Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4-644574-3 is determined by strict equivalence across the following critical parameters: connector type (rectangular receptacle), number of positions (13), pitch spacing (0.100"), contact type (female socket), cable termination method (IDC), wire gauge (24 AWG), contact finish (tin), mounting configuration (free hanging in-line and right angle), and series designation (MTA-100). Parts meeting all these criteria are classified as direct functional equivalents. The primary distinction between the main part and its substitute relates to product status and packaging configuration, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The 4-644312-3 serves as a direct functional substitute for the obsolete 4-644574-3. Both parts are manufactured by TE Connectivity within the MTA-100 series and share identical electrical and mechanical specifications across all critical parameters. The substitute part maintains active product status, ensuring ongoing availability and supply chain reliability. Both parts carry RoHS compliance certification and identical MSL ratings, confirming environmental and regulatory equivalence. The 4-644312-3 is supplied in bulk packaging and maintains higher inventory levels, supporting procurement efficiency. Selection of the substitute part introduces no compatibility risk for applications currently utilizing the 4-644574-3, as all contact configurations, termination methods, and mechanical interfaces remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the 4-644312-3 be used as a direct replacement for the 4-644574-3 in existing designs?

A: Yes. Both parts are identical in electrical and mechanical specifications. The 4-644312-3 maintains the same 13-position configuration, 0.100" pitch, IDC termination method, 24 AWG wire gauge, tin contact finish, and mounting type. No design modifications are required.

Q: What is the primary difference between these two parts?

A: The 4-644574-3 is classified as obsolete, while the 4-644312-3 maintains active product status. The substitute part is supplied in bulk packaging. All functional parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the 4-644574-3 and 4-644312-3 carry RoHS compliance certification and are suitable for applications requiring environmental regulatory adherence.

Q: Does the packaging difference affect connector performance?

A: No. Packaging configuration does not impact electrical or mechanical performance. The bulk packaging of the 4-644312-3 affects only procurement and logistics considerations.

Q: What wire gauges are compatible with these connectors?

A: Both connectors are specified for 24 AWG wire. The IDC termination method accommodates discrete or ribbon cable configurations at this gauge.

Q: Are the contact finishes identical between the two parts?

A: Yes. Both parts feature tin contact finish with identical thickness specifications of 80.0µin (2.03µm), ensuring equivalent electrical conductivity and corrosion resistance.

Q: What is the pitch specification for these connectors?

A: Both parts feature a 0.100" (2.54mm) pitch, which determines the spacing between individual contact positions and ensures mechanical compatibility with mating connectors.
