Molex 0873811074 Equivalent & Substitute Parts

Part Overview

The Molex 0873811074 is a 10-position receptacle connector in the Milli-Grid 87381 series, designed for surface mount board-to-board applications. This connector features 0.079" (2.00mm) pitch mating contacts with gold plating and operates across -55°C to 105°C. The part is currently active in production with 1075 units in stock.

Equivalent and substitute parts are identified when design requirements change, inventory constraints occur, or when alternative manufacturers offer compatible solutions meeting the same electrical and mechanical specifications. Substitutes must maintain compatibility across pitch, position count, mounting type, and contact characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0873811074 are qualified based on the following critical parameters that determine functional interchangeability:

Primary Matching Criteria:

• Connector type: Receptacle
• Contact type: Female Socket
• Number of positions: 10
• Pitch - mating: 0.079" (2.00mm)
• Number of rows: 2
• Row spacing - mating: 0.079" (2.00mm)
• Mounting type: Surface Mount
• Termination: Solder
• Fastening type: Push-Pull
• Contact finish - mating: Gold

Acceptable Variation Parameters:

• Operating temperature range (substitute may exceed minimum specification)
• Current rating (substitute may exceed minimum specification)
• Voltage rating (substitute may exceed minimum specification)
• Contact finish thickness (substitute may exceed minimum specification)
• Insulation height (minor tolerance variations acceptable)

The identified substitutes meet all primary matching criteria and maintain compatibility with existing PCB layouts and mating connectors.

Parameter Comparison

Engineering Selection Recommendations

Amphenol ICC 55510-110TRLF (Minitek® 2.00mm Series)

This substitute meets all primary matching criteria with enhanced electrical performance. The operating temperature range extends to 125°C, exceeding the original specification. Current rating of 2A and voltage rating of 200V both exceed the Molex part requirements. The contact finish thickness of 30.0µin provides increased durability compared to the original 15.0µin specification. RoHS compliance is confirmed. Packaging is supplied in Tape & Reel format with 2900 units in stock, providing superior availability.

Samtec S2M-105-02-F-D (Tiger Eye™ S2M Series)

This substitute maintains all critical mechanical and electrical parameters. The operating temperature range extends to 125°C. Current rating of 2.6A per contact exceeds the original 1.9A specification. ROHS3 compliance is confirmed. The insulation material is specified as Liquid Crystal Polymer (LCP) with contact material of Beryllium Copper. Packaging is supplied in Tube format with 821 units in stock.

Both substitutes are active products with confirmed RoHS compliance and unlimited moisture sensitivity rating. Selection between substitutes depends on packaging requirements (Tape & Reel versus Tube) and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 55510-110TRLF be used as a direct replacement for the Molex 0873811074?

A: Yes. Both connectors share identical pitch (0.079"), position count (10), row configuration (2 rows), mounting type (surface mount), and fastening mechanism (push-pull). The Amphenol part meets or exceeds all electrical specifications of the original part.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel packaging is optimized for automated assembly processes with continuous component feeding. Tube packaging is suitable for manual assembly or lower-volume applications. The Amphenol 55510-110TRLF is supplied in Tape & Reel format, while the Molex 0873811074 and Samtec S2M-105-02-F-D are supplied in Tube format.

Q: Are there differences in contact finish thickness between the substitutes?

A: Yes. The Molex 0873811074 specifies 15.0µin (0.38µm) gold plating on mating contacts. The Amphenol 55510-110TRLF specifies 30.0µin (0.76µm), providing increased contact durability. The Samtec S2M-105-02-F-D specifies 3.00µin (0.076µm). All three finishes are suitable for the specified voltage and current ratings.

Q: Do the substitutes support the same operating temperature range?

A: The Molex 0873811074 operates from -55°C to 105°C. Both substitute parts extend the upper operating limit to 125°C, providing additional thermal margin for demanding applications.

Q: What is the current rating difference between the parts?

A: The Molex 0873811074 is rated at 1.9A. The Amphenol 55510-110TRLF is rated at 2A. The Samtec S2M-105-02-F-D is rated at 2.6A per contact. All three ratings exceed typical application requirements for 2.00mm pitch connectors.

Q: Are all substitutes RoHS compliant?

A: Yes. The Molex 0873811074 is ROHS3 compliant. The Amphenol 55510-110TRLF is RoHS compliant. The Samtec S2M-105-02-F-D is ROHS3 compliant. All parts are REACH unaffected.
