Substitute Part Grouping Explanation

The TFM-110-32-L-D-LC has one identified substitute: TFM-110-22-L-D-LC. Both parts share the same manufacturer (Samtec Inc.), series (Tiger Eye™ TFM), and critical electrical specifications. Substitution is valid based on the following matching parameters:

• Connector type, contact type, and contact material (Male Pin, Phosphor Bronze)
• Number of positions and row configuration (20 positions, 2 rows)
• Pitch specifications (0.050" mating pitch, 0.050" row spacing)
• Mounting type and termination method (Surface Mount, Solder)
• Electrical ratings (2.9A per contact, 275VAC)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (ROHS3, UL94 V-0)
• Contact finish specifications (Gold mating, Tin post)

The primary difference between these parts is the insulation height: TFM-110-32-L-D-LC has 0.435" (11.05mm) while TFM-110-22-L-D-LC has 0.360" (9.14mm). This dimensional variation allows selection based on specific board layout and stacking requirements.

Parameter Comparison

Engineering Selection Recommendations

Both TFM-110-32-L-D-LC and TFM-110-22-L-D-LC are active production parts with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is determined by the insulation height requirement for your specific application:

• Select TFM-110-32-L-D-LC when a taller profile (0.435" / 11.05mm insulation height) is required for board layout or stacking configurations.
• Select TFM-110-22-L-D-LC when a lower profile (0.360" / 9.14mm insulation height) is needed for space-constrained applications.

Both parts maintain identical electrical performance, contact specifications, and environmental ratings. The choice is purely dimensional based on PCB design requirements.

Frequently Asked Questions (FAQ)

Q: Can TFM-110-22-L-D-LC be used as a direct replacement for TFM-110-32-L-D-LC?

A: Yes, provided your PCB layout accommodates the reduced insulation height of 0.360" (9.14mm) versus 0.435" (11.05mm). All electrical, mechanical, and contact specifications are identical.
