Key Parameters

Substitute Part Grouping Explanation

Substitution for the CDR34BP472BKUSAB is determined by strict equivalence in the following critical parameters:

• Capacitance value: 4700 pF (exact match required)
• Voltage rating: 100V (equal or higher acceptable)
• Temperature coefficient: BP (exact match required)
• Operating temperature range: -55°C to 125°C (equal or wider acceptable)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Military series compliance: MIL-PRF-55681 (exact match required)
• Failure rate classification: S (0.001%) (equal or better acceptable)

The identified substitute CDR34BP472BJUS maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±5% versus ±10%), representing an upgrade path for applications requiring tighter capacitance control.

Parameter Comparison

Engineering Selection Recommendations

Both the CDR34BP472BKUSAB and CDR34BP472BJUS are active production parts meeting MIL-PRF-55681 military specifications with identical failure rate classifications. The CDR34BP472BJUS offers improved tolerance performance (±5% versus ±10%), making it suitable for applications requiring tighter capacitance control without compromising reliability or compliance. Both parts maintain MSL 1 moisture sensitivity rating and are classified under identical export control (EAR99) and tariff codes. Selection between these parts should be based on tolerance requirements specific to the application circuit design.

Frequently Asked Questions (FAQ)

Q: Can CDR34BP472BJUS replace CDR34BP472BKUSAB in existing designs?

A: Yes. The CDR34BP472BJUS maintains identical electrical ratings (4700 pF, 100V, BP temperature coefficient), operating temperature range (-55°C to 125°C), mechanical dimensions (1812 package), and military reliability specifications (MIL-PRF-55681, S-level failure rate). The improved tolerance (±5%) represents an upgrade path.

Q: What is the significance of the tolerance difference between ±10% and ±5%?

A: Tolerance defines the acceptable deviation of actual capacitance from the nominal 4700 pF value. The ±10% specification allows 4230–5170 pF, while ±5% allows 4465–4935 pF. Applications requiring tighter capacitance control benefit from the ±5% specification of the CDR34BP472BJUS.

Q: Are both parts suitable for the full military temperature range?

A: Yes. Both parts are rated for -55°C to 125°C operating temperature and comply with MIL-PRF-55681 military specifications, ensuring performance across the full military temperature envelope.

Q: Do package dimensions differ between these parts?

A: No. Both parts use the 1812 (4532 Metric) package with identical dimensions: 0.177" L × 0.126" W (4.50mm × 3.20mm) and 0.059" maximum thickness (1.50mm). They are mechanically interchangeable on PCB layouts.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.
