TE Connectivity 644042-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644042-7 is a 7-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features gold-plated contacts with a 0.100" (2.54mm) pitch and is configured as a free-hanging, right-angle mounted receptacle with a locking ramp fastening mechanism.

The 644042-7 carries an obsolete product status. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and system integration requirements where this connector type is specified in existing designs or legacy equipment.

Substitute Part Grouping Explanation

Substitution eligibility for the 644042-7 is determined by strict equivalence across the following critical parameters:

Connector Type & Position Count: Receptacle configuration with exactly 7 positions
Pitch & Spacing: 0.100" (2.54mm) pitch, single row
Contact Configuration: Female socket contacts with gold finish at 30.0µin thickness
Termination Method: IDC cable termination for 22 AWG wire
Mounting & Fastening: Free-hanging, right-angle orientation with locking ramp mechanism
Series Designation: MTA-100 series compatibility
Electrical & Environmental Compliance: RoHS compliance and MSL rating

The substitute part 3-644042-7 meets all these parameters identically, differing only in product status (active versus obsolete) and packaging configuration (bulk versus assembled).

Engineering Selection Recommendations

The 3-644042-7 is a direct functional equivalent to the 644042-7 across all electrical, mechanical, and environmental specifications. The primary distinction is product lifecycle status: the 644042-7 is obsolete, while the 3-644042-7 maintains active production status.

Both parts satisfy identical RoHS compliance requirements and carry the same MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. Both are classified under ECCN EAR99 and share the same HTSUS commodity code.

The 3-644042-7 is suitable for direct substitution in applications requiring a 7-position MTA-100 series IDC receptacle connector with 22 AWG wire termination. The active product status of the 3-644042-7 provides assurance of continued availability and manufacturing consistency for new designs, repairs, and system upgrades.

Frequently Asked Questions (FAQ)

Q: Can the 3-644042-7 be used as a direct replacement for the 644042-7?

A: Yes. Both connectors are electrically and mechanically identical across all specified parameters, including pitch, contact configuration, termination method, and mounting orientation. The 3-644042-7 differs only in product status (active) and packaging format (bulk).

Q: What is the significance of the product status difference between obsolete and active?

A: The 644042-7 is no longer manufactured. The 3-644042-7 is in active production, ensuring ongoing availability for procurement, repair, and system integration. For applications requiring long-term component sourcing, the active status of the 3-644042-7 provides supply chain continuity.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts conform to the MTA-100 series standard with identical electrical and mechanical specifications. They accept the same IDC termination tooling and mate with identical connector plugs.

Q: Does the packaging difference affect connector performance?

A: No. Packaging format (assembled versus bulk) does not affect electrical or mechanical performance. Both configurations deliver connectors with identical specifications and quality standards.

Q: What wire gauges and cable types are compatible with these connectors?

A: Both connectors are rated for 22 AWG wire and accept discrete or ribbon cable configurations via IDC termination.

Q: Are these connectors RoHS compliant?

A: Yes. Both the 644042-7 and 3-644042-7 meet RoHS compliance requirements. The 644042-7 is ROHS3 compliant, and the 3-644042-7 is RoHS compliant.
