DEMM9SMA101 D-Sub 9 Position Receptacle Connector

Part Overview

The DEMM9SMA101 is a 9 position D-Sub receptacle connector manufactured by ITT Cannon, LLC, featuring female sockets with panel mount, through-hole solder termination. This connector is classified as a D-shaped connector (Shell Size 1, DE/E layout) with signal contact capability and UL94 V-0 flammability rating. The part is currently active in production with 748 units in stock.

Equivalent and substitute parts are necessary when the original DEMM9SMA101 becomes unavailable, when alternative termination methods are required (press-fit versus solder), when different mounting configurations are needed, or when compliance requirements (RoHS status) differ between applications.

• Number of rows must be 2
• Shell size and layout must be 1 (DE, E)
• Contact type must be Signal or Signal and Power

Secondary Compatibility Criteria:

• Termination method (Solder, Press-Fit, or Solder Paste)
• Mounting configuration (Panel Mount, Through Hole, or Board Side)
• Shell material and finish composition
• Contact finish and thickness specifications
• Operating temperature range capability
• Current rating per contact
• Flammability rating (UL94 V-0 preferred)

Compliance Considerations:

• RoHS compliance status (compliant or non-compliant)
• REACH status (affected, unaffected, or vendor undefined)

The substitute parts listed below meet the primary compatibility criteria. Variations in termination method, mounting style, shell finish, and compliance status are noted to enable selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

For RoHS Compliant Applications: Select from 5747091-2, 5786143-1, 628-009-220-041, 628-009-220-047, 628-009-220-048, D09S24A6RV22LF, or FCE17-E09SE-A50. These parts meet ROHS3 or RoHS Compliant status and are suitable for applications requiring environmental compliance.

For Solder Termination Compatibility: The DEMM9SMA101 uses solder termination. Direct solder-to-solder substitutes include 628-009-220-041, 628-009-220-047, 628-009-220-048, D09S24A6RV22LF, FCE17-E09SE-A50, M24308/23-1F, and M24308/23-7F. Press-fit alternatives (5747091-2, 5786143-1) require different PCB pad design and assembly processes.

For Extended Temperature Range: The DEMM9SMA101 operates from -55°C to 150°C. M24308/23-1F and M24308/23-7F support -55°C to 125°C. Mercury 628 series parts support -55°C to 85°C. TE Connectivity press-fit parts support -55°C to 105°C. Amphenol FCE17 supports -40°C to 85°C.

For Current Capacity: The DEMM9SMA101 is rated at 7.5A total. Mercury 628 series parts are rated at 3A per contact. Amphenol D09S24A6RV22LF and FCE17-E09SE-A50 are rated at 5A per contact. TE Connectivity military parts (M24308/23-1F, M24308/23-7F) are rated at 5A per contact.

For Military or Aerospace Applications: M24308/23-1F and M24308/23-7F comply with MIL-DTL-24308 specification and are manufactured by TE Connectivity Aerospace, Defense and Marine. These parts maintain RoHS non-compliant status consistent with the original DEMM9SMA101.

For Active Production and Inventory Availability: All listed substitute parts are active in production. Highest inventory levels are available for M24308/23-7F (3458 units), 5747091-2 (3350 units), and 628-009-220-047 (1567 units).

Frequently Asked Questions (FAQ)

Q: Can I substitute a press-fit connector (5747091-2, 5786143-1) for the solder-terminated DEMM9SMA101?

A: Press-fit connectors require different PCB pad design, hole sizing, and assembly equipment compared to solder-terminated connectors. Direct mechanical substitution is not possible without PCB redesign. Press-fit termination eliminates solder reflow but requires press-fit tooling and different manufacturing processes.

Q: What is the difference between the Mercury 628 series parts (628-009-220-041, 628-009-220-047, 628-009-220-048)?

A: All three Mercury parts share identical electrical and mechanical specifications. The primary differences are packaging (Tray for 628-009-220-041 and 628-009-220-047; Bulk for 628-009-220-048) and features (628-009-220-047 includes Board Lock feature; 628-009-220-041 and 628-009-220-048 include Shielded feature). Selection depends on assembly requirements and feature necessity.

Q: Why does the DEMM9SMA101 have a higher current rating (7.5A) than most substitutes?

A: The DEMM9SMA101 is rated at 7.5A total connector current. Mercury 628 series parts specify 3A per contact, and Amphenol/TE Connectivity parts specify 5A per contact. These per-contact ratings differ from total connector ratings. Verify application current requirements against the specific rating methodology of the selected substitute.

Q: Are M24308/23-1F and M24308/23-7F interchangeable?

A: M24308/23-1F and M24308/23-7F are both MIL-DTL-24308 compliant 9 position D-Sub receptacles with identical electrical and mechanical specifications. Both support -55°C to 125°C operating temperature and 5A current rating. Selection between these parts depends on availability and procurement requirements.

Q: Can I use an RoHS compliant substitute in a non-RoHS application?

A: Yes. RoHS compliant parts can be used in applications that do not require RoHS compliance. However, RoHS non-compliant parts (DEMM9SMA101, M24308/23-1F, M24308/23-7F) cannot be used in applications requiring RoHS compliance.

Q: What is the difference between Solder Paste termination (D09S24A6RV22LF) and standard Solder termination?

A: Solder Paste termination is designed for automated surface mount assembly processes using solder paste and reflow ovens. Standard Solder termination is designed for wave soldering or manual soldering processes. D09S24A6RV22LF includes Board Guide and Pick and Place Cap features for automated assembly compatibility.

Q: Which substitute offers the best thermal performance?

A: M24308/23-1F and M24308/23-7F support the widest operating temperature range (-55°C to 125°C) among substitutes. The DEMM9SMA101 itself supports the highest maximum temperature (-55°C to 150°C). For applications requiring extended high-temperature operation beyond 125°C, the original DEMM9SMA101 is the only option listed.
