Substitute Part Grouping Explanation
Substitute parts for the TE Connectivity 5749639-2 are selected based on strict electrical and mechanical compatibility criteria. The following parameters must align for functional substitution:
Critical Matching Parameters:
- 62-position connector configuration
- D-Sub high-density format with 3-row layout
- Shell size 4 (DC, C) high-density specification
- Through-hole, right-angle mounting orientation
- Solder termination method
- 0.350" (8.89mm) backset spacing
- Operating temperature range -55°C to 105°C
- UL94 V-0 flammability rating
Acceptable Variation Parameters:
- Current rating (original 2A; substitutes rated 3A provide higher capacity)
- Voltage rating (original 125V; substitutes rated 250V provide higher capacity)
- Shell material finish (nickel-plated vs. tin-plated)
- Contact material (phosphor bronze vs. brass)
- Contact finish thickness (flash vs. specified µin values)
- Flange feature configuration (housing/shell vs. board-side vs. mating-side mounting)

Engineering Selection Recommendations
Primary Substitutes (Amphenol ICC L717HDC62 Series)
The Amphenol ICC L717HDC62 series connectors represent the most direct functional equivalents to the TE Connectivity 5749639-2. These parts are active products with RoHS compliance, addressing the obsolescence of the original part while maintaining electrical and mechanical compatibility. The L717HDC62 series offers enhanced electrical ratings (3A current, 250V voltage) compared to the original specification, providing improved performance margins for existing applications.
Selection within the L717HDC62 series depends on flange configuration requirements:
- L717HDC62PD1CH3F / L717HDC62PD1CH3FC309: Mating-side female screwlock (M3) flange
- L717HDC62PD1CH3R / L717HDC62PD1CH3RC309: Board-side (M3) flange
- L717HDC62PD1CH4FC309: Mating-side female screwlock (4-40) flange
- L717HDC62PD1CH4R / L717HDC62PD1CH4RC309: Board-side (4-40) flange
The 4-40 flange variants (L717HDC62PD1CH4R and L717HDC62PD1CH4RC309) provide the closest mechanical alignment to the original 5749639-2 housing/shell (4-40) configuration.
Secondary Substitutes (Amphenol ICC L777HDC62 Series)
The L777HDC62PD1CH3F connector offers an alternative with identical core specifications to the L717HDC62 series but represents a distinct product line. This part is active and RoHS compliant.
Mercury United Electronics 633 Series
The Mercury 633-062-263-032 and 633-062-263-043 connectors provide functional equivalence based on 62-position, high-density D-Sub configuration and solder termination. Detailed electrical and mechanical specifications for these parts are not fully provided in the available data; however, both are listed as in-stock alternatives.
Compliance Considerations
The original TE Connectivity 5749639-2 carries "Not applicable" RoHS status due to its obsolete classification. All Amphenol ICC substitutes are RoHS compliant (RoHS or ROHS3), meeting current regulatory requirements for new designs and production environments subject to RoHS directives.
Frequently Asked Questions (FAQ)
Q: Can the Amphenol ICC L717HDC62PD1CH4R directly replace the TE Connectivity 5749639-2?
A: Yes. The L717HDC62PD1CH4R maintains all critical mechanical and electrical parameters: 62-position high-density D-Sub configuration, 3-row layout, through-hole right-angle solder termination, 0.350" backset spacing, and -55°C to 105°C operating range. The board-side 4-40 flange configuration matches the original housing/shell mounting. The higher current (3A vs. 2A) and voltage (250V vs. 125V) ratings provide enhanced performance margins.
Q: What is the difference between L717HDC62PD1CH3R and L717HDC62PD1CH4R?
A: The primary difference is the flange feature. The CH3R variant uses M3 board-side mounting, while the CH4R variant uses 4-40 board-side mounting. The 4-40 configuration aligns with the original 5749639-2 specification. Both maintain identical electrical ratings and core connector architecture.
Q: Why do some Amphenol substitutes have "C309" in the part number?
A: The "C309" suffix indicates a specific packaging or configuration variant within the Amphenol product line. Parts with and without this suffix maintain identical electrical and mechanical specifications; the suffix denotes internal manufacturing or supply chain designation. Both variants are functionally equivalent for substitution purposes.
Q: What is the difference between mating-side and board-side flange configurations?
A: Mating-side flanges (female screwlock) are located on the connector face and interface with the mating connector. Board-side flanges are mounted to the printed circuit board or panel. The original 5749639-2 uses a housing/shell board-side configuration. For direct mechanical replacement, select board-side variants (L717HDC62PD1CH3R, L717HDC62PD1CH4R, or their C309 equivalents).
Q: Are there differences in contact finish thickness between substitutes?
A: Yes. The original 5749639-2 specifies 15.0µin (0.38µm) gold contact finish. Amphenol substitutes vary: flash finish (no specified thickness), 16.0µin (0.41µm), or 30.0µin (0.76µm). All finishes provide gold plating for corrosion resistance and electrical performance. Thicker finishes (30.0µin) offer extended contact life in high-cycle applications.
Q: What is the significance of RoHS compliance for these substitutes?
A: RoHS compliance indicates the connector meets Restriction of Hazardous Substances directives, restricting lead, cadmium, mercury, and other hazardous materials. All Amphenol ICC substitutes are RoHS compliant, making them suitable for applications and markets requiring regulatory compliance. The original TE part carries "Not applicable" status due to obsolescence.
Q: Can I use Mercury 633 series connectors as substitutes?
A: The Mercury 633-062-263-032 and 633-062-263-043 connectors maintain the 62-position high-density D-Sub solder-terminated architecture. However, detailed electrical specifications (current rating, voltage rating, operating temperature) are not provided in available documentation. These parts are functionally compatible based on connector format but should be evaluated against specific application requirements before selection.
Q: What is the inventory status of these substitutes?
A: All listed substitutes are in-stock: Mercury 633-062-263-032 (769 pcs), Mercury 633-062-263-043 (915 pcs), and Amphenol ICC variants ranging from 650 to 1,144 pcs. The highest inventory availability is L717HDC62PD1CH4RC309 (1,144 pcs) and L717HDC62PD1CH4R (1,101 pcs).
Q: Are there any mechanical compatibility issues when substituting these connectors?
A: All substitutes maintain identical backset spacing (0.350" / 8.89mm), shell size (4 DC/C high-density), and through-hole right-angle mounting orientation. Mechanical compatibility is assured for PCB layout and mating connector interfaces. Flange configuration differences (M3 vs. 4-40, board-side vs. mating-side) affect mounting methodology but do not impact electrical performance or connector interface compatibility.
