Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSW-105-08-G-D-240 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, unshrouded
• Position Count & Row Configuration: 10 positions arranged in 2 rows
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Contact Material & Finish: Gold-plated contacts with phosphor bronze or copper alloy base material
• Insulation Material: Polyester or PBT with glass filling, UL94 V-0 rated
• Fastening Type: Push-Pull mechanism
• Electrical Performance: Current rating and operating temperature range within acceptable tolerance

The identified substitute part 929665-02-05-I (3M) meets these core substitution criteria. Variations in contact length dimensions, current rating tolerance, and operating temperature range represent acceptable engineering trade-offs within the connector category.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (MTSW-105-08-G-D-240): Select this Samtec connector for applications requiring the full operating temperature range of -55°C to 125°C and the 3A current rating. This part is actively produced with robust inventory availability (1034 units in stock) and carries ROHS3 compliance certification.

Substitute Part (929665-02-05-I): The 3M equivalent is suitable for applications operating within -40°C to 105°C and tolerating a 2.5A current rating. This substitute maintains identical pitch, position count, row configuration, and contact finish specifications. Both parts carry UL94 V-0 flammability certification and are RoHS compliant. The 3M part is also actively produced with comparable inventory (1065 units in stock).

Selection between these parts depends on application-specific thermal and current requirements. Both parts are suitable for board-to-board or cable interconnect applications with through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: What determines if 929665-02-05-I can substitute for MTSW-105-08-G-D-240?

A: Substitution is valid when the application operates within the 3M part's temperature range (-40°C to 105°C) and current requirements (2.5A maximum). Both connectors share identical pitch (0.100"), position count (10), row configuration (2 rows), contact type (male pin), mounting method (through-hole), and termination (solder). Contact finish and flammability ratings are equivalent.

Q: Are there dimensional compatibility concerns between these parts?

A: Contact length dimensions differ slightly. The MTSW-105-08-G-D-240 has a mating contact length of 0.240" (6.10mm) versus 0.235" (5.97mm) for the 929665-02-05-I. Post lengths also vary: 0.190" (4.83mm) versus 0.210" (5.33mm). These differences may affect PCB layout and mating depth. Verify board design accommodates the substitute part's dimensional specifications before implementation.

Q: Do both parts meet regulatory compliance requirements?

A: Both connectors carry UL94 V-0 material flammability certification and are RoHS compliant. The MTSW-105-08-G-D-240 is ROHS3 compliant, while the 929665-02-05-I is RoHS compliant. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040. Verify compliance requirements for your specific application and region.

Q: What is the current rating difference, and does it matter?

A: The MTSW-105-08-G-D-240 is rated for 3A, while the 929665-02-05-I is rated for 2.5A. If your application requires continuous current above 2.5A, the Samtec part is required. For applications at or below 2.5A, the 3M substitute is acceptable.

Q: Can these connectors be used interchangeably in existing designs?

A: Mechanical and electrical interchangeability is confirmed for pitch, position count, contact type, and termination method. However, verify contact length dimensions against your PCB layout and mating connector specifications. Thermal and current operating ranges must align with application requirements before substitution.
