Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR01BX472AMZSAC 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)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Military Qualification: MIL-PRF-55681 series (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Failure Rate: S (0.001%) (exact match required)

Allowable Variation Parameters:

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

All identified substitute parts meet these criteria and are qualified for direct replacement in applications designed for the CDR01BX472AMZSAC.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified replacements for the CDR01BX472AMZSAC based on military specification compliance and electrical parameter matching.

CDR01BX472AKUS7185 (KEMET): This part maintains identical voltage rating (50V) and base series designation (CDR01) while offering improved tolerance (±10% versus ±20%). It is suitable for applications where the original Vishay Vitramon source is unavailable and equivalent performance characteristics are required.

CDR31BX472BKUS (KEMET): This part upgrades the voltage rating to 100V while maintaining all other critical parameters. The CDR31 series designation indicates enhanced voltage capability. This substitute is appropriate for applications where higher voltage margin is beneficial or where circuit redesign permits voltage rating increase.

CDR31BX472BKWSAJ (Vishay Vitramon): This part maintains the original manufacturer while upgrading to the CDR31 series with 100V rating and improved tolerance (±10%). This option provides continuity with the original manufacturer while offering enhanced electrical specifications.

All parts maintain active product status, MIL-PRF-55681 military qualification, S-level failure rate (0.001%), and unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can CDR01BX472AKUS7185 be used as a direct replacement for CDR01BX472AMZSAC?

A: Yes. Both parts share identical capacitance (4700 pF), voltage rating (50V), temperature coefficient (BX), package (0805), and military series designation (CDR01). The KEMET part offers tighter tolerance (±10% versus ±20%), which is an improvement. Tape & Reel packaging is functionally equivalent to standard packaging for surface mount assembly.

Q: What is the difference between CDR01 and CDR31 series parts?

A: The primary difference is voltage rating. CDR01 series is rated at 50V, while CDR31 series is rated at 100V. Both series comply with MIL-PRF-55681 and share identical capacitance, temperature coefficient, and operating temperature range. CDR31 parts are suitable for applications requiring higher voltage margin.

Q: Can a 100V-rated part replace a 50V-rated part?

A: Yes, in terms of electrical compatibility. A higher voltage rating provides additional safety margin and does not degrade performance in circuits designed for lower voltage operation. Physical dimensions remain within 0805 package specifications for all listed parts.

Q: Are there any compliance differences between the substitute parts?

A: All parts are RoHS non-compliant and carry ECCN EAR99 classification. KEMET parts include REACH Affected status, while Vishay Vitramon parts do not specify REACH status in the provided data. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: What is the significance of Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts carry this rating, meaning they can be stored and handled without special moisture control procedures.

Q: Are all substitute parts currently in stock?

A: Yes. CDR01BX472AKUS7185 has 1648 units, CDR31BX472BKUS has 1729 units, and CDR31BX472BKWSAJ has 5866 units available. The original CDR01BX472AMZSAC has 1048 units in stock.
