Substitute Part Grouping Explanation

Substitute parts for the CDR03BX683AKUSAR are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

• Identical capacitance value: 0.068 µF
• Identical tolerance: ±10%
• Identical rated voltage: 50V
• Identical temperature coefficient: BX
• Identical operating temperature range: -55°C to 125°C
• Identical mounting type: Surface Mount, MLCC
• Identical package designation: 1808 (4520 Metric)
• Identical physical dimensions: 0.180" L x 0.080" W (4.57mm x 2.03mm)
• Identical thickness: 0.080" (2.03mm)
• Identical series classification: Military, MIL-PRF-55681, CDR03
• Identical failure rate: S (0.001%)
• Identical moisture sensitivity level: 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The CDR03BX683AKWSAT is a direct parametric equivalent to the CDR03BX683AKUSAR. Both parts are manufactured by Vishay Vitramon, maintain active product status, and comply with MIL-PRF-55681 military specifications. The parts are electrically and mechanically identical across all critical parameters including capacitance, voltage rating, temperature coefficient, operating temperature range, package dimensions, and failure rate classification.

The primary distinction between these parts is packaging format: the CDR03BX683AKUSAR is supplied in bulk packaging, while the CDR03BX683AKWSAT is supplied in cut tape (CT) format. Both packaging formats are suitable for automated assembly processes. The CDR03BX683AKWSAT currently has higher inventory availability (3425 units versus 1038 units), which may provide supply chain advantages for high-volume production requirements.

Both parts carry identical RoHS non-compliance status and moisture sensitivity level (MSL 1 - Unlimited), indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can CDR03BX683AKWSAT be used as a direct replacement for CDR03BX683AKUSAR?

A: Yes. The CDR03BX683AKWSAT is a parametric equivalent with identical electrical specifications (0.068 µF, ±10%, 50V, BX temperature coefficient), identical mechanical dimensions (1808 package, 4.57mm x 2.03mm x 2.03mm), and identical military-grade performance characteristics (MIL-PRF-55681, failure rate S). The parts are interchangeable in all applications.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging contains loose components, while cut tape (CT) packaging supplies components on continuous tape in specified quantities per reel. Cut tape format is optimized for automated pick-and-place assembly equipment. Both formats contain identical components; the difference is only in delivery and handling format.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical compliance status: RoHS non-compliant, ECCN EAR99, HTSUS 8532.24.0020, and MSL 1 (Unlimited). Both are certified to MIL-PRF-55681 military specifications with identical failure rate classification (S - 0.001%).

Q: Which part should be selected for new designs?

A: Selection between CDR03BX683AKUSAR and CDR03BX683AKWSAT depends on procurement and assembly requirements. For automated assembly processes, cut tape (CT) packaging of CDR03BX683AKWSAT is standard. For manual assembly or specific inventory management needs, bulk packaging of CDR03BX683AKUSAR may be appropriate. Both parts deliver identical performance.

Q: Are there any temperature or environmental performance differences?

A: No. Both parts operate identically across the -55°C to 125°C temperature range with identical BX temperature coefficient characteristics. Moisture sensitivity level (MSL 1 - Unlimited) is identical, requiring no special environmental controls during storage or assembly.
