Engineering Selection Recommendations

Primary Substitutes (Active Status, Recommended for New Designs):

The 3M 8225-6000, 8225-6003, 8225-6009, and 8225-8000 connectors are active products suitable for applications requiring panel mount configurations. These parts maintain the 25 position D-Sub plug format with IDC ribbon cable termination and UL94 V-0 flammability rating. The 3M 8225 series parts are ROHS3 compliant. Current rating on these parts is 1A, which is lower than the L117DBFRAA25P specification of 5A. Selection of these parts requires confirmation that application current requirements do not exceed 1A.

The Assmann WSW Components A-DSF 25 LPIII/Z-UNC is an active product with free hanging in-line mounting matching the L117DBFRAA25P mounting type. This part provides 3A current rating and 250V voltage rating. Operating temperature range is -55°C to 105°C, which is narrower than the L117DBFRAA25P range of -40°C to 125°C. This part is ROHS3 compliant and REACH unaffected.

Secondary Substitutes (Obsolete Status, Not Recommended for New Designs):

The 3M 8225-7000 and 8225-7003 connectors are obsolete products. These parts are panel mount configurations with 1A current rating. Obsolete status indicates these parts are no longer in active production. Use of obsolete parts is not recommended for new designs or long-term applications.

Selection Criteria:

For applications requiring free hanging in-line mounting with current ratings of 3A or higher, the Assmann WSW Components A-DSF 25 LPIII/Z-UNC is the primary active substitute.
For applications requiring panel mount configurations with lower current requirements (1A maximum), the 3M 8225 series active products (8225-6000, 8225-6003, 8225-6009, 8225-8000) are suitable.
Obsolete parts (8225-7000, 8225-7003) should not be selected for new applications.
All listed substitutes maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.
All listed substitutes are RoHS compliant (either RoHS or ROHS3).

Frequently Asked Questions (FAQ)

Q: Can the 3M 8225 series parts directly replace the L117DBFRAA25P in existing applications?

A: The 3M 8225 series parts share the same 25 position D-Sub plug configuration, IDC ribbon cable termination, and shell size. However, they differ in mounting type (panel mount vs. free hanging in-line) and current rating (1A vs. 5A). Direct replacement is possible only if the application uses panel mount configuration and current requirements do not exceed 1A.

Q: What is the difference between the 3M 8225-6000, 8225-6003, 8225-6009, and 8225-8000?

A: All four parts are 25 position D-Sub plugs with panel mount configuration and 1A current rating. The primary differences are flange feature specifications (unthreaded vs. 4-40 threaded) and packaging (tray vs. bulk). The 8225-6000 and 8225-6009 have unthreaded flanges, while 8225-6003 has 4-40 threaded flange. The 8225-6000 and 8225-6003 are packaged in trays, while 8225-6009 and 8225-8000 are packaged in bulk.

Q: Why do the 3M 8225 series parts have a lower current rating (1A) compared to the L117DBFRAA25P (5A)?

A: Current rating is determined by contact material, contact finish, and connector design specifications. The 3M 8225 series uses copper alloy contacts with tin plating, while the L117DBFRAA25P uses brass contacts with nickel plating. These material and finish differences result in different current handling capabilities.

Q: Is the Assmann WSW Components A-DSF 25 LPIII/Z-UNC a suitable substitute for the L117DBFRAA25P?

A: The Assmann part matches the L117DBFRAA25P in mounting type (free hanging in-line), connector style (D-Sub 25 position plug), and termination method (IDC ribbon cable). The Assmann part provides 3A current rating and 250V voltage rating. The operating temperature range is -55°C to 105°C, which does not cover the upper temperature limit of the L117DBFRAA25P (-40°C to 125°C). Selection of the Assmann part requires confirmation that application operating temperatures do not exceed 105°C.

Q: What does "obsolete" product status mean for the 3M 8225-7000 and 8225-7003?

A: Obsolete status indicates that these parts are no longer in active production by the manufacturer. While inventory may still be available, obsolete parts are not recommended for new designs or applications requiring long-term component availability. Future availability and support cannot be guaranteed for obsolete parts.

Q: Are all substitute parts RoHS compliant?

A: Yes, all listed substitute parts are RoHS compliant. The L117DBFRAA25P and Assmann A-DSF 25 LPIII/Z-UNC are RoHS compliant. The 3M 8225 series parts are ROHS3 compliant, which is a more recent RoHS directive revision. All parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the difference between tray and bulk packaging?

A: Packaging type affects handling and storage but does not impact electrical or mechanical connector specifications. Tray packaging provides organized component storage with individual compartments, while bulk packaging contains loose components. Selection between tray and bulk packaging depends on inventory management and assembly process requirements.

Q: Can I use a panel mount connector in place of a free hanging in-line connector?

A: No. Mounting type is a critical mechanical parameter that determines how the connector is installed in the application. Free hanging in-line connectors are designed for cable-to-cable connections without panel mounting hardware. Panel mount connectors require mounting holes and hardware for installation on a panel or enclosure. These are not interchangeable without mechanical redesign of the application.
