Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 5019390331 are identified through strict parametric matching of the following critical specifications:

Electrical Compatibility Parameters:

• Connector series: Pico-Clasp 501939
• Connector type: Receptacle
• Contact type: Female Socket
• Number of positions: 3
• Pitch: 0.039" (1.00mm)
• Contact termination: Crimp

Mechanical Compatibility Parameters:

• Number of rows: 1
• Mounting type: Free Hanging (In-Line)
• Fastening type: Latch Holder
• Insulation material: Polyamide (PA), Nylon

Environmental & Compliance Parameters:

• Operating temperature range: -40°C to 105°C
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The substitute part 5019390300 matches all critical electrical and mechanical parameters. Variations in packaging type (Bag versus Bulk) and housing color (Black versus White) do not affect functional interchangeability within the Pico-Clasp 501939 connector system.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 5019390331 and 5019390300 are active production parts within the Pico-Clasp 501939 connector series. Selection between these parts is determined by application-specific requirements rather than functional compatibility.

Primary Selection Criteria:

The 5019390331 is supplied in bag packaging with black housing color. The 5019390300 is supplied in bulk packaging with white housing color. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and assembly.

Inventory Availability:

The 5019390331 has 72,879 units in stock. The 5019390300 has 81,346 units in stock. Both parts maintain active production status.

Compliance Status:

Both parts meet identical environmental and regulatory specifications, including operating temperature range of -40°C to 105°C and compliance with ROHS3 and REACH standards.

Frequently Asked Questions (FAQ)

Q: Can the 5019390300 be used as a direct replacement for the 5019390331?

A: Yes. Both parts are functionally equivalent within the Pico-Clasp 501939 connector system. They share identical electrical specifications (3-position, 1.00mm pitch, female socket receptacle), mechanical configuration (free-hanging, in-line mounting with latch holder fastening), and environmental ratings (-40°C to 105°C operating temperature).

Q: What is the difference between these two parts?

A: The primary differences are housing color (black versus white) and packaging format (bag versus bulk). These differences do not affect electrical or mechanical compatibility. The 5019390300 includes a note that contacts are not included, whereas the 5019390331 packaging designation indicates a complete housing unit.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical RoHS3 compliance and REACH unaffected status. Both are suitable for applications requiring current regulatory compliance.

Q: Which part should be selected for new designs?

A: Selection should be based on specific application requirements including housing color preference and packaging quantity needs. Both parts are active production items with adequate inventory levels.

Q: Can these housings be used with contacts from other connector series?

A: No. These housings are designed specifically for the Pico-Clasp 501939 connector series and are compatible only with contacts and components within this series.

Q: What is the significance of the 1.00mm pitch specification?

A: The 1.00mm pitch (0.039 inches) defines the center-to-center spacing between contact positions. This specification must match the mating connector and contact set. Both substitute parts maintain this identical pitch specification.
