SV14AC103MAR Equivalent & Substitute Parts

Part Overview

The SV14AC103MAR is a 10000 pF ceramic capacitor rated for 1000V (1kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in the SV series. This through-hole radial component is designed for general-purpose high-voltage applications and is currently in active production status. Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative tolerance specifications are required, or when different packaging formats better suit assembly requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SV14AC103MAR is determined by the following critical parameters:

• Capacitance value: 10000 pF (exact match required)
• Voltage rating: 1000V (1kV) minimum (equal or higher acceptable)
• Temperature coefficient: X7R (required for temperature stability)
• Mounting type: Through Hole (required for PCB compatibility)
• Package type: Radial (required for lead configuration)
• Lead spacing: 0.200" (5.08mm) (required for footprint compatibility)

All substitute parts listed maintain these core electrical and mechanical parameters. Variations in tolerance, physical dimensions, and product status are noted but do not prevent functional substitution when the above criteria are met.

Parameter Comparison

Engineering Selection Recommendations

For new designs, C322C103JDR5TA and C322C103KDR5TA from KEMET are preferred substitutes. Both parts maintain active product status and offer improved tolerance specifications (±5% and ±10% respectively) compared to the original SV14AC103MAR (±20%). These KEMET parts are fully ROHS3 compliant and suitable for long-term production use.

The Murata Electronics parts RDER73A103K3K1H03B and RDER73A103K3M1H03A are functionally compatible but carry "Not For New Designs" status. These parts are suitable only for legacy system maintenance or replacement applications where existing inventory must be maintained. The lead spacing on Murata parts is 0.197" (5.00mm), which differs slightly from the 0.200" (5.08mm) standard but remains within acceptable PCB footprint tolerances for radial through-hole components.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can C322C103JDR5TA replace SV14AC103MAR directly on the PCB?

A: Yes. Both parts share identical capacitance (10000 pF), voltage rating (1000V), temperature coefficient (X7R), mounting type (through hole), package type (radial), and lead spacing (0.200" / 5.08mm). The improved tolerance (±5% vs ±20%) makes this an upgrade substitute.

Q: What is the difference between C322C103JDR5TA and C322C103KDR5TA?

A: Both are KEMET GoldMax 300 Comm X7R HV series parts with identical electrical specifications except tolerance. C322C103JDR5TA offers ±5% tolerance, while C322C103KDR5TA offers ±10% tolerance. Selection depends on circuit tolerance requirements.

Q: Why are Murata parts marked "Not For New Designs"?

A: This designation indicates that Murata has discontinued these parts for new production. While they remain functionally compatible and suitable for replacement or legacy applications, they should not be selected for new circuit designs due to potential future availability constraints.

Q: Does the 0.197" lead spacing on Murata parts affect PCB compatibility?

A: The 0.197" (5.00mm) lead spacing on Murata parts differs slightly from the standard 0.200" (5.08mm). This minor difference remains within acceptable mechanical tolerances for radial through-hole PCB footprints and does not prevent physical installation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—C322C103JDR5TA, C322C103KDR5TA, RDER73A103K3K1H03B, and RDER73A103K3M1H03A—are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Which substitute offers the best tolerance specification?

A: C322C103JDR5TA provides the tightest tolerance at ±5%, compared to ±10% for C322C103KDR5TA and the Murata parts, and ±20% for the original SV14AC103MAR. Selection should be based on circuit tolerance requirements.
