| FFF Compatibility | Both components share the standard 0603 (1608 Metric) surface mount footprint with two terminals and identical land pattern requirements.The physical dimensions, package height, and mounting style are identical to the original component.The electrical specifications, including the 24V standoff voltage, 150V typical clamping voltage, and ultra-low capacitance, are identical to the original. | Utilizes the identical 2 term-terminal 0603 (1608 Metric) surface mount package with matching land pattern.The overall physical envelope and mounting configuration are identical to the original device.The clamping voltage is significantly lower (45V vs 150V), which is an improvement, but capacitance is slightly higher (0.25pF typ vs 0.055pF typ) which could affect extremely high-speed signal lines. | ||
 AI Summary | PGB0010603 by Littelfuse: 150V (Typ) Clamp Ipp Tvs Diode Surface Mount 0603 (1608 Metric). | This is the official, direct manufacturer-recommended replacement designed to succeed the obsolete PGB0010603. It transitions the product line to full RoHS3 compliance while maintaining identical physical dimensions and electrical performance.
| This is an alternative polymer ESD suppressor from Littelfuse. While it offers a significantly improved (lower) clamping voltage of 45V for better circuit protection, its slightly higher capacitance of 0.25pF makes it a partial functional match if used in ultra-high-speed RF or microwave lines.

Frequently asked questions
Yes. The Littelfuse PGB0010603 is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Littelfuse PGB0010603 are the PGB1010603MR (Littelfuse Inc.) and the PESD0603-240 (Littelfuse Inc.), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the PGB0010603 are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The PGB0010603 (Littelfuse) is a part in the Transient Voltage Suppressors (TVS) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
