TE Connectivity 1-338316-2 D-Sub 37 Position Receptacle Equivalent & Substitute Parts
Part Overview
The TE Connectivity 1-338316-2 is a 37 position D-Sub receptacle connector with female sockets, vertical solder termination, and through-hole mounting. This connector is part of the AMPLIMITE HDP-20 series and features a 4-position shell size (DC, C) with board lock functionality. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support, maintenance, and production continuity. Substitute connectors must maintain electrical and mechanical compatibility while meeting the same performance specifications for 37-position D-Sub receptacle applications.

Engineering Selection Recommendations
Primary Recommendation: TE Connectivity 2-5747709-0
The TE Connectivity 2-5747709-0 is the direct successor to the 1-338316-2 within the same manufacturer's product line. This part maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. The 2-5747709-0 is packaged in tubes with 1537 units in stock, providing immediate availability. This connector is the preferred choice for direct replacement in new designs and production continuity.
Secondary Recommendation: HARTING 09664556513
The HARTING 09664556513 provides cross-manufacturer compatibility with enhanced operating temperature range (-55°C to 125°C) and higher current rating (6.5A). This part features board lock functionality matching the original specification and is available in bulk packaging with 1128 units in stock. ROHS3 compliance and REACH unaffected status support regulatory requirements. This connector is suitable for applications requiring extended thermal performance.
Alternative Recommendation: NorComp Inc. 191-037-213L001
The NorComp Inc. 191-037-213L001 offers active product status with shielded construction and extended operating temperature range (-55°C to 125°C). This part features nickel-plated steel shell and phosphor bronze contacts matching the original material specifications. With 1105 units in stock, this connector provides an alternative for applications requiring shielded D-Sub receptacle functionality.
Considerations for NorComp 172 Series (Obsolete):
The NorComp 172-037-212R001, 172-037-212R011, and 172-037-212R911 are classified as obsolete. While these parts meet the critical electrical and mechanical parameters, their obsolete status limits long-term availability and support. These connectors are suitable only for legacy system maintenance where exact form-factor compatibility is required.
Current Rating Consideration:
The NorComp series connectors (172-037 and 191-037) are rated at 5A, which is lower than the original 6A specification. Applications requiring the full 6A current capacity should select TE Connectivity 2-5747709-0 or HARTING alternatives rated at 6A or 6.5A.
Frequently Asked Questions (FAQ)
Q: Can I use HARTING 09664516513 or 09664517513 as direct replacements for the TE Connectivity 1-338316-2?
A: Yes. Both HARTING parts meet all critical substitution parameters: 37-position receptacle, female sockets, 2-row configuration, shell size 4 (DC, C), through-hole solder termination, UL94 V-0 flammability rating, and MSL 1. Both parts feature board lock functionality and are rated at 6.5A with extended operating temperature to 125°C. The primary difference is packaging: 09664516513 is supplied in trays (989 units in stock), while 09664517513 is supplied in bulk (1009 units in stock).
Q: What is the difference between the TE Connectivity 2-5747709-0 and the original 1-338316-2?
A: The 2-5747709-0 is the active production replacement for the obsolete 1-338316-2. Both connectors share identical electrical and mechanical specifications: 37 positions, 2 rows, shell size 4 (DC, C), 6A current rating, -55°C to 105°C operating temperature, and UL94 V-0 flammability rating. The 2-5747709-0 offers improved product status (active), RoHS compliance, and higher inventory availability (1537 units). The 2-5747709-0 is packaged in tubes, while the original packaging for 1-338316-2 is not specified.
Q: Why do some substitute parts have a 5A current rating instead of 6A?
A: The NorComp 172-037 and 191-037 series connectors are rated at 5A due to different contact design and material specifications. While these parts maintain mechanical and electrical compatibility for 37-position D-Sub receptacle applications, applications requiring the full 6A current capacity must select TE Connectivity 2-5747709-0 or HARTING alternatives (09664156503, 09664516513, 09664517513, 09664556513, 09664557513) rated at 6A or 6.5A.
Q: Are all substitute parts RoHS compliant?
A: The TE Connectivity 2-5747709-0 is RoHS compliant. All HARTING parts (09664156503, 09664516513, 09664517513, 09664556513, 09664557513) are ROHS3 compliant. All NorComp parts (172-037-212R001, 172-037-212R011, 172-037-212R911, 191-037-213L001) are ROHS3 compliant. The original 1-338316-2 RoHS status is vendor undefined.
Q: What is the difference between panel mount and through-hole mounting in the NorComp alternatives?
A: The NorComp 172-037 series connectors feature panel mount, through-hole mounting, which allows installation through a panel opening with solder termination on the board side. The original 1-338316-2 and primary substitutes (TE Connectivity 2-5747709-0 and HARTING parts) feature standard through-hole mounting without panel mount capability. Panel mount variants are suitable for applications requiring front-panel connector installation.
Q: Can I substitute a shielded connector (NorComp 191-037-213L001) for the unshielded original?
A: Yes, mechanically and electrically. The NorComp 191-037-213L001 is a shielded variant that maintains all critical substitution parameters. However, shielded connectors have different mechanical dimensions and may require design modifications to accommodate the shield structure. Shielded variants are suitable for applications requiring electromagnetic interference (EMI) protection.
Q: What is the significance of the contact finish thickness specification?
A: The TE Connectivity 2-5747709-0 specifies contact finish thickness of 30.0µin (0.76µm), providing defined wear and corrosion resistance characteristics. The original 1-338316-2 does not specify contact finish thickness. HARTING and NorComp parts do not specify contact finish thickness. Contact finish thickness affects long-term reliability in high-cycle mating applications; thicker finishes provide extended service life.
Q: Are HARTING and NorComp connectors mechanically interchangeable with TE Connectivity connectors?
A: Yes. All substitute parts maintain identical shell size (4, DC, C), 37-position configuration, 2-row layout, and solder termination. Mechanical interchangeability is confirmed by matching these critical parameters. However, minor variations in flange feature design (housing/shell versus mating side screwlock) may affect mounting hardware compatibility. Physical verification is recommended for applications with tight mechanical constraints.
Q: What inventory levels are available for each substitute part?
A: TE Connectivity 2-5747709-0: 1537 units. HARTING 09664156503: 1060 units. HARTING 09664516513: 989 units. HARTING 09664517513: 1009 units. HARTING 09664556513: 1128 units. HARTING 09664557513: 702 units. NorComp 172-037-212R001: 1158 units. NorComp 172-037-212R011: 840 units. NorComp 172-037-212R911: 1030 units. NorComp 191-037-213L001: 1105 units. All parts are listed as new original in stock.
