Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

• Connector type: D-Sub receptacle, female sockets
• Number of positions: 9
• Shell size and layout: 1 (DE, E)
• Mounting type: Free hanging (in-line)
• Termination method: Solder cup
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (unlimited)

All substitute parts listed maintain these core specifications. Variations in shell material finish, contact finish thickness, current rating, voltage rating, operating temperature range, and contact material are permitted within the scope of electrical and mechanical compatibility for D-Sub 9-position receptacle applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: A-DF 09 LL/Z

The A-DF 09 LL/Z is the direct equivalent from Assmann WSW Components. It maintains identical electrical and mechanical specifications to the obsolete A-DF09LL-TL-B-R while holding active product status. This part is RoHS3 compliant and carries 17502 units in current inventory, providing reliable long-term availability.

Secondary Substitutes: Amphenol ICC (FCI) DE-Series

The DE09S064TLF, DE09S064HTLF, DE09S065TLF, DE09S065HTLF, DEM09S, and DEO09S064TLF are all active Amphenol ICC (FCI) alternatives. These parts exceed the original specifications in current rating (5A to 7.5A per contact versus 3A) and voltage rating (300V versus 250V), with extended operating temperature ranges (-55°C to 125°C versus -55°C to 105°C). All maintain UL94 V-0 flammability rating and MSL 1 classification. Selection among these variants depends on specific application requirements regarding shell finish, contact finish specification, shielding features, and packaging format.

Compliance Considerations

The A-DF 09 LL/Z maintains REACH unaffected status matching the original part. Amphenol ICC (FCI) substitutes carry RoHS compliance certifications. DE09S065HTLF and DE09S065TLF maintain REACH unaffected status, while DE09S064HTLF, DE09S064TLF, DEM09S, and DEO09S064TLF are REACH affected. All parts are classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can I use DE09S064TLF as a direct replacement for A-DF09LL-TL-B-R?

A: Yes. Both are 9-position D-Sub receptacles with solder cup termination, identical shell size and layout, and matching flammability and moisture sensitivity ratings. The DE09S064TLF provides higher current capacity (5A per contact versus 3A) and voltage rating (300V versus 250V), making it electrically compatible for applications within the original design envelope.

Q: What is the difference between DE09S064TLF and DE09S065TLF?

A: Both are 9-position D-Sub receptacles from Amphenol ICC (FCI) with identical core specifications. The primary difference is contact finish: DE09S064TLF uses standard gold flash finish, while DE09S065TLF uses gold GXT™ finish with 30.0µin (0.76µm) thickness specification. DE09S065TLF is available in tray packaging; DE09S064TLF is bulk packaged.

Q: Why does DEM09S have a higher current rating?

A: DEM09S uses phosphor bronze contact material and yellow cadmium-plated steel shell, which support higher current capacity (7.5A per contact) compared to the original brass contacts (3A). This part is suitable for applications requiring higher current handling while maintaining the same 9-position D-Sub form factor.

Q: Is the A-DF 09 LL/Z identical to the obsolete A-DF09LL-TL-B-R?

A: Yes. The A-DF 09 LL/Z is the active production equivalent with identical electrical and mechanical specifications, including shell material, contact finish, current rating, voltage rating, operating temperature range, and dielectric material. The primary difference is product status (active versus obsolete) and packaging format (tray versus unspecified).

Q: What packaging options are available?

A: A-DF 09 LL/Z is supplied in tray packaging with 17502 units in inventory. Amphenol ICC (FCI) alternatives are available in bulk (DE09S064HTLF, DE09S064TLF, DEO09S064TLF) or tray (DE09S065HTLF, DE09S065TLF, DEM09S) formats. Packaging selection depends on procurement volume and assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: The A-DF 09 LL/Z is RoHS3 compliant. All Amphenol ICC (FCI) substitutes are RoHS compliant. Compliance status is maintained across all listed alternatives.
