Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DBKL-25SAT-F are qualified based on the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 25
• Number of rows: 2
• Shell size and layout: 3 (DB, B)
• Mounting type: Right Angle, Through Hole
• Termination method: Solder
• Flange feature: Mating Side, Female Screwlock (4-40)
• Contact finish: Gold
• Material flammability: UL94 V-0
• RoHS compliance: ROHS3 Compliant

Acceptable Variations:

• Shell material finish: Steel with Nickel or Tin plating
• Current rating: Equal to or greater than 3A per contact
• Operating temperature: Equal to or greater than -55°C to 85°C
• Contact material: Copper Alloy or Phosphor Bronze

The substitute parts 622-025-260-043 (Mercury United Electronics) and 5747846-6 (TE Connectivity) meet all mandatory matching parameters and are therefore direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three parts—DBKL-25SAT-F, 622-025-260-043, and 5747846-6—are active production components with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts should be based on the following factors:

DBKL-25SAT-F (Cinch Connectivity Solutions): Primary choice when Cinch series continuity is required or when the original design specification calls for this manufacturer.

622-025-260-043 (Mercury United Electronics): Suitable for applications requiring Mercury series components. Provides 3A per contact current rating and operates within -55°C to 85°C range. Nickel-plated steel shell with flash gold contact finish.

5747846-6 (TE Connectivity AMPLIMITE HD-20): Suitable for applications requiring TE Connectivity components. Provides higher current rating of 6A and extended operating temperature range to 105°C. Includes 125V voltage rating specification. Tin-plated steel shell with 30.0µin gold contact finish thickness.

All parts feature identical mechanical compatibility, mounting configuration, and electrical interface characteristics. Selection may be driven by supply chain requirements, cost considerations, or existing design standardization on a specific manufacturer platform.

Frequently Asked Questions (FAQ)

Q: Can 622-025-260-043 be used as a direct replacement for DBKL-25SAT-F?

A: Yes. Both connectors share identical mechanical and electrical specifications including 25 positions, 2-row configuration, right-angle solder termination, and female screwlock flange. Both are ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What is the difference between the tin-plated and nickel-plated shell finishes?

A: The DBKL-25SAT-F and 622-025-260-043 feature nickel-plated steel shells, while the 5747846-6 features tin-plated steel. Both finishes provide corrosion resistance and are suitable for standard environmental conditions. Finish selection may depend on specific application requirements or existing design standards.

Q: Does the higher current rating of 5747846-6 (6A vs 3A) affect compatibility?

A: No. The 5747846-6 current rating of 6A per contact exceeds the 3A specification of 622-025-260-043. Higher current rating capability does not affect mechanical or electrical interface compatibility. The connector can be used in applications requiring either 3A or 6A per contact operation.

Q: Are all three parts suitable for the same operating temperature range?

A: The DBKL-25SAT-F and 622-025-260-043 operate from -55°C to 85°C. The 5747846-6 extends this range to -55°C to 105°C. For applications requiring operation above 85°C, the 5747846-6 is the appropriate selection.

Q: What packaging is available for these parts?

A: The 622-025-260-043 and 5747846-6 are supplied in Tray packaging. Packaging information for DBKL-25SAT-F is not specified in the provided data.

Q: Are all parts RoHS compliant?

A: Yes. All three parts—DBKL-25SAT-F, 622-025-260-043, and 5747846-6—are ROHS3 compliant and suitable for applications requiring RoHS compliance.
