M30U474M5-F Equivalent & Substitute Parts

Part Overview

The M30U474M5-F is a 0.47 µF ceramic capacitor rated at 50V with Z5U temperature coefficient, manufactured by Cornell Dubilier Electronics (CDE) in radial through-hole configuration. This part is classified as obsolete, necessitating identification of active equivalent and substitute components for ongoing design support and procurement continuity. The Z5U temperature coefficient provides stable capacitance across the 10°C to 85°C operating range, making it suitable for general-purpose applications in legacy and current designs.

Engineering Selection Recommendations

For Direct Replacement (Equivalent Performance):

Select from the active KEMET or KYOCERA AVX parts listed in the direct substitute category when the application requires identical electrical and thermal characteristics to the M30U474M5-F. All direct substitutes maintain Z5U temperature coefficient performance and are ROHS3 compliant. KEMET C322C474M5U5TA and C330C474M5U5TA offer active product status with established supply chains. KYOCERA AVX SkyCap® SR series parts (SR215E474MAA, SR215E474MAR, SR305E474MAATR1, SR305E474MARTR1) provide alternative sourcing with equivalent specifications.

Packaging Considerations:

Bulk packaging: C322C474M5U5TA, C330C474M5U5TA, SR215E474MAA, SR215E474MAR, SR215E474MAT
Tape & Reel (TR) packaging: SR215E474MAATR1, SR305E474MAATR1, SR305E474MARTR1
Cut Tape (CT) packaging: SR215E474MARTR1

For Enhanced Performance (Upgrade Option):

The KEMET C330C474F5G5TA upgrade option is applicable when the design can accommodate tighter tolerance (±1%) and extended operating temperature range (-55°C ~ 125°C). This part maintains mechanical compatibility and RoHS3 compliance while providing superior capacitance stability through C0G/NP0 temperature coefficient. The upgrade is suitable for applications requiring improved performance margins or operation outside the standard 10°C ~ 85°C range.

Product Status Consideration:

All recommended direct substitutes carry active product status, ensuring long-term availability and supply continuity. The M30U474M5-F obsolete status necessitates transition to one of these active alternatives for new designs or ongoing production support.

Frequently Asked Questions (FAQ)

Q: Can I use the KEMET C330C474F5G5TA as a direct replacement for the M30U474M5-F?

A: The C330C474F5G5TA is mechanically compatible and meets the 0.47 µF, 50V, and lead spacing requirements. However, it differs in temperature coefficient (C0G/NP0 versus Z5U) and tolerance (±1% versus ±20%). It functions as an upgrade option with enhanced specifications rather than a direct equivalent. Use this part only if the application design permits the extended temperature range (-55°C ~ 125°C) and tighter tolerance.

Q: What is the difference between the KYOCERA AVX SR215E474MAA and SR305E474MAATR1?

A: Both parts are electrically identical (0.47 µF, 50V, Z5U). The SR215E474MAA has physical dimensions of 0.200" L x 0.125" W with 0.300" maximum seated height. The SR305E474MAATR1 has larger dimensions of 0.300" L x 0.150" W with 0.360" maximum seated height. The SR305E474MAATR1 is supplied in Tape & Reel packaging, while SR215E474MAA is supplied in bulk. Select based on PCB layout space constraints and procurement packaging requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts and the upgrade option carry RoHS3 compliance certification, meeting regulatory requirements for lead-free and restricted substance standards.

Q: What is the significance of lead style differences (Straight versus Formed Leads - Kinked)?

A: Lead style affects mechanical insertion into PCB holes. The M30U474M5-F features straight leads. Direct substitutes from KYOCERA AVX SkyCap® SR series use formed leads with kinked configuration, which may require different insertion tooling or manual handling. KEMET parts use formed leads without kinking. Verify PCB assembly equipment compatibility with the selected lead style before production transition.

Q: Can I mix different manufacturers' parts in the same PCB assembly?

A: Yes. All listed substitutes meet identical electrical specifications (0.47 µF, ±20%, 50V, Z5U) and mechanical requirements (0.200" lead spacing, through-hole radial). They are interchangeable from an electrical and functional standpoint. However, verify that your assembly process and quality control procedures accommodate multiple manufacturer sources if required.

Q: What packaging options are available for high-volume production?

A: Tape & Reel (TR) and Cut Tape (CT) packaging options are available from KYOCERA AVX (SR215E474MAATR1, SR305E474MAATR1, SR305E474MARTR1, SR215E474MARTR1) for automated assembly processes. KEMET and bulk-packaged KYOCERA AVX options are suitable for manual or semi-automated assembly. Select packaging based on production volume and assembly equipment specifications.

Q: Is the M30U474M5-F still available for purchase?

A: The M30U474M5-F is classified as obsolete. While legacy inventory may exist, active product substitutes from KEMET and KYOCERA AVX are recommended for new designs and ongoing procurement to ensure long-term supply continuity and support.
