Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the TE Connectivity 1734344-5 is based on the following mandatory matching parameters:

Core Compatibility Parameters:

• Connector configuration: 15-position D-Sub high-density receptacle with female sockets
• Shell size and layout: 1 (DE, E) high-density format
• Mounting method: Through-hole, right-angle orientation
• Termination type: Solder
• Backset spacing: 0.350" (8.89mm)
• Material flammability: UL94 V-0 rating

Electrical Performance Parameters:

• Current rating: Minimum 2A per contact (substitutes rated 3A are acceptable as higher capacity)
• Voltage rating: Minimum 125V (substitutes rated 250V or 300V are acceptable as higher capacity)
• Operating temperature range: Must encompass or overlap -55°C to 130°C

Compliance Parameters:

• RoHS compliance status: RoHS Compliant or ROHS3 Compliant
• Moisture sensitivity level: MSL 1 (Unlimited)

Substitute parts identified below meet all core compatibility parameters and maintain or exceed electrical performance specifications. Variations in shell finish (nickel vs. tin plating), contact material composition (phosphor bronze vs. copper alloy vs. brass), and flange feature design (mating side vs. board side vs. housing/shell) do not prevent functional substitution when core parameters align.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and meet or exceed the core electrical and mechanical specifications of the TE Connectivity 1734344-5. Selection among substitutes is based on the following engineering criteria:

Direct Electrical Equivalents (Recommended for Drop-In Replacement):

The Amphenol ICC ICD15S13E4GV00LF and ICD15S13E4GX00LF (FCI series) provide the closest electrical match with 3A current rating and 300V voltage rating, exceeding the original 2A/125V specification. Both maintain the mating-side female screwlock flange feature and through-hole right-angle mounting. These parts are RoHS Compliant with unlimited MSL and are suitable for direct substitution in applications requiring higher electrical headroom.

Temperature-Constrained Applications:

The Mercury 634-015-263-042 operates to 85°C maximum, which is below the original part's 130°C upper limit. This substitute is suitable only for applications with operating temperatures not exceeding 85°C. The Amphenol L77HDE15 series (L77HDE15SD1CH4FVGA, L77HDE15SD1CH4R, L77HDE15SD1CH4RC309) operates to 105°C maximum, also below the original specification. These parts are appropriate for applications with maximum operating temperatures of 105°C or lower.

Shell Finish Considerations:

The original TE Connectivity part features nickel-plated steel shell. Substitutes with tin-plated steel shell (Amphenol L77HDE15 series) provide equivalent corrosion protection and electrical performance in standard industrial environments. The Mercury 634-015-263-042 maintains nickel plating, matching the original finish specification.

Compliance and Regulatory Status:

All substitute parts are RoHS Compliant or ROHS3 Compliant, meeting current regulatory requirements. The Amphenol ICC parts carry REACH Unaffected status, indicating no REACH-restricted substances. The TE Connectivity original part lists REACH status as Vendor Undefined. All parts are classified under ECCN EAR99 and HTSUS 8536.69.4040.

Packaging and Inventory:

Substitute parts are available in Tray or Bulk packaging. The Amphenol L77HDE15SD1CH4FVGA offers the highest current inventory (2281 pcs), followed by L77HDE15SD1CH4RC309 (2064 pcs) and ICD15S13E4GV00LF (2242 pcs), providing supply continuity for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the Mercury 634-015-263-042 be used as a direct replacement for the TE Connectivity 1734344-5?

A: The Mercury 634-015-263-042 is mechanically and electrically compatible for applications operating at temperatures up to 85°C. The original TE Connectivity part is rated to 130°C. If your application requires operation above 85°C, the Mercury substitute is not suitable. For applications within the 85°C limit, the Mercury part provides equivalent 15-position D-Sub HD receptacle functionality with higher current capacity (3A vs. 2A).

Q: What is the difference between the Amphenol ICD15S13E4GV00LF and ICD15S13E4GX00LF?

A: Both parts are electrically identical 15-position D-Sub HD receptacles with 3A current rating and 300V voltage rating. The primary difference is the flange feature: ICD15S13E4GV00LF has a mating-side female screwlock (4-40), while ICD15S13E4GX00LF has a housing/shell flange (4-40). Select based on your PCB mounting hole configuration and mechanical fastening requirements.

Q: Are the Amphenol L77HDE15 series parts suitable for high-temperature applications?

A: The Amphenol L77HDE15 series (L77HDE15SD1CH4FVGA, L77HDE15SD1CH4R, L77HDE15SD1CH4RC309) operates to a maximum of 105°C. The original TE Connectivity 1734344-5 operates to 130°C. For applications requiring operation above 105°C, the L77HDE15 series is not suitable. For applications with maximum operating temperatures of 105°C or lower, these parts provide equivalent functionality with enhanced current capacity (3A vs. 2A).

Q: What is the significance of contact finish thickness differences?

A: The original TE Connectivity 1734344-5 specifies 15.0µin (0.38µm) gold contact finish thickness. Most substitutes specify flash thickness, which is thinner but still provides adequate contact resistance and durability for standard applications. The Amphenol L77HDE15SD1CH4RC309 specifies 30.0µin (0.76µm), providing thicker gold plating. For applications with stringent contact durability or corrosion resistance requirements, the thicker 30.0µin specification is preferred.

Q: Can I use a substitute part with a different shell finish (tin vs. nickel plating)?

A: Yes. Both nickel-plated and tin-plated steel shells provide equivalent corrosion protection and electrical performance in standard industrial environments. The choice between nickel and tin plating does not affect functional compatibility. Select based on your specific environmental requirements and existing connector inventory standards.

Q: What packaging options are available for substitute parts?

A: Substitute parts are supplied in Tray or Bulk packaging. Tray packaging is standard for most Amphenol ICC parts and the Mercury 634-015-263-042. The Amphenol ICD15S13E4GX00LF is available in Bulk packaging. Confirm packaging requirements with your procurement specifications before ordering.

Q: Are all substitute parts RoHS Compliant?

A: Yes. All identified substitute parts are either RoHS Compliant or ROHS3 Compliant, meeting current regulatory requirements for lead-free and restricted substance compliance. The original TE Connectivity 1734344-5 is RoHS Compliant. All parts meet current environmental and regulatory standards.

Q: What is the moisture sensitivity level (MSL) for substitute parts?

A: All substitute parts, including the original TE Connectivity 1734344-5, are rated MSL 1 (Unlimited). This indicates no moisture sensitivity restrictions and no special storage or handling requirements. Parts can be stored and handled under standard industrial conditions without moisture-related degradation.
