Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility:

Upgrade Substitutes - Parts with higher voltage ratings (2kV, 2.5kV, 3kV) that maintain identical capacitance (1000 pF), tolerance (±10%), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and 1808 package footprint. These parts are pin-compatible and functionally interchangeable in applications where higher voltage margin is acceptable. Thickness may increase with higher voltage ratings.

Parametric Equivalent - Parts with identical electrical specifications (1000 pF, ±10%, 1500V, X7R) and same 1808 package, differing only in packaging format (Cut Tape vs. Tape & Reel).

Substitution eligibility is determined by:

• Matching capacitance value (1000 pF)
• Matching tolerance (±10%)
• Equal or higher voltage rating (≥1500V)
• Matching temperature coefficient (X7R)
• Matching operating temperature range (-55°C to 125°C)
• Compatible 1808 package footprint
• Surface mount MLCC mounting type

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original 1808SC102KATRE specification. Selection among substitutes should be based on voltage margin requirements and physical clearance constraints.

For applications requiring the original 1500V rating with minimal thickness, the parametric equivalent 1808SC102KAT1A provides identical electrical performance with higher inventory availability (5443 units).

For applications tolerating higher voltage ratings, KYOCERA AVX upgrade options (1808GC102KAT1A at 2kV, 1808WC102KAT1A at 2.5kV, 1808HC102KAT1A at 3kV) and KGM series high-voltage variants (KGM42CR73D102KY at 2kV, KGM42CR73U102KY at 3kV) provide increased voltage margin while maintaining identical footprint and capacitance.

Cross-manufacturer alternatives from KEMET (C1808C102KGRAC7800), TDK Corporation (C4520X7R3D102K130KA), and Johanson Dielectrics (VPDP202W102K1GV001E, VPDP302W102K1GV001E) are available with 2kV or 3kV ratings. Physical thickness variations range from 0.059" to 0.087", requiring PCB layout verification for height-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 2kV or 3kV rated capacitor in place of the 1500V 1808SC102KATRE?

A: Yes. Higher voltage-rated capacitors are electrically compatible substitutes. The 1000 pF capacitance, ±10% tolerance, X7R temperature coefficient, and operating temperature range remain identical. Higher voltage ratings provide additional safety margin in the circuit. Physical thickness may increase with higher voltage ratings, requiring verification of PCB clearance.

Q: What is the difference between 1808SC102KATRE and 1808SC102KAT1A?

A: Both parts are parametric equivalents with identical electrical specifications (1000 pF, ±10%, 1500V, X7R, -55°C to 125°C) and 1808 package. The primary difference is packaging format: 1808SC102KATRE is supplied in Cut Tape format, while 1808SC102KAT1A is supplied in Tape & Reel format. Inventory availability differs (1087 vs. 5443 units).

Q: Are KYOCERA AVX, KEMET, TDK, and Johanson Dielectrics parts interchangeable?

A: Yes, for the specified electrical parameters. All listed parts share 1000 pF capacitance, ±10% tolerance, X7R temperature coefficient, 1808 package footprint, and surface mount MLCC mounting type. Physical dimensions vary slightly (length 0.177" to 0.185", thickness 0.059" to 0.087"), requiring PCB layout verification. All parts are ROHS3 compliant.

Q: What does the 1808 package designation mean?

A: 1808 is the imperial designation for a surface mount ceramic capacitor package measuring 0.181" length × 0.079" width (approximately 4.60mm × 2.00mm). The metric equivalent is 4520. All listed parts use this identical footprint and are mechanically interchangeable on the PCB.

Q: Does higher voltage rating affect capacitance stability?

A: No. All listed parts maintain X7R temperature coefficient and identical operating temperature range (-55°C to 125°C), ensuring stable capacitance across temperature variations regardless of voltage rating selection.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed parts carry MSL 1 rating, eliminating moisture-related handling constraints.
