GCM155R71H271KA37J Equivalent & Substitute Parts

Part Overview

The GCM155R71H271KA37J is a 270 pF ceramic capacitor manufactured by Murata Electronics, rated for 50V operation with X7R temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) in 0402 (1005 Metric) package format is designed for automotive applications and maintains Active product status. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory constraints require component alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GCM155R71H271KA37J are qualified based on strict equivalence across all critical electrical and mechanical parameters. Substitution eligibility requires exact matching of the following parameters:

• Capacitance value: 270 pF
• Tolerance: ±10%
• Voltage rating: 50V
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 125°C
• Package format: 0402 (1005 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Thickness: 0.022" (0.55mm) maximum
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

All identified substitute parts meet these criteria and are sourced from active product lines with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—GCM155R71H271KA37J, GCM155R71H271KA37D, and AC0402KRX7R9BB271—are functionally equivalent and maintain Active product status with full automotive compliance certification (AEC-Q200). Selection between these parts should be based on:

Inventory Availability: GCM155R71H271KA37J maintains the highest inventory level at 45,456 pieces. GCM155R71H271KA37D provides 7,887 pieces, and AC0402KRX7R9BB271 offers 10,030 pieces.

Manufacturer Preference: Both Murata variants (GCM155R71H271KA37J and GCM155R71H271KA37D) are from the same manufacturer and series (GCM), differing only in packaging designation suffix. The YAGEO variant (AC0402KRX7R9BB271) represents an alternative manufacturer source while maintaining identical electrical and mechanical specifications.

Regulatory Compliance: All three parts satisfy ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity requirements, making them suitable for automotive applications without additional qualification steps.

Frequently Asked Questions (FAQ)

Q: Can GCM155R71H271KA37D be used as a direct replacement for GCM155R71H271KA37J?

A: Yes. Both parts are manufactured by Murata Electronics within the GCM series and share identical electrical specifications (270 pF, ±10%, 50V, X7R), operating temperature range (-55°C to 125°C), package format (0402/1005 Metric), and physical dimensions. The suffix difference (KA37D versus KA37J) reflects packaging designation only and does not affect functional performance.

Q: Is the YAGEO AC0402KRX7R9BB271 suitable for automotive applications?

A: Yes. The AC0402KRX7R9BB271 carries AEC-Q200 automotive rating certification identical to the Murata parts and maintains all required compliance certifications (ROHS3, REACH unaffected). It is qualified for the same operating temperature range and environmental conditions.

Q: What are the critical parameters that must match for substitution?

A: Substitution requires exact matching of capacitance (270 pF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), package format (0402/1005 Metric), and physical dimensions (0.039" L x 0.020" W, 0.022" max thickness). All three parts meet these criteria.

Q: Are there any differences in moisture sensitivity or handling requirements?

A: No. All three parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage, handling, or assembly.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical package format (0402), mounting type (Surface Mount, MLCC), and physical dimensions ensure mechanical and electrical interchangeability in PCB assembly processes without design modifications or equipment reconfiguration.
