Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FLE-120-01-G-DV-A-TR is determined by the following critical parameters:

• Connector Type: Receptacle
• Number of Positions: 40
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Shape: Square

The substitute part 5-147384-4 (TE Connectivity AMP Connectors) meets these core electrical and mechanical parameters, enabling functional interchangeability in applications requiring a 40-position, 0.050" pitch surface mount receptacle connector with gold mating contacts and push-pull fastening.

Parameter Comparison

Engineering Selection Recommendations

Both the FLE-120-01-G-DV-A-TR and 5-147384-4 are active products with ROHS3 compliance and MSL 1 rating. Selection between these parts should account for the following differences:

The FLE-120-01-G-DV-A-TR supports a higher current rating of 2A per contact compared to the 5-147384-4 at 0.5A per contact. The FLE-120-01-G-DV-A-TR operates across a wider temperature range (-55°C to 125°C) versus the 5-147384-4 (-65°C to 105°C). The 5-147384-4 features a thicker gold mating contact finish (30.0µin versus 10.0µin) and includes board lock and pick-and-place features. Insulation height differs by 0.015" (0.38mm), with the 5-147384-4 being taller.

Frequently Asked Questions (FAQ)

Q: Can the 5-147384-4 directly replace the FLE-120-01-G-DV-A-TR in all applications?

A: Both connectors share identical pitch, row configuration, mounting type, and fastening mechanism. However, the 5-147384-4 has a lower current rating (0.5A per contact versus 2A per contact). Applications requiring the full 2A per contact capacity must use the FLE-120-01-G-DV-A-TR.

Q: What are the packaging differences between these parts?

A: The FLE-120-01-G-DV-A-TR is supplied in Tape & Reel (TR) packaging, while the 5-147384-4 is supplied in Cut Tape (CT) packaging. This affects handling and automated assembly processes.

Q: Are there mechanical compatibility concerns with the different insulation heights?

A: The insulation height difference of 0.015" (0.38mm) may affect mated stacking heights and board clearance. The 5-147384-4 specifies mated stacking heights of 6.35mm, 8.13mm, and 9.91mm. Design verification is necessary when switching between these parts in space-constrained applications.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant with MSL 1 rating. The 5-147384-4 additionally carries a UL94 V-0 material flammability rating and specifies a 30VAC voltage rating, which are not provided for the FLE-120-01-G-DV-A-TR.

Q: What is the difference in contact material composition?

A: The FLE-120-01-G-DV-A-TR uses phosphor bronze contacts, while the 5-147384-4 uses copper alloy contacts. Both are gold-plated at the mating surface.
