SFV26R-2STE1 FFC/FPC Connector - Equivalent & Substitute Parts

Part Overview

The SFV26R-2STE1 is a 26-position FFC/FPC connector manufactured by Amphenol ICC (FCI) designed for surface mount, right-angle applications with 0.5mm pitch contacts. This connector features zero insertion force (ZIF) operation, slide lock retention, and solder termination for flat flexible cable assemblies.

The SFV26R-2STE1 is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or repair requirements for systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFV26R-2STE1 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Voltage rating (50V), current rating (0.5A), and operating temperature range (-55°C ~ 105°C) must be identical or exceed the original specification.
• Mechanical Compatibility: Number of positions (26), pitch (0.5mm), mounting type (surface mount, right angle), connector/contact type (contacts, top), and height above board (1.80mm) must match exactly.
• Functional Features: Zero insertion force (ZIF) operation and slide lock retention must be present.
• Termination Method: Solder termination is required.
• Flammability Compliance: UL94 V-0 rating must be maintained.

The substitute part SFV26R-2STE1HLF meets all these criteria while offering improved product status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the SFV26R-2STE1HLF be used as a direct replacement for the SFV26R-2STE1 without PCB redesign?

A: Yes. The SFV26R-2STE1HLF is mechanically and electrically identical to the SFV26R-2STE1. All critical dimensions, pitch, mounting type, and electrical ratings are equivalent. No PCB layout changes are required.

Q: What is the difference between the two part numbers?

A: The primary differences are product status, regulatory compliance, and packaging. The SFV26R-2STE1HLF is an active product with RoHS compliance and halogen-free materials, while the SFV26R-2STE1 is obsolete and RoHS non-compliant. The "HLF" suffix indicates halogen-free construction.

Q: Are there any compatibility concerns with cable thickness?

A: The SFV26R-2STE1 supports FFC/FPC thickness of 0.30mm and 0.33mm. The SFV26R-2STE1HLF supports 0.33mm thickness. Verify that your cable assembly uses 0.33mm thickness for full compatibility with the substitute part.

Q: What packaging options are available?

A: The SFV26R-2STE1 was supplied in bulk packaging. The SFV26R-2STE1HLF is available in Tape & Reel (TR) format, which is standard for automated assembly operations.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both connectors operate across the identical temperature range of -55°C to 105°C and maintain the same voltage (50V) and current (0.5A) ratings.
