1808GA470MAT1A Equivalent & Substitute Parts

Part Overview

The 1808GA470MAT1A is a 47 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 2000V (2kV) operation with C0G/NP0 temperature coefficient stability. This surface-mount multilayer ceramic capacitor (MLCC) in 1808 (4520 Metric) package form factor is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating temperature range. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance can be maintained within the specified mechanical and environmental constraints, or when upgraded voltage ratings provide enhanced design margin without compromising form factor compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808GA470MAT1A is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance value: 47 pF (exact match required)
• Temperature coefficient: C0G/NP0 (mandatory for stability equivalence)
• Package / Case: 1808 (4520 Metric) form factor (mechanical compatibility)
• Mounting type: Surface Mount, MLCC (assembly process compatibility)
• Operating temperature range: -55°C to 125°C minimum (functional equivalence)
• RoHS3 compliance and MSL 1 rating (regulatory and environmental equivalence)

Voltage Rating Consideration: Substitute parts with equal or higher voltage ratings (≥2000V) are acceptable. Higher voltage ratings provide increased design margin and do not compromise circuit functionality when the original 2000V specification is met or exceeded.

Tolerance Variation: Tolerance specifications may vary (±20%, ±10%, ±5%) among substitute parts. Tighter tolerances represent functional improvements and do not prevent substitution.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts meet the core substitution criteria for the 1808GA470MAT1A:

1808HA470JAT1A (KYOCERA AVX): This part provides a direct upgrade path with identical mechanical dimensions (0.181" L x 0.079" W, 0.057" max thickness) and identical package form factor. The voltage rating increases from 2000V to 3000V, and tolerance tightens from ±20% to ±5%. All compliance certifications (RoHS3, MSL 1, REACH Unaffected, EAR99) remain equivalent. This part is suitable for applications requiring improved voltage margin or tighter capacitance tolerance without any form factor constraints.

C4520C0G3F470K160KA (TDK Corporation): This part maintains the 47 pF capacitance, C0G/NP0 temperature coefficient, and 3000V voltage rating. Mechanical dimensions show minor variation: length reduces from 0.181" to 0.177" (4.60mm to 4.50mm), while thickness increases from 0.057" to 0.071" (1.45mm to 1.80mm). Tolerance is ±10%. All compliance certifications remain equivalent. This part is suitable for applications where the dimensional variation does not conflict with PCB layout constraints.

Both substitute parts maintain Active product status and full regulatory compliance. Selection between substitutes depends on specific PCB layout requirements and tolerance specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 1808HA470JAT1A directly replace the 1808GA470MAT1A without PCB layout modifications?

A: Yes. The 1808HA470JAT1A maintains identical external dimensions (0.181" L x 0.079" W) and maximum thickness (0.057"), ensuring direct mechanical compatibility with existing PCB footprints designed for the 1808GA470MAT1A.

Q: What is the primary advantage of the 1808HA470JAT1A over the main part?

A: The 1808HA470JAT1A provides a 50% increase in voltage rating (3000V vs. 2000V) and tighter capacitance tolerance (±5% vs. ±20%), both from the same manufacturer, with identical form factor and compliance certifications.

Q: Can the C4520C0G3F470K160KA be used as a direct replacement?

A: The C4520C0G3F470K160KA is electrically equivalent but has different mechanical dimensions. Length is slightly shorter (0.177" vs. 0.181"), while thickness is greater (0.071" vs. 0.057"). PCB layout verification is required to confirm compatibility with existing footprints and clearance constraints.

Q: Are all three parts RoHS3 compliant?

A: Yes. The main part 1808GA470MAT1A and both substitute parts (1808HA470JAT1A and C4520C0G3F470K160KA) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What tolerance specifications apply to each part?

A: The 1808GA470MAT1A has ±20% tolerance, the 1808HA470JAT1A has ±5% tolerance, and the C4520C0G3F470K160KA has ±10% tolerance. All three maintain the same 47 pF nominal capacitance value.

Q: Do all parts operate across the same temperature range?

A: Yes. All three parts operate across the -55°C to 125°C temperature range with C0G/NP0 temperature coefficient stability.
