SFV7R-2STE1 FFC/FPC Connector Equivalent & Substitute Parts

Part Overview

The SFV7R-2STE1 is a 7-position FFC/FPC connector manufactured by Amphenol ICC (FCI), designed for surface mount, right-angle applications with 0.020" (0.50mm) pitch contacts. This connector features a slide lock mechanism, zero insertion force (ZIF) operation, and solder termination for flat flexible cable assemblies.

The SFV7R-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 SFV7R-2STE1 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or be compatible:

• Position Count: 7 positions (mandatory match)
• Pitch: 0.020" (0.50mm) (mandatory match)
• Mounting Type: Surface mount, right angle (mandatory match)
• Connector/Contact Type: FFC/FPC contacts, top (mandatory match)
• Termination: Solder (mandatory match)
• Locking Feature: Slide lock (mandatory match)
• Voltage Rating: Minimum 50V
• Current Rating: Minimum 0.5A
• Operating Temperature Range: Must encompass or exceed -55°C ~ 105°C
• Flammability Rating: UL94 V-0

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

SFV7R-2STE1HLF is the primary substitute for the obsolete SFV7R-2STE1. Both connectors are manufactured by Amphenol ICC (FCI) within the same SFV-R series. The SFV7R-2STE1HLF maintains identical electrical and mechanical specifications, including voltage rating, current rating, operating temperature range, and board height. The primary distinction is product status: SFV7R-2STE1HLF is active and available in production quantities. Additionally, SFV7R-2STE1HLF is RoHS compliant and halogen-free, meeting modern environmental and regulatory requirements. Packaging is supplied as Tape & Reel (TR).

1734839-7 is an alternative substitute manufactured by TE Connectivity AMP Connectors. This connector maintains the same position count, pitch, mounting type, and locking mechanism. However, the following differences apply: height above board is 0.081" (2.05mm) versus 0.071" (1.80mm), operating temperature range is -20°C ~ 85°C (narrower than the original), and contact finish is gold rather than tin. The voltage rating is 250V, exceeding the original 50V specification. This connector is suitable for applications where the increased board height and narrower temperature range are acceptable, and where gold contact finish is preferred or required.

Frequently Asked Questions (FAQ)

Q: Can SFV7R-2STE1HLF be used as a direct replacement for SFV7R-2STE1?

A: Yes. SFV7R-2STE1HLF is a direct substitute. Both connectors share identical position count (7), pitch (0.50mm), mounting configuration (surface mount, right angle), height above board (1.80mm), voltage rating (50V), current rating (0.5A), and operating temperature range (-55°C ~ 105°C). The primary advantage is that SFV7R-2STE1HLF is active and RoHS compliant.

Q: What are the key differences between SFV7R-2STE1HLF and 1734839-7?

A: The primary differences are: (1) board height is 0.081" (2.05mm) for 1734839-7 versus 0.071" (1.80mm) for SFV7R-2STE1HLF, (2) operating temperature range is -20°C ~ 85°C for 1734839-7 versus -55°C ~ 105°C for SFV7R-2STE1HLF, (3) contact finish is gold for 1734839-7 versus tin for SFV7R-2STE1HLF, and (4) manufacturer is TE Connectivity for 1734839-7 versus Amphenol ICC for SFV7R-2STE1HLF.

Q: Is 1734839-7 suitable for applications requiring the full -55°C ~ 105°C temperature range?

A: No. The 1734839-7 operating temperature range is -20°C ~ 85°C, which does not encompass the original specification of -55°C ~ 105°C. Use 1734839-7 only in applications where the narrower temperature range is acceptable.

Q: What is the impact of the increased board height in 1734839-7?

A: The 1734839-7 has a board height of 0.081" (2.05mm) compared to 0.071" (1.80mm) for the original and SFV7R-2STE1HLF. This 0.010" (0.25mm) increase may affect PCB layout, clearance to adjacent components, or mechanical fit within the enclosure. Verify board height compatibility before selection.

Q: Are there packaging differences between the substitute parts?

A: Both SFV7R-2STE1HLF and 1734839-7 are supplied in Tape & Reel (TR) packaging. The original SFV7R-2STE1 packaging is not specified in the provided data.

Q: What is the significance of RoHS compliance for these connectors?

A: SFV7R-2STE1HLF is RoHS compliant, meeting EU Directive 2011/65/EU requirements for restricted hazardous substances. The original SFV7R-2STE1 is non-compliant. For applications subject to RoHS requirements, SFV7R-2STE1HLF is the appropriate selection.
