DEMD9SJF225 D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The DEMD9SJF225 is a 9-position D-Sub receptacle connector manufactured by ITT Cannon, LLC, designed for panel mount, through-hole, right-angle solder applications. This connector features female sockets with a stainless steel shell and gold-plated contacts, rated for 7.5A continuous current operation across an extended temperature range of -55°C to 125°C. The connector maintains active product status and full RoHS compliance, making it suitable for industrial and commercial electronic assemblies requiring reliable signal transmission in D-Sub form factor applications.

Equivalent substitute parts are identified when component availability, lead time, or procurement constraints necessitate alternative sourcing while maintaining functional and electrical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEMD9SJF225 is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Female Sockets (9-position)
• Shell Size and Layout: 1 (DE, E) form factor
• Mounting Configuration: Through Hole, Right Angle orientation
• Termination Method: Solder
• Flange Feature: Mating Side, Female Screwlock (4-40)

Performance Parameters (Substitute Must Meet or Exceed):

• Current Rating: Minimum 7.5A
• Operating Temperature Range: Minimum -55°C to 125°C coverage
• Contact Finish: Gold plating for signal integrity

Compliance Parameters:

• RoHS Status: Substitute must maintain RoHS compliance or higher regulatory standard
• Material Flammability: UL94 V-0 rating required

The substitute part 173-E09-213R141 (NorComp Inc.) satisfies all mandatory matching parameters and maintains equivalent functional performance within the specified electrical and mechanical constraints. Differences in shell material finish (nickel-plated steel versus stainless steel) and current rating (5A versus 7.5A) represent trade-offs documented in the parameter comparison table below.

Engineering Selection Recommendations

Primary Part Selection (DEMD9SJF225): Select the DEMD9SJF225 when applications require the full 7.5A current rating or when stainless steel shell material is specified for enhanced corrosion resistance in harsh environments. This part maintains active manufacturing status with 1078 units in current inventory, ensuring reliable procurement lead times. RoHS compliance and UL94 V-0 flammability rating satisfy standard industrial regulatory requirements.

Substitute Part Selection (173-E09-213R141): The 173-E09-213R141 serves as a functional equivalent when current requirements do not exceed 5A and nickel-plated steel shell material is acceptable. This substitute maintains identical connector geometry, pin configuration, and mating interface specifications. ROHS3 compliance exceeds the primary part's RoHS standard, providing enhanced regulatory alignment for applications subject to stricter environmental directives. Active product status and 777 units in inventory support consistent availability.

Selection Criteria:

• If application current draw is ≤5A: Either part is acceptable; select based on availability and cost
• If application current draw is >5A and ≤7.5A: Primary part (DEMD9SJF225) is required
• If corrosion resistance in marine or chemical environments is critical: Primary part (stainless steel) is preferred
• If ROHS3 compliance is mandated: Substitute part (173-E09-213R141) is required

Both parts are suitable for direct substitution in applications where the specified current and environmental parameters align with design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 173-E09-213R141 substitute for DEMD9SJF225 in all applications?

A: The 173-E09-213R141 is functionally equivalent for applications where continuous current does not exceed 5A. If your circuit requires current between 5A and 7.5A, the primary part (DEMD9SJF225) must be used. Both parts share identical connector geometry, pin count, and mating interface specifications.

Q: What is the difference between stainless steel and nickel-plated steel shells?

A: The DEMD9SJF225 features a stainless steel shell, which provides superior corrosion resistance in harsh, chemically aggressive, or marine environments. The 173-E09-213R141 uses nickel-plated steel, which offers adequate corrosion protection for standard industrial applications. Both materials meet UL94 V-0 flammability requirements.

Q: Are the contact finishes equivalent?

A: Both parts feature gold-plated contacts for signal integrity. The DEMD9SJF225 specifies standard gold plating, while the 173-E09-213R141 specifies flash gold plating. Flash plating is a thin gold layer suitable for signal applications and is functionally equivalent to standard plating for this connector category.

Q: Do both parts support the same mounting configuration?

A: Yes. Both the DEMD9SJF225 and 173-E09-213R141 support through-hole, right-angle panel mount installation with identical mechanical interfaces. The female screwlock (4-40) mating feature is identical on both parts.

Q: What is the significance of ROHS3 compliance on the substitute part?

A: ROHS3 represents an updated regulatory standard with enhanced environmental restrictions compared to standard RoHS compliance. The 173-E09-213R141's ROHS3 certification ensures compliance with current and anticipated future environmental regulations, making it suitable for applications subject to stringent regulatory oversight.

Q: Can these connectors be used interchangeably in existing assemblies?

A: Yes, provided that the application current requirement does not exceed 5A. Both parts maintain identical D-Sub shell size (1/DE/E), 9-position pin configuration, solder termination, and right-angle mounting geometry. No PCB layout or assembly process modifications are required for substitution.

Q: What is the operating temperature range for both parts?

A: Both the DEMD9SJF225 and 173-E09-213R141 operate across the identical temperature range of -55°C to 125°C, supporting applications in extreme thermal environments without performance degradation.

Q: How do I determine which part to order for my application?

A: Verify your circuit's maximum continuous current requirement. If ≤5A, either part is acceptable. If >5A, order the DEMD9SJF225. Confirm environmental conditions; if corrosion resistance is critical, specify the primary part. Both parts are actively manufactured and maintain current inventory availability.
