's AxiMax 400 Comm X7R series with higher inventory availability (15569 pcs).

A103K15X7RF5UAA from Vishay Beyschlag/Draloric/BC Components is a direct electrical substitute at 50V with ±10% tolerance. Physical dimensions are slightly smaller (0.098" Dia x 0.150" L versus 0.100" Dia x 0.170" L), requiring verification of PCB layout compatibility. This part offers the highest inventory level (21444 pcs).

Upgraded Substitutes (100V Rating, Higher Voltage Margin):

SA101C103JARC and C410C103K1R5TA7200 are upgraded substitutes with 100V voltage rating, providing additional voltage margin beyond the 50V requirement. SA101C103JARC maintains KYOCERA AVX manufacturing with improved ±5% tolerance. C410C103K1R5TA7200 is the KEMET equivalent with ±10% tolerance. Both parts maintain identical physical dimensions and X7R temperature coefficient. These upgrades are suitable for applications requiring enhanced voltage safety margin or where higher-rated components are preferred for circuit reliability.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can SA105C103KAR replace SA105C103MARC directly?

A: Yes. SA105C103KAR is a direct substitute with identical capacitance (10000 pF), voltage rating (50V), temperature coefficient (X7R), and physical dimensions (0.100" Dia x 0.170" L). The tighter ±10% tolerance is compatible with applications designed for the ±20% tolerance of the original part.

Q: What is the difference between 50V and 100V rated substitutes?

A: The 50V substitutes (SA105C103KAR, C410C103K5R5TA7200, A103K15X7RF5UAA) match the original part's voltage rating. The 100V substitutes (SA101C103JARC, C410C103K1R5TA7200) provide higher voltage margin and are suitable for applications where additional voltage safety factor is required or preferred.

Q: Does the Vishay part A103K15X7RF5UAA have different physical dimensions?

A: Yes. A103K15X7RF5UAA measures 0.098" Dia x 0.150" L (2.50mm x 3.80mm), compared to the original 0.100" Dia x 0.170" L (2.54mm x 4.32mm). PCB layout compatibility must be verified before substitution, as the smaller form factor may affect lead spacing and mounting hole alignment.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification consistent with SA105C103MARC.

Q: Which substitute has the best inventory availability?

A: A103K15X7RF5UAA from Vishay Beyschlag/Draloric/BC Components has the highest inventory level at 21444 pcs. C410C103K5R5TA7200 from KEMET is the second highest at 15569 pcs.

Q: Can I use a 100V rated part in a circuit designed for 50V?

A: Yes. A 100V rated capacitor can be used in a 50V circuit. The higher voltage rating provides additional safety margin and does not affect electrical performance at the lower operating voltage.

Q: What tolerance should I select for my application?

A: Tolerance selection depends on circuit requirements. The original ±20% tolerance is suitable for general-purpose applications. Tighter tolerances (±10%, ±5%) are available in substitute parts for applications requiring more precise capacitance values.
