Parameter Comparison

Engineering Selection Recommendations

The 3-641120-9 serves as the direct active equivalent to the obsolete 641120-9. Both components maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch spacing, mounting configuration, and operating temperature range.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 641120-9 is classified as obsolete with RoHS non-compliant status, while the 3-641120-9 maintains active product status with full RoHS compliance. The contact finish on the post differs between the two parts: the main part uses Tin-Lead while the substitute uses Tin. This difference reflects modern manufacturing standards and environmental regulations.

For new designs and ongoing production requirements, the 3-641120-9 is the appropriate selection due to its active status, RoHS compliance, and continued availability. The electrical and mechanical compatibility between these parts ensures direct substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 3-641120-9 directly replace the 641120-9 in existing applications?

A: Yes. The 3-641120-9 maintains complete electrical and mechanical equivalence to the 641120-9 across all specified parameters including connector type, position count, pitch spacing, mounting type, and operating temperature range. Direct substitution is supported without design modification.

Q: What is the significance of the contact finish difference between these parts?

A: The 641120-9 uses Tin-Lead post finish while the 3-641120-9 uses Tin post finish. Both finishes provide equivalent electrical performance and solder compatibility. The Tin finish on the substitute part reflects current manufacturing standards and environmental compliance requirements.

Q: Why is the 641120-9 listed as obsolete?

A: The 641120-9 has reached end-of-life status in the manufacturer's product portfolio. The 3-641120-9 represents the active equivalent component for continued supply and new design applications.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance status reflects manufacturing process and material sourcing standards rather than electrical or mechanical performance. Both parts meet identical electrical specifications and operating requirements.

Q: Are there packaging differences between these parts?

A: The 641120-9 packaging specification is not provided in the available data. The 3-641120-9 is supplied in Bulk packaging. Confirm packaging requirements with the supplier for specific application needs.

Q: What is the MTA-156 series designation?

A: MTA-156 is the TE Connectivity series designation for rectangular connectors with 0.156" (3.96mm) pitch spacing. Both the 641120-9 and 3-641120-9 belong to this series family.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both connectors are rated for operation across -55°C to 105°C, supporting general purpose and industrial applications within this temperature envelope.
