Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 1812HC102MAT3A\SB is based on the following critical parameters: capacitance value (1000 pF), voltage rating (3000V), temperature coefficient (X7R), package type (1812/4532 Metric), and mounting configuration (Surface Mount MLCC). All identified substitutes maintain these core electrical specifications and physical package compatibility.

Substitutes are categorized as follows:

Direct Equivalents (Same Tolerance ±20%): Parts with identical electrical performance and tolerance specifications, differing only in packaging format or manufacturer series designation.

Upgrade Substitutes (Tighter Tolerance ±10%): Parts with improved capacitance tolerance, providing enhanced precision while maintaining all other electrical and mechanical parameters. These are suitable for applications requiring tighter capacitance control.

Cross-Manufacturer Alternatives: Parts from alternative manufacturers (KEMET) meeting identical electrical specifications and package requirements, with potential minor dimensional variations within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with current environmental standards. Selection between substitutes should be based on the following criteria:

For Direct Equivalency: KGM43FR73U102MV and 1812HC102MAT1A provide identical electrical performance and tolerance specifications to the primary part. KGM43FR73U102MV is available in Tape & Reel packaging, while 1812HC102MAT1A is supplied in Cut Tape & Digi-Reel format. Both are suitable for applications where ±20% tolerance is acceptable.

For Improved Tolerance: 1812HC102KAT1A and KGM43FR73U102KV offer ±10% tolerance, providing tighter capacitance control. KGM43FR73U102KV is designated as part of the KGM - HV series and offers the highest inventory availability (3091 Pcs). Both maintain identical voltage rating and temperature coefficient specifications.

For Cross-Manufacturer Compatibility: C1812C102KHRAC7800 (KEMET) provides ±10% tolerance with documented Low ESL characteristics. Physical thickness is reduced to 0.071" (1.80mm) compared to 0.087" (2.20mm) for KYOCERA AVX parts, which may be advantageous for space-constrained applications. All compliance certifications remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1812HC102MAT3A\SB with KGM43FR73U102MV? A: Yes. Both parts share identical electrical specifications (1000 pF, ±20%, 3000V, X7R) and 1812 package configuration. The primary difference is packaging format: KGM43FR73U102MV is supplied in Tape & Reel, while the original part uses standard packaging. Electrical performance and board-level compatibility are equivalent.

Q: What is the advantage of using 1812HC102KAT1A or KGM43FR73U102KV? A: These parts feature ±10% capacitance tolerance compared to ±20% for the original part. Tighter tolerance provides improved circuit performance in applications sensitive to capacitance variation. All other electrical and mechanical parameters remain identical.

Q: Is the KEMET C1812C102KHRAC7800 a suitable replacement? A: Yes, for applications where cross-manufacturer sourcing is acceptable. The KEMET part maintains identical electrical specifications and 1812 package compatibility. Physical thickness is reduced to 1.80mm (versus 2.20mm for KYOCERA AVX), which may provide design advantages in height-constrained layouts. Low ESL characteristics are documented.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel, Cut Tape, and Digi-Reel packaging formats do not affect component electrical characteristics. Selection should be based on assembly process requirements and inventory management preferences.

Q: Are all substitutes ROHS3 compliant? A: Yes. All identified substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards.

Q: Can I use these substitutes interchangeably on the same PCB? A: Yes, provided the application tolerates the specified tolerance range. Parts with ±20% tolerance (1812HC102MAT3A\SB, KGM43FR73U102MV, 1812HC102MAT1A) are directly interchangeable. Parts with ±10% tolerance (1812HC102KAT1A, KGM43FR73U102KV, C1812C102KHRAC7800) offer improved precision and are suitable for any application accepting the original part.
