Molex 5046940404 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 5046940404 is a 4-position rectangular connector plug housing with 3.30mm pitch, designed for free-hanging in-line applications. This component is part of the CP-3.3 504694 series and features crimp contact termination with latch lock fastening. The part is Active in product status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required but alternative color options or inventory availability necessitate component substitution.

Substitute Part Grouping Explanation

Substitute parts for the Molex 5046940404 are determined by strict equivalence across the following critical parameters:

• Connector Type: Plug
• Contact Type: Male Pin
• Number of Positions: 4
• Pitch: 0.130" (3.30mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Insulation Material: Polybutylene Terephthalate (PBT)
• Operating Temperature Range: -40°C to 105°C
• Series: CP-3.3 504694
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts (5046940401 and 5046940403) differ only in color designation (Black and Yellow respectively) while maintaining identical electrical and mechanical specifications. Color variation does not affect functional compatibility in applications where connector identification or circuit tracing is the primary purpose of color differentiation.

Parameter Comparison

Engineering Selection Recommendations

All three parts (5046940404, 5046940401, and 5046940403) maintain Active product status and ROHS3 compliance. Selection between these parts is based on application requirements for connector identification or circuit tracing through color coding. The electrical and mechanical performance characteristics are identical across all three variants. 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 5046940404 (Blue) has 924 units in stock. All parts are supplied in Bulk packaging and include the same operating temperature range and moisture sensitivity specifications.

Frequently Asked Questions (FAQ)

Q: Can 5046940401 (Black) be used in place of 5046940404 (Blue)?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical specifications for connector type, contact type, number of positions, pitch, mounting type, contact termination, fastening type, insulation material, and operating temperature range. The only difference is the housing color.

Q: Are there any compatibility issues when substituting between these three part numbers?

A: No compatibility issues exist. All three parts are from the same CP-3.3 504694 series and maintain identical functional specifications. Substitution is limited only by application requirements for color-based identification.

Q: Do these parts require contacts to be purchased separately?

A: Yes. All three parts are connector housings only. The product note specifies "Contacts Not Included." Contacts must be sourced separately and must be compatible with crimp termination and the 4-position, 3.30mm pitch configuration.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without special moisture control measures. These parts do not require desiccant packaging or controlled storage conditions.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three substitute parts (5046940404, 5046940401, and 5046940403) are ROHS3 compliant and suitable for applications with RoHS requirements.
