Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-120-02-S-D-P-TR is determined by the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (40), mating pitch (0.050"), number of rows (2), row spacing (0.050"), mounting type (surface mount), termination method (solder), and fastening type (push-pull). All identified substitute parts maintain these core electrical and mechanical specifications.

The substitute parts are grouped into two categories:

Category 1: Samtec Tiger Eye™ SFM Series Variant SFM-120-02-S-D-K-TR differs only in fastening mechanism designation (K vs. P) while maintaining identical electrical performance, pitch, position count, and thermal ratings.

Category 2: TE Connectivity AMPMODU 50/50 Grid Series Parts 104652-4 and 5-104652-4 provide functional equivalence across all critical mating and mounting parameters. These parts operate within the same pitch and position specifications but originate from a different manufacturer series with distinct compliance and packaging characteristics.

Parameter Comparison

Engineering Selection Recommendations

SFM-120-02-S-D-K-TR (Samtec Inc.) This part is functionally equivalent to the primary part number with identical electrical and mechanical specifications. Both are ROHS3 compliant and active in production. Selection between SFM-120-02-S-D-P-TR and SFM-120-02-S-D-K-TR depends on packaging availability and inventory requirements, as both are supplied in Tape & Reel format.

104652-4 (TE Connectivity AMP Connectors) This part maintains all critical mating and mounting parameters but is RoHS non-compliant and supplied in Tube packaging rather than Tape & Reel. Selection is appropriate only for applications where RoHS compliance is not required. Operating temperature range is -65°C to 105°C, which is narrower than the Samtec alternative at the upper limit (105°C vs. 125°C).

5-104652-4 (TE Connectivity AMP Connectors) This part is functionally equivalent across all critical parameters and is ROHS3 compliant, matching the primary part's compliance status. It is supplied in Tube packaging. Operating temperature range is -65°C to 105°C. This part provides cross-manufacturer substitution with full regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can SFM-120-02-S-D-K-TR be used as a direct replacement for SFM-120-02-S-D-P-TR? A: Yes. Both parts are from the Samtec Tiger Eye™ SFM series with identical electrical ratings, pitch specifications, position count, and thermal operating range. The designation difference (K vs. P) does not affect functional compatibility. Both are ROHS3 compliant and supplied in Tape & Reel packaging.

Q: What are the key differences between Samtec and TE Connectivity options? A: The primary differences are manufacturer series origin and contact material composition. Samtec parts use Beryllium Copper contacts, while TE Connectivity AMPMODU parts use Copper Alloy contacts. TE Connectivity parts are supplied in Tube packaging rather than Tape & Reel. Operating temperature upper limit differs: Samtec supports -55°C to 125°C, while TE Connectivity supports -65°C to 105°C.

Q: Is 104652-4 suitable for new designs? A: The 104652-4 is RoHS non-compliant and not recommended for new designs requiring regulatory compliance. The 5-104652-4 variant is ROHS3 compliant and is the appropriate TE Connectivity option for new applications.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel and Tube packaging formats do not affect electrical or mechanical performance. Selection between packaging types is based on assembly process requirements and inventory management practices.

Q: Are there current or voltage rating differences between substitutes? A: The primary part specifies 3.2A per contact at 250VAC. TE Connectivity parts do not provide explicit current or voltage ratings in the available specifications. For applications requiring confirmed current and voltage ratings, Samtec parts provide explicit specifications.

Q: What is the significance of the 0.050" insulation height difference? A: The primary part has 0.185" (4.70mm) insulation height, while TE Connectivity parts have 0.187" (4.75mm). This 0.002" (0.05mm) difference is within typical manufacturing tolerance and does not affect functional compatibility in standard board-to-board applications.
