MTSW-112-07-L-D-150 Equivalent & Substitute Parts

Part Overview

The MTSW-112-07-L-D-150 is a rectangular connector header manufactured by Samtec Inc. in the Flex Stack, MTSW series. This through-hole mounted connector features 24 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. Equivalent and substitute parts may be required due to supply chain considerations, design revisions, or application-specific requirements where alternative contact geometries or insulation materials are acceptable within electrical and mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSW-112-07-L-D-150 is determined by the following critical parameters:

• Connector type (Header, Male Pin)
• Number of positions (24) and row configuration (2 rows)
• Mating pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole) and termination (Solder)
• Fastening mechanism (Push-Pull)
• Contact material (Phosphor Bronze)
• Current rating (3A minimum)
• Flammability compliance (UL94 V-0)
• RoHS3 compliance

Variations in contact length, insulation height, contact finish thickness, and operating temperature range are permissible provided the substitute maintains mechanical and electrical compatibility with mating connectors designed for 0.100" pitch, 24-position headers.

Parameter Comparison

Engineering Selection Recommendations

The MTSW-112-07-L-D-150 (Samtec) is the primary specification for new designs due to its active production status and extended upper operating temperature limit of 125°C.

The 1-87227-2 (TE Connectivity AMP Connectors) is electrically and mechanically compatible for applications where the following conditions are met:

• Operating temperature does not exceed 105°C
• PCB layout accommodates the increased overall contact length of 0.533" (14.65mm) versus 0.430" (10.92mm)
• PCB layout accommodates the reduced insulation height of 0.090" (2.29mm) versus 0.100" (2.54mm)
• Post finish material (Gold) is acceptable in place of Tin
• Insulation material (Thermoplastic) is acceptable in place of Polyester, Glass Filled

The 1-87227-2 is discontinued at DiGi Electronics and should not be specified for new production designs. It may be considered only for legacy system maintenance or repair where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can the 1-87227-2 be used as a direct replacement for the MTSW-112-07-L-D-150 in new designs?

A: No. The 1-87227-2 is discontinued at DiGi Electronics. The MTSW-112-07-L-D-150 is the recommended specification for new designs. The substitute part differs in contact length geometry, insulation height, post finish material, insulation material composition, and maximum operating temperature.

Q: What are the critical compatibility parameters for these connectors?

A: Both connectors share identical specifications for connector type, contact type, position count, row configuration, mating pitch, row spacing, mounting method, termination, fastening mechanism, contact material, current rating, and flammability compliance. Differences exist in contact geometry, insulation properties, and operating temperature range.

Q: Will the 1-87227-2 mate with connectors designed for the MTSW-112-07-L-D-150?

A: Mating compatibility depends on the mating connector design. Both parts have identical mating pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm). However, the 1-87227-2 has a longer overall contact length (0.533" versus 0.430"), which may affect mating depth and connector engagement. Verify mating connector specifications before substitution.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the MTSW-112-07-L-D-150 and 1-87227-2 are ROHS3 compliant.

Q: What is the difference in post finish material, and does it affect performance?

A: The MTSW-112-07-L-D-150 uses Tin post finish, while the 1-87227-2 uses Gold post finish. Both materials are suitable for solder termination. Gold provides superior corrosion resistance; Tin is standard for general-purpose applications. Selection depends on environmental exposure and solderability requirements.

Q: Can the 1-87227-2 be used in applications with operating temperatures above 105°C?

A: No. The 1-87227-2 is rated for -65°C ~ 105°C. The MTSW-112-07-L-D-150 is rated for -55°C ~ 125°C. For applications exceeding 105°C, the MTSW-112-07-L-D-150 is required.
