Three Legacy Part Numbers Replaced by the 03-235-SPA

The 03-235-SPA replaces three legacy part numbers, as confirmed on the SecurityParts.com product page under "Original Part#."

• 23854540: Original part number for cylindrical lock outside trim positions using the Sparta Corbin Russwin FSIC J-CO7 lever.
• 09-366-SPA: Original part number for mortise lock trim applications. The 09 prefix in the legacy Schlage system identified mortise trim levers.
• 03-366-SPA: Original part number for exit device outside trim applications.

All three installation types are served by the 03-235-SPA as the current OEM part number. Any maintenance record or specification referencing these three legacy numbers maps to the 03-235-SPA for current ordering.

03-235-SPA vs 03-235-RHO: NDE Coverage Distinction

The 03-235-SPA and the 03-235-RHO (Rhodes Lever, Corbin Russwin FSIC J-CO7) are both standard non-tactile levers in the 03-235 Corbin Russwin J-CO7 FSIC format. Both ship less core, are In Stock at the same price, and cover AD, CO, ALX, and ND Series. Two key differences distinguish them.

First, the lever profile. The 03-235-SPA uses the Sparta design and the 03-235-RHO uses the Rhodes design. Second, the NDE Series coverage. The 03-235-RHO is documented in five Service Manuals including the NDE Series. The 03-235-SPA is documented in four Service Manuals and does not include the NDE Series. When the installed lock is an NDE exit device configured for Corbin Russwin J-CO7 FSIC cores and the Sparta profile is required, confirm the correct current specification before ordering the 03-235-SPA. When NDE Series coverage is not a factor and the Sparta profile is the building standard, the 03-235-SPA is the correct part.

FSIC/LFIC Product Type and J-CO7 Keyway Specification

The 03-235-SPA product type is confirmed as "Full Size Interchangeable Core (FSIC / LFIC) Lever Trim (Less Core)" on the SecurityParts.com product page. This FSIC/LFIC designation also appears on the tactile 03-235-8SP and 03-235-8TR levers in the same format family. The 03-235-RHO uses only FSIC in its product type designation. The J-CO7 keyway specifically identifies the Corbin Russwin core profile this lever accepts, per the product page FAQ.
