Equivalent & Substitute Parts for 0508ZC105MAT9W

Part Overview

The 0508ZC105MAT9W is a 1 µF ceramic capacitor rated at 10V with X7R temperature coefficient, manufactured by KYOCERA AVX. This multilayer ceramic capacitor (MLCC) is designed for bypass and decoupling applications in surface mount configurations. The part features low ESL (reverse geometry) construction and operates across -55°C to 125°C. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), substitute parts are identified to provide design flexibility, inventory alternatives, or tolerance upgrades while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0508ZC105MAT9W is determined by the following critical parameters:

• Capacitance Value: Must be 1 µF (exact match required)
• Voltage Rating: Must be 10V or higher (equal or greater)
• Temperature Coefficient: Must be X7R (ensures stable capacitance across operating temperature range)
• Package / Case: Must be 0508 (1220 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part KGL21DR71A105KU meets all these criteria. The primary difference is tolerance specification: the main part carries ±20% tolerance, while the substitute offers ±10% tolerance. This represents a tolerance upgrade with no degradation of electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 0508ZC105MAT9W and KGL21DR71A105KU are active products manufactured by KYOCERA AVX with identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Both parts maintain MSL 1 (unlimited) moisture sensitivity rating and are suitable for bypass and decoupling applications.

The KGL21DR71A105KU offers improved tolerance specification (±10% versus ±20%), providing tighter capacitance control for applications requiring higher precision. Both parts are electrically and mechanically interchangeable within the specified operating parameters. Selection between these parts should be based on tolerance requirements, packaging format availability (the substitute is supplied in Tape & Reel format), and inventory considerations.

Frequently Asked Questions (FAQ)

Q: Can KGL21DR71A105KU replace 0508ZC105MAT9W in existing designs?

A: Yes. Both parts share identical capacitance (1 µF), voltage rating (10V), temperature coefficient (X7R), package dimensions (0508 / 1220 Metric), and operating temperature range (-55°C to 125°C). The substitute features improved tolerance (±10% versus ±20%), which represents an upgrade with no performance degradation.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. The 0508ZC105MAT9W carries ±20% tolerance, while the KGL21DR71A105KU carries ±10% tolerance. All other electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 0508 (1220 Metric) package with dimensions of 0.050" L x 0.079" W (1.27mm x 2.00mm) and maximum thickness of 0.040" (1.02mm). They are mechanically interchangeable on PCBs designed for this package.

Q: What packaging formats are available?

A: The 0508ZC105MAT9W is available in standard packaging, while the KGL21DR71A105KU is supplied in Tape & Reel (TR) format. Verify packaging requirements for your assembly process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, classified as EAR99 for export, and carry HTSUS code 8532.24.0020. Both maintain MSL 1 (unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably in high-precision applications?

A: The KGL21DR71A105KU is preferred for applications requiring tighter capacitance tolerance due to its ±10% specification compared to the ±20% tolerance of the 0508ZC105MAT9W. Both parts maintain stable performance across the -55°C to 125°C operating range with X7R temperature coefficient.
