DEM09P500MN D-Sub 9-Position Right Angle Solder Plug Connector

Part Overview

The DEM09P500MN is a 9-position D-Sub plug connector with right-angle through-hole solder termination, manufactured by Amphenol ICC (FCI) in the DM HE508 series. This connector is classified as obsolete, which necessitates identification of active substitute components that maintain electrical and mechanical compatibility for applications requiring D-Sub connectivity in legacy or ongoing production environments.

Termination method: Solder

Acceptable Variation Parameters:

Current rating: Substitute must meet or exceed 6.0A minimum per contact
Voltage rating: Substitute must meet or exceed 125V minimum
Operating temperature range: Substitute must support -55°C minimum and 105°C minimum upper limit
Shell material finish: Steel with various plating options (cadmium, tin, or unplated)

RoHS compliance: Active substitutes may be RoHS3 compliant

Non-Substitutable Parameters:

15-position variants (09652666815, 09652666816) are excluded due to position count mismatch

Engineering Selection Recommendations

Tier 1 Substitutes (Highest Compatibility): DEM09P500M and 09661627817 maintain the closest electrical specifications to the original DEM09P500MN. DEM09P500M is an active Amphenol ICC variant with identical current and voltage ratings. 09661627817 (HARTING) provides equivalent 7.5A current capacity and is RoHS3 compliant for new designs.

Tier 2 Substitutes (Acceptable for Most Applications): 09651626817 and 09651627817 (HARTING) meet the 9-position, right-angle, through-hole solder configuration with 6.5A current capacity and RoHS3 compliance. These are suitable where the original 7.5A rating is not critical.

Tier 3 Substitutes (Limited Application): 5745434-8 (TE Connectivity) provides active production status and RoHS compliance but operates at reduced current (6.0A) and voltage (125V) ratings. FCE17E09PB440 (Amphenol ICC) and L717SDE09P1ACH3F (Amphenol ICC) have further reduced current ratings (5.0A and 3.0A respectively) and narrower operating temperature ranges, limiting their use to lower-power applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 15-position D-Sub connector as a substitute for the 9-position DEM09P500MN? A: No. The 15-position variants (09652666815, 09652666816) have different shell sizes and layouts (2 DA, A) and are not mechanically or electrically compatible with 9-position receptacles.

Q: What is the primary reason the DEM09P500MN is obsolete? A: The DEM09P500MN is classified as obsolete by the manufacturer. Active substitutes from Amphenol ICC (DEM09P500M) and other manufacturers (HARTING, TE Connectivity) provide equivalent or superior functionality with current production support.

Q: Are HARTING 09651626817 and 09651627817 interchangeable? A: Both are 9-position D-Sub plugs with identical electrical and mechanical specifications. They are functionally interchangeable for applications requiring 6.5A current capacity.

Q: Does the DEM09P500M have the same temperature rating as the original DEM09P500MN? A: No. The DEM09P500M operates from -55°C to 125°C, while the original operates to 155°C. Applications requiring operation above 125°C must use the original part or equivalent high-temperature variants.

Q: Which substitute offers the best RoHS compliance for new product designs? A: HARTING parts (09651626817, 09651627817, 09661627817) and TE Connectivity 5745434-8 are RoHS3 compliant. Amphenol ICC DEM09P500M remains RoHS non-compliant.

Q: What is the difference between cadmium-plated and tin-plated shell finishes? A: Cadmium plating (original DEM09P500MN and DEM09P500M) provides superior corrosion resistance but is restricted under RoHS regulations. Tin plating (5745434-8, FCE17E09PB440, L717SDE09P1ACH3F) is RoHS-compliant but offers reduced corrosion protection in harsh environments.

Q: Can I substitute a lower current-rated connector if my application only requires 3A? A: Yes, provided all other parameters match. L717SDE09P1ACH3F is rated for 3.0A and maintains the 9-position, right-angle, solder configuration. However, verify the operating temperature range (-40°C to 85°C) meets your application requirements.
