Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEMM9PHA101 is determined by the following critical parameters:

• Connector Style & Type: Must be D-Sub plug with male pins
• Position Count & Layout: Must be 9-position with 2-row configuration and 1 (DE, E) shell size
• Mounting & Termination: Must support panel mount through-hole with solder termination
• Electrical Performance: Current rating and operating temperature range must meet or exceed application requirements
• Contact Configuration: Signal contact type with gold finish preferred for signal integrity
• Compliance: RoHS status and material flammability rating determine suitability for specific applications

The substitute parts listed below meet the core mechanical and electrical compatibility criteria. Variations in current rating, operating temperature range, shell finish, and compliance certifications are noted to enable informed selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Mechanical & Electrical Compatibility (Panel Mount, Through Hole)

The 172-009-112R911 from NorComp Inc. provides mechanical compatibility with panel mount through-hole configuration. However, this part is marked Obsolete and carries a reduced current rating of 5A compared to the DEMM9PHA101's 7.5A specification. The operating temperature range is also limited to -50°C ~ 100°C. This part is suitable only for legacy system maintenance where availability is confirmed.

Active Status Alternatives with Reduced Current Rating

The Mercury United Electronics 627-009-220-046, 627-009-220-047, and 627-009-220-048 are all Active status parts with ROHS3 compliance. These connectors feature board-side mounting with 4-40 screwlock configuration rather than panel mount. Current rating is reduced to 3A per contact, and operating temperature is limited to -55°C ~ 85°C. These parts are suitable for applications where the reduced current and temperature specifications are acceptable and RoHS compliance is required.

The 627-009-222-042 variant uses solder cup termination and free-hanging (in-line) mounting, making it incompatible with panel mount applications.

High-Temperature Alternative

The L717SDEH09POL2RM8 from Amphenol ICC (Commercial Products) maintains the -55°C ~ 125°C operating range and is RoHS Compliant with Active status. Current rating is 3A. This part supports through-hole mounting with board-side 4-40 screwlock configuration. The stamped contact form and thermoplastic glass-filled dielectric differ from the DEMM9PHA101's machined contacts and PCT dielectric.

Military-Grade Alternative

The M24308/24-7F from TE Connectivity Aerospace, Defense and Marine is a military-specification connector (MIL-DTL-24308) with Active status. It maintains the -55°C ~ 125°C operating range and 5A current rating. The connector features housing/shell unthreaded configuration matching the DEMM9PHA101. This part is RoHS non-compliant and REACH Affected, making it suitable for military and aerospace applications where compliance requirements differ from commercial standards.

Selection Criteria Summary

• For RoHS-compliant applications with reduced current requirements: Select Mercury United Electronics 627-009 series or Amphenol ICC L717SDEH09POL2RM8
• For high-temperature applications with military specifications: Select TE Connectivity M24308/24-7F
• For legacy system maintenance: Confirm availability of NorComp 172-009-112R911 before selection
• For applications requiring full 7.5A current rating and 150°C upper temperature limit: Retain DEMM9PHA101 as primary specification

Frequently Asked Questions (FAQ)

Q: Can the 627-009-220-046 directly replace the DEMM9PHA101 in a panel mount application?

A: No. The 627-009-220-046 features board-side mounting with 4-40 screwlock configuration, not panel mount through-hole. Physical installation would require redesign of the mounting interface. Additionally, the current rating is reduced from 7.5A to 3A per contact.

Q: What is the primary difference between 627-009-220-046, 627-009-220-047, and 627-009-220-048?

A: All three parts share identical electrical and mechanical specifications. The primary difference is packaging: 627-009-220-046 is packaged in Tube, 627-009-220-047 in Tray, and 627-009-220-048 in Tray with higher inventory (2058 units). Features also differ slightly: 627-009-220-046 and 627-009-220-047 include Board Lock and Grounding Indents, while 627-009-220-048 includes only Shielded feature.

Q: Is the L717SDEH09POL2RM8 suitable for applications requiring 150°C operation?

A: No. The L717SDEH09POL2RM8 is rated for -55°C ~ 125°C maximum operating temperature, which is 25°C below the DEMM9PHA101 specification of -55°C ~ 150°C. Applications requiring sustained operation above 125°C must retain the DEMM9PHA101 or equivalent high-temperature rated connector.

Q: Why is the M24308/24-7F marked RoHS non-compliant?

A: The M24308/24-7F is a military-specification connector (MIL-DTL-24308) manufactured to military standards that predate RoHS requirements. Military and aerospace applications often operate under different compliance frameworks than commercial products. Verify compliance requirements for your specific application before selection.

Q: Can I use the 627-009-222-042 as a substitute for panel mount applications?

A: No. The 627-009-222-042 features free-hanging (in-line) mounting with solder cup termination, not panel mount through-hole with solder termination. This part is designed for wire harness applications, not panel-mounted installations.

Q: What is the significance of contact finish thickness specification?

A: The DEMM9PHA101 specifies 50.0µin (1.27µm) gold contact finish thickness, while substitute parts specify Flash thickness. Flash plating provides minimal gold coverage for corrosion protection without the thickness of standard plating. Applications requiring enhanced contact durability or specific contact resistance specifications should verify flash thickness acceptability.

Q: Are all substitute parts compatible with the same mating connectors as the DEMM9PHA101?

A: All listed substitute parts maintain the 1 (DE, E) shell size and 9-position configuration, ensuring mechanical compatibility with standard D-Sub 9-position receptacles. However, verify specific mating connector specifications for your application, as some variants include features such as screwlock or board lock that may affect mating interface requirements.
