SFV8R-2STE1 FFC/FPC Connector Equivalent & Substitute Parts

Part Overview

The SFV8R-2STE1 is an 8-position FFC/FPC connector manufactured by Amphenol ICC (FCI) designed for surface mount, right-angle applications with 0.50mm pitch contacts. This connector features zero insertion force (ZIF) operation, slide lock mechanism, and solder termination for flat flexible cable assemblies.

The SFV8R-2STE1 is classified as obsolete. Identifying equivalent and 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

Substitute parts for the SFV8R-2STE1 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or remain within acceptable tolerances for a part to function as a direct substitute:

• Number of positions: 8
• Pitch: 0.020" (0.50mm)
• Mounting type: Surface mount, right angle
• Connector/contact type: Contacts, top
• Voltage rating: 50V minimum
• Current rating: 0.5A minimum
• Operating temperature range: -55°C ~ 105°C
• Height above board: 0.071" (1.80mm)
• Termination method: Solder
• Material flammability rating: UL94 V-0
• Mating cycles: 20 minimum

The SFV8R-2STE1HLF meets all critical electrical and mechanical parameters required for substitution. Differences in locking mechanism (flip lock versus slide lock), cable end type (notched/tabbed versus straight/tapered), and housing material composition (halogen-free variants) do not affect core electrical performance or mechanical fit within the specified tolerance envelope.

Parameter Comparison

Engineering Selection Recommendations

The SFV8R-2STE1HLF is the direct substitute for the obsolete SFV8R-2STE1. Both parts share identical electrical ratings, mechanical dimensions, and core functional specifications. The substitute part is currently in active production status, ensuring supply chain availability.

The SFV8R-2STE1HLF offers additional compliance advantages: RoHS compliance and halogen-free material composition. These attributes align with modern environmental and regulatory standards. The halogen-free housing and actuator materials provide enhanced safety characteristics in thermal stress conditions.

Mechanical differences between the parts—specifically the locking mechanism (flip lock versus slide lock) and cable end type (notched/tabbed versus straight/tapered)—do not affect electrical performance or PCB-level compatibility. These design variations are accommodated within the connector interface specification and do not require circuit redesign.

The substitute part is available in tape and reel packaging, suitable for automated assembly processes. The main part's bulk packaging format is no longer relevant given the obsolete status.

Frequently Asked Questions (FAQ)

Q: Can the SFV8R-2STE1HLF be used as a direct replacement for the SFV8R-2STE1 without PCB modifications?

A: Yes. Both connectors share identical pitch (0.50mm), position count (8), mounting type (surface mount, right angle), and height above board (1.80mm). No PCB layout changes are required.

Q: What is the difference between slide lock and flip lock mechanisms?

A: Both mechanisms provide cable retention and zero insertion force operation. The slide lock uses a linear motion actuator, while the flip lock uses a rotational motion actuator. Both achieve equivalent mechanical security and electrical performance within the specified mating cycle rating of 20 cycles.

Q: Does the halogen-free material composition affect electrical performance?

A: No. Halogen-free polyamide and polyphenylene sulfide materials maintain identical electrical properties, voltage rating (50V), current rating (0.5A), and operating temperature range (-55°C ~ 105°C) as the standard material variants.

Q: Are there compatibility concerns with the different cable end types?

A: No. The straight/tapered cable end type of the main part and the notched/tabbed cable end type of the substitute are both compatible with standard 0.50mm pitch FFC/FPC cables. Cable selection depends on the specific flat flexible cable assembly design, not the connector variant.

Q: Why is RoHS compliance status different between the two parts?

A: The SFV8R-2STE1 predates RoHS compliance requirements and is classified as non-compliant. The SFV8R-2STE1HLF incorporates halogen-free materials and meets RoHS standards. For new designs or systems requiring regulatory compliance, the substitute part is the appropriate selection.

Q: What packaging format should be specified for production orders?

A: The SFV8R-2STE1HLF is supplied in tape and reel (TR) packaging, optimized for automated pick-and-place assembly. This format is standard for surface mount connectors in high-volume manufacturing environments.
