Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSW-103-08-G-D-240 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, 6 positions arranged in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
• Mounting & Termination: Through-hole mounting with solder termination
• Fastening Mechanism: Push-pull fastening type
• Contact Material & Finish: Gold-plated mating surface on phosphor bronze or copper alloy base material
• Electrical Performance: Current rating and operating temperature range
• Compliance: RoHS and flammability certifications

The substitute part 929665-02-03-I (3M) meets these core substitution criteria with documented equivalence in connector topology, pitch, mounting method, and contact configuration. Variations in contact length, current rating, and operating temperature range are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both the MTSW-103-08-G-D-240 and 929665-02-03-I are active production parts with equivalent connector topology, pitch, and mounting specifications. Both parts carry UL94 V-0 flammability certification and RoHS compliance status, meeting standard regulatory requirements for industrial and consumer applications.

The primary differences are:

• Current Rating: The Samtec part supports 3A, while the 3M substitute supports 2.5A. Selection depends on circuit current requirements.
• Operating Temperature Range: The Samtec part operates from -55°C to 125°C; the 3M part operates from -40°C to 105°C. Temperature-critical applications must verify compatibility with the narrower 3M range.
• Contact Dimensions: Minor variations in mating and post contact lengths exist (0.005" difference in mating length, 0.020" difference in post length). These differences are within typical manufacturing tolerances for this connector class and do not affect mechanical or electrical compatibility in standard board-to-board applications.

Selection between these parts should be based on specific application requirements for current capacity and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 929665-02-03-I substitute for the MTSW-103-08-G-D-240 in all applications?

A: The 929665-02-03-I is mechanically and electrically compatible for applications operating within its specified current rating (2.5A maximum) and temperature range (-40°C to 105°C). Applications requiring the full 3A rating or extended temperature operation (-55°C minimum) must use the Samtec part.

Q: What are the key compatibility factors for these connectors?

A: Compatibility is determined by matching pitch (0.100" / 2.54mm), number of positions (6), row configuration (2 rows), mounting type (through-hole), termination method (solder), and fastening mechanism (push-pull). Both parts meet these criteria.

Q: Are there differences in contact dimensions that affect PCB design?

A: Contact length variations between the two parts are minor (0.005" in mating length, 0.020" in post length). These fall within standard manufacturing tolerances for this connector class and do not require PCB redesign for typical board-to-board applications.

Q: Do both parts meet the same compliance standards?

A: Both parts are UL94 V-0 rated and RoHS compliant. The Samtec part carries ROHS3 certification, while the 3M part carries standard RoHS certification. Both meet regulatory requirements for their respective application domains.

Q: What should I verify before switching from MTSW-103-08-G-D-240 to 929665-02-03-I?

A: Verify that your application current requirement does not exceed 2.5A and that your operating temperature range falls within -40°C to 105°C. Confirm PCB layout compatibility with the minor contact dimension variations documented in the parameter comparison table.
