Each part maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications.

Selection between these parts should be based on availability, lead time, and inventory status. The Panasonic EEU-FS2A271S offers 702 units in stock. The Rubycon 100ZLH270MEFC16X20 provides 1,239 units, and the Rubycon 100ZLJ270M16X20 offers 1,684 units in current inventory. All parts are active products with confirmed production status.

Frequently Asked Questions (FAQ)

Q: Can 100ZLH270MEFC16X20 and 100ZLJ270M16X20 be used interchangeably with EEU-FS2A271S?

A: Yes. All three parts share identical capacitance (270 µF), voltage rating (100 V), tolerance (±20%), lifetime rating (10,000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), physical dimensions, lead spacing, and mounting configuration. They are functionally equivalent for general-purpose applications.

Q: What are the differences between the substitute parts?

A: The primary differences are manufacturer (Panasonic vs. Rubycon) and series designation (FS-A vs. ZLH vs. ZLJ). Ripple current ratings and impedance values vary slightly: the Panasonic part has 32 mOhms impedance, while the Rubycon ZLH has 58 mOhms and the ZLJ has 48 mOhms. These variations do not affect functional equivalence for applications within the specified electrical parameters.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts have identical lead spacing (0.295" / 7.50 mm), diameter (0.630" / 16.00 mm), and maximum seated height (0.866" / 22.00 mm). They are direct mechanical replacements in through-hole PCB applications.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and commercial electronics manufacturing.

Q: Which part should I select based on availability?

A: Selection should prioritize current inventory levels and procurement lead times. The Rubycon 100ZLJ270M16X20 has the highest inventory (1,684 units), followed by 100ZLH270MEFC16X20 (1,239 units), and EEU-FS2A271S (702 units).
