M20-9952445 Equivalent & Substitute Parts

Part Overview

The M20-9952445 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole, right-angle mounting applications. This 48-position connector with 2.54mm pitch serves board-to-board and cable interconnection requirements. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M20-9952445 is determined by strict equivalence across the following critical parameters:

• 48-position connector configuration with 2-row layout
• 0.100" (2.54mm) mating pitch and row spacing
• Male pin contact type for board-to-board or cable applications
• Through-hole, right-angle mounting with solder termination
• 3A current rating per contact
• Operating temperature range of -40°C to 105°C
• UL94 V-0 flammability rating
• ROHS3 compliance

The substitute part PREC024DBAN-M71RC from Sullins Connector Solutions meets all critical electrical and mechanical parameters. Variations in contact finish material (gold versus tin), insulation material composition (Nylon 6T versus PBT), and connector style designation (cuttable versus breakaway) do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

The PREC024DBAN-M71RC from Sullins Connector Solutions is the designated substitute for the obsolete M20-9952445. Both parts maintain identical electrical performance specifications, including 3A current rating and -40°C to 105°C operating temperature range. Both achieve UL94 V-0 flammability classification and ROHS3 compliance.

The Sullins part carries active product status, ensuring ongoing availability and supply chain continuity. Physical dimensions remain within acceptable tolerance ranges for PCB mounting and mating interface compatibility. The transition from gold to tin contact finish and from Nylon 6T to PBT insulation material does not compromise functional equivalence within the specified parameter set.

Frequently Asked Questions (FAQ)

Q: Can PREC024DBAN-M71RC directly replace M20-9952445 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), row configuration (2 rows, 48 positions), contact type (male pin), mounting method (through-hole, right-angle), and current rating (3A). Physical dimension variations are within acceptable tolerance for PCB layout compatibility.

Q: What is the difference between "cuttable" and "breakaway" connector styles?

A: Both designations refer to connector headers that can be separated into individual or smaller groups of pins. The functional performance and mating characteristics remain equivalent for board-to-board applications.

Q: Does the change from gold to tin contact finish affect performance?

A: Both finishes provide adequate electrical conductivity and corrosion resistance within the specified operating temperature range and current rating. The selection between gold and tin is determined by application-specific requirements and cost considerations, not functional interchangeability.

Q: Are there any packaging differences between these parts?

A: The M20-9952445 packaging specification is not provided. The PREC024DBAN-M71RC is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: What is the significance of the different insulation materials?

A: Nylon 6T and PBT are both thermoplastic materials meeting UL94 V-0 flammability requirements. Both materials maintain structural integrity across the -40°C to 105°C operating temperature range. Material selection does not affect electrical performance or mating compatibility.
