Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 1812SC472KATBE is based on the following allowed parameters:

Electrical Compatibility: Capacitance value (4700 pF) and tolerance (±10%) must remain constant. Temperature coefficient (X7R) must match. Operating temperature range (-55°C ~ 125°C) must be maintained or exceeded.

Mechanical Compatibility: Package / Case designation (1812 / 4532 Metric) and mounting type (Surface Mount, MLCC) must be identical. Physical dimensions must be compatible with PCB layout constraints.

Voltage Rating Flexibility: Substitute parts may have equal or higher voltage ratings. A higher voltage rating (2000V / 2kV) provides design margin and is acceptable for direct substitution in applications originally specified for 1500V (1.5kV).

Compliance & Certification: RoHS3 compliance and MSL Level 1 status must be maintained. REACH and ECCN classifications must align with original specifications.

Manufacturer Substitution: Parts from alternative manufacturers (KEMET) are acceptable when all electrical and mechanical parameters match or exceed the original specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Same Voltage Rating): The C1812C472KFRAC7800 from KEMET is a direct equivalent to the 1812SC472KATBE. Both components share identical electrical specifications (4700 pF, ±10%, 1500V, X7R) and mechanical compatibility (1812 package, surface mount). Both are Active status products with ROHS3 compliance and MSL Level 1 rating. This substitute is suitable for one-to-one replacement in existing designs.

Upgraded Substitution (Higher Voltage Rating): The 1812GC472KAT1A and KGM43FR73D472KV are voltage-upgraded alternatives from KYOCERA AVX, both rated at 2000V (2kV) instead of 1500V (1.5kV). These parts maintain identical capacitance, tolerance, temperature coefficient, and package specifications. The higher voltage rating provides additional design margin and is compatible with applications originally specified for 1500V operation. Both are Active status products with ROHS3 compliance and MSL Level 1 rating.

Packaging Format Consideration: The 1812GC472KAT1A is available in Cut Tape (CT) & Digi-Reel® packaging, while the KGM43FR73D472KV is supplied in Tape & Reel (TR) format. The C1812C472KFRAC7800 is also available in Tape & Reel (TR). Selection between these formats depends on procurement and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1812GC472KAT1A or KGM43FR73D472KV be used as direct replacements for the 1812SC472KATBE?

A: Yes. Both parts are direct substitutes with identical capacitance (4700 pF), tolerance (±10%), temperature coefficient (X7R), and package (1812 / 4532 Metric). The higher voltage rating (2000V vs. 1500V) is compatible with applications originally specified for 1500V operation and provides additional design margin.

Q: What is the difference between the 1812GC472KAT1A and KGM43FR73D472KV?

A: Both parts are electrically and mechanically identical with 4700 pF capacitance at 2000V rating in 1812 package. The primary difference is packaging format: 1812GC472KAT1A is supplied in Cut Tape (CT) & Digi-Reel® format, while KGM43FR73D472KV is supplied in Tape & Reel (TR) format. Selection depends on assembly line compatibility and procurement preferences.

Q: Is the KEMET C1812C472KFRAC7800 compatible with the original 1812SC472KATBE specification?

A: Yes. The C1812C472KFRAC7800 is a manufacturer-recommended equivalent with matching electrical specifications (4700 pF, ±10%, 1500V, X7R) and identical package (1812 / 4532 Metric). Both components are ROHS3 compliant with MSL Level 1 rating and Active product status. Physical dimensions are compatible with standard 1812 PCB footprints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (1812GC472KAT1A, KGM43FR73D472KV, and C1812C472KFRAC7800) are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original 1812SC472KATBE specification.

Q: Can I use a 2000V rated capacitor in a circuit designed for 1500V?

A: Yes. A higher voltage rating provides additional design margin and is suitable for direct substitution in applications originally specified for lower voltage ratings. The electrical performance and physical compatibility remain unchanged.
