HTST-112-01-L-DV-TR Equivalent & Substitute Parts

Part Overview

The HTST-112-01-L-DV-TR is a surface mount rectangular connector header manufactured by Samtec Inc. in the Flex Stack series. This 24-position, 2-row connector with 0.100" (2.54mm) pitch is designed for board-to-cable/wire applications with push-pull fastening and shrouded 4-wall construction. The part is currently active in production with 1026 units in stock. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative connector solutions that maintain electrical and mechanical compatibility within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTST-112-01-L-DV-TR is determined by strict alignment with the following critical parameters:

Connector configuration must maintain 24 positions in a 2-row arrangement with 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing. The connector type must be a header with male pin contacts, surface mount mounting, and shrouded 4-wall construction. Fastening mechanism must be push-pull with solder termination. Operating temperature range must support the full -55°C to 125°C specification or a subset thereof. Material flammability rating must meet or exceed UL94 V-0. RoHS compliance status must be maintained at ROHS3 or equivalent level.

The identified substitute part N2524-6V0C-RB-WE from 3M meets these core substitution criteria while operating within acceptable parameter tolerances for this connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the HTST-112-01-L-DV-TR and N2524-6V0C-RB-WE are active production parts with full RoHS compliance and UL94 V-0 flammability certification. Selection between these parts should be based on application-specific operating temperature requirements. The Samtec HTST-112-01-L-DV-TR supports the full -55°C to 125°C temperature range, while the 3M N2524-6V0C-RB-WE operates within -55°C to 105°C. For applications requiring sustained operation above 105°C, the Samtec part is the appropriate choice. For applications within the 105°C maximum temperature envelope, either part is suitable. Both parts maintain identical connector geometry, pitch, row spacing, and fastening characteristics, ensuring mechanical and electrical interchangeability within their respective temperature ratings.

Frequently Asked Questions (FAQ)

Q: What determines if a connector can substitute for the HTST-112-01-L-DV-TR?

A: Substitute connectors must maintain 24 positions in a 2-row configuration with 0.100" (2.54mm) mating pitch and row spacing, surface mount mounting, shrouded 4-wall construction, push-pull fastening, solder termination, and UL94 V-0 flammability rating. Operating temperature range and RoHS compliance status must meet or exceed the original specification.

Q: Are there differences in current rating between the main part and substitute?

A: Yes. The HTST-112-01-L-DV-TR is rated at 3.4A per contact, while the N2524-6V0C-RB-WE is rated at 1.75A per contact. Applications requiring current levels above 1.75A per contact must use the Samtec part.

Q: What is the primary limitation of the 3M N2524-6V0C-RB-WE substitute?

A: The maximum operating temperature is 105°C, compared to 125°C for the Samtec part. Applications operating above 105°C require the original HTST-112-01-L-DV-TR.

Q: Are the contact finish specifications identical?

A: Both parts feature gold-plated mating contacts and tin-plated posts. The Samtec part specifies 10.0µin (0.25µm) gold thickness on mating contacts, while the 3M part specifies 30.0µin (0.76µm), providing enhanced corrosion resistance in the 3M option.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Yes, provided the application operates within the temperature and current constraints of the substitute part. Both connectors maintain identical pitch, row spacing, and mounting footprint for surface mount applications.
