Equivalent & Substitute Parts for TFM-120-02-S-D

Part Overview

The TFM-120-02-S-D is a surface mount rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFM series. This 40-position, 2-row connector with 0.050" (1.27mm) pitch is designed for board-to-board or cable applications with push-pull fastening. The part is currently active in production with 733 units in stock. Alternative equivalent parts may be required due to supply chain considerations, packaging preferences, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-120-02-S-D is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 40 positions in 2 rows
• Pitch Specification: 0.050" (1.27mm) mating pitch and row spacing
• Mounting Technology: Surface mount solder termination
• Shrouding & Fastening: 4-wall shrouded with push-pull fastening
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Finish: Gold-plated mating surface

The substitute parts identified—104655-5 and 5-104655-5 from TE Connectivity AMP Connectors (AMPMODU 50/50 Grid series)—share identical specifications for connector type, position count, row configuration, pitch, mounting type, shrouding, fastening mechanism, insulation material, and contact finish. These parts are mechanically and electrically compatible for board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity substitute parts (104655-5 and 5-104655-5) are mechanically and electrically compatible with the TFM-120-02-S-D for board-to-board connector applications. All three parts maintain active product status and UL94 V-0 flammability compliance.

5-104655-5 (Bulk Packaging) is the preferred substitute when RoHS3 compliance and REACH unaffected status are required, as it matches the TFM-120-02-S-D compliance profile. This part is available in bulk packaging rather than tube.

104655-5 (Tube Packaging) maintains tube packaging consistency with the original part but carries RoHS non-compliant and REACH affected designations. This part is suitable only for applications where RoHS3 and REACH compliance are not mandated.

Minor dimensional variations exist: the TE Connectivity parts feature circular contact shapes versus the square contacts of the Samtec part, and mating contact length differs by 0.011" (0.28mm). These variations remain within acceptable tolerances for standard board-to-board mating applications.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts mechanically compatible with the TFM-120-02-S-D?

A: Yes. Both substitute parts share identical pitch (0.050"), row spacing (0.050"), position count (40 in 2 rows), shrouding configuration (4-wall), and fastening type (push-pull). Mating is compatible for board-to-board applications.

Q: What is the difference between 104655-5 and 5-104655-5?

A: The primary difference is packaging: 104655-5 is supplied in tube packaging, while 5-104655-5 is supplied in bulk packaging. Additionally, 5-104655-5 is ROHS3 compliant and REACH unaffected, whereas 104655-5 is RoHS non-compliant and REACH affected.

Q: Do the contact shape differences affect compatibility?

A: The TFM-120-02-S-D features square contacts while the TE Connectivity substitutes feature circular contacts. Both geometries are standard for 0.050" pitch connectors and maintain electrical and mechanical compatibility in board-to-board mating applications.

Q: What is the operating temperature difference?

A: The TFM-120-02-S-D operates from -55°C to 125°C, while both TE Connectivity substitutes operate from -65°C to 105°C. The Samtec part provides higher maximum temperature capability; the TE Connectivity parts provide lower minimum temperature capability.

Q: Which substitute should I select for RoHS3 compliant applications?

A: Select 5-104655-5. This part is ROHS3 compliant and REACH unaffected, matching the compliance status of the original TFM-120-02-S-D.

Q: Are there current rating differences?

A: Yes. The TFM-120-02-S-D is rated at 2.9A per contact, while both TE Connectivity substitutes are rated at 0.5A per contact. Applications requiring higher current per contact must use the original Samtec part.
