DD50S365TLF Equivalent & Substitute Parts

Part Overview

The DD50S365TLF is a 50-position D-Sub receptacle connector manufactured by Amphenol ICC (FCI). This through-hole solder-terminated connector features female sockets with a 3-row configuration in shell size 5 (DD, D). The part is currently active in production status with full RoHS compliance and MSL Level 1 rating, making it suitable for applications requiring reliable signal connectivity in industrial and commercial environments. Substitute parts become necessary when the primary part experiences supply constraints, obsolescence of related components in a system, or when design requirements permit alternative connector geometries or mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DD50S365TLF is determined by the following critical parameters:

Primary Substitution Criteria:

• Connector type: Receptacle with female sockets
• Position count: 50 positions
• Row configuration: 3 rows
• Shell size: 5 (DD, D)
• Termination method: Solder
• Current capacity: 5A per contact minimum
• Voltage rating: 300V or higher

Secondary Compatibility Factors:

• Mounting configuration: Through hole or panel mount through hole
• Shell material and finish: Steel with tin or equivalent plating
• Contact material and finish: Copper alloy or brass with gold plating
• Operating temperature range: Must encompass or exceed -55°C to 125°C
• Regulatory compliance: RoHS and REACH status

The substitute part 172-050-212R001 (NorComp Inc.) meets all primary criteria with compatible secondary parameters, though it operates within a narrower temperature range (-50°C to 100°C) and carries obsolete product status.

Engineering Selection Recommendations

Primary Selection: DD50S365TLF

The DD50S365TLF remains the preferred component for new designs and ongoing production. It maintains active product status with full RoHS compliance, MSL Level 1 rating, and the widest operating temperature range (-55°C to 125°C). The GXT™ gold contact finish provides enhanced reliability for signal integrity applications. Current inventory of 1,044 pieces supports immediate availability.

Substitute Selection: 172-050-212R001

The 172-050-212R001 qualifies as a functional equivalent when DD50S365TLF supply is unavailable. This part maintains electrical and mechanical compatibility across all critical parameters. However, the following conditions apply:

• Product status is obsolete, limiting long-term availability
• Operating temperature range is restricted to -50°C to 100°C, unsuitable for applications requiring the full -55°C to 125°C envelope
• Panel mount capability provides additional mechanical flexibility not present in the primary part
• ROHS3 compliance and REACH unaffected status confirm regulatory acceptability

Selection of 172-050-212R001 requires verification that application operating temperatures remain within -50°C to 100°C bounds and that panel mount configuration is compatible with the PCB layout.

Frequently Asked Questions (FAQ)

Q: Can 172-050-212R001 replace DD50S365TLF in all applications?

A: Electrical and mechanical compatibility exists for applications operating within -50°C to 100°C. Applications requiring the full -55°C to 125°C temperature range of the DD50S365TLF cannot use this substitute without thermal performance verification.

Q: What is the difference between through-hole and panel mount configurations?

A: Through-hole mounting passes connector leads directly through PCB holes for solder termination. Panel mount through-hole adds a flange for mechanical retention to a panel or enclosure face. Both configurations use identical solder termination and are mechanically compatible with standard PCB layouts designed for through-hole connectors.

Q: Are the contact materials interchangeable?

A: Both parts use gold-plated contacts suitable for signal applications. The DD50S365TLF uses copper alloy base material with GXT™ finish, while 172-050-212R001 uses brass base material with standard gold flash. Both configurations meet 5A per contact current requirements and provide equivalent signal integrity for standard D-Sub applications.

Q: What does RoHS and ROHS3 compliance mean for substitution?

A: Both parts comply with RoHS directives, confirming absence of restricted substances (lead, cadmium, hexavalent chromium, etc.). ROHS3 represents the current regulatory standard. Both parts are acceptable for applications with RoHS requirements.

Q: Is inventory availability a factor in substitution decisions?

A: Yes. DD50S365TLF has 1,044 pieces in stock, while 172-050-212R001 has 754 pieces. Given the obsolete status of 172-050-212R001, the DD50S365TLF should be prioritized for new designs and long-term production planning.
