Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FLE-128-01-G-DV-TR is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Position count (56 positions)
• Mating pitch (0.050" / 1.27mm)
• Row configuration (2 rows at 0.050" spacing)
• Contact type (Female Socket)
• Mounting method (Surface Mount)
• Contact finish (Gold plating)
• Current rating (2A per contact)
• Operating temperature range (-55°C ~ 125°C)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Compliance certifications (ROHS3, MSL 1)

The identified substitute maintains all electrical and mechanical parameters while differing only in packaging configuration and assembly features that do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The FLE-128-01-G-DV-P-TR includes Pick and Place features, which may provide advantages in automated assembly environments. Current inventory levels show 887 units for the primary part and 2614 units for the substitute, allowing flexibility in procurement strategy. Both parts are manufactured by Samtec Inc. under the FLE series and share identical electrical and mechanical specifications, ensuring direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Are FLE-128-01-G-DV-TR and FLE-128-01-G-DV-P-TR electrically interchangeable?

A: Yes. Both parts are electrically identical with matching contact ratings (2A per contact), operating temperature range (-55°C ~ 125°C), and gold-plated contact finishes. They can be used interchangeably in circuit applications without electrical performance differences.

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

A: The primary difference is the inclusion of Pick and Place features in the FLE-128-01-G-DV-P-TR variant. Both parts share identical mechanical dimensions, pitch specifications (0.050"), position count (56), and row configuration (2 rows). The packaging format (Tape & Reel) is identical for both.

Q: Can I substitute FLE-128-01-G-DV-P-TR for FLE-128-01-G-DV-TR in existing designs?

A: Yes. The substitute part maintains all critical parameters including connector type, position count, mating pitch, row spacing, mounting type, contact type, contact finish, current rating, operating temperature, termination method, and fastening mechanism. No design modifications are required.

Q: Are both parts ROHS3 compliant?

A: Yes. Both FLE-128-01-G-DV-TR and FLE-128-01-G-DV-P-TR carry ROHS3 compliance certification with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What does the Pick and Place feature in FLE-128-01-G-DV-P-TR mean?

A: Pick and Place features are design elements that facilitate automated component placement during surface mount assembly processes. This does not affect electrical or mechanical compatibility with mating connectors or circuit board designs.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts share identical insulation height (0.172" / 4.37mm), contact shape (Square), and all mechanical specifications. They occupy the same footprint on circuit boards.
