DEM09S500C 9-Position D-Sub Receptacle Equivalent & Substitute Parts
Part Overview
The DEM09S500C is a 9-position D-Sub receptacle connector manufactured by Amphenol ICC (FCI) in the DM HE501 series. This right-angle, through-hole solder connector features female sockets with a 1 (DE, E) shell size and is designed for signal applications requiring 7.5A per contact at 300V. The part is currently active in production with 1,037 units in stock.
Equivalent and substitute parts are necessary when the original DEM09S500C becomes unavailable, when design requirements shift toward RoHS compliance, or when alternative manufacturers' components offer improved availability or performance characteristics within acceptable electrical and mechanical parameters.

Substitute Part Grouping Explanation
Substitution of the DEM09S500C is determined by strict adherence to the following electrical and mechanical parameters:
Critical Compatibility Parameters:
- Connector type: Receptacle, Female Sockets
- Number of positions: 9
- Shell size and layout: 1 (DE, E)
- Mounting configuration: Through Hole, Right Angle
- Termination method: Solder
- Flammability rating: UL94 V-0
Electrical Performance Parameters:
- Current rating must equal or exceed 7.5A per contact
- Voltage rating must equal or exceed 300V
- Operating temperature range must encompass -55°C to 125°C
Material and Finish Parameters:
- Contact material: Phosphor Bronze
- Contact finish: Gold
- Shell material: Steel
Substitute parts are grouped into two categories based on these criteria:
Category A - Direct Electrical Equivalents (Current ≥ 7.5A, Voltage ≥ 300V): No substitute parts meet both the 7.5A current and 300V voltage requirements simultaneously.
Category B - Functional Equivalents (Current 5-6A, Voltage 125V): Parts with reduced current and voltage ratings but identical connector geometry, mounting, and termination. These include TE Connectivity AMPLIMITE HD-20 series parts (5788797-2, 5788803-1, 6-747844-8, 6-788796-7, 747844-2, 747844-3, 747844-5, 747844-6) and NorComp 182-009-213R531.
Category C - Partial Compatibility (Reduced Current 3A, Voltage 350V): Hirose RDED-9S-LN(55) with different flange feature and lower current rating.

Engineering Selection Recommendations
For applications requiring full electrical equivalence (7.5A, 300V): No substitute parts from the provided list meet both current and voltage specifications. The DEM09S500C remains the only option within this parameter set.
For applications tolerating reduced current (5-6A) and voltage (125V): TE Connectivity AMPLIMITE HD-20 series parts (5788797-2, 5788803-1, 6-747844-8, 6-788796-7, 747844-2, 747844-3, 747844-5, 747844-6) provide direct mechanical and functional substitution with identical connector geometry and mounting. These parts maintain phosphor bronze contacts with gold finish and UL94 V-0 flammability rating.
For RoHS3 compliance: Select 5788803-1, 6-788796-7, or 182-009-213R531. These parts carry ROHS3 Compliant certification. Note that 182-009-213R531 operates to 105°C maximum and carries a 5A current rating.
For applications with extended temperature requirements to 125°C: The DEM09S500C and all TE Connectivity AMPLIMITE HD-20 variants support -55°C to 105°C. The DEM09S500C alone extends to 125°C.
For applications with 350V voltage requirement: RDED-9S-LN(55) from Hirose provides 350V rating but carries Last Time Buy status, 3A current rating, and reduced operating temperature to 85°C maximum. This part is not recommended for new designs.
For inventory availability: TE Connectivity 747844-3 offers the highest stock level (2,700 units) among AMPLIMITE HD-20 variants. NorComp 182-009-213R531 provides 7,246 units in stock.
Frequently Asked Questions (FAQ)
Q: Can DEM09S500C be directly replaced with any part from the substitute list?
A: No direct replacement exists that maintains all electrical specifications. The DEM09S500C operates at 7.5A and 300V. All TE Connectivity and NorComp substitutes operate at reduced ratings (5-6A, 125V). Selection depends on whether your application can tolerate these reductions.
Q: What is the primary difference between DEM09S500C and the TE Connectivity AMPLIMITE HD-20 series?
A: The primary differences are current rating (7.5A vs. 6A), voltage rating (300V vs. 125V), maximum operating temperature (125°C vs. 105°C), and shell finish (yellow cadmium plated vs. tin plated). Connector geometry, mounting type, termination method, and contact materials remain identical.
Q: Are the TE Connectivity 747844 variants interchangeable with each other?
A: The 747844 variants (747844-2, 747844-3, 747844-5, 747844-6) share identical electrical specifications (6A, 125V, -55°C to 105°C) and core mechanical design. Differences exist in flange features (Housing/Shell unthreaded vs. 4-40 threaded vs. Mating Side Female Screwlock) and contact finish thickness (Flash vs. 30.0µin). Selection depends on PCB mounting requirements and finish specifications.
Q: Why is RDED-9S-LN(55) marked as Last Time Buy?
A: Last Time Buy status indicates the manufacturer has discontinued this product line. While 844 units remain in stock, this part should not be selected for new designs or long-term production requirements.
Q: Does NorComp 182-009-213R531 provide full compatibility?
A: 182-009-213R531 maintains identical connector geometry and mounting but differs in current rating (5A vs. 7.5A), lacks a specified voltage rating, operates to 105°C maximum, and features nickel-plated steel shell instead of cadmium-plated. It is suitable for applications with reduced electrical demands.
Q: What compliance considerations apply to substitute selection?
A: The DEM09S500C is RoHS non-compliant due to yellow cadmium plating. For RoHS3 compliance, select 5788803-1, 6-788796-7, or 182-009-213R531. All parts carry REACH Unaffected or REACH Affected status as specified. ECCN classification remains EAR99 across all parts.
Q: Can operating temperature differences affect substitution decisions?
A: Yes. The DEM09S500C operates to 125°C. All TE Connectivity and NorComp substitutes operate to 105°C maximum. RDED-9S-LN(55) operates to 85°C maximum. Applications requiring sustained operation above 105°C require the original DEM09S500C.
