FOLC-150-L4-L-Q Equivalent & Substitute Parts

Part Overview

The FOLC-150-L4-L-Q is a 200 position receptacle connector from Samtec Inc.'s FOURRAY™ FOLC series, designed for board-to-board applications. This through-hole mounted connector features 0.050" (1.27mm) pitch mating with gold-plated contacts and is actively produced. Substitute parts are identified to support inventory management, procurement flexibility, and design continuity when the primary part number becomes unavailable or when alternative configurations better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FOLC-150-L4-L-Q are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameter is the FOURRAY™ FOLC series base product number (FOLC-150), which ensures identical contact geometry, pitch specifications, and mating interface characteristics.

Substitution is valid when the following parameters remain constant:

• Number of Positions: 200
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 4
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Through Hole
• Contact Finish - Mating: Gold
• Contact Finish Thickness - Mating: 10.0µin (0.25µm)
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Material: Beryllium Copper
• Operating Temperature: -55°C ~ 125°C
• Current Rating: 2.6A per Contact
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Variations in fastening features (such as board lock mechanisms) do not affect electrical or mechanical substitution compatibility when all core parameters remain aligned.

Parameter Comparison

Engineering Selection Recommendations

Both the FOLC-150-L4-L-Q and FOLC-150-04-L-Q-LC are active products from Samtec Inc. and are fully ROHS3 compliant. Selection between these parts should be based on application-specific requirements for fastening features.

The FOLC-150-L4-L-Q provides standard push-pull fastening without additional board lock functionality. The FOLC-150-04-L-Q-LC includes a board lock feature, which provides enhanced mechanical retention in applications requiring vibration resistance or high-reliability interconnection.

Both parts meet identical electrical specifications, thermal ratings, and contact performance requirements. The choice between them depends solely on whether the board lock feature is required for the specific application. Current inventory levels are 953 pcs for FOLC-150-L4-L-Q and 736 pcs for FOLC-150-04-L-Q-LC.

Frequently Asked Questions (FAQ)

Q: Are FOLC-150-L4-L-Q and FOLC-150-04-L-Q-LC electrically interchangeable?

A: Yes. Both parts share identical electrical specifications, including 200 positions, 0.050" (1.27mm) pitch, 2.6A per contact current rating, and gold-plated mating contacts with 10.0µin (0.25µm) thickness.

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

A: The primary difference is the fastening feature. FOLC-150-04-L-Q-LC includes a board lock mechanism for enhanced mechanical retention, while FOLC-150-L4-L-Q uses standard push-pull fastening. All other electrical and mechanical parameters are identical.

Q: Can I use FOLC-150-04-L-Q-LC as a direct replacement for FOLC-150-L4-L-Q?

A: Direct mechanical substitution is valid when the board lock feature does not interfere with the mating connector or PCB layout. Verify that the mating connector and board design accommodate the board lock configuration before substitution.

Q: Do both parts have the same operating temperature range?

A: Yes. Both parts operate across -55°C to 125°C and are rated for identical thermal performance.

Q: Are both parts RoHS compliant?

A: Yes. Both FOLC-150-L4-L-Q and FOLC-150-04-L-Q-LC are ROHS3 compliant and meet the same environmental standards.

Q: What is the through-hole mounting configuration for these connectors?

A: Both parts are designed for through-hole PCB mounting with solder termination. The 200 positions are arranged in 4 rows with 0.050" (1.27mm) row spacing and 0.050" (1.27mm) pitch mating.
