SFW7R-2STE9LF Equivalent & Substitute Parts

Part Overview

The SFW7R-2STE9LF 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 classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part features zero insertion force (ZIF) operation, slide lock retention, and is rated for 100V and 1A per contact.

Substitute Part Grouping Explanation

Substitution for the SFW7R-2STE9LF is determined by the following critical parameters:

Primary Compatibility Criteria:

Number of positions: 7
Pitch: 0.039" (1.00mm)
Mounting type: Surface mount, right angle
Connector contact type: Top-mounted contacts
Termination method: Solder
Locking mechanism: Slide lock
FFC/FPC thickness: 0.30mm

Identified Substitutes:

0522070733 (Molex Easy-On 52207) – Primary substitute. Matches all critical parameters including 7 positions, 1.00mm pitch, top contacts, right-angle surface mount, slide lock, and 0.30mm FFC thickness. Packaging available in Cut Tape (CT).
0528520770 (Molex Easy-On 52852) – Partial compatibility. Matches position count, pitch, and mounting type but differs in contact orientation (bottom-mounted instead of top-mounted) and lacks slide lock feature. This part is not a direct substitute for top-contact applications.

Engineering Selection Recommendations

For direct replacement of SFW7R-2STE9LF:

The Molex 0522070733 (Easy-On 52207 series) is the recommended substitute. It maintains functional equivalence across all critical parameters: 7-position configuration, 1.00mm pitch, top-contact orientation, right-angle surface mount, slide lock retention, and identical board height. Both parts are RoHS compliant and rated for 1A continuous current. The 0522070733 offers improved availability (7258 units in stock versus 1075 for the original part) and is available in Cut Tape packaging. Operating temperature range is narrower (-40°C to 85°C versus -55°C to 105°C), and voltage rating is higher (125V versus 100V), making it suitable for most applications within the original design envelope.

Regarding the Molex 0528520770:

This part is not recommended as a substitute for the SFW7R-2STE9LF due to fundamental design differences. The bottom-contact configuration, absence of slide lock, reduced voltage rating (50V), and lower current rating (0.5A) make it incompatible with applications designed for the original top-contact connector. Use of this part would require PCB redesign and circuit re-evaluation.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0522070733 be used as a direct drop-in replacement for the SFW7R-2STE9LF?

A: Yes, for applications within the operating temperature range of -40°C to 85°C and voltage requirements up to 125V. The 0522070733 maintains identical pitch (1.00mm), position count (7), contact orientation (top), mounting configuration (right-angle surface mount), and board height (2.70mm). PCB footprints are compatible.

Q: What is the key difference between the 0522070733 and 0528520770?

A: The primary difference is contact orientation. The 0522070733 features top-mounted contacts with slide lock retention, matching the original SFW7R-2STE9LF design. The 0528520770 has bottom-mounted contacts without locking mechanism and is rated for lower voltage (50V) and current (0.5A). These are not interchangeable.

Q: Are there packaging differences between the main part and the 0522070733 substitute?

A: Yes. The SFW7R-2STE9LF packaging is not specified in available data. The 0522070733 is available in Cut Tape (CT) packaging. Confirm packaging requirements for your procurement process.

Q: Does the 0522070733 support the full operating temperature range of the original part?

A: No. The 0522070733 operates from -40°C to 85°C, while the SFW7R-2STE9LF operates from -55°C to 105°C. For applications requiring the full original temperature range, alternative solutions must be evaluated.

Q: Are both the original part and substitute RoHS compliant?

A: Yes. The SFW7R-2STE9LF is RoHS Compliant. The 0522070733 is ROHS3 Compliant, meeting current regulatory requirements.
