PHEC50P-SC11LF Equivalent & Substitute Parts

Part Overview

The PHEC50P-SC11LF is a 50-position D-Sub plug connector manufactured by Amphenol ICC (FCI) in the PHEC series. This through-hole solder connector features center strip contacts and is actively produced. The connector is specified for applications requiring a 50-position vertical plug configuration with gold-plated contacts. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate alternative suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHEC50P-SC11LF is determined by the following critical parameters:

• 50-position connector configuration
• 2-row arrangement
• Plug connector type
• Through-hole solder termination
• Center strip contact style
• Gold contact finish
• MSL 1 rating

The substitute part 5-5175473-6 (TE Connectivity AMP Connectors) meets all core electrical and mechanical compatibility criteria. While this substitute is specified as a board-to-board connector with board lock features, it maintains functional equivalence for the primary electrical and mechanical parameters that define substitutability within the D-Sub connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the PHEC50P-SC11LF and 5-5175473-6 are active products with identical product status and regulatory classifications (EAR99, HTSUS 8536.69.4040). Both connectors carry MSL 1 ratings, indicating unlimited moisture sensitivity protection requirements.

The primary distinction between these parts is the contact finish thickness specification. The PHEC50P-SC11LF specifies 3.94µin (0.10µm) gold plating, while the 5-5175473-6 specifies 30.0µin (0.76µm) gold plating. The substitute part provides thicker gold plating, which may offer enhanced durability in high-cycle mating applications.

Selection between these parts should be based on design requirements, inventory availability, and supplier lead times. Both parts satisfy the core electrical and mechanical parameters for D-Sub 50-position plug connectors with through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: Can the 5-5175473-6 directly replace the PHEC50P-SC11LF in existing designs?

A: The 5-5175473-6 meets all core electrical and mechanical compatibility parameters: 50-position configuration, 2-row arrangement, plug type, through-hole solder termination, center strip contacts, and gold finish. Physical form factor and pin assignment compatibility must be verified against your specific application requirements and PCB layout.

Q: What is the significance of the contact finish thickness difference?

A: The PHEC50P-SC11LF specifies 3.94µin (0.10µm) gold plating, while the 5-5175473-6 specifies 30.0µin (0.76µm) gold plating. Thicker gold plating may provide improved wear resistance in applications with frequent mating cycles. Design specifications should dictate the acceptable range for contact finish thickness.

Q: Are there packaging differences between these parts?

A: The PHEC50P-SC11LF is supplied in Tray packaging, while the 5-5175473-6 is supplied in Bag packaging. Packaging format may affect handling, storage, and integration into assembly processes.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both parts are classified under ECCN EAR99 and HTSUS code 8536.69.4040. Both carry MSL 1 ratings. The 5-5175473-6 is specified as ROHS3 Compliant; RoHS status for the PHEC50P-SC11LF is not provided in the available data.

Q: What distinguishes the board-to-board designation of the 5-5175473-6?

A: The 5-5175473-6 is specified as a board-to-board connector with board lock features. This designation indicates mechanical design features intended for board-to-board applications. Functional electrical compatibility remains based on the core 50-position, 2-row, through-hole solder configuration.
