Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-487951-6 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• 16-position connector configuration
• 1.00mm (0.039") pitch spacing
• Surface mount, right-angle orientation
• Top-contact configuration
• Solder termination method
• 0.30mm FFC/FCB thickness compatibility
• Slide lock retention mechanism
• Zero insertion force (ZIF) operation
• UL94 V-0 flammability rating
• 1A current rating
• Phosphor bronze contact material

Substitute Parts Identified:

1. TE Connectivity 1-84953-6 (Direct Equivalent): Active product with identical electrical and mechanical specifications. Primary difference is contact finish thickness (78.7µin vs. 150.0µin) and RoHS3 compliance status.

2. Amphenol ICC SFW16R-4STE1LF (Functional Equivalent): Meets all critical substitution parameters with allowable variations in housing material (PPS vs. LCP), height above board (2.70mm vs. 2.56mm), and cable end type (notched/tapered vs. straight).

Engineering Selection Recommendations

TE Connectivity 1-84953-6 (Direct Equivalent - Recommended Primary Substitute)

The 1-84953-6 is the direct equivalent replacement for the obsolete 1-487951-6. Both parts share identical electrical and mechanical specifications across all critical parameters: 16-position configuration, 1.00mm pitch, surface mount right-angle orientation, 0.30mm FFC thickness, and 2.56mm height above board. The primary distinction is product status: 1-84953-6 is active with 3494 units in stock, compared to the obsolete status of 1-487951-6.

Compliance differences include RoHS3 compliance status (1-84953-6 is compliant; 1-487951-6 is non-compliant) and contact finish thickness reduction (78.7µin vs. 150.0µin). These differences do not affect functional compatibility. The 1-84953-6 is suitable for direct substitution in new designs and production transitions.

Amphenol ICC SFW16R-4STE1LF (Functional Equivalent - Secondary Substitute)

The SFW16R-4STE1LF provides functional equivalence with allowable parameter variations. This part maintains the 16-position, 1.00mm pitch, surface mount right-angle configuration with identical contact material, termination method, and ZIF/solder retention features. Differences include:

• Housing material: PPS (glass filled) instead of LCP (glass filled)
• Height above board: 2.70mm instead of 2.56mm (0.14mm variation)
• Cable end type: Notched/tapered instead of straight
• Voltage rating: 100V instead of 200V
• Operating temperature range: -55°C ~ 105°C instead of -40°C ~ 85°C
• Mating cycles: 20 specified (not provided for main part)

The SFW16R-4STE1LF is RoHS compliant and REACH affected. This part is suitable for applications where the voltage rating of 100V is sufficient and the extended temperature range provides operational advantage. The 0.14mm height variation and alternative cable end type require mechanical design verification.

Frequently Asked Questions (FAQ)

Q: Can the 1-84953-6 be used as a direct replacement for the 1-487951-6 without design modifications?

A: Yes. The 1-84953-6 is a direct equivalent with identical electrical and mechanical specifications. No design modifications are required. The contact finish thickness reduction and RoHS3 compliance represent improvements for modern manufacturing standards.

Q: What are the key differences between the TE Connectivity 1-84953-6 and the Amphenol ICC SFW16R-4STE1LF?

A: Both parts share the same 16-position, 1.00mm pitch, surface mount right-angle configuration. Primary differences are: housing material (PPS vs. LCP), height above board (2.70mm vs. 2.56mm), cable end type (notched/tapered vs. straight), voltage rating (100V vs. 200V), and operating temperature range (-55°C ~ 105°C vs. -40°C ~ 85°C). The SFW16R-4STE1LF is suitable for applications where these variations are acceptable.

Q: Is the 0.14mm height difference between the 1-84953-6 and SFW16R-4STE1LF significant?

A: The 0.14mm height variation (2.56mm vs. 2.70mm) must be evaluated against specific PCB layout and mechanical clearance requirements. Applications with tight vertical constraints may require design verification before substitution.

Q: What is the impact of the voltage rating difference (200V vs. 100V) between the main part and the Amphenol substitute?

A: The 1-487951-6 and 1-84953-6 are rated for 200V, while the SFW16R-4STE1LF is rated for 100V. For applications operating at voltages above 100V, the SFW16R-4STE1LF is not suitable. For applications operating at 100V or below, the lower voltage rating does not restrict functionality.

Q: Are there RoHS compliance considerations for these substitutes?

A: The original 1-487951-6 is RoHS non-compliant. The 1-84953-6 is ROHS3 compliant, and the SFW16R-4STE1LF is RoHS compliant. For applications requiring RoHS compliance, both substitute parts are acceptable. The 1-84953-6 is the preferred choice for RoHS3 compliance requirements.

Q: What packaging formats are available for these parts?

A: The 1-84953-6 is supplied in Cut Tape (CT) packaging. The SFW16R-4STE1LF is supplied in Tape & Reel (TR) packaging. Packaging selection depends on production volume and assembly process requirements.

Q: Can the cable end type difference (straight vs. notched/tapered) affect compatibility?

A: The cable end type affects the physical interface with the flexible circuit board. The 1-487951-6 and 1-84953-6 use straight cable ends, while the SFW16R-4STE1LF uses notched/tapered ends. Substitution requires verification that the flexible circuit board design accommodates the alternative cable end geometry.

Q: What is the MSL (Moisture Sensitivity Level) rating for these connectors?

A: All three parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.
