TFC-120-12-L-D-A Equivalent & Substitute Parts

Part Overview

The TFC-120-12-L-D-A is a Samtec Tiger Eye™ TFC series rectangular connector header designed for surface mount board-to-board applications. This shrouded 40-position header features 0.050" (1.27mm) pitch contacts with gold-plated mating surfaces and tin-plated posts. The connector is actively produced and maintains full RoHS3 compliance with UL94 V-0 flammability rating, making it suitable for industrial and commercial electronic assemblies requiring reliable push-pull mated connections.

Substitute parts are identified when design requirements permit variation in specific mechanical or electrical parameters while maintaining core functional compatibility within the Tiger Eye™ TFC series.

Key Parameters

Substitute Part Grouping Explanation

The TFC-120-32-L-D-A qualifies as a direct substitute based on the following criteria:

Matching Parameters (Substitution Basis):

• Identical manufacturer (Samtec Inc.)
• Identical series (Tiger Eye™ TFC)
• Identical connector type (Header, Male Pin)
• Identical pitch specifications (0.050" mating pitch, 0.050" row spacing)
• Identical position count (40 positions, 2 rows)
• Identical mounting method (Surface Mount)
• Identical fastening type (Push-Pull)
• Identical electrical ratings (3.1A per contact, 275VAC)
• Identical operating temperature range (-55°C ~ 125°C)
• Identical compliance certifications (ROHS3, UL94 V-0)
• Identical contact materials and finishes (Phosphor Bronze, Gold mating/Tin post)

Variable Parameter:

• Insulation Height: TFC-120-12-L-D-A = 0.296" (7.52mm); TFC-120-32-L-D-A = 0.441" (11.20mm)

The insulation height difference reflects design variations within the same product family and does not affect electrical or functional compatibility when mating with compatible receptacles designed for the TFC series.

Parameter Comparison

Engineering Selection Recommendations

Both TFC-120-12-L-D-A and TFC-120-32-L-D-A are active products with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts depends on PCB layout constraints and available board space for the connector footprint.

The TFC-120-12-L-D-A features a lower insulation height of 0.296" (7.52mm), suitable for applications with space-constrained vertical clearance. The TFC-120-32-L-D-A provides an insulation height of 0.441" (11.20mm), accommodating designs requiring greater standoff distance from the PCB surface.

Both parts maintain identical electrical performance, contact ratings, and environmental specifications. Inventory availability shows TFC-120-32-L-D-A at 1110 pieces and TFC-120-12-L-D-A at 948 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can TFC-120-32-L-D-A replace TFC-120-12-L-D-A in existing designs?

A: Yes, provided the increased insulation height of 0.441" (11.20mm) versus 0.296" (7.52mm) does not conflict with PCB layout or enclosure constraints. All electrical and functional parameters remain identical.

Q: Are the mating interfaces compatible between these two part numbers?

A: Yes. Both headers feature identical 0.050" (1.27mm) pitch, 40-position configuration, and male pin contact geometry. They mate with the same TFC series receptacles.

Q: What is the significance of the insulation height difference?

A: Insulation height determines the vertical distance from the PCB surface to the contact mating plane. The TFC-120-12-L-D-A provides a lower profile suitable for compact assemblies, while the TFC-120-32-L-D-A offers greater standoff for applications requiring additional clearance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TFC-120-12-L-D-A and TFC-120-32-L-D-A are ROHS3 compliant, UL94 V-0 rated, and carry identical electrical certifications (275VAC, 3.1A per contact).

Q: Are there any differences in contact material or finish?

A: No. Both parts use phosphor bronze contacts with gold-plated mating surfaces (10.0µin thickness) and tin-plated posts.

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.
