DCPS37S365TLF D-Sub 37 Position Receptacle Connector Equivalent & Substitute Parts
Part Overview
The DCPS37S365TLF is a 37 position D-Sub receptacle connector manufactured by Amphenol ICC (FCI) in the DP series. This through-hole solder termination connector features female sockets with a 4 (DC, C) shell size layout and is designed for signal applications. The part is currently active in production with 1102 units in stock. Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design specifications allow for compatible alternatives from different manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation
Substitution eligibility for the DCPS37S365TLF is determined by strict alignment of the following critical parameters:
Primary Compatibility Criteria:
- Connector type: Receptacle, Female Sockets
- Number of positions: 37
- Number of rows: 2
- Shell size and layout: 4 (DC, C)
- Mounting type: Through Hole
- Termination method: Solder
- Material flammability rating: UL94 V-0
Secondary Compatibility Considerations:
- Contact finish and thickness specifications
- Current and voltage ratings
- Operating temperature range
- Shell material and finish composition
- Dielectric material properties
- RoHS and REACH compliance status
Substitute parts are grouped into two categories: direct equivalents with identical or superior electrical specifications, and functional alternatives with acceptable parameter variations within engineering tolerances. All listed substitutes maintain the core 37-position D-Sub receptacle configuration with through-hole solder termination and meet or exceed the primary part's performance envelope.

Engineering Selection Recommendations
Direct Equivalents (Highest Compatibility):
The HARTING 09664516513 and 09664517513 maintain full compatibility with the DCPS37S365TLF across all critical parameters including connector type, position count, shell size, mounting configuration, and operating temperature range. Both parts are ROHS3 compliant and carry active product status. The primary distinction between these two HARTING options is packaging format: 09664516513 is supplied in tray packaging, while 09664517513 is supplied in bulk. Both feature board lock functionality and female screwlock mating side flanges.
The TE Connectivity 1-5747301-4 and 2-5747709-0 from the AMPLIMITE HD-20 series provide functional equivalence with identical shell size, position count, and solder termination. Both are RoHS compliant and active products. The 2-5747709-0 includes board lock features and housing shell flange with 4-40 threading. Operating temperature range is -55°C to 105°C, which is 20°C lower than the primary part's maximum specification.
Functional Alternatives (Acceptable Variations):
The NorComp 172-E series connectors (172-E37-213R001, 172-E37-213R011, 172-E37-213R031, 172-E37-213R911) are panel mount through-hole configurations with identical position count and shell size. These parts feature nickel-plated steel shells and machined brass contacts with flash gold plating. Current rating is 5A per contact, which is lower than the primary part's 7.5A specification. Operating temperature range is -50°C to 100°C. All NorComp 172-E variants are ROHS3 compliant and carry active product status. These parts are suitable for applications where panel mounting capability is required and current requirements do not exceed 5A per contact.
Compliance and Certification:
All listed substitute parts maintain UL94 V-0 material flammability rating and are RoHS compliant. REACH status varies: HARTING and NorComp parts are REACH Unaffected, while TE Connectivity 2-5747709-0 is REACH Affected. Selection should account for end-use regulatory requirements in specific geographic markets.
Frequently Asked Questions (FAQ)
Q: Can HARTING 09664516513 be used as a direct replacement for DCPS37S365TLF?
A: Yes. Both connectors share identical core specifications: 37-position receptacle, female sockets, 4 (DC, C) shell size, through-hole solder termination, and -55°C to 125°C operating temperature. The primary difference is shell finish (HARTING uses steel without specified finish versus Amphenol's tin-plated steel). Both are RoHS compliant and carry active product status. Packaging differs: HARTING 09664516513 is supplied in tray format.
Q: What is the difference between HARTING 09664516513 and 09664517513?
A: These parts are electrically and mechanically identical. The sole distinction is packaging: 09664516513 is supplied in tray packaging, while 09664517513 is supplied in bulk packaging. Both feature board lock functionality and female screwlock mating side flanges (4-40).
Q: Can TE Connectivity 1-5747301-4 replace DCPS37S365TLF in all applications?
A: Functional replacement is possible with design review. The TE part maintains identical connector type, position count, shell size, and solder termination. However, operating temperature maximum is 105°C versus the primary part's 125°C, and current rating is 6A versus 7.5A. Voltage rating is 125V versus 1000V. Applications operating above 105°C or requiring 7.5A per contact or 1000V rating require the primary part or higher-rated alternatives.
Q: What are the key differences between through-hole and panel mount D-Sub 37 connectors?
A: Through-hole connectors (DCPS37S365TLF, HARTING 09664516513, TE Connectivity 1-5747301-4 and 2-5747709-0) mount directly to PCB pads for vertical or right-angle board insertion. Panel mount connectors (NorComp 172-E series) include flange features for mounting to enclosure panels or bulkheads. Panel mount variants require additional mechanical support and are not interchangeable with through-hole designs without PCB redesign.
Q: Are NorComp 172-E37 connectors suitable for high-current applications?
A: NorComp 172-E37 connectors are rated for 5A per contact, which is lower than DCPS37S365TLF (7.5A) and most other listed substitutes (6A to 6.5A). These parts are appropriate for signal-level applications and moderate current requirements. Applications requiring 7.5A per contact must use DCPS37S365TLF or equivalent high-current rated alternatives.
Q: What packaging options are available for 37-position D-Sub receptacles?
A: Listed substitutes are supplied in three packaging formats: tray (DCPS37S365TLF, HARTING 09664516513, NorComp 172-E series), bulk (HARTING 09664517513), and tube (TE Connectivity 1-5747301-4 and 2-5747709-0). Packaging selection depends on inventory management requirements, handling procedures, and quantity per order. Electrical and mechanical specifications remain identical across packaging variants for the same part number.
Q: Do all substitute parts meet RoHS compliance requirements?
A: Yes. All listed substitute parts carry either RoHS Compliant or ROHS3 Compliant status. REACH compliance status varies: HARTING 09664516513, 09664517513, and all NorComp 172-E variants are REACH Unaffected. TE Connectivity 2-5747709-0 is REACH Affected. Design specifications and end-use market regulations should determine REACH compliance requirements.
