Substitute Part Grouping Explanation

Substitution of the LMK325BJ476MMHT is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Capacitance value: 47 µF
• Voltage rating: 10V
• Temperature coefficient: X5R
• Tolerance: ±20%
• Operating temperature range: -55°C ~ 85°C
• Package designation: 1210 (3225 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 3.20mm L x 2.50mm W x 2.70mm Max Thickness
• Automotive qualification: AEC-Q200
• Compliance standards: ROHS3, REACH Unaffected

The LMK325BJ476MMHP meets all these parameters and is classified as a parametric equivalent. Both parts belong to the Taiyo Yuden M series and share identical electrical specifications and physical form factors.

Parameter Comparison

Engineering Selection Recommendations

The LMK325BJ476MMHP is a direct parametric equivalent to the LMK325BJ476MMHT. Both parts are manufactured by Taiyo Yuden and carry identical electrical specifications, physical dimensions, and automotive qualifications. The primary distinction between these parts is their product status designation and current inventory availability.

Since the LMK325BJ476MMHT is marked "Not For New Designs," the LMK325BJ476MMHP serves as the appropriate substitute for ongoing production support and design continuity. Both parts satisfy AEC-Q200 automotive requirements, ROHS3 compliance, and REACH regulations. The interchangeability is complete across all electrical parameters, mechanical form factor, and environmental operating conditions.

Selection between these parts should be based on procurement availability and supply chain requirements rather than technical performance, as they are functionally identical.

Frequently Asked Questions (FAQ)

Q: Can the LMK325BJ476MMHP be used as a direct replacement for the LMK325BJ476MMHT?

A: Yes. The LMK325BJ476MMHP is a parametric equivalent with identical capacitance (47 µF), voltage rating (10V), temperature coefficient (X5R), tolerance (±20%), operating temperature range (-55°C ~ 85°C), package dimensions (1210 / 3225 Metric), and AEC-Q200 automotive qualification. No circuit modifications or design changes are required.

Q: Are there any physical differences between these parts?

A: No. Both parts share identical physical dimensions of 3.20mm length, 2.50mm width, and 2.70mm maximum thickness. Both are packaged in 1210 (3225 Metric) surface mount form factor and are supplied in Tape & Reel packaging.

Q: Do both parts meet automotive standards?

A: Yes. Both the LMK325BJ476MMHT and LMK325BJ476MMHP carry AEC-Q200 qualification and are suitable for automotive applications. Both are ROHS3 compliant and REACH unaffected.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates that the LMK325BJ476MMHT has been superseded in the manufacturer's product line. For new design implementations, the LMK325BJ476MMHP is the recommended part number. Existing designs using the LMK325BJ476MMHT can continue to use this part for ongoing production, or transition to the LMK325BJ476MMHP as supply permits.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling precautions are required during storage or assembly.

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

A: Yes. The identical 1210 (3225 Metric) package designation, surface mount configuration, and physical dimensions ensure that both parts are mechanically and electrically interchangeable on printed circuit boards without requiring any design modifications or assembly process changes.
