Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR01BX472AMZSAT is determined by the following criteria:

Primary Matching Parameters (Non-Negotiable):

• Capacitance: 4700 pF (exact match required)
• Temperature Coefficient: BX (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Military Qualification: MIL-PRF-55681 series (exact match required)

Allowable Variation Parameters:

• Voltage Rating: May be equal to or higher than 50V
• Tolerance: May be tighter (lower) than ±20%
• Manufacturer: Alternative qualified manufacturers permitted
• Packaging Format: Tape & Reel acceptable as alternative to standard packaging

All identified substitute parts meet these criteria and maintain the same failure rate classification (S, 0.001%) and high-reliability application suitability.

Parameter Comparison

Engineering Selection Recommendations

CDR01BX472AKUS7185 (KEMET): This substitute maintains identical voltage rating (50V) and package specifications as the main part while offering improved tolerance (±10% versus ±20%). It is qualified to MIL-PRF-55681 CDR01 series and maintains active product status. Selection is appropriate for applications where tighter capacitance tolerance is beneficial and voltage rating requirements remain at 50V.

CDR31BX472BKUS (KEMET): This substitute provides voltage rating upgrade to 100V while maintaining the same package and temperature coefficient. Tolerance is improved to ±10%. It is qualified to MIL-PRF-55681 CDR31 series and maintains active product status. Selection is appropriate for applications where higher voltage margin is required or where circuit design permits higher voltage-rated components.

CDR31BX472BKWSAJ (Vishay Vitramon): This substitute provides voltage rating upgrade to 100V with improved tolerance (±10%) and maintains manufacturer continuity with the main part. It is qualified to MIL-PRF-55681 CDR31 series and maintains active product status. Highest inventory availability (5866 units) supports supply chain continuity. Selection is appropriate for applications requiring voltage upgrade with manufacturer consistency.

All substitute parts maintain MIL-PRF-55681 military qualification, active product status, and S-class failure rate specification. Selection among substitutes should be based on specific circuit voltage requirements and tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can CDR31 series parts substitute for CDR01 series parts? A: Yes, when all other parameters match. The CDR31 series represents an upgraded military qualification level within MIL-PRF-55681. CDR31 parts with 100V rating are direct substitutes for CDR01 parts with 50V rating when circuit design permits higher voltage-rated components. Voltage derating improves reliability margins.

Q: What is the significance of tolerance improvement from ±20% to ±10%? A: Tighter tolerance (±10%) provides more precise capacitance values, reducing circuit performance variation. This is beneficial in applications with strict frequency response or filtering requirements. The main part's ±20% tolerance is acceptable for general-purpose applications; ±10% substitutes offer enhanced performance margin.

Q: Are Tape & Reel packaged parts compatible with standard packaging requirements? A: Tape & Reel (TR) packaging is a standard format for automated assembly processes. All substitute parts in TR packaging are mechanically and electrically identical to standard packaging variants. Selection depends on assembly process requirements and handling procedures.

Q: What does MIL-PRF-55681 qualification ensure? A: MIL-PRF-55681 is a military performance specification for fixed ceramic capacitors. All parts listed maintain this qualification, ensuring compliance with military reliability, environmental, and performance standards. Failure rate classification S (0.001%) is consistent across all parts.

Q: Can I use a 100V-rated capacitor in a 50V circuit? A: Yes. A 100V-rated capacitor is fully compatible in a 50V circuit. The higher voltage rating provides additional safety margin and typically improves component reliability through reduced electrical stress. Physical dimensions remain within 0805 package specifications.

Q: What is the difference between CDR01 and CDR31 base product numbers? A: Both are MIL-PRF-55681 qualified series. CDR31 represents a higher reliability classification within the military specification. Both maintain identical operating temperature ranges, package formats, and failure rate classifications for the 4700 pF BX configuration.
