L117DBFRDA25P D-Sub 25 Position IDC Plug Connector - Equivalent & Substitute Parts

Part Overview

The L117DBFRDA25P is a 25 position D-Sub plug connector manufactured by Amphenol ICC, designed for IDC ribbon cable termination in free hanging (in-line) mounting configurations. This connector features male pins, nickel-plated steel shell, and gold-plated contacts rated for 5A at 250V operation across -40°C to 125°C temperature range. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the original L117DBFRDA25P becomes unavailable, when alternative mounting configurations are required, or when design specifications allow for compatible alternatives from qualified manufacturers. Substitute selection must maintain compatibility across connector style, position count, termination method, and electrical ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the L117DBFRDA25P is based on the following critical parameters that must remain constant or compatible:

Mandatory Matching Parameters:

• 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

Allowable Variation Parameters:

• Mounting Type: Free Hanging (In-Line) or Panel Mount configurations are functionally distinct but both support 25-position D-Sub IDC termination
• Current Rating: Substitute parts rated at 1A are acceptable for applications not requiring the full 5A capacity of the original
• Operating Temperature: Substitute parts with -55°C ~ 105°C range are acceptable as they encompass the original -40°C ~ 125°C specification within overlapping operational bounds
• Shell Material Finish: Nickel Plated or Tin Plated finishes are both acceptable for D-Sub connectors
• Contact Finish: Gold plating at varying thicknesses (15.0µin to 30.0µin) maintains contact integrity

Compliance Parameters:

• RoHS Status: RoHS Compliant or ROHS3 Compliant are equivalent
• Moisture Sensitivity Level: MSL 1 (Unlimited) is consistent across all qualified substitutes

Substitutes are grouped by mounting configuration (Free Hanging vs. Panel Mount) and product status (Active vs. Obsolete). Active status substitutes are preferred for new designs.

Parameter Comparison

Engineering Selection Recommendations

For Free Hanging (In-Line) Mounting Applications:

The L117DBFRDA25P and A-DSF 25 LPIII/Z-UNC are the only active substitutes maintaining free hanging in-line mounting configuration. Both are RoHS3 compliant and support IDC ribbon cable termination for 25-position D-Sub connectors.

• L117DBFRDA25P (Amphenol ICC): Primary specification. 5A current rating, 250V voltage rating, -40°C ~ 125°C operating range. Nickel-plated steel shell with 15.0µin gold contact finish.

• A-DSF 25 LPIII/Z-UNC (Assmann WSW Components): Direct functional equivalent for free hanging applications. 3A current rating, 250V voltage rating, -55°C ~ 105°C operating range. Tin-plated steel shell with flash gold contact finish. Supports 26-28 AWG wire gauge. ROHS3 compliant with REACH unaffected status.

For Panel Mount Applications (When Mounting Configuration Change is Acceptable):

The 3M 8200 series connectors (8225-6000, 8225-6003, 8225-8000) provide panel mount alternatives. All are active status, ROHS3 compliant, and support IDC ribbon cable termination.

• 8225-8000 (3M): Preferred panel mount substitute. Active status, 1A current rating, -55°C ~ 105°C operating range, tin-plated steel shell, 30.0µin gold contact finish. Feed through and grounding indent features. Bulk packaging.

• 8225-6000 (3M): Panel mount alternative with unthreaded housing/shell flange. Active status, 1A current rating, tin-plated steel shell, 30.0µin gold contact finish. Tray packaging.

• 8225-6003 (3M): Panel mount alternative with 4-40 housing/shell flange. Active status, 1A current rating, tin-plated steel shell, 30.0µin gold contact finish. REACH affected status. Tray packaging.

Obsolete Status Parts (Not Recommended for New Designs):

• 8225-7000 (3M): Obsolete status. Panel mount, 1A current rating, grounding indents feature only (no feed through). RoHS compliant.

• 8225-7003 (3M): Obsolete status. Panel mount with 4-40 housing/shell flange, 1A current rating, grounding indents feature only. RoHS compliant.

Current Rating Considerations:

Substitutes rated at 1A (3M 8200 series) are acceptable only for applications where circuit current does not exceed 1A. The L117DBFRDA25P 5A rating and A-DSF 25 LPIII/Z-UNC 3A rating support higher current applications. Verify application current requirements before selecting 1A-rated substitutes.

Temperature Range Considerations:

The L117DBFRDA25P operates -40°C ~ 125°C. All substitute parts operate -55°C ~ 105°C. The substitute range does not extend to the original +125°C maximum. Applications requiring operation above 105°C must retain the L117DBFRDA25P or verify substitute acceptability with system thermal analysis.

Frequently Asked Questions (FAQ)

Q: Can I use an 8225-6000 (3M) as a direct replacement for L117DBFRDA25P?

A: The 8225-6000 is functionally compatible for 25-position D-Sub IDC ribbon cable termination but differs in mounting type (panel mount vs. free hanging in-line) and current rating (1A vs. 5A). If your application uses panel mount configuration and circuit current does not exceed 1A, the 8225-6000 is compatible. If free hanging in-line mounting is required, use A-DSF 25 LPIII/Z-UNC instead.

Q: What is the difference between the 3M 8225-6000, 8225-6003, and 8225-8000?

A: All three are 25-position D-Sub IDC plug connectors with panel mount configuration, 1A current rating, and tin-plated steel shells. The differences are: 8225-6000 has unthreaded housing/shell flange and tray packaging; 8225-6003 has 4-40 housing/shell flange, tray packaging, and REACH affected status; 8225-8000 has unthreaded housing/shell flange, bulk packaging, and feed through feature. Select based on flange type requirement and packaging preference.

Q: Why are the 3M 8225-7000 and 8225-7003 marked obsolete?

A: These parts are obsolete status and should not be selected for new designs. Active status alternatives (8225-6000, 8225-6003, 8225-8000) provide equivalent functionality with ongoing manufacturer support and supply availability.

Q: Can I substitute L117DBFRDA25P with A-DSF 25 LPIII/Z-UNC in a 5A application?

A: The A-DSF 25 LPIII/Z-UNC is rated for 3A maximum current. Applications requiring 5A operation must use the L117DBFRDA25P or verify that actual circuit current does not exceed 3A. Do not exceed the connector current rating.

Q: What is the difference between nickel plating and tin plating on the shell?

A: Both nickel and tin plating provide corrosion resistance on steel D-Sub shells. Nickel plating (L117DBFRDA25P) and tin plating (3M and Assmann substitutes) are both acceptable finishes for standard industrial applications. Selection is based on application environment and design specification requirements.

Q: Are all these connectors RoHS compliant?

A: Yes. The L117DBFRDA25P is RoHS compliant. All substitute parts are ROHS3 compliant, which is equivalent. All parts meet RoHS requirements for hazardous substance restrictions.

Q: What does IDC termination mean?

A: IDC (Insulation Displacement Contact) termination allows ribbon cable to be inserted directly into the connector without stripping insulation. The connector contacts pierce the cable insulation and make electrical connection. All listed parts support IDC ribbon cable termination for 26 AWG or 26-28 AWG wire gauges.

Q: Can I use these connectors in high-temperature applications above 105°C?

A: The L117DBFRDA25P operates to 125°C. All substitute parts operate to 105°C maximum. For applications requiring operation above 105°C, the L117DBFRDA25P must be retained. Verify substitute acceptability through thermal analysis if operation near 105°C is required.

Q: What is the difference between tray and bulk packaging?

A: Tray packaging provides individual compartments for connector protection during storage and shipment. Bulk packaging provides loose connectors in a container. Tray packaging is preferred for component traceability and handling. Select based on inventory management and handling requirements.

Q: Are the contact finish thicknesses (15.0µin vs. 30.0µin vs. flash) functionally different?

A: All gold contact finishes provide electrical conductivity and corrosion resistance. Thicker finishes (30.0µin) provide extended contact life under repeated mating cycles. Flash gold provides minimal coverage for cost reduction. For standard applications, all finishes are functionally equivalent. High-cycle mating applications may benefit from thicker finishes.
