Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Highest Compatibility):

The TE Connectivity 5747845-3 is the direct equivalent to the 747845-3. Both parts share identical electrical and mechanical specifications, including 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range. The primary difference is RoHS compliance status; the 5747845-3 is RoHS Compliant, whereas the 747845-3 is not applicable. This part is suitable for direct substitution in all applications where the 747845-3 is specified.

Compatible Substitutes with Parameter Deviations:

The Amphenol ICC (FCI) Delta D series connectors (D15S33E4GV00LF, D15S33E4GX00LF, D15S33E6GX00LF) provide enhanced electrical performance with 5A per contact current rating, 300V voltage rating, and extended operating temperature to 125°C. These parts are RoHS Compliant and suitable for applications requiring higher voltage or temperature margins. The tin-nickel plated steel shell provides improved corrosion resistance compared to tin-plated alternatives.

The Assmann WSW Components A-DF 15 series (A-DF 15 A/KG-T2S and A-DF 15 A/KG-T4S) are ROHS3 Compliant alternatives with 3A current rating and 250V voltage rating. These parts maintain the -55°C to 105°C operating temperature range and are suitable for applications with reduced current requirements. The glass-filled PBT dielectric material provides enhanced mechanical stability.

The NorComp 182-015-213R531 offers ROHS3 compliance with 5A current rating and -55°C to 105°C operating temperature range. This part supports panel mount configuration in addition to through-hole mounting, providing design flexibility for applications requiring front-panel accessibility.

The Mercury United Electronics 622 series connectors (622-015-260-042, 622-015-260-011, 622-015-260-013) are ROHS3 Compliant alternatives with 3A per contact current rating. These parts feature nickel-plated steel shells and support board edge mounting in addition to through-hole configuration. Operating temperature is limited to -55°C to 85°C, making these parts suitable for standard industrial temperature ranges but not for extended high-temperature applications.

Selection Criteria by Application:

For applications requiring RoHS compliance with identical electrical specifications, select 5747845-3. For applications requiring higher voltage or temperature performance, select Amphenol ICC (FCI) Delta D series parts. For applications with reduced current requirements and RoHS compliance, select Assmann WSW or Mercury United Electronics alternatives. For applications requiring panel mount capability, select NorComp 182-015-213R531.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5747845-3 be used as a direct replacement for the 747845-3?

A: Yes. The 5747845-3 is electrically and mechanically identical to the 747845-3, with the same 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range. The primary difference is RoHS compliance status. Both parts are suitable for identical applications.

Q: What is the difference between the Amphenol ICC (FCI) D15S33E4GX00LF and D15S33E6GX00LF?

A: Both parts share identical electrical and mechanical specifications, including 5A per contact current rating, 300V voltage rating, and -55°C to 125°C operating temperature range. The D15S33E6GX00LF features enhanced contact finish with 30.0µin (0.76µm) gold or gold GXT™ plating, compared to flash plating on the D15S33E4GX00LF. Both are RoHS Compliant.

Q: Can I use a 3A-rated connector in place of the 6A-rated 747845-3?

A: A 3A-rated connector is suitable only for applications where the actual current draw does not exceed 3A per contact. The 747845-3 is rated for 6A, so substitution with lower-rated parts requires verification that application current requirements do not exceed the substitute part's rating.

Q: What is the difference between housing/shell flange and mating side screwlock configurations?

A: Housing/shell (4-40) flange features threaded mounting holes on the connector housing for panel or PCB mounting. Mating side female screwlock (4-40) features threaded holes on the mating connector interface for secure mating. Both configurations support the same 4-40 thread specification but differ in mounting location and application.

Q: Are all substitute parts suitable for the same operating temperature range as the 747845-3?

A: No. The 747845-3 operates from -55°C to 105°C. Mercury United Electronics 622 series parts operate from -55°C to 85°C, which is suitable for standard industrial applications but not for extended high-temperature environments. Amphenol ICC (FCI) Delta D series parts extend to 125°C, providing additional temperature margin. Verify application temperature requirements before substitution.

Q: What is the significance of RoHS compliance in connector selection?

A: RoHS compliance indicates the connector meets Restriction of Hazardous Substances regulations, restricting lead, cadmium, mercury, and other hazardous materials. The 747845-3 is marked "Not applicable" for RoHS status. The 5747845-3 is RoHS Compliant, and most alternative manufacturers (Assmann, Mercury, NorComp) offer ROHS3 Compliant versions. RoHS compliance is required for products sold in the European Union and increasingly required by OEMs globally.

Q: Can I use a nickel-plated shell connector instead of tin-plated?

A: Yes. Both tin-plated and nickel-plated steel shells are acceptable for D-Sub connectors. Nickel plating provides enhanced corrosion resistance in harsh environments, while tin plating is suitable for standard industrial applications. The choice depends on environmental exposure and application requirements.

Q: What does "backset spacing 0.318" (8.08mm)" mean?

A: Backset spacing refers to the distance from the rear of the connector shell to the solder cup termination points. This dimension is critical for PCB layout and component placement. The 0.318" (8.08mm) specification is standard for 15-position D-Sub connectors and is consistent across all substitute parts listed, with minor tolerance variations (0.319" for Assmann parts).

Q: Are there packaging differences between substitute parts?

A: Yes. The 747845-3 and most substitute parts are supplied in trays. Mercury United Electronics 622-015-260-011 and 622-015-260-013 are supplied in bulk packaging. Tray packaging provides better component protection and organization for automated assembly, while bulk packaging is suitable for manual assembly or reel-based processes.

Q: What is the difference between phosphor bronze and copper alloy contact materials?

A: Both phosphor bronze and copper alloy are acceptable contact materials for D-Sub connectors. Phosphor bronze provides superior spring properties and wear resistance, making it suitable for high-cycle mating applications. Copper alloy offers good electrical conductivity and cost efficiency. The 747845-3 uses phosphor bronze; substitute parts use either phosphor bronze or copper alloy, both acceptable for standard signal applications.
