Substitute Part Grouping Explanation

Substitute parts for the SFM-135-02-S-D are grouped into two categories based on the following substitution criteria:

Category 1: Samtec Tiger Eye™ SFM Series Variants These parts maintain identical electrical and mechanical specifications with the main part. Substitution is determined by matching: 70-position count, 0.050" (1.27mm) pitch, 2-row configuration, surface mount termination, gold mating contact finish, 3.2A current rating, 250VAC voltage rating, -55°C to 125°C operating temperature range, and LCP insulation material. Variants within this category differ only in optional features (Board Guide, Board Lock, Pick and Place) and insulation height specifications.

Category 2: Cross-Manufacturer Equivalent The TE Connectivity part 5-104652-7 provides functional equivalence based on matching core electrical and mechanical parameters: 70-position count, 0.050" (1.27mm) pitch, 2-row configuration, surface mount termination, gold mating contact finish, and LCP insulation material. This part operates within a different temperature range (-65°C to 105°C) and uses different mated stacking heights, requiring design verification for specific application constraints.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with current manufacturing standards. The Samtec Tiger Eye™ SFM series variants (SFM-135-02-S-D-A, SFM-135-02-S-D-LC, SFM-135-02-S-D-LC-P, SFM-135-L2-S-D-A, SFM-135-L2-S-D-LC) provide direct electrical and mechanical interchangeability with identical operating temperature ranges and current/voltage ratings. These variants differ only in optional mechanical features (Board Guide, Board Lock, Pick and Place) that do not affect core connector functionality.

The TE Connectivity 5-104652-7 cross-manufacturer equivalent provides functional substitution for applications where supplier diversification is required. This part maintains identical pitch, position count, and surface mount configuration. However, the operating temperature range (-65°C to 105°C) differs from the Samtec specification (-55°C to 125°C), and mated stacking heights vary. Design verification is required to confirm compatibility with specific application thermal and mechanical constraints before implementation.

Frequently Asked Questions (FAQ)

Q: Can SFM-135-02-S-D-A be used as a direct replacement for SFM-135-02-S-D? A: Yes. Both parts share identical electrical specifications (3.2A per contact, 250VAC), mechanical dimensions (70 positions, 0.050" pitch, 2 rows), surface mount configuration, and operating temperature range (-55°C to 125°C). The SFM-135-02-S-D-A includes a Board Guide feature not present in the base model, which does not affect interchangeability.

Q: What is the difference between SFM-135-02-S-D-LC and SFM-135-02-S-D-LC-P? A: Both parts are electrically and mechanically identical. The SFM-135-02-S-D-LC-P includes an additional Pick and Place feature in addition to the Board Lock feature present in SFM-135-02-S-D-LC. These features facilitate assembly automation and do not affect connector performance or compatibility.

Q: Is the TE Connectivity 5-104652-7 a suitable substitute for the Samtec SFM-135-02-S-D? A: The 5-104652-7 provides functional equivalence for pitch, position count, and surface mount configuration. However, it operates within a narrower temperature range (-65°C to 105°C) compared to the SFM-135-02-S-D (-55°C to 125°C). Applications requiring the full Samtec temperature specification must verify that the TE part's operating range meets design requirements before substitution.

Q: What are the mated stacking height options for these connectors? A: Samtec SFM series parts offer mated stacking heights of 6.15mm, 6.30mm, 7.92mm, 8.08mm, 9.70mm, 9.86mm, 11.61mm, and 11.76mm. The TE Connectivity 5-104652-7 provides 6.35mm, 8.13mm, and 9.91mm options. Stacking height selection depends on application board-to-board spacing requirements and must be confirmed during design layout.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts, including the cross-manufacturer TE Connectivity equivalent, maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing and environmental regulations.

Q: What is the difference between the SFM-135-02 and SFM-135-L2 variants? A: The SFM-135-L2 variants (SFM-135-L2-S-D-A and SFM-135-L2-S-D-LC) maintain identical electrical and mechanical specifications as the SFM-135-02 series. The designation difference reflects internal design variations within the Tiger Eye™ SFM product line. Both series are functionally interchangeable for the specified 70-position, 0.050" pitch configuration.
