Molex 0877580491 Equivalent & Substitute Parts

Part Overview

The Molex 0877580491 is an active rectangular connector header designed for through-hole mounting in board-to-board or cable applications. This 4-position, 2-row connector operates at 0.079" (2.00mm) pitch and features a breakaway design with unshrouded construction. The part is manufactured in the Milli-Grid 87758 series and maintains UL94 V-0 material flammability compliance. Equivalent parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring identical electrical and mechanical interface specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0877580491 is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 4
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Unshrouded
• Contact Shape: Square
• Insulation Height: 0.059" (1.50mm)

The Amphenol ICC (FCI) part number 57102-G06-02LF meets all critical electrical and mechanical interface requirements. Both connectors maintain identical mating pitch, position count, row configuration, and contact geometry. Both employ through-hole solder termination with push-pull fastening and unshrouded design. Material flammability compliance (UL94 V-0) is maintained across both parts.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0877580491 and Amphenol ICC 57102-G06-02LF maintain active product status with full regulatory compliance. The Molex part carries ROHS3 compliance with REACH Unaffected status. The Amphenol ICC substitute carries RoHS compliance with REACH Affected status. Both parts satisfy UL94 V-0 material flammability requirements and MSL 1 moisture sensitivity classification.

Selection between these parts should be based on supply availability, packaging format (Molex supplied in Tray; Amphenol ICC supplied in Bulk), and regulatory requirements specific to the end application. The Amphenol ICC part provides documented current rating (2A AC/DC) and voltage rating (200V AC/DC), whereas these parameters are not specified for the Molex part. Both connectors are electrically and mechanically interchangeable for board-to-board and cable interface applications requiring 2.00mm pitch, 4-position, 2-row through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0877580491 and Amphenol ICC 57102-G06-02LF mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.079" / 2.00mm), position count (4), row configuration (2 rows), row spacing (0.079" / 2.00mm), contact geometry (square male pins), insulation height (0.059" / 1.50mm), and mounting method (through-hole solder). Physical interface compatibility is confirmed.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching mating pitch, number of positions, number of rows, row spacing, contact type, mounting type, termination method, fastening type, shrouding configuration, and contact shape. All these parameters are identical between the Molex and Amphenol ICC parts.

Q: How do the packaging formats differ?

A: The Molex 0877580491 is supplied in Tray packaging, while the Amphenol ICC 57102-G06-02LF is supplied in Bulk packaging. Packaging format selection depends on procurement volume and inventory management requirements.

Q: Are there differences in contact finish specifications?

A: The Molex part specifies gold mating contact finish at 15.0µin (0.38µm) thickness. The Amphenol ICC part specifies gold with GXT™ enhancement at 30.0µin (0.76µm) thickness. Both employ tin post finish. The enhanced gold thickness on the Amphenol ICC part provides additional contact durability.

Q: What regulatory compliance differences exist between these parts?

A: The Molex part is ROHS3 Compliant with REACH Unaffected status. The Amphenol ICC part is RoHS Compliant with REACH Affected status. Both maintain UL94 V-0 material flammability compliance and MSL 1 moisture sensitivity classification.

Q: Are electrical ratings specified for both parts?

A: The Amphenol ICC 57102-G06-02LF provides documented electrical ratings of 2A (AC/DC) current and 200V (AC/DC) voltage. The Molex 0877580491 does not specify these parameters in available documentation.
