MTSW-107-22-G-D-390 Equivalent & Substitute Parts

Part Overview

The MTSW-107-22-G-D-390 is a rectangular connector header manufactured by Samtec Inc. in the Flex Stack, MTSW series. This through-hole connector features 14 positions arranged in 2 rows with 0.100" (2.54mm) pitch, designed for board-to-board or cable applications. The part is currently active in production with 668 units in stock. Equivalent and substitute parts are identified based on matching electrical and mechanical specifications to ensure functional compatibility in applications requiring vertical header connectors with identical pitch, position count, and row configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MTSW-107-22-G-D-390 are qualified based on the following critical parameters that determine functional interchangeability:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for PCB footprint compatibility
• Number of Positions: 14 — determines contact count and mating interface
• Number of Rows: 2 — defines physical layout and spacing
• Row Spacing - Mating: 0.100" (2.54mm) — critical for board-to-board alignment
• Contact Type: Male Pin — ensures proper mating with female receptacles
• Mounting Type: Through Hole — determines PCB assembly method
• Termination: Solder — specifies connection method to PCB
• Fastening Type: Push-Pull — defines mechanical engagement mechanism
• Contact Finish - Mating: Gold — ensures electrical conductivity and corrosion resistance
• Material Flammability Rating: UL94 V-0 — meets safety compliance requirements

The 3M 929715-03-07-I and 929715-03-07-EU connectors meet all critical substitution criteria. Variations in contact length, insulation material composition, and operating temperature range do not prevent functional substitution when the above parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: MTSW-107-22-G-D-390 (Samtec Inc.)

The MTSW-107-22-G-D-390 is the recommended primary choice. It is actively produced, ROHS3 compliant, and offers the highest operating temperature range (-55°C ~ 125°C) and current rating (3A). This part provides the broadest application compatibility for demanding thermal and electrical environments.

Secondary Selection: 929715-03-07-I (3M)

The 929715-03-07-I qualifies as a direct functional substitute. It maintains active product status, RoHS compliance, and identical pitch, position count, and row configuration. The 3M part features higher inventory availability (1545 units). The reduced operating temperature range (-40°C ~ 105°C) and current rating (2.5A) are acceptable for applications within these specifications. The longer post length (0.410" vs. 0.140") accommodates deeper PCB stack-ups.

Tertiary Selection: 929715-03-07-EU (3M)

The 929715-03-07-EU is functionally equivalent to the 929715-03-07-I but carries discontinued status at DiGi Electronics. This part should be selected only when 929715-03-07-I is unavailable and application requirements fall within its operating specifications. Moisture sensitivity level is specified as 1 (Unlimited), matching the primary part.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929715-03-07-I replace the Samtec MTSW-107-22-G-D-390 in all applications?

A: The 929715-03-07-I is functionally compatible for applications operating within -40°C ~ 105°C and requiring maximum current of 2.5A. Applications requiring the extended temperature range (-55°C) or higher current (3A) of the MTSW-107-22-G-D-390 require verification that the 3M part meets specific design margins.

Q: What is the significance of the different contact lengths between these parts?

A: The MTSW-107-22-G-D-390 has a shorter post length (0.140") compared to the 3M parts (0.410"). This affects PCB stack-up depth. The Samtec part is suitable for standard PCB thicknesses, while the 3M parts accommodate thicker or multi-layer stack configurations. PCB design must account for these dimensional differences.

Q: Are the insulation materials interchangeable?

A: All three parts meet UL94 V-0 flammability requirements. The Samtec part uses Polyester with glass fill, while the 3M parts use PBT or PCT. These materials are functionally equivalent for electrical insulation and mechanical support in standard applications. Material selection does not affect electrical performance or mating compatibility.

Q: Why is the 929715-03-07-EU listed as discontinued?

A: The 929715-03-07-EU is discontinued at DiGi Electronics but remains functionally identical to the 929715-03-07-I. Discontinuation reflects distributor inventory decisions, not product deficiency. The 929715-03-07-I (active status) is the preferred 3M alternative.

Q: Does the lower current rating of the 3M parts affect compatibility?

A: The 3M parts are rated for 2.5A versus 3A for the Samtec part. Applications drawing less than 2.5A per contact are fully compatible. Applications requiring the full 3A rating must use the MTSW-107-22-G-D-390 or verify that the 3M part meets thermal and electrical margins for the specific current load.

Q: Are all three parts RoHS compliant?

A: Yes. The MTSW-107-22-G-D-390 is ROHS3 compliant. Both 3M parts are RoHS compliant. All three parts meet REACH requirements and carry EAR99 ECCN classification.
