Substitute Part Grouping Explanation

Substitution between CGA1A2X7R1H331M030BA and CGA1A2X7R1H331K030BA is based on the following criteria:

Electrical Compatibility Parameters:

• Identical capacitance value: 330 pF
• Identical voltage rating: 50V
• Identical temperature coefficient: X7R
• Identical operating temperature range: -55°C ~ 125°C

Mechanical Compatibility Parameters:

• Identical package format: 0201 (0603 Metric)
• Identical physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Identical thickness: 0.013" (0.33mm)
• Identical mounting type: Surface Mount, MLCC

Compliance & Certification:

• Both parts maintain AEC-Q200 automotive rating
• Both parts are ROHS3 compliant
• Both parts have MSL 1 (Unlimited) moisture sensitivity level

Tolerance Difference: The primary distinction between these parts is the capacitance tolerance specification. CGA1A2X7R1H331M030BA carries ±20% tolerance, while CGA1A2X7R1H331K030BA carries ±10% tolerance. This tolerance difference does not prevent substitution but indicates tighter capacitance control in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both CGA1A2X7R1H331M030BA and CGA1A2X7R1H331K030BA maintain Active product status with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on application tolerance requirements. The CGA1A2X7R1H331K030BA substitute part provides tighter capacitance tolerance (±10% versus ±20%), which may be advantageous in precision circuit applications where capacitance accuracy directly impacts circuit performance. Both parts are suitable for automotive environments with identical thermal and electrical ratings. Inventory availability and cost considerations may also influence part selection, as the substitute part shows significantly higher stock levels.

Frequently Asked Questions (FAQ)

Q: Can CGA1A2X7R1H331K030BA replace CGA1A2X7R1H331M030BA in existing designs?

A: Yes. Both parts share identical electrical specifications (330 pF, 50V, X7R), identical package dimensions (0201/0603 Metric), and identical automotive certifications (AEC-Q200). The substitute part features improved tolerance (±10% versus ±20%), making it a direct functional replacement.

Q: What is the significance of the tolerance difference between these parts?

A: Tolerance indicates the allowable deviation from the nominal 330 pF capacitance value. CGA1A2X7R1H331M030BA allows ±20% deviation (264-396 pF), while CGA1A2X7R1H331K030BA allows ±10% deviation (297-363 pF). Applications requiring tighter capacitance control benefit from the substitute part's narrower tolerance band.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and operate across the identical temperature range (-55°C ~ 125°C), confirming suitability for automotive environments.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts share identical Moisture Sensitivity Level 1 (Unlimited) ratings, indicating no special moisture control requirements during storage or handling.

Q: Is the 0201 package format the same as 0603 Metric?

A: Yes. The 0201 package designation and 0603 Metric designation refer to the same physical format with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm).
