TFC-110-12-L-D-A-K Equivalent & Substitute Parts

Part Overview

The TFC-110-12-L-D-A-K is a Samtec Tiger Eye™ TFC series rectangular connector header designed for surface mount board-to-board or cable applications. This shrouded 4-wall header features 20 positions arranged in 2 rows with 0.050" (1.27mm) pitch and mating contact length of 0.139" (4.63mm). The connector is actively produced and widely stocked, with 685 units available in inventory. Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

The TFC-110-32-L-D-A-K qualifies as a direct substitute based on the following critical parameters that remain constant:

• Manufacturer: Samtec Inc.
• Series: Tiger Eye™ TFC
• Connector Type: Header with Male Pin contacts
• Number of Positions: 20 in 2 rows
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Contact Type and Finish: Gold-plated mating surface (10.0µin / 0.25µm)
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Current Rating: 3.1A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The primary difference between these parts is the insulation height, which affects board-level spacing but does not alter electrical performance or contact compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both TFC-110-12-L-D-A-K and TFC-110-32-L-D-A-K are active products manufactured by Samtec Inc. and maintain identical electrical specifications, contact configurations, and compliance certifications. Selection between these parts depends on printed circuit board layout requirements.

The TFC-110-12-L-D-A-K features an insulation height of 0.296" (7.52mm), suitable for designs with limited vertical clearance above the connector. The TFC-110-32-L-D-A-K provides an insulation height of 0.441" (11.20mm), accommodating applications requiring greater standoff distance from the PCB surface.

Both connectors are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity classification. Current and voltage ratings remain constant at 3.1A per contact and 275VAC respectively across the full operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can TFC-110-32-L-D-A-K replace TFC-110-12-L-D-A-K in existing designs?

A: Electrical substitution is valid. The primary consideration is insulation height. The TFC-110-32-L-D-A-K is 0.145" (3.68mm) taller. Verify that PCB layout and component clearances accommodate this increased height before substitution.

Q: Are the contact configurations identical between these parts?

A: Yes. Both connectors feature 20 positions in 2 rows with 0.050" (1.27mm) pitch and row spacing. Contact type, material, finish, and mating length are identical.

Q: Do these connectors have different electrical ratings?

A: No. Current rating (3.1A per contact), voltage rating (275VAC), and operating temperature range (-55°C to 125°C) are identical for both parts.

Q: Are both parts RoHS compliant?

A: Yes. Both TFC-110-12-L-D-A-K and TFC-110-32-L-D-A-K are ROHS3 compliant with UL94 V-0 flammability rating.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are these parts actively manufactured?

A: Yes. Both parts maintain active product status with current inventory availability (685 and 718 units respectively).
