Key Parameters

Substitute Part Grouping Explanation

Substitution of the TYC0402A180JHT is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 18 pF
• Tolerance: ±5%
• Voltage rating: 100V minimum
• Temperature coefficient: C0G/NP0 (ensures stable capacitance across temperature range)
• Operating temperature range: -55°C to 125°C minimum

Mechanical Parameters:

• Package type: 0402 (1005 Metric) surface mount
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Mounting compatibility: Surface mount, MLCC

Environmental & Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS compliance status

Substitute parts must match all electrical specifications, maintain identical package dimensions for PCB layout compatibility, and satisfy equivalent environmental compliance requirements. The GRM1555C2A180JA01D from Murata Electronics meets these substitution criteria.

Engineering Selection Recommendations

TYC0402A180JHT (TE Connectivity Passive Product)

Product Status: Obsolete. This part is no longer in active production. Continued sourcing is limited to existing inventory.

GRM1555C2A180JA01D (Murata Electronics)

Product Status: Not For New Designs. This substitute part is available with significantly higher inventory (171,927 pcs in stock versus 1,082 pcs for the original part). The GRM1555C2A180JA01D provides functional and mechanical equivalence with enhanced compliance status (ROHS3 Compliant versus RoHS Compliant) and REACH Unaffected designation.

For applications requiring the 18 pF, 100V, C0G/NP0 ceramic capacitor in 0402 package format, the GRM1555C2A180JA01D from Murata Electronics is the direct substitute. Both parts satisfy identical electrical specifications, occupy the same PCB footprint, and maintain equivalent environmental performance characteristics. Selection between these parts should be based on inventory availability and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the GRM1555C2A180JA01D be used as a direct replacement for the TYC0402A180JHT?

A: Yes. Both parts are 18 pF, ±5%, 100V ceramic capacitors with C0G/NP0 temperature coefficient in 0402 (1005 Metric) package. Electrical specifications, operating temperature range, and physical dimensions are identical. PCB layout and assembly processes require no modification.

Q: What is the significance of the C0G/NP0 temperature coefficient designation?

A: C0G and NP0 are equivalent designations indicating zero temperature coefficient. Capacitance remains stable across the -55°C to 125°C operating temperature range, with negligible drift. This characteristic is critical for precision analog circuits, timing networks, and RF applications where capacitance stability is required.

Q: Are there packaging differences between the TYC0402A180JHT and GRM1555C2A180JA01D?

A: The TYC0402A180JHT packaging format is not specified in available data. The GRM1555C2A180JA01D is supplied in Tape & Reel (TR) format. Both parts use identical 0402 (1005 Metric) surface mount package dimensions (0.039" L x 0.020" W). Tape & Reel packaging is standard for automated assembly processes and does not affect component performance or PCB compatibility.

Q: What is the Moisture Sensitivity Level (MSL) rating, and why is it important?

A: Both parts carry MSL 1 (Unlimited) rating, indicating the component can be stored indefinitely without moisture absorption concerns. No baking or special moisture control procedures are required prior to soldering. This simplifies inventory management and reduces production constraints.

Q: How do the RoHS compliance statuses differ?

A: The TYC0402A180JHT is RoHS Compliant (RoHS 2 Directive). The GRM1555C2A180JA01D is ROHS3 Compliant, representing compliance with the more recent RoHS 3 Directive (2015/863/EU). ROHS3 Compliant status satisfies all RoHS 2 requirements and includes additional restricted substance limitations. Both parts are suitable for applications requiring RoHS compliance.

Q: What does "Not For New Designs" status mean for the GRM1555C2A180JA01D?

A: "Not For New Designs" indicates the manufacturer is not recommending this part for new product development, though it remains available for existing applications and legacy system support. For new designs, Murata may recommend alternative part numbers within the GRM series. However, for direct substitution of the obsolete TYC0402A180JHT, the GRM1555C2A180JA01D provides full functional equivalence.

Q: Are there any thermal or frequency performance differences between these parts?

A: No thermal or frequency performance data is provided in the component specifications. Both parts are rated for identical operating temperature range (-55°C to 125°C) and carry identical C0G/NP0 temperature coefficient designation, indicating equivalent thermal stability. For applications requiring specific frequency response or thermal performance characteristics, detailed datasheets from TE Connectivity and Murata Electronics should be consulted.
