Parameter Comparison

Engineering Selection Recommendations

The substitute part 4-644759-0 is functionally and mechanically equivalent to the obsolete 1-644759-0 across all critical electrical and mechanical parameters. The primary differences are:

Product Status: The substitute part maintains active product status, ensuring continued availability and manufacturer support. The main part is classified as obsolete and subject to discontinuation.

Compliance Certifications: The substitute part is ROHS3 compliant and carries defined REACH status (REACH Unaffected), whereas the main part is RoHS non-compliant with undefined REACH status. This compliance improvement aligns with current regulatory requirements for electronic components in industrial and general purpose applications.

Contact Finish - Post: The substitute part features Tin finish on the post termination, replacing the Tin-Lead finish of the main part. This represents a lead-free upgrade consistent with RoHS3 compliance requirements and does not affect electrical or mechanical compatibility.

Inventory Availability: The substitute part (4-644759-0) has 1,073 pieces in stock compared to 891 pieces for the main part, providing improved procurement availability.

For new designs and procurement of replacement components, the 4-644759-0 substitute part is the appropriate selection due to active product status, regulatory compliance, and identical functional specifications.

Frequently Asked Questions (FAQ)

Q: Are the 1-644759-0 and 4-644759-0 parts mechanically interchangeable?

A: Yes. Both parts are identical in all mechanical dimensions, including contact length, insulation height, pitch spacing, and shrouding configuration. They are direct mechanical substitutes suitable for board-to-cable/wire connections in through-hole applications.

Q: What is the difference between the Tin-Lead and Tin contact finishes on the post termination?

A: The main part (1-644759-0) uses Tin-Lead finish, while the substitute (4-644759-0) uses Tin finish. The Tin finish represents a lead-free upgrade that complies with RoHS3 regulations. Both finishes provide equivalent solderability and electrical performance for solder termination applications.

Q: Can the 4-644759-0 be used as a direct replacement in existing designs using 1-644759-0?

A: Yes. The substitute part maintains identical electrical ratings (600VAC), operating temperature range (-55°C to 105°C), and all mechanical specifications. The lead-free Tin finish on the post termination is compatible with standard solder processes and does not require design modifications.

Q: Why is the main part classified as obsolete?

A: The 1-644759-0 is classified as obsolete by the manufacturer. The 4-644759-0 represents the active equivalent in the MTA-156 series, offering improved compliance certifications and continued product support.

Q: What is the significance of the RoHS3 compliance on the substitute part?

A: RoHS3 compliance indicates that the substitute part (4-644759-0) meets current European Union Restriction of Hazardous Substances regulations, restricting the use of lead and other hazardous materials. This compliance is required for components used in many industrial and consumer applications and is not present in the obsolete main part.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts maintain identical voltage ratings (600VAC), current ratings (varies by wire gauge), operating temperature ranges (-55°C to 105°C), and contact material specifications (Copper Alloy with Gold mating finish). Electrical performance is equivalent.

Q: What packaging options are available for the substitute part?

A: The substitute part 4-644759-0 is supplied in Bulk packaging. The main part packaging specification was not provided in the technical documentation.

Q: Is the 10-position, 0.156" pitch configuration standard for this connector series?

A: Yes. The MTA-156 series is standardized around 0.156" (3.96mm) pitch spacing. The 10-position configuration is one of several available position counts within this series, all maintaining identical pitch and mechanical compatibility.
