SFW14R-2STE9LF Equivalent & Substitute Parts

Part Overview

The SFW14R-2STE9LF is a 14-position FFC/FPC connector manufactured by Amphenol ICC (FCI) with top-mounted contacts, right-angle surface mount configuration, and 1.00mm pitch. This connector features zero insertion force (ZIF) operation with slide lock actuation, designed for flexible cable termination in compact applications. The part is currently obsolete, making identification of functional equivalents essential for legacy system maintenance and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SFW14R-2STE9LF is determined by strict equivalence across the following critical parameters:

• Connector Position Count: 14 positions (non-negotiable for circuit compatibility)
• Pitch Specification: 0.039" (1.00mm) (determines cable and PCB layout compatibility)
• Mounting Configuration: Surface mount, right-angle orientation (required for board space and mechanical fit)
• Contact Arrangement: Top-mounted contacts (defines signal routing and mating interface)
• Electrical Ratings: 100V voltage, 1A current (ensures safe operation within design margins)
• Operating Temperature Range: -55°C ~ 105°C (validates thermal compatibility)
• Locking Mechanism: Slide lock with ZIF operation (ensures reliable connection retention)
• Material Specifications: Phosphor bronze contacts with tin finish; PPS glass-filled housing and actuator (maintains mechanical and electrical performance)
• Compliance Standards: RoHS compliant, UL94 V-0 flammability rating (meets regulatory requirements)

The SFW14R-2STE5LF qualifies as a parametric equivalent based on identical electrical, mechanical, and material specifications across all critical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The SFW14R-2STE5LF is the direct parametric equivalent for the obsolete SFW14R-2STE9LF. Both parts share identical electrical specifications, mechanical dimensions, material composition, and compliance certifications. The primary distinction is product status: the SFW14R-2STE5LF is currently active and available in production quantities, while the original part is obsolete.

The packaging difference (Cut Tape versus Tape & Reel) reflects standard industry practice for active versus legacy products and does not affect functional compatibility. Both packaging formats deliver the same connector with identical performance characteristics.

For new designs or legacy system replacements, the SFW14R-2STE5LF provides full functional continuity with the original specification while ensuring long-term supply availability and compliance with current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the SFW14R-2STE5LF directly replace the SFW14R-2STE9LF in existing designs?

A: Yes. Both connectors are electrically and mechanically identical across all critical parameters: 14-position configuration, 1.00mm pitch, surface mount right-angle mounting, 100V/1A ratings, -55°C to 105°C operating range, and identical material specifications. Direct substitution is supported without design modification.

Q: What is the significance of the packaging difference between Cut Tape and Tape & Reel?

A: Packaging format affects order quantity and handling logistics but does not impact connector performance or compatibility. Cut Tape is typical for legacy or low-volume products; Tape & Reel is standard for active production parts. Both deliver identical connectors suitable for the same applications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical certifications: RoHS compliant, UL94 V-0 flammability rating, and MSL 1 (unlimited moisture sensitivity). Compliance status is equivalent.

Q: Why is the original part marked as obsolete?

A: Product obsolescence reflects manufacturing lifecycle decisions by Amphenol ICC (FCI). The SFW14R-2STE5LF remains in active production and provides full functional equivalence, ensuring continued availability for applications requiring this connector specification.

Q: Are the electrical and thermal performance characteristics identical?

A: Yes. Both parts specify 100V voltage rating, 1A current rating, and -55°C to 105°C operating temperature range. Electrical performance, thermal behavior, and reliability characteristics are equivalent.

Q: Can these connectors be used interchangeably in high-reliability applications?

A: Yes, provided the application requirements align with the specified ratings. Both connectors meet the same electrical, mechanical, and environmental specifications. The 20 mating cycle rating applies to both parts and should be evaluated against specific application duty cycles.
