Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSW-102-22-G-S-456 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pin contacts for through-hole mounting
• Position Count & Pitch: 2 positions at 0.100" (2.54mm) mating pitch
• Electrical Performance: Current and voltage ratings sufficient for the application
• Termination Method: Solder termination capability
• Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance
• Operating Temperature: Minimum -55°C ~ 105°C range (MTSW-102-22-G-S-456 operates to 125°C)

The substitute part 3-644695-2 (TE Connectivity AMP Connectors, MTA-100 series) meets the core functional requirements of a 2-position, 0.100" pitch header with male pins, through-hole mounting, and solder termination. Both parts maintain UL94 V-0 flammability rating and ROHS3 compliance. Differences in contact finish material, contact geometry, and maximum operating temperature represent design variations within the rectangular connector category that do not preclude substitution in applications operating within the lower temperature envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the MTSW-102-22-G-S-456 and 3-644695-2 are active production parts with ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and consumer applications. Selection between these parts should be based on:

• Temperature Operating Envelope: The MTSW-102-22-G-S-456 supports operation to 125°C, while the 3-644695-2 is rated to 105°C. Applications requiring sustained operation above 105°C require the Samtec part.
• Contact Finish Specification: The MTSW-102-22-G-S-456 features gold plating on mating contacts, providing enhanced corrosion resistance and lower contact resistance. The 3-644695-2 uses tin finish, suitable for general-purpose applications with standard environmental exposure.
• Mechanical Design: The MTSW-102-22-G-S-456 is cuttable, allowing field customization of position count. The 3-644695-2 uses kinked pin termination, providing mechanical retention during assembly.
• Inventory Availability: The 3-644695-2 maintains higher stock levels (11,199 units) compared to the MTSW-102-22-G-S-456 (1,081 units), supporting rapid procurement timelines.

Frequently Asked Questions (FAQ)

Q: Can the 3-644695-2 directly replace the MTSW-102-22-G-S-456 in all applications?

A: Direct replacement is valid for applications operating within -55°C to 105°C. Applications requiring sustained operation above 105°C must use the MTSW-102-22-G-S-456. Both parts share identical pitch (0.100"), position count (2), contact type (male pin), and mounting method (through-hole solder), ensuring mechanical and electrical compatibility within the specified temperature range.

Q: What are the differences in contact finish, and how do they affect performance?

A: The MTSW-102-22-G-S-456 uses gold plating (10.0µin thickness) on mating contacts, providing superior corrosion resistance and lower contact resistance in high-reliability applications. The 3-644695-2 uses tin finish (150.0µin thickness), which is suitable for general-purpose applications with standard environmental exposure. Gold-plated contacts are preferred in applications with frequent mating cycles or harsh environments.

Q: Are both parts RoHS compliant?

A: Yes, both the MTSW-102-22-G-S-456 and 3-644695-2 are ROHS3 compliant, meeting EU Directive 2011/65/EU requirements for restricted hazardous substances.

Q: What is the difference between cuttable and kinked pin termination?

A: The MTSW-102-22-G-S-456 features cuttable design, allowing the connector to be cut to reduce the number of positions in the field. The 3-644695-2 uses kinked pin termination, where the pin is bent to provide mechanical retention during PCB assembly. Both designs support solder termination; the choice depends on whether field customization of position count is required.

Q: Do both parts support the same current rating?

A: The MTSW-102-22-G-S-456 is rated for 3A per contact. The 3-644695-2 current rating varies by wire gauge, as this part is designed for board-to-cable/wire applications. For board-to-board applications, verify the specific wire gauge and corresponding current rating with the manufacturer datasheet.
