• Bushing thread specification (Unthreaded)

Environmental & Operational Compatibility:

• Ingress protection rating (IP67)
• Operating temperature range (-30°C to 85°C)
• Process sealed construction
• Electrical life (6,000 cycles)

Regulatory & Compliance Compatibility:

• RoHS3 compliance
• REACH affected status
• ECCN classification (EAR99)

The substitute part 1825142-2 maintains all mechanical and environmental specifications while providing enhanced electrical ratings. This part is from the same Gemini AE series and shares identical physical form factors and mounting characteristics, ensuring direct mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH 1825142-2 is the direct substitute for the obsolete 1825142-1. Both parts are manufactured by TE Connectivity within the Gemini AE series and share identical mechanical, environmental, and regulatory characteristics.

Product Status Consideration: The 1825142-1 is classified as obsolete, while the 1825142-2 maintains active product status with confirmed inventory availability (1014 pieces in stock). This status difference ensures long-term supply chain reliability and continued manufacturer support for the substitute part.

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH affected status, ensuring regulatory alignment for applications requiring these certifications. The ECCN classification (EAR99) remains consistent across both parts.

Electrical Rating Differences: The substitute part 1825142-2 provides enhanced electrical ratings (5A at 120V AC / 28V DC) compared to the original part (0.4VA at 20V AC/DC). This upgrade in electrical capacity ensures the substitute part operates safely in applications originally designed for the 1825142-1, as the substitute accommodates higher power requirements without compromising performance in lower-power applications.

Mechanical Interchangeability: Identical mounting configuration, actuator specifications, and termination style ensure direct mechanical replacement without requiring PCB layout modifications or mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can the 1825142-2 be used as a direct replacement for the 1825142-1 in existing designs?

A: Yes. The 1825142-2 is mechanically and functionally compatible with the 1825142-1. Both parts share identical mounting type (through-hole, right-angle), actuator specifications (standard round, 7.62mm length), termination style (PC pin), and circuit configuration (SPDT, On-On). The substitute part can be installed without PCB modifications.

Q: What are the key differences between these two parts?

A: The primary differences are product status and electrical ratings. The 1825142-1 is obsolete with 0.4VA at 20V ratings, while the 1825142-2 is active with enhanced ratings of 5A at 120V AC and 28V DC. Both parts maintain identical mechanical form factors, environmental protection (IP67), operating temperature range (-30°C to 85°C), and regulatory compliance (ROHS3, REACH affected).

Q: Are there any compatibility concerns when substituting the 1825142-2 for the 1825142-1?

A: No compatibility concerns exist for mechanical or environmental aspects. The higher electrical ratings of the 1825142-2 ensure safe operation in applications originally specified for the lower-rated 1825142-1. Applications requiring the full 5A capacity of the substitute part will benefit from the enhanced electrical performance.

Q: What is the packaging difference between these parts?

A: The 1825142-1 is supplied with unspecified packaging, while the 1825142-2 is supplied in bulk packaging. This difference affects order quantities and handling procedures but does not impact electrical or mechanical performance.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 1825142-1 and 1825142-2 are ROHS3 compliant and REACH affected, meeting current regulatory requirements for electronic components in applicable markets.

Q: What is the electrical life specification for these switches?

A: Both parts are rated for 6,000 electrical cycles, providing equivalent operational longevity under normal switching conditions.

Q: Can the 1825142-2 be used in applications with voltage requirements below 20V?

A: Yes. The 1825142-2 is rated for 120V AC and 28V DC, which encompasses the original part's 20V specification. The substitute part operates safely at lower voltages within its rated range.
