Engineering Selection Recommendations

Both the MTSW-110-07-G-S-205 and 961110-6404-AR are active production parts with UL94 V-0 flammability compliance and RoHS certification. The primary differences between these parts are:

Operating temperature range: The MTSW-110-07-G-S-205 operates from -55°C to 125°C, while the 961110-6404-AR operates from -25°C to 105°C. Applications requiring extended low-temperature operation below -25°C or high-temperature operation above 105°C must use the Samtec part.

Current rating: The MTSW-110-07-G-S-205 is rated for 3A per contact, while the 961110-6404-AR is rated for 2A per contact. Applications requiring current capacity above 2A per contact must use the Samtec part.

Contact finish post: The MTSW-110-07-G-S-205 uses gold plating on the post, while the 961110-6404-AR uses tin. This difference may affect solderability characteristics and long-term reliability in specific environmental conditions.

Insulation material: The MTSW-110-07-G-S-205 uses polyester glass-filled material, while the 961110-6404-AR uses thermoplastic. Material selection may impact mechanical properties and environmental resistance.

The 961110-6404-AR is suitable for applications operating within -25°C to 105°C with current requirements not exceeding 2A per contact.

Frequently Asked Questions (FAQ)

Q: Can the 961110-6404-AR directly replace the MTSW-110-07-G-S-205 in all applications?

A: No. The 961110-6404-AR has a lower current rating (2A vs. 3A) and narrower operating temperature range (-25°C to 105°C vs. -55°C to 125°C). Substitution is valid only when application requirements fall within these limits.

Q: What are the mechanical compatibility considerations?

A: Both parts share identical pitch (0.100" / 2.54mm), position count (10), and row configuration (1 row). Minor dimensional variations exist in contact length and insulation height, but these do not prevent mechanical mating with standard 2.54mm pitch receptacles.

Q: Are there differences in solder joint reliability between these parts?

A: The MTSW-110-07-G-S-205 uses gold-plated posts, while the 961110-6404-AR uses tin-plated posts. Both are solderable; however, gold plating may provide different long-term reliability characteristics in specific environmental or thermal cycling conditions.

Q: Do both parts meet the same compliance standards?

A: Both parts are UL94 V-0 rated and RoHS compliant. The MTSW-110-07-G-S-205 is ROHS3 compliant, while the 961110-6404-AR is RoHS compliant. Both meet flammability and hazardous substance restrictions for standard applications.

Q: What is the inventory status for these parts?

A: The MTSW-110-07-G-S-205 has 1000 pieces in stock. The 961110-6404-AR has 1319 pieces in stock.
