TE Connectivity 1734530-6 D-Sub High Density Receptacle Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1734530-6 is a 15-position D-Sub high-density receptacle connector with female sockets, right-angle solder termination, and through-hole mounting. This connector is part of the AMPLIMITE HD-22 series and is classified as obsolete. The part features a nickel-plated steel shell, gold-plated contacts, and board lock functionality suitable for signal applications requiring 2A current capacity at 125V.

Due to the obsolete product status of the 1734530-6, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure ongoing component availability for production and field replacement applications.

Engineering Selection Recommendations

Primary Substitute Recommendation:

The ICD15S13E4GV00LF (Amphenol ICC FCI) and ICD15S13E4GX00LF (Amphenol ICC FCI) represent the most direct functional equivalents to the TE Connectivity 1734530-6. Both parts are active products with RoHS compliance, extended operating temperature ranges (-55°C ~ 125°C), and higher voltage ratings (300V). The ICD15S13E4GV00LF features mating-side female screwlock configuration matching the original part's flange design, while the ICD15S13E4GX00LF provides housing/shell flange configuration. Both maintain the critical 15-position, 3-row high-density D-Sub receptacle architecture with through-hole right-angle solder termination.

Secondary Substitute Options:

Mercury United Electronics 634 series parts (634-015-263-033, 634-015-663-042, 634-015-663-043, 634-015-263-040, and 634-015-563-012) provide active alternatives with ROHS3 compliance. These parts maintain full mechanical and electrical compatibility with the original specification. The 634-015-663-042 and 634-015-663-043 variants offer the closest feature alignment with board lock, mounting brackets, and shielding. The 634-015-563-012 variant supports panel mount applications in addition to through-hole mounting.

Extended Temperature Range Options:

The Amphenol ICC Commercial Products L17HTHES3F1C and L17HTHES3F4C connectors provide the highest operating temperature capability (-55°C ~ 150°C) with RoHS compliance. These parts feature stamped copper alloy contacts and glass-filled thermoplastic dielectric materials. The L17HTHES3F4C provides 30.0µin (0.76µm) gold contact finish thickness matching the original specification, while the L17HTHES3F1C provides flash finish. Both use M3 mating-side female screwlock fasteners rather than 4-40 fasteners.

Compliance Considerations:

All substitute parts listed maintain UL94 V-0 flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels consistent with the original part. All active substitute parts are RoHS compliant, addressing regulatory requirements for new production applications. The original 1734530-6 is classified as obsolete; therefore, selection of active substitute parts ensures long-term component availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the ICD15S13E4GV00LF directly replace the TE Connectivity 1734530-6 in existing designs?

A: Yes. The ICD15S13E4GV00LF maintains identical 15-position, 3-row high-density D-Sub receptacle configuration, right-angle through-hole solder termination, 0.350" backset spacing, and mating-side female screwlock (4-40) flange design. The higher current rating (3A vs. 2A), extended voltage rating (300V vs. 125V), and extended operating temperature range (-55°C ~ 125°C vs. -55°C ~ 105°C) provide enhanced performance margins without requiring design modification.

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

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is the flange feature: the ICD15S13E4GV00LF provides mating-side female screwlock (4-40) configuration, while the ICD15S13E4GX00LF provides housing/shell (4-40) configuration. Selection depends on the specific mounting interface requirements of the application.

Q: Are Mercury United Electronics 634 series parts suitable substitutes?

A: Yes. The Mercury 634 series parts (634-015-263-033, 634-015-663-042, 634-015-663-043, 634-015-263-040, and 634-015-563-012) are active products with ROHS3 compliance that maintain full compatibility with the 1734530-6 specification. These parts feature 3A per contact current ratings and extended operating temperature ranges. Specific variants offer board lock, mounting brackets, and shielding features. The 634-015-563-012 supports panel mount applications in addition to through-hole mounting.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging configurations: Bulk packaging (634-015-263-033, 634-015-263-040, ICD15S13E4GX00LF), Tray packaging (634-015-663-042, 634-015-663-043, 634-015-263-043, ICD15S13E4GV00LF, L17HTHES3F1C, L17HTHES3F4C), and standard packaging. Selection of packaging type depends on production volume requirements and inventory management practices.

Q: Do substitute parts maintain the same contact finish specifications?

A: Substitute parts maintain gold contact finish consistent with the original 1734530-6. Contact finish thickness varies: the original part specifies 30.0µin (0.76µm), while substitute parts offer either flash finish or 30.0µin (0.76µm) thickness. The 634-015-663-042, 634-015-663-043, L17HTHES3F4C, and 1734530-6 all specify 30.0µin (0.76µm) thickness. Flash finish alternatives (634-015-263-033, 634-015-263-040, ICD15S13E4GV00LF, ICD15S13E4GX00LF, L17HTHES3F1C) provide equivalent corrosion protection with reduced material thickness.

Q: What are the temperature operating range differences among substitute options?

A: The original 1734530-6 operates from -55°C to 105°C. Mercury 634 series parts operate from -55°C to 85°C, providing a reduced upper temperature limit. Amphenol ICD series parts operate from -55°C to 125°C, extending the upper limit by 20°C. Amphenol L17HT series parts operate from -55°C to 150°C, providing the highest temperature capability. Selection depends on application thermal requirements.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are RoHS compliant (either ROHS3 or full RoHS compliance). The original 1734530-6 is classified as "Not applicable" for RoHS status due to its obsolete classification. For new production applications requiring RoHS compliance, all listed substitute parts satisfy regulatory requirements.

Q: What is the current rating difference between the original part and substitutes?

A: The original 1734530-6 is rated at 2A. All substitute parts are rated at 3A (either 3A per contact or 3A total), providing 50% higher current capacity. This enhanced rating does not require design modification and provides additional performance margin for signal applications.

Q: Can the L17HTHES3F1C and L17HTHES3F4C be used in applications requiring 4-40 fasteners?

A: The L17HTHES3F1C and L17HTHES3F4C feature M3 mating-side female screwlock fasteners rather than 4-40 fasteners. These parts are suitable for applications where M3 fastener compatibility exists. For applications requiring 4-40 fasteners, the ICD15S13E4GV00LF, 634-015-263-033, 634-015-663-043, or 634-015-263-043 are appropriate selections.

Q: What dielectric material differences exist among substitute options?

A: The original 1734530-6 uses polyamide (PA9T) nylon 9T dielectric. Mercury 634 series parts use polyester thermoplastic dielectric. Amphenol ICD series parts use polyester dielectric. Amphenol L17HT series parts use thermoplastic glass-filled dielectric. All materials maintain UL94 V-0 flammability ratings and provide equivalent electrical insulation performance.
