Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBASS31LAB7473KTNA01 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 0.047 µF
• Tolerance: ±10%
• Voltage Rating: 630V
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C ~ 125°C
• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Thickness (Max): 0.071" (1.80mm)
• Packaging Format: Tape & Reel (TR)
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Substitute parts are categorized as Upgrade or Parametric Equivalent based on product status and additional certifications. Upgrade parts offer enhanced features or automotive-grade ratings. Parametric Equivalent parts provide functional equivalence without additional certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The MBASS31LAB7473KTNA01 remains the primary component choice due to Active product status and current inventory availability of 1156 units. This part is suitable for new designs and ongoing production.

Upgrade Alternatives (Active Status with Enhanced Ratings): GCJ31CR7LV473KW01K and GCJ31CR7LV473KW01L (Murata Electronics) are Active products with AEC-Q200 automotive-grade certification and Soft Termination features. These parts are suitable for applications requiring automotive compliance or boardflex-sensitive designs. GCJ31CR7LV473KW01K has 7822 units in stock, and GCJ31CR7LV473KW01L has 2981 units in stock.

Parametric Equivalent (Active Status): FM31X473K631EEG (Venatronics LLC) is an Active product providing parametric equivalence with 2912 units in stock. This part is suitable for general purpose applications where automotive certification is not required.

Legacy Alternative (Not For New Designs): SMK316AB7473KLHT (Taiyo Yuden) carries "Not For New Designs" status and should be used only for legacy system maintenance or replacement scenarios. This part has 5866 units in stock and includes AEC-Q200 certification.

Frequently Asked Questions (FAQ)

Q: Can GCJ31CR7LV473KW01K or GCJ31CR7LV473KW01L be used as direct replacements for MBASS31LAB7473KTNA01?

A: Yes. Both Murata parts meet all mandatory electrical and mechanical parameters: 0.047 µF capacitance, ±10% tolerance, 630V rating, X7R temperature coefficient, -55°C to 125°C operating range, 1206 package, and identical physical dimensions. Both are Active products with ROHS3 compliance and MSL 1 rating. The primary differences are manufacturer identity and additional AEC-Q200 automotive certification.

Q: What is the difference between GCJ31CR7LV473KW01K and GCJ31CR7LV473KW01L?

A: Both parts are functionally equivalent with identical electrical specifications, package dimensions, and certifications. The suffix difference (K versus L) indicates different manufacturing batches or date codes. Both are Active products suitable for new designs.

Q: Is FM31X473K631EEG suitable for automotive applications?

A: FM31X473K631EEG meets all parametric requirements for the 0.047 µF 630V X7R 1206 capacitor specification. However, it does not carry AEC-Q200 automotive certification. For automotive applications requiring formal qualification, GCJ31CR7LV473KW01K or GCJ31CR7LV473KW01L are recommended.

Q: Why is SMK316AB7473KLHT marked "Not For New Designs"?

A: SMK316AB7473KLHT carries legacy product status. While it meets all electrical and mechanical parameters and includes AEC-Q200 certification, the "Not For New Designs" designation indicates the manufacturer is phasing out this part number. It should be used only for replacement or maintenance of existing systems.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All identified substitute parts are supplied in Tape & Reel (TR) packaging format, matching the MBASS31LAB7473KTNA01 packaging specification.

Q: Do all parts have the same moisture sensitivity level?

A: Yes. All parts, including the main part and all substitutes, have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts have identical 1206 (3216 Metric) package dimensions (0.126" L x 0.063" W, 3.20mm x 1.60mm) and maximum thickness (0.071" / 1.80mm). They are mechanically and electrically interchangeable on PCB layouts designed for the MBASS31LAB7473KTNA01.
