Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub 50 position receptacle connectors is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 50
• Number of rows: 3
• Shell size and connector layout: 5 (DD, D)
• Mounting type: Through Hole, Right Angle
• Termination method: Solder
• Operating temperature range: -55°C ~ 125°C
• Material flammability rating: UL94 V-0

Allowable Variation Parameters:

• Current rating: Substitute must meet or exceed the application requirement
• Voltage rating: Substitute must meet or exceed the application requirement
• Packaging format: Tray or Bulk
• Contact finish: Gold or equivalent conductive finish
• Shell material finish: Steel with or without tin plating
• RoHS compliance status: May differ based on application requirements

The two substitute parts identified (09665526616 and DDO50S565MTLF) satisfy all mandatory matching parameters and represent valid alternatives within the D-Sub 50 position receptacle category.

Parameter Comparison

Engineering Selection Recommendations

L177DFD50SAJ3VF (Primary Part): This connector is suitable for applications where RoHS non-compliance is acceptable and the 7.5A current rating is required. The tin-plated steel shell with gold-plated contacts provides reliable performance in industrial environments. Active production status ensures continued availability.

09665526616 (HARTING Substitute): This part is appropriate for applications requiring ROHS3 compliance. The 6.5A current rating is lower than the primary part; applications requiring the full 7.5A rating must verify that 6.5A meets system requirements. The stamped contact form differs from the machined contacts of the primary part. Bulk packaging format requires consideration for inventory management. Board lock feature provides additional mechanical retention.

DDO50S565MTLF (Amphenol ICC / FCI Substitute): This part is appropriate for applications requiring RoHS compliance. The 5A current rating is the lowest among the three options; applications requiring higher current capacity must verify compatibility. The part is manufactured by Amphenol ICC (FCI division), maintaining manufacturer consistency with the primary part. Gold or Gold GXT™ contact finish provides equivalent or enhanced performance. Bulk packaging format requires consideration for inventory management.

Selection Criteria:

• If RoHS compliance is not required and 7.5A current capacity is necessary, use L177DFD50SAJ3VF
• If ROHS3 compliance is required and 6.5A current capacity is acceptable, use 09665526616
• If RoHS compliance is required and 5A current capacity is acceptable, use DDO50S565MTLF

Frequently Asked Questions (FAQ)

Q: Can DDO50S565MTLF be used as a direct replacement for L177DFD50SAJ3VF?

A: DDO50S565MTLF is mechanically and electrically compatible with L177DFD50SAJ3VF for applications requiring 5A or less. The 5A current rating of DDO50S565MTLF is lower than the 7.5A rating of L177DFD50SAJ3VF. Applications requiring the full 7.5A capacity must use the primary part or verify that the substitute's 5A rating meets system requirements.

Q: What is the difference between the contact forms in these connectors?

A: L177DFD50SAJ3VF uses machined contacts, while 09665526616 uses stamped contacts. Both contact forms are acceptable for D-Sub 50 position receptacles. Machined contacts typically provide slightly higher reliability in high-cycle mating applications, while stamped contacts reduce manufacturing cost. For most industrial applications, both forms are functionally equivalent.

Q: Does the difference in backset spacing affect compatibility?

A: Backset spacing (the distance from the mating face to the solder cup) differs between parts: L177DFD50SAJ3VF has 0.319" (8.10mm), while 09665526616 and DDO50S565MTLF have 0.409" (10.40mm). This parameter affects panel thickness compatibility and PCB layout. Verify that the substitute's backset spacing accommodates the intended installation panel thickness before selection.

Q: Are there RoHS compliance implications for these substitutes?

A: L177DFD50SAJ3VF is RoHS non-compliant. 09665526616 is ROHS3 compliant. DDO50S565MTLF is RoHS compliant. Applications subject to RoHS regulations must use either 09665526616 or DDO50S565MTLF. Applications without RoHS requirements may use any of the three parts.

Q: What packaging considerations apply to these parts?

A: L177DFD50SAJ3VF is supplied in Tray packaging (779 pieces in stock). 09665526616 is supplied in Bulk packaging (948 pieces in stock). DDO50S565MTLF is supplied in Bulk packaging (611 pieces in stock). Bulk packaging typically requires reel or tape format handling. Verify that receiving and handling procedures accommodate the substitute's packaging format.

Q: Can 09665526616 be used in applications requiring 7.5A?

A: 09665526616 has a 6.5A current rating, which is lower than the 7.5A requirement of L177DFD50SAJ3VF. This part is not suitable for applications requiring the full 7.5A capacity. Use only in applications where the actual current draw is 6.5A or less.
