GCM1885C1H4R9DA16D Equivalent & Substitute Parts

Part Overview

The GCM1885C1H4R9DA16D is a 4.9 pF ceramic capacitor manufactured by Murata Electronics, rated for 50V operation with C0G/NP0 temperature coefficient characteristics. This component is packaged in 0603 (1608 Metric) form factor and is designed for surface mount applications in automotive environments. The part carries AEC-Q200 automotive qualification and ROHS3 compliance status.

The product status is listed as "Not For New Designs," indicating that while the component remains available in inventory (726 pieces in stock), Murata has designated this part for legacy applications only. Identification of equivalent substitute parts is necessary for new design implementations and long-term supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GCM1885C1H4R9DA16D is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Capacitance value: 4.9 pF
• Voltage rating: 50V minimum
• Temperature coefficient: C0G/NP0

Compliance & Certification (Must Match):

• AEC-Q200 automotive qualification
• ROHS3 compliance
• Moisture Sensitivity Level: MSL 1

Mechanical Parameters (Flexible):

• Package form factor may differ (0603 vs. 0402)
• Physical dimensions and thickness may vary
• Tolerance specifications may be tighter

The identified substitute part GCM1555C1H4R9CA16D maintains electrical equivalence through identical capacitance, voltage rating, and temperature coefficient. Both parts share the same series designation (GCM), automotive qualification (AEC-Q200), and compliance certifications. The primary difference is the package size reduction from 0603 to 0402 form factor, which represents a design optimization rather than a functional limitation.

Parameter Comparison

Engineering Selection Recommendations

For New Design Implementation:

The GCM1555C1H4R9CA16D is the recommended selection for new designs. This part maintains full electrical equivalence to the GCM1885C1H4R9DA16D while offering active product status from Murata Electronics. The substitute part carries identical AEC-Q200 automotive qualification and ROHS3 compliance certifications, ensuring regulatory and quality requirements are met.

The transition from 0603 to 0402 package format represents a size reduction that provides design flexibility for space-constrained applications. The tighter tolerance specification (±0.25 pF versus ±0.5 pF) on the substitute part offers improved precision for frequency-critical circuits.

For Legacy System Maintenance:

The GCM1885C1H4R9DA16D remains available in current inventory (726 pieces) for applications requiring the original 0603 package form factor. The "Not For New Designs" designation does not affect functional performance or compliance status for existing systems.

Compliance Verification:

Both parts satisfy automotive-grade requirements through AEC-Q200 certification and maintain ROHS3 compliance with MSL 1 moisture sensitivity rating, indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the GCM1555C1H4R9CA16D be used as a direct replacement for the GCM1885C1H4R9DA16D?

A: Yes, from an electrical standpoint. Both parts have identical capacitance (4.9 pF), voltage rating (50V), and temperature coefficient (C0G/NP0). The primary consideration is the package size change from 0603 to 0402. PCB layout modifications are required to accommodate the smaller footprint.

Q: What is the significance of the "Not For New Designs" status on the GCM1885C1H4R9DA16D?

A: This designation indicates that Murata has transitioned this part to legacy status and recommends using the GCM1555C1H4R9CA16D for new product development. The original part remains functional and available but is not recommended for designs entering production.

Q: Are there tolerance differences between these parts?

A: Yes. The GCM1885C1H4R9DA16D has a tolerance of ±0.5 pF, while the GCM1555C1H4R9CA16D offers a tighter tolerance of ±0.25 pF. For applications requiring precise capacitance values, the substitute part provides superior tolerance performance.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the GCM1885C1H4R9DA16D and GCM1555C1H4R9CA16D carry AEC-Q200 automotive qualification and are ROHS3 compliant. They are suitable for automotive applications requiring these certifications.

Q: What are the physical footprint differences?

A: The GCM1885C1H4R9DA16D uses a 0603 (1608 Metric) package measuring 1.60mm x 0.80mm with 0.90mm maximum thickness. The GCM1555C1H4R9CA16D uses a 0402 (1005 Metric) package measuring 1.00mm x 0.50mm with 0.55mm maximum thickness. The substitute part is approximately 37% smaller in length and 38% smaller in width.

Q: Is special handling required for either part?

A: No. Both parts have MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control or baking procedures are required during storage or assembly.

Q: Can the GCM1555C1H4R9CA16D be used in existing PCB designs without modification?

A: No. The 0402 package requires a different PCB footprint than the 0603 package. PCB layout redesign is necessary to accommodate the smaller component size and pad configuration.
