3M 159144-2002 Equivalent & Substitute Parts

Part Overview

The 3M 159144-2002 is a rectangular connector header designed for surface mount applications with 44 positions at 2.00mm pitch. This component features a shrouded 4-wall design with male pin contacts, solder termination, and detent lock fastening. The part is classified as obsolete, making equivalent substitute components necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility across critical electrical and mechanical parameters including pitch, position count, contact configuration, and voltage/current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3M 159144-2002 are qualified based on the following critical parameters that determine functional compatibility:

Core Compatibility Parameters:

• Connector type (Header) and contact type (Male Pin)
• Position count (44) and row configuration (2 rows)
• Mating pitch (0.079" / 2.00mm) and row spacing (0.079" / 2.00mm)
• Surface mount mounting type
• Shrouded 4-wall design
• Solder termination method
• Voltage rating (minimum 150V)
• Current rating (minimum 1.25A)
• Operating temperature range coverage
• UL94 V-0 flammability rating

The Amphenol ICC (FCI) Minitek® 2.00mm series parts 98424-F52-44LF and 98424-G52-44LF meet these core requirements. Both parts feature identical position counts, pitch specifications, mounting configurations, and shrouding. The substitute parts exceed the original voltage (200V vs. 150V) and current (2A vs. 1.25A) ratings, providing enhanced electrical performance margins. Both substitute parts maintain UL94 V-0 compliance and unlimited moisture sensitivity level (MSL 1).

Parameter Comparison

Engineering Selection Recommendations

Both Amphenol ICC (FCI) substitute parts are active production components with established supply chains, addressing the obsolescence status of the 3M 159144-2002. The 98424-F52-44LF and 98424-G52-44LF maintain full electrical and mechanical compatibility with the original part across all critical parameters.

98424-F52-44LF features standard gold mating contact finish with flash thickness specification, suitable for general-purpose applications requiring the specified electrical performance.

98424-G52-44LF incorporates GXT™ gold contact finish with 30.0µin (0.76µm) thickness specification, matching the original part's contact finish thickness and providing enhanced contact durability characteristics.

Both substitute parts exceed the original voltage and current ratings, providing additional performance margin. RoHS compliance is maintained across all parts. The substitute components are available in bulk packaging with higher inventory levels than the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can 98424-F52-44LF and 98424-G52-44LF be used interchangeably with 3M 159144-2002?

A: Both Amphenol ICC (FCI) parts are functionally equivalent to the 3M 159144-2002 across all critical electrical and mechanical parameters. The 44-position, 2.00mm pitch, shrouded 4-wall header configuration, surface mount termination, and contact specifications are identical. The substitute parts exceed the original voltage and current ratings.

Q: What is the difference between 98424-F52-44LF and 98424-G52-44LF?

A: The primary difference is the mating contact finish specification. The 98424-F52-44LF uses flash gold plating, while the 98424-G52-44LF uses GXT™ gold plating with 30.0µin (0.76µm) thickness, matching the original part's contact finish thickness. Both parts maintain identical electrical and mechanical compatibility.

Q: Are there operating temperature limitations with the substitute parts?

A: The substitute parts do not specify an operating temperature range in the provided data. The original 3M 159144-2002 operates from -55°C to 105°C. Confirm operating temperature requirements with the component manufacturer if this parameter is critical for your application.

Q: Do the substitute parts maintain RoHS compliance?

A: Yes. Both 98424-F52-44LF and 98424-G52-44LF are RoHS compliant. The original 3M 159144-2002 is ROHS3 compliant. All parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What are the packaging differences?

A: The original 3M 159144-2002 packaging type is not specified in the provided data. Both substitute parts are supplied in bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Are there any contact length differences between the original and substitute parts?

A: Yes. The 3M 159144-2002 has a mating contact length of 0.142" (3.61mm), while both substitute parts have a mating contact length of 0.157" (4.00mm). The insulation height also differs: 0.210" (5.33mm) for the original versus 0.244" (6.20mm) for the substitutes. These dimensional differences may affect board layout and mating connector compatibility. Verify mechanical fit in your specific application.
