Engineering Selection Recommendations

The 1-644038-4 is classified as obsolete and is RoHS non-compliant. The direct substitute part 4-644038-4 provides identical electrical and mechanical functionality while offering two significant advantages:

Product Status: The 4-644038-4 maintains active product status, ensuring continued availability and manufacturer support for future procurement cycles.

Regulatory Compliance: The 4-644038-4 is RoHS compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution. This compliance status is critical for applications subject to RoHS directives and similar regulatory frameworks.

All other parameters remain functionally equivalent between the two parts, including connector geometry, contact specifications, termination method, and environmental ratings. Selection of the 4-644038-4 is appropriate for new designs and replacement applications requiring current regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 4-644038-4 be used as a direct replacement for the 1-644038-4?

A: Yes. The 4-644038-4 is electrically and mechanically equivalent to the 1-644038-4 across all functional parameters, including connector type, position count, pitch, contact specifications, mounting configuration, and termination method. Both parts are MTA-100 series 14-position receptacles with identical gold-plated contact finishes and IDC termination capability.

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

A: The primary differences are product status and regulatory compliance. The 1-644038-4 is obsolete and RoHS non-compliant, while the 4-644038-4 is an active product that meets RoHS compliance requirements. Functionally, both connectors are identical.

Q: Are there any compatibility concerns when substituting the 4-644038-4 for the 1-644038-4?

A: No compatibility concerns exist. Both parts share identical specifications for connector type, contact type, position count, pitch, mounting type, fastening mechanism, cable termination method, wire gauge, and contact finish. They are fully interchangeable in applications designed for the MTA-100 series 14-position receptacle connector.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both parts deliver identical electrical characteristics and contact performance.

Q: What wire gauges are compatible with these connectors?

A: Both the 1-644038-4 and 4-644038-4 are rated for 22 AWG wire. They support both discrete wire and ribbon cable termination using the IDC (Insulation Displacement Contact) method.

Q: Can these connectors be used with ribbon cable?

A: Yes. Both connectors support ribbon cable termination in addition to discrete wire configurations, as specified by the IDC termination method and closed-end design.

Q: What is the pitch specification for these connectors?

A: Both connectors feature a 0.100-inch (2.54mm) pitch, which is the standard spacing between contact positions in the MTA-100 series.

Q: Are there any environmental or storage considerations for these parts?

A: Both parts carry a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
