Key Parameters

Substitute Part Grouping Explanation

Substitution of the DBMS25SN is based on strict electrical and mechanical parameter matching within the D-Sub connector category. The substitute part DBMS25S maintains compatibility through the following critical parameters:

Connector configuration: 25 positions, 2 rows, Shell Size 3 (DB, B) Termination method: Solder Cup Contact specifications: Female sockets, brass material, gold finish Electrical ratings: 7.5A per contact, 300V Thermal range: -55°C to 155°C Shell construction: Steel with yellow cadmium plating Dielectric material: Thermoplastic Flammability compliance: UL94 V-0

The DBMS25S differs only in product status (Active versus Obsolete) and packaging format (Tray versus unspecified), with no changes to functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The DBMS25S is the direct substitute for the obsolete DBMS25SN. Both parts are manufactured by Amphenol ICC (FCI) and share identical electrical, mechanical, and thermal specifications. The DBMS25S maintains active product status, ensuring continued availability and supply chain reliability. Both parts comply with UL94 V-0 flammability requirements and are suitable for applications requiring 25-position D-Sub receptacle connectors with solder cup termination in the specified temperature and voltage ranges. Selection of the DBMS25S eliminates obsolescence risk while preserving full functional compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can DBMS25S directly replace DBMS25SN in existing designs? A: Yes. The DBMS25S is electrically and mechanically identical to the DBMS25SN. All functional parameters, including position count, contact ratings, termination method, and operating specifications, are equivalent.

Q: What is the primary reason for substitution? A: The DBMS25SN is classified as obsolete. The DBMS25S is the active equivalent part, ensuring continued procurement availability and supply chain support.

Q: Are there differences in packaging between these parts? A: The DBMS25SN packaging is unspecified, while the DBMS25S is supplied in Tray packaging. This difference does not affect connector functionality or performance.

Q: Do both parts meet the same compliance standards? A: Yes. Both parts comply with UL94 V-0 flammability rating and are rated for identical electrical parameters: 7.5A per contact at 300V.

Q: What is the operating temperature range for these connectors? A: Both parts operate across -55°C to 155°C, suitable for industrial and extended temperature applications.

Q: Are the contact materials and finishes identical? A: Yes. Both parts feature brass contacts with gold finish, ensuring equivalent electrical performance and corrosion resistance.
