Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: capacitance value (10000 pF), package type (1210/3225 Metric), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and voltage rating (minimum 1000V). Parts are grouped into three categories:

Upgrade Substitutes (KYOCERA AVX): Parts 1210AC103KAT1A and KGM32HR73A103KU maintain identical electrical specifications to the main part but feature improved tolerance (±10% versus ±20%), indicating tighter capacitance control. Both are KYOCERA AVX products with active status and unlimited moisture sensitivity.

Direct Equivalent (KEMET): Part C1210C103MDRAC7800 matches the main part's capacitance, tolerance (±20%), voltage rating (1000V), and temperature coefficient (X7R). Minor dimensional variations exist in length (3.20mm versus 3.30mm) and thickness (1.55mm versus 1.80mm), which remain within the 1210 package specification.

Upgrade Equivalent (KEMET): Part C1210C103KFRAC7800 provides improved tolerance (±10%) and elevated voltage rating (1500V versus 1000V), offering enhanced performance margin while maintaining the same capacitance and package footprint.

Upgrade Equivalent (YAGEO): Part CC1210KKX7RCBB103 delivers improved tolerance (±10%) and maintains the 1000V voltage rating with identical capacitance and temperature coefficient. Packaging format differs (Cut Tape & Digi-Reel versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original 1210AC103MAT1A. Selection between substitutes depends on application-specific requirements:

For designs requiring tighter capacitance tolerance without voltage margin increase, 1210AC103KAT1A or KGM32HR73A103KU (both KYOCERA AVX, ±10% tolerance) are direct functional upgrades. KGM32HR73A103KU is designated as part of the KGM - HV series, indicating high-voltage optimization.

For cross-manufacturer substitution with matching tolerance and voltage specifications, C1210C103MDRAC7800 (KEMET) provides electrical equivalence. This part features low ESL characteristics and is part of the SMD Comm X7R HV series.

For applications requiring enhanced voltage margin, C1210C103KFRAC7800 (KEMET, 1500V rating) offers improved performance headroom while maintaining ±10% tolerance and identical capacitance. Thickness increases to 2.30mm; verify PCB assembly compatibility.

For YAGEO sourcing, CC1210KKX7RCBB103 delivers ±10% tolerance and 1000V rating with reduced thickness (1.45mm), supporting compact assembly requirements. Packaging format is Cut Tape & Digi-Reel rather than Tape & Reel.

Frequently Asked Questions (FAQ)

Q: Can 1210AC103KAT1A replace 1210AC103MAT1A directly? A: Yes. Both parts are KYOCERA AVX 1210 package ceramics with 10000 pF capacitance and 1000V rating. The substitute features ±10% tolerance versus ±20%, representing improved capacitance accuracy. No design changes are required.

Q: What is the difference between C1210C103MDRAC7800 and C1210C103KFRAC7800? A: Both are KEMET 1210 package parts with 10000 pF capacitance. C1210C103MDRAC7800 is rated 1000V with ±20% tolerance. C1210C103KFRAC7800 is rated 1500V with ±10% tolerance and increased thickness (2.30mm). The higher voltage rating provides additional safety margin in high-voltage applications.

Q: Are there package footprint differences between substitutes? A: All parts use the 1210 (3225 Metric) package. Minor dimensional variations exist: KEMET parts measure 3.20mm length versus KYOCERA AVX 3.30mm length. Thickness varies from 1.45mm (YAGEO) to 2.30mm (KEMET 1500V). These variations remain within 1210 package tolerance and do not affect PCB land pattern compatibility.

Q: Which substitute offers the best inventory availability? A: 1210AC103KAT1A (KYOCERA AVX) has the highest inventory at 50,300 pieces, followed by KGM32HR73A103KU at 10,173 pieces. Both are KYOCERA AVX products with ±10% tolerance.

Q: Can CC1210KKX7RCBB103 be used in automated assembly? A: CC1210KKX7RCBB103 is supplied in Cut Tape & Digi-Reel format rather than standard Tape & Reel. Verify that assembly equipment supports this packaging format before substitution.

Q: What is the moisture sensitivity level for all substitutes? A: All listed parts, including the main part 1210AC103MAT1A, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture bake-out requirement prior to soldering.
