TFM-105-22-S-D-LC Equivalent & Substitute Parts

Part Overview

The TFM-105-22-S-D-LC is a surface mount rectangular connector header manufactured by Samtec Inc. in the Tiger Eye™ TFM series. This 10-position, 2-row connector operates at 0.050" (1.27mm) pitch and is designed for board-to-board or cable applications with push-pull fastening. The part is currently active in production with 906 units in stock. Equivalent and substitute parts are identified when design flexibility, inventory availability, or supply chain considerations require alternative connector options that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-105-22-S-D-LC is determined by strict alignment of the following critical parameters:

Primary Compatibility Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - Mating (0.050" / 1.27mm)
• Number of positions (10)
• Number of rows (2)
• Row spacing - Mating (0.050" / 1.27mm)
• Mounting type (Surface Mount)
• Shrouding (Shrouded - 4 Wall)
• Fastening type (Push-Pull)
• Termination (Solder)
• Contact material (Phosphor Bronze)
• Insulation material (Liquid Crystal Polymer)

Secondary Compatibility Parameters:

• Contact finish - Mating (Gold)
• Contact finish thickness - Mating (30.0µin / 0.76µm)
• Insulation color (Black)
• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1 - Unlimited)

Substitute parts are grouped based on adherence to these parameters. Variations in insulation height, contact length, current rating, voltage rating, operating temperature range, or compliance status indicate design differences that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

TFM-105-12-S-D-LC (Samtec Inc.)

This part maintains full compatibility with the TFM-105-22-S-D-LC across all primary and secondary compatibility criteria. Both parts are from the same Tiger Eye™ TFM series, share identical electrical ratings (2.9A per contact, 275VAC), and operate across the same temperature range (-55°C ~ 125°C). The only dimensional difference is insulation height (0.290" vs. 0.360"), which may affect board layout but does not impact electrical function. Both parts are ROHS3 compliant. This substitute offers higher inventory availability (3300 units) and is recommended when space constraints permit the reduced insulation height.

104693-1 (TE Connectivity AMP Connectors)

This part shares the same pitch, position count, row configuration, and mounting characteristics as the main part. However, it presents significant electrical differences: current rating is reduced to 0.5A per contact (versus 2.9A), voltage rating is not specified, and operating temperature range is narrower (-65°C ~ 105°C versus -55°C ~ 125°C). Contact shape differs (circular versus square). RoHS status is not applicable, and REACH status is affected. This part is suitable only for applications with lower current requirements and is not recommended as a direct substitute for high-current applications.

5-104693-1 (TE Connectivity AMP Connectors)

This part is functionally equivalent to 104693-1 with the same electrical limitations (0.5A per contact, no voltage rating specified, -65°C ~ 105°C operating range). The primary distinction is ROHS3 compliance status, which aligns with modern regulatory requirements. Contact shape remains circular. This part is suitable for applications with reduced current demands and is recommended over 104693-1 when RoHS3 compliance is required.

Frequently Asked Questions (FAQ)

Q: Can TFM-105-12-S-D-LC be used as a direct replacement for TFM-105-22-S-D-LC?

A: Yes, within the constraints of board layout. Both parts are electrically and mechanically identical except for insulation height. TFM-105-12-S-D-LC has a reduced insulation height of 0.290" compared to 0.360". Verify that the lower profile does not conflict with adjacent components or board design requirements.

Q: What are the key differences between Samtec and TE Connectivity options?

A: Samtec parts (TFM-105-22-S-D-LC and TFM-105-12-S-D-LC) deliver 2.9A per contact and 275VAC rating. TE Connectivity parts (104693-1 and 5-104693-1) deliver only 0.5A per contact with no specified voltage rating. Samtec parts operate to 125°C; TE Connectivity parts to 105°C. Selection depends on current and voltage requirements of the application.

Q: Are the TE Connectivity parts suitable for high-current applications?

A: No. The 0.5A per contact rating of 104693-1 and 5-104693-1 is significantly lower than the 2.9A per contact rating of Samtec parts. These TE Connectivity options are suitable only for low-current signal applications.

Q: What is the significance of contact shape differences?

A: Samtec parts feature square contacts; TE Connectivity parts feature circular contacts. Contact shape affects mating force, contact resistance, and mechanical durability. Square contacts provide different engagement characteristics than circular contacts and are not interchangeable without mating connector verification.

Q: Which substitute offers the best inventory availability?

A: TFM-105-12-S-D-LC offers the highest inventory with 3300 units in stock, compared to 906 units for the main part, 1474 units for 5-104693-1, and 692 units for 104693-1.

Q: Are all parts RoHS3 compliant?

A: TFM-105-22-S-D-LC, TFM-105-12-S-D-LC, and 5-104693-1 are ROHS3 compliant. 104693-1 has not applicable RoHS status. For applications requiring RoHS3 compliance, use TFM-105-12-S-D-LC or 5-104693-1.

Q: What is the operating temperature difference between parts?

A: Samtec parts operate from -55°C to 125°C. TE Connectivity parts operate from -65°C to 105°C. Samtec parts support higher maximum temperature; TE Connectivity parts support lower minimum temperature. Application temperature requirements determine suitability.
