A-DFF09LPIII/FP-R D-Sub 9 Position IDC Receptacle Connector

Part Overview

The A-DFF09LPIII/FP-R is a 9 position D-Sub receptacle connector with IDC (Insulation Displacement Contact) termination for ribbon cable applications. This connector features female sockets in a DE/E shell size configuration with gold-plated contacts and integrated strain relief. The part is currently listed as obsolete, necessitating identification of active substitute components that maintain electrical and mechanical compatibility for ongoing production and field replacement requirements.

Substitute Part Grouping Explanation

Substitution of the A-DFF09LPIII/FP-R is determined by strict equivalence across the following critical parameters:

Connector style, type, and position count (D-Sub receptacle, 9 position, female sockets)
Shell size and layout (DE/E, Size 1)
Mounting configuration (free hanging, in-line)
Termination method (IDC ribbon cable)
Electrical ratings (3A current, 250V voltage)
Operating temperature range (-55°C to 105°C)
Contact material and finish (copper alloy, gold flash)
Dielectric material (PBT, glass filled)
Flammability compliance (UL94 V-0)

The identified substitutes maintain full compatibility across all these parameters. Variations in packaging format and shell material finish do not affect functional interchangeability in the connector interface.

Engineering Selection Recommendations

Both A-DFF 09 LPIII/FP and A-DFF 09 LPIII/Z are direct functional equivalents to the obsolete A-DFF09LPIII/FP-R. Selection between these active substitutes should be based on the following criteria:

A-DFF 09 LPIII/FP is supplied in tray packaging and maintains all electrical and mechanical specifications identical to the main part. This variant is suitable for standard production environments where packaging format does not impose constraints.

A-DFF 09 LPIII/Z is also supplied in tray packaging and is designated as the manufacturer-recommended substitute. This variant features a steel shell material finish compared to the unspecified shell material of the main part, while maintaining all other functional parameters. Higher inventory availability (8252 units) supports supply chain continuity.

Both substitutes carry ROHS3 compliance certification, providing enhanced regulatory alignment for new designs and ongoing production. The obsolete status of the main part necessitates transition to one of these active alternatives for all new procurement and field replacement applications.

Frequently Asked Questions (FAQ)

Q: Can A-DFF 09 LPIII/FP and A-DFF 09 LPIII/Z be used interchangeably with A-DFF09LPIII/FP-R?

A: Yes. Both substitutes maintain full electrical and mechanical compatibility. All critical parameters including connector type, position count, shell size, termination method, current and voltage ratings, operating temperature range, and contact specifications are identical.

Q: What is the difference between the two substitute parts?

A: The primary differences are packaging format and shell material finish. A-DFF 09 LPIII/FP has unspecified shell material, while A-DFF 09 LPIII/Z specifies steel shell material. Both are supplied in tray packaging. Functionally, they are equivalent for connector interface applications.

Q: Why is the main part listed as obsolete?

A: The A-DFF09LPIII/FP-R is no longer in active production. The active substitutes A-DFF 09 LPIII/FP and A-DFF 09 LPIII/Z provide equivalent functionality and are recommended for all new designs and replacement applications.

Q: Are there any compliance differences between the main part and substitutes?

A: The substitutes carry ROHS3 compliance certification, which is not specified for the main part. Both substitutes maintain REACH Unaffected status and EAR99 export classification identical to the main part.

Q: What wire gauge is compatible with these connectors?

A: All three parts support 26-28 AWG ribbon cable for IDC termination.

Q: What is the maximum current and voltage these connectors can handle?

A: All three parts are rated for 3A current and 250V voltage.

Q: What is the operating temperature range?

A: All three parts operate across -55°C to 105°C.
