Substitute Part Grouping Explanation

Substitute parts for the AMK325ABJ227MMHT are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 4V (exact match required)
• Temperature coefficient: X5R (exact match required)
• Tolerance: ±20% (exact match required)
• Operating temperature range: -55°C ~ 85°C (exact match required)

Mechanical Parameters:

• Package / Case: 1210 (3225 Metric) (exact match required)
• Physical dimensions: 0.126" L x 0.098" W x 0.110" Max Thickness (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)

Compliance Parameters:

• RoHS3 Compliance (required)
• Moisture Sensitivity Level 1 (required)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The GRM32ER60G227ME05L from Murata Electronics satisfies all specified parameters and qualifies as a functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The GRM32ER60G227ME05L from Murata Electronics is a direct parametric equivalent to the AMK325ABJ227MMHT. Both components share identical electrical specifications, mechanical dimensions, and compliance certifications. The primary distinction is product status: the Taiyo Yuden part is designated "Not For New Designs," while the Murata part maintains "Active" status.

For applications currently using the AMK325ABJ227MMHT, the GRM32ER60G227ME05L provides equivalent performance with the advantage of ongoing manufacturer support and supply chain availability. Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

The substitution is electrically and mechanically transparent, requiring no circuit redesign or board layout modification. Pin-to-pin compatibility and identical package footprints ensure direct replacement capability in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the GRM32ER60G227ME05L be used as a direct replacement for the AMK325ABJ227MMHT?

A: Yes. Both parts are parametric equivalents with identical capacitance (220 µF), voltage rating (4V), temperature coefficient (X5R), tolerance (±20%), operating temperature range (-55°C ~ 85°C), package format (1210 / 3225 Metric), and physical dimensions. No circuit modifications or board layout changes are required.

Q: What is the significance of the "Not For New Designs" status on the Taiyo Yuden part?

A: This designation indicates that Taiyo Yuden has discontinued active development and support for the AMK325ABJ227MMHT. Existing designs may continue to use this part, but new product development should transition to active alternatives such as the GRM32ER60G227ME05L.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the AMK325ABJ227MMHT and GRM32ER60G227ME05L are ROHS3 compliant, carry Moisture Sensitivity Level 1 rating, and are REACH unaffected. Compliance certifications are identical.

Q: Will the GRM32ER60G227ME05L fit the same PCB footprint as the AMK325ABJ227MMHT?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical physical dimensions: 0.126" L x 0.098" W x 0.110" maximum thickness. PCB footprints and assembly processes require no modification.

Q: Are there any electrical performance differences between these capacitors?

A: No. Both parts share identical electrical specifications: 220 µF capacitance, 4V voltage rating, X5R temperature coefficient, ±20% tolerance, and -55°C ~ 85°C operating temperature range. Electrical behavior in circuit applications is equivalent.

Q: What is the current inventory status for the substitute part?

A: The GRM32ER60G227ME05L is available with 5,357 pieces in stock as new original inventory, compared to 4,794 pieces for the Taiyo Yuden part. The Murata part offers improved supply chain availability due to its active product status.
