Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DEML09S500N are qualified based on the following critical parameters that determine functional compatibility:

Core Matching Criteria:

• Connector type: D-Sub receptacle, female sockets
• Position count: 9 positions
• Shell size and layout: 1 (DE, E)
• Mounting configuration: Through hole, right angle
• Termination method: Solder
• Flammability rating: UL94 V-0

Allowable Parameter Variations: Substitute parts may differ in the following areas while maintaining functional compatibility:

• Current rating: Substitutes rated at 6.5A are acceptable for applications not requiring the full 7.5A capacity
• Voltage rating: Substitutes rated at 100V or unspecified voltage are acceptable for applications operating below 300V
• Operating temperature range: Substitutes with -55°C ~ 125°C range are acceptable for applications not requiring the full 155°C upper limit
• Contact finish: Gold or unspecified finishes are acceptable alternatives to the original specification
• Shell finish: Steel with various plating options (tin, unspecified) are acceptable
• Contact form: Both machined and stamped contact forms are acceptable
• Dielectric material: Thermoplastic, PCT, or PBT variants are acceptable
• Contact material: Brass, copper alloy, or phosphor bronze are acceptable
• Flange feature: Variations in mounting flange design (M3, 4-40, unthreaded) are acceptable

Substitutes that meet these criteria are listed below.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Highest Compatibility): The 09641147232 from HARTING maintains the closest electrical specifications to the DEML09S500N, matching the 7.5A current rating and providing superior voltage rating at 100V. This part is actively produced and ROHS3 compliant, making it suitable for new designs requiring regulatory compliance. The machined contact form and board lock feature provide enhanced reliability.

Secondary Substitutes (Reduced Current Rating): Parts 09661126603, 09661526613, 09661527613, and 09661536613 from HARTING are qualified substitutes for applications where the current requirement does not exceed 6.5A per contact. These parts are ROHS3 compliant and actively produced. The 09661527613 offers the highest inventory availability at 2715 units. All four parts feature board lock functionality and stamped contact construction.

Alternative Substitute (Reduced Current and Voltage): The L77SDE09SA4CH from Amphenol ICC (Commercial Products) is a RoHS compliant alternative suitable for applications with current requirements not exceeding 3A and voltage not exceeding 250V. This part features a reduced backset spacing of 0.318" (8.08mm) compared to the original 0.406" (10.30mm), which may affect PCB layout compatibility. The gold-plated contact finish and board lock feature are included.

Compliance Considerations: The original DEML09S500N is RoHS non-compliant. All substitute parts listed are either ROHS3 compliant or RoHS compliant, making them suitable for applications subject to RoHS regulations. The HARTING substitutes provide REACH unaffected status, offering additional regulatory assurance.

Frequently Asked Questions (FAQ)

Q: Can the 09641147232 be used as a direct replacement for the DEML09S500N? A: The 09641147232 is functionally compatible for applications operating at or below 100V and 7.5A per contact. The primary difference is the reduced voltage rating (100V vs. 300V). If your application requires the full 300V rating, this substitute is not appropriate.

Q: What is the significance of the backset spacing difference in the L77SDE09SA4CH? A: The L77SDE09SA4CH has a backset spacing of 0.318" (8.08mm) compared to the DEML09S500N at 0.406" (10.30mm). This 0.088" difference affects the distance between the connector mounting plane and the contact insertion point. PCB layout and mating connector positioning must be verified before substitution.

Q: Are the HARTING substitutes with 6.5A rating suitable for my 7.5A application? A: The 6.5A rated parts (09661126603, 09661526613, 09661527613, 09661536613) are not suitable if your application requires the full 7.5A per contact capacity. Use only the 09641147232 if 7.5A capacity is mandatory.

Q: What is the difference between bulk and tray packaging? A: Bulk packaging typically contains loose components, while tray packaging provides organized component placement for automated assembly. The electrical and mechanical specifications are identical; packaging choice depends on assembly process requirements and handling preferences.

Q: Can I use the L77SDE09SA4CH in a high-current application? A: No. The L77SDE09SA4CH is rated for only 3A per contact, making it unsuitable for applications requiring 6.5A or 7.5A. This part is qualified only for low-current signal applications.

Q: Are all substitute parts actively produced? A: Yes. All substitute parts listed maintain active product status with current inventory availability, ensuring reliable sourcing for new designs and production requirements.

Q: What is the impact of switching from machined to stamped contacts? A: Both contact forms meet the UL94 V-0 flammability requirement and are functionally compatible. Stamped contacts (used in most HARTING substitutes) provide cost efficiency, while machined contacts (DEML09S500N and 09641147232) offer enhanced durability in high-cycle mating applications.
