Molex 0430252408 Equivalent & Substitute Parts

Part Overview

The Molex 0430252408 is a 24-position rectangular connector receptacle housing from the Micro-Fit 3.0 series, designed for applications requiring compact, high-density interconnections with 3.00mm pitch spacing. This component is an active product with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or inventory constraints exist.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0430252408 are qualified based on strict equivalence of the following critical parameters:

Number of positions: 24
Pitch spacing: 0.118" (3.00mm)
Number of rows: 2
Row spacing: 0.118" (3.00mm)
Connector type: Receptacle
Contact type: Female Socket
Mounting type: Free Hanging (In-Line)
Contact termination: Crimp
Fastening type: Latch Lock
Color: Black
MSL rating: 1 (Unlimited)

Two substitute parts meet these criteria: Molex 0430252400 and TE Connectivity AMP Connectors 2-794617-4. Both maintain identical mechanical and electrical interface specifications, enabling direct substitution in applications where connector housing compatibility is the primary requirement.

Engineering Selection Recommendations

All three parts maintain active product status and comply with RoHS regulations, ensuring regulatory compliance for current applications. The Molex 0430252408 and Molex 0430252400 are both from the Micro-Fit 3.0 series and differ only in insulation material composition (Polyamide versus Polyester). The TE Connectivity 2-794617-4 represents a cross-manufacturer substitute from the Micro MATE-N-LOK series, offering equivalent mechanical and electrical interface specifications with documented operating temperature range of -40°C to 105°C. Selection between these substitutes depends on supply chain availability, existing inventory levels, and any design-specific material requirements not specified in the provided parameters.

Frequently Asked Questions (FAQ)

Q: Can Molex 0430252400 directly replace Molex 0430252408?

A: Yes. Both parts share identical mechanical and electrical interface parameters, including 24 positions, 3.00mm pitch, 2-row configuration, receptacle type, female socket contacts, crimp termination, and latch lock fastening. The difference in insulation material (Polyester versus Polyamide) does not affect connector housing compatibility.

Q: Is the TE Connectivity 2-794617-4 compatible with Molex connector systems?

A: The TE Connectivity 2-794617-4 maintains equivalent mechanical and electrical specifications for the connector housing interface. However, it belongs to the Micro MATE-N-LOK series rather than Micro-Fit 3.0. Compatibility depends on whether the mating connector and system design accommodate cross-series substitution. Verify mating connector compatibility before implementation.

Q: What is the significance of the MSL rating?

A: The MSL 1 (Unlimited) rating indicates these connector housings have unlimited shelf life and require no special moisture control during storage or handling, simplifying inventory management and reducing component preparation requirements.

Q: Are operating temperature specifications critical for substitution?

A: The Molex 0430252408 does not specify an operating temperature range in the provided data. The substitute parts (Molex 0430252400 and TE Connectivity 2-794617-4) both specify -40°C to 105°C operation. If the application requires operation outside this range, verify the original part's temperature capability through manufacturer documentation.

Q: What packaging format is used for these connector housings?

A: All three parts are supplied in bulk packaging, suitable for high-volume assembly operations. Contacts are not included and must be sourced separately according to application requirements.
