MTSW-105-08-G-S-280 Equivalent & Substitute Parts

Part Overview

The MTSW-105-08-G-S-280 is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 5-position, single-row connector operates at 3A current rating with a 0.100" (2.54mm) pitch and features gold-plated phosphor bronze contacts. The product maintains active status with full RoHS3 compliance and UL94 V-0 flammability rating. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate alternative suppliers.

Key Parameters

Substitute Part Grouping Explanation

The 961105-6804-AR from 3M qualifies as a substitute based on the following critical parameters:

• Connector Configuration: Both parts are 5-position, single-row headers with 0.100" (2.54mm) pitch
• Contact Type: Both feature male pin contacts with square geometry
• Mounting Method: Both are through-hole solder-terminated connectors
• Fastening Type: Both employ push-pull fastening
• Shrouding: Both are unshrouded designs
• Flammability Compliance: Both meet UL94 V-0 rating
• RoHS Compliance: Both are RoHS compliant

Substitution is valid where the application tolerates the parameter variations documented in the Parameter Comparison table.

Parameter Comparison

Engineering Selection Recommendations

Both the MTSW-105-08-G-S-280 and 961105-6804-AR maintain active product status with full RoHS compliance and UL94 V-0 flammability certification, qualifying them for equivalent applications in standard through-hole connector installations.

The MTSW-105-08-G-S-280 is specified for applications requiring the full operating temperature range of -55°C to 125°C and the 3A current rating. The 961105-6804-AR operates within -25°C to 105°C and carries a 2A current rating. Selection between these parts must account for the specific thermal and current requirements of the target application.

Contact geometry and post length differences are minor and do not affect mating compatibility with standard 0.100" (2.54mm) pitch receptacles. The variation in contact finish thickness and post material (gold versus tin) reflects manufacturing process differences between suppliers and does not impact functional equivalence for standard board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Can the 961105-6804-AR directly replace the MTSW-105-08-G-S-280 in all applications?

A: Direct substitution is valid for applications operating within -25°C to 105°C and requiring maximum 2A current. Applications demanding the full -55°C to 125°C temperature range or 3A current rating require the MTSW-105-08-G-S-280.

Q: What are the key differences between these two connector headers?

A: The primary differences are operating temperature range (-55°C to 125°C versus -25°C to 105°C), current rating (3A versus 2A), contact material (phosphor bronze versus copper alloy), and post finish (gold versus tin). Both maintain identical pitch, position count, and mounting configuration.

Q: Are both parts RoHS compliant?

A: Yes. The MTSW-105-08-G-S-280 is ROHS3 compliant, and the 961105-6804-AR is RoHS compliant. Both meet flammability requirements at UL94 V-0.

Q: Does the difference in contact finish thickness affect performance?

A: Contact finish thickness variations (10.0µin versus flash) reflect supplier manufacturing standards. For standard board-to-board applications, these differences do not impact functional performance or reliability.

Q: Can these connectors be used interchangeably with standard 0.100" pitch receptacles?

A: Yes. Both headers feature 0.100" (2.54mm) pitch male pin contacts and are compatible with standard receptacles designed for this pitch specification.
