Substitute Part Grouping Explanation

Substitution for the SFW30R-2STE1 is determined by strict alignment of the following critical parameters:

Position Count & Pitch: 30 positions at 0.039" (1.00mm) pitch (non-negotiable for cable compatibility)
Contact Configuration: Top-contact orientation (determines PCB layout compatibility)
Mounting Style: Surface mount, right-angle termination
Termination Method: Solder attachment
Locking Mechanism: Slide lock retention
Housing & Actuator Materials: Polyphenylene Sulfide (PPS)
Flammability Rating: UL94 V-0

Substitutes are grouped into two categories:

Direct Equivalent (Same Manufacturer): SFW30R-2STE1LF maintains identical electrical and mechanical specifications while offering active product status and improved compliance.

Cross-Manufacturer Alternatives: Würth Elektronik parts (68613014122 and 68613014422) provide functional equivalence with differing contact configurations and operating parameters. The 68613014122 maintains top-contact configuration; the 68613014422 uses bottom-contact configuration and is not interchangeable without PCB redesign.

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Option): SFW30R-2STE1LF is the preferred substitute. It maintains identical mechanical and electrical specifications while offering active product status and RoHS compliance. This part is sourced from the same manufacturer and requires no PCB or assembly modifications.

For RoHS3 Compliance Requirements: Würth Elektronik 68613014122 provides an alternative with ROHS3 certification. The top-contact configuration ensures PCB layout compatibility with the original design. Note the increased height above board (2.95mm vs. 2.70mm) and narrower operating temperature range (-25°C ~ 85°C vs. -55°C ~ 105°C).

Not Recommended for Direct Substitution: Würth Elektronik 68613014422 features bottom-contact configuration and is not mechanically or electrically interchangeable without PCB redesign. This part is listed as a cross-reference only and requires engineering evaluation for new designs.

Frequently Asked Questions (FAQ)

Q: Can SFW30R-2STE1LF be used as a direct drop-in replacement for SFW30R-2STE1?

A: Yes. SFW30R-2STE1LF maintains identical pitch (1.00mm), position count (30), contact configuration (top), mounting style (surface mount, right angle), and termination method (solder). No PCB or assembly modifications are required. The primary difference is product status (active vs. obsolete) and RoHS compliance.

Q: What is the key difference between the Amphenol and Würth Elektronik substitutes?

A: Amphenol SFW30R-2STE1LF is a direct equivalent from the same manufacturer. Würth Elektronik 68613014122 provides cross-manufacturer compatibility with identical contact configuration but differs in height above board (2.95mm vs. 2.70mm), operating temperature range, and mating cycle rating (25 vs. 20). Both maintain 30-position, 1.00mm pitch, top-contact configuration.

Q: Why is Würth Elektronik 68613014422 listed if it cannot be used as a direct substitute?

A: The 68613014422 is listed as a cross-reference because it shares the same pitch, position count, and mounting style. However, its bottom-contact configuration makes it incompatible with PCBs designed for top-contact connectors. This part is included for reference only and requires PCB redesign for implementation.

Q: Are there any height or clearance concerns when substituting with Würth Elektronik parts?

A: Yes. The Würth Elektronik 68613014122 has a height above board of 2.95mm compared to 2.70mm for the original part. The 68613014422 is 3.00mm. Verify clearance in your PCB assembly before substitution, particularly in space-constrained applications.

Q: What is the operating temperature difference, and does it affect my application?

A: The original SFW30R-2STE1 has no specified operating temperature. SFW30R-2STE1LF operates from -55°C to 105°C, while Würth Elektronik parts operate from -25°C to 85°C. If your application requires operation below -25°C or above 85°C, use the Amphenol SFW30R-2STE1LF.

Q: Are all substitutes RoHS compliant?

A: SFW30R-2STE1 is RoHS non-compliant. SFW30R-2STE1LF is RoHS Compliant. Both Würth Elektronik parts (68613014122 and 68613014422) are ROHS3 Compliant. Verify your application's compliance requirements before selection.

Q: What packaging formats are available for these substitutes?

A: SFW30R-2STE1LF, 68613014122, and 68613014422 are all supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
