Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with RoHS requirements, ensuring continued availability and regulatory compliance. The following considerations apply to part selection:

TE Connectivity 5746443-1: Primary specification with press-fit and solder termination capability. Supports extended operating temperature range of -65°C to 105°C. Phosphor bronze contact material with 30.0µin gold finish thickness on mating surfaces.

Amphenol ICC 53611-S10-6LF (Quickie™ Series): Solder termination only. Maintains 4-wall shrouding and square contact geometry. Phosphor bronze contacts with reduced mating finish thickness (15.0µin). Suitable for applications where press-fit termination is not required.

3M D3793-6302-AR (D3000 Series): Solder termination with long-hook fastening design. Brass contact material with reduced mating finish thickness (10.0µin). Operating temperature range -55°C to 105°C. Higher current rating of 1.75A per contact. ROHS3 compliant.

3M N3793-2302RB (3000 Series): Solder termination with long-hook fastening. 3-wall shrouding configuration. Copper alloy contacts with 30.0µin mating finish thickness. Operating temperature range -55°C to 105°C. 1.75A current rating.

3M N3793-6302RB (3000 Series): Solder termination with long-hook fastening and 4-wall shrouding. Copper alloy contacts with 30.0µin mating finish thickness. Operating temperature range -55°C to 105°C. 1.75A current rating.

3M N3793-6303RB (3000 Series): Solder termination with long-hook fastening and 4-wall shrouding. Copper alloy contacts with 30.0µin mating finish thickness. Extended contact post length (0.155" vs. 0.112"). Operating temperature range -55°C to 105°C. 1.75A current rating.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the TE Connectivity 5746443-1?

A: The following parameters must match exactly: 10-position, 2-row configuration with 0.100" (2.54mm) pitch spacing, male pin header type, through-hole mounting, shrouded 4-wall design, square contact shape, and UL94 V-0 flammability rating. All identified substitutes meet these core requirements.

Q: Can the Amphenol ICC 53611-S10-6LF be used as a direct replacement?

A: The 53611-S10-6LF is functionally compatible for applications requiring solder termination only. The main difference is the absence of press-fit termination capability present in the TE Connectivity 5746443-1. The 53611-S10-6LF features reduced mating contact finish thickness (15.0µin versus 30.0µin) and slightly shorter mating contact length (0.230" versus 0.240").

Q: What is the difference between the 3M N3793-6302RB and N3793-6303RB?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is the contact post length: N3793-6302RB features 0.112" post length while N3793-6303RB features 0.155" post length. Selection depends on specific PCB thickness and application requirements.

Q: Why do the 3M parts have a lower operating temperature minimum (-55°C versus -65°C)?

A: The 3M D3000 and 3000 series connectors are specified with a -55°C minimum operating temperature, which is within acceptable limits for most industrial and commercial applications. Applications requiring -65°C operation should specify the TE Connectivity 5746443-1 or verify 3M part compatibility with the application requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts are RoHS compliant or ROHS3 compliant, meeting current regulatory requirements for lead-free and restricted substance compliance.

Q: What is the significance of the "long" fastening hooks on the 3M parts?

A: The long-hook fastening design on 3M parts (D3793-6302-AR, N3793-2302RB, N3793-6302RB, N3793-6303RB) provides extended engagement length compared to standard hooks on the TE Connectivity 5746443-1. This design variation does not affect functional compatibility but may influence mating force characteristics and connector retention in specific applications.

Q: Can I use a 3-wall shrouded connector (N3793-2302RB) instead of a 4-wall shrouded connector?

A: The N3793-2302RB features 3-wall shrouding compared to the 4-wall shrouding of the TE Connectivity 5746443-1. While mechanically compatible, the reduced shrouding may affect EMI shielding characteristics and keying functionality. Application-specific requirements should be evaluated before substitution.

Q: What is the difference in contact material between the TE Connectivity and 3M parts?

A: The TE Connectivity 5746443-1 uses phosphor bronze contacts, while the Amphenol ICC 53611-S10-6LF also uses phosphor bronze. The 3M D3793-6302-AR uses brass contacts, and the 3M 3000 series (N3793-2302RB, N3793-6302RB, N3793-6303RB) use copper alloy contacts. All materials provide acceptable electrical conductivity and contact reliability for standard applications.

Q: Are there packaging differences between these parts?

A: Yes. The TE Connectivity 5746443-1 is supplied in bulk packaging, while the Amphenol ICC 53611-S10-6LF is supplied in tray packaging. The 3M parts are supplied in either bulk (N3793 series) or tray (D3793-6302-AR) packaging. Packaging selection may affect inventory management and handling procedures but does not affect connector functionality.
