Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFW28R-2STAE1LF are identified based on the following critical parameters that must align for functional equivalence:

• Number of Positions: 28 (exact match required)
• Pitch: 0.039" (1.00mm) (exact match required)
• Mounting Type: Surface Mount, Right Angle (exact match required)
• Flat Flex Type: FPC (exact match required)
• FFC, FCB Thickness: 0.30mm (exact match required)
• Termination: Solder (exact match required)
• Locking Feature: Slide Lock (exact match required)
• Features: Zero Insertion Force (ZIF) (exact match required)
• Material Flammability Rating: UL94 V-0 (exact match required)
• Connector/Contact Type: Top or Bottom contact orientation (substitution allowed based on application)

The two identified substitutes (TE Connectivity AMP Connectors 2-84952-8 and 2-84953-8) share all critical mechanical and electrical parameters with the main part. Differences in contact finish material, housing material composition, actuator material, and voltage rating specifications are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (2-84952-8 and 2-84953-8) are active products with current production status and full inventory availability. All three parts maintain UL94 V-0 flammability compliance and MSL 1 moisture sensitivity rating.

2-84953-8 provides the closest functional match to the SFW28R-2STAE1LF, sharing identical contact orientation (top-mounted), connector type, and mechanical configuration. This part is suitable for direct substitution in applications where the operating temperature range of -40°C ~ 85°C and voltage rating of 200V are compatible with design requirements.

2-84952-8 features bottom-mounted contacts and is suitable only for applications where bottom contact orientation is functionally equivalent to the top-mounted configuration of the main part. This part also operates within -40°C ~ 85°C temperature range with 200V voltage rating.

Both TE Connectivity substitutes feature tin contact finish compared to the gold finish of the main part, and employ different housing and actuator materials (LCP and PA/Nylon versus PPS). These material differences do not affect electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can 2-84952-8 be used as a direct replacement for SFW28R-2STAE1LF?

A: 2-84952-8 shares all critical mechanical and electrical parameters (28 positions, 1.00mm pitch, surface mount right angle, FPC type, 0.30mm thickness, solder termination, slide lock, ZIF operation, UL94 V-0 rating). However, it features bottom-mounted contacts versus the top-mounted contacts of the main part. Substitution is valid only if the application design accommodates bottom contact orientation.

Q: Can 2-84953-8 be used as a direct replacement for SFW28R-2STAE1LF?

A: Yes. 2-84953-8 matches all critical parameters including top-mounted contact orientation, 28 positions, 1.00mm pitch, surface mount right angle configuration, FPC type, 0.30mm thickness, solder termination, slide lock, and ZIF operation. Both parts maintain UL94 V-0 flammability compliance and MSL 1 rating. Verify that the operating temperature range (-40°C ~ 85°C) and voltage rating (200V) are compatible with application requirements.

Q: What are the key differences between the main part and the substitutes?

A: The main part (SFW28R-2STAE1LF) features gold contact finish and PPS/glass-filled housing and actuator materials with a 100V voltage rating and -55°C ~ 105°C operating temperature range. Both TE Connectivity substitutes feature tin contact finish, LCP/glass-filled housing, PA/nylon actuator materials, 200V voltage rating, and -40°C ~ 85°C operating temperature range. All three parts share identical mechanical configuration and electrical current rating (1A).

Q: Are there any compliance or certification differences?

A: The main part is RoHS Compliant. Both substitutes are ROHS3 Compliant, which represents an updated compliance standard. All three parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level. Both substitutes are active production parts with current inventory availability.

Q: What is the significance of the contact finish difference (gold versus tin)?

A: Contact finish affects corrosion resistance and solderability characteristics. Gold finish provides superior corrosion resistance in high-humidity or corrosive environments. Tin finish is standard for solder-retained connectors and provides adequate performance in controlled manufacturing and storage environments. Selection depends on application environmental exposure requirements.

Q: How do the height above board specifications differ?

A: The main part (SFW28R-2STAE1LF) has a height of 0.106" (2.70mm) above the board. Both TE Connectivity substitutes have a height of 0.101" (2.56mm). This 0.005" (0.14mm) difference is within typical PCB layout tolerances but should be verified against specific board clearance requirements.

Q: Can the operating temperature ranges be considered equivalent?

A: The main part operates from -55°C ~ 105°C, while both substitutes operate from -40°C ~ 85°C. The substitutes have a narrower temperature range. Applications requiring operation below -40°C or above 85°C must use the main part. Applications within the -40°C ~ 85°C range can use either part.
