Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825AC102MAT3A\SB are qualified based on the following criteria:

Fixed Parameters (Must Match):

• Capacitance: 1000 pF
• Package / Case: 1825 (4564 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Product Status: Active

Allowable Variations:

• Voltage - Rated: May be equal or higher than 1000V
• Tolerance: May be equal or tighter than ±20%
• Temperature Coefficient: May differ (X7R or C0G/NP0 acceptable for general purpose applications)
• Thickness: May vary within package specifications
• Packaging: May differ (bulk or Tape & Reel)

Two substitute parts meet these criteria and represent voltage and tolerance upgrades from the main part.

Parameter Comparison

Engineering Selection Recommendations

1825GC102KAT1A is the primary substitute for 1825AC102MAT3A\SB. Both parts share identical temperature coefficient (X7R) and maximum thickness specifications. The 1825GC102KAT1A provides a 2 kV rated voltage (double the original specification) with improved tolerance (±10% versus ±20%), maintaining full compatibility with the 1825 package footprint. This part is active in production with the highest inventory availability (2556 units).

1825GA102KAT1A is an alternative substitute offering the same 2 kV voltage upgrade and ±10% tolerance improvement. This part uses C0G/NP0 temperature coefficient instead of X7R, resulting in a thinner profile (0.087" versus 0.100" maximum thickness). The C0G/NP0 coefficient provides superior temperature stability characteristics. This part is active in production with 1145 units in stock.

Both substitute parts are ROHS3 compliant, maintain MSL 1 rating, and operate across the identical -55°C to 125°C temperature range. Selection between the two substitutes depends on whether X7R temperature coefficient characteristics are required (1825GC102KAT1A) or whether C0G/NP0 stability is preferred (1825GA102KAT1A).

Frequently Asked Questions (FAQ)

Q: Can 1825GC102KAT1A or 1825GA102KAT1A be used as direct replacements for 1825AC102MAT3A\SB?

A: Yes. Both substitute parts maintain the same 1000 pF capacitance, 1825 package dimensions, surface mount configuration, and operating temperature range. The substitutes provide higher rated voltage (2 kV versus 1 kV) and tighter tolerance (±10% versus ±20%), making them functionally compatible and electrically superior for the same application space.

Q: What is the difference between 1825GC102KAT1A and 1825GA102KAT1A?

A: The primary differences are temperature coefficient and thickness. 1825GC102KAT1A uses X7R coefficient (matching the original part) with 0.100" maximum thickness. 1825GA102KAT1A uses C0G/NP0 coefficient with 0.087" maximum thickness. Both provide 2 kV voltage rating and ±10% tolerance. Choose 1825GC102KAT1A for X7R characteristics or 1825GA102KAT1A for superior temperature stability and reduced profile height.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts (main and substitutes) are ROHS3 compliant, REACH unaffected, carry MSL 1 rating, and are classified as EAR99 for export control purposes. All are active products in current production.

Q: What packaging options are available?

A: The main part 1825AC102MAT3A\SB is supplied in standard packaging. Both substitute parts 1825GC102KAT1A and 1825GA102KAT1A are available in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Can I use these parts interchangeably in my circuit design?

A: Yes, provided your circuit design accommodates the higher voltage rating (2 kV). The substitutes are backward compatible with applications designed for 1 kV operation. The improved tolerance (±10%) and voltage margin provide additional design margin. Verify that board layout and component spacing accommodate the thickness variations if space is constrained.
