TE Connectivity 2029088-2 Rectangular Connector Plug Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2029088-2 is a 2-position rectangular connector plug housing from the VAL-U-LOK series. This component is a black polyamide housing designed for panel mount, snap-in applications with crimp contact termination and locking ramp fastening. The part is currently active in production status with 860 pieces available in inventory.

Substitute parts are identified when equivalent rectangular connector housings share identical or compatible electrical and mechanical parameters, including connector type, number of positions, row configuration, row spacing, mounting method, contact termination, fastening type, insulation material, and operating temperature range. Substitution becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or design flexibility permits alternative series selection within compatible parameter specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 2029088-2 are identified based on strict parameter equivalence across the following critical specifications:

Electrical Parameters:

• Connector type: Plug
• Contact type: Male Pin
• Number of positions: 2
• Number of rows: 2
• Row spacing: 0.165" (4.20mm)

Mechanical Parameters:

• Mounting type: Panel Mount, Snap-In
• Contact termination: Crimp
• Fastening type: Locking Ramp
• Insulation material: Polyamide (PA) or Polyamide (PA66), Nylon

Environmental Parameters:

• Operating temperature range: -40°C to 105°C (or extended range compatible)
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance status: RoHS Compliant or ROHS3 Compliant

Parts meeting all these criteria are classified as parametric equivalents. Variations in color (black versus natural) and series designation do not affect functional substitutability when all electrical, mechanical, and environmental parameters remain identical or compatible.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1586018-2 (VAL-U-LOK Series)

The 1586018-2 is a direct parametric equivalent to the 2029088-2, sharing identical electrical, mechanical, and environmental specifications. Both parts are from the VAL-U-LOK series, maintain active production status, and carry RoHS compliance certification. The primary distinction is housing color (natural versus black). This part is suitable for direct substitution when color specification permits. Current inventory of 2300 pieces provides availability advantage over the main part.

TE Connectivity 794550-2 (AMP-DUAC Series)

The 794550-2 meets all critical substitution parameters with one exception: extended operating temperature range of -55°C to 105°C compared to the main part's -40°C to 105°C. This part is discontinued at DiGi Electronics, limiting long-term procurement viability. Selection of this part is appropriate only when the extended low-temperature capability is required and inventory availability is confirmed. Current inventory of 680 pieces is available.

Molex 0039012021 (Mini-Fit Jr 5559 Series)

The 0039012021 is a cross-manufacturer parametric equivalent from Molex, meeting all electrical, mechanical, and environmental specifications. The insulation material specification differs slightly (PA66 Nylon 6/6 versus PA Nylon), but both materials are polyamide-based and functionally compatible within the defined operating parameters. This part carries ROHS3 compliance and REACH Unaffected status. Significantly higher inventory availability of 23116 pieces supports procurement flexibility. Selection of this part is appropriate for applications where cross-manufacturer sourcing is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 1586018-2 be used as a direct replacement for the 2029088-2?

A: Yes. The 1586018-2 is a parametric equivalent meeting all electrical, mechanical, and environmental specifications. The only difference is housing color (natural versus black). Substitution is valid when color specification does not impose design constraints.

Q: What is the significance of the operating temperature range difference in the 794550-2?

A: The 794550-2 extends the low-temperature operating limit to -55°C compared to the main part's -40°C. This extended range provides additional thermal margin for applications requiring operation in extreme cold environments. The upper temperature limit remains identical at 105°C.

Q: Is the Molex 0039012021 compatible with TE Connectivity connector systems?

A: The 0039012021 is a parametric equivalent based on electrical, mechanical, and environmental specifications. However, cross-manufacturer connector compatibility depends on mating connector design and contact specifications. Verify mating connector compatibility before final selection.

Q: What does the insulation material difference between PA and PA66 mean for substitution?

A: Both polyamide (PA) and polyamide 6/6 (PA66) are polyamide-based thermoplastic materials with similar thermal and mechanical properties within the specified operating range. The difference does not affect functional substitutability for the defined electrical and mechanical parameters.

Q: Why is the 794550-2 listed as discontinued?

A: The 794550-2 is discontinued at DiGi Electronics, indicating reduced availability through primary distribution channels. While inventory is currently available, long-term procurement cannot be guaranteed. Selection of this part should be limited to applications where extended temperature range is essential and alternative sources are confirmed.

Q: How does inventory availability affect part selection?

A: Inventory levels influence procurement timeline and cost. The 0039012021 offers the highest availability at 23116 pieces, followed by 1586018-2 at 2300 pieces. Higher inventory typically supports faster delivery and reduced lead time risk.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part and all substitute parts carry RoHS compliance certification (RoHS Compliant or ROHS3 Compliant), meeting environmental regulatory requirements for restricted substance elimination.

Q: What is Moisture Sensitivity Level (MSL) 1, and why is it important?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. All listed parts carry MSL 1 rating, eliminating the need for specialized storage or baking procedures prior to assembly.
