Substitute Part Grouping Explanation
Substitution of the 1-644540-0 is determined by strict equivalence across the following critical parameters: connector type (receptacle), number of positions (10), pitch spacing (0.100"), number of rows (1), contact type (female socket), cable termination method (IDC), wire gauge (22 AWG), mounting configuration (free hanging in-line and right angle), fastening mechanism (locking ramp), contact finish thickness (80.0µin), and feed-through feature. The substitute part 4-644540-0 maintains identical specifications across all these parameters, with the primary distinction being contact finish composition and product status classification.

Engineering Selection Recommendations
The 4-644540-0 serves as the direct active equivalent to the obsolete 1-644540-0. Both parts maintain identical mechanical and electrical specifications within the MTA-100 series, ensuring form, fit, and function compatibility. The primary distinction is product status: the 1-644540-0 is classified as obsolete, while the 4-644540-0 is active and available in production quantities. Additionally, the 4-644540-0 achieves ROHS3 compliance, whereas the 1-644540-0 is RoHS non-compliant. The contact finish differs between tin-lead (1-644540-0) and tin (4-644540-0), both maintaining identical thickness specifications. For new designs and ongoing procurement, the 4-644540-0 is the appropriate selection based on active product status and regulatory compliance.
Frequently Asked Questions (FAQ)
Q: Are the 1-644540-0 and 4-644540-0 mechanically interchangeable?
A: Yes. Both connectors share identical mechanical specifications: 10 positions, 0.100" pitch, single row configuration, female socket contact type, free hanging in-line and right angle mounting, and locking ramp fastening. Physical dimensions and mounting interfaces are equivalent.
Q: What is the functional difference between tin-lead and tin contact finishes?
A: Both contact finishes are applied at 80.0µin (2.03µm) thickness. The tin-lead finish in the 1-644540-0 and the tin finish in the 4-644540-0 differ in composition. Both finishes maintain the same contact finish thickness specification.
Q: Why is the 1-644540-0 classified as obsolete?
A: The 1-644540-0 has reached end-of-life status within TE Connectivity's product portfolio. The 4-644540-0 represents the active continuation within the MTA-100 series.
Q: Does RoHS compliance affect electrical performance?
A: RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts maintain identical electrical specifications. The 4-644540-0 achieves ROHS3 compliance, while the 1-644540-0 does not.
Q: Can the 4-644540-0 be used in applications originally designed for the 1-644540-0?
A: Yes. The 4-644540-0 maintains form, fit, and function equivalence with the 1-644540-0 across all specified parameters: connector type, position count, pitch, row configuration, contact type, termination method, wire gauge, mounting type, fastening mechanism, and feed-through feature.
Q: What is the packaging difference between these parts?
A: The 1-644540-0 packaging specification is not provided. The 4-644540-0 is supplied in bulk packaging.
Q: Are both parts suitable for discrete or ribbon cable applications?
A: Yes. Both the 1-644540-0 and 4-644540-0 support discrete or ribbon cable wire types at 22 AWG gauge with IDC termination.
