Engineering Selection Recommendations

The MTSW-105-24-G-D-250-LL maintains active product status with full manufacturing support from Samtec Inc. The connector achieves ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. The through-hole termination with kinked pin design provides robust mechanical retention for PCB assembly processes. The 3A current rating and -55°C to 125°C operating temperature range establish suitability for standard industrial control and instrumentation applications. Selection of equivalent parts should prioritize maintenance of all specified electrical, mechanical, and material parameters to ensure functional interchangeability within existing circuit designs and PCB layouts.

Frequently Asked Questions (FAQ)

Q: What determines if a connector can substitute for the MTSW-105-24-G-D-250-LL?

A: Substitution requires identical specifications across contact type, position count, row configuration, mating pitch, row spacing, mounting method, termination style, contact dimensions, contact materials, finish specifications, current rating, and operating temperature range. Deviations in any of these parameters result in incompatibility.

Q: Can connectors with different pitch spacing be used as substitutes?

A: No. The MTSW-105-24-G-D-250-LL specifies 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing. Connectors with alternative pitch values are not compatible with existing PCB layouts and cannot serve as substitutes.

Q: Are through-hole and surface-mount variants interchangeable?

A: No. The MTSW-105-24-G-D-250-LL is exclusively through-hole mounted with kinked pin solder termination. Surface-mount alternatives require different PCB design and assembly processes and are not substitutable.

Q: Does the contact finish specification affect substitution eligibility?

A: Yes. The MTSW-105-24-G-D-250-LL specifies gold plating on both mating and post contacts. Connectors with alternative finishes (tin, nickel, or bare copper) present different electrical and corrosion characteristics and cannot be substituted.

Q: What is the significance of the UL94 V-0 flammability rating?

A: The UL94 V-0 rating indicates the insulation material meets stringent flame propagation requirements. Substitutes must maintain this certification to comply with safety standards in regulated applications.

Q: Is ROHS3 compliance mandatory for substitution?

A: Yes. The MTSW-105-24-G-D-250-LL is ROHS3 compliant. Substitutes must maintain equivalent compliance status to meet environmental and regulatory requirements in target markets.

Q: Can the connector be used in applications exceeding 3A current?

A: No. The 3A current rating is the maximum continuous current specification. Applications requiring higher current capacity require alternative connector designs with higher current ratings.

Q: What is the operational temperature range limitation?

A: The connector operates within -55°C to 125°C. Applications requiring operation outside this range require alternative connector designs with extended temperature specifications.
