Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-DF50LL-TL-B-R is determined by strict equivalence across the following critical parameters:

• Connector style and type (D-Sub receptacle with female sockets)
• Position count and row configuration (50 positions, 3 rows)
• Shell size and layout designation (Size 5, DD/D configuration)
• Mounting method (free hanging in-line)
• Termination technology (solder cup)
• Electrical ratings (250V, 3A)
• Temperature operating range (-55°C ~ 105°C)
• Material specifications and flammability compliance (UL94 V-0)

The substitute part A-DF 50 LL/Z meets all these criteria and is therefore electrically and mechanically interchangeable with the original part number.

Parameter Comparison

Engineering Selection Recommendations

The A-DF 50 LL/Z is the direct substitute for the obsolete A-DF50LL-TL-B-R. Both parts are manufactured by Assmann WSW Components and share identical electrical and mechanical specifications across all critical parameters. The substitute part is currently in active production status with confirmed inventory availability.

The A-DF 50 LL/Z carries ROHS3 compliance certification, providing enhanced environmental and regulatory alignment for new designs and system upgrades. Both parts maintain equivalent performance characteristics for applications requiring 50 position D-Sub receptacle connectors with solder cup termination in the -55°C to 105°C operating range.

Frequently Asked Questions (FAQ)

Q: Are A-DF50LL-TL-B-R and A-DF 50 LL/Z electrically interchangeable?

A: Yes. Both connectors share identical voltage ratings (250V), current ratings (3A), and contact specifications. They are electrically equivalent for all applications requiring 50 position D-Sub receptacle connectivity.

Q: Are these connectors mechanically compatible?

A: Yes. Both parts feature identical shell size (Size 5, DD/D), position count (50), row configuration (3 rows), and mounting method (free hanging in-line). They are mechanically interchangeable without modification.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. The A-DF50LL-TL-B-R is obsolete, while the A-DF 50 LL/Z is in active production. The substitute part also includes ROHS3 compliance certification and is supplied in tray packaging.

Q: Can I use A-DF 50 LL/Z as a direct replacement in existing designs?

A: Yes. The A-DF 50 LL/Z is a direct substitute with no design modifications required. All electrical and mechanical parameters are equivalent to the original part.

Q: What packaging is available for the substitute part?

A: The A-DF 50 LL/Z is supplied in tray packaging. Inventory availability is confirmed at 1010 pieces.
