Substitute Part Grouping Explanation

Substitute parts for the 1812GC472MAT1A are classified based on tolerance and packaging variations while maintaining identical electrical specifications and mechanical compatibility.

Substitution Criteria:

• Capacitance: 4700 pF (exact match required)
• Voltage Rating: 2000V (2kV) (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Operating Temperature: -55°C to 125°C (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Tolerance Variations: The main part features ±20% tolerance. Upgrade substitutes with ±10% tolerance provide improved accuracy for applications requiring tighter capacitance specifications.

Packaging Variations: Substitute parts are available in Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) formats to accommodate different assembly and procurement workflows.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status with ROHS3 compliance and REACH unaffected certification, ensuring regulatory compliance and long-term availability.

1812GC472KAT1A provides improved tolerance specification (±10% versus ±20%) while maintaining identical electrical and mechanical characteristics. This upgrade is suitable for applications requiring tighter capacitance accuracy. Available in Cut Tape and Digi-Reel® packaging formats for flexible procurement options.

KGM43FR73D472KV represents the KGM - HV series variant with ±10% tolerance and Tape & Reel packaging. Thickness specification is 0.087" (2.21mm), representing a negligible 0.01mm variance from the main part. This part is functionally equivalent for all practical applications.

1812GC472MAT1A (Parametric Equivalent) is an alternative Tape & Reel packaged variant of the main part specification, maintaining identical ±20% tolerance and all electrical parameters.

Selection between these parts depends on packaging requirements, tolerance specifications, and procurement workflow preferences. All parts are electrically and mechanically interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can 1812GC472KAT1A replace 1812GC472MAT1A in my design? A: Yes. Both parts share identical capacitance (4700 pF), voltage rating (2000V), temperature coefficient (X7R), package (1812), and operating temperature range (-55°C to 125°C). The primary difference is tolerance: 1812GC472KAT1A offers ±10% versus ±20% for the main part. This represents an upgrade in accuracy with no compatibility issues.

Q: What is the difference between KGM43FR73D472KV and 1812GC472MAT1A? A: Both parts are electrically identical with 4700 pF capacitance, 2000V rating, and X7R temperature coefficient. KGM43FR73D472KV belongs to the KGM - HV series and features ±10% tolerance. The thickness specification differs by 0.01mm (2.21mm versus 2.20mm), which is within standard manufacturing tolerances and does not affect mechanical compatibility in 1812 (4532 Metric) package footprints.

Q: Are packaging format differences significant for component selection? A: Packaging format (Cut Tape, Digi-Reel®, or Tape & Reel) affects procurement and assembly logistics but does not impact electrical or mechanical performance. Selection depends on your manufacturing process and inventory management requirements.

Q: Do all substitute parts maintain the same compliance certifications? A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All parts are in active production status.

Q: Can I use KGM43FR73D472KV if my design specifies 1812GC472MAT1A? A: Yes. KGM43FR73D472KV is electrically and mechanically compatible. The ±10% tolerance represents an improvement over the ±20% specification. The 0.01mm thickness variance is negligible for standard PCB assembly processes.

Q: What determines whether a part can substitute for 1812GC472MAT1A? A: Substitution requires exact matching of: capacitance value (4700 pF), voltage rating (2000V), temperature coefficient (X7R), package type (1812), operating temperature range (-55°C to 125°C), and mounting type (Surface Mount, MLCC). Tolerance and packaging format variations are acceptable substitution parameters.
