Mandatory Matching Parameters:

• 56 positions total configuration
• Dual row arrangement (2 rows)
• 0.156" (3.96mm) pitch spacing
• Female gender
• Dual read-out functionality
• Card thickness accommodation range of 0.054" ~ 0.070" (1.37mm ~ 1.78mm) minimum
• Solder termination
• Gold contact finish
• Flush mount, top opening flange with 0.128" (3.25mm) diameter
• Through-hole mounting capability
• Moisture Sensitivity Level 1

Allowable Variations:

• Contact material composition (Phosphor Bronze to Copper Alloy)
• Insulation material type (Glass-filled Polyester to Polyester Thermoplastic)
• Contact finish thickness (30.0µin to 10.0µin)
• Contact type specification (unspecified to Semi Bellows)
• Product status (Obsolete to Active)
• Manufacturer identity
• Operating temperature specification presence
• RoHS compliance status

The substitute parts 305-056-520-202 and 355-056-520-202 satisfy all mandatory matching parameters and represent functionally equivalent alternatives with enhanced compliance certifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

305-056-520-202 Selection Criteria:

The Mercury United Electronics 305-056-520-202 is an active product with ROHS3 compliance and REACH unaffected status. This substitute maintains full electrical and mechanical compatibility with the 3-530657-2 across all critical connector parameters. The green color matches the original specification. The substitute accommodates the same card thickness range and provides identical pitch, position count, and dual-row configuration. Operating temperature specification of -40°C to 105°C is provided for this active product. The contact finish thickness of 10.0µin meets gold plating requirements, though at a reduced thickness compared to the original 30.0µin specification.

355-056-520-202 Selection Criteria:

The Mercury United Electronics 355-056-520-202 is an active product with ROHS3 compliance and REACH unaffected status. This substitute maintains full electrical and mechanical compatibility with the 3-530657-2 across all critical connector parameters. The primary distinction is the black color insulation versus the green color of the original part. All other specifications, including pitch, position count, dual-row configuration, card thickness accommodation, and solder termination, remain identical. Operating temperature specification of -40°C to 105°C is provided. The contact finish thickness of 10.0µin meets gold plating requirements.

Compliance Advantage:

Both substitute parts offer enhanced regulatory compliance compared to the obsolete 3-530657-2. The ROHS3 compliance status and REACH unaffected designation of the substitute parts provide advantages for applications subject to environmental and hazardous substance regulations. The active product status of both substitutes ensures ongoing availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the 305-056-520-202 or 355-056-520-202 be used as direct replacements for the 3-530657-2?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications across all critical parameters: 56 positions, dual rows, 0.156" pitch, female gender, dual read-out, solder termination, gold contact finish, and compatible card thickness range. The substitutes accommodate the same through-hole mounting and flange configuration.

Q: What is the difference between the 305-056-520-202 and 355-056-520-202?

A: The primary difference is the insulation color. The 305-056-520-202 features green insulation matching the original 3-530657-2, while the 355-056-520-202 features black insulation. All other electrical and mechanical specifications are identical between these two substitutes.

Q: Does the reduced contact finish thickness on the substitute parts affect compatibility?

A: The substitute parts feature 10.0µin (0.25µm) gold contact finish thickness compared to 30.0µin (0.76µm) on the original part. Both thicknesses provide gold plating for the connector contacts. The reduced thickness on the active substitute products reflects current manufacturing standards while maintaining the gold contact finish specification.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 305-056-520-202 and 355-056-520-202 carry ROHS3 compliance status, whereas the original 3-530657-2 is RoHS non-compliant. This represents an improvement in regulatory compliance for applications subject to RoHS requirements.

Q: What is the operating temperature range for the substitute parts?

A: Both substitute parts specify an operating temperature range of -40°C to 105°C. The original 3-530657-2 does not specify an operating temperature range.

Q: Are the substitute parts available in stock?

A: Inventory availability is subject to current stock levels. The 305-056-520-202 has 847 pieces available, and the 355-056-520-202 has 773 pieces available as new original stock.

Q: What is the difference in contact material between the original and substitute parts?

A: The original 3-530657-2 uses Phosphor Bronze contacts, while the substitute parts use Copper Alloy contacts. Both materials are suitable for the connector application and maintain electrical performance specifications.

Q: Can I mix the 305-056-520-202 and 355-056-520-202 in the same application?

A: Yes. Both parts are electrically and mechanically equivalent. The selection between them depends on the color requirement for your application. The 305-056-520-202 provides green insulation, and the 355-056-520-202 provides black insulation.
