CDR12BG6R2ABUS Equivalent & Substitute Parts

Part Overview

The CDR12BG6R2ABUS is a 6.2 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 50V operation with a BG temperature coefficient. This component is part of the Military MIL-PRF-55681 CDR12 series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts with matching electrical and mechanical specifications is necessary for design continuity and procurement planning. Substitute parts must maintain identical capacitance, voltage rating, tolerance, package dimensions, and operating temperature range to ensure functional compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDR12BG6R2ABUS must satisfy the following mandatory electrical and mechanical criteria:

Capacitance value of 6.2 pF with tolerance of ±0.1pF ensures functional equivalence in circuit operation. Voltage rating of 50V or higher maintains design safety margins. Operating temperature range of -55°C to 125°C or wider ensures performance across specified environmental conditions. Package designation 0505 (1313 Metric) with surface mount MLCC mounting type ensures physical and electrical compatibility with existing PCB layouts. Moisture sensitivity level of 1 (Unlimited) or equivalent ensures handling and storage compatibility.

The identified substitute part 0505J0506P20BQT from Knowles Syfer meets all mandatory substitution criteria. While the temperature coefficient differs (C0G/NP0 versus BG), both coefficients are acceptable for this capacitance value and voltage rating within the specified operating temperature range. The substitute part maintains identical capacitance, tolerance, voltage rating, package dimensions, and MSL classification.

Parameter Comparison

Engineering Selection Recommendations

The 0505J0506P20BQT from Knowles Syfer is a direct electrical and mechanical substitute for the obsolete CDR12BG6R2ABUS. Both parts share identical capacitance, tolerance, voltage rating, operating temperature range, package dimensions, and MSL classification. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The substitute part offers improved compliance status: ROHS3 compliant versus RoHS non-compliant for the main part. Both parts maintain REACH Unaffected and EAR99 ECCN classifications. The substitute part's maximum thickness of 0.050" (1.27mm) is thinner than the main part's 0.057" (1.45mm), providing additional design flexibility for space-constrained applications.

Selection of the substitute part is appropriate for new designs and redesigns of existing applications using the CDR12BG6R2ABUS, particularly where RoHS compliance is required.

Frequently Asked Questions (FAQ)

Q: Can the 0505J0506P20BQT directly replace the CDR12BG6R2ABUS in existing designs?

A: Yes. Both parts maintain identical capacitance (6.2 pF), tolerance (±0.1pF), voltage rating (50V), operating temperature range (-55°C to 125°C), package designation (0505 / 1313 Metric), and physical dimensions (0.055" x 0.055" / 1.40mm x 1.40mm). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between BG and C0G/NP0 temperature coefficients?

A: Both BG and C0G/NP0 are temperature coefficient designations for ceramic capacitors. For the 6.2 pF capacitance value at 50V rating within the -55°C to 125°C operating range, both coefficients provide acceptable performance characteristics. The C0G/NP0 coefficient of the substitute part offers stable capacitance across the temperature range.

Q: Are there any physical dimension differences that affect PCB layout?

A: The substitute part has a maximum thickness of 0.050" (1.27mm) compared to the main part's 0.057" (1.45mm). This 0.007" (0.18mm) difference is negligible for standard PCB assembly and does not require layout modifications. The length and width dimensions remain identical at 0.055" x 0.055" (1.40mm x 1.40mm).

Q: Does the substitute part meet RoHS compliance requirements?

A: Yes. The 0505J0506P20BQT is ROHS3 compliant, whereas the CDR12BG6R2ABUS is RoHS non-compliant. For applications requiring RoHS compliance, the substitute part is the appropriate selection.

Q: What is the moisture sensitivity level (MSL) for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.
