HTST-112-01-S-DV Equivalent & Substitute Parts

Part Overview

The HTST-112-01-S-DV 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 and widely available in inventory. Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and application-specific requirements where alternative specifications may be acceptable.

Key Parameters

Substitute Part Grouping Explanation

The N2524-6V0C-RB-WE from 3M qualifies as a substitute for the HTST-112-01-S-DV based on the following critical parameters:

• Identical connector type (Header) and contact type (Male Pin)
• Matching position count (24) and row configuration (2 rows)
• Identical mating pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm)
• Equivalent mounting type (Surface Mount) and shrouding (Shrouded - 4 Wall)
• Matching fastening type (Push-Pull) and termination method (Solder)
• Identical contact finish on mating surface (Gold) with equivalent finish thickness (30.0µin / 0.76µm)
• Equivalent material flammability rating (UL94 V-0)
• RoHS compliance maintained

Substitution is valid where the mechanical and electrical interface requirements are met by these matching parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the HTST-112-01-S-DV and N2524-6V0C-RB-WE are active production parts with equivalent mechanical interfaces and compliance certifications. Selection between these parts should be based on the following factors:

The HTST-112-01-S-DV supports higher current per contact (3.4A versus 1.75A) and operates across a wider temperature range (-55°C to 125°C versus -55°C to 105°C). Applications requiring maximum current capacity or extended high-temperature operation should specify the Samtec part.

The N2524-6V0C-RB-WE is available in Tape & Reel packaging, which may be preferred for high-volume automated assembly processes compared to Tube packaging.

Both parts maintain UL94 V-0 flammability ratings and RoHS compliance. The choice between LCP and glass-filled PCT insulation materials depends on specific environmental and mechanical stress requirements of the application.

Frequently Asked Questions (FAQ)

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

A: Mechanical and electrical interface compatibility is established through matching pitch, position count, row configuration, shrouding, and fastening type. However, the lower current rating (1.75A versus 3.4A per contact) and narrower operating temperature range (-55°C to 105°C versus -55°C to 125°C) of the 3M part must be evaluated against application requirements.

Q: What are the key differences in insulation material?

A: The HTST-112-01-S-DV uses Liquid Crystal Polymer (LCP), while the N2524-6V0C-RB-WE uses glass-filled Polycyclohexylenedimethylene Terephthalate (PCT). Both materials achieve UL94 V-0 flammability ratings. Material selection should consider mechanical stress, thermal cycling, and chemical exposure specific to the application environment.

Q: Are there packaging considerations for production?

A: The HTST-112-01-S-DV is supplied in Tube packaging, while the N2524-6V0C-RB-WE is supplied in Tape & Reel format. Tape & Reel packaging is optimized for automated pick-and-place assembly, whereas Tube packaging may require manual handling or alternative feeder systems.

Q: How do the contact length specifications affect compatibility?

A: The mating contact lengths differ slightly (0.250" for Samtec versus 0.243" for 3M). This 0.007" difference is within typical tolerance ranges for standard 0.100" pitch connectors and does not affect mating compatibility. Insulation height also differs (0.350" versus 0.390"), which may impact board layout spacing in constrained designs.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant and carry UL94 V-0 material flammability ratings. The HTST-112-01-S-DV is ROHS3 compliant, while the N2524-6V0C-RB-WE is RoHS compliant. Both parts carry EAR99 ECCN classification and share the same HTSUS code (8536.69.4040).
