Substitute Part Grouping Explanation

Substitution between the main part 647127-5 and the alternative part 2-647127-5 is based on strict equivalence across all critical electrical and mechanical parameters. Both components share identical specifications for connector type, contact configuration, pitch spacing, mounting methodology, shrouding design, termination approach, voltage rating, temperature range, and flammability compliance. The primary distinction between these parts is product status and contact finish composition. The main part 647127-5 carries obsolete status with tin-lead contact finish, while the substitute part 2-647127-5 maintains active product status with tin contact finish. Both finishes meet the specified 150.0µin (3.81µm) thickness requirement and are applied to both mating and post contact surfaces. The substitute part is functionally interchangeable in all applications where the main part was originally specified, provided that the tin contact finish is acceptable for the intended circuit environment.

Engineering Selection Recommendations

The substitute part 2-647127-5 is the direct equivalent for the obsolete 647127-5 connector header. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 647127-5 carries obsolete designation, indicating discontinued manufacturing and limited availability. The substitute part 2-647127-5 maintains active product status, ensuring ongoing supply chain support and manufacturing consistency.

Compliance and Certifications: Both parts maintain identical compliance profiles including UL94 V-0 flammability rating, RoHS compliance, and EAR99 export classification. The substitute part carries RoHS Compliant designation while the main part carries ROHS3 Compliant designation; both satisfy current regulatory requirements.

Electrical and Mechanical Equivalence: All critical parameters including voltage rating (600VAC), operating temperature range (-55°C ~ 105°C), contact configuration, pitch spacing (0.156"), mounting methodology, and termination approach are identical between the two parts.

Contact Finish Consideration: The primary technical difference is the contact finish composition. The main part uses tin-lead finish while the substitute uses tin finish. Both finishes are applied at the specified 150.0µin (3.81µm) thickness and are suitable for general purpose and industrial applications. The tin finish of the substitute part aligns with contemporary lead-free manufacturing standards.

For new designs and ongoing procurement, the substitute part 2-647127-5 is the appropriate selection due to active product status and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Are the 647127-5 and 2-647127-5 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including shrouding design (shrouded 4-wall), mounting type (through-hole), contact dimensions, insulation height, and overall form factor. They are directly interchangeable in PCB layouts and cable assemblies.

Q: What is the difference between tin-lead and tin contact finishes in these connectors?

A: The main part 647127-5 uses tin-lead contact finish, while the substitute part 2-647127-5 uses tin contact finish. Both finishes are applied at 150.0µin (3.81µm) thickness. Tin finish is the contemporary standard and aligns with lead-free manufacturing initiatives. Both finishes provide equivalent electrical performance and corrosion resistance for the specified operating temperature range.

Q: Can I use the 2-647127-5 as a direct replacement for the 647127-5 in existing assemblies?

A: Yes. The substitute part 2-647127-5 is functionally equivalent across all electrical and mechanical parameters. It can be used as a direct replacement in existing designs without circuit modification or re-qualification, provided that the tin contact finish is acceptable for your application environment.

Q: Why is the main part 647127-5 listed as obsolete?

A: The 647127-5 has been discontinued by the manufacturer. The substitute part 2-647127-5 represents the active product line continuation within the MTA-156 series and is the recommended selection for new procurement and design work.

Q: What is the voltage and temperature rating for these connectors?

A: Both the 647127-5 and 2-647127-5 are rated for 600VAC operation and support an operating temperature range of -55°C to 105°C. These ratings apply to the connector body and contact system.

Q: Are there packaging differences between these two parts?

A: The main part 647127-5 packaging is not specified in the available data. The substitute part 2-647127-5 is supplied in bulk packaging. Confirm packaging requirements with your procurement department for order fulfillment.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. The main part 647127-5 is ROHS3 Compliant, and the substitute part 2-647127-5 is RoHS Compliant. Both meet current regulatory requirements for restricted substances.

Q: What is the current rating for these connectors?

A: The current rating varies by wire gauge for both parts. Consult the connector datasheet and wire gauge specifications to determine the maximum current capacity for your specific application.
