The substitute part 3-644617-8 maintains full equivalence across all critical electrical and mechanical parameters. The primary distinction is product status: 3-644617-8 is active and currently available, whereas 644613-8 is obsolete. Both parts are manufactured by TE Connectivity AMP Connectors within the MTA-156 series and satisfy identical application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 3-644617-8 is the direct substitute for the obsolete 644613-8. Both parts are manufactured by TE Connectivity AMP Connectors within the MTA-156 series and maintain identical electrical and mechanical specifications across all critical parameters including pitch, position count, voltage rating, operating temperature range, and flammability rating.

The primary distinction between these parts is product status: 644613-8 is obsolete, while 3-644617-8 is active and currently available. Both parts are ROHS3 compliant and carry identical compliance certifications. The contact finish differs slightly (Tin-Lead versus Tin), which represents a compatible variation within the same connector family and does not affect functional equivalence.

For new designs and ongoing production requirements, 3-644617-8 is the appropriate selection due to its active status and guaranteed availability. For field service applications requiring replacement of existing 644613-8 connectors, 3-644617-8 provides direct functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can 3-644617-8 be used as a direct replacement for 644613-8 in existing designs?

A: Yes. Both connectors are electrically and mechanically equivalent. They share identical pitch (0.156"), position count (8), voltage rating (600VAC), operating temperature range (-55°C ~ 105°C), mounting type (through-hole right-angle), and termination method (solder). Both are ROHS3 compliant and UL94 V-0 rated.

Q: What is the difference between the contact finishes of these two parts?

A: The 644613-8 features Tin-Lead contact finish, while the 3-644617-8 features Tin contact finish. Both finishes are applied at 150.0µin (3.81µm) thickness and are compatible for the same applications. The Tin finish on 3-644617-8 reflects current manufacturing standards and RoHS compliance requirements.

Q: Why is 644613-8 listed as obsolete?

A: The 644613-8 is obsolete due to product lifecycle management by TE Connectivity. The 3-644617-8 represents the current active equivalent within the MTA-156 series and is the recommended selection for all new applications and ongoing procurement.

Q: Are there packaging differences between these parts?

A: The 644613-8 packaging information is not specified in available data. The 3-644617-8 is supplied in Bulk packaging. Both parts are available in new original condition with documented inventory levels.

Q: Do these connectors support the same current ratings?

A: Yes. Both parts carry identical current rating specifications: Current Rating (Amps) varies by wire gauge. The current capacity is determined by the wire gauge used in the mating cable/wire assembly, not by the connector itself.

Q: Are both parts suitable for industrial applications?

A: Yes. Both 644613-8 and 3-644617-8 are rated for general purpose and industrial applications. They meet UL94 V-0 flammability requirements and operate across the -55°C ~ 105°C temperature range suitable for industrial environments.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life with no special moisture control requirements during storage or handling.
