Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFC-125-02-F-D is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (50)
• Number of rows (2)
• Pitch spacing (0.050" / 1.27mm)
• Row spacing (0.050" / 1.27mm)
• Mounting type (Surface Mount)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Current rating (3.1A per Contact)
• Voltage rating (275VAC)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The identified substitute maintains all electrical and mechanical specifications. Variations in features such as board guide presence do not affect functional interchangeability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TFC-125-02-F-D and TFC-125-02-F-D-A are active products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability: TFC-125-02-F-D has 1010 units in stock; TFC-125-02-F-D-A has 908 units in stock
• Feature requirements: TFC-125-02-F-D-A includes a board guide feature not present in the base model
• Supply chain considerations: Both parts carry ROHS3 compliance and identical regulatory certifications

Either part satisfies the electrical and mechanical requirements for applications requiring a 50-position, 0.050" pitch surface mount header with push-pull fastening and 3.1A per contact current capacity.

Frequently Asked Questions (FAQ)

Q: Can TFC-125-02-F-D and TFC-125-02-F-D-A be used interchangeably?

A: Yes. Both parts maintain identical electrical specifications (275VAC, 3.1A per contact), mechanical dimensions (50 positions, 0.050" pitch, 2 rows), operating temperature range (-55°C ~ 125°C), and contact materials. The board guide feature in the TFC-125-02-F-D-A does not affect electrical interchangeability.

Q: What determines substitution eligibility for this connector?

A: Substitution is valid when parts share identical pitch spacing (0.050"), position count (50), row configuration (2 rows), mounting type (surface mount), contact type (male pin), fastening method (push-pull), current rating (3.1A per contact), and voltage rating (275VAC).

Q: Are both parts RoHS compliant?

A: Yes. Both TFC-125-02-F-D and TFC-125-02-F-D-A are ROHS3 compliant with UL94 V-0 material flammability rating.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these connectors operate in the full temperature range specified?

A: Yes. Both parts are rated for continuous operation from -55°C to 125°C, suitable for industrial and automotive applications.
