TFM-115-03-L-D Equivalent & Substitute Parts

Part Overview

The TFM-115-03-L-D is a rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFM series. This through-hole connector features 30 positions arranged in 2 rows with 0.050" (1.27mm) pitch, designed for board-to-board or cable applications. The connector is actively produced and stocked, with 682 units available in inventory. Alternative part numbers within this series may be required due to inventory availability, specific application requirements, or design revisions that necessitate components with enhanced features such as solder retention.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-115-03-L-D is determined by strict equivalence across the following critical parameters:

• Manufacturer: Samtec Inc.
• Series: Tiger Eye™ TFM
• Number of Positions: 30
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant

The substitute part TFM-115-03-L-D-WT meets all these criteria and is therefore electrically and mechanically interchangeable. The primary distinction is the addition of solder retention features in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both TFM-115-03-L-D and TFM-115-03-L-D-WT are active products manufactured by Samtec Inc. and maintain full ROHS3 compliance. The electrical and mechanical specifications are identical across all critical parameters including contact rating, voltage rating, operating temperature range, and connector geometry.

The TFM-115-03-L-D-WT variant includes solder retention features, which provide enhanced mechanical stability during PCB assembly processes. Selection between these parts should be based on assembly process requirements and inventory availability. The TFM-115-03-L-D-WT maintains significantly higher stock levels (3319 units versus 682 units), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Are TFM-115-03-L-D and TFM-115-03-L-D-WT electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 2.9A per contact current rating, 275VAC voltage rating, and gold-plated mating contacts with tin-plated posts.

Q: What is the functional difference between these two part numbers?

A: The TFM-115-03-L-D-WT includes solder retention features. This is a mechanical enhancement that does not affect electrical performance but improves component stability during soldering operations.
