DEM09P500C D-Sub Plug 9-Position Right Angle Solder Connector

Part Overview

The DEM09P500C is a 9-position D-Sub plug connector manufactured by Amphenol ICC (FCI) in the DM HE501 series. This through-hole, right-angle solder connector features male pins with a DE/E shell size (1 position layout) and is designed for signal applications requiring 7.5A per contact at 300V. The connector is actively produced and maintains 928 units in current inventory. Equivalent and substitute parts are identified when original stock becomes unavailable, when design requirements shift toward alternative compliance standards (such as RoHS3), or when specific flange features or contact finishes better suit application constraints.

Engineering Selection Recommendations

For RoHS3 Compliance Requirements: Select from HARTING (09681635812, 09681635813, 09681637813), NorComp Inc. (182-009-113R161), TE Connectivity (5747250-3), or Amphenol ICC Commercial Products (6E17C-009P-AJ-121). These parts carry explicit ROHS3 Compliant or RoHS Compliant designations and are suitable for applications subject to modern environmental regulations.

For Legacy or Non-Regulated Applications: The original DEM09P500C (RoHS non-compliant) remains available with 928 units in stock. TE Connectivity 7-747840-1 is also RoHS non-compliant and maintains 1,376 units in inventory.

For Maximum Current Capacity: The DEM09P500C provides the highest current rating at 7.5A per contact. All substitute parts are rated at 5A to 6.5A per contact. If 7.5A per contact is a hard requirement, the original part is the only option.

For Extended Temperature Range: The DEM09P500C operates from -55°C to 125°C. NorComp Inc. (182-009-113R161), TE Connectivity (5747250-2, 5747250-3, 7-747840-1, 747250-6, 747840-5), and Amphenol ICC Commercial Products (6E17C-009P-AJ-121) are limited to -55°C to 105°C. HARTING parts (09681635812, 09681635813, 09681637813) match the full -55°C to 125°C range.

For Flange Configuration: Unthreaded housing/shell options: DEM09P500C, 182-009-113R161, 5747250-2. Threaded 4-40 housing options: 09681635812, 5747250-3, 6E17C-009P-AJ-121. Female screwlock mating side options: 09681635813, 09681637813, 7-747840-1, 747250-6, 747840-5.

For Inventory Availability: Highest stock levels: 6E17C-009P-AJ-121 (5,570 units), 182-009-113R161 (1,816 units), 5747250-3 (1,279 units), 7-747840-1 (1,376 units).

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a lower current rating than the DEM09P500C? A: Substitutes rated at 5A to 6.5A per contact are acceptable only if your circuit design does not require the full 7.5A per contact capacity of the original part. Verify actual current draw in your application before selecting a lower-rated substitute.

Q: What is the difference between unthreaded and 4-40 threaded flanges? A: Unthreaded housing/shell flanges provide basic mechanical retention. 4-40 threaded flanges allow screw-based fastening for enhanced mechanical stability. Female screwlock variants on the mating side provide additional strain relief. Selection depends on your PCB mounting and mechanical assembly requirements.

Q: Are HARTING parts fully compatible with the DEM09P500C footprint? A: HARTING parts (09681635812, 09681635813, 09681637813) match all critical parameters: 9-position, 2-row, DE/E shell size, through-hole right-angle solder termination, and UL94 V-0 rating. However, backset spacing differs (0.318" vs. 0.406"), which may affect PCB layout. Verify mechanical fit before design release.

Q: Which substitute offers the best RoHS3 compliance with maximum current capacity? A: TE Connectivity 5747250-3 provides ROHS3 Compliant status with 6A per contact rating, 125V voltage rating, and 4-40 threaded housing. This represents the highest current capacity among RoHS3-compliant options.

Q: Can I substitute a part with a different shell material finish? A: Yes. Yellow Cadmium Plated (original), Nickel Plated, and Tin Plated finishes are all acceptable substitutes provided the connector maintains the same electrical and mechanical specifications. Material finish selection depends on corrosion resistance requirements and environmental exposure in your application.

Q: What does "Contact Finish Thickness: Flash" mean? A: Flash plating indicates a very thin gold or gold-palladium coating applied to the contact surface. This is acceptable for signal-level applications and provides corrosion protection while maintaining cost efficiency compared to thicker plating specifications.

Q: Are TE Connectivity AMPLIMITE HD-20 series parts direct replacements? A: TE Connectivity AMPLIMITE HD-20 series parts (5747250-2, 5747250-3, 7-747840-1, 747250-6, 747840-5) are functionally compatible as 9-position D-Sub plugs with right-angle solder termination. However, operating temperature is limited to -55°C to 105°C (versus -55°C to 125°C for the original), and current ratings are 6A (versus 7.5A). Confirm these differences do not conflict with your design specifications.

Q: What is the significance of "Moisture Sensitivity Level 1 (Unlimited)"? A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture-control storage or handling. This applies to most D-Sub connectors and simplifies inventory management and logistics.
