Key Parameters

Substitute Part Grouping Explanation

The 307-056-500-201 qualifies as a direct substitute based on the following critical parameters:

• Position Count & Pitch: Both parts maintain 56 positions with 0.156" (3.96mm) pitch spacing, ensuring mechanical and electrical compatibility with existing card edge interfaces.
• Gender & Configuration: Both are female connectors with dual edge, dual read-out configuration.
• Contact Material & Finish: Both feature gold-plated contacts on copper-based materials, maintaining electrical performance characteristics.
• Operating Temperature: Identical temperature range of -40°C ~ 105°C supports equivalent thermal performance.
• Compliance: Both are ROHS3 compliant with REACH unaffected status, meeting regulatory requirements.
• Insulation Material: Both use polyester thermoplastic insulation.

The primary distinction is product status: 307-056-500-201 is active with current manufacturing support, whereas 307-056-502-201 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The 307-056-500-201 is the direct substitute for the obsolete 307-056-502-201. Both parts maintain identical electrical and mechanical specifications for the critical interface parameters: 56-position dual edge configuration, 0.156" pitch, female gender, and gold contact finish.

The substitute part is currently in active production status with documented inventory availability, ensuring supply chain reliability. Both parts meet ROHS3 compliance and REACH regulatory requirements, supporting equivalent environmental and safety standards.

The card thickness tolerance on the substitute part (0.054" ~ 0.070") encompasses the main part specification (0.062"), confirming mechanical compatibility with existing card edge interfaces. The substitute provides documented contact finish thickness (10.0µin) and semi-bellows contact type, offering enhanced specification clarity for design verification purposes.

Frequently Asked Questions (FAQ)

Q: Are these connectors mechanically interchangeable?

A: Yes. Both the 307-056-502-201 and 307-056-500-201 maintain identical position count (56), pitch spacing (0.156"), dual edge configuration, and female gender. The substitute's card thickness tolerance (0.054" ~ 0.070") encompasses the main part specification (0.062"), confirming mechanical compatibility.

Q: What is the primary reason for substitution?

A: The 307-056-502-201 is classified as obsolete. The 307-056-500-201 is an active equivalent that maintains all critical electrical and mechanical parameters while offering current manufacturing support and documented availability.

Q: Are the contact materials equivalent?

A: Both parts feature gold-plated contacts on copper-based materials. The main part specifies copper, nickel, and tin alloy composition, while the substitute specifies copper alloy. Both configurations support equivalent electrical performance for card edge connector applications. The substitute provides documented contact finish thickness of 10.0µin (0.25µm).

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 307-056-502-201 and 307-056-500-201 are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What is the difference in termination specifications?

A: The main part does not specify termination details. The substitute is documented as through-hole mounted with solder eyelet termination, providing enhanced specification clarity for PCB assembly and design integration.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the identical temperature range of -40°C ~ 105°C, supporting equivalent thermal performance in target applications.
