Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMM-126-01-T-S-RE is determined by the following critical parameters:

• Connector series (TMM)
• Number of positions (26)
• Pitch specification (0.079" / 2.00mm)
• Contact type (Male Pin)
• Mounting configuration (Through Hole, Right Angle)
• Current rating (3.2A per Contact)
• Operating temperature range (-55°C ~ 105°C)
• Termination method (Solder)
• Insulation material (Liquid Crystal Polymer)

The TMM-126-01-T-S-RA qualifies as a direct substitute based on identical values across all critical parameters. Both parts share the same base product number (TMM-126) and maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TMM-126-01-T-S-RE and TMM-126-01-T-S-RA are active production parts with full ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on:

• Current inventory availability at your supplier
• Lead time requirements for your production schedule
• Application-specific mounting orientation requirements
• Moisture sensitivity considerations (MSL 1 for RE variant; Not Applicable for RA variant)

Both parts meet identical electrical and mechanical specifications and are suitable for direct substitution in applications requiring 26-position, 2.00mm pitch through-hole header connectors with 3.2A per contact current capacity.

Frequently Asked Questions (FAQ)

Q: Are TMM-126-01-T-S-RE and TMM-126-01-T-S-RA fully interchangeable?

A: Yes. Both parts share identical electrical and mechanical parameters including connector type, position count, pitch, contact ratings, and operating temperature range. They are direct substitutes within the TMM series.

Q: What is the difference between the RE and RA designations?

A: The designations indicate different manufacturing or configuration variants within the same base product number (TMM-126). Both maintain identical functional specifications for connector applications.

Q: Does the moisture sensitivity level difference affect substitution?

A: The MSL rating difference (1 for RE; Not Applicable for RA) reflects storage and handling requirements but does not affect electrical or mechanical compatibility. Selection should account for your storage environment and handling procedures.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -55°C to 105°C, suitable for industrial and automotive applications within this range.

Q: What is the current capacity per contact?

A: Both parts are rated at 3.2A per contact, supporting total current capacity of 83.2A across all 26 positions under standard operating conditions.
