GCQ1555C1HR80DB01D Equivalent & Substitute Parts

Part Overview

The GCQ1555C1HR80DB01D is a 0.8 pF ceramic capacitor manufactured by Murata Electronics, designed for RF, microwave, high-frequency, and automotive applications. This surface-mount MLCC (multilayer ceramic capacitor) in 0402 package form factor is rated at 50V with C0G/NP0 temperature coefficient and holds Active product status. Substitute parts are identified when design requirements allow tolerance relaxation, inventory constraints necessitate alternatives, or equivalent performance specifications are met within the same package and electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GCQ1555C1HR80DB01D is determined by strict adherence to the following parameters:

Fixed Parameters (Non-Negotiable):

• Capacitance: 0.8 pF
• Voltage Rating: 50V
• Temperature Coefficient: C0G, NP0
• Package / Case: 0402 (1005 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C
• Ratings: AEC-Q200
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameter (Allows Substitution):

• Tolerance: The main part specifies ±0.5pF. Substitute parts with tighter tolerances (±0.25pF, ±0.1pF, ±0.05pF) are acceptable as they represent improved precision while maintaining or exceeding the original specification.

All identified substitutes maintain identical capacitance, voltage rating, temperature coefficient, package dimensions, and compliance certifications. Tolerance variations reflect manufacturing precision improvements rather than functional deviations.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and ROHS3 compliance. Selection among these alternatives should be based on the following criteria derived from provided specifications:

Murata Electronics GCQ Series (GCQ1555C1HR80CB01D, GCQ1555C1HR80WB01D): These parts share identical base product number (GCQ1555C1H) and manufacturer lineage with the primary part. Both maintain AEC-Q200 automotive ratings and are suitable for RF, microwave, and high-frequency applications. GCQ1555C1HR80WB01D offers the highest inventory availability (67,748 units) with the tightest tolerance specification (±0.05pF).

YAGEO AC Series (AC0402BRNPO9BNR80): This alternative meets all fixed electrical and mechanical parameters with AEC-Q200 certification. Inventory availability is 10,774 units. This part is specified for automotive applications and maintains identical package dimensions and operating temperature range.

Selection should prioritize inventory availability, lead time requirements, and tolerance specifications appropriate to circuit design margins. All parts are electrically and mechanically interchangeable within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can GCQ1555C1HR80CB01D replace GCQ1555C1HR80DB01D in production?

A: Yes. GCQ1555C1HR80CB01D maintains identical capacitance (0.8 pF), voltage rating (50V), temperature coefficient (C0G, NP0), package (0402), and operating temperature range (-55°C ~ 125°C). The tolerance specification is tighter (±0.25pF versus ±0.5pF), which represents improved precision and is functionally compatible.

Q: What is the difference between C0G and NPO temperature coefficients?

A: C0G and NPO are equivalent designations for the same temperature coefficient characteristic. Both terms describe zero temperature coefficient behavior across the operating range. Murata uses C0G designation; YAGEO uses NPO designation. They are functionally identical.

Q: Is AC0402BRNPO9BNR80 from YAGEO suitable for automotive applications?

A: Yes. AC0402BRNPO9BNR80 carries AEC-Q200 automotive rating certification and is specified for automotive applications. It meets all electrical and mechanical parameters of the primary part.

Q: Why do substitute parts have different tolerance specifications?

A: Tolerance variations reflect different manufacturing precision grades within the same capacitance and voltage rating. Tighter tolerances (±0.05pF, ±0.1pF, ±0.25pF) represent higher precision manufacturing compared to the primary part (±0.5pF). All tolerances are acceptable substitutes when the circuit design accommodates the specified tolerance band.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All identified substitute parts are supplied in Tape & Reel (TR) packaging, matching the primary part's packaging format for automated assembly compatibility.

Q: What is Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life under standard storage conditions without requiring special moisture control measures. All identified parts share this specification.
