A-DFF15LPIII/FP-R D-Sub 15 Position IDC Receptacle Connector

Part Overview

The A-DFF15LPIII/FP-R is a 15 position D-Sub receptacle connector with IDC (Insulation Displacement Contact) termination for ribbon cable applications. This connector features female sockets in a 2-row configuration with shell size 2 (DA, A) layout. The part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-DFF15LPIII/FP-R is determined by strict alignment with the following core parameters:

• Connector Style & Type: Must be D-Sub receptacle with female sockets
• Position & Row Configuration: Must maintain 15 positions in 2-row layout
• Shell Size: Must be size 2 (DA, A)
• Termination Method: Must support IDC ribbon cable termination
• Electrical Ratings: Current rating minimum 3A, voltage rating minimum 250V
• Operating Temperature Range: Must support -55°C to 105°C
• Flammability Compliance: Must meet UL94 V-0 standard
• Contact Finish: Gold plating required for signal integrity

Two substitute parts meet these criteria: the A-DFF 15 LPIII/FP from Assmann WSW Components (same manufacturer, active product status) and the L17DAFRA15S from Amphenol ICC (alternative manufacturer, active product status).

Parameter Comparison

Engineering Selection Recommendations

A-DFF 15 LPIII/FP (Assmann WSW Components): This substitute is the primary recommendation for direct replacement. It is manufactured by the same supplier as the obsolete part, maintains identical electrical and mechanical specifications, and carries active product status. RoHS3 compliance provides regulatory advantage for new designs. Packaging is supplied in trays with 1056 units in stock.

L17DAFRA15S (Amphenol ICC): This alternative substitute meets all core substitution criteria and is suitable where multi-source qualification is required. The part maintains identical connector geometry, electrical ratings, and termination method. Minor material variations exist in contact material (brass versus copper alloy) and dielectric composition (thermoplastic versus PBT), which remain functionally compatible within the specified electrical and thermal operating envelope. Wire gauge specification is 26 AWG (versus 26-28 AWG range). RoHS3 compliance and active product status support long-term availability. Inventory availability is 1736 units in trays.

Both substitutes are qualified for applications requiring UL94 V-0 flammability compliance and operate across the full -55°C to 105°C temperature range with 3A current and 250V voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can the A-DFF 15 LPIII/FP be used as a direct replacement for the A-DFF15LPIII/FP-R?

A: Yes. Both parts share identical connector specifications, electrical ratings, and IDC ribbon cable termination. The primary difference is product status (active versus obsolete) and packaging format (tray versus unspecified). Mechanical and electrical compatibility is complete.

Q: What are the key differences between the Assmann and Amphenol substitutes?

A: Both parts maintain identical D-Sub 15-position, 2-row receptacle configuration with IDC termination. Differences include: contact material (copper alloy versus brass), dielectric material composition (PBT glass-filled versus thermoplastic glass-filled), and wire gauge specification (26-28 AWG range versus 26 AWG fixed). All differences remain within functional compatibility for the specified electrical and thermal operating conditions.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both A-DFF 15 LPIII/FP and L17DAFRA15S carry ROHS3 compliance certification. The original obsolete part does not specify RoHS status.

Q: What is the wire gauge compatibility consideration?

A: The A-DFF 15 LPIII/FP supports 26-28 AWG ribbon cable, matching the original specification. The L17DAFRA15S is specified for 26 AWG. Both are compatible with standard ribbon cable gauges used in D-Sub IDC applications.

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

A: Yes. Both substitute parts maintain identical shell size (2/DA, A), mounting type (free hanging in-line), and IDC termination method. Mechanical fit and electrical performance are equivalent for mating with standard D-Sub 15-position plugs.

Q: What inventory levels are available for these substitutes?

A: A-DFF 15 LPIII/FP: 1056 units in stock (tray packaging). L17DAFRA15S: 1736 units in stock (tray packaging).
