MTSW-109-08-G-D-215 Equivalent & Substitute Parts

Part Overview

The MTSW-109-08-G-D-215 is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 18-position, 2-row connector operates across a wide temperature range of -55°C to 125°C and is classified as an active product. The connector features a 0.100" (2.54mm) pitch with gold-plated phosphor bronze contacts rated for 3A current capacity. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate alternative suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSW-109-08-G-D-215 is determined by the following critical parameters:

• Connector Configuration: 18 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
• Contact Type: Male pin headers for board-to-board or cable connections
• Mounting Method: Through-hole solder termination
• Electrical Performance: Current rating and contact material compatibility
• Environmental Compliance: Operating temperature range, flammability rating, and RoHS status

The substitute part 929665-02-09-I from 3M meets the core dimensional and functional requirements of the MTSW-109-08-G-D-215. Both connectors share identical position counts, pitch specifications, and mounting characteristics. However, variations exist in contact length dimensions, current rating, operating temperature range, and contact material composition, which must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the MTSW-109-08-G-D-215 and 929665-02-09-I are active products with UL94 V-0 flammability ratings and RoHS compliance, making them suitable for equivalent applications in most industrial and commercial environments.

The MTSW-109-08-G-D-215 provides a wider operating temperature range (-55°C to 125°C) and higher current rating (3A) compared to the 929665-02-09-I (-40°C to 105°C, 2.5A). Applications requiring operation at temperatures below -40°C or above 105°C, or demanding current capacity exceeding 2.5A per contact, necessitate the Samtec part.

The 929665-02-09-I features a mating contact length of 0.235" (5.97mm) versus 0.215" (5.46mm) for the Samtec connector, resulting in a 0.020" difference in mating depth. This dimensional variation may affect board-to-board spacing and connector stack height in constrained layouts.

Both connectors employ gold-plated contacts with square geometry and identical pitch specifications, supporting direct mechanical and electrical interchangeability in applications where the operating temperature and current requirements of the 3M part are sufficient.

Frequently Asked Questions (FAQ)

Q: Can the 929665-02-09-I directly replace the MTSW-109-08-G-D-215 in all applications?

A: Direct replacement is possible for applications operating within -40°C to 105°C and requiring maximum current of 2.5A per contact. Applications exceeding these parameters require the MTSW-109-08-G-D-215.

Q: What is the significance of the contact length difference between these connectors?

A: The MTSW-109-08-G-D-215 has a mating contact length of 0.215" (5.46mm), while the 929665-02-09-I measures 0.235" (5.97mm). This 0.020" difference affects mating depth and overall connector stack height. PCB layouts and connector cavity designs must accommodate this variation.

Q: Are both connectors RoHS compliant?

A: Yes. The MTSW-109-08-G-D-215 is ROHS3 compliant, and the 929665-02-09-I is RoHS compliant. Both meet RoHS requirements for lead-free construction.

Q: What contact materials are used in each connector?

A: The MTSW-109-08-G-D-215 uses phosphor bronze contacts, while the 929665-02-09-I employs copper alloy contacts. Both are gold-plated with identical finish thickness on mating surfaces (10.0µin / 0.25µm).

Q: Do both connectors support the same pitch and row spacing?

A: Yes. Both connectors feature 0.100" (2.54mm) pitch and row spacing, with 18 positions arranged in 2 rows, ensuring mechanical compatibility in standard 0.100" grid applications.

Q: What is the current rating difference, and when does it matter?

A: The MTSW-109-08-G-D-215 is rated for 3A per contact, while the 929665-02-09-I is rated for 2.5A. Applications requiring sustained current above 2.5A per contact must use the Samtec connector.
