Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L17DBFRBA25SC309 is determined by the following critical parameters:

Core Compatibility Parameters:

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 25
• Number of rows: 2
• Shell size, connector layout: 3 (DB, B)
• Termination method: IDC, Ribbon Cable
• Contact type: Signal

Electrical Compatibility Parameters:

• Current rating: Must support minimum 5A (or application-specific requirements)
• Voltage rating: Must support minimum 250V (or application-specific requirements)
• Material flammability rating: UL94 V-0

Mechanical Compatibility Parameters:

• Mounting type: Free hanging (in-line) or panel mount configurations are functionally distinct and affect board-level integration
• Shell material and finish: Steel construction with various plating options
• Contact finish: Gold or alternative finishes with specified thickness

Regulatory Compliance Parameters:

• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts may differ in mounting configuration, shell finish, contact finish specifications, and current/voltage ratings, provided they maintain the core D-Sub 25-position receptacle architecture and IDC ribbon cable termination method.

Parameter Comparison

Engineering Selection Recommendations

L17DBFRBA25SC309 (Amphenol ICC) - Primary Selection

The L17DBFRBA25SC309 is the recommended primary component for new designs and applications requiring free-hanging, in-line D-Sub 25-position receptacle connectors. This part is currently active in production with full RoHS compliance and provides the highest current rating (5A) and specified voltage rating (250V) among the available options. The gold contact finish with 30.0µin thickness and nickel-plated steel shell ensure reliable signal integrity and corrosion resistance.

09663186500 (HARTING) - Panel Mount Alternative

The 09663186500 is suitable for applications requiring panel-mount configuration with IDC ribbon cable termination. This part is active in production with ROHS3 compliance. The current rating of 2A and unspecified voltage rating indicate this connector is designed for lower-power signal applications. Selection of this part requires confirmation that application current and voltage requirements do not exceed 2A and that panel-mount integration is acceptable.

09663187500 (HARTING) - Panel Mount Alternative, Bulk Packaging

The 09663187500 is functionally equivalent to 09663186500 with identical electrical and mechanical specifications. The primary distinction is bulk packaging rather than tray packaging. This part is active in production with ROHS3 compliance. The same current and voltage limitations apply as noted for 09663186500.

8325-7003 (3M) - Obsolete Status

The 8325-7003 is classified as obsolete and is not recommended for new designs or long-term production applications. While this part maintains UL94 V-0 flammability rating and RoHS compliance, the 1A current rating and unspecified voltage rating represent significant electrical limitations compared to the primary part. The extended operating temperature range (-55°C ~ 105°C) may be relevant for specific environmental applications, but the obsolete status and lower current capacity make this selection unsuitable for standard applications.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09663186500 or 09663187500 directly replace the Amphenol ICC L17DBFRBA25SC309?

A: Direct replacement is not recommended without design review. While both parts share the same D-Sub 25-position receptacle configuration, IDC ribbon cable termination, and shell size, the HARTING parts feature panel-mount configuration versus the free-hanging in-line mounting of the L17DBFRBA25SC309. Additionally, the HARTING parts have a 2A current rating compared to 5A for the Amphenol part. Substitution is only appropriate if the application circuit board design accommodates panel mounting and current requirements do not exceed 2A.

Q: What are the key electrical differences between these substitute parts?

A: The L17DBFRBA25SC309 provides 5A current rating and 250V voltage rating. The HARTING parts (09663186500 and 09663187500) provide 2A current rating with unspecified voltage rating. The 3M 8325-7003 provides only 1A current rating with unspecified voltage rating. Applications requiring currents above 2A per contact must use the L17DBFRBA25SC309.

Q: Are the HARTING parts suitable for applications currently using the L17DBFRBA25SC309?

A: Substitution requires verification that the application meets all of the following criteria: (1) circuit board design supports panel-mount connector configuration, (2) maximum current per contact does not exceed 2A, (3) voltage requirements are compatible with unspecified rating, and (4) operating temperature range is acceptable. If any of these criteria cannot be confirmed, the L17DBFRBA25SC309 must be retained.

Q: Why is the 3M 8325-7003 listed as a substitute if it is obsolete?

A: The 8325-7003 is included in the substitute parts list based on the provided input data indicating it shares the same D-Sub 25-position receptacle architecture and IDC ribbon cable termination. However, obsolete status indicates this part is no longer in active production. The 8325-7003 is not recommended for new designs or applications requiring long-term component availability.

Q: What is the difference between the two HARTING parts (09663186500 and 09663187500)?

A: The 09663186500 is supplied in tray packaging, while the 09663187500 is supplied in bulk packaging. All electrical and mechanical specifications are identical. Selection between these parts depends on packaging requirements and inventory management practices.

Q: Are all substitute parts RoHS compliant?

A: Yes. The L17DBFRBA25SC309 is RoHS Compliant. The HARTING parts (09663186500 and 09663187500) are ROHS3 Compliant. The 3M 8325-7003 is RoHS Compliant. All parts meet RoHS requirements for new designs.

Q: What is the contact finish specification for the HARTING parts?

A: The HARTING parts (09663186500 and 09663187500) do not specify contact finish in the provided data. The L17DBFRBA25SC309 specifies gold contact finish with 30.0µin thickness. Contact finish specifications should be confirmed with the manufacturer before substitution if contact material compatibility is critical to the application.

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

A: No. The L17DBFRBA25SC309 is free-hanging in-line configuration, while the HARTING parts are panel-mount configuration. These represent fundamentally different mechanical integration approaches and cannot be used interchangeably without circuit board redesign. Additionally, current rating differences must be verified against application requirements.
