Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TMM-103-01-L-S-RE are identified within the TMM series based on the following critical parameters that determine functional equivalence:

Matching Parameters (Required for Substitution):

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 3
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Current Rating: 3.2A per Contact
• Operating Temperature: -55°C ~ 125°C
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• RoHS Status: ROHS3 Compliant

The identified substitutes (TMM-103-01-L-S-RA and TMM-103-01-LM-S-RA) maintain all critical electrical and mechanical parameters, ensuring direct functional replacement in circuit applications. Variations in part number nomenclature reflect minor design differences that do not affect core connector functionality.

Parameter Comparison

Engineering Selection Recommendations

All three parts (TMM-103-01-L-S-RE, TMM-103-01-L-S-RA, and TMM-103-01-LM-S-RA) maintain active product status and ROHS3 compliance, confirming their suitability for current applications. The electrical and mechanical specifications are identical across all three variants, including current rating, operating temperature range, contact materials, and termination methods. Selection between these parts should be based on availability and inventory levels, as all three are functionally equivalent for board-to-board or cable connector applications requiring 3-position, 2.00mm pitch headers with solder termination.

Frequently Asked Questions (FAQ)

Q: Can TMM-103-01-L-S-RA be used as a direct replacement for TMM-103-01-L-S-RE?

A: Yes. Both parts share identical electrical and mechanical specifications, including 3-position configuration, 0.079" (2.00mm) pitch, 3.2A current rating per contact, and -55°C to 125°C operating temperature range. The parts are functionally equivalent for through-hole, right-angle solder termination applications.

Q: What is the difference between TMM-103-01-L-S-RE and TMM-103-01-LM-S-RA?

A: Both parts maintain identical connector specifications, pitch, position count, current rating, and operating temperature. The part number variation reflects design nomenclature differences within the TMM series but does not affect functional compatibility or electrical performance.

Q: Are all three parts ROHS3 compliant?

A: Yes. TMM-103-01-L-S-RE, TMM-103-01-L-S-RA, and TMM-103-01-LM-S-RA are all ROHS3 compliant, meeting environmental and regulatory requirements for lead-free solder applications.

Q: What is the moisture sensitivity level for these connectors?

A: TMM-103-01-L-S-RE and TMM-103-01-L-S-RA are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. TMM-103-01-LM-S-RA is rated as Not Applicable for moisture sensitivity level.

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

A: Yes. All three parts are rated for operating temperatures from -55°C to 125°C, supporting applications requiring extended temperature ranges within this specification.

Q: What contact material is used in these connectors?

A: All three parts use phosphor bronze contact material with gold plating on the mating surface (10.0µin / 0.25µm thickness) and tin plating on the post surface, ensuring reliable electrical contact and corrosion resistance.
