TFC-120-02-LM-D-A Equivalent & Substitute Parts

Part Overview

The TFC-120-02-LM-D-A is a surface mount rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFC series. This 40-position connector operates at 0.050" (1.27mm) pitch and is designed for board-to-board or cable applications. The part is currently active in production with 1011 units in stock. Alternative models may be required due to inventory constraints, application-specific requirements, or design revisions.

Key Parameters

Substitute Part Grouping Explanation

The TFC-120-02-L-D-A qualifies as a direct substitute based on the following critical parameters:

• Identical manufacturer (Samtec Inc.)
• Same series (Tiger Eye™ TFC)
• Matching connector type (Header) and contact type (Male Pin)
• Identical position count (40 positions, 2 rows)
• Identical pitch specifications (0.050" mating pitch, 0.050" row spacing)
• Identical mounting type (Surface Mount)
• Identical shrouding configuration (Shrouded - 4 Wall)
• Matching electrical ratings (3.1A per contact, 275VAC)
• Identical operating temperature range (-55°C ~ 125°C)
• Equivalent compliance status (ROHS3 Compliant)

The substitution is valid because all critical electrical, mechanical, and environmental parameters are identical between the main part and the substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the TFC-120-02-LM-D-A and TFC-120-02-L-D-A are active production parts with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on inventory availability and lead time requirements. The TFC-120-02-LM-D-A currently has higher stock levels (1011 units) compared to the TFC-120-02-L-D-A (944 units). Both parts meet identical electrical, mechanical, and environmental specifications and are suitable for direct substitution in applications requiring 40-position, 0.050" pitch surface mount headers with 3.1A per contact current capacity and 275VAC voltage rating.

Frequently Asked Questions (FAQ)

Q: Can TFC-120-02-L-D-A be used as a direct replacement for TFC-120-02-LM-D-A?

A: Yes. All critical parameters including pitch, position count, row configuration, mounting type, shrouding, electrical ratings, and operating temperature range are identical. Both parts are from the same Tiger Eye™ TFC series and carry equivalent compliance certifications.

Q: What are the key parameters that determine substitutability for this connector?

A: The critical parameters are: connector type (Header), contact type (Male Pin), number of positions (40), number of rows (2), mating pitch (0.050"), row spacing (0.050"), mounting type (Surface Mount), shrouding configuration (Shrouded - 4 Wall), current rating (3.1A per contact), and voltage rating (275VAC).

Q: Are there any differences in packaging or handling between these parts?

A: Both parts are supplied in tube packaging with identical moisture sensitivity level (MSL 1 - Unlimited), indicating no special storage or handling requirements.

Q: What is the difference between the part numbers TFC-120-02-LM-D-A and TFC-120-02-L-D-A?

A: The part numbers differ in the fourth position character (LM versus L). Both parts share the same base product number (TFC-120) and are functionally equivalent across all specified electrical and mechanical parameters.

Q: Which part should be selected based on current inventory?

A: Selection should be based on application requirements and lead time. The TFC-120-02-LM-D-A has higher current inventory (1011 units), while the TFC-120-02-L-D-A has 944 units available. Both are active production parts.
