DDPS50P365TXLF Equivalent & Substitute Parts

Part Overview

The DDPS50P365TXLF is a 50-position D-Sub plug connector manufactured by Amphenol ICC (FCI) with male pins and vertical solder termination. This connector is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The part features a DD/D shell size (Size 5) with three-row configuration and is designed for through-hole mounting applications requiring signal-level connectivity at up to 7.5A per contact.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DDPS50P365TXLF is determined by the following critical parameters:

• Connector Style & Type: Must be D-Sub plug with male pins
• Position & Row Configuration: Must maintain 50 positions in 3-row arrangement
• Shell Size: Must be Size 5 (DD, D) layout
• Termination Method: Must support solder termination
• Contact Type: Must be signal-level contacts
• Flammability Compliance: Must meet UL94 V-0 rating
• Voltage Rating: Must equal or exceed 300V
• Operating Temperature: Must support -55°C ~ 125°C range
• MSL Rating: Must be MSL 1 or equivalent

The SDDB-50P(55) from Hirose Electric Co Ltd satisfies all critical substitution parameters while maintaining functional and electrical compatibility with the original DDPS50P365TXLF specification.

Parameter Comparison

Engineering Selection Recommendations

The SDDB-50P(55) is a valid substitute for the obsolete DDPS50P365TXLF based on matching connector geometry, pin configuration, termination method, and compliance ratings. The substitute part maintains UL94 V-0 flammability compliance and exceeds the voltage rating requirement at 350V versus 300V.

A critical consideration exists regarding current rating: the SDDB-50P(55) is rated for 3A per contact, while the original DDPS50P365TXLF supports 7.5A per contact. Applications requiring current levels between 3A and 7.5A per contact must evaluate whether the reduced current capacity of the substitute part is acceptable for the intended circuit design.

The SDDB-50P(55) is an active product with current manufacturing availability, eliminating obsolescence concerns associated with the original part. Both parts carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can the SDDB-50P(55) be used as a direct replacement for the DDPS50P365TXLF in existing designs?

A: The SDDB-50P(55) provides mechanical and electrical compatibility for connector mating and signal routing. However, the reduced current rating (3A versus 7.5A per contact) must be evaluated against circuit requirements. If the application operates at or below 3A per contact, direct substitution is feasible.

Q: What are the key differences between these two 50-position D-Sub plugs?

A: Both connectors share identical mechanical form factors (50 positions, 3 rows, Size 5 shell, solder termination). Primary differences include: manufacturer (Amphenol ICC versus Hirose Electric), product status (obsolete versus active), current rating (7.5A versus 3A), shell material finish (tin plated versus nickel plated), contact material (copper alloy versus phosphor bronze), and contact finish thickness (30.0µin versus 8.00µin).

Q: Are there packaging or mounting differences between these parts?

A: The DDPS50P365TXLF is specified for through-hole mounting with board-side flange. The SDDB-50P(55) supports both panel mount and through-hole configurations with housing/shell unthreaded flange. Both parts use solder termination and are compatible with standard PCB assembly processes.

Q: What compliance certifications apply to both parts?

A: Both the DDPS50P365TXLF and SDDB-50P(55) meet UL94 V-0 material flammability requirements and carry MSL 1 moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040 for export and tariff purposes.

Q: Why is the DDPS50P365TXLF listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Amphenol ICC. The SDDB-50P(55) from Hirose Electric represents an active alternative with current production and supply availability.
