Engineering Selection Recommendations

Both the 337SAK100M and EGXF101ELL331MM20S are Active products with full RoHS compliance and MSL 1 rating, confirming suitability for current manufacturing and assembly processes.

The EGXF101ELL331MM20S from Chemi-Con carries AEC-Q200 automotive qualification, indicating enhanced reliability screening and extended operational temperature range (-40°C to 125°C versus -40°C to 85°C). This upgrade path is applicable when designs require automotive-grade components or extended thermal performance margins.

Both parts are electrically and mechanically interchangeable. Selection between them depends on application requirements: the 337SAK100M for standard general-purpose use, or the EGXF101ELL331MM20S when automotive qualification or extended temperature operation is specified.

Frequently Asked Questions (FAQ)

Q: Can the EGXF101ELL331MM20S replace the 337SAK100M in existing designs?

A: Yes. Both parts share identical electrical specifications (330 µF, ±20%, 100 V), polarization (Polar), and mechanical dimensions (0.709" Dia, 0.846" Height, 0.295" lead spacing). Through-hole mounting and radial can packaging are identical. Direct substitution is supported without PCB layout modification.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Cornell Dubilier versus Chemi-Con) and performance ratings. The EGXF101ELL331MM20S features lower ESR (69 mOhm @ 100 kHz versus 402 mOhm @ 120 Hz), extended lifetime (3000 Hrs @ 125°C versus 2000 Hrs @ 85°C), higher operating temperature ceiling (125°C versus 85°C), and AEC-Q200 automotive qualification. Electrical capacitance and voltage ratings remain identical.

Q: Are both parts RoHS compliant?

A: Yes. The 337SAK100M is ROHS3 Compliant. The EGXF101ELL331MM20S is RoHS Compliant. Both meet current environmental and regulatory requirements for manufacturing and assembly.

Q: What is the MSL rating for these capacitors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special desiccant or humidity control requirements.

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

A: Yes. Identical lead spacing (0.295" / 7.50 mm), can diameter (0.709" / 18.00 mm), and seated height (0.846" / 21.50 mm) ensure mechanical compatibility with existing through-hole footprints. No PCB redesign is required.

Q: Which part should be selected for automotive applications?

A: The EGXF101ELL331MM20S is qualified to AEC-Q200 automotive standards and operates to 125°C, making it the appropriate choice for automotive or extended-temperature environments. The 337SAK100M is suitable for general-purpose applications within standard temperature ranges.
