SFW24R-1STE1 FFC/FPC Connector Equivalent & Substitute Parts

Part Overview

The SFW24R-1STE1 is a 24-position FFC/FPC connector manufactured by Amphenol ICC (FCI) with bottom-mounted contacts, 1.00mm pitch, and right-angle surface mount configuration. This connector features Zero Insertion Force (ZIF) operation with slide lock functionality and is designed for flat flexible cable applications.

The SFW24R-1STE1 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFW24R-1STE1 are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Number of Positions: 24
• Pitch: 0.039" (1.00mm)
• Mounting Type: Surface Mount, Right Angle
• Termination: Solder
• Flat Flex Type: FFC or FPC
• Features: Zero Insertion Force (ZIF)

Acceptable Variations:

• Connector/Contact Type: Bottom or Top mounting orientation
• Height Above Board: Minor variations within 0.012" (0.30mm) tolerance
• Housing Material: Alternative polymers (PPS, LCP) with equivalent mechanical properties
• Locking Feature: Presence or absence of slide lock mechanism
• Contact Finish: Tin or Tin Alloy
• Product Status: Active status preferred for obsolete parts

The identified substitutes maintain the core electrical and mechanical interface requirements while offering improved availability and compliance status.

Parameter Comparison

Engineering Selection Recommendations

SFW24R-1STE1LF (Direct Amphenol ICC Substitute)

The SFW24R-1STE1LF is the primary substitute for the obsolete SFW24R-1STE1. Both connectors share identical mechanical interfaces, contact positioning, and mounting characteristics. The SFW24R-1STE1LF maintains active product status with RoHS compliance and improved electrical specifications (100V rating, 1A current rating, -55°C to 105°C operating range). The packaging format (Tape & Reel) supports automated assembly processes. This substitute is recommended for direct replacement in new designs and production continuity.

ZF1-24-02-T-WT-TR (Cross-Manufacturer Alternative)

The ZF1-24-02-T-WT-TR from Samtec Inc. provides an alternative from a different manufacturer while maintaining core compatibility parameters. This connector features identical pitch, position count, and right-angle surface mount configuration. The primary difference is top-mounted contacts versus bottom-mounted contacts on the original part, requiring PCB layout modification. The ZF1-24-02-T-WT-TR carries active product status with ROHS3 compliance. Height above board is 0.012" (0.30mm) greater than the original specification. This substitute is suitable for applications where cross-manufacturer sourcing is acceptable and PCB redesign is feasible.

Frequently Asked Questions (FAQ)

Q: Can SFW24R-1STE1LF be used as a direct replacement for SFW24R-1STE1?

A: Yes. Both connectors share identical mechanical interfaces, pitch, position count, mounting type, and contact orientation. The SFW24R-1STE1LF is the active production equivalent with improved compliance status and electrical specifications.

Q: What is the primary difference between SFW24R-1STE1LF and ZF1-24-02-T-WT-TR?

A: The SFW24R-1STE1LF features bottom-mounted contacts, while the ZF1-24-02-T-WT-TR features top-mounted contacts. This difference requires PCB layout modification. Additionally, the ZF1-24-02-T-WT-TR is 0.012" (0.30mm) taller and uses Liquid Crystal Polymer (LCP) housing instead of PPS.

Q: Are there compatibility concerns with cable thickness?

A: The SFW24R-1STE1 accepts FFC/FCB thickness of 0.30mm and 0.33mm. The SFW24R-1STE1LF accepts 0.30mm thickness only. The ZF1-24-02-T-WT-TR accepts 0.30mm thickness. Verify cable thickness compatibility before selection.

Q: What is the impact of RoHS compliance differences?

A: The original SFW24R-1STE1 is RoHS non-compliant. Both substitutes (SFW24R-1STE1LF and ZF1-24-02-T-WT-TR) are RoHS compliant. For applications subject to RoHS regulations, the substitutes are required.

Q: Does the locking feature differ between substitutes?

A: The SFW24R-1STE1 and ZF1-24-02-T-WT-TR both feature slide lock mechanisms. The SFW24R-1STE1LF locking feature is not specified in available documentation.

Q: What packaging formats are available?

A: Both substitutes are supplied in Tape & Reel (TR) format, supporting automated assembly processes. The original SFW24R-1STE1 packaging format is not specified.
