Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 1541150-1 is based on electrical and mechanical compatibility within the following parameters:

Critical Matching Parameters:

• Circuit configuration: SPST
• Switch function: On-Off
• AC current rating: 20A minimum
• AC voltage rating: 125V
• Mounting type: Panel Mount, Snap-In
• Termination style: Quick Connect - 0.250" (6.3mm)

Allowable Variations:

• Actuator type and color (mechanical interface differences)
• Actuator marking appearance
• Panel cutout dimensions (within mechanical tolerance for snap-in installation)
• Additional electrical ratings (DC current, DC voltage) when AC specifications are met
• Ingress protection rating (enhanced environmental protection)
• Operating temperature range (extended operational envelope)
• Mechanical and electrical life cycles (performance metrics)
• Product status (active alternatives preferred for obsolete parts)

The substitute part KTG2ANB1BBDNNN from ZF Electronics meets all critical electrical parameters and maintains mechanical compatibility through identical termination and mounting standards.

Parameter Comparison

Engineering Selection Recommendations

The ZF Electronics KTG2ANB1BBDNNN is a direct functional substitute for the obsolete TE Connectivity 1541150-1 based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical AC electrical specifications (20A at 125V), satisfying the core functional requirement. The substitute provides additional DC ratings (21A at 14V), extending application flexibility without compromising AC performance.

Mechanical Compatibility: Both switches employ identical quick connect 0.250" (6.3mm) termination and panel mount snap-in installation methods. Panel cutout dimensions are nearly identical (36.83mm vs. 36.80mm width; 21.08mm vs. 15.20mm height), with the substitute featuring a narrower height dimension that accommodates the original cutout specification.

Product Status and Compliance: The substitute part is active in production, ensuring long-term availability and supply chain stability. The KTG2ANB1BBDNNN carries ROHS3 compliance certification, meeting current environmental regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications.

Enhanced Performance Characteristics: The substitute provides specified operating temperature range (-20°C ~ 85°C), mechanical life (100,000 cycles), and electrical life (6,000 cycles), along with IP56 ingress protection. These specifications represent performance enhancements over the original part.

Actuator Differences: The substitute features a convex (reverse V) black actuator in place of the original red paddle. This represents a mechanical interface change that does not affect electrical function or panel mount compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ZF Electronics KTG2ANB1BBDNNN directly replace the TE Connectivity 1541150-1 in existing applications?

A: Yes. Both switches meet identical AC electrical specifications (20A at 125V) and employ the same quick connect 0.250" (6.3mm) termination and panel mount snap-in installation method. The substitute is electrically and mechanically compatible for direct replacement.

Q: What is the significance of the panel cutout dimension difference (21.08mm vs. 15.20mm height)?

A: The substitute part has a narrower height dimension. Existing panel cutouts sized for the original 36.83mm x 21.08mm specification will accommodate the substitute's 36.80mm x 15.20mm dimension. The narrower height provides additional clearance and does not create installation conflicts.

Q: Does the change from a red paddle actuator to a black convex actuator affect functionality?

A: No. The actuator type and color are mechanical interface characteristics that do not affect electrical performance or switching function. Both actuators provide On-Off control through identical SPST circuit configuration.

Q: What compliance advantages does the substitute part provide?

A: The ZF Electronics KTG2ANB1BBDNNN carries ROHS3 compliance certification, meeting current environmental regulatory standards. Both parts share identical export classification (EAR99) and tariff codes (8536.50.9065).

Q: Are there any electrical performance differences between the two parts?

A: The substitute provides additional DC electrical ratings (21A at 14V) beyond the AC specification (20A at 125V). For AC-only applications, both parts deliver identical performance. The substitute's additional DC capability expands application flexibility without affecting AC operation.

Q: What is the inventory status for each part?

A: The original TE Connectivity 1541150-1 is obsolete with 892 pieces in stock. The ZF Electronics KTG2ANB1BBDNNN is active in production with 1,123 pieces in stock, providing superior long-term availability.

Q: Does the substitute part offer environmental protection advantages?

A: Yes. The KTG2ANB1BBDNNN carries IP56 ingress protection rating (dust protected, water resistant), providing enhanced environmental protection compared to the original part specification.
