CDR01BP330BJMSAT Equivalent & Substitute Parts

Part Overview

The CDR01BP330BJMSAT is a 33 pF ceramic capacitor rated at 100V with BP temperature coefficient, manufactured by Vishay Vitramon under the military-grade CDR01 series (MIL-PRF-55681). This surface-mount multilayer ceramic capacitor (MLCC) in 0805 package is designed for high-reliability applications requiring stable performance across -55°C to 125°C operating range. The part maintains active product status with 1039 units in current inventory. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR01BP330BJMSAT is determined by the following critical parameters:

• Capacitance Value: Must be 33 pF (exact match required)
• Voltage Rating: Must be 100V or higher (equal or greater)
• Temperature Coefficient: Must be BP (identical)
• Operating Temperature Range: Must cover -55°C to 125°C minimum
• Package / Case: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Military Grade Compliance: Must meet MIL-PRF-55681 standard

The identified substitute CDR31BP330BFUS7185 (KEMET) satisfies all critical substitution parameters. While tolerance differs (±1% versus ±5%), this represents an upgrade in precision and does not prevent functional substitution. Physical dimensions show minor variations within acceptable tolerances for the 0805 package class.

Engineering Selection Recommendations

CDR01BP330BJMSAT (Primary Part)

• Recommended for new designs and applications where Vishay Vitramon sourcing is established
• Active product status with confirmed inventory availability (1039 units)
• RoHS3 compliant, supporting environmental and regulatory requirements
• ±5% tolerance suitable for non-critical frequency or filtering applications

CDR31BP330BFUS7185 (Substitute Part)

• Qualified alternative when CDR01BP330BJMSAT supply is constrained
• Tighter tolerance specification (±1%) provides improved precision for applications requiring closer capacitance control
• Active product status with adequate inventory (1266 units)
• Note: RoHS non-compliant status and REACH Affected designation require compliance verification in target application and region
• Tape & Reel packaging supports automated assembly processes

Both parts meet MIL-PRF-55681 military-grade requirements and maintain identical failure rate specifications. Selection between primary and substitute should account for compliance requirements, packaging format, and tolerance specifications relevant to the end application.

Frequently Asked Questions (FAQ)

Q: Can CDR31BP330BFUS7185 be used as a direct replacement for CDR01BP330BJMSAT?

A: Yes, CDR31BP330BFUS7185 is electrically and mechanically compatible. Both parts share identical capacitance (33 pF), voltage rating (100V), temperature coefficient (BP), operating temperature range (-55°C to 125°C), and 0805 package specification. The substitute offers improved tolerance (±1% versus ±5%). Compliance verification is required due to RoHS and REACH status differences.

Q: What are the physical dimension differences between these parts?

A: Both parts conform to 0805 (2012 Metric) package specification. Minor dimensional variations exist: CDR01BP330BJMSAT measures 2.03mm L × 1.27mm W × 1.40mm thickness; CDR31BP330BFUS7185 measures 2.00mm L × 1.25mm W × 1.30mm thickness. These variations fall within standard 0805 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Are there any compliance considerations when substituting these parts?

A: CDR01BP330BJMSAT is RoHS3 compliant. CDR31BP330BFUS7185 is RoHS non-compliant and REACH Affected. Applications subject to RoHS or REACH regulations must verify compliance requirements before substitution. Both parts carry EAR99 export classification and identical HTSUS codes.

Q: What is the difference in tolerance between these parts, and does it matter?

A: CDR01BP330BJMSAT specifies ±5% tolerance; CDR31BP330BFUS7185 specifies ±1% tolerance. The substitute provides tighter capacitance control. For applications where capacitance precision is critical (resonant circuits, precision filters), the ±1% tolerance may be advantageous. For general filtering or coupling applications, both tolerances are functionally equivalent.

Q: Which packaging format should I select?

A: CDR01BP330BJMSAT packaging is not specified in available data. CDR31BP330BFUS7185 is supplied in Tape & Reel (TR) format, supporting automated pick-and-place assembly. Confirm packaging requirements with your assembly process before final part selection.

Q: Do both parts meet military-grade specifications?

A: Yes. Both CDR01BP330BJMSAT and CDR31BP330BFUS7185 are manufactured to MIL-PRF-55681 military standard and maintain identical S-class failure rate specifications (0.001%). Both support high-reliability applications with unlimited moisture sensitivity level (MSL 1).
