Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 12103C274JAT2A is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 0.27 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 1210 (3225 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical Dimensions: 0.126" L x 0.098" W, 0.037" max thickness (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 25V (uprating permitted)
• Manufacturer: Alternative manufacturers acceptable if all other parameters match

The identified substitute part 12105C274JAT2A maintains all mandatory parameters while providing a voltage rating upgrade from 25V to 50V, enabling use in higher voltage applications without changing footprint or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the 12103C274JAT2A and 12105C274JAT2A are Active product status components manufactured by KYOCERA AVX with identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and MSL 1 (Unlimited). The 12103C274JAT2A operates at 25V rated voltage, while the 12105C274JAT2A provides a 50V rated voltage within the same physical footprint and electrical specifications. Selection between these parts depends on circuit voltage requirements: use 12103C274JAT2A for 25V or lower applications, and 12105C274JAT2A for applications requiring 50V or lower voltage ratings. Both parts are suitable for general purpose applications across the full operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the 12105C274JAT2A (50V) be used in place of the 12103C274JAT2A (25V)?

A: Yes. The 12105C274JAT2A is a direct substitute with identical capacitance, tolerance, temperature coefficient, and physical dimensions. The higher voltage rating (50V vs 25V) does not affect compatibility in circuits designed for 25V operation.

Q: Can the 12103C274JAT2A (25V) be used in place of the 12105C274JAT2A (50V)?

A: No. The 12103C274JAT2A has a lower voltage rating and cannot be substituted in circuits requiring 50V rated components.

Q: Are the physical footprints identical?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) and 0.037" maximum thickness. No PCB layout modifications are required when substituting between these parts.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the 12103C274JAT2A and 12105C274JAT2A are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
