Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GCM188R71E562KA37D is determined by the following electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Capacitance: 5600 pF
• Tolerance: ±10%
• Voltage Rating: 25V
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Allowable Variation):

• Mounting Type: Surface Mount, MLCC
• Package Form Factor: Alternative surface mount packages acceptable if electrical specifications remain constant

Compliance Parameters (Must Match or Exceed):

• AEC-Q200 automotive qualification
• RoHS3 compliance
• Moisture Sensitivity Level 1

The GCM155R71E562KA37D qualifies as a substitute based on matching all electrical specifications and compliance requirements. The primary distinction is the package size reduction from 0603 (1608 Metric) to 0402 (1005 Metric), which represents a mechanical substitution suitable for space-constrained applications while maintaining identical electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The GCM155R71E562KA37D serves as the active product line equivalent to the GCM188R71E562KA37D. Both components maintain identical electrical specifications, including capacitance, voltage rating, temperature coefficient, and operating temperature range. Both are AEC-Q200 qualified for automotive applications and comply with ROHS3 requirements.

The primary distinction is product status: the GCM188R71E562KA37D is designated Not For New Designs, while the GCM155R71E562KA37D is Active. For new design implementations or component replenishment, the GCM155R71E562KA37D is the appropriate selection.

The GCM155R71E562KA37D employs a smaller 0402 (1005 Metric) package compared to the 0603 (1608 Metric) package of the main part. This size reduction is accompanied by proportional decreases in length, width, and thickness. PCB layout modifications are required to accommodate the smaller footprint. The substitute part is suitable for applications where board space optimization is beneficial or necessary.

Both components demonstrate identical moisture sensitivity classification (MSL 1, Unlimited) and are subject to the same handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the GCM155R71E562KA37D directly replace the GCM188R71E562KA37D in existing designs?

A: Electrical substitution is direct. The GCM155R71E562KA37D maintains identical capacitance, voltage rating, temperature coefficient, and operating temperature specifications. However, the smaller 0402 package requires PCB layout modification. Existing 0603 footprints cannot accommodate 0402 components without redesign.

Q: What are the physical differences between these two parts?

A: The GCM188R71E562KA37D uses a 0603 (1608 Metric) package measuring 0.063" L x 0.031" W with 0.035" maximum thickness. The GCM155R71E562KA37D uses a 0402 (1005 Metric) package measuring 0.039" L x 0.020" W with 0.022" maximum thickness. The substitute is approximately 38% smaller in length, 35% smaller in width, and 37% smaller in thickness.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the GCM188R71E562KA37D and GCM155R71E562KA37D carry AEC-Q200 qualification, confirming suitability for automotive applications. Both operate across the -55°C ~ 125°C temperature range required for automotive environments.

Q: Why is the GCM188R71E562KA37D marked as Not For New Designs?

A: The Not For New Designs designation indicates that Murata has transitioned this component to end-of-life status. The GCM155R71E562KA37D represents the active product line continuation with identical electrical specifications. New designs should incorporate the GCM155R71E562KA37D.

Q: Do both parts have the same compliance certifications?

A: Yes. Both components are ROHS3 compliant, carry AEC-Q200 automotive qualification, and maintain Moisture Sensitivity Level 1 (Unlimited). Both are subject to identical environmental and handling requirements.

Q: What inventory considerations apply to these parts?

A: The GCM188R71E562KA37D has 839 pieces in stock but is not recommended for new designs. The GCM155R71E562KA37D has 26,893 pieces in stock and is the active product. For ongoing production or new implementations, the GCM155R71E562KA37D offers superior supply chain availability.
