Engineering Selection Recommendations
Primary Recommendation: TE Connectivity 2311586-4
The 2311586-4 is the direct active-product equivalent from TE Connectivity, the original manufacturer of the 1734344-1. This part maintains the AMPLIMITE HD-22 series designation and provides identical mechanical and electrical compatibility. The 2311586-4 features a 3A current rating (50% higher than the original 2A specification), providing additional design margin. Operating temperature range is -55°C to 105°C, which covers the lower portion of the original specification. This part is actively manufactured and widely available with 6360 units in stock.
Secondary Recommendations by Application Category:
For applications requiring extended temperature operation (-55°C to 130°C or higher):
- L17HTHES4F1CVGA (Amphenol ICC): Extends operating range to -55°C to 150°C, rated 3A, 300V, RoHS compliant. Suitable for high-temperature environments.
For applications requiring higher voltage ratings:
- ICD15S13E4GV00LF or ICD15S13E4GX00LF (Amphenol ICC FCI): Both rated 300V (versus 125V original), 3A current, -55°C to 125°C operating range, RoHS compliant. Provides voltage margin for industrial applications.
For panel-mount applications:
- 634-015-563-012 (Mercury United Electronics): Supports panel mount configuration in addition to through-hole, 3A rated, -55°C to 105°C, RoHS compliant.
For board-edge mounting applications:
- 634-015-263-033, 634-015-263-040, or 634-015-263-042 (Mercury United Electronics): All support board-edge mounting in addition to through-hole, 3A rated, -55°C to 85°C, RoHS compliant.
All recommended substitutes maintain ROHS3 or RoHS compliance and MSL 1 rating. Selection should be based on specific application requirements for mounting configuration, temperature range, and voltage rating.
Frequently Asked Questions (FAQ)
Q: Can the 2311586-4 be used as a direct replacement for the 1734344-1?
A: Yes. The 2311586-4 is mechanically and electrically compatible with the 1734344-1. Both are 15-position D-Sub high-density receptors with identical shell size, backset spacing, and solder termination. The 2311586-4 provides enhanced current rating (3A versus 2A) and is actively manufactured.
Q: What is the difference between the Mercury United Electronics 634-015-263-033, 634-015-263-040, and 634-015-263-042 parts?
A: These three parts differ in flange configuration and packaging. The 634-015-263-033 features a mating-side female screwlock flange, the 634-015-263-040 features a mating-side flange, and the 634-015-263-042 features a housing/shell flange. All three support board-edge and through-hole mounting and are electrically identical (3A, -55°C to 85°C). Selection depends on the specific flange and mounting requirements of the application.
Q: Why do some substitute parts have lower maximum operating temperatures than the original 1734344-1?
A: The 1734344-1 specifies -55°C to 130°C. Several substitute parts (Mercury United Electronics 634 series) are rated only to 85°C maximum. These parts are suitable for applications operating within the -55°C to 85°C range. For applications requiring the full -55°C to 130°C range, select the 2311586-4 (-55°C to 105°C) or L17HTHES4F1CVGA (-55°C to 150°C).
Q: Are all substitute parts RoHS compliant?
A: Yes. All listed substitute parts are either ROHS3 compliant or RoHS compliant, meeting current environmental regulations.
Q: What is the difference between the Amphenol ICC ICD15S13E4GV00LF and ICD15S13E4GX00LF?
A: Both parts are electrically and mechanically identical (15-position, 3A, 300V, -55°C to 125°C, RoHS compliant). The primary difference is flange configuration: the ICD15S13E4GV00LF features a mating-side female screwlock flange, while the ICD15S13E4GX00LF features a housing/shell flange. Selection depends on the specific mounting and mating requirements of the application.
Q: Can I use the L77HDE15SD1CH3FC309 or L77HDE15SD1CH3RC309 in place of the 1734344-1?
A: Yes, with the following considerations. Both parts are mechanically compatible 15-position D-Sub high-density receptors with 3A current rating and solder termination. Operating temperature is -55°C to 105°C, which covers most of the original -55°C to 130°C range. The L77HDE15SD1CH3FC309 features a mating-side female screwlock flange (M3), while the L77HDE15SD1CH3RC309 features a board-side flange (M3). Both are RoHS compliant and actively manufactured.
Q: What packaging options are available for substitute parts?
A: Substitute parts are available in bulk, tray, and tape packaging configurations. The 2311586-4 is supplied in bulk packaging. Mercury United Electronics 634 series parts are available in bulk or tray. Amphenol ICC parts are available in tray or bulk. Packaging selection should be based on assembly process requirements and order quantity.
Q: Are all substitute parts rated for 3A current?
A: Most substitute parts are rated 3A. The original 1734344-1 is rated 2A. The 3A rating of substitute parts provides 50% additional current capacity and is fully compatible with applications designed for 2A operation.
Q: What is the significance of the contact finish thickness specifications?
A: Contact finish thickness affects durability and mating cycle life. The original 1734344-1 specifies flash gold plating. Substitute parts specify either flash plating or specific thickness values (10.0µin or 30.0µin). All specifications meet industry standards for D-Sub connectors and are suitable for general signal applications.
