Molex 5046940402 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 5046940402 is a 4-position rectangular connector plug housing with 3.30mm pitch, designed for free-hanging in-line applications. This component features crimp contact termination and latch lock fastening, constructed from polybutylene terephthalate (PBT) insulation material. The part is Active in product status and ROHS3 compliant, suitable for operating environments ranging from -40°C to 105°C. Substitute parts are identified to provide alternative color options while maintaining identical electrical and mechanical specifications, enabling flexible design implementation and supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 5046940402 are identified based on strict parametric equivalence within the CP-3.3 504694 series. All substitute parts maintain identical specifications across the following critical parameters: connector type (Plug), contact type (Male Pin), number of positions (4), pitch (3.30mm), number of rows (1), mounting type (Free Hanging In-Line), contact termination (Crimp), fastening type (Latch Lock), insulation material (PBT), operating temperature range (-40°C to 105°C), product status (Active), RoHS compliance (ROHS3), and MSL rating (1). The only variable parameter among equivalent parts is the housing color. This color differentiation allows for circuit identification, wiring organization, and visual assembly verification without affecting electrical or mechanical performance. All substitute parts share the same base product number (504694) and are manufactured by Molex under identical design specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—5046940402 (Red), 5046940401 (Black), and 5046940403 (Yellow)—are Active products manufactured by Molex and carry ROHS3 compliance certification. Selection between these equivalent parts should be based on application-specific requirements for housing color identification and circuit organization. The MSL rating of 1 (Unlimited) indicates these components have no moisture sensitivity restrictions and do not require special storage or handling protocols. All parts maintain identical electrical and mechanical performance characteristics, making them fully interchangeable from a functional standpoint. Inventory availability should be considered as a secondary factor: 5046940401 (Black) has 14,944 units in stock, 5046940403 (Yellow) has 14,773 units in stock, and 5046940402 (Red) has 913 units in stock.

Frequently Asked Questions (FAQ)

Q: Can I substitute 5046940401 (Black) for 5046940402 (Red) in my design? A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The only difference is housing color. Substitution is valid if color coding is not a functional requirement in your application.

Q: Are these parts compatible with the same contact pins? A: Yes. All three housing variants accept identical crimp contacts designed for the CP-3.3 504694 series. Contact specifications remain unchanged across color variants.

Q: What is the pitch specification, and does it affect substitution? A: The pitch is 0.130" (3.30mm) for all three parts. This specification is identical across all substitutes and determines contact spacing and mating compatibility.

Q: Do these parts require special storage or handling? A: No. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity. Standard component storage conditions are sufficient.

Q: What is the operating temperature range for these connectors? A: All three parts operate from -40°C to 105°C. This range is identical across all substitutes.

Q: Are all three parts ROHS3 compliant? A: Yes. All parts carry ROHS3 compliance certification, meeting regulatory requirements for restricted substance elimination.

Q: What is the difference between these parts and other Molex rectangular connectors? A: These parts are specific to the CP-3.3 504694 series with 4-position, 3.30mm pitch configuration. Other series may have different pitch, position count, or mounting specifications.

Q: Can I use these housings without contacts? A: No. The product note specifies that contacts are not included. Contacts must be sourced separately and are designed for crimp termination into these housings.
