Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSW-102-07-G-D-240 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, 4 positions arranged in 2 rows
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Contact Material & Finish: Gold-plated contacts for reliable mating
• Electrical Rating: Current capacity and operating temperature range
• Compliance: UL94 V-0 flammability and RoHS status

The substitute part 929665-01-02-I (3M) meets these core criteria with minor variations in contact length and material composition that do not affect functional interchangeability in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MTSW-102-07-G-D-240 and 929665-01-02-I maintain active product status with full RoHS compliance and UL94 V-0 flammability certification, supporting long-term design continuity. The Samtec part operates across a wider temperature range (-55°C to 125°C) and carries a higher current rating (3A versus 2.5A). The 3M substitute provides equivalent mechanical and electrical performance for applications operating within -40°C to 105°C and drawing up to 2.5A per contact. Contact length variations (0.240" versus 0.235" mating length) fall within standard manufacturing tolerances for 2.54mm pitch headers and do not affect PCB footprint compatibility. Selection between these parts should be based on specific application temperature requirements and current demands.

Frequently Asked Questions (FAQ)

Q: Can the 929665-01-02-I directly replace the MTSW-102-07-G-D-240 in all applications?

A: Direct replacement is suitable for applications operating within the 929665-01-02-I temperature range (-40°C to 105°C) and current requirements (2.5A maximum). Applications requiring the full -55°C to 125°C operating range or 3A current rating must use the MTSW-102-07-G-D-240.

Q: What are the key mechanical differences between these parts?

A: The primary differences are contact post length (0.090" versus 0.110") and overall contact length (0.430" versus 0.445"). Both parts maintain identical 0.100" (2.54mm) pitch and row spacing, ensuring PCB footprint compatibility. The mating contact length difference (0.240" versus 0.235") is within standard tolerance for this connector class.

Q: Are both parts suitable for high-reliability applications?

A: Both parts carry UL94 V-0 flammability certification and maintain active product status. The Samtec MTSW-102-07-G-D-240 offers extended temperature range coverage, while the 3M 929665-01-02-I provides equivalent reliability within its specified operating parameters.

Q: What is the difference in contact material between these parts?

A: The MTSW-102-07-G-D-240 uses phosphor bronze contacts, while the 929665-01-02-I uses copper alloy. Both materials are gold-plated with identical finish thickness (10.0µin at mating surface) and provide equivalent electrical performance for standard signal and power applications.

Q: Are there packaging or inventory considerations for these substitutes?

A: Both parts are supplied in bulk packaging. The MTSW-102-07-G-D-240 has 837 units in current inventory, while the 929665-01-02-I has 4122 units available, providing alternative sourcing options for supply chain management.
