Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-140-22-S-D is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (80)
• Number of rows (2)
• Pitch - mating (0.050" / 1.27mm)
• Row spacing - mating (0.050" / 1.27mm)
• Mounting type (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Insulation material (Liquid Crystal Polymer)
• Contact material (Phosphor Bronze)
• Contact finish - mating (Gold)

The substitute part 5-104693-8 (TE Connectivity AMP Connectors) meets all critical dimensional and functional parameters required for direct substitution in board-to-board applications. Both parts share identical pitch, position count, row configuration, and mounting characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the TFM-140-22-S-D and 5-104693-8 are active production parts with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts should be based on application-specific requirements:

The TFM-140-22-S-D supports higher current capacity (2.9A per contact) and operates across a wider temperature range (-55°C to 125°C). The 5-104693-8 operates within a narrower temperature range (-65°C to 105°C) with reduced current capacity (0.5A per contact). Both parts feature identical pitch, position count, and mounting configuration, ensuring mechanical and electrical compatibility in board-to-board applications where current and temperature specifications align with the substitute part's ratings.

Frequently Asked Questions (FAQ)

Q: Can the 5-104693-8 be used as a direct replacement for the TFM-140-22-S-D?

A: The 5-104693-8 is mechanically and electrically compatible for board-to-board applications where the application current requirement does not exceed 0.5A per contact and the operating temperature range remains within -65°C to 105°C. Both parts share identical pitch (0.050"), position count (80), row configuration (2 rows), and mounting type (surface mount).

Q: What are the key differences between these two parts?

A: The primary differences are contact current rating (2.9A vs. 0.5A per contact), operating temperature range (-55°C to 125°C vs. -65°C to 105°C), contact shape (square vs. circular), and contact length (0.139" vs. 0.120"). The TFM-140-22-S-D also specifies a 275VAC voltage rating, while the 5-104693-8 does not provide a voltage specification.

Q: Are both parts RoHS compliant?

A: Yes, both the TFM-140-22-S-D and 5-104693-8 are ROHS3 compliant with UL94 V-0 flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels.

Q: What should I consider when selecting between these parts?

A: Evaluate your application's current requirements per contact, operating temperature range, and voltage specifications. The TFM-140-22-S-D is suitable for higher-current applications and wider temperature ranges. The 5-104693-8 is appropriate for lower-current applications within its specified temperature limits. Both parts are suitable for board-to-board push-pull connector applications with solder termination.
