L17DBFRDA25P

Part Overview

The L17DBFRDA25P is a 25-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products) with IDC termination for ribbon cable applications. This free-hanging (in-line) connector features male pins, tin-plated steel shell with gold-plated contacts, and is currently active in production status. Alternative and substitute parts are necessary to address specific application requirements, including different mounting configurations, contact ratings, and component availability across multiple sourcing channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the L17DBFRDA25P is determined by the following critical parameters that must align for direct replacement:

Core Substitution Criteria:

• Connector Style: D-Sub
• Connector Type: Plug, Male Pins
• Number of Positions: 25
• Number of Rows: 2
• Shell Size, Connector Layout: 3 (DB, B)
• Termination: IDC, Ribbon Cable
• Shell Material, Finish: Steel, Tin Plated
• Contact Finish: Gold
• Material Flammability Rating: UL94 V-0
• Operating Temperature Range: -55°C to 105°C

Allowable Variation Parameters (do not preclude substitution):

• Mounting Type: Free Hanging (In-Line) or Panel Mount connectors may serve different application contexts
• Current Rating: Lower current ratings (1A or 1.25A) are acceptable for applications not exceeding those thresholds
• Voltage Rating: If not specified for substitute, does not prevent substitution provided no application exceeds the main part specification
• Wire Gauge: Variations from 26 AWG to 26-28 AWG (stranded or solid) accommodate different ribbon cable configurations
• Contact Material: Brass or Copper Alloy/Phosphor Bronze are functionally equivalent for signal contacts
• Packaging: Tray or Bulk packaging does not affect connector function

Substitute parts are grouped based on these criteria. All listed substitute parts share the core substitution criteria with the main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Active Alternatives (Recommended for New Designs):

The following substitute parts are in active production status and meet all core substitution criteria for the L17DBFRDA25P:

• 1658608-2 (TE Connectivity AMP Connectors): Active status with identical core specifications. Current rating of 1.25A suits applications below 3A requirements. RoHS Compliant. Wire gauge specification of 26-28 AWG accommodates standard ribbon cable configurations.

• 8225-6000, 8225-6009, 8225-8000 (3M 8200 Series): All three parts are active status with ROHS3 Compliant certification. These connectors employ panel mount configuration in place of the free-hanging mounting of the main part. Current rating of 1A requires applications below this threshold. Suitable for installations where panel mount integration is required.

• A-DSF 25 LPIII/Z-UNC (Assmann WSW Components): Active production status with identical current rating (3A) and voltage rating (250V) to the main part. Free-hanging (in-line) mounting matches the L17DBFRDA25P configuration. ROHS3 Compliant. Highest inventory availability (6033 pcs).

Secondary Alternatives (Limited to Existing Designs):

The following substitute parts are designated obsolete status and are not recommended for new designs:

• 8225-7000, 8225-7003 (3M 8200 Series): Obsolete status. Both parts are in stock but no longer in production. Use only for replacement in existing systems where no alternative is available.

Current Rating Considerations:

The L17DBFRDA25P specifies 3A current rating. Substitute parts with lower current ratings (1A or 1.25A) are acceptable only for applications demonstrating current draw below their rated specification.

Frequently Asked Questions (FAQ)

Q: Can I replace the L17DBFRDA25P with a lower current-rated substitute such as the 3M 8225-6000?

A: Yes, if your application current draw does not exceed 1A. The 8225-6000 meets all core substitution criteria (connector type, position count, shell size, IDC termination, UL94 V-0 rating, operating temperature). The 1A current rating is a design limit, not a functional incompatibility. Confirm your circuit current requirements before selection.

Q: What is the difference between the free-hanging mounting of the L17DBFRDA25P and the panel mount substitutes from 3M?

A: Mounting type defines the physical installation method. Free-hanging (in-line) connectors attach directly to ribbon cable without requiring a panel aperture. Panel mount connectors insert through a panel opening with threaded or unthreaded flanges. Core connector function, pin layout, and electrical characteristics remain identical. Select based on your physical installation architecture.

Q: Are the Assmann A-DSF 25 LPIII/Z-UNC and Amphenol L17DBFRDA25P directly compatible?

A: Yes. Both are 25-position D-Sub plug connectors with identical core specifications: free-hanging mounting, 3A current rating, 250V voltage rating, UL94 V-0 rating, and -55°C to 105°C operating temperature. Contact material differs (Copper Alloy vs. Brass) and wire gauge varies (26-28 AWG vs. 26 AWG), but these variations do not preclude substitution. Assmann part is currently in higher inventory (6033 pcs vs. 813 pcs).

Q: Can I use the TE Connectivity 1658608-2 if my application requires the full 3A current rating of the L17DBFRDA25P?

A: No. The 1658608-2 is rated for maximum 1.25A continuous current, below the 3A specification of the main part. Exceeding this rating risks contact overheating and connector failure. Use only in applications with confirmed current draw below 1.25A, or select the Assmann A-DSF 25 LPIII/Z-UNC or Amphenol L17DBFRDA25P.

Q: What is the significance of RoHS versus ROHS3 compliance in substitute selection?

A: Both RoHS and ROHS3 represent regulatory compliance with hazardous substance restrictions. ROHS3 is the current implementation. The difference does not affect electrical performance or connector function. Select based on your system compliance requirements and regional regulatory obligations.

Q: The 3M 8225-7000 and 8225-7003 are listed as obsolete. Should I avoid them?

A: Obsolete designation indicates the manufacturer no longer produces these parts. Current inventory is available (683 pcs and 1175 pcs respectively), but future availability is not guaranteed. These parts meet all core substitution criteria and may be used for replacement in existing systems. For new designs, select from active status parts such as 8225-6000, 8225-6009, 8225-8000, or the Assmann and TE alternatives.

Q: How do wire gauge variations (26 AWG vs. 26-28 AWG) affect connector compatibility?

A: Wire gauge specification defines the compatible ribbon cable diameter range. The L17DBFRDA25P specifies 26 AWG. Substitutes offering 26-28 AWG (such as 1658608-2 and A-DSF 25 LPIII/Z-UNC) accommodate a wider cable range while maintaining compatibility with 26 AWG cable. The variation does not preclude substitution; rather, it expands compatible cable options.

Q: What inventory considerations should influence my substitute part selection?

A: Inventory levels are provided for immediate supply assessment. The Assmann A-DSF 25 LPIII/Z-UNC offers the highest availability (6033 pcs). The Amphenol L17DBFRDA25P has 813 pcs in stock. TE Connectivity 1658608-2 offers 1885 pcs. For high-volume production or critical applications, inventory depth may influence sourcing strategy alongside electrical and mechanical compatibility.
