Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMM-148-01-T-S-RE is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (48)
• Pitch specification (0.079" / 2.00mm)
• Mounting configuration (Through Hole, Right Angle)
• Termination method (Solder)
• Contact material (Phosphor Bronze)
• Insulation material (Liquid Crystal Polymer)
• Current rating (3.2A per Contact)
• Operating temperature range (-55°C ~ 105°C)
• Compliance certifications (ROHS3, MSL 1)

The identified substitute part TMM-148-01-T-S-RA meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

Both TMM-148-01-T-S-RE and TMM-148-01-T-S-RA are Active status products from Samtec Inc. with identical electrical and mechanical specifications. Both parts are ROHS3 compliant and carry MSL 1 rating, confirming suitability for standard manufacturing and storage conditions without moisture sensitivity constraints. Selection between these parts may be based on inventory availability, lead time, or supply chain preferences, as they are functionally equivalent for all circuit design and assembly applications.

Frequently Asked Questions (FAQ)

Q: Are TMM-148-01-T-S-RE and TMM-148-01-T-S-RA electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 48-position configuration, 2.00mm pitch, 3.2A per contact current rating, and -55°C to 105°C operating temperature range. They are direct electrical equivalents.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts feature identical mechanical specifications: through-hole right-angle mounting, solder termination, phosphor bronze contacts with tin finish, and LCP insulation. They are mechanically interchangeable for board-level assembly.

Q: What is the significance of the part number suffix difference between RE and RA?

A: The suffix designates specific connector variants within the TMM-148 base product family. Both suffixes represent valid product configurations that meet the same electrical and mechanical requirements for 48-position 2.00mm pitch headers.

Q: Are both parts compliant with RoHS regulations?

A: Yes. Both TMM-148-01-T-S-RE and TMM-148-01-T-S-RA are ROHS3 compliant, confirming restriction of hazardous substances in accordance with current environmental standards.

Q: What does MSL 1 rating mean for these connectors?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture sensitivity constraints. These parts do not require special moisture control during storage or handling.

Q: Can I substitute one part for the other in existing designs?

A: Yes. The parts are functionally equivalent across all provided specifications. Design changes are not required for substitution.
