SFW7R-2STE1LF Equivalent & Substitute Parts

Part Overview

The SFW7R-2STE1LF is a 7-position FFC/FPC connector manufactured by Amphenol ICC (FCI) with top-mounted contacts, 1.00mm pitch, and right-angle surface mount configuration. This connector is currently in active product status. Substitute parts may be required due to supply constraints, design revisions, or application-specific performance requirements where alternative electrical and mechanical specifications are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFW7R-2STE1LF is determined by the following critical parameters:

• Number of Positions: Must be 7
• Pitch: Must be 0.039" (1.00mm)
• Mounting Type: Must be Surface Mount, Right Angle
• Voltage Rating: Minimum 100V
• Current Rating: Minimum 1A
• Operating Temperature Range: Must encompass or exceed -55°C ~ 105°C

The substitute parts listed below meet these core electrical and mechanical requirements. Variations in contact material finish, housing material, termination type, and mating cycles are acceptable within the scope of FFC/FPC connector substitution.

Parameter Comparison

Engineering Selection Recommendations

0522070733 (Molex Easy-On 52207): This part meets the core electrical requirements with 125V voltage rating and 1A current rating, exceeding the SFW7R-2STE1LF specifications. However, this part is marked as obsolete. The operating temperature range (-40°C ~ 85°C) is narrower than the main part. Substitution is electrically feasible but subject to product lifecycle considerations.

0528520770 (Molex Easy-On 52852): This part shares the same pitch and position count but differs in contact position (bottom vs. top) and has reduced electrical ratings (50V voltage, 0.5A current). The operating temperature range (-20°C ~ 80°C) is significantly narrower. This part is suitable only for applications where the reduced electrical specifications and bottom-contact configuration are compatible with the design.

Frequently Asked Questions (FAQ)

Q: Can 0522070733 be used as a direct replacement for SFW7R-2STE1LF?

A: Electrically, yes. Both parts share 7 positions, 1.00mm pitch, top-contact configuration, and right-angle surface mount. However, 0522070733 is obsolete, and the operating temperature range is narrower (-40°C ~ 85°C vs. -55°C ~ 105°C). Verify application temperature requirements before substitution.

Q: Is 0528520770 compatible with SFW7R-2STE1LF?

A: No, not as a direct replacement. The bottom-contact configuration is mechanically incompatible with top-contact designs. Additionally, the voltage rating (50V) and current rating (0.5A) are below the main part specifications. This part is suitable only for distinct applications with different electrical and mechanical requirements.

Q: What are the key differences in termination between these parts?

A: SFW7R-2STE1LF uses kinked pin termination, while both Molex substitutes use solder termination. This affects PCB assembly compatibility and requires verification of board design and assembly process.

Q: Are all parts RoHS compliant?

A: Yes. SFW7R-2STE1LF is RoHS Compliant. Both Molex parts are ROHS3 Compliant, meeting current regulatory requirements.

Q: What is the significance of mating cycle ratings?

A: SFW7R-2STE1LF is rated for 20 mating cycles, 0522070733 for 30 cycles, and 0528520770 for 10 cycles. Higher ratings indicate greater mechanical durability for repeated connection/disconnection operations. Select based on application usage patterns.
