Key Parameters

Substitute Part Grouping Explanation

Equivalent substitution for the L177DFD50SAJ3VFM is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

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

Secondary Compatibility Parameters:

• Current rating (minimum 5A acceptable)
• Voltage rating (minimum 300V acceptable)
• Contact material: Copper Alloy
• Moisture sensitivity level: 1 (Unlimited)

The substitute parts listed below meet all primary criteria and maintain compatibility within the secondary parameter ranges. Variations in backset spacing, contact finish thickness, and flange feature design do not preclude functional equivalence when mechanical integration allows.

Parameter Comparison

Engineering Selection Recommendations

L177DFD50SAJ3VFM (Primary Part): Use this part when RoHS non-compliance is acceptable and the 7.5A current rating is required. This part offers the highest current capacity and includes panel mount features with mounting brackets. Suitable for applications where legacy component specifications are maintained.

09665526616 (HARTING Substitute): This part is functionally equivalent with a 6.5A current rating and ROHS3 compliance. The backset spacing differs at 0.409" (10.40mm) compared to 0.319" (8.10mm) on the main part. Use this substitute when RoHS3 compliance is required and mechanical integration accommodates the increased backset spacing. Contact finish is not specified; verify with manufacturer if gold plating is required for your application.

DDO50S565MTLF (Amphenol ICC FCI Substitute): This part carries the lowest current rating at 5A and is RoHS compliant. It features gold or gold GXT™ contact finish and maintains the same shell material and tin plating as the main part. The backset spacing is 0.409" (10.40mm). Use this substitute when RoHS compliance is mandatory and the 5A current rating meets application requirements. This part is from the same manufacturer family (Amphenol ICC FCI) as the main part.

Compliance Considerations:

• Main part (L177DFD50SAJ3VFM): RoHS non-compliant
• Substitute 09665526616: ROHS3 Compliant
• Substitute DDO50S565MTLF: RoHS Compliant

All three parts are REACH Unaffected and carry ECCN EAR99 classification.

Frequently Asked Questions (FAQ)

Q: Can I use 09665526616 as a direct replacement for L177DFD50SAJ3VFM?

A: The 09665526616 is functionally equivalent in connector style, position count, row configuration, shell size, mounting type, and termination method. However, the backset spacing differs (0.409" vs. 0.319"), which may affect mechanical fit in your panel or PCB layout. Verify that your mechanical design accommodates this spacing difference before substitution.

Q: What is the difference in current rating between these parts?

A: The L177DFD50SAJ3VFM is rated for 7.5A, the 09665526616 for 6.5A, and the DDO50S565MTLF for 5A. Select the part whose current rating meets or exceeds your application's maximum current requirement.

Q: Does the contact finish difference affect compatibility?

A: All parts use copper alloy contacts. The L177DFD50SAJ3VFM and DDO50S565MTLF specify gold finish at 30.0µin (0.76µm) thickness. The 09665526616 does not specify contact finish. If your application requires gold-plated contacts for corrosion resistance or signal integrity, verify the 09665526616 contact finish with HARTING before use.

Q: Are these parts interchangeable from a mating perspective?

A: Yes. All three parts are 50 position D-Sub receptacles with female sockets and identical shell size (5, DD, D layout). They will mate with standard 50 position D-Sub plugs. Mechanical mounting differences (backset spacing and flange features) affect panel integration, not mating compatibility.

Q: What is the impact of RoHS compliance on part selection?

A: The main part (L177DFD50SAJ3VFM) is RoHS non-compliant. If your procurement or end-product requirements mandate RoHS compliance, use either 09665526616 (ROHS3 Compliant) or DDO50S565MTLF (RoHS Compliant). Verify your specific RoHS requirement level with your compliance team.

Q: How do packaging differences affect ordering?

A: The L177DFD50SAJ3VFM is supplied in Tray packaging with 1033 units in stock. The 09665526616 and DDO50S565MTLF are supplied in Bulk packaging with 948 and 611 units in stock respectively. Packaging affects handling, storage, and minimum order quantities. Confirm packaging requirements with your procurement process.

Q: Can I mix these parts in the same assembly?

A: All three parts are functionally equivalent for mating and electrical performance within their respective current ratings. However, mixing parts with different backset spacings in the same panel may create mechanical alignment issues. Maintain consistency within a single assembly design.

Q: What operating temperature range do these parts support?

A: All three parts operate across the identical temperature range of -55°C to 125°C. Temperature performance is equivalent across all substitutes.
