Molex 0873812474 Equivalent & Substitute Parts

Part Overview

The Molex 0873812474 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, gold-plated mating contacts, and push-pull fastening. The part is active in production and ROHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical and mechanical parameters: connector type (receptacle), contact configuration (24-position female socket), pitch (0.079"), mounting method (surface mount), termination (solder), and fastening type (push-pull). Substitutes must maintain compatibility within the specified operating temperature and voltage ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0873812474 are qualified based on the following matching criteria:

Primary Matching Parameters:

• Connector type: Receptacle
• Contact configuration: 24-position female socket
• Pitch: 0.079" (2.00mm)
• Row spacing: 0.079" (2.00mm)
• Mounting: Surface mount
• Termination: Solder
• Fastening: Push-pull
• Contact finish: Gold

Acceptable Variation Parameters:

• Operating temperature range (substitute must cover or exceed the -55°C to 105°C range)
• Current rating (substitute must meet or exceed 1.9A requirement)
• Voltage rating (substitute must meet or exceed 125V requirement)
• Contact finish thickness (minor variations acceptable)
• Insulation material and color (functional equivalence maintained)
• Packaging format (tube or tape & reel both acceptable)

All substitute parts listed maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

Hirose A3 Series (A3-24DA-2SV(71), A3A-24DA-2SV(71)): These parts meet the core mechanical and electrical requirements with 24-position 0.079" pitch surface mount configuration. Both are ROHS3 compliant and active in production. The A3A-24DA-2SV(71) variant includes board guide features. Note that the operating temperature range is limited to -55°C ~ 85°C, which is narrower than the Molex part. Current rating is 1A, which is lower than the Molex 1.9A specification.

Samtec Tiger Eye™ SMM Series (SMM-112-02-F-D, SMM-112-02-L-D, SMM-112-02-S-D-K-TR, SMM-112-02-S-D-LC, SMM-112-02-S-D-P-TR, SMM-112-02-S-D-TR): All Samtec variants maintain full mechanical compatibility with 24-position 0.079" pitch configuration and exceed electrical specifications with 3.2A per contact and 350VAC rating. Operating temperature extends to 125°C, covering the full Molex range. All are ROHS3 compliant and active in production. Variants differ in packaging (tube vs. tape & reel) and features (board lock, pick and place capability). The SMM-112-02-S-D-P-TR offers the highest inventory availability at 2290 pieces.

Packaging Considerations: Tube packaging (standard) is suitable for manual assembly and lower-volume applications. Tape & reel packaging is optimized for automated pick-and-place assembly and high-volume production.

Frequently Asked Questions (FAQ)

Q: Can I use Hirose A3 series connectors as direct replacements for the Molex 0873812474?

A: The Hirose A3 series maintains mechanical compatibility with matching 24-position 0.079" pitch configuration and push-pull fastening. However, the operating temperature range (-55°C ~ 85°C) is narrower than the Molex part (-55°C ~ 105°C), and the current rating (1A) is lower than the Molex specification (1.9A). Selection depends on your application's actual temperature and current requirements.

Q: What are the key differences between Samtec SMM-112 variants?

A: All Samtec SMM-112 variants share identical electrical and mechanical specifications (24-position, 0.079" pitch, 3.2A, 350VAC, -55°C ~ 125°C). Differences are in packaging format (tube vs. tape & reel) and optional features: SMM-112-02-L-D has no special features, SMM-112-02-S-D-LC includes board lock, and SMM-112-02-S-D-K-TR and SMM-112-02-S-D-P-TR include pick-and-place features. Tape & reel variants are designated with "-TR" suffix.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and maintain unlimited moisture sensitivity rating (MSL 1), matching the Molex 0873812474 compliance status.

Q: Which substitute offers the best electrical margin?

A: The Samtec Tiger Eye™ SMM series provides the highest electrical margin with 3.2A per contact (versus 1.9A requirement) and 350VAC rating (versus 125V requirement). These parts also extend the operating temperature range to 125°C.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging is standard for manual assembly and lower-volume applications. Tape & reel packaging is configured for automated pick-and-place assembly equipment and is preferred for high-volume production runs. Both packaging formats contain the same connector components.
