12065C274MAT2A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 12065C274MAT2A is a 0.27 µF ceramic capacitor manufactured by KYOCERA AVX, rated for 50V with X7R temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) in 1206 package format is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production and ROHS3 compliant. Substitute parts are necessary when the original part becomes unavailable, when alternative tolerance specifications are required, or when sourcing from multiple manufacturers is needed for supply chain resilience.

Substitute Part Grouping Explanation

Substitution of the 12065C274MAT2A is determined by strict equivalence in the following parameters:

Capacitance Value: 0.27 µF (exact match required)
Voltage Rating: 50V (exact match required)
Temperature Coefficient: X7R (exact match required)
Package Format: 1206 (3216 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)

Tolerance specifications may vary among substitute parts. The original part specifies ±20% tolerance. Substitute parts with tighter tolerances (±10% or ±5%) are electrically compatible and represent upgrades in precision. All identified substitutes maintain identical capacitance, voltage rating, temperature coefficient, and package specifications, ensuring direct functional equivalence in circuit applications.

Engineering Selection Recommendations

Primary Substitutes (Active Status):

The KYOCERA AVX parts 12065C274JAT2A and 12065C274KAT2A are direct substitutes from the same manufacturer with improved tolerance specifications (±5% and ±10% respectively). Both maintain active product status and identical physical and electrical characteristics to the original part.

The KEMET C1206C274K5RAC7800 and YAGEO CC1206KRX7R9BB274 are functionally equivalent alternatives from established manufacturers. Both are active products with ROHS3 compliance and identical core electrical specifications. The KEMET part exhibits a maximum thickness of 0.039" (1.00mm), while the YAGEO part has a maximum thickness of 0.075" (1.90mm). These dimensional variations must be evaluated against specific PCB layout constraints.

Secondary Substitute (Legacy Status):

The Murata Electronics GRM319R71H274KA01D is electrically equivalent but carries a "Not For New Designs" product status. This part is suitable only for replacement or repair of existing assemblies and should not be selected for new product development.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature range specifications, ensuring regulatory and environmental compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different tolerance specification?

A: Yes. The original 12065C274MAT2A specifies ±20% tolerance. Substitute parts with tighter tolerances (±10% or ±5%) are electrically compatible and provide improved precision. Tighter tolerance parts will not cause circuit malfunction in applications designed for the original ±20% specification.

Q: Are there physical dimension differences between substitute parts?

A: All substitute parts use the 1206 (3216 Metric) package format with identical length (0.126") and width (0.063") specifications. However, thickness varies: the original and most substitutes measure 0.037" to 0.037" (0.94mm to 0.95mm), while the KEMET part measures 0.039" (1.00mm) and the YAGEO part measures 0.075" (1.90mm). Verify PCB clearance specifications before selecting parts with increased thickness.

Q: Which substitute should I select for new product designs?

A: Select from parts with active product status: 12065C274JAT2A, 12065C274KAT2A, C1206C274K5RAC7800, or CC1206KRX7R9BB274. Avoid GRM319R71H274KA01D, which is designated "Not For New Designs."

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory compliance of the original 12065C274MAT2A.

Q: What is the difference between KYOCERA AVX substitute parts?

A: The three KYOCERA AVX alternatives differ only in tolerance specification: 12065C274MAT2A (±20%), 12065C274KAT2A (±10%), and 12065C274JAT2A (±5%). All other electrical and physical characteristics are identical. Selection depends on circuit tolerance requirements.
