EMK325AC6476MM-P Equivalent & Substitute Parts

Part Overview

The EMK325AC6476MM-P is a 47 µF, 16V ceramic capacitor in 1210 (3225 Metric) package manufactured by Taiyo Yuden. This multilayer ceramic capacitor (MLCC) is designed for SMPS filtering applications and features X6S temperature coefficient characteristics. The part is marked as "Not For New Designs," indicating it has been superseded in the product lifecycle. Identification of equivalent and substitute parts is necessary for legacy system support, inventory management, and design continuity where this component is already deployed.

Substitute Part Grouping Explanation

Substitution of the EMK325AC6476MM-P is determined by strict equivalence across the following parameters:

Critical Substitution Parameters:

Capacitance: 47 µF (exact match required)
Voltage Rating: 16V (exact match required)
Temperature Coefficient: X6S (exact match required)
Package / Case: 1210 (3225 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Tolerance: ±20% (exact match required)

Compliance Parameters:

RoHS Status: ROHS3 Compliant (all substitutes must maintain compliance)
Moisture Sensitivity Level: 1 (Unlimited) (all substitutes must maintain MSL rating)

All identified substitute parts meet these criteria. Substitution is valid based on parametric equivalence; packaging format differences (Cut Tape vs. Tape & Reel) do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

EMK325AC6476MM-T: This part is a direct parametric equivalent to EMK325AC6476MM-P with identical electrical and mechanical specifications. The only difference is packaging format (Tape & Reel vs. Cut Tape). Both parts carry "Not For New Designs" status. Selection between these two is determined by supply chain requirements and packaging handling capabilities.

MSASE32MAC6476MPNDT1: This part is a direct parametric equivalent with identical electrical and mechanical specifications. The MSASE32MAC6476MPNDT1 carries "Active" product status, indicating ongoing manufacturer support and availability. This part represents the current production alternative within the Taiyo Yuden product line for this capacitance, voltage, and package combination. All three parts maintain ROHS3 compliance and identical moisture sensitivity ratings.

Selection among these three parts should be based on:

Product lifecycle requirements (Active vs. Not For New Designs status)
Packaging format compatibility with assembly equipment
Inventory and supply chain considerations
Compliance certifications (all three are equivalent)

Frequently Asked Questions (FAQ)

Q: Can EMK325AC6476MM-T be used as a direct replacement for EMK325AC6476MM-P?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications, including capacitance (47 µF), voltage rating (16V), temperature coefficient (X6S), package dimensions (1210/3225 Metric), and operating temperature range (-55°C ~ 105°C). The only difference is packaging format (Cut Tape vs. Tape & Reel), which does not affect electrical performance or mechanical fit on the PCB.

Q: What is the difference between EMK325AC6476MM-P and MSASE32MAC6476MPNDT1?

A: Both parts are parametrically equivalent with identical electrical and mechanical characteristics. The primary difference is product status: EMK325AC6476MM-P is marked "Not For New Designs," while MSASE32MAC6476MPNDT1 is "Active." The MSASE32MAC6476MPNDT1 represents the current production part from Taiyo Yuden for this specification.

Q: Are all three parts suitable for SMPS filtering applications?

A: Yes. All three parts are specified for SMPS filtering applications and share identical electrical parameters required for this function, including the X6S temperature coefficient and 16V voltage rating.

Q: Does packaging format affect PCB assembly compatibility?

A: Packaging format (Cut Tape vs. Tape & Reel) affects supply chain handling and automated assembly equipment compatibility, but does not affect electrical performance or physical fit on the PCB. All three parts have identical dimensions and mounting characteristics.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, maintaining identical compliance status.

Q: What is the moisture sensitivity level for these parts?
