Key Parameters

Substitute Part Grouping Explanation

The TSM-102-01-T-DH-P-TR from Samtec Inc. qualifies as a functional substitute based on the following critical parameters:

• Identical mating pitch of 0.100" (2.54mm)
• Matching 4-position, 2-row configuration
• Identical row spacing of 0.100" (2.54mm)
• Surface mount, right-angle mounting orientation
• Solder termination method
• Unshrouded design
• Push-pull fastening type
• UL94 V-0 flammability rating
• MSL 1 (Unlimited) moisture sensitivity level
• Operating temperature range of -55°C ~ 105°C (encompasses the original -40°C ~ 105°C range)

The substitute part maintains mechanical and electrical compatibility through these aligned parameters, enabling direct functional replacement in applications requiring the M20-8910205R.

Parameter Comparison

Engineering Selection Recommendations

The TSM-102-01-T-DH-P-TR is the recommended substitute for the obsolete M20-8910205R. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts maintain UL94 V-0 flammability compliance and REACH unaffected status, meeting regulatory requirements for equivalent applications.

The substitute part extends the lower operating temperature limit to -55°C, providing enhanced thermal performance compared to the original -40°C minimum. Contact finish differences (tin versus gold flash) and insulation material variations (LCP versus polyamide) do not compromise functional compatibility for standard board-to-board or cable connection applications within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can the TSM-102-01-T-DH-P-TR directly replace the M20-8910205R in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (4), row configuration (2), mounting orientation (surface mount right-angle), and termination method (solder). Mechanical and electrical compatibility is maintained across these critical parameters.

Q: What are the differences in contact finish between these parts?

A: The M20-8910205R uses gold flash plating on brass contacts, while the TSM-102-01-T-DH-P-TR uses tin plating on phosphor bronze contacts. Both finishes provide adequate corrosion resistance and electrical conductivity for standard applications. Contact finish selection does not affect mating compatibility.

Q: Does the insulation material change affect performance?

A: The M20-8910205R uses polyamide (PA6T) insulation, while the TSM-102-01-T-DH-P-TR uses liquid crystal polymer (LCP). Both materials achieve UL94 V-0 flammability ratings and maintain MSL 1 moisture sensitivity levels. Material selection reflects manufacturing differences but does not impact functional performance in equivalent applications.

Q: Why is the operating temperature range different?

A: The TSM-102-01-T-DH-P-TR extends the lower temperature limit to -55°C compared to the M20-8910205R at -40°C. This represents an enhancement in thermal capability. Both parts support the upper limit of 105°C, ensuring compatibility across the original operating range.

Q: What packaging format is available for the substitute part?

A: The TSM-102-01-T-DH-P-TR is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. This packaging format is standard for high-volume production environments.

Q: Are there any compliance or regulatory differences?

A: Both parts maintain identical REACH unaffected status and EAR99 ECCN classification. No regulatory barriers exist to substitution. The TSM-102-01-T-DH-P-TR includes RoHS3 compliance certification, providing additional environmental compliance documentation.
