Key Parameters

Substitute Part Grouping Explanation

The substitute part 5-747913-2 (TE Connectivity AMP Connectors) qualifies as an equivalent option based on the following critical parameters that define functional interchangeability:

Matching Parameters:

• Connector style: D-Sub receptacle with female sockets
• Position count: 25 positions
• Shell size and layout: 3 (DB, B)
• Contact type: Signal
• Termination method: Solder cup
• Flange feature: Housing/Shell (Unthreaded)
• Contact finish: Gold
• Material flammability rating: UL94 V-0
• Operating temperature range: -55°C minimum (both parts)
• RoHS compliance: Both parts meet regulatory requirements
• ECCN classification: EAR99 (both parts)

Differing Parameters:

• Mounting type: DBMF25S is panel mount; 5-747913-2 is free hanging (in-line)
• Current rating: DBMF25S rated 7.5A; 5-747913-2 rated 3A
• Operating temperature maximum: DBMF25S to 125°C; 5-747913-2 to 105°C
• Shell material finish: DBMF25S uses yellow chromate plated zinc; 5-747913-2 uses tin plated
• Dielectric material: DBMF25S uses PCT; 5-747913-2 uses PBT glass filled
• Contact material: DBMF25S uses copper alloy; 5-747913-2 uses brass
• Voltage rating: 5-747913-2 specifies 250V; DBMF25S does not specify

Parameter Comparison

Engineering Selection Recommendations

Both the DBMF25S and 5-747913-2 maintain active product status and meet RoHS compliance requirements, establishing baseline regulatory compatibility. The DBMF25S is optimized for panel mount applications with higher current capacity (7.5A) and extended temperature operation to 125°C. The 5-747913-2 serves free hanging in-line configurations with a specified 250V voltage rating and operates to 105°C maximum.

Selection between these parts depends on application-specific requirements. Panel mount installations require the DBMF25S. Applications requiring in-line free hanging configuration necessitate the 5-747913-2. Current requirements exceeding 3A mandate the DBMF25S. Operating environments above 105°C require the DBMF25S. Both parts satisfy signal-level applications with solder cup termination and 25 position D-Sub connectivity.

Frequently Asked Questions (FAQ)

Q: Can 5-747913-2 replace DBMF25S in a panel mount application? A: No. The 5-747913-2 is configured for free hanging in-line mounting, while DBMF25S is designed for panel mount installation. Mechanical compatibility requires matching mounting type.

Q: What is the impact of the current rating difference between these parts? A: DBMF25S is rated for 7.5A while 5-747913-2 is rated for 3A. Applications requiring current above 3A must use DBMF25S. Applications operating at or below 3A may use either part.

Q: Are the dielectric materials interchangeable? A: Both materials (PCT and PBT glass filled) meet UL94 V-0 flammability requirements. Material selection depends on specific environmental and mechanical stress conditions in the application. Consult application requirements before substitution.

Q: What is the significance of the operating temperature range difference? A: DBMF25S operates from -55°C to 125°C while 5-747913-2 operates from -55°C to 105°C. Applications requiring operation above 105°C require DBMF25S.

Q: Do both parts support the same wire gauge? A: DBMF25S specifies 20-28 AWG wire gauge. 5-747913-2 does not specify wire gauge in the provided data. Consult manufacturer documentation for 5-747913-2 wire gauge specifications before termination.

Q: Are both parts RoHS compliant? A: Yes. DBMF25S is RoHS Compliant and 5-747913-2 is ROHS3 Compliant. Both meet current regulatory requirements.

Q: What is the difference in shell material finish? A: DBMF25S uses yellow chromate plated zinc finish while 5-747913-2 uses tin plated finish. Both provide corrosion protection suitable for industrial applications. Environmental exposure conditions may influence finish selection.
