Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-530666-4 with Mercury United Electronics 357-030-520-201 is based on alignment of the following critical electrical and mechanical parameters:

Matching Parameters:

• Number of Positions: 30
• Pitch: 0.156" (3.96mm)
• Gender: Female
• Card Type: Non Specified - Dual Edge
• Number of Rows: 2
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish: Gold
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99
• HTSUS Code: 8536.69.4040

These parameters define the functional and mechanical compatibility required for direct substitution in card edge connector applications. Both parts accommodate the same card thickness range and provide equivalent electrical performance through gold-plated contact surfaces.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 2-530666-4 is the primary specification for applications where RoHS non-compliant components are acceptable and REACH-affected materials are permitted. This part provides an extended operating temperature range of -55°C to 105°C and features phosphor bronze contacts with thicker gold plating (30.0µin).

Mercury United Electronics 357-030-520-201 serves as a functional substitute when ROHS3 compliance and REACH unaffected status are required. This part operates within the -40°C to 105°C temperature range and incorporates semi-bellows contact design with copper alloy base material. The substitute is suitable for applications where regulatory compliance takes precedence and the minimum operating temperature requirement does not extend below -40°C.

Both parts maintain Active product status and share identical electrical and mechanical interface parameters. Selection between these parts depends on compliance requirements, operating temperature specifications, and packaging format needs (Tray versus Bulk).

Frequently Asked Questions (FAQ)

Q: Can Mercury United Electronics 357-030-520-201 replace TE Connectivity 2-530666-4 in all applications?

A: Substitution is valid for applications where the operating temperature range of -40°C to 105°C is acceptable. If the application requires operation below -40°C, the TE Connectivity part with its -55°C minimum rating is required. Both parts provide identical pitch, position count, and through-hole solder termination.

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

A: The TE Connectivity 2-530666-4 features 30.0µin (0.76µm) gold plating, while the Mercury United Electronics 357-030-520-201 features 10.0µin (0.25µm) gold plating. Both thicknesses provide adequate gold contact surface for electrical performance in card edge connector applications.

Q: Are there packaging differences between these parts?

A: Yes. The TE Connectivity 2-530666-4 is supplied in Tray packaging, while the Mercury United Electronics 357-030-520-201 is supplied in Bulk packaging. Packaging format selection depends on assembly line requirements and inventory management practices.

Q: What compliance certifications differ between these parts?

A: The TE Connectivity 2-530666-4 is RoHS non-compliant and REACH Affected. The Mercury United Electronics 357-030-520-201 is ROHS3 Compliant and REACH Unaffected. Applications subject to RoHS3 or REACH regulations must use the Mercury United Electronics part.

Q: Do both parts accommodate the same card thickness range?

A: Both parts accommodate overlapping card thickness ranges. The TE Connectivity part accepts 0.055" to 0.070" (1.40mm to 1.78mm), while the Mercury United Electronics part accepts 0.054" to 0.070" (1.37mm to 1.78mm). The Mercury part accommodates slightly thinner cards at the lower end.

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

A: The TE Connectivity 2-530666-4 uses phosphor bronze contacts, while the Mercury United Electronics 357-030-520-201 uses copper alloy contacts with semi-bellows design. Both materials provide suitable electrical conductivity and mechanical retention for card edge connector applications.
