3M 929700-01-02 Equivalent & Substitute Parts

Part Overview

The 3M 929700-01-02 is a rectangular connector header designed for through-hole mounting applications. This 2-position, 0.100" (2.54mm) pitch connector features male pins with tin-lead plating and is rated for 2.5A continuous current. The part is currently active in production and widely used in board-to-board interconnect applications requiring standard pitch headers.

Substitute parts are necessary when the original part becomes unavailable, when alternative compliance certifications are required, or when enhanced electrical ratings or material specifications better suit specific application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 929700-01-02 is determined by the following critical parameters:

Number of Positions: Must be 2 positions
Pitch - Mating: Must be 0.100" (2.54mm)
Contact Type: Must be Male Pin
Mounting Type: Must be Through Hole
Termination: Must be Solder
Connector Style: Board to Board or Board to Board/Cable compatible

The three qualified substitute parts meet these core electrical and mechanical requirements while offering variations in material composition, contact finish, current rating, and compliance status. The 4-103321-0 is excluded from direct substitution due to its 40-position configuration, which is incompatible with the 2-position requirement of the main part.

Engineering Selection Recommendations

TE Connectivity 826648-2 is the primary substitute for applications requiring RoHS compliance and extended operating temperature range. This part maintains the same 2-position, 2.54mm pitch configuration with enhanced current rating (5A) and gold contact finish for improved corrosion resistance. The part is currently active and RoHS compliant, making it suitable for modern electronics manufacturing standards.

Amphenol ICC 68024-102HLF (BERGSTIK® II series) offers the highest current rating (5A) and gold contact finish with GXT™ technology. This part is RoHS compliant and active in production. The slightly increased overall contact length (0.568" vs. 0.528") must be evaluated for PCB layout compatibility.

TE Connectivity 4-103321-0 is not recommended as a direct substitute due to its 40-position configuration, which is mechanically and electrically incompatible with the 2-position requirement of the main part.

Frequently Asked Questions (FAQ)

Q: Can I use the TE Connectivity 826648-2 as a direct replacement for the 3M 929700-01-02?

A: Yes, the 826648-2 is mechanically and electrically compatible. Both parts share identical pitch (2.54mm), position count (2), contact type (male pin), and mounting method (through-hole solder). The 826648-2 offers higher current rating (5A vs. 2.5A) and RoHS compliance, making it suitable for direct substitution in most applications.

Q: What is the difference between tin-lead and gold contact finishes?

A: The 3M 929700-01-02 uses tin-lead plating (100.0µin thickness), while the TE Connectivity 826648-2 and Amphenol ICC 68024-102HLF use gold plating. Gold provides superior corrosion resistance and lower contact resistance, particularly beneficial in high-reliability or harsh environment applications. Gold-plated contacts are generally preferred for long-term storage and repeated mating cycles.

Q: Are there any PCB layout considerations when substituting these parts?

A: The overall contact length varies slightly among the three parts: 3M 929700-01-02 (0.528"), TE Connectivity 826648-2 (0.551"), and Amphenol ICC 68024-102HLF (0.568"). These differences may affect PCB hole depth and solder joint geometry. Verify that your PCB design accommodates the substitute part's contact length before implementation.

Q: Why is the 4-103321-0 listed as a substitute if it has 40 positions?

A: The 4-103321-0 is not a valid substitute for the 2-position 929700-01-02. This part appears in the original substitute list but does not meet the core substitution criteria due to its incompatible 40-position configuration. It should not be used as a replacement.

Q: What is the temperature operating range difference between parts?

A: The 3M 929700-01-02 operates from -40°C to 105°C, while the TE Connectivity 826648-2 extends the lower limit to -65°C. The Amphenol ICC 68024-102HLF does not specify an operating temperature range. For applications requiring operation below -40°C, the 826648-2 is the appropriate choice.

Q: Are all three parts UL94 V-0 rated?

A: Yes, all three parts carry UL94 V-0 material flammability rating, indicating compliance with flame retardancy requirements for electronic components.
