Equivalent & Substitute Parts for 08051A510MAT4A

Part Overview

The 08051A510MAT4A is a 51 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 100V with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) in 0805 (2012 Metric) package is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part maintains active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified to address inventory availability, lead time requirements, or specific tolerance and performance needs while maintaining electrical and mechanical compatibility within the same package and rating specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 08051A510MAT4A are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 51 pF (exact match required)
• Voltage rating: 100V (equal or higher acceptable)
• Temperature coefficient: C0G/NP0 (required for stability)
• Package: 0805 (2012 Metric) (physical and electrical compatibility)
• Mounting type: Surface Mount, MLCC
• Operating temperature range: -55°C to 125°C (minimum)

Allowable Variation:

• Tolerance: Tighter tolerances (±1%, ±5%) are acceptable substitutes for ±20% applications, as they represent improved precision within the same capacitance specification
• Physical dimensions: Minor variations within standard 0805 package specifications are acceptable
• Manufacturer: Different manufacturers producing equivalent specifications

The two qualified substitutes (C0805C510F1GAC7800 and C0805C510J1GAC7800) from KEMET meet all mandatory parameters and offer improved tolerance specifications while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both KEMET substitute parts maintain full compliance with ROHS3 and REACH requirements equivalent to the original 08051A510MAT4A. All three parts are active products with unlimited moisture sensitivity level (MSL 1), indicating no special storage or handling requirements.

The C0805C510F1GAC7800 (±1% tolerance) provides the highest precision specification and is suitable for applications requiring tighter capacitance control. The C0805C510J1GAC7800 (±5% tolerance) offers a balance between precision and cost, with tolerance performance between the original part and the highest-precision substitute.

Physical dimensions are equivalent across all three parts within standard 0805 package tolerances. The slightly reduced maximum thickness of the KEMET substitutes (0.035" versus 0.037") presents no compatibility issues for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can C0805C510F1GAC7800 or C0805C510J1GAC7800 be used as direct replacements for 08051A510MAT4A?

A: Yes. Both parts are direct substitutes. They share identical capacitance (51 pF), voltage rating (100V), temperature coefficient (C0G/NP0), package (0805), and operating temperature range (-55°C to 125°C). The tighter tolerances of the KEMET parts represent improved performance within the same electrical specification.

Q: What is the difference between the two KEMET substitutes?

A: The primary difference is tolerance specification. C0805C510F1GAC7800 offers ±1% tolerance, while C0805C510J1GAC7800 offers ±5% tolerance. Both maintain identical voltage rating, temperature coefficient, and package specifications. Selection depends on application precision requirements.

Q: Are there any physical compatibility concerns with the substitute parts?

A: No. All three parts conform to the 0805 (2012 Metric) package standard. Dimensional variations (2.01mm versus 2.00mm length, 0.037" versus 0.035" maximum thickness) fall within standard package tolerances and present no PCB assembly or mounting compatibility issues.

Q: Do the substitute parts require different handling or storage procedures?

A: No. All three parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating identical storage and handling requirements with no special precautions necessary.

Q: Are compliance certifications equivalent across all three parts?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications.
