Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 745183-3 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Number of rows: 2
• Shell size and layout: 1 (DE, E)
• Termination method: Solder
• Material flammability rating: UL94 V-0

Allowable Variations:

• Mounting type: Through hole variants with panel mount capability are acceptable
• Shell material finish: Steel with tin or nickel plating
• Dielectric material: Thermoplastic, polyamide, or polybutylene terephthalate
• Contact material: Phosphor bronze or brass
• Flange feature configuration: Housing/shell unthreaded, board side, or mating side variations
• Current rating: Minimum 3A per contact (main part rated 6A)
• Operating temperature range: Minimum -50°C to 85°C (main part -55°C to 105°C)
• RoHS compliance status: Both compliant and non-compliant parts listed

The substitute parts listed maintain D-Sub 9-position receptacle functionality with solder termination and UL94 V-0 flammability rating across all variants.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Highest Compatibility):

The TE Connectivity 5745183-3 is the direct equivalent to the 745183-3. Both parts share identical electrical ratings (6A, 125V), operating temperature range (-55°C to 105°C), connector configuration (9-position D-Sub receptacle), and mounting method (through-hole solder). The primary difference is RoHS3 compliance status: 5745183-3 is ROHS3 compliant while 745183-3 is non-compliant. Selection of 5745183-3 is appropriate when RoHS3 compliance is required or when the original part becomes unavailable.

Alternative Substitutes (Conditional Compatibility):

The NorComp 172-009 series (172-009-283L001, 172-009-283L011, 172-009-283L021, 172-009-283L031) provides D-Sub 9-position receptacle functionality with solder termination and UL94 V-0 rating. These parts differ in current rating (5A versus 6A), mounting configuration (panel mount capability), shell finish (nickel versus tin plating), contact material (brass versus phosphor bronze), and dielectric material (PBT versus thermoplastic). These parts are ROHS3 compliant and suitable for applications where the reduced current rating and alternative mounting options are acceptable.

The Mercury United Electronics 628-009-321-056 is a shielded D-Sub 9-position receptacle with board lock features and ROHS3 compliance. This part has a reduced current rating (3A per contact) and narrower operating temperature range (-55°C to 85°C) compared to the main part. Selection is appropriate for applications requiring shielding and board lock functionality where current and temperature specifications are within acceptable limits.

Compliance Considerations:

All substitute parts except the main 745183-3 are ROHS3 compliant. Selection should account for regulatory requirements in the target application and end-use market. The main part 745183-3 is REACH affected, while all substitute parts are REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5745183-3 be used as a direct replacement for 745183-3?

A: Yes. The 5745183-3 is electrically and mechanically equivalent to the 745183-3. Both parts have identical connector configuration (9-position D-Sub receptacle), current rating (6A), voltage rating (125V), operating temperature range (-55°C to 105°C), and solder termination. The primary difference is RoHS3 compliance status. The 5745183-3 is suitable for direct substitution when RoHS3 compliance is required or when the original part is unavailable.

Q: What are the key differences between the TE Connectivity 745183-3 and the NorComp 172-009 series?

A: The NorComp 172-009 series maintains the same 9-position D-Sub receptacle configuration and solder termination but differs in the following parameters: current rating (5A versus 6A), mounting type (panel mount capable versus through-hole only), shell finish (nickel plated versus tin plated), contact material (brass versus phosphor bronze), and dielectric material (PBT versus thermoplastic). The NorComp parts are ROHS3 compliant and have an extended upper operating temperature limit (125°C versus 105°C). Selection depends on whether the reduced current rating and alternative mounting options are acceptable for the application.

Q: Is the Mercury United Electronics 628-009-321-056 suitable for high-current applications?

A: No. The 628-009-321-056 has a current rating of 3A per contact, which is lower than the main part's 6A rating. This part is suitable only for applications where current requirements do not exceed 3A per contact. The 628-009-321-056 is designed for applications requiring shielding and board lock features within its specified current and temperature limits.

Q: What is the significance of the flange feature variations in the NorComp 172-009 series?

A: The flange feature determines the mounting interface and mechanical attachment method. The 172-009-283L001 has an unthreaded housing shell (similar to the main part), while 172-009-283L011 and 172-009-283L021 have board-side 4-40 threaded mounting, and 172-009-283L031 has mating-side 4-40 threaded mounting. Selection depends on the specific mounting requirements of the application and available board or panel space.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed (5745183-3, 172-009-283L001, 172-009-283L011, 172-009-283L021, 172-009-283L031, and 628-009-321-056) are ROHS3 compliant. The main part 745183-3 is RoHS non-compliant. Selection of a compliant substitute is necessary for applications subject to RoHS3 regulations.

Q: Can the NorComp 172-009 series be used in applications requiring 125V rating?

A: The NorComp 172-009 series does not specify a voltage rating in the provided data. The main part 745183-3 is rated for 125V. Applications requiring a specified 125V rating should use the TE Connectivity 745183-3 or 5745183-3, which both carry this rating.

Q: What is the difference in packaging between the main part and substitute parts?

A: The main part 745183-3 is packaged in tubes with 759 units in stock. The NorComp 172-009 series and Mercury United Electronics 628-009-321-056 are packaged in trays with varying inventory levels (917 to 3265 units). The TE Connectivity 5745183-3 is also tube packaged with 1861 units in stock. Packaging differences may affect handling, storage, and ordering procedures but do not affect electrical or mechanical compatibility.
