Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across electrical and mechanical parameters. All substitute parts listed maintain identical capacitance (0.1 µF), voltage rating (50V), tolerance (±20%), temperature coefficient (Z5U), and operating temperature range (10°C ~ 85°C). All substitutes feature through-hole radial configuration with 0.200" (5.08mm) lead spacing, ensuring direct PCB footprint compatibility with the original M22U104M5-F.

Substitutes are grouped by manufacturer and packaging format. Physical dimensions vary within acceptable ranges for radial ceramic capacitors, with height and body width differences reflecting different design generations and manufacturing standards. These dimensional variations do not affect electrical performance or circuit functionality when lead spacing and mounting type remain constant.

All substitute parts maintain ROHS3 compliance and MSL Level 1 or Not Applicable ratings, confirming regulatory and handling compatibility with the original specification.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the M22U104M5-F. Selection among active alternatives should prioritize parts with Active product status, ensuring long-term availability and manufacturing support. KEMET GoldMax 300 Comm Z5U series (C317C and C322C variants) and KYOCERA AVX SkyCap SR series (SR125E and SR215E variants) all maintain full ROHS3 compliance and appropriate MSL ratings.

For new production designs, KEMET C322C104M5U5TA or C322C104M5U5TA7301 offer the highest inventory levels (66,026 and 10,672 units respectively), supporting supply chain continuity. KYOCERA AVX SR215E104MAA provides 10,781 units in bulk packaging, offering alternative sourcing from a second manufacturer.

Packaging format selection depends on assembly requirements: Bulk packaging suits high-volume production runs, while Cut Tape (CT) packaging accommodates automated pick-and-place equipment. All variants maintain identical electrical performance and PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can C317C104M5U5TA replace M22U104M5-F directly on existing PCBs?

A: Yes. Both parts share identical capacitance (0.1 µF), voltage rating (50V), tolerance (±20%), temperature coefficient (Z5U), and lead spacing (0.200"). Physical dimensions differ slightly, but the radial through-hole configuration and lead spacing ensure direct PCB footprint compatibility without layout modifications.

Q: What is the difference between C317C104M5U5TA and C322C104M5U5TA?

A: Both are KEMET GoldMax 300 Comm Z5U series parts with identical electrical specifications. The primary difference is physical size: C317C measures 0.150" L x 0.100" W with 0.200" height, while C322C measures 0.200" L x 0.125" W with 0.260" height. Selection depends on available PCB space and lead spacing requirements, which remain constant at 0.200" for both.

Q: Are KYOCERA AVX SR125E and SR215E variants interchangeable?

A: Electrically, yes. Both maintain 0.1 µF capacitance, 50V rating, Z5U temperature coefficient, and 0.200" lead spacing. Physical dimensions differ: SR125E measures 0.150" L x 0.150" W with 0.100" height, while SR215E measures 0.200" L x 0.125" W with 0.200" height. PCB layout space availability determines which variant is appropriate.

Q: What does the "7301" suffix in KEMET part numbers indicate?

A: The 7301 suffix identifies Cut Tape (CT) packaging format, suitable for automated assembly equipment. Parts without this suffix are supplied in Bulk packaging. Electrical specifications remain identical; packaging format only affects handling and assembly methodology.

Q: Do all substitutes maintain ROHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the original M22U104M5-F specification. This ensures regulatory compatibility for applications requiring lead-free component certification.

Q: What is the significance of MSL Level 1 rating?

A: MSL Level 1 indicates unlimited shelf life without moisture bake-out requirements. The original M22U104M5-F carries MSL Level 1. KEMET substitutes list MSL as Not Applicable, and KYOCERA AVX substitutes also list Not Applicable, indicating these parts do not require moisture sensitivity management during storage and handling.

Q: Can I use SR215E104MAATR1 in place of SR215E104MAA?

A: Yes, electrically and mechanically. The MAATR1 variant uses Cut Tape (CT) packaging with kinked formed leads, while MAA uses Bulk packaging with kinked formed leads. Both maintain identical electrical specifications and 0.200" lead spacing. The primary difference is packaging format and lead forming style for automated assembly compatibility.
