Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812GC471MAT1A is determined by the following criteria:

Primary Electrical Parameters:

• Capacitance value must equal 470 pF
• Voltage rating must be equal to or greater than 2000V
• Temperature coefficient must be X7R or C0G/NP0 (both provide stable performance across the operating temperature range)
• Operating temperature range must encompass -55°C to 125°C

Mechanical Parameters:

• Package format must be 1812 (4532 Metric)
• Mounting type must be Surface Mount, MLCC
• Physical dimensions must be compatible with 1812 footprint specifications

Compliance Parameters:

• RoHS3 compliance required
• Moisture Sensitivity Level 1 (Unlimited) required
• Active product status required

Tolerance variations (±5%, ±10%, ±20%) are acceptable as they represent different grades of the same capacitance value. Voltage ratings above 2000V provide enhanced margin and are acceptable substitutes. Temperature coefficient variants (X7R and C0G/NP0) both meet the stability requirements for the -55°C to 125°C operating range.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full compatibility with the 1812GC471MAT1A in terms of electrical performance, mechanical fit, and regulatory compliance. Selection among these alternatives should be based on the following factors:

1812GC471KAT1A provides direct electrical equivalence with improved tolerance (±10% versus ±20%) while maintaining identical voltage rating, temperature coefficient, and physical dimensions. This part represents the closest functional match with tighter capacitance specification.

1812GA471JAT1A offers the tightest tolerance specification (±5%) with C0G/NP0 temperature coefficient, which provides superior temperature stability compared to X7R. However, this part features increased thickness (0.087" versus 0.071"), which may impact PCB layout in space-constrained applications. Packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel).

1812HC471KAT1A and KGM43ER73U471KV both provide elevated voltage rating (3000V versus 2000V), offering enhanced safety margin for high-voltage applications. Both maintain X7R temperature coefficient and identical physical dimensions to the main part. The KGM43ER73U471KV is designated as part of the KGM - HV series, indicating specialized high-voltage design. HTSUS classification differs slightly (8532.23.0020 versus 8532.24.0020).

All substitute parts are active products with ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can 1812GC471KAT1A directly replace 1812GC471MAT1A?

A: Yes. Both parts share identical capacitance (470 pF), voltage rating (2000V), temperature coefficient (X7R), package format (1812), and physical dimensions. The primary difference is tolerance specification (±10% versus ±20%), which represents improved precision without affecting functional compatibility.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: Both temperature coefficients provide stable capacitance across the -55°C to 125°C operating range required for this application. X7R exhibits capacitance variation of ±15% across the temperature range. C0G/NP0 provides superior stability with minimal variation. Selection depends on application-specific tolerance requirements.

Q: Why do 1812HC471KAT1A and KGM43ER73U471KV have 3000V ratings instead of 2000V?

A: These parts provide elevated voltage rating, offering increased safety margin for high-voltage circuit designs. They are electrically and mechanically compatible with the 1812GC471MAT1A and can be used in applications where the original 2000V specification is adequate, providing additional design headroom.

Q: Does the increased thickness of 1812GA471JAT1A affect PCB compatibility?

A: The 1812GA471JAT1A has maximum thickness of 0.087" (2.20mm) compared to 0.071" (1.80mm) for other listed parts. This difference may impact PCB layout in applications with strict height constraints or where multiple components are densely populated. Verify PCB design clearances before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with standard manufacturing processes and storage requirements.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging is standard continuous reel format suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel® packaging provides flexibility for lower-volume applications or mixed component sourcing. Both formats are compatible with standard surface mount assembly equipment.
