TE Connectivity 748482-5 D-Sub High Density 44 Position Receptacle Equivalent & Substitute Parts
Part Overview
The TE Connectivity AMP Connectors 748482-5 is a 44 Position D-Sub High Density Receptacle connector with female sockets, right-angle solder termination, and through-hole mounting. This connector is classified as obsolete product status. The AMPLIMITE HD-22 series connector features a steel nickel-plated shell with gold-plated contacts and is rated for 2A current at 125V operating voltage across a temperature range of -55°C to 105°C.
Due to the obsolete product status of the 748482-5, equivalent and substitute connectors from active manufacturers are necessary to maintain design continuity and ensure ongoing component availability for new production and field replacements.

Engineering Selection Recommendations
Primary Recommendation for Active Production:
The Amphenol ICC (FCI) ICD44S13E4GX00LF (part number 748482-5 equivalent) is the recommended substitute for new production applications. This connector maintains all critical functional parameters of the original TE Connectivity 748482-5 while offering the following advantages:
- Active product status ensures long-term availability and supply chain continuity
- ROHS3 compliance meets current regulatory requirements
- Operating temperature range of -55°C to 125°C exceeds the original specification
- Voltage rating of 300V provides enhanced electrical margin over the original 125V rating
- Current rating of 3A per contact exceeds the original 2A specification
- Solder termination and through-hole right-angle mounting are identical to the original design
Secondary Recommendations for Specific Applications:
For applications requiring extended operating temperature capability beyond 105°C, the ICD44S13E4GV00LF or ICD44S13E4GL00LF provide -55°C to 125°C operation with identical connector geometry and electrical characteristics.
For applications with panel mount or board edge mounting requirements, the Mercury United Electronics 634-044-263-042 or 634-044-268-032 provide compatible 44-position high-density D-Sub receptors with enhanced mounting flexibility while maintaining solder termination and core electrical specifications.
For applications requiring RoHS3 compliance with active product status, all Mercury United Electronics 634 series and Amphenol ICC ICD series substitutes meet this requirement.
Compliance Considerations:
Applications originally designed with the RoHS non-compliant 748482-5 may require design review if regulatory compliance has changed. All recommended substitutes from the Amphenol ICC ICD series and Mercury United Electronics 634 series offer ROHS3 compliance, eliminating potential regulatory barriers in new production.
Frequently Asked Questions (FAQ)
Q: Can the ICD44S13E4GX00LF directly replace the TE Connectivity 748482-5 in existing designs?
A: Yes. The ICD44S13E4GX00LF maintains all critical functional parameters: 44-position high-density D-Sub receptacle configuration, female socket contacts, 3-row layout, through-hole right-angle solder termination, steel nickel-plated shell, and gold contact finish. The connector footprint and mating interface are identical. The higher current rating (3A vs. 2A) and voltage rating (300V vs. 125V) provide additional electrical margin without requiring design modification.
Q: What is the difference between the Mercury United Electronics 634-044-263-042 and 634-044-263-043?
A: Both connectors share the same core 44-position high-density D-Sub receptacle configuration with identical electrical and mechanical specifications. The primary difference is packaging format: 634-044-263-042 is supplied in Tray packaging, while 634-044-263-043 is supplied without specified packaging. For production applications, the Tray-packaged 634-044-263-042 is preferred for automated assembly compatibility.
Q: Are there operating temperature limitations when substituting the 748482-5 with Mercury United Electronics 634 series connectors?
A: The Mercury United Electronics 634-044-263-042 and 634-044-268-032 have an operating temperature range of -55°C to 85°C, which is 20°C lower than the original 748482-5 specification of -55°C to 105°C. Applications requiring operation above 85°C must use the Amphenol ICC ICD series (rated to 125°C) or the NorComp 181-044-213R531 (rated to 105°C). The 634-044-663-041 and 634-044-663-043 are also limited to -55°C to 85°C operation.
Q: What is the significance of the flange feature differences between substitute parts?
A: The flange feature determines the mechanical mounting interface. The original 748482-5 uses Housing/Shell (4-40) threading. Substitutes with identical Housing/Shell (4-40) features (634-044-663-042, 634-044-263-042, 634-044-268-032, ICD44S13E4GX00LF) provide direct mechanical compatibility. The ICD44S13E4GL00LF uses Housing/Shell (M3) threading, requiring metric fasteners. The ICD44S13E4GV00LF and 634-044-663-043 use Mating Side Female Screwlock (4-40) features, which provide integrated locking without separate fasteners. The 634-044-663-041 uses unthreaded Housing/Shell, requiring alternative mounting methods.
Q: Does the contact material difference between Phosphor Bronze and Copper Alloy affect substitution compatibility?
A: Both Phosphor Bronze and Copper Alloy contact materials are acceptable for D-Sub high-density receptacle applications. The original 748482-5 uses Phosphor Bronze contacts. Substitutes with Copper Alloy contacts (634-044-263-042, 634-044-663-041, 634-044-663-043, ICD series) provide equivalent electrical performance and contact reliability. The choice between materials does not affect functional compatibility or mating interface characteristics.
Q: What packaging options are available for the substitute connectors?
A: Substitute connectors are supplied in multiple packaging formats: Bulk (ICD44S13E4GL00LF), Tray (181-044-213R531, 634-044-263-042, 634-044-268-032, 634-044-663-041, ICD44S13E4GX00LF), and Tube (634-044-663-043). Bulk packaging is suitable for high-volume automated assembly. Tray packaging provides organized component presentation for pick-and-place equipment. Tube packaging is appropriate for lower-volume manual assembly or field replacement applications. Selection should align with production assembly methodology and inventory management requirements.
Q: Are all substitute parts RoHS compliant?
A: The original TE Connectivity 748482-5 is RoHS non-compliant. All recommended substitutes from the Amphenol ICC ICD series (ICD44S13E4GV00LF, ICD44S13E4GX00LF) and Mercury United Electronics 634 series (634-044-263-042, 634-044-268-032, 634-044-663-041, 634-044-663-043) are ROHS3 compliant. The NorComp 181-044-213R531 is also ROHS3 compliant. Applications subject to RoHS regulations must use compliant substitutes. Applications without RoHS requirements may use any substitute from this reference.
Q: What is the inventory availability status for substitute parts?
A: All substitute connectors listed in this reference have confirmed inventory availability: Mercury United Electronics 634 series parts range from 705 to 1114 pieces in stock, NorComp 181-044-213R531 has 1400 pieces in stock, and Amphenol ICC ICD series parts range from 994 to 1308 pieces in stock. The original TE Connectivity 748482-5 has 786 pieces in stock but is obsolete. For new production, substitutes with active product status are recommended to ensure long-term supply continuity.
