HTMS-140-02-G-D Equivalent & Substitute Parts

Part Overview

The HTMS-140-02-G-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board applications. This unshrouded header features 80 positions arranged in 2 rows with 0.050" (1.27mm) pitch and push-pull fastening. The connector is actively produced and widely used in applications requiring reliable solder termination and high current capacity per contact.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct replacement in compatible designs without circuit modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTMS-140-02-G-D is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - Mating (0.050" / 1.27mm)
• Number of positions (80)
• Number of rows (2)
• Row spacing - Mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact shape (Square)
• Shrouding configuration (Unshrouded)
• Material flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The substitute part 6-103916-6 (TE Connectivity AMP Connectors) meets all critical electrical and mechanical parameters required for direct substitution in board-to-board applications with identical pitch, position count, row configuration, and fastening mechanism.

Parameter Comparison

Engineering Selection Recommendations

Both the HTMS-140-02-G-D and 6-103916-6 are active production parts with ROHS3 compliance and UL94 V-0 flammability ratings. The primary distinction lies in operating temperature range: the Samtec part supports -55°C to 125°C, while the TE Connectivity part supports -65°C to 105°C. Selection should be based on the specific thermal requirements of the application. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can 6-103916-6 be used as a direct replacement for HTMS-140-02-G-D?

A: Yes, for applications within the overlapping temperature range of -55°C to 105°C. Both connectors share identical pitch (0.050"), position count (80), row configuration (2 rows), and fastening mechanism (push-pull). Verify your application's operating temperature requirements before selection.

Q: What are the key differences between these two connectors?

A: The primary differences are insulation material (LCP vs. Thermoplastic), contact material (Phosphor Bronze vs. Copper Alloy), contact finish on posts (Gold vs. Tin), and operating temperature ranges. Electrical and mechanical compatibility for board-to-board mating is maintained.

Q: Are both parts suitable for high-current applications?

A: The HTMS-140-02-G-D specifies 5A per contact current rating. The 6-103916-6 does not provide a current rating specification in available documentation. Confirm current requirements with the TE Connectivity datasheet for your specific application.

Q: Do these connectors require special handling or storage?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Standard component storage practices apply.

Q: What is the pitch compatibility between these connectors?

A: Both connectors operate at 0.050" (1.27mm) pitch with 0.100" (2.54mm) row spacing, ensuring mechanical and electrical compatibility in mating applications.
