Key Parameters

Substitute Part Grouping Explanation

Substitution within the TMM series is determined by the following critical parameters that must remain constant:

• Base product number (TMM-103)
• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (3)
• Number of rows (1)
• Pitch - mating (0.079" / 2.00mm)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact material (Phosphor Bronze)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Current rating (3.2A per Contact)

The primary variable distinguishing the main part from its substitute is the mounting type: the TMM-103-04-G-S-SM is configured for surface mount, while the substitute TMM-103-01-G-S is configured for through-hole mounting. This difference affects the contact length specifications and overall connector geometry but does not alter the electrical performance or mating interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the TMM-103-04-G-S-SM and TMM-103-01-G-S are active products from Samtec Inc. and maintain full ROHS3 compliance. Selection between these parts is determined by the printed circuit board assembly method:

The TMM-103-04-G-S-SM is specified for surface mount assembly and is appropriate for applications utilizing automated pick-and-place equipment and reflow soldering processes.

The TMM-103-01-G-S is specified for through-hole assembly and is appropriate for applications utilizing wave soldering or manual insertion processes.

Both parts share identical electrical characteristics, mating pitch, contact material composition, and operating temperature specifications. The contact geometry differences reflect the distinct mounting methodologies and do not affect mating interface compatibility with corresponding receptacle connectors within the TMM series.

Frequently Asked Questions (FAQ)

Q: Can TMM-103-01-G-S be used as a direct replacement for TMM-103-04-G-S-SM?

A: Substitution is possible only if the printed circuit board design accommodates through-hole mounting instead of surface mount. The mating interface and electrical performance are equivalent, but the physical mounting footprint and termination method differ.

Q: What is the primary difference between these two parts?

A: The mounting type distinguishes these parts. TMM-103-04-G-S-SM uses surface mount termination suitable for reflow soldering, while TMM-103-01-G-S uses through-hole termination suitable for wave soldering or manual insertion.

Q: Are the contact specifications identical between these parts?

A: The mating contact specifications are equivalent. Both parts feature 0.079" (2.00mm) pitch, square contacts with gold finish, and 3.2A current rating per contact. The post contact length differs due to the distinct mounting configurations.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity level. The TMM-103-04-G-S-SM carries a UL94 V-0 flammability rating; the flammability rating for TMM-103-01-G-S is not specified in available documentation.

Q: What is the packaging difference?

A: TMM-103-04-G-S-SM is supplied in tube packaging, while TMM-103-01-G-S is supplied in bulk packaging. This affects order quantities and handling but does not impact electrical or mechanical performance.
