M50-4700745 Equivalent & Substitute Parts

Part Overview

The M50-4700745 is a rectangular connector header manufactured by Harwin Inc., part of the Archer M50 series. This is a through-hole vertical mount connector with 14 positions arranged in 2 rows at 0.050" (1.27mm) pitch. The connector features shrouded 4-wall design with gold-plated copper alloy contacts and liquid crystal polymer insulation rated UL94 V-0.

The M50-4700745 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M50-4700745 is determined by the following critical parameters:

• Manufacturer and Series: Harwin Inc. Archer M50 series maintains consistent mechanical and electrical interfaces
• Connector Type and Contact Type: Header with male pin contacts
• Pitch and Row Spacing: 0.050" (1.27mm) mating pitch and row spacing ensure PCB footprint compatibility
• Mounting Type and Termination: Through-hole solder termination
• Shrouding Configuration: Shrouded 4-wall design
• Contact Material and Finish: Copper alloy with gold plating
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature Range: -40°C ~ 105°C
• Current Rating: 1A per contact
• Compliance Standards: ROHS3 compliant, UL94 V-0 rated

The M50-4700845 qualifies as a substitute based on matching all critical parameters. The primary difference is the number of positions: 16 positions versus 14 positions in the original part. This difference does not affect substitution eligibility when the application requires or can accommodate the increased position count.

Parameter Comparison

Engineering Selection Recommendations

The M50-4700845 is the qualified substitute for the obsolete M50-4700745. Both parts maintain identical electrical and mechanical specifications across all critical parameters including pitch, row spacing, contact material, insulation properties, and operating temperature range.

The M50-4700845 offers the advantage of active product status, ensuring continued availability and supply chain reliability. Both parts carry equivalent compliance certifications: ROHS3 compliance and UL94 V-0 flammability rating.

The position count difference (16 versus 14) represents the only specification variance. Design integration requires confirmation that the increased position count is compatible with the target PCB layout and application requirements.

Frequently Asked Questions (FAQ)

Q: Can M50-4700845 directly replace M50-4700745 in existing designs?

A: The M50-4700845 shares identical pitch (0.050"), row spacing (0.050"), mounting type (through-hole), shrouding configuration (4-wall), and contact specifications with the M50-4700745. Direct replacement is possible when the application can accommodate the 16-position configuration. PCB footprint verification is required.
