929647-05-25-EU Equivalent & Substitute Parts

Part Overview

The 929647-05-25-EU is a rectangular connector header manufactured by 3M, designed for through-hole board-to-board applications. This unshrouded, 25-position connector operates at 0.100" (2.54mm) pitch and supports a current rating of 2.5A across an operating temperature range of -40°C to 105°C. The part is actively produced and RoHS compliant, making it suitable for general industrial and consumer electronics applications where reliable interconnection is required.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, ensuring functional compatibility in target applications.

Key Parameters

Substitute Part Grouping Explanation

The Molex 0022284255 is identified as a manufacturer-recommended substitute based on the following critical parameters:

Matching Parameters:

• Connector type: Header, Breakaway
• Contact type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of positions: 25
• Number of rows: 1
• Mounting type: Through Hole
• Termination: Solder
• Fastening type: Push-Pull
• Contact finish - Mating: Gold
• Material flammability rating: UL94 V-0
• Insulation color: Black
• RoHS compliance: Compliant (ROHS3)
• Moisture sensitivity level: 1 (Unlimited)

These parameters define the functional and mechanical compatibility required for direct substitution in board-to-board interconnection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 929647-05-25-EU and 0022284255 are active products with equivalent RoHS compliance status. The 3M part carries explicit operating temperature and current rating specifications, while the Molex substitute provides these parameters implicitly through its series designation and active product status.

The Molex 0022284255 features a slightly higher gold plating thickness on mating contacts (15.0µin versus 10.0µin), which provides enhanced contact durability. The insulation material differs (polyamide glass-filled versus PCT), and the insulation height is marginally reduced (0.090" versus 0.100"), though both maintain UL94 V-0 flammability compliance.

Selection between these parts should be based on component availability, supply chain requirements, and specific PCB layout constraints related to the minor dimensional differences in insulation height and contact geometry.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022284255 directly replace the 3M 929647-05-25-EU in existing designs?

A: Yes, the Molex part is a manufacturer-recommended substitute with matching pitch (2.54mm), position count (25), connector type (header, breakaway), and contact configuration (male pin, through-hole solder termination). The core electrical and mechanical interfaces are equivalent.

Q: What are the dimensional differences between these parts?

A: The primary differences are insulation height (3M: 0.100" versus Molex: 0.090") and contact geometry. The Molex part features a shorter overall contact length (0.505" versus 0.945") and different post length specifications. These differences may affect PCB layout and mating connector selection.

Q: Are both parts RoHS compliant?

A: Yes. The 3M 929647-05-25-EU is RoHS Compliant, and the Molex 0022284255 is ROHS3 Compliant. Both meet current regulatory requirements for restricted substances.

Q: What is the difference in gold plating thickness?

A: The 3M part specifies 10.0µin (0.25µm) gold plating on mating contacts, while the Molex part specifies 15.0µin (0.38µm). The increased thickness on the Molex part provides additional contact durability and wear resistance.

Q: Do both parts support the same current rating?

A: The 3M part explicitly specifies 2.5A current rating. The Molex part does not provide an explicit current rating in the available specifications, though both are designed for general-purpose board-to-board interconnection applications.

Q: What insulation materials are used?

A: The 3M part uses Polycyclohexylenedimethylene Terephthalate (PCT), while the Molex part uses Polyamide (PA) with glass reinforcement. Both materials achieve UL94 V-0 flammability ratings and are suitable for industrial and consumer electronics applications.
