Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 531433-4 is determined by the following critical parameters:

Position and Pitch Compatibility: The substitute part must maintain 44 positions with 0.156" (3.96mm) pitch to ensure mechanical and electrical compatibility with mating components.

Connector Configuration: Dual edge, female gender, and 2-row configuration must be preserved to maintain form factor and functional compatibility.

Card Thickness Tolerance: The substitute part must accommodate card thickness within the specified range to ensure proper contact engagement and retention.

Termination Method: Solder termination is required for PCB integration compatibility.

Contact Finish: Gold plating is specified for corrosion resistance and electrical performance.

The Mercury United Electronics, Inc. part number 307-044-524-201 meets all critical substitution parameters and is classified as an equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (TE Connectivity 531433-4): This connector is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material sourcing is permissible. The part is in active product status with established supply availability.

Substitute Part (Mercury 307-044-524-201): This connector is suitable for applications requiring RoHS3 compliance and REACH-unaffected material sourcing. The part is in active product status and provides equivalent electrical and mechanical functionality. The substitute part features a lower contact finish thickness (10.0µin versus 30.0µin) and copper alloy contact material compared to the primary part, which remains within acceptable parameters for the specified connector category.

Selection between these parts is determined by regulatory compliance requirements and material sourcing constraints specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the Mercury 307-044-524-201 be used as a direct replacement for the TE Connectivity 531433-4?

A: Yes. Both connectors share identical position count (44), pitch (0.156"), gender (female), row configuration (2), mounting type (through hole), and termination method (solder). Card thickness tolerance ranges are compatible. The connectors are mechanically and electrically interchangeable.

Q: What is the difference in contact finish thickness between these parts?

A: The TE Connectivity 531433-4 features 30.0µin (0.76µm) gold plating, while the Mercury 307-044-524-201 features 10.0µin (0.25µm) gold plating. Both thicknesses are within industry standards for card edge connectors and provide adequate corrosion protection and electrical conductivity for the specified application category.

Q: Are there compliance differences between these parts?

A: Yes. The TE Connectivity 531433-4 is RoHS non-compliant and REACH-affected. The Mercury 307-044-524-201 is ROHS3 compliant and REACH-unaffected. Selection depends on regulatory requirements applicable to the end application and geographic market.

Q: What is the difference in contact material?

A: The TE Connectivity 531433-4 uses phosphor bronze contacts, while the Mercury 307-044-524-201 uses copper alloy contacts. Both materials are suitable for card edge connector applications and provide equivalent electrical performance within the specified connector category.

Q: Are the card thickness tolerances identical?

A: The tolerances are nearly identical with minimal variation. TE Connectivity specifies 0.055" ~ 0.070" (1.40mm ~ 1.78mm), while Mercury specifies 0.054" ~ 0.070" (1.37mm ~ 1.78mm). Both ranges accommodate standard PCB thicknesses and are compatible for substitution purposes.

Q: What packaging differences exist between these parts?

A: The TE Connectivity 531433-4 is supplied in tray packaging, while the Mercury 307-044-524-201 is supplied in bulk packaging. Packaging format does not affect connector functionality or compatibility.
