SFW30R-3STAE9LF FPC Connector Equivalent & Substitute Parts

Part Overview

The SFW30R-3STAE9LF is a 30-position FPC (Flat Flexible Cable) connector manufactured by Amphenol ICC (FCI) with bottom-contact configuration and right-angle surface mount termination. This connector is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part features zero insertion force (ZIF) operation, slide lock retention, and solder termination suitable for flexible cable interconnection in compact electronic assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SFW30R-3STAE9LF is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of positions: 30
• Pitch: 0.039" (1.00mm)
• Mounting type: Surface mount, right angle
• Termination method: Solder
• Connector contact configuration: Bottom or top contact

Substitution Logic:

The parametric equivalent SFW30R-1STAE1LF maintains identical electrical and mechanical specifications with the main part, differing only in packaging (Tape & Reel) and product status (Active). This part is a direct functional replacement.

The TE Connectivity parts 3-84952-0 and 3-84953-0 are manufacturer-recommended alternatives that satisfy the core 30-position, 1.00mm pitch, surface mount, solder-terminated requirements. These parts introduce controlled parameter variations:

• 3-84952-0: Bottom-contact configuration matching the original contact placement
• 3-84953-0: Top-contact configuration requiring design verification for contact orientation compatibility

Both TE Connectivity alternatives feature enhanced voltage rating (200V vs. 100V), different housing materials (LCP vs. PPS), and tin contact finish (vs. gold), which represent functional improvements within the FPC connector category.

Parameter Comparison

Engineering Selection Recommendations

SFW30R-1STAE1LF (Amphenol ICC): This part is the primary substitute for the obsolete SFW30R-3STAE9LF. It maintains identical electrical and mechanical specifications, including voltage rating, operating temperature range, and contact configuration. The part is currently in active production status with RoHS compliance and unlimited moisture sensitivity rating. Selection of this part requires only packaging format verification (Tape & Reel availability).

3-84952-0 (TE Connectivity): This manufacturer-recommended alternative provides bottom-contact configuration matching the original part's contact placement. The part features enhanced voltage rating (200V), ROHS3 compliance, and solder retention feature. The operating temperature range (-40°C ~ 85°C) is narrower than the original specification. Selection requires verification that the reduced temperature range and tin contact finish are compatible with application requirements.

3-84953-0 (TE Connectivity): This part differs from the original in contact configuration (top vs. bottom), requiring PCB layout and cable routing verification. The top-contact orientation may necessitate design modifications. This part is suitable only when contact orientation change is acceptable and verified through design review.

Frequently Asked Questions (FAQ)

Q: Can SFW30R-1STAE1LF be used as a direct replacement for SFW30R-3STAE9LF?

A: Yes. Both parts share identical electrical and mechanical specifications: 30 positions, 1.00mm pitch, bottom-contact configuration, surface mount right-angle termination, 100V voltage rating, and -55°C to 105°C operating temperature. The primary difference is packaging format (Tape & Reel for the substitute) and active production status.

Q: What are the key differences between the Amphenol and TE Connectivity substitutes?

A: The TE Connectivity parts (3-84952-0 and 3-84953-0) feature higher voltage rating (200V vs. 100V), different housing material (LCP vs. PPS), tin contact finish (vs. gold), and narrower operating temperature range (-40°C to 85°C vs. -55°C to 105°C). The 3-84952-0 maintains bottom-contact configuration, while 3-84953-0 uses top-contact configuration.

Q: Is the contact finish difference (gold vs. tin) significant for substitution?

A: Contact finish affects corrosion resistance and solderability. Gold finish provides superior corrosion resistance and is preferred for long-term storage and harsh environments. Tin finish is acceptable for standard applications with controlled environmental conditions. Application requirements determine acceptability.

Q: Can 3-84953-0 be used if the original design requires bottom-contact configuration?

A: No. The 3-84953-0 features top-contact configuration, which changes the cable attachment orientation. This requires PCB layout modification and cable routing verification. Use only when design changes are feasible and validated.

Q: Are all substitute parts RoHS compliant?

A: Yes. The SFW30R-1STAE1LF is RoHS Compliant. The TE Connectivity parts (3-84952-0 and 3-84953-0) are ROHS3 Compliant, representing enhanced RoHS compliance standards.

Q: What is the inventory status for these substitute parts?

A: SFW30R-1STAE1LF: 840 pcs in stock. 3-84952-0: 11,826 pcs in stock. 3-84953-0: 14,354 pcs in stock. Availability supports production requirements across all substitute options.
