Engineering Selection Recommendations

All listed substitute parts maintain functional compatibility with the 68418-402 through matching core specifications: 2-position, 0.100" (2.54mm) pitch, male pin headers with square contacts, unshrouded design, through-hole solder termination, and UL94 V-0 flammability rating.

The Samtec HTSW series (HTSW-102-07-S-S, HTSW-102-08-L-S, HTSW-102-08-S-S, HTSW-102-22-S-S, HTSW-102-23-G-S, HTSW-102-23-L-S, HTSW-102-26-F-S) offers ROHS3 compliance and extended operating temperature range (-55°C to 125°C) compared to the original part. These variants differ primarily in contact post length and contact finish specifications, allowing selection based on specific board depth and environmental requirements.

The Samtec Flex Stack MTLW series (MTLW-102-07-G-S-230, MTLW-102-07-L-S-250) provides reduced insulation height (0.060" versus 0.100") and higher current rating (5.2A per contact), suitable for compact board layouts and higher current applications.

The 3M 929450-01-02-I offers breakaway header functionality with gold-plated copper alloy contacts and specified operating temperature range (-40°C to 105°C), providing an alternative for applications requiring component separation capability.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 68418-402 with any of the listed parts without PCB redesign?

A: Yes, all listed substitute parts share the critical specifications that determine PCB compatibility: 2-position, 0.100" (2.54mm) pitch, male pin headers with square contacts, through-hole solder termination, and unshrouded design. However, variations in contact post length (ranging from 0.100" to 0.400") and insulation height (0.060" to 0.110") may affect board depth requirements. Verify your specific board thickness and mating connector depth before selection.

Q: What is the difference between the HTSW and MTLW series?

A: The HTSW series maintains standard insulation height (0.100") with variable contact post lengths from 0.100" to 0.300". The MTLW Flex Stack series features reduced insulation height (0.060") and higher current rating (5.2A per contact), designed for compact applications. Both series offer ROHS3 compliance and extended temperature range (-55°C to 125°C).

Q: Does the contact finish affect electrical performance?

A: Contact finish (tin or gold) does not affect basic electrical connectivity. Gold-plated contacts (used in most Samtec substitutes) provide enhanced corrosion resistance and lower contact resistance compared to tin plating. The 68418-402 uses tin plating; substitutes with gold plating offer improved reliability in demanding environments.

Q: Are there inventory considerations for substitute selection?

A: Yes. The HTSW-102-08-S-S has the highest inventory (6625 Pcs), followed by HTSW-102-23-G-S (3320 Pcs) and MTLW-102-07-L-S-250 (4856 Pcs). The original 68418-402 has 683 Pcs in stock. Substitute selection may be influenced by availability and supply chain requirements.

Q: What is the significance of RoHS compliance status?

A: The original 68418-402 is RoHS non-compliant. All Samtec substitutes (HTSW and MTLW series) are ROHS3 compliant, meeting current environmental regulations. The 3M 929450-01-02-I RoHS status is not specified. For applications subject to RoHS requirements, Samtec parts are the appropriate choice.

Q: Can I use the 3M 929450-01-02-I as a direct replacement?

A: The 3M part is functionally compatible as a 2-position, 0.100" (2.54mm) pitch header with male pins and UL94 V-0 rating. The breakaway feature provides additional design flexibility. However, it uses copper alloy contacts with gold plating (versus phosphor bronze in the original), operates at a lower maximum temperature (-40°C to 105°C), and has different contact dimensions. Verify compatibility with your specific application requirements.
