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

Part Overview

The HTST-112-01-T-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 946 units in stock. Alternative equivalent parts may be required due to supply constraints, design revisions, or specific application requirements where substitute connectors meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HTST-112-01-T-DV-TR is permissible with parts that maintain the following critical parameters:

• 24-position, 2-row configuration
• 0.100" (2.54mm) mating pitch and row spacing
• Surface mount solder termination
• Shrouded 4-wall construction
• Push-pull fastening mechanism
• Operating temperature range of -55°C ~ 105°C minimum
• UL94 V-0 flammability rating
• RoHS compliance

The N2524-6V0C-RB-WE from 3M meets these core substitution criteria. Variations in contact finish, insulation material, contact length tolerances, and current rating specifications are secondary parameters that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the HTST-112-01-T-DV-TR and N2524-6V0C-RB-WE are active production parts with UL94 V-0 flammability ratings and RoHS compliance. The primary distinction lies in current-carrying capacity: the Samtec part supports 3.4A per contact, while the 3M substitute supports 1.75A per contact. Selection between these parts must be based on the application's current requirements per contact. The N2524-6V0C-RB-WE features gold-plated mating contacts and glass-filled PCT insulation, whereas the HTST-112-01-T-DV-TR uses tin-plated contacts and LCP insulation. Minor variations in contact length and insulation height exist within tolerance ranges typical for this connector class.

Frequently Asked Questions (FAQ)

Q: Can the N2524-6V0C-RB-WE directly replace the HTST-112-01-T-DV-TR in existing designs?

A: Direct mechanical and electrical substitution is possible if the application current requirement per contact does not exceed 1.75A. The lower current rating of the 3M part is the primary limiting factor. Pitch, row spacing, mounting footprint, and connector interface are equivalent.

Q: What are the differences in contact finish between these parts?

A: The HTST-112-01-T-DV-TR uses tin plating on mating contacts, while the N2524-6V0C-RB-WE uses gold plating (30.0µin thickness). Gold plating provides enhanced corrosion resistance and lower contact resistance, which may be beneficial in high-reliability or harsh environment applications.

Q: Are there packaging differences between these connectors?

A: Both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly. The HTST-112-01-T-DV-TR has 946 units in stock, while the N2524-6V0C-RB-WE has 1584 units available.

Q: Do both parts meet the same temperature and compliance requirements?

A: Yes. Both parts operate across -55°C to 105°C, carry UL94 V-0 flammability ratings, and meet RoHS compliance standards. The HTST-112-01-T-DV-TR is ROHS3 compliant, while the N2524-6V0C-RB-WE is RoHS compliant.

Q: What is the significance of the insulation material difference?

A: The HTST-112-01-T-DV-TR uses Liquid Crystal Polymer (LCP) insulation, while the N2524-6V0C-RB-WE uses glass-filled Polycyclohexylenedimethylene Terephthalate (PCT). Both materials meet UL94 V-0 requirements. LCP offers superior dimensional stability and lower moisture absorption, while glass-filled PCT provides enhanced mechanical strength.
