HTST-107-01-F-DV Equivalent & Substitute Parts

Part Overview

The HTST-107-01-F-DV is a surface mount rectangular connector header manufactured by Samtec Inc. within the Flex Stack HTST series. This 14-position, 2-row connector with 0.100" (2.54mm) pitch is designed for board-to-cable/wire applications requiring push-pull fastening and shrouded 4-wall construction. The part is currently active in production with 672 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement in circuit designs.

Substitute Part Grouping Explanation

The HTST-107-01-T-DV qualifies as a direct substitute for the HTST-107-01-F-DV based on the following critical parameters:

Matching Parameters:

Connector type, contact type, and gender (Header, Male Pin)
Position count and row configuration (14 positions, 2 rows)
Pitch specifications (0.100" mating pitch, 0.100" row spacing)
Mounting method (Surface Mount)
Shrouding design (Shrouded - 4 Wall)
Fastening mechanism (Push-Pull)
Contact material (Phosphor Bronze)
Insulation material (Liquid Crystal Polymer)
Current rating (3.4A per Contact)
Flammability rating (UL94 V-0)
RoHS compliance (ROHS3 Compliant)
Series designation (Flex Stack, HTST)

Differing Parameters:

Contact finish - mating surface (Gold vs. Tin)
Operating temperature upper limit (-55°C ~ 125°C vs. -55°C ~ 105°C)
Moisture sensitivity level (Not Applicable vs. 1 - Unlimited)

These differences do not prevent functional substitution in applications where the operating temperature does not exceed 105°C and where contact finish material compatibility is acceptable.

Engineering Selection Recommendations

Both HTST-107-01-F-DV and HTST-107-01-T-DV are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts depends on application-specific requirements:

The HTST-107-01-F-DV with gold-plated mating contacts is suitable for applications requiring enhanced corrosion resistance and contact reliability across the full -55°C to 125°C operating range.

The HTST-107-01-T-DV with tin-plated mating contacts is suitable for applications with operating temperatures not exceeding 105°C. This variant has higher inventory availability (1700 units vs. 672 units).

Both parts share identical mechanical footprints, electrical ratings, and connector geometry, ensuring PCB layout compatibility and interchangeability within the specified thermal constraints.

Frequently Asked Questions (FAQ)

Q: Can HTST-107-01-T-DV replace HTST-107-01-F-DV in all applications?

A: Substitution is valid when the application's maximum operating temperature does not exceed 105°C. The HTST-107-01-F-DV supports operation to 125°C; the HTST-107-01-T-DV is rated to 105°C. Contact finish material (gold vs. tin) may affect long-term reliability in high-humidity or corrosive environments; verify compatibility with your application requirements.

Q: What is the difference between gold and tin contact finishes?

A: Gold plating provides superior corrosion resistance and is typically specified for applications requiring extended shelf life or exposure to corrosive atmospheres. Tin plating is suitable for standard industrial applications with controlled environmental conditions. Both finishes meet the current rating of 3.4A per contact.

Q: Are the PCB footprints identical between these two parts?

A: Yes. Both parts share identical pitch (0.100"), row spacing (0.100"), mounting type (Surface Mount), and physical dimensions. PCB layouts are fully interchangeable.

Q: What does the keying slot feature provide?

A: The keying slot prevents incorrect mating orientation, ensuring proper connector alignment during assembly and reducing installation errors.

Q: Are both parts RoHS compliant?

A: Yes. Both HTST-107-01-F-DV and HTST-107-01-T-DV are ROHS3 compliant and carry EAR99 export classification.
