Molex 0873812484 Equivalent & Substitute Parts

Part Overview

The Molex 0873812484 is a 24-position receptacle connector from 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, push-pull fastening, and a current rating of 1.9A per contact at 125V. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are necessary when the original Molex part is unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility permits selection from qualified alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0873812484 are qualified based on the following critical parameters that must match or exceed the original specification:

Mandatory Matching Parameters:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 24
• 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
• Insulation color: Black
• Insulation height: 0.177" (4.50mm)
• Contact shape: Square

Allowable Variations:

• Packaging format: Tube or Tape & Reel (TR)
• Operating temperature range: May extend beyond -55°C ~ 105°C
• Current rating: May exceed 1.9A per contact
• Contact finish thickness - mating: May vary
• Features: Board guide and/or pick and place capabilities may be added
• Insulation material: May differ if mechanical compatibility is maintained

All substitute parts listed are from Samtec Inc., series MMS, and maintain full compatibility with the Molex 0873812484 in terms of mating interface, electrical performance, and mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active production items with ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the original Molex 0873812484.

Packaging Selection:

Tube packaging (MMS-112-02-F-DV, MMS-112-02-F-DV-A, MMS-112-02-L-DV-K, MMS-112-02-L-DV-P) is suitable for manual assembly, prototyping, and lower-volume production runs. Tape & Reel packaging (MMS-112-02-L-DV-K-TR, MMS-112-02-L-DV-A-K-TR) is required for automated pick-and-place assembly processes and high-volume manufacturing.

Feature Considerations:

Parts designated with "-A" suffix (MMS-112-02-F-DV-A, MMS-112-02-L-DV-A-K-TR) include board guide features. Parts designated with "-K" or "-P" suffix include pick-and-place features. The original Molex part includes both board guide and pick-and-place capabilities; substitute selection should match these features based on assembly process requirements.

Performance Headroom:

All Samtec MMS-112 substitutes provide 3.9A per contact current rating, exceeding the original 1.9A specification. Operating temperature range extends to 125°C compared to the original 105°C maximum, providing additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Are all listed parts mechanically compatible with the Molex 0873812484?

A: Yes. All substitute parts maintain identical mating pitch (0.079"), row spacing (0.079"), number of positions (24), and contact geometry. They are designed for direct mechanical interchange in board-to-board applications.

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

A: Tube packaging contains loose components suitable for manual handling and small-quantity assembly. Tape & Reel packaging presents components in a continuous carrier tape wound on a reel, required for automated pick-and-place assembly equipment used in high-volume production.

Q: Can I substitute a part with board guide features for one without?

A: Board guide features provide mechanical alignment assistance during mating. Substitution is possible if your application does not require this alignment aid, but adding board guide features when not originally specified may affect PCB layout requirements.

Q: Do all substitutes meet the same electrical specifications?

A: All substitutes meet or exceed the original electrical specifications. They share identical contact finish (gold), fastening type (push-pull), and termination method (solder). Current rating is higher (3.9A vs. 1.9A), and operating temperature range is extended (-55°C to 125°C vs. -55°C to 105°C).

Q: Are there compliance differences between the original and substitute parts?

A: No. All parts listed are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent across all options.

Q: Which substitute should I select for automated assembly?

A: Select either MMS-112-02-L-DV-K-TR or MMS-112-02-L-DV-A-K-TR, both supplied in Tape & Reel format. Choose the "-A" variant if board guide features are required for your application.
