Engineering Selection Recommendations
Primary Substitutes (Highest Compatibility):
The TE Connectivity AMP Connectors parts 5747375-2, 5747375-8, and 747375-2 provide the closest electrical and mechanical equivalence to the L717DC37PV. These parts maintain identical connector geometry (37 positions, 2 rows, 4 (DC, C) shell size), through-hole mounting, solder termination, steel tin-plated shells, gold-plated brass contacts, and UL94 V-0 flammability rating. All three are ROHS3 compliant. The primary difference is a reduced current rating (6A versus 7.5A) and lower voltage rating (125V versus 300V). These substitutes are suitable for applications operating within the 6A and 125V specifications.
Secondary Substitutes (Panel Mount Variants):
The NorComp Inc. 172-E series connectors (172-E37-113R001, 172-E37-113R011, 172-E37-113R911) are panel mount variants with identical 37-position, 2-row, 4 (DC, C) configurations. These parts feature nickel-plated steel shells and gold-plated brass contacts. They are ROHS3 compliant and UL94 V-0 rated. The current rating is 5A and operating temperature range is -50°C to 100°C. These substitutes are appropriate for applications requiring panel-mounted connector configurations with reduced current and temperature specifications.
Alternative Termination (Press-Fit):
The TE Connectivity AMP Connectors part 5786534-1 offers press-fit termination as an alternative to solder termination. This part maintains the 37-position, 2-row, 4 (DC, C) configuration with through-hole mounting, steel tin-plated shell, and gold-plated copper alloy contacts. It is ROHS3 compliant and UL94 V-0 rated. Press-fit termination eliminates soldering requirements and is suitable for automated assembly processes.
HARTING Alternative:
The HARTING part 09654616713 provides a through-hole solder-terminated option with 37 positions, 2 rows, and 4 (DC, C) shell size. It features a steel shell, copper alloy contacts, and is ROHS3 compliant with UL94 V-0 rating. Current rating is 6.5A. This part is suitable for applications requiring HARTING connector compatibility.
Compliance Considerations:
The L717DC37PV is RoHS Compliant. Most substitute parts are ROHS3 Compliant, which represents an updated compliance standard. The TE Connectivity AMP Connectors part 747375-2 is RoHS non-compliant and should be selected only when legacy compliance status is required. All listed substitutes maintain UL94 V-0 flammability certification.
Frequently Asked Questions (FAQ)
Q: Can the L717DC37PV be directly replaced with a TE Connectivity 5747375-2?
A: The 5747375-2 is mechanically and electrically compatible for applications operating at 6A or less and 125V or less. Both connectors share identical 37-position, 2-row, 4 (DC, C) configurations with through-hole solder termination, steel tin-plated shells, and gold-plated brass contacts. The L717DC37PV has higher current (7.5A) and voltage (300V) ratings. If your application requires the full 7.5A or 300V specifications, the 5747375-2 is not suitable.
Q: What is the difference between the NorComp 172-E37-113R001 and 172-E37-113R011?
A: Both parts are 37-position D-Sub plugs with identical electrical specifications (5A current, UL94 V-0, ROHS3 compliant). The primary difference is the flange feature: 172-E37-113R001 has an unthreaded housing/shell flange, while 172-E37-113R011 has a board-side 4-40 threaded flange. The 172-E37-113R911 variant adds mating-side female screwlock (4-40) and board lock features. Select based on your specific mounting and locking requirements.
Q: Why would I choose the 5786534-1 press-fit variant over solder-terminated options?
A: Press-fit termination (5786534-1) eliminates the soldering process, reducing assembly time and thermal stress on the connector and circuit board. This termination method is preferred in high-volume automated assembly environments and applications where soldering is not feasible. The 5786534-1 maintains the same 37-position, 2-row, 4 (DC, C) configuration as the L717DC37PV.
Q: Are all substitute parts packaged identically to the L717DC37PV?
A: No. The L717DC37PV is packaged in trays. Substitute parts are packaged in trays, tubes, or bulk configurations depending on the manufacturer and part number. Verify packaging requirements for your procurement and handling processes. Packaging does not affect electrical or mechanical compatibility.
Q: What is the significance of the contact material differences (Brass, Copper Alloy, Phosphor Bronze)?
A: All three contact materials (Brass, Copper Alloy, Phosphor Bronze) are acceptable for D-Sub signal connectors and provide similar electrical performance. Brass is the most common and cost-effective. Phosphor Bronze (5787686-1) offers enhanced spring properties and durability in high-cycle mating applications. Copper Alloy (09654616713, 5786534-1) provides similar performance to brass. Selection is based on application requirements and availability.
Q: Can I use a NorComp 172-E37 connector in a through-hole vertical mounting application?
A: The NorComp 172-E37 series is specified as panel mount with through-hole capability. While the connector can be mounted vertically through a hole, it is designed for panel-mounted applications. For standard vertical through-hole mounting without panel integration, the TE Connectivity AMPLIMITE series (5747375-2, 5747375-8, 747375-2) or the Amphenol L717DC37PV are more appropriate selections.
Q: What is the difference between RoHS Compliant and ROHS3 Compliant?
A: RoHS Compliant refers to the original Restriction of Hazardous Substances directive compliance. ROHS3 Compliant refers to the updated RoHS 3 directive (2015/863/EU), which includes additional restricted substances. ROHS3 is the current standard. The L717DC37PV is RoHS Compliant (original standard), while most substitutes are ROHS3 Compliant (updated standard). Both are acceptable; ROHS3 represents more stringent environmental requirements.
Q: Is the L717DC37PV suitable for applications requiring -55°C to 125°C operation?
A: Yes. The L717DC37PV is rated for -55°C to 125°C continuous operation. Most TE Connectivity substitutes are rated -55°C to 105°C, which is narrower. The NorComp 172-E37 series is rated -50°C to 100°C. If your application requires the full -55°C to 125°C range, the L717DC37PV or equivalent Amphenol parts are required.
Q: Can I substitute the L717DC37PV with the HARTING 09654616713 in a legacy system?
A: Yes, provided your application operates within the HARTING part specifications: 6.5A current, -55°C to 125°C operating temperature, UL94 V-0 flammability, and ROHS3 compliance. Both connectors share the 37-position, 2-row, 4 (DC, C) D-Sub configuration with through-hole solder termination. Verify that the copper alloy contacts and steel shell (without specified finish) are compatible with your system requirements.
