Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0870492816 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 28 positions in 2 rows
• Pitch Specifications: 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Orientation: Through-hole, right-angle mounting
• Contact Materials & Finishes: Phosphor bronze with gold mating surface and tin-based post finish
• Insulation Specifications: PCT glass-filled material with UL94 V-0 rating
• Environmental Compliance: MSL 1 rating and REACH unaffected status

The Molex 0877602816 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status: the 0877602816 is Active, whereas the 0870492816 is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0877602816 is the direct substitute for the obsolete 0870492816. Both connectors maintain identical mechanical and electrical specifications across all critical parameters including pitch, position count, contact materials, and insulation properties.

The 0877602816 offers the advantage of Active product status, ensuring ongoing availability and manufacturing support. Additionally, the 0877602816 achieves ROHS3 compliance, whereas the 0870492816 is RoHS non-compliant. This distinction is significant for applications subject to regulatory requirements or customer specifications mandating RoHS compliance.

The post finish differs slightly: the 0870492816 uses Tin-Lead while the 0877602816 uses Tin. The contact finish thickness on the post is marginally higher on the 0877602816 (78.7µin versus 74.8µin), representing a negligible difference within standard manufacturing tolerances.

The 0877602816 supports both board-to-board and cable applications, providing greater application flexibility compared to the board-to-board-only specification of the 0870492816.

Frequently Asked Questions (FAQ)

Q: Are the 0870492816 and 0877602816 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (2.00mm), position count (28 in 2 rows), mounting type (through-hole right-angle), and contact dimensions. They are mechanically interchangeable in board-to-board applications.

Q: What is the significance of the RoHS compliance difference?

A: The 0877602816 is ROHS3 compliant while the 0870492816 is RoHS non-compliant. For applications or markets requiring RoHS compliance, the 0877602816 is the appropriate selection. The compliance difference reflects manufacturing process updates rather than functional capability changes.

Q: Does the post finish difference (Tin-Lead versus Tin) affect compatibility?

A: The post finish difference does not affect electrical or mechanical compatibility. Both finishes provide adequate solderability and contact reliability. The choice between them is typically driven by manufacturing process requirements and regulatory considerations (lead-free versus lead-containing finishes).

Q: Can the 0877602816 be used in cable applications where the 0870492816 cannot?

A: The 0877602816 specification explicitly supports both board-to-board and cable applications, while the 0870492816 is specified for board-to-board only. If cable connectivity is required, the 0877602816 is the appropriate selection.

Q: What packaging is available for the substitute part?

A: The 0877602816 is supplied in Tray packaging. Packaging specifications for the 0870492816 were not provided in the original documentation.

Q: Are there any electrical performance differences between these connectors?

A: No electrical performance differences exist. Both connectors use identical contact materials (phosphor bronze), mating contact finish (gold), and insulation materials (PCT glass-filled). Electrical characteristics including current and voltage ratings are equivalent.
