Molex 0877585017 Equivalent & Substitute Parts

Part Overview

The Molex 0877585017 is a rectangular connector header designed for through-hole mounting in board-to-board applications. This vertical 50-position connector operates at 2.00mm pitch and features male pins with gold-plated mating contacts and tin-plated posts. The part is currently active in production with full inventory availability. Substitute parts are identified to address packaging preferences, compliance variations, and contact finish specifications while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0877585017 are qualified based on the following critical parameters that must remain constant across all alternatives:

• Connector type: Header with male pins
• Number of positions: 50
• Number of rows: 2
• Pitch - mating: 0.079" (2.00mm)
• Row spacing - mating: 0.079" (2.00mm)
• Mounting type: Through hole
• Termination: Solder
• Contact shape: Square
• Contact finish - mating: Gold
• Contact finish - post: Tin
• Insulation material: Thermoplastic or glass-filled polyamide
• Material flammability rating: UL94 V-0
• Fastening type: Push-Pull
• Style: Board to board

The four qualified substitutes are manufactured by Amphenol ICC (FCI) under the Minitek® 2.00mm series. Variations exist in packaging format (Box, Tube, Bulk), contact length specifications, contact finish thickness, and RoHS/REACH compliance status. These variations do not affect functional interchangeability in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain full electrical and mechanical compatibility with the Molex 0877585017 for standard board-to-board applications. Selection among substitutes is determined by packaging requirements and compliance specifications:

57102-F08-25LF (Box Packaging): Suitable for applications requiring standard box packaging. Offers RoHS compliance with REACH affected status. Current rating 2A (AC/DC), voltage rating 200V (AC/DC).

57102-F08-25ULF (Tube Packaging): Identical electrical specifications to 57102-F08-25LF with tube packaging format. Highest inventory availability (975 pcs). RoHS compliant with REACH affected status.

57102-G06-25LF (Bulk Packaging): Bulk packaging option with highest inventory (1558 pcs). Features GXT™ contact finish on mating surface with 30.0µin thickness. RoHS compliant with REACH affected status.

57102-S06-25LF (Box Packaging): Bulk packaging with GXT™ contact finish and reduced mating contact finish thickness (15.0µin). RoHS unaffected status aligns with Molex part ROHS3 compliance. Highest inventory availability (1843 pcs).

The Molex 0877585017 carries ROHS3 compliance and REACH unaffected status. The 57102-S06-25LF substitute most closely aligns with these compliance profiles while maintaining all critical electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically interchangeable with the Molex 0877585017?

A: Yes. All four substitute parts share identical mating pitch (2.00mm), position count (50), row configuration (2), contact type (male pin), and contact finish specifications (gold mating, tin post). Electrical performance is equivalent across all alternatives.

Q: What is the difference between the contact finish specifications listed for different substitutes?

A: The Molex part specifies 30.0µin (0.76µm) gold thickness on mating contacts. Amphenol substitutes 57102-F08-25LF and 57102-F08-25ULF use flash gold finish. The 57102-G06-25LF and 57102-S06-25LF variants include GXT™ enhanced gold plating with specified thickness values (30.0µin and 15.0µin respectively). These variations do not affect functional compatibility in standard applications.

Q: How do packaging formats affect part selection?

A: Packaging format (Box, Tube, Bulk) is a logistics consideration only and does not affect connector performance. Selection depends on procurement volume requirements and inventory management practices. Box packaging (57102-F08-25LF, 57102-S06-25LF) suits standard orders. Tube packaging (57102-F08-25ULF) accommodates automated assembly processes. Bulk packaging (57102-G06-25LF) supports high-volume production.

Q: What is the significance of RoHS and REACH compliance differences?

A: The Molex 0877585017 is ROHS3 compliant and REACH unaffected. Amphenol substitutes 57102-F08-25LF, 57102-F08-25ULF, and 57102-G06-25LF are RoHS compliant with REACH affected status. The 57102-S06-25LF matches the Molex compliance profile (ROHS3 equivalent and REACH unaffected). Compliance selection depends on end-application regulatory requirements and supply chain restrictions.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All parts maintain identical through-hole mounting footprints, solder termination specifications, and mechanical dimensions for the mating interface. PCB layout and assembly processes require no modification when substituting between qualified alternatives.

Q: What contact length variations exist among the substitutes?

A: The Molex part specifies 0.102" (2.60mm) post length with 0.319" (8.10mm) overall contact length. Amphenol 57102-F08 variants specify 0.118" (3.00mm) post length with 0.335" (8.51mm) overall length. Amphenol 57102-G06 and 57102-S06 variants specify 0.098" (2.50mm) post length with 0.315" (8.00mm) overall length. These variations remain within acceptable tolerances for standard board-to-board mating applications.
