Substitute Part Grouping Explanation

Substitution eligibility for the 1-2008570-4 is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (4), pitch (0.118" / 3.00mm), number of rows (1), mounting type (free hanging in-line), contact termination (crimp), and fastening type (latch lock). All substitute parts maintain identical electrical and mechanical specifications within these parameters.

Substitute parts are grouped into two categories:

TE Connectivity Micro MATE-N-LOK Series (Same Manufacturer): Parts 1445022-4, 2008570-4, 2029047-4, and 2029102-4 are direct equivalents within the TE Connectivity product line. These parts differ only in color specification (Natural or Black) and base product number designation, with no impact on functional compatibility.

Molex Micro-Fit 3.0 Series (Alternative Manufacturer): Parts 0436450400 and 0436450408 are parametric equivalents from Molex. These parts maintain identical electrical and mechanical specifications but originate from a different manufacturer and series designation. Both operate within the same temperature range and MSL rating.

Engineering Selection Recommendations

TE Connectivity Micro MATE-N-LOK Equivalents (1445022-4, 2008570-4, 2029047-4, 2029102-4): These parts maintain full compatibility within the TE Connectivity connector ecosystem. Selection among these options is determined by color requirement and RoHS compliance status. Part 2029047-4 offers the highest inventory availability (28,101 units) with ROHS3 compliance. Part 2029102-4 provides a Natural color alternative with RoHS compliance and substantial inventory (10,677 units). Part 1445022-4 offers Black color with RoHS compliance and moderate inventory (1,457 units).

Molex Micro-Fit 3.0 Equivalents (0436450400, 0436450408): These parts provide cross-manufacturer substitution with identical electrical and mechanical parameters. Both parts carry ROHS3 compliance and REACH Unaffected status. Part 0436450408 provides the highest inventory availability (61,789 units) with Polyamide (PA) Nylon insulation material. Part 0436450400 offers comparable availability (48,080 units) with Polyester insulation material. Cross-manufacturer substitution requires verification of mating connector compatibility at the system level.

Compliance Considerations: All substitute parts maintain MSL 1 (Unlimited) rating and operate within the specified temperature range of -40°C to 105°C. ROHS3 compliance is confirmed for parts 1-2008570-4, 2029047-4, 0436450400, and 0436450408. RoHS compliance (non-3) is confirmed for parts 1445022-4, 2008570-4, and 2029102-4.

Frequently Asked Questions (FAQ)

Q: Can I substitute a TE Connectivity Micro MATE-N-LOK part with a Molex Micro-Fit 3.0 part?

A: Substitution is possible when all electrical and mechanical parameters match: 4-position receptacle, 0.118" (3.00mm) pitch, crimp termination, and latch lock fastening. However, cross-manufacturer substitution requires system-level verification of mating connector compatibility, as the two series originate from different manufacturers and may have subtle design differences in housing geometry or contact interface.

Q: What is the difference between the Natural and Black color variants?

A: Color is a cosmetic specification that does not affect electrical or mechanical function. Natural color parts (1-2008570-4, 2029102-4) and Black color parts (1445022-4, 2008570-4, 2029047-4, 0436450400, 0436450408) are functionally equivalent. Selection is based on application requirements or design specifications.

Q: Are all substitute parts RoHS compliant?

A: ROHS3 compliance is confirmed for parts 1-2008570-4, 2029047-4, 0436450400, and 0436450408. Parts 1445022-4, 2008570-4, and 2029102-4 carry RoHS compliance (non-3 designation). Verify compliance requirements for your specific application before selection.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life without special moisture control measures. All substitute parts carry MSL 1 rating, eliminating moisture-related handling constraints during storage and assembly.

Q: Do these parts include contacts?

A: No. All listed parts are housings only. Contacts are not included and must be sourced separately. Ensure contact specifications match the housing pitch (0.118" / 3.00mm) and termination type (crimp).

Q: What is the operating temperature range for these connectors?

A: All substitute parts operate within -40°C to 105°C. This range applies to both TE Connectivity and Molex equivalents and is suitable for industrial and commercial applications within standard environmental conditions.

Q: Can I use part 2029047-4 as a direct replacement for 1-2008570-4?

A: Yes. Part 2029047-4 is a direct parametric equivalent with identical electrical and mechanical specifications. The only difference is color (Black versus Natural) and base product number designation. Functional compatibility is confirmed across all critical parameters.
