Electrical Parameters (Must Match Exactly):

• Capacitance: 0.33 µF
• Tolerance: ±10%
• Voltage Rating: 100V
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C to 125°C

Mechanical Parameters (Must Match Exactly):

• Package Type: 1206 (3216 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Maximum Thickness: 0.071" (1.80mm)

Compliance Parameters (Must Match or Exceed):

• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant or equivalent
• REACH Status: REACH Unaffected

All identified substitute parts meet these criteria and are direct functional replacements suitable for identical circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed are active production components with full regulatory compliance. Selection between the MLASH31LSB7334KTNA01 and its substitutes is based on availability, lead time, and sourcing requirements rather than electrical or mechanical differences.

MLASH31LSB7334KTNA01 (Taiyo Yuden): Primary choice for medical and non-critical applications. ROHS3 compliant with established supply chain for medical-grade applications.

GMC31X7R334K100NT (Cal-Chip Electronics): Direct parametric equivalent with highest current inventory (50,813 pcs). Suitable for general purpose applications with RoHS compliance. Appropriate for applications where medical-specific qualification is not required.

KGM31AR72A334KU (KYOCERA AVX): Direct parametric equivalent with ROHS3 compliance matching the primary part. Suitable for general purpose applications with equivalent regulatory standing to the Taiyo Yuden part.

All three parts are suitable for direct substitution in identical circuit designs without modification to PCB layout, assembly process, or electrical design parameters.

Frequently Asked Questions (FAQ)

Q: Can GMC31X7R334K100NT be used as a direct replacement for MLASH31LSB7334KTNA01?

A: Yes. Both parts share identical electrical specifications (0.33 µF, ±10%, 100V, X7R, -55°C to 125°C), mechanical dimensions (1206 package, 3.20mm x 1.60mm), and compliance ratings (MSL 1, REACH Unaffected). The parts are functionally interchangeable in circuit design and PCB assembly.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant?

A: ROHS3 Compliant indicates compliance with the third iteration of the Restriction of Hazardous Substances directive. RoHS Compliant indicates general RoHS compliance. Both meet regulatory requirements; ROHS3 represents the current standard. GMC31X7R334K100NT carries RoHS Compliant status while MLASH31LSB7334KTNA01 and KGM31AR72A334KU carry ROHS3 Compliant status.

Q: Are there any physical differences between these three parts?

A: No. All three parts have identical physical dimensions: 0.126" length x 0.063" width (3.20mm x 1.60mm) with maximum thickness of 0.071" (1.80mm). They are mechanically interchangeable on PCB layouts designed for 1206 (3216 Metric) surface mount packages.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. "Unlimited" means the component can be stored indefinitely without special moisture control measures, and no baking is required before soldering. All three parts carry this rating.

Q: Can these parts be used in medical applications?

A: The MLASH31LSB7334KTNA01 is specified for medical and non-critical applications. The GMC31X7R334K100NT and KGM31AR72A334KU are specified for general purpose applications. For medical device designs, use the Taiyo Yuden part or verify substitute parts against specific medical device qualification requirements.

Q: What is the operating temperature range for all three parts?

A: All three parts operate across -55°C to 125°C with X7R temperature coefficient, ensuring stable capacitance across this full range.

Q: Are these parts available in other package sizes?

A: The specifications provided cover only the 1206 (3216 Metric) package. Other package sizes may be available from these manufacturers but are not included in this equivalency reference.
