TE Connectivity 2008571-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2008571-4 is a 4-position rectangular connector receptacle housing from the Micro MATE-N-LOK series. This component is a black polyamide receptacle designed for free-hanging in-line mounting with crimp contact termination and latch lock fastening. The part is currently active in production with 654 pieces available in inventory.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits the use of functionally compatible components from different manufacturers or product series within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector receptacle housings is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Connector type (Receptacle)
Contact type (Female Socket)
Number of positions (4)
Pitch specification (0.118" / 3.00mm)
Number of rows (1)
Mounting type (Free Hanging In-Line)
Contact termination method (Crimp)
Fastening type (Latch Lock)
Operating temperature range (-40°C ~ 105°C)
Moisture sensitivity level (1 - Unlimited)

Parts meeting all primary criteria are classified as parametric equivalents. Secondary variations in insulation material composition (polyamide PA versus PA66, or polyester) and color (black versus natural) do not disqualify substitution when all primary parameters align. Manufacturer differences (TE Connectivity versus Molex) do not affect substitution eligibility when electrical and mechanical specifications are identical.

Engineering Selection Recommendations

TE Connectivity Micro MATE-N-LOK Series (Same Manufacturer):

The TE Connectivity substitute parts 2008570-4, 1445022-4, 2029047-4, and 2029102-4 maintain full parametric equivalence with the primary part 2008571-4 across all critical electrical and mechanical specifications. All parts are active products with RoHS compliance certifications. Part 2029047-4 offers the highest inventory availability (28,101 pieces) among TE Connectivity options and carries ROHS3 Compliant status matching the primary part. Part 2008570-4 provides the second-highest availability (11,298 pieces) with RoHS Compliant certification. Part 2029102-4 differs only in color specification (natural versus black) and remains fully substitutable for applications where color is not a design constraint.

Molex Micro-Fit 3.0 Series (Cross-Manufacturer):

Parts 0436450408 and 0436450400 from Molex are parametric equivalents meeting all primary substitution criteria. Part 0436450408 uses polyamide (PA) nylon insulation material identical to the primary part and carries ROHS3 Compliant certification. This part offers the highest overall inventory availability (61,789 pieces) among all listed substitutes. Part 0436450400 uses polyester insulation material and also carries ROHS3 Compliant certification with substantial inventory (48,080 pieces). Both Molex parts are active products suitable for direct substitution in applications where cross-manufacturer compatibility is acceptable.

Frequently Asked Questions (FAQ)

Q: Can 2008570-4 be used as a direct replacement for 2008571-4?

A: Yes. Part 2008570-4 is a parametric equivalent with identical electrical and mechanical specifications. Both are TE Connectivity Micro MATE-N-LOK receptacles with 4 positions, 0.118" pitch, crimp termination, and latch lock fastening. The primary difference is RoHS certification status (RoHS Compliant versus ROHS3 Compliant). Part 2008570-4 has significantly higher inventory availability (11,298 pieces).

Q: What is the difference between 1445022-4 and 2008571-4?

A: Both parts are TE Connectivity Micro MATE-N-LOK 4-position receptacles with identical pitch, mounting, and fastening specifications. The material difference is in the polyamide composition: 1445022-4 specifies PA66 (Nylon 6/6) while 2008571-4 specifies PA (Nylon). Both materials meet the same operating temperature range (-40°C ~ 105°C) and moisture sensitivity requirements. Both carry RoHS compliance certifications.

Q: Can Molex 0436450408 replace TE Connectivity 2008571-4?

A: Yes. Part 0436450408 is a parametric equivalent from a different manufacturer. It meets all primary substitution criteria: 4 positions, 0.118" pitch, female socket contacts, crimp termination, latch lock fastening, and identical operating temperature range. The connector series differs (Micro-Fit 3.0 versus Micro MATE-N-LOK), but electrical and mechanical compatibility is maintained. Both parts carry ROHS3 Compliant certification.

Q: Why does 2029102-4 have different color than 2008571-4?

A: Part 2029102-4 is specified in natural color while 2008571-4 is black. This is the only difference between the two parts. All electrical and mechanical parameters are identical. Selection between these parts depends on application requirements for connector color. Both are TE Connectivity Micro MATE-N-LOK receptacles with full parametric equivalence.

Q: What is the difference between polyamide (PA) and polyester insulation in these connectors?

A: Both materials are used in the listed substitute parts and meet the same operating temperature range (-40°C ~ 105°C) and moisture sensitivity level (1 - Unlimited). Polyamide (PA) nylon is used in parts 2008571-4, 2008570-4, 2029047-4, 2029102-4, and 0436450408. Polyester is used in part 0436450400. Selection between these materials depends on specific application environmental and chemical exposure requirements not specified in the parametric data.

Q: Are all listed parts currently in active production?

A: Yes. All substitute parts listed carry Active product status. Inventory availability varies: 2029047-4 (28,101 pieces), 0436450408 (61,789 pieces), 0436450400 (48,080 pieces), 2008570-4 (11,298 pieces), 2029102-4 (10,677 pieces), and 1445022-4 (1,457 pieces).
