Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 641238-9 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (9)
• Contact pitch (0.100" / 2.54mm)
• Wire gauge compatibility (24 AWG)
• Contact finish specification (Gold, 30.0µin thickness)

Mechanical Parameters:

• Mounting configuration (Free Hanging, In-Line, Right Angle)
• Fastening mechanism (Locking Ramp)
• Cable termination method (IDC)
• Closed-end design
• Single-row configuration

Environmental & Compliance Parameters:

• Moisture Sensitivity Level (MSL 1 - Unlimited)
• Series compatibility (MTA-100)

The substitute part 3-641238-9 maintains identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The part 641238-9 is classified as obsolete and presents supply chain constraints for new designs and system maintenance. The direct substitute 3-641238-9 provides complete functional and mechanical equivalence while offering the following advantages:

Product Status: The substitute part maintains active product status with confirmed inventory availability (1593 pieces), ensuring reliable procurement for both new production and field replacement applications.

Compliance Certification: The substitute part 3-641238-9 is RoHS compliant, whereas the original part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations and environmental compliance requirements.

Electrical & Mechanical Compatibility: All electrical parameters, mechanical specifications, and termination methods are identical between the main part and substitute. The 9-position, 0.100" pitch IDC receptacle configuration, gold contact finish, and locking ramp fastening mechanism remain unchanged.

Packaging Consideration: The substitute part is supplied in bulk packaging, which may differ from the original part's packaging specification. This does not affect functional compatibility but should be considered for inventory management and component handling procedures.

For applications requiring the 641238-9, the 3-641238-9 substitute provides direct replacement capability with enhanced compliance status and active supply chain support.

Frequently Asked Questions (FAQ)

Q: Can the 3-641238-9 directly replace the 641238-9 in existing designs?

A: Yes. The 3-641238-9 is a direct substitute with identical electrical and mechanical specifications. All parameters including connector type, contact configuration, pitch, wire gauge, termination method, and mounting type are equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and RoHS compliance. The 641238-9 is obsolete and RoHS non-compliant, while the 3-641238-9 is active and RoHS compliant. All functional specifications remain identical.

Q: Are there any compatibility concerns when substituting the 3-641238-9 for the 641238-9?

A: No compatibility concerns exist. Both parts are from the TE Connectivity MTA-100 series with identical contact pitch (0.100"), position count (9), and IDC termination specifications. The connectors are mechanically and electrically interchangeable.

Q: Does the packaging difference affect the component's performance?

A: No. The packaging difference (bulk versus original packaging) does not affect electrical or mechanical performance. The connector itself remains identical. Packaging selection should be based on procurement and inventory management requirements.

Q: What wire gauges are compatible with these connectors?

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

Q: Is the RoHS compliance status important for my application?

A: RoHS compliance status depends on your application requirements and regulatory environment. If your design or market requires RoHS compliance, the 3-641238-9 substitute meets this requirement, whereas the original 641238-9 does not.

Q: Can these connectors be used in right-angle and in-line configurations?

A: Yes. Both the 641238-9 and 3-641238-9 support free-hanging mounting in both right-angle and in-line orientations.
