MAASL31LAB7475MTNA01 Equivalent & Substitute Parts

Part Overview

The MAASL31LAB7475MTNA01 is a 4.7 µF ceramic capacitor rated at 10V with X7R temperature coefficient, manufactured by Taiyo Yuden in 1206 (3216 Metric) surface mount package. This part is currently Active and carries AEC-Q200 automotive qualification. Substitute parts are necessary when the primary part experiences supply constraints, inventory depletion, or when design requirements permit selection from alternative qualified sources while maintaining electrical and mechanical compatibility.

Operating Temperature Range	-55°C ~ 125°C	Must match or exceed
Mounting Type	Surface Mount, MLCC	Must match for assembly compatibility
RoHS Status	ROHS3 Compliant	Must maintain compliance
Moisture Sensitivity Level	1 (Unlimited)	Must match or be lower
AEC-Q200 Rating	Yes	Required for automotive applications

Substitute Part Grouping Explanation

Substitution eligibility for the MAASL31LAB7475MTNA01 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Capacitance: 4.7 µF (exact match required)
Voltage Rating: 10V (minimum requirement)
Temperature Coefficient: X7R (required for temperature stability characteristics)
Package / Case: 1206 (3216 Metric) (required for PCB footprint compatibility)
Mounting Type: Surface Mount, MLCC (required for assembly process compatibility)
Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
RoHS3 Compliance (required for regulatory compliance)
Moisture Sensitivity Level: 1 (Unlimited) (required for handling and storage compatibility)
AEC-Q200 Automotive Rating (required for automotive applications)

All substitute parts listed meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Engineering Selection Recommendations

Primary Selection (Active Status): The MAASL31LAB7475MTNA01 is the recommended choice for new designs due to its Active product status. This part maintains full manufacturer support and is qualified for ongoing production use.

Secondary Selection (Not For New Designs): The LMF316AB7475MLHT and LMK316B7475MLHT are electrically and mechanically equivalent substitutes. Both parts carry "Not For New Designs" status, indicating they are suitable for replacement, repair, or legacy system applications where the original part number is unavailable. These parts maintain full AEC-Q200 automotive qualification and ROHS3 compliance.

Differentiation: The LMK316B7475MLHT includes Ultra Low ESR as a specified feature, which may provide performance advantages in SMPS filtering applications. Both substitute parts support automotive and SMPS filtering applications, whereas the main part specifies automotive applications only.

All three parts are manufactured by Taiyo Yuden and share identical electrical specifications, dimensional characteristics, and regulatory compliance certifications, ensuring direct interchangeability within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can LMF316AB7475MLHT or LMK316B7475MLHT be used as direct replacements for MAASL31LAB7475MTNA01?

A: Yes. Both substitute parts meet all mandatory electrical and mechanical parameters: 4.7 µF capacitance, 10V voltage rating, X7R temperature coefficient, 1206 package, -55°C to 125°C operating range, AEC-Q200 automotive rating, ROHS3 compliance, and MSL 1 moisture sensitivity. Direct substitution is supported without design modification.

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

A: This status indicates the parts are no longer recommended for incorporation into new product designs. However, they remain fully qualified and suitable for replacement, repair, or legacy applications. The designation reflects manufacturer lifecycle management rather than technical deficiency.

Q: Are there dimensional differences between the main part and substitutes?

A: No. All three parts share identical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) with maximum thickness of 0.071" (1.80mm). PCB footprint compatibility is guaranteed.

Q: Does the Ultra Low ESR feature of LMK316B7475MLHT affect substitution compatibility?

A: No. Ultra Low ESR is an additional performance characteristic that does not affect basic electrical equivalence. The part remains a valid substitute. This feature may provide performance benefits in specific SMPS filtering applications but is not required for general substitution.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All three parts carry AEC-Q200 automotive qualification, meeting automotive industry reliability and quality standards.

Q: What is the moisture sensitivity implication for handling?

A: All parts are MSL 1 (Unlimited), indicating unlimited shelf life and no special moisture control requirements during storage or handling. Standard component storage conditions are sufficient.

Q: Are there compliance differences between the parts?

A: No. All parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications.
