DC37S365TLF 37 Position D-Sub Receptacle Equivalent & Substitute Parts
Part Overview
The DC37S365TLF is a 37 position D-Sub receptacle connector manufactured by Amphenol ICC (FCI) with female sockets, designed for through-hole solder termination. This connector is actively produced and widely used in applications requiring robust D-Sub connectivity with a 37-pin configuration in a 2-row layout (Shell Size 4, DC/C designation). Substitute parts are necessary when addressing specific application requirements such as different flange configurations, operating temperature ranges, current ratings, or when managing supply chain alternatives from qualified manufacturers.

Substitute Part Grouping Explanation
Substitution of the DC37S365TLF is determined by strict equivalence in the following critical parameters:
- Connector Configuration: 37 positions, 2 rows, Shell Size 4 (DC/C), receptacle with female sockets
- Termination Method: Solder termination only
- Mounting: Through-hole mounting
- Electrical Performance: Current rating and voltage rating compatibility
- Environmental Compliance: RoHS and REACH status
- Operating Temperature Range: Must support the application's thermal requirements
- Flange Feature: Determines board integration method (Housing/Shell unthreaded, Board Side, or Mating Side configurations)
- Contact Material and Finish: Affects signal integrity and corrosion resistance
Substitute parts are grouped by flange configuration and operating temperature capability. Parts with identical core electrical specifications but different flange features (Housing/Shell unthreaded vs. Board Side vs. Mating Side) are considered direct substitutes for applications where the flange type is interchangeable. Parts with reduced operating temperature ranges or lower current ratings are listed but require application verification before selection.

Engineering Selection Recommendations
Primary Substitutes (Active Product Status, Full Compatibility)
The HARTING 09664516513 and 09664517513 are active production alternatives with identical 37-position, 2-row D-Sub configuration and through-hole solder termination. Both support the full operating temperature range of -55°C to 125°C matching the DC37S365TLF. The primary difference is flange configuration: mating side female screwlock versus the unthreaded housing shell of the original part. Selection depends on board integration requirements.
The TE Connectivity 1-5747301-4 (AMPLIMITE HD-20 series) is an active substitute with gold-plated contacts and tin-plated steel shell. Operating temperature is limited to -55°C to 105°C, which is 20°C below the DC37S365TLF maximum. Current rating is 6A, exceeding the 5A specification. This part is suitable for applications not requiring the full 125°C upper temperature limit.
Secondary Substitutes (Active Product Status, Panel Mount Configuration)
The NorComp 172-E series (172-E37-213R001, 172-E37-213R011, 172-E37-213R031, 172-E37-213R911) are active production parts with panel mount through-hole capability. These connectors support 5A current rating and operate from -50°C to 100°C, providing a narrower temperature window than the DC37S365TLF. Nickel-plated steel shells and gold contact finish are specified. Multiple flange options (unthreaded housing, board side, mating side, and dual-flange configurations) accommodate different mounting scenarios. These parts are suitable for panel-mounted applications where the reduced temperature range is acceptable.
Obsolete Alternatives (Not Recommended for New Designs)
The NorComp 172-037-212R001 and 172-037-212R011 are obsolete products. While electrically compatible with 5A current rating and -50°C to 100°C operating range, obsolete status indicates discontinued production and limited availability. These parts should not be selected for new designs.
Compliance Considerations
All listed substitutes maintain RoHS3 compliance and MSL 1 (unlimited moisture sensitivity level) status. REACH compliance is either unaffected or vendor-undefined across the substitute list. Selection should confirm REACH status with the specific manufacturer when required by application or regional regulations.
Frequently Asked Questions (FAQ)
Q: Can I substitute the DC37S365TLF with a HARTING 09664516513?
A: Yes, the HARTING 09664516513 is a direct functional substitute. Both are 37-position D-Sub receptacles with female sockets, through-hole solder termination, and support the full -55°C to 125°C operating range. The primary difference is the flange feature: the HARTING part has a mating side female screwlock (4-40) versus the unthreaded housing shell of the DC37S365TLF. Verify that your board design accommodates the mating side screwlock configuration before selection.
Q: What is the difference between the NorComp 172-E37-213R001 and 172-E37-213R011?
A: Both are 37-position D-Sub receptacles from the NorComp 172-E series with identical electrical specifications (5A current, -50°C to 100°C operating range, nickel-plated steel shell, gold contact finish). The difference is flange configuration: 172-E37-213R001 has an unthreaded housing shell flange, while 172-E37-213R011 has a board side (4-40) flange. Selection depends on whether your application requires panel mounting with an unthreaded shell or board-side mounting with threaded holes.
Q: Why does the TE Connectivity 1-5747301-4 have a lower maximum operating temperature than the DC37S365TLF?
A: The TE Connectivity part operates to 105°C maximum, while the DC37S365TLF operates to 125°C. This difference reflects the dielectric material and design specifications of each connector. The TE part is suitable for applications with maximum operating temperatures up to 105°C. If your application requires operation above 105°C, the DC37S365TLF or HARTING alternatives with full -55°C to 125°C range must be used.
Q: Are the NorComp 172-037-212R001 and 172-037-212R011 still available?
A: Both parts are listed as obsolete. While inventory may exist in distribution channels, these parts are no longer in active production. For new designs or long-term supply requirements, select from active production alternatives such as the NorComp 172-E series, HARTING, or TE Connectivity options.
Q: What does "Panel Mount, Through Hole" mean for the NorComp parts?
A: Panel mount through-hole indicates the connector is designed for installation through a panel or enclosure wall, with the connector body passing through the panel opening and secured via the flange feature (either unthreaded housing shell or threaded board-side/mating-side flanges). This differs from standard through-hole PCB mounting where the connector is soldered directly to a circuit board. Verify your application's mounting method before selecting panel mount variants.
Q: Can I use the HARTING 09644127235 if my application requires 300V operation?
A: No. The HARTING 09644127235 is rated for 100V maximum, while the DC37S365TLF is rated for 300V. If your application requires 300V operation, the DC37S365TLF or other substitutes with 300V or higher voltage rating must be used. The HARTING 09644127235 is suitable only for applications with maximum operating voltages up to 100V.
Q: What is the difference between gold contact finish and unspecified contact finish?
A: The DC37S365TLF specifies gold contact finish with GXT™ plating at 30.0µin (0.76µm) thickness, providing corrosion resistance and reliable signal transmission. Several HARTING substitutes list contact finish as unspecified (—), indicating this parameter is not provided in the technical data. When contact finish is critical to your application (such as in high-reliability or corrosive environments), select substitutes with specified gold or equivalent precious metal finishes.
