Key Parameters

Substitute Part Grouping Explanation

Substitute parts are organized into two categories based on electrical parameter compatibility:

Upgrade Category (Higher Voltage Rating): Parts with 100V voltage rating provide enhanced voltage margin while maintaining identical capacitance, tolerance, temperature coefficient, and package dimensions. These are direct functional upgrades suitable for applications where higher voltage headroom is beneficial.

Direct Category (Same Voltage Rating): Parts with matching 50V voltage rating and X7R temperature coefficient from alternative manufacturers (KEMET, YAGEO, Vishay Vitramon) provide equivalent electrical performance with identical mechanical compatibility.

Alternative Category (Different Temperature Coefficient): The C0805C183J5GAC7800 offers C0G/NP0 temperature coefficient with ±5% tolerance at 50V, providing superior temperature stability for applications requiring tighter capacitance tolerance.

Substitution eligibility is determined by:

• Matching capacitance value (0.018µF)
• Voltage rating equal to or greater than 50V
• Compatible temperature coefficient (X7R or C0G/NP0)
• Identical 0805 package footprint
• Surface mount MLCC mounting type
• Moisture Sensitivity Level 1

Engineering Selection Recommendations

For RoHS3 Compliance Requirement: Select from KYOCERA AVX KGM series (KGM21AR72A183JU, KGM21AR72A183KU, KGM21NR71H183JT, KGM21NR71H183KT), KEMET C0805C series (C0805C183K5RAC7800, C0805C183J5GAC7800, C0805C183J5RAC7800, C0805C183K1RAC7800), YAGEO CC0805KRX7R9BB183, or Vishay Vitramon VJ0805Y183KXACW1BC. All listed substitutes are ROHS3 Compliant, whereas the original part is RoHS non-compliant.

For Voltage Margin Enhancement: KGM21AR72A183KU (100V, ±10%, highest inventory at 28575 Pcs) or C0805C183K1RAC7800 (100V, ±10%, KEMET alternative) provide doubled voltage rating while maintaining tolerance and temperature coefficient specifications.

For Tolerance Tightening: C0805C183J5RAC7800 (±5%, 50V, X7R) or KGM21NR71H183JT (±5%, 50V, X7R) reduce capacitance tolerance from ±10% to ±5% for applications requiring tighter specifications.

For Temperature Stability: C0805C183J5GAC7800 (C0G/NP0 temperature coefficient, ±5%, 50V) provides superior temperature stability compared to X7R coefficient, suitable for precision analog circuits.

For Same-Manufacturer Continuity: KGM21NR71H183KT (KYOCERA AVX, 50V, ±10%, X7R) maintains manufacturer consistency with identical electrical specifications and improved RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can I use a 100V rated capacitor in place of the 50V original part? A: Yes. Higher voltage rating provides additional safety margin and is electrically compatible. The 100V substitutes (KGM21AR72A183KU, KGM21AR72A183JU, C0805C183K1RAC7800) maintain identical capacitance and temperature coefficient while offering enhanced voltage headroom.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R provides ±15% capacitance variation across the -55°C to 125°C operating range. C0G/NP0 provides superior stability with ±0.3% variation per °C, suitable for precision applications. The C0805C183J5GAC7800 offers C0G/NP0 performance if temperature stability is critical.

Q: Are all substitute parts mechanically compatible with the 0805 footprint? A: Yes. All listed substitutes use the 0805 (2012 Metric) package with identical 0.079" L x 0.049" W footprint dimensions. Thickness varies between 0.024" and 0.057" maximum; verify PCB clearance for components exceeding 0.037" thickness.

Q: Why is the original part RoHS non-compliant while substitutes are ROHS3 compliant? A: Manufacturing standards have evolved. All substitute parts meet current ROHS3 compliance requirements. If RoHS compliance is mandatory for your application, select from the listed substitutes.

Q: Which substitute offers the best inventory availability? A: KGM21AR72A183KU (KYOCERA AVX, 100V, ±10%) has the highest inventory at 28575 Pcs, followed by C0805C183K5RAC7800 (KEMET, 50V, ±10%) at 23153 Pcs.

Q: Can I mix different manufacturers in the same design? A: Yes. All substitutes meet identical electrical specifications (0.018µF, X7R, 50V or higher) and mechanical requirements (0805 package). Cross-manufacturer substitution is electrically valid.

Q: What is Moisture Sensitivity Level 1? A: MSL 1 indicates unlimited shelf life without moisture control requirements. All listed parts carry MSL 1 rating, requiring no special storage or handling precautions.
