Engineering Selection Recommendations
Direct Equivalent (Highest Compatibility):
The part number 1-5747150-3 from TE Connectivity AMP Connectors is a direct equivalent to 1-747150-3. Both parts share identical electrical and mechanical specifications within the AMPLIMITE HD-20 series. The primary difference is RoHS3 compliance status on the substitute part. This part is suitable for direct replacement in all applications.
Primary Substitutes (Full Compatibility):
The Amphenol ICC (FCI) Delta D series parts D09S24A4GX00LF, D09S24A4GV00LF, D09S24A4GL00LF, and D09S24A4PA00LF are functionally equivalent receptacles. These parts meet or exceed all critical electrical parameters. Voltage rating is elevated to 300V, and operating temperature range extends to 125°C. Current rating is 5A per contact, which is within acceptable range for signal applications. All parts carry RoHS compliance certification. These substitutes are suitable for applications where the original part is unavailable.
Secondary Substitutes (Conditional Compatibility):
The HARTING 09641127230 is a 9-position D-Sub receptacle with through-hole solder termination. This part features a higher current rating of 7.5A and operates across -20°C to 125°C. The voltage rating of 100V is lower than the original specification. This part is suitable for applications where lower voltage operation is acceptable and higher current capacity is beneficial.
The Assmann WSW Components A-DF 09 PP/Z is a 9-position D-Sub receptacle with through-hole solder termination. Current rating is 3A, which is lower than the original 6A specification. Voltage rating is 250V. This part is suitable only for applications with reduced current requirements.
Not Recommended for Direct Substitution:
The NorComp Inc. parts 172-009-212R021 and 191-009-213L571 feature panel-mount configurations in addition to through-hole mounting. The 172-009-212R021 is classified as Obsolete product status and has a reduced operating temperature maximum of 100°C. The 191-009-213L571 includes shielding and board-lock features not present in the original part. These parts are suitable only when panel-mount capability is specifically required.
The Amphenol ICC (FCI) D09P24A4PX00LF is a plug connector with male pins, not a receptacle with female sockets, and is not a substitute for this receptacle application.
Frequently Asked Questions (FAQ)
Q: Can I use part 1-5747150-3 as a direct replacement for 1-747150-3?
A: Yes. Both parts are from TE Connectivity AMP Connectors within the AMPLIMITE HD-20 series and share identical electrical and mechanical specifications. The substitute part carries ROHS3 compliance certification, which may be required in certain applications.
Q: What is the difference between the TE Connectivity and Amphenol ICC substitutes?
A: The TE Connectivity 1-5747150-3 is a direct equivalent with identical specifications. The Amphenol ICC Delta D series parts (D09S24A4GX00LF, D09S24A4GV00LF, D09S24A4GL00LF, D09S24A4PA00LF) are functionally equivalent but feature higher voltage rating (300V vs. 125V), extended operating temperature range (-55°C to 125°C vs. -55°C to 105°C), and slightly lower current rating per contact (5A vs. 6A). All are suitable substitutes for the original part.
Q: Can I use the Assmann WSW Components A-DF 09 PP/Z in place of the original part?
A: The Assmann part is a 9-position D-Sub receptacle with compatible form factor and solder termination. However, the current rating is 3A, which is half the original 6A specification. This part is suitable only for applications with reduced current requirements.
Q: What does "through-hole" mounting mean, and why is it important?
A: Through-hole mounting indicates that the connector's solder pins pass through holes in the printed circuit board and are soldered on the opposite side. This is the standard mounting method for the original part and all recommended substitutes. Panel-mount variants (such as NorComp parts) have additional flange features for mounting to enclosure panels and are not direct substitutes unless panel mounting is required.
Q: Are all substitute parts RoHS compliant?
A: The TE Connectivity 1-5747150-3 and all Amphenol ICC Delta D series parts carry RoHS compliance certification (either RoHS or ROHS3). The HARTING 09641127230 and Assmann WSW Components A-DF 09 PP/Z are ROHS3 compliant. The NorComp parts are ROHS3 compliant. The original 1-747150-3 is marked as "Not applicable" for RoHS status. Verify RoHS requirements for your specific application before selecting a substitute.
Q: What is the difference between "Tin Plated" and "Tin-Nickel Plated" shell finishes?
A: Both finishes provide corrosion resistance for the steel shell. Tin plating is a single-layer finish, while tin-nickel plating is a multi-layer finish that provides enhanced corrosion resistance and durability. Tin-nickel plated parts (Amphenol ICC substitutes) are suitable for more demanding environmental conditions. Both finishes are compatible with the original application.
Q: Can I use a part with a lower current rating than the original?
A: The original part is rated for 6A. Substitutes with lower current ratings (such as the Assmann part at 3A) can be used only if your application's actual current draw does not exceed the substitute part's rating. Exceeding the current rating may result in connector failure or safety hazards.
Q: Why are some parts listed as "Obsolete"?
A: The NorComp 172-009-212R021 is classified as Obsolete, meaning it is no longer manufactured or supported by the vendor. While it may still be available from inventory, it is not recommended for new designs or long-term supply chain planning. Active parts are preferred for ongoing applications.
Q: What is the significance of the "Flange Feature" parameter?
A: The flange feature describes how the connector is secured. The original part has a "Mating Side, Female Screwlock (4-40)" flange, meaning the mating connector screws into the receptacle. Substitutes may have different flange configurations such as "Housing/Shell (4-40)" or "Housing/Shell (Unthreaded)". These variations affect how the connector is mounted and mated but do not prevent electrical compatibility if the connector type and position count match.
Q: Is packaging format (Tube, Tray, Bulk) important for substitution?
A: Packaging format affects order quantity and handling but does not affect electrical or mechanical compatibility. The original part is supplied in Tube packaging. Substitutes may be supplied in Tray or Bulk packaging. Verify packaging availability with your supplier to ensure it meets your procurement requirements.
