Molex 0873815064 Equivalent & Substitute Parts

Part Overview

The Molex 0873815064 is a 50-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, gold-plated mating contacts, and push-pull fastening. The part is active and in production with 672 units currently in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct functional replacement in compatible applications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by alignment in the following critical parameters:

Connector type (receptacle vs. header configuration)
Position count (50 positions)
Mating pitch (0.079" / 2.00mm)
Row configuration (2 rows with 0.079" spacing)
Mounting method (surface mount)
Fastening mechanism (push-pull)
Contact finish (gold plating)
Operating temperature range (-55°C ~ 105°C minimum)
Termination method (solder)
Compliance status (RoHS3)

The substitute parts listed below meet these core criteria. Variations in secondary parameters such as contact finish thickness, insulation height, current rating, and voltage rating are noted but do not preclude functional substitution when application requirements permit.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with RoHS requirements. Selection between substitutes depends on application-specific constraints:

The 3M 150250-2000-RB and 150250-2020-RB-WF are receptacle connectors matching the Molex 0873815064 connector type. The 150250-2020-RB-WF variant includes board guide and pick-and-place features and is available in higher quantity (1885 units). Both 3M parts support higher voltage ratings (500VDC) compared to the main part (125V).

The Sullins NPPN252FFKP-RC and NPPN252FFKS-RC are header connectors rather than receptacles. These parts support higher current ratings (2A vs. 1.9A) and operate across a narrower temperature range (-40°C to 105°C vs. -55°C to 105°C). The NPPN252FFKP-RC includes board guide features.

Connector type compatibility must be verified in the mating application. Receptacle-to-receptacle or header-to-header pairing is required for proper mechanical and electrical engagement.

Frequently Asked Questions (FAQ)

Q: Can the 3M 150250-2000-RB directly replace the Molex 0873815064?

A: Both are 50-position receptacle connectors with 0.079" pitch, 2-row configuration, surface mount termination, and push-pull fastening. Mechanical and electrical compatibility is established for these core parameters. Verify application voltage and current requirements against the 3M part's 500VDC / 1A rating.

Q: What is the difference between the two 3M substitute parts?

A: The 150250-2020-RB-WF includes board guide and pick-and-place features and is supplied in cut tape packaging. The 150250-2000-RB is supplied in bulk packaging without these features. Both share identical electrical and mechanical specifications.

Q: Why are the Sullins parts listed as substitutes if they are headers, not receptacles?

A: The Sullins NPPN252FFKP-RC and NPPN252FFKS-RC meet all core substitution criteria: 50 positions, 0.079" pitch, 2-row configuration, surface mount, push-pull fastening, and gold-plated contacts. However, connector type (header vs. receptacle) determines mating compatibility. These parts substitute only in applications where header connectors are acceptable.

Q: What is the operating temperature difference between the main part and Sullins substitutes?

A: The Molex 0873815064 operates from -55°C to 105°C. The Sullins NPPN252FFKP-RC and NPPN252FFKS-RC operate from -40°C to 105°C. Applications requiring operation below -40°C must use the Molex or 3M parts.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Molex 0873815064 is ROHS3 compliant. The 3M parts are RoHS compliant. The Sullins parts are ROHS3 compliant. All meet regulatory requirements for restricted substance elimination.

Q: Which substitute part has the highest current rating?

A: The Sullins NPPN252FFKP-RC and NPPN252FFKS-RC both support 2A, compared to 1.9A for the Molex part and 1A for the 3M parts. Application current requirements should guide selection.
