Molex 0873811063 Equivalent & Substitute Parts

Part Overview

The Molex 0873811063 is a 10-position receptacle connector from the Milli-Grid 87381 series, designed for board-to-board applications with 0.079" (2.00mm) pitch spacing. This surface mount connector features gold-plated mating contacts, push-pull fastening, and operates across -55°C to 105°C. The part is active and in production with 998 units currently in stock.

Equivalent and substitute parts are identified when design requirements allow flexibility in connector series, packaging format, or when higher-rated specifications provide functional compatibility while maintaining critical electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0873811063 is determined by strict alignment of the following critical parameters:

Connector type: Receptacle with female socket contacts
Position count: 10 positions
Pitch spacing: 0.079" (2.00mm) mating pitch with 0.079" row spacing
Mounting: Surface mount with solder termination
Fastening: Push-pull mechanism
Contact finish: Gold plating on mating surface
Insulation: Black color
Style: Board-to-board configuration

The three identified substitute parts (55510-110LF, 55510-110TRLF, and S2M-105-02-F-D) meet all critical mechanical and electrical compatibility requirements. Differences in current rating, voltage rating, operating temperature range, and packaging format do not prevent functional substitution when application requirements fall within the substitute part specifications.

Engineering Selection Recommendations

All three substitute parts maintain active product status and full compliance with RoHS and REACH regulations. Selection between the Molex 0873811063 and its substitutes depends on application-specific requirements:

Amphenol ICC 55510-110LF and 55510-110TRLF provide higher current (2A) and voltage (200V) ratings with extended operating temperature range (-55°C to 125°C) compared to the Molex part. These Minitek® 2.00mm series connectors are functionally compatible for applications requiring enhanced electrical performance. The primary distinction between these two Amphenol parts is packaging: 55510-110LF is supplied in tube format, while 55510-110TRLF is supplied in tape and reel format for automated assembly processes.

Samtec S2M-105-02-F-D from the Tiger Eye™ S2M series offers the highest current rating (2.6A per contact) and supports both board-to-board and cable configurations. This part uses beryllium copper contacts with thinner gold plating (3.00µin) and liquid crystal polymer insulation material, providing alternative material construction while maintaining mechanical and electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use Amphenol ICC 55510-110LF as a direct replacement for Molex 0873811063?

A: Yes. Both parts share identical mechanical dimensions, pitch spacing (0.079"), position count (10), row configuration (2 rows), and fastening mechanism (push-pull). The Amphenol part exceeds the Molex specifications in current rating (2A vs. 1.9A), voltage rating (200V vs. 125V), and operating temperature range (-55°C to 125°C vs. -55°C to 105°C). Substitution is valid when application requirements fall within both part specifications.

Q: What is the difference between 55510-110LF and 55510-110TRLF?

A: These are identical Amphenol ICC Minitek® connectors with different packaging. The 55510-110LF is packaged in tube format for manual handling and lower-volume applications. The 55510-110TRLF is packaged in tape and reel format for automated pick-and-place assembly. Electrical and mechanical specifications are identical.

Q: Is the Samtec S2M-105-02-F-D compatible with the same mating connector as the Molex part?

A: The Samtec S2M-105-02-F-D maintains the same 0.079" (2.00mm) pitch spacing and 2-row configuration, ensuring mechanical compatibility with standard 2.00mm pitch plug connectors. However, contact material differences (beryllium copper vs. phosphor bronze) and insulation material differences (liquid crystal polymer vs. plastic) may affect specific performance characteristics in high-reliability applications.

Q: Which substitute part should I select for high-temperature applications?

A: Both Amphenol ICC parts (55510-110LF and 55510-110TRLF) and the Samtec S2M-105-02-F-D support operating temperatures up to 125°C, exceeding the Molex 0873811063 specification of 105°C. All three substitutes are suitable for extended temperature range applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Molex 0873811063 is ROHS3 compliant. Amphenol ICC parts are RoHS compliant. Samtec S2M-105-02-F-D is ROHS3 compliant. All parts meet regulatory requirements for lead-free and restricted substance compliance.
