Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HTST-107-01-SM-DV are qualified based on strict alignment of the following critical parameters:

• Connector type (Header) and contact type (Male Pin)
• Position count (14) and row configuration (2 rows)
• Mating pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm)
• Mounting technology (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Termination method (Solder)
• Contact finish (Gold mating surface)
• Flammability compliance (UL94 V-0)
• Moisture sensitivity level (MSL 1)
• RoHS compliance status

The identified substitutes—AWHW 14G-SMD (Assmann WSW Components) and N2514-6V0C-RB-WD (3M)—meet these core mechanical and electrical compatibility criteria. Variations in contact material, insulation material, contact length, and operating temperature ranges are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with RoHS and MSL 1 requirements, supporting long-term design viability and supply chain stability.

The HTST-107-01-SM-DV (Samtec) offers the widest operating temperature range (-55°C ~ 125°C) and highest current rating per contact (3.4A), making it suitable for applications requiring extended thermal performance and higher current density.

The AWHW 14G-SMD (Assmann WSW Components) provides a direct mechanical alternative with comparable current rating (3A) and operating temperature range (-40°C ~ 105°C). The flash gold finish on mating contacts and polyamide insulation material represent acceptable variations for standard industrial applications. Tube packaging aligns with the primary part.

The N2514-6V0C-RB-WD (3M, 2500 series) maintains full mechanical compatibility and temperature range (-55°C ~ 105°C) matching the lower bound of the primary part. The current rating (1.75A per contact) is reduced compared to the primary part and should be evaluated against application requirements. Tape & Reel packaging supports high-volume automated assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can AWHW 14G-SMD be used as a direct replacement for HTST-107-01-SM-DV?

A: Yes, within the specified operating temperature range of -40°C ~ 105°C. The AWHW 14G-SMD maintains identical pitch (0.100" / 2.54mm), position count (14), row configuration (2), shrouding (4-wall), and fastening mechanism (push-pull). Contact length variation (0.232" vs. 0.250") and insulation material difference (polyamide vs. LCP) are mechanical tolerances that do not affect mating compatibility. Current rating (3A) is acceptable for most applications below the 3.4A specification of the primary part.

Q: What are the limitations of N2514-6V0C-RB-WD as a substitute?

A: The N2514-6V0C-RB-WD maintains full mechanical and thermal compatibility (-55°C ~ 105°C). The primary limitation is reduced current rating per contact (1.75A vs. 3.4A). Applications requiring current density above 1.75A per contact should not use this substitute. Tape & Reel packaging differs from tube packaging of the primary part, affecting procurement and handling workflows.

Q: Are there differences in contact finish that affect signal integrity?

A: All three parts feature gold mating contact finish. The HTST-107-01-SM-DV and N2514-6V0C-RB-WD specify 30.0µin (0.76µm) gold thickness, while AWHW 14G-SMD specifies flash gold finish. Flash finish provides adequate corrosion protection and contact resistance for standard signal and power applications. For high-reliability or high-frequency applications, the specified 30.0µin thickness may be preferred.

Q: How do insulation material differences impact thermal performance?

A: The HTST-107-01-SM-DV uses Liquid Crystal Polymer (LCP), while AWHW 14G-SMD uses glass-filled polyamide (PA9T) and N2514-6V0C-RB-WD uses glass-filled PCT. All materials meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and lower moisture absorption. Polyamide and PCT are established alternatives with acceptable thermal and mechanical properties within the specified operating ranges. Material selection should be evaluated against specific application requirements for thermal cycling, humidity exposure, and dimensional tolerance needs.

Q: What packaging considerations apply to substitute selection?

A: HTST-107-01-SM-DV and AWHW 14G-SMD are supplied in tube packaging, suitable for manual handling and lower-volume assembly. N2514-6V0C-RB-WD is supplied in Tape & Reel format, optimized for automated pick-and-place assembly and high-volume production. Packaging selection should align with assembly process capabilities and volume requirements.
