TE Connectivity AMP Connectors 1438761-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1438761-6 is a 22-position rectangular connector housing designed for plug applications with a 2.50mm pitch. This connector operates across a temperature range of -30°C to 105°C and features a latch lock fastening mechanism with a lock plate. The part is currently in Active product status with 1006 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design flexibility permits alternative configurations that maintain electrical and mechanical compatibility within the specified parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1438761-6 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug
• Contact Type: Female Socket
• Number of Positions: 22
• Pitch: 0.098" (2.50mm)
• Number of Rows: 2
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Features: Lock Plate
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Allowable Variation Parameters:

• Color: Gray or Black
• Insulation Material: Thermoplastic or equivalent
• Operating Temperature Range: -30°C ~ 105°C or greater
• Series designation: Multi-Lock or unspecified
• Product Status: Active or Last Time Buy

The substitute part 1438759-2 maintains full electrical and mechanical compatibility with the 1438761-6 across all mandatory parameters. The primary difference is the housing color (Black versus Gray), which does not affect functional performance or connector interface specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: 1438761-6

The 1438761-6 is the recommended primary choice for new designs and ongoing production. This part maintains Active product status, ensuring long-term availability and supply chain stability. It is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The part is currently in stock with 1006 units available.

Substitute Selection: 1438759-2

The 1438759-2 serves as a direct functional equivalent when the 1438761-6 becomes unavailable or when design specifications permit housing color variation. This part is designated as Last Time Buy, indicating limited future availability. It maintains identical electrical and mechanical specifications across all critical parameters and carries the same compliance certifications (REACH Unaffected, MSL 1). Current inventory of 1153 units exceeds that of the primary part.

Selection Criteria:

• Use 1438761-6 for new designs and standard production runs
• Use 1438759-2 only when 1438761-6 is unavailable or when housing color (Black) is acceptable for the application
• Both parts are suitable for operating environments from -30°C to 105°C
• Both parts support crimp termination with identical contact interface specifications
• Housing color difference does not affect electrical performance or mechanical fit

Frequently Asked Questions (FAQ)

Q: Can 1438759-2 be used as a direct replacement for 1438761-6 in existing assemblies?

A: Yes. The 1438759-2 is electrically and mechanically equivalent to the 1438761-6 across all functional parameters. The only difference is housing color (Black versus Gray). Compatibility is maintained for all connector interface specifications, pitch, position count, and termination methods.

Q: What is the significance of the "Last Time Buy" status for 1438759-2?

A: Last Time Buy status indicates that TE Connectivity has announced end-of-life for this part. Future availability is limited, and no new production is planned. Existing inventory (1153 units) represents the final supply. For long-term applications, the Active-status 1438761-6 is the preferred choice.

Q: Are there any temperature or environmental differences between these parts?

A: The 1438761-6 specifies an operating temperature range of -30°C to 105°C. The 1438759-2 does not specify this parameter in available documentation. Both parts carry identical Moisture Sensitivity Level (MSL 1 - Unlimited) and REACH Unaffected status, indicating equivalent environmental performance within standard operating conditions.

Q: Can these connectors be intermixed in the same assembly?

A: Yes. Both parts are mechanically and electrically compatible. They can be used in the same assembly without affecting connector interface performance. However, housing color variation may be a consideration for visual identification or aesthetic requirements.

Q: What does "Contacts Not Included" mean for these parts?

A: Both the 1438761-6 and 1438759-2 are connector housings only. Crimp contacts must be sourced separately and inserted into the housing. The housing accommodates 22 contacts in a 2-row configuration with 0.098" (2.50mm) pitch spacing.

Q: Are both parts RoHS and REACH compliant?

A: The 1438761-6 is explicitly ROHS3 compliant and REACH unaffected. The 1438759-2 is REACH unaffected. Both parts meet current regulatory requirements for electronic component use in regulated markets.

Q: What is the difference between the base product numbers 1438761 and 1438759?

A: The base product numbers indicate different product families within the TE Connectivity AMP Connectors Multi-Lock series. The suffix numbers (-6 and -2) denote specific variants, primarily distinguished by housing color. Both base families share identical connector specifications and are cross-compatible.
