Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TFM-110-32-SM-D-LC are qualified based on the following criteria:

Matching Parameters (Non-Negotiable):

• Manufacturer: Samtec Inc.
• Series: Tiger Eye™ TFM
• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 20
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold

Variable Parameter (Substitution Basis):

• Insulation Height: Varies between 0.290" (7.37mm), 0.360" (9.14mm), and 0.435" (11.05mm)

The insulation height variation accommodates different PCB stack-up configurations and mechanical clearance requirements. All substitute parts maintain identical electrical performance, contact configuration, and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and full ROHS3 compliance with UL94 V-0 flammability rating. Selection between TFM-110-32-SM-D-LC, TFM-110-12-S-D-LC, TFM-110-22-S-D-LC, and TFM-110-32-S-D-LC is determined by PCB stack-up height requirements and mechanical clearance constraints.

TFM-110-12-S-D-LC provides the minimum insulation height of 0.290" (7.37mm) for compact designs with limited vertical space. TFM-110-22-S-D-LC offers intermediate height of 0.360" (9.14mm) for standard applications. TFM-110-32-SM-D-LC and TFM-110-32-S-D-LC both provide maximum insulation height of 0.435" (11.05mm) for applications requiring greater clearance above the PCB surface.

All parts share identical electrical ratings, contact configuration, and environmental specifications. Inventory availability ranges from 901 to 1307 units across all variants.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between TFM-110-32-SM-D-LC and its substitutes?

A: The primary difference is insulation height. TFM-110-32-SM-D-LC and TFM-110-32-S-D-LC both feature 0.435" (11.05mm) insulation height, while TFM-110-22-S-D-LC has 0.360" (9.14mm) and TFM-110-12-S-D-LC has 0.290" (7.37mm). All other electrical and mechanical parameters are identical.

Q: Can these parts be used interchangeably in the same application?

A: Interchangeability depends on PCB stack-up design and mechanical clearance requirements. Parts with different insulation heights occupy different vertical space on the board. Verify that the selected part's insulation height accommodates your specific PCB configuration and mating connector clearance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—TFM-110-32-SM-D-LC, TFM-110-12-S-D-LC, TFM-110-22-S-D-LC, and TFM-110-32-S-D-LC—are ROHS3 compliant with UL94 V-0 flammability rating.

Q: What is the current and voltage rating for these connectors?

A: All parts are rated for 2.9A per contact and 275VAC maximum voltage. Operating temperature range is -55°C to 125°C across all variants.

Q: How do I determine which insulation height is correct for my design?

A: Insulation height is determined by your PCB stack-up requirements and the clearance needed between the connector body and adjacent components or the mating connector. Measure the available vertical space on your PCB and select the part with the appropriate insulation height.

Q: Are these parts available in different packaging options?

A: All substitute parts are supplied in Tube packaging. Inventory availability varies: TFM-110-12-S-D-LC (1307 pcs), TFM-110-22-S-D-LC (1017 pcs), TFM-110-32-SM-D-LC (901 pcs), and TFM-110-32-S-D-LC (930 pcs).
