DDPS50P365128LF Equivalent & Substitute Parts

Part Overview

The DDPS50P365128LF is a 50-position D-Sub plug connector manufactured by Amphenol ICC (FCI) in the DP series. This vertical solder-mount connector is designed for applications requiring robust signal transmission through a standardized D-shaped interface. The part is currently in stock with 883 units available as new original inventory.

D-Sub connectors of this configuration are essential in legacy and industrial systems where standardized 50-position interconnects are specified. Identifying equivalent substitute parts becomes necessary when managing supply chain continuity, addressing component obsolescence, or optimizing procurement across multiple qualified suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DDPS50P365128LF is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 50-position D-Sub plug with male pins
• Physical Layout: 3-row arrangement in shell size 5 (DD, D)
• Electrical Ratings: 350V voltage rating and 3A current capacity
• Termination: Solder-mount technology
• Material Specifications: Steel shell with nickel plating, phosphor bronze contacts with gold finish
• Compliance: RoHS compliance and dielectric material (PBT)

The SDDB-50P(55) from Hirose Electric Co Ltd meets all these criteria and qualifies as a direct substitute. Both connectors share identical electrical and mechanical specifications within the D-Sub 50-position category, differing only in mounting orientation (panel mount vs. vertical solder) and manufacturer series designation.

Parameter Comparison

Engineering Selection Recommendations

Both the DDPS50P365128LF and SDDB-50P(55) are RoHS-compliant connectors with active product status, ensuring compliance with current environmental and regulatory standards. The SDDB-50P(55) carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

Selection between these parts should be based on:

• Supply Availability: DDPS50P365128LF has 883 units in stock; SDDB-50P(55) has 981 units available
• Mounting Configuration: Verify whether vertical solder mount or panel mount through-hole is required for your application
• Supplier Qualification: Confirm that Hirose Electric Co Ltd is an approved supplier in your procurement system
• Lead Time Requirements: Compare delivery schedules from Amphenol ICC and Hirose Electric for your production timeline

Both connectors maintain identical electrical performance and mechanical compatibility within the 50-position D-Sub category.

Frequently Asked Questions (FAQ)

Q: Can the SDDB-50P(55) be used as a direct replacement for the DDPS50P365128LF?

A: The SDDB-50P(55) is electrically and mechanically equivalent in all critical parameters: 50-position configuration, 3-row layout, shell size 5, 350V rating, 3A current capacity, and identical material specifications. However, verify mounting type compatibility with your PCB design, as the DDPS50P365128LF is vertical solder-mount while the SDDB-50P(55) is panel mount through-hole.

Q: What are the key parameters that determine D-Sub 50-position connector substitutability?

A: Substitution is determined by: connector type (plug with male pins), position count (50), row configuration (3), shell size (5/DD/D), termination method (solder), shell material and finish (steel/nickel), contact material and finish (phosphor bronze/gold), voltage rating (350V), current rating (3A), and dielectric material (PBT).

Q: Are there any compliance differences between these connectors?

A: Both connectors are RoHS compliant. The SDDB-50P(55) specifies an MSL rating of 1 (Unlimited), while the DDPS50P365128LF does not provide this specification. MSL 1 indicates no moisture sensitivity constraints.

Q: What should be verified before implementing the SDDB-50P(55) as a substitute?

A: Confirm mounting type compatibility with your circuit board layout, verify Hirose Electric Co Ltd supplier qualification status, and validate that the panel mount through-hole configuration aligns with your PCB design specifications.

Q: How do the contact finish specifications compare?

A: The SDDB-50P(55) specifies a contact finish thickness of 8.00µin (0.203µm). The DDPS50P365128LF does not provide contact finish thickness data. Both use gold plating over phosphor bronze contacts.
