Molex 0050578907 Equivalent & Substitute Parts

Part Overview

The Molex 0050578907 is a 7-position rectangular connector housing designed for 0.100" (2.54mm) pitch applications. This receptacle housing accommodates female socket contacts with crimp termination and latch lock fastening. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing production and maintenance applications. Substitute parts maintain identical electrical and mechanical specifications while offering improved availability through active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0050578907 are qualified based on strict equivalence across the following critical parameters:

• Connector type: Receptacle housing
• Contact type: Female socket
• Number of positions: 7
• Pitch specification: 0.100" (2.54mm)
• Number of rows: 1
• Mounting configuration: Free Hanging (In-Line)
• Contact termination method: Crimp
• Fastening mechanism: Latch Lock
• Housing color: Black
• Series designation: SL 70066
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The substitute parts 0050579407 and 0050579707 maintain identical specifications across all these parameters. The primary distinction is product status: both substitutes are active components with improved inventory availability compared to the obsolete original part number.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 0050579407 and 0050579707 are direct functional equivalents to the obsolete Molex 0050578907. Selection between substitutes should be based on inventory availability and packaging requirements:

• Part 0050579407 offers the highest inventory level (43,803 pcs) with bulk packaging
• Part 0050579707 provides an alternative with moderate inventory (4,207 pcs) and bulk packaging

Both substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part. The operating temperature range (-40°C ~ 105°C) and insulation material specifications (Polyester, Glass Filled) are documented for the active substitutes and represent standard performance characteristics for this connector series.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts mechanically compatible with the original 0050578907?

A: Yes. Both substitute parts maintain identical mechanical specifications including connector type, position count, pitch, mounting configuration, and fastening mechanism. Direct substitution is supported without design modification.

Q: What is the primary reason for substituting the 0050578907?

A: The original part number is classified as obsolete. The substitute parts 0050579407 and 0050579707 are active products with significantly higher inventory availability, ensuring supply chain continuity.

Q: Do the substitute parts require different contact specifications?

A: No. Both substitutes maintain the same contact type (female socket) and termination method (crimp) as the original part. Existing contact inventory and assembly processes remain compatible.

Q: How do packaging differences affect part selection?

A: Both substitute parts are supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility. Selection should be based on inventory availability and procurement lead times.

Q: Are there any compliance differences between the original and substitute parts?

A: No. All three part numbers maintain identical RoHS3 compliance and REACH unaffected status. Regulatory requirements are fully satisfied by either substitute.

Q: Can the substitute parts be used in existing assemblies designed for the 0050578907?

A: Yes. The substitute parts are direct functional equivalents with identical specifications across all critical parameters. No design changes or re-qualification are required.
