Substitute Part Grouping Explanation

Substitution of the Molex 0870893816 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 38 positions, 2 rows, 2.00mm pitch (mating and row spacing)
• Connector Type: Header, Breakaway with male pin contacts
• Mounting and Termination: Through-hole solder termination
• Contact Geometry: Square contact shape with 0.157" (4.00mm) mating length and 0.319" (8.10mm) overall contact length
• Contact Material and Finish: Phosphor bronze with gold mating finish (15.0µin thickness) and tin-based post finish
• Insulation: Polyamide (PA46), Nylon 4/6, Glass Filled material with UL94 V-0 flammability rating
• Application Compatibility: Automotive, General Purpose, and Telecommunications

The Molex 0877583816 satisfies all electrical and mechanical substitution criteria while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0877583816 is the direct functional equivalent to the obsolete Molex 0870893816. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including contact configuration, pitch, termination method, and material composition.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 0870893816 is classified as obsolete and carries RoHS non-compliant status, while the 0877583816 is an active product with ROHS3 compliance. The post contact finish differs slightly (Tin-Lead versus Tin), which does not affect electrical performance or mechanical compatibility.

For new designs or ongoing production requiring RoHS compliance, the 0877583816 is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, the 0877583816 remains functionally equivalent and offers the advantage of active product support and availability.

Frequently Asked Questions (FAQ)

Q: Are the 0870893816 and 0877583816 mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (2.00mm), row spacing (2.00mm), contact geometry, and mounting configuration. They are direct mechanical substitutes.

Q: What is the difference in post contact finish between Tin-Lead and Tin?

A: The 0870893816 uses Tin-Lead post finish while the 0877583816 uses Tin post finish. Both finishes provide equivalent solder joint reliability and electrical performance. The Tin finish in the 0877583816 reflects modern lead-free manufacturing practices.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a regulatory and material sourcing designation that does not affect the electrical or mechanical performance of the connector. The 0877583816 is ROHS3 compliant, making it suitable for applications with regulatory requirements.

Q: Can the 0877583816 be used as a direct replacement in existing assemblies designed for the 0870893816?

A: Yes. The 0877583816 is a direct functional and mechanical equivalent. No design modifications are required for substitution.

Q: What is the packaging difference between these parts?

A: The 0870893816 packaging is not specified in the available data. The 0877583816 is supplied in Tray packaging. Confirm packaging requirements with your procurement specifications.

Q: Are there any thermal or electrical rating differences?

A: Operating temperature, current rating, and voltage rating are not specified for either part in the available technical data. Consult the manufacturer's detailed datasheets for complete thermal and electrical specifications.
