TE Connectivity AMP Connectors 2029027-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2029027-2 is a 2-position rectangular connector plug housing in the VAL-U-LOK series. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and component procurement. The connector features a black polyamide housing with male pin contact termination and crimp-based fastening through a locking ramp mechanism. As an obsolete product, sourcing alternatives from active product lines or equivalent series becomes necessary for system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2029027-2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug
• Contact Type: Male Pin
• Number of Positions: 2
• Number of Rows: 2
• Row Spacing: 0.165" (4.20mm)
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Locking Ramp
• Insulation Material: Polyamide (PA) or Nylon-based composition
• Operating Temperature Range: -40°C ~ 105°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Acceptable Variation:

• Color: Black housing is the primary specification; alternative colors within the same series may serve as functional equivalents where mechanical and electrical parameters remain identical
• Manufacturer: Equivalent parts from different manufacturers (such as Molex) are acceptable when all electrical and mechanical parameters align

The substitute parts identified below meet all mandatory matching parameters and are therefore electrically and mechanically interchangeable with the original 2029027-2 component.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 2029090-2

The TE Connectivity 2029090-2 is a parametric equivalent within the same VAL-U-LOK series. This part matches all critical electrical and mechanical parameters with the original 2029027-2, including connector type, contact configuration, row spacing, termination method, and fastening mechanism. The primary distinction is housing color (red versus black). Both parts share identical operating temperature ranges (-40°C ~ 105°C), RoHS3 compliance status, and MSL rating of 1 (Unlimited). The 2029090-2 remains classified as obsolete, consistent with the original part status.

Secondary Substitute: Molex 0469990275

The Molex 0469990275 from the Mini-Fit Jr 5559 series provides cross-manufacturer equivalency. This part maintains all mandatory matching parameters: 2-position plug configuration, male pin contacts, 2-row arrangement with 0.165" (4.20mm) row spacing, free-hanging in-line mounting, crimp termination, and locking ramp fastening. The insulation material composition differs slightly (PA66 Nylon 6/6 versus PA Nylon), but both are polyamide-based materials meeting the same functional requirements. Critically, the Molex 0469990275 carries active product status, making it the preferred long-term sourcing option for new applications or system replacements. This part is ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status. The Molex part is available in bulk packaging with significantly higher inventory levels (20,472 pieces in stock).

Selection Criteria:

For immediate replacement of existing 2029027-2 components in operational systems, the TE Connectivity 2029090-2 provides direct series compatibility. For new designs or long-term procurement strategies, the Molex 0469990275 is recommended due to its active product status and superior availability.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2029090-2 directly replace the 2029027-2 in existing assemblies?

A: Yes. The 2029090-2 is a parametric equivalent with identical electrical and mechanical specifications. The housing color difference (red versus black) does not affect functional compatibility. Both parts feature the same 2-position male pin configuration, 0.165" row spacing, crimp termination, and locking ramp fastening mechanism.

Q: What is the primary advantage of selecting the Molex 0469990275 over the TE Connectivity alternatives?

A: The Molex 0469990275 carries active product status, ensuring long-term availability and supply chain continuity. Both TE Connectivity options (2029027-2 and 2029090-2) are classified as obsolete. The Molex part is available in significantly higher quantities (20,472 pieces in stock) and is supplied in bulk packaging, supporting high-volume procurement requirements.

Q: Are there material compatibility concerns when substituting the Molex 0469990275 for the original TE Connectivity part?

A: No material compatibility issues exist. The Molex part uses PA66 Nylon 6/6 insulation material, while the original uses PA Nylon. Both are polyamide-based materials with equivalent performance characteristics for this connector application. Both materials support the identical operating temperature range of -40°C ~ 105°C.

Q: Do all substitute parts meet the same regulatory compliance standards?

A: Yes. All identified substitute parts (2029090-2 and 0469990275) are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original 2029027-2 specifications. The Molex part carries additional REACH Unaffected status.

Q: What is the significance of the "Contacts Not Included" notation?

A: This notation indicates that the connector housing is supplied without pre-installed contacts. Contacts must be sourced and crimped separately according to the application requirements. This specification applies uniformly across all three parts (2029027-2, 2029090-2, and 0469990275).

Q: Can the 2029090-2 and 0469990275 be used interchangeably in the same circuit board assembly?

A: Yes. Both parts meet all mandatory matching parameters for electrical and mechanical compatibility. Selection between these two options should be based on supply chain considerations, inventory availability, and long-term product lifecycle requirements rather than functional performance differences.
