Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-110-22-S-D is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 20
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Shrouding: Shrouded - 4 Wall

Secondary Compatibility Criteria:

• Insulation Height: 0.360" (9.14mm)
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0

Substitute parts within the Tiger Eye™ TFM series maintain identical primary parameters. Variations in insulation height, features (Board Guide, Board Lock, Pick and Place), and contact length specifications define distinct part variants. The TE Connectivity 5-104693-2 represents a cross-manufacturer alternative with compatible pitch, position count, and row configuration, though with differences in contact shape, current rating, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Samtec Tiger Eye™ TFM Series Substitutes (Direct Compatibility):

TFM-110-22-S-D-A and TFM-110-22-S-D-LC are direct functional equivalents with identical insulation height (0.360" / 9.14mm), current rating (2.9A per Contact), and voltage rating (275VAC). Both variants are ROHS3 compliant and maintain the same operating temperature range (-55°C ~ 125°C). Selection between these variants depends on mechanical feature requirements: TFM-110-22-S-D-A includes Board Guide feature, while TFM-110-22-S-D-LC includes Board Lock feature. Both are active products with higher inventory availability than the base TFM-110-22-S-D.

Samtec Tiger Eye™ TFM Series Variants (Insulation Height Differences):

TFM-110-12-S-D-A and TFM-110-12-S-D-LC feature reduced insulation height (0.290" / 7.37mm) compared to the main part. These variants maintain all electrical specifications (2.9A per Contact, 275VAC, -55°C ~ 125°C) and are suitable for applications with space constraints. TFM-110-12-S-D-A includes Board Guide feature, while TFM-110-12-S-D-LC includes Board Lock feature. Inventory for these variants is higher (2060 Pcs and 1307 Pcs respectively).

TFM-110-32-S-D-A and TFM-110-32-S-D-LC feature increased insulation height (0.435" / 11.05mm) and are suitable for applications requiring greater standoff distance. Electrical specifications remain identical (2.9A per Contact, 275VAC, -55°C ~ 125°C). TFM-110-32-S-D-A includes Board Guide feature, while TFM-110-32-S-D-LC includes Board Lock feature.

Cross-Manufacturer Alternative:

TE Connectivity 5-104693-2 (AMPMODU 50/50 Grid series) shares identical pitch (0.050" / 1.27mm), position count (20), and row configuration (2 rows). However, this part differs in contact shape (Circular vs. Square), current rating (0.5A per Contact vs. 2.9A per Contact), and operating temperature range (-65°C ~ 105°C vs. -55°C ~ 125°C). This alternative is suitable only for applications with lower current requirements and does not support the full thermal range of the TFM-110-22-S-D. All parts maintain ROHS3 compliance and UL94 V-0 flammability rating.

Frequently Asked Questions (FAQ)

Q: Can TFM-110-22-S-D-A be used as a direct replacement for TFM-110-22-S-D?

A: Yes. Both parts share identical pitch (0.050" / 1.27mm), position count (20), row configuration (2 rows), insulation height (0.360" / 9.14mm), current rating (2.9A per Contact), voltage rating (275VAC), and operating temperature range (-55°C ~ 125°C). The primary difference is the addition of a Board Guide feature in the -A variant. Both are ROHS3 compliant and active products.

Q: What is the difference between Board Guide and Board Lock features?

A: Board Guide (present in -A variants) and Board Lock (present in -LC variants) are mechanical features that affect connector alignment and retention during assembly. Both features maintain identical electrical and thermal specifications. Selection depends on the specific mechanical requirements of the application and PCB design.

Q: Can TFM-110-12-S-D-A replace TFM-110-22-S-D?

A: Electrical and thermal specifications are identical (2.9A per Contact, 275VAC, -55°C ~ 125°C). The primary difference is insulation height: TFM-110-12-S-D-A is 0.290" (7.37mm) versus TFM-110-22-S-D at 0.360" (9.14mm). This variant is suitable only if the reduced standoff distance is compatible with the application's PCB layout and mating connector specifications.

Q: Is TE Connectivity 5-104693-2 compatible with TFM-110-22-S-D?

A: Pitch (0.050" / 1.27mm), position count (20), and row configuration (2 rows) are identical. However, current rating differs significantly: 5-104693-2 is rated at 0.5A per Contact versus TFM-110-22-S-D at 2.9A per Contact. Operating temperature range also differs: 5-104693-2 supports -65°C ~ 105°C versus TFM-110-22-S-D at -55°C ~ 125°C. This part is suitable only for low-current applications within its specified temperature range.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including TFM-110-22-S-D-A, TFM-110-22-S-D-LC, TFM-110-12-S-D-A, TFM-110-12-S-D-LC, TFM-110-32-S-D-A, TFM-110-32-S-D-LC, and 5-104693-2, are ROHS3 compliant with UL94 V-0 flammability rating and Moisture Sensitivity Level 1 (Unlimited).

Q: What determines substitution eligibility for this connector?

A: Primary compatibility is determined by pitch (0.050" / 1.27mm), position count (20), row configuration (2 rows), connector type (Header), contact type (Male Pin), mounting type (Surface Mount), termination (Solder), and shrouding (Shrouded - 4 Wall). Secondary considerations include insulation height, contact shape, current rating, voltage rating, and operating temperature range. All listed substitutes maintain primary compatibility parameters.
