TE Connectivity 776128-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 776128-6 is a 2-position rectangular connector plug housing from the Multi-Lock series, designed for crimp contact termination with a 0.138" (3.50mm) pitch. This gray polybutylene terephthalate (PBT) housing operates as a free-hanging in-line connector with latch lock fastening. The part is currently active in production and ROHS3 compliant.

Substitute parts are necessary when specific color requirements, inventory availability, or compliance certifications differ from the primary part number, while maintaining identical electrical and mechanical functionality.

Substitute Part Grouping Explanation

All substitute parts maintain identical electrical and mechanical specifications as the primary part 776128-6. Substitution is determined by the following parameters that remain constant across all equivalent parts:

Connector type: Plug
Contact type: Female Socket
Number of positions: 2
Pitch: 0.138" (3.50mm)
Number of rows: 1
Mounting type: Free Hanging (In-Line)
Contact termination: Crimp
Fastening type: Latch Lock
Insulation material: Polybutylene Terephthalate (PBT)
Series: Multi-Lock
Moisture sensitivity level: 1 (Unlimited)

The primary variable differentiating substitute parts is housing color. All substitute parts are functionally interchangeable with 776128-6 when color specification is not a design constraint.

Engineering Selection Recommendations

All substitute parts listed are active production components from TE Connectivity AMP Connectors and maintain full functional compatibility with 776128-6 across all electrical and mechanical parameters.

For applications requiring ROHS3 compliance specifically, parts 776128-6, 174463-2, 282365-1, and 368538-1 are suitable selections. Parts 174463-1 and 174463-7 carry RoHS Compliant status without the ROHS3 designation.

Inventory availability varies across substitute options. Part 174463-2 (black) offers the highest stock level at 8806 pieces, while 174463-7 (yellow) has the lowest availability at 726 pieces.

All parts carry REACH Unaffected or Vendor Undefined status, with no regulatory restrictions on use. All parts are classified under ECCN EAR99 and HTSUS 8536.69.8000.

Frequently Asked Questions (FAQ)

Q: Can 776128-6 be directly replaced with any of the listed substitute parts?

A: Yes. All substitute parts maintain identical connector type, contact type, position count, pitch, mounting configuration, termination method, and fastening mechanism. Substitution is valid when housing color is not a design-critical parameter.

Q: What is the primary difference between 776128-6 and its substitutes?

A: Housing color is the only differentiating factor. The gray housing of 776128-6 can be replaced with white (174463-1, 368538-1), black (174463-2), yellow (174463-7), or natural (282365-1) options without affecting electrical or mechanical performance.

Q: Are there operating temperature differences between the main part and substitutes?

A: Part 776128-6 does not specify an operating temperature range in the provided data. Substitute parts 174463-1, 174463-2, 174463-7, and 282365-1 specify -30°C to 105°C operating range. Part 368538-1 does not specify an operating temperature range.

Q: Do all parts require separate contact procurement?

A: Yes. All parts in this comparison carry the note "Contacts Not Included." Crimp contacts must be sourced separately and are compatible with all listed housing options.

Q: Which substitute offers the best inventory availability?

A: Part 174463-2 (black) has the highest inventory level at 8806 pieces, followed by 368538-1 (white) at 7782 pieces and 282365-1 (natural) at 6300 pieces.

Q: Are there REACH or export compliance differences?

A: Part 282365-1 carries "Vendor Undefined" REACH status, while all other parts are REACH Unaffected. All parts are classified as EAR99 with no export restrictions.
