Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 787949-1 is determined by strict alignment with the following critical parameters: Connector Type (Firewire IEEE 1394), Number of Contacts (6), Gender (Plug), Mounting Type (Free Hanging In-Line), and Termination method (Solder). Additional compatibility factors include Operating Temperature Range (-55°C to 85°C), Shielding configuration (Unshielded), and Material Flammability Rating (UL94 V-0).

The 3M 3E206-0100KV meets all primary electrical and mechanical substitution criteria as a Firewire (IEEE 1394) Plug Connector with 6 positions, free hanging mounting, and solder termination. This part operates within the required temperature range and maintains the same shielding and flammability specifications.

The CEC Industries 928 is listed in the substitute field but does not meet the substitution criteria for the 787949-1. The 928 is a T-5 Wedge Lamp rated at 28V with 0.3A capacity and is categorized as a lighting component, not a Firewire connector. This part is not functionally or mechanically compatible with the IEEE 1394 connector application.

Parameter Comparison

Engineering Selection Recommendations

The 3M 3E206-0100KV is the only valid parametric equivalent for the TE Connectivity 787949-1. Both parts are active products with identical Firewire (IEEE 1394) connector specifications, 6-position configuration, plug gender, free hanging mounting, and solder termination. Both operate across the same temperature range (-55°C to 85°C) and maintain UL94 V-0 flammability compliance with unlimited moisture sensitivity rating.

A key difference exists in RoHS compliance status: the 3M 3E206-0100KV is ROHS3 compliant, while the TE Connectivity 787949-1 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements. The 3M part also provides higher voltage rating capability (150VAC/200VDC versus 40VAC), though the current rating is slightly lower (1A versus 1.5A).

The CEC Industries 928 is not a valid substitute. This part is a lighting component (T-5 Wedge Lamp) with fundamentally different electrical characteristics and application purpose. It cannot be used in place of the IEEE 1394 connector.

Frequently Asked Questions (FAQ)

Q: Can the 3M 3E206-0100KV directly replace the TE Connectivity 787949-1 in all applications?

A: The 3M 3E206-0100KV meets all primary electrical and mechanical substitution criteria for Firewire (IEEE 1394) connector applications. Both parts share identical connector type, contact count, gender, mounting configuration, and termination method. However, the current rating difference (1A versus 1.5A) must be evaluated against specific circuit requirements. Applications requiring the full 1.5A capacity of the original part may require design review.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The TE Connectivity 787949-1 is RoHS non-compliant, while the 3M 3E206-0100KV is ROHS3 compliant. RoHS compliance is a regulatory requirement in many markets, particularly the European Union. If your application or end-market requires RoHS compliance, the 3M part provides this certification while the TE Connectivity part does not.

Q: Why is the CEC Industries 928 listed as a substitute if it is not compatible?

A: The CEC Industries 928 is a lighting component (T-5 Wedge Lamp) and is not functionally compatible with the IEEE 1394 connector application. This part should not be considered for substitution in connector applications. The listing appears to be a data entry artifact and does not represent a valid engineering alternative.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: Connector Type (Firewire IEEE 1394), Number of Contacts (6), Gender (Plug), Mounting Type (Free Hanging In-Line), Termination method (Solder), Operating Temperature Range (-55°C to 85°C), Shielding (Unshielded), and Material Flammability Rating (UL94 V-0). Deviations in any of these parameters indicate incompatibility.

Q: How do the voltage and current ratings compare between the main part and substitute?

A: The TE Connectivity 787949-1 is rated for 40VAC at 1.5A. The 3M 3E206-0100KV is rated for 150VAC/200VDC at 1A. The 3M part provides higher voltage capability but lower current capacity. Circuit design must accommodate the 1A current limit of the substitute part.

Q: Are there packaging differences between these parts?

A: The TE Connectivity 787949-1 is supplied in unspecified packaging with 1011 pieces in stock. The 3M 3E206-0100KV is supplied in bulk packaging with 2100 pieces in stock. Packaging configuration may affect procurement and assembly processes.
