Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 644460-9 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Number of positions: 9
• Pitch: 0.156" (3.96mm)
• Wire gauge: 18 AWG
• Contact type: Female socket
• Contact finish: Gold at 30.0µin (0.76µm)

Mechanical Parameters:

• Connector type: Receptacle
• Mounting type: Free hanging (in-line)
• Fastening type: Locking ramp
• Cable termination: IDC
• Features: Closed end with polarizing key
• Number of rows: 1

Compliance Parameters:

• RoHS compliance status
• REACH compliance status
• Moisture sensitivity level

The substitute part 3-644460-9 maintains identical electrical and mechanical specifications while differing in product status (active versus obsolete) and packaging configuration (bulk versus standard).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-644460-9 is functionally equivalent to the main part 644460-9 across all electrical, mechanical, and environmental specifications. The primary distinction is product lifecycle status: the main part is classified as obsolete, while the substitute is active.

Selection of the substitute part 3-644460-9 is appropriate for new designs and ongoing procurement requirements. Both parts maintain identical compliance certifications including ROHS3/RoHS compliance and REACH unaffected status. The moisture sensitivity level of 1 (unlimited) applies to both variants, indicating no special storage or handling requirements.

The packaging difference (bulk versus standard) does not affect connector performance or compatibility. This difference reflects distribution and inventory management practices only.

Frequently Asked Questions (FAQ)

Q: Are the 644460-9 and 3-644460-9 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 9 positions, 0.156" pitch, 18 AWG wire gauge, gold contact finish at 30.0µin thickness, and IDC termination method.

Q: What is the significance of the "3-" prefix in part number 3-644460-9?

A: The "3-" prefix indicates a variant designation within the TE Connectivity product line. In this case, it identifies the active production version of the connector, while the base number 644460-9 represents the obsolete variant.

Q: Can I use 3-644460-9 as a direct replacement in existing assemblies designed for 644460-9?

A: Yes. The connectors are mechanically and electrically identical. The mounting type (free hanging in-line), fastening method (locking ramp), and all dimensional specifications are equivalent.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant and REACH unaffected. The main part carries ROHS3 designation while the substitute carries RoHS designation; both meet current regulatory requirements.

Q: Does packaging type affect connector performance?

A: No. The packaging difference (bulk versus standard) is a distribution and inventory consideration only. It does not affect electrical performance, mechanical fit, or environmental compliance.

Q: What wire types are compatible with both connectors?

A: Both connectors accept discrete or ribbon cable at 18 AWG gauge. The IDC termination method is identical for both parts.

Q: Is the polarizing key feature present on both connectors?

A: Yes. Both the 644460-9 and 3-644460-9 include a polarizing key and closed-end design to ensure correct mating orientation.
