TMM-120-03-F-D Equivalent & Substitute Parts

Part Overview

The TMM-120-03-F-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This vertical-mount header features 40 positions arranged in 2 rows with 2.00mm pitch spacing. The connector is actively produced and stocked, with 1124 units available in inventory. Alternative equivalent parts may be required due to supply constraints, packaging preferences, or specific application requirements where substitute connectors meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMM-120-03-F-D is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Header, Male Pin)
• Position count and row arrangement (40 positions, 2 rows)
• Mating pitch and row spacing (0.079" / 2.00mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish specifications (Gold mating surface, Tin post)

The two substitute parts listed—Molex 0877584016 and Amphenol ICC 10075024-G01-20ULF—satisfy all core electrical and mechanical parameters required for direct substitution. Both maintain identical position counts, pitch spacing, mounting configuration, and contact finish specifications. Variations in insulation material composition, contact finish thickness, and packaging format do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

All three connectors maintain active product status and comply with RoHS regulations. The TMM-120-03-F-D (Samtec) and 0877584016 (Molex) both achieve ROHS3 compliance, while the 10075024-G01-20ULF (Amphenol ICC) meets RoHS compliance standards. All parts carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions.

Selection between these equivalent parts should be based on:

• Packaging format requirements (Bulk, Tray, or Tube)
• Inventory availability and lead time considerations
• Insulation material compatibility with specific application environments
• Supplier qualification and procurement preferences
• Contact finish thickness specifications where precision is required

The Molex 0877584016 offers the highest inventory availability at 14,084 units. The Amphenol ICC 10075024-G01-20ULF provides the lowest inventory level at 732 units. All three parts satisfy identical electrical and mechanical interface requirements for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0877584016 be used as a direct replacement for the Samtec TMM-120-03-F-D?

A: Yes. Both connectors share identical position counts (40), row configuration (2 rows), mating pitch (2.00mm), mounting type (Through Hole), termination method (Solder), and contact finish specifications (Gold mating, Tin post). The Molex part includes breakaway functionality, which does not affect compatibility with standard mating connectors.

Q: What is the difference in contact finish thickness between these parts?

A: The Samtec TMM-120-03-F-D specifies 3.00µin (0.076µm) gold thickness on mating contacts. The Molex 0877584016 provides 15.0µin (0.38µm), and the Amphenol ICC 10075024-G01-20ULF provides 30.0µin (0.76µm). All thicknesses remain within acceptable ranges for standard connector applications.

Q: Are there differences in insulation material between these connectors?

A: Yes. The Samtec part uses Liquid Crystal Polymer (LCP), the Molex part uses Polyamide (PA46) with glass filling, and the Amphenol ICC part uses Thermoplastic material. All three materials are suitable for the specified operating temperature range and provide equivalent electrical insulation properties.

Q: Which part should be selected for high-volume production?

A: The Molex 0877584016 offers the highest inventory availability (14,084 units) and is packaged in Tray format, which is standard for production environments. The Samtec TMM-120-03-F-D is available in Bulk packaging (1,124 units), and the Amphenol ICC part is supplied in Tube packaging (732 units).

Q: Do all three connectors meet the same compliance standards?

A: All three parts are RoHS compliant. The Samtec and Molex parts achieve ROHS3 compliance specifically. All three carry MSL 1 rating and ECCN EAR99 classification. The Amphenol ICC part is REACH Affected, while the Samtec and Molex parts are REACH Unaffected.

Q: What is the current rating difference between these connectors?

A: The Samtec TMM-120-03-F-D is rated at 3.2A per contact. The Molex 0877584016 does not specify a current rating in the provided data. The Amphenol ICC 10075024-G01-20ULF is rated at 2A (AC/DC) per contact.
