HTST-102-01-S-D Equivalent & Substitute Parts

Part Overview

The HTST-102-01-S-D is a rectangular connector header manufactured by Samtec Inc., classified within the Flex Stack and HTST series. This through-hole mounted connector features 4 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, designed for board-to-cable/wire applications. The component is currently in active production status with 952 pieces available in inventory. Identification of equivalent and substitute parts becomes necessary when addressing supply chain constraints, design revisions, or application-specific requirements that may benefit from alternative connector configurations while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTST-102-01-S-D is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm) — mechanical and electrical interface standard
• Connector Type: Header — functional role in board-to-cable/wire connections
• Contact Type: Male Pin — mating interface specification
• Mounting Type: Through Hole — PCB assembly method
• Termination: Solder — connection method to PCB
• Shrouding: Shrouded - 4 Wall — mechanical protection and keying alignment
• Contact Finish - Mating: Gold — electrical contact reliability
• Material Flammability Rating: UL94 V-0 — safety compliance requirement

Secondary Compatibility Considerations:

• Number of Positions and Row Configuration — application-dependent; substitutes may accommodate different position counts within the same pitch standard
• Operating Temperature Range — substitute must meet or exceed application requirements
• Current Rating — substitute must support application current demands
• RoHS Compliance Status — regulatory requirement alignment

The substitute part N2510-6002-RB from 3M meets the primary compatibility criteria with the following variance: it provides 10 positions in a 2-row configuration compared to the 4-position configuration of the main part. This substitution is valid for applications requiring expanded connectivity within the same mechanical and electrical interface standard.

Parameter Comparison

Engineering Selection Recommendations

Selection between the HTST-102-01-S-D and N2510-6002-RB must account for the following engineering factors:

Electrical Considerations: The N2510-6002-RB provides a reduced current rating of 1.75A per contact compared to 3.4A per contact for the HTST-102-01-S-D. Applications requiring current levels exceeding 1.75A per contact are not suitable for substitution with the 3M part.

Thermal Considerations: The HTST-102-01-S-D operates across -55°C to 125°C, while the N2510-6002-RB operates across -55°C to 105°C. Applications requiring operation above 105°C are not suitable for substitution with the 3M part.

Position Configuration: The N2510-6002-RB provides 10 positions versus 4 positions in the HTST-102-01-S-D. This substitution is applicable only when the application design accommodates or requires the expanded position count.

Compliance and Regulatory Status: Both parts maintain ROHS3 compliance and UL94 V-0 flammability rating, satisfying equivalent regulatory requirements. Both are active production components with established supply availability.

Material Composition: Contact material differs (Phosphor Bronze versus Copper Alloy) and insulation material differs (LCP versus PCT/Polyester/Glass Filled). These material variations do not preclude functional substitution within the specified electrical and thermal operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the N2510-6002-RB directly replace the HTST-102-01-S-D in all applications?

A: Direct replacement is not universal. The N2510-6002-RB differs in three critical parameters: position count (10 versus 4), maximum current rating per contact (1.75A versus 3.4A), and maximum operating temperature (105°C versus 125°C). Substitution is valid only when the application design accommodates these differences and does not exceed the reduced electrical or thermal specifications.

Q: What is the significance of the 0.100" (2.54mm) pitch specification?

A: Pitch defines the center-to-center spacing between adjacent contacts. Both parts share identical pitch and row spacing specifications, ensuring mechanical and electrical interface compatibility at the mating interface level. This is the primary criterion enabling substitution consideration.

Q: How do the different insulation materials affect performance?

A: The HTST-102-01-S-D uses Liquid Crystal Polymer (LCP) insulation, while the N2510-6002-RB uses Polycyclohexylenedimethylene Terephthalate (PCT) with polyester and glass filling. Both materials achieve UL94 V-0 flammability rating. Material selection does not preclude functional substitution when operating within specified temperature and electrical parameters.

Q: Why is the current rating difference significant?

A: Current rating defines the maximum continuous current each contact can safely conduct. The HTST-102-01-S-D supports 3.4A per contact, while the N2510-6002-RB supports 1.75A per contact. Applications designed for currents exceeding 1.75A per contact cannot use the 3M substitute without circuit redesign or parallel contact configuration.

Q: Are both parts suitable for high-temperature applications above 105°C?

A: Only the HTST-102-01-S-D is rated for operation above 105°C, extending to 125°C. The N2510-6002-RB is limited to 105°C maximum operating temperature. Applications requiring sustained operation between 105°C and 125°C must use the Samtec part.

Q: What packaging format is provided for each part?

A: The HTST-102-01-S-D packaging format is not specified in available documentation. The N2510-6002-RB is supplied in Tray packaging. Packaging format may influence procurement, handling, and assembly processes.

Q: Do both parts meet RoHS compliance requirements?

A: Both the HTST-102-01-S-D and N2510-6002-RB are ROHS3 compliant, satisfying equivalent regulatory requirements for restricted substance limitations.
