Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1571095-6 is determined by strict alignment of the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPST (Single Pole Single Throw)
• AC current rating must support minimum 20A at 125V
• Switch function must be On-Off type

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Snap-In
• Panel cutout dimensions must be Rectangular 36.60mm x 21.20mm
• Actuator type must be Concave (Curved)
• Actuator color must be Black

Environmental & Lifecycle Requirements:

• Operating temperature range must encompass -20°C to 85°C
• Mechanical life must be minimum 100,000 cycles
• Electrical life must be minimum 6,000 cycles
• Ingress protection must be IP56 or higher

Regulatory Compliance:

• RoHS compliance status must be current (RoHS Compliant or ROHS3 Compliant)

The ZF Electronics KGC2ANB1BBD meets all critical electrical, mechanical, and environmental parameters. Termination style differs (Quick Connect vs. Solder Lug), requiring evaluation based on circuit board design and assembly process compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ZF Electronics KGC2ANB1BBD is a qualified substitute for the obsolete TE Connectivity ALCOSWITCH 1571095-6 based on the following engineering criteria:

Electrical Performance Alignment: The substitute part maintains identical AC current rating (20A) and voltage rating (125V) with SPST circuit configuration. The substitute additionally supports 21A DC at 14V, providing extended capability for DC applications.

Mechanical Compatibility: Panel mount snap-in installation, panel cutout dimensions, actuator type, and actuator color are identical. Physical installation into existing panel designs is directly compatible.

Environmental Performance: Operating temperature range, mechanical life cycle rating, and electrical life cycle rating are identical. The substitute provides IP56 ingress protection, which is lower than the original IP66 rating but remains suitable for dust-protected and water-resistant applications.

Regulatory Compliance: The substitute part holds ROHS3 Compliant status, representing current regulatory compliance. The original part is RoHS Compliant. Both meet environmental regulatory requirements.

Product Availability: The substitute part is classified as Active status with 3183 pieces in stock, ensuring supply continuity for applications requiring this switch type.

Termination Consideration: The primary difference is termination style. The original uses Solder Lug termination; the substitute uses Quick Connect 0.250" (6.3mm) termination. Circuit board design and assembly process compatibility must be evaluated based on specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the ZF Electronics KGC2ANB1BBD directly replace the TE Connectivity 1571095-6 in existing applications?

A: Electrical and mechanical compatibility is direct for panel mount applications with identical cutout dimensions. Termination style differs (Quick Connect vs. Solder Lug), requiring circuit board design compatibility assessment. Ingress protection is IP56 versus IP66; applications requiring IP66 dust-tight specifications must evaluate environmental exposure conditions.

Q: What is the significance of the different ingress protection ratings?

A: The original part is rated IP66 (dust tight, water resistant to high-pressure jets). The substitute is rated IP56 (dust protected, water resistant to splashing). IP56 is suitable for most industrial panel mount applications but may not meet specifications for high-pressure wash environments or sealed enclosures requiring complete dust exclusion.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts require a rectangular panel cutout of 36.60mm x 21.20mm. Existing panel designs require no modification for physical installation.

Q: What is the difference in actuator marking?

A: The original part has actuator marking "O I" (Off-On). The substitute has actuator marking "O -" (Off-On with dash). Both indicate the same On-Off switch function; marking presentation differs visually.

Q: Does the substitute support DC applications?

A: Yes. The substitute part is rated for 21A DC at 14V, whereas the original part specification lists only AC ratings. This provides additional capability for DC circuit applications.

Q: What is the impact of different termination styles on assembly?

A: Solder Lug termination requires wave soldering or hand soldering to circuit board pads. Quick Connect 0.250" (6.3mm) termination uses push-on connectors. Assembly process, connector availability, and circuit board pad design determine compatibility. Existing designs using solder lug termination require connector adaptation or board redesign for quick connect substitution.

Q: Are both parts RoHS compliant?

A: Yes. The original part is RoHS Compliant. The substitute part is ROHS3 Compliant, representing current regulatory compliance standards. Both meet environmental regulatory requirements for restricted substance elimination.

Q: What is the product status significance?

A: The original TE Connectivity part is classified as Obsolete, indicating discontinued manufacturing and limited availability. The substitute ZF Electronics part is classified as Active with current production and 3183 pieces in stock, ensuring supply continuity for new designs and ongoing maintenance applications.
