Product Status Considerations: The TMF316AB7475KLHT carries "Not For New Designs" status and should be used only for legacy system support or replacement applications. All other substitute parts carry "Active" product status and are suitable for new designs.
Packaging Format Selection:
- Tape & Reel (TR) format: MBAST31LAB7475KTNA01, TMF316AB7475KLHT, CL31B475KAHVPJE, CL31B475KAHVPNE, GCM31CR71E475KA55K, KGM31HR71E475KL
- Cut Tape (CT) & Digi-Reel® format: C1206C475K3RACAUTO, CGA5L1X7R1E475K160AC, GCM31CR71E475KA55L, C1206C475K3RAC7800, C3216X7R1E475K160AC
Physical Constraint: The KGM31HR71E475KL has a maximum thickness of 0.075" (1.90mm) compared to 0.071" (1.80mm) for all other parts. Verify PCB assembly clearance before selection if space constraints exist.
Frequently Asked Questions (FAQ)
Q: Can I substitute MBAST31LAB7475KTNA01 with any of the listed parts?
A: Yes, all listed parts are electrically and mechanically equivalent. They share identical capacitance (4.7 µF), voltage rating (25V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), package type (1206/3216 Metric), and moisture sensitivity level (MSL 1). Selection depends on application requirements, packaging format preference, and certification needs.
Q: What is the difference between Upgrade and Parametric Equivalent parts?
A: Upgrade parts include AEC-Q200 automotive certification and are designated for automotive, SMPS filtering, bypass, or decoupling applications. Parametric Equivalent parts match all core electrical and mechanical specifications but may lack automotive certification. Both categories are functionally interchangeable for the specified parameters.
Q: Does the packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) affect electrical performance?
A: No. Packaging format affects only the delivery and handling method during manufacturing. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats contain identical components with identical electrical characteristics. Selection is based on manufacturing equipment compatibility and inventory management requirements.
Q: Is the KGM31HR71E475KL thickness difference significant?
A: The KGM31HR71E475KL has a maximum thickness of 0.075" (1.90mm) versus 0.071" (1.80mm) for other parts. This 0.004" (0.10mm) difference is within typical PCB assembly tolerances but should be verified if the application has strict height constraints or uses automated placement equipment with tight clearance specifications.
Q: Can I use TMF316AB7475KLHT for new designs?
A: TMF316AB7475KLHT carries "Not For New Designs" product status. It is suitable only for legacy system support, replacement applications, or continuation of existing production runs. For new designs, select from parts with "Active" product status: C1206C475K3RACAUTO, CGA5L1X7R1E475K160AC, CL31B475KAHVPJE, CL31B475KAHVPNE, GCM31CR71E475KA55K, GCM31CR71E475KA55L, KGM31HR71E475KL, C1206C475K3RAC7800, or C3216X7R1E475K160AC.
Q: Which substitute part has the highest inventory availability?
A: GCM31CR71E475KA55K (Murata Electronics) has the highest inventory with 710,930 pieces available. GCM31CR71E475KA55L (Murata Electronics) has 67,400 pieces. CGA5L1X7R1E475K160AC (TDK Corporation) has 179,390 pieces. These high-availability parts are suitable for volume production requirements.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the compliance level of the primary part MBAST31LAB7475KTNA01. All parts are lead-free and meet RoHS3 requirements.
Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?
A: MSL 1 indicates Moisture Sensitivity Level 1 with unlimited shelf life. These components do not require special moisture control during storage or handling. They can be stored at room temperature without desiccant packaging and have no expiration date for moisture-related degradation.
