MLASH105SB7471MFNA01 Equivalent & Substitute Parts

Part Overview

The MLASH105SB7471MFNA01 is a 470 pF ceramic capacitor rated at 100V with X7R temperature coefficient in 0402 (1005 Metric) surface mount package manufactured by Taiyo Yuden. This multilayer ceramic capacitor (MLCC) is designed for medical and non-critical applications with unlimited moisture sensitivity level (MSL 1) and ROHS3 compliance. The part is currently in active production status with 726 units available in inventory.

Substitute parts are necessary when the original part becomes unavailable, when design requirements shift toward automotive-grade components, or when legacy product lines transition to newer manufacturing series while maintaining identical electrical and mechanical specifications.

Substitution Categories:

Upgrade Substitute: MAASH105SB7471MFCA01 represents an upgrade path within the Taiyo Yuden product family. This part maintains all electrical and mechanical specifications while adding AEC-Q200 automotive-grade qualification, making it suitable for automotive applications while remaining compatible with the original medical/non-critical application requirements.

Parametric Equivalent: HMK105B7471MV-F provides full parametric equivalence across all electrical and mechanical specifications. This part is designated "Not For New Designs" but remains available for legacy system support and maintenance applications where the original series is unavailable.

Parameter Comparison

Engineering Selection Recommendations

For Active Production and New Designs: Select MLASH105SB7471MFNA01 as the primary component. This part maintains active production status with established supply chain availability and is optimized for medical and non-critical applications.

For Automotive Applications: Select MAASH105SB7471MFCA01 as the preferred substitute. This part provides identical electrical and mechanical performance while adding AEC-Q200 automotive-grade qualification. The significantly higher inventory level (20,838 units) ensures supply continuity. This upgrade path is suitable when design requirements expand to include automotive-grade reliability standards.

For Legacy System Maintenance: HMK105B7471MV-F serves as a parametric equivalent for existing systems requiring component replacement. Although designated "Not For New Designs," this part maintains full electrical and mechanical compatibility with the original specification. Use this substitute only for maintenance and repair of established systems where the original part number is unavailable. The "Not For New Designs" status indicates this series is in end-of-life phase and should not be selected for new product development.

Compliance Verification: All three parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating. Selection between these parts does not introduce compliance risk when substituting within the same application category.

Frequently Asked Questions (FAQ)

Q: Can MAASH105SB7471MFCA01 be used as a direct replacement for MLASH105SB7471MFNA01 in medical applications?

A: Yes. MAASH105SB7471MFCA01 maintains all electrical and mechanical specifications required for medical applications. The addition of AEC-Q200 automotive qualification does not restrict use in medical applications; it represents an enhancement to the reliability profile. Both parts are ROHS3 compliant and MSL 1 rated.

Q: What is the significance of the "Not For New Designs" status on HMK105B7471MV-F?

A: This designation indicates the part is in end-of-life phase and Taiyo Yuden does not recommend its selection for new product development. However, the part remains available for maintenance and repair of existing systems. For new designs, select either MLASH105SB7471MFNA01 or MAASH105SB7471MFCA01.

Q: Are there physical compatibility differences between these three parts?

A: No. All three parts share identical package specifications: 0402 (1005 Metric) with dimensions of 0.039" L x 0.020" W and maximum thickness of 0.022". They are mechanically interchangeable on PCB assemblies designed for this package type.

Q: Can these parts be used interchangeably in SMPS filtering applications?

A: Yes. HMK105B7471MV-F is specifically noted for SMPS filtering applications, but all three parts maintain identical electrical characteristics (470 pF, 100V, X7R) and operating temperature range (-55°C to 125°C) required for this application. Selection should be based on availability and product status rather than application-specific performance differences.

Q: What inventory considerations should guide part selection?

A: MAASH105SB7471MFCA01 offers the highest inventory availability at 20,838 units, providing superior supply chain security. MLASH105SB7471MFNA01 maintains 726 units, and HMK105B7471MV-F has 3,380 units. For high-volume production, MAASH105SB7471MFCA01 is the preferred choice due to inventory depth.

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

A: No. All three parts are specified identically: 470 pF capacitance with ±20% tolerance, 100V voltage rating, X7R temperature coefficient, and -55°C to 125°C operating range. Electrical performance is equivalent across all three part numbers.

Q: What is the difference between the MLAS, MAAS, and M series designations?

A: These designations represent different product series within Taiyo Yuden's MLCC portfolio. MLAS is the current medical/non-critical series, MAAS is the automotive-qualified series, and M is a legacy series. All three series share identical electrical and mechanical specifications for this particular capacitor value, but differ in qualification levels and production status.
