Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LD032U1R0BAB2A is determined by the following mandatory parameters:

• Capacitance value: 1 pF (exact match required)
• Temperature coefficient: C0G or NP0 (equivalent designations)
• Package: 0603 (1608 Metric) surface mount
• Operating temperature range: -55°C to 125°C minimum
• Moisture sensitivity: MSL 1 or better
• Voltage rating: Equal to or greater than 200V

Two substitute parts meet these criteria. The KGQ15ACG2D1R0BT maintains identical electrical specifications with enhanced ESR performance characteristics. The CQ0603ARNPOYBN1R0 provides upgraded voltage rating (250V) and improved tolerance (±0.05pF) while maintaining all core compatibility parameters.

Parameter Comparison

Engineering Selection Recommendations

The KGQ15ACG2D1R0BT serves as a direct parametric equivalent to the LD032U1R0BAB2A with identical electrical specifications. This substitute is manufactured by the same supplier (KYOCERA AVX) and achieves ROHS3 compliance, addressing regulatory requirements where the original part does not. Selection of this part is appropriate for applications requiring equivalent performance with improved environmental compliance status.

The CQ0603ARNPOYBN1R0 functions as an upgrade option, providing increased voltage margin (250V versus 200V) and tighter tolerance (±0.05pF versus ±0.1pF). This YAGEO part maintains all core compatibility parameters while offering enhanced performance specifications. The upgrade is suitable for designs requiring additional voltage headroom or improved capacitance stability.

Both substitute parts maintain identical package geometry, mounting type, and thermal operating range, ensuring direct board-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can KGQ15ACG2D1R0BT be used as a direct replacement for LD032U1R0BAB2A?

A: Yes. Both parts share identical capacitance (1 pF), tolerance (±0.1pF), voltage rating (200V), temperature coefficient (C0G/NP0), and 0603 package specifications. The KGQ15ACG2D1R0BT is electrically and mechanically interchangeable.

Q: What is the primary difference between the two substitute parts?

A: The KGQ15ACG2D1R0BT maintains specification parity with the original part. The CQ0603ARNPOYBN1R0 provides upgraded voltage rating (250V) and improved tolerance (±0.05pF), making it suitable for designs requiring enhanced performance margins.

Q: Are there any package dimension differences between these parts?

A: All three parts use the 0603 (1608 Metric) package. Minor dimensional variations exist within standard tolerances (LD032U1R0BAB2A: 1.52mm × 0.76mm; CQ0603ARNPOYBN1R0: 1.60mm × 0.80mm), which remain within typical PCB pad design tolerances for this package class.

Q: Do the substitute parts meet RoHS requirements?

A: The LD032U1R0BAB2A is RoHS non-compliant. Both KGQ15ACG2D1R0BT and CQ0603ARNPOYBN1R0 are ROHS3 compliant, making them suitable for applications with RoHS regulatory requirements.

Q: What is the moisture sensitivity level for all three parts?

A: All parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can CQ0603ARNPOYBN1R0 be used in circuits designed for 200V operation?

A: Yes. The CQ0603ARNPOYBN1R0 is rated for 250V, which exceeds the 200V requirement. Higher voltage-rated capacitors operate safely at lower applied voltages.
