HTST-105-04-L-D-LA Equivalent & Substitute Parts

Part Overview

The HTST-105-04-L-D-LA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-cable/wire applications. This shrouded 10-position connector operates across -55°C to 125°C and features kinked pin solder termination with push-pull fastening. The part is Active status and ROHS3 compliant, making it suitable for applications requiring reliable interconnection in industrial and commercial environments. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative connector options that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTST-105-04-L-D-LA is determined by strict alignment of the following critical parameters:

• Connector Type: Header (male pin contact type)
• Number of Positions and Rows: 10 positions, 2 rows
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Kinked Pin, Solder
• Fastening Type: Push-Pull
• Operating Temperature Range: -55°C ~ 125°C
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The identified substitutes TSS-105-04-L-D-LA and TST-105-04-L-D-LA meet all critical electrical and mechanical parameters. Variations in insulation material (Liquid Crystal Polymer vs. Polybutylene Terephthalate) and color do not affect functional compatibility in applications where the connector footprint, contact pitch, and electrical performance are the primary design constraints.

Parameter Comparison

Engineering Selection Recommendations

All three connector models—HTST-105-04-L-D-LA, TSS-105-04-L-D-LA, and TST-105-04-L-D-LA—are Active status products manufactured by Samtec Inc. and maintain ROHS3 compliance with UL94 V-0 flammability certification. These connectors are electrically and mechanically interchangeable for applications requiring 10-position, 2-row, 2.54mm pitch through-hole right-angle headers with push-pull fastening.

The primary distinction among these parts lies in insulation material composition. The HTST series utilizes Liquid Crystal Polymer (LCP) insulation with natural color, while both TSS and TST series employ Polybutylene Terephthalate (PBT) insulation with black color. The TST series specifically incorporates glass-filled PBT for enhanced mechanical rigidity. These material differences do not affect electrical performance or contact integrity in standard applications.

Selection between these substitutes should be based on inventory availability, lead time requirements, and any design-specific material preferences. All parts support the same operating temperature range (-55°C to 125°C) and contact current rating (3.4A per contact for HTST and TST; not specified for TSS).

Frequently Asked Questions (FAQ)

Q: Are TSS-105-04-L-D-LA and TST-105-04-L-D-LA direct replacements for HTST-105-04-L-D-LA?

A: Yes. All three connectors share identical electrical and mechanical specifications including pitch (2.54mm), position count (10), row configuration (2 rows), mounting type (through-hole right-angle), shrouding (4-wall), and termination method (kinked pin solder). They are functionally interchangeable in applications where these parameters define the design requirement.

Q: What is the difference between the insulation materials used in these connectors?

A: HTST-105-04-L-D-LA uses Liquid Crystal Polymer (LCP) insulation, while TSS-105-04-L-D-LA and TST-105-04-L-D-LA use Polybutylene Terephthalate (PBT). The TST variant incorporates glass-filled PBT for increased mechanical strength. These material variations do not impact electrical performance or contact reliability in standard operating conditions.

Q: Do all three parts meet the same compliance standards?

A: Yes. HTST-105-04-L-D-LA, TSS-105-04-L-D-LA, and TST-105-04-L-D-LA are all ROHS3 compliant and carry UL94 V-0 flammability certification. All are Active status products from Samtec Inc.

Q: Is the current rating the same across all three parts?

A: HTST-105-04-L-D-LA and TST-105-04-L-D-LA are rated for 3.4A per contact. The current rating for TSS-105-04-L-D-LA is not specified in the available data.

Q: Can these connectors be used interchangeably on the same PCB?

A: Yes, provided the PCB footprint accommodates the connector's physical dimensions. All three parts maintain identical contact pitch (2.54mm), row spacing (2.54mm), and mounting geometry (through-hole right-angle). Verify that the PCB layout supports the specific insulation height (0.365") and contact positioning of the selected substitute.

Q: What is the operating temperature range for these connectors?

A: All three connectors operate across -55°C to 125°C, making them suitable for industrial and commercial temperature environments.
