LC241 Solid State Relay SPST-NO 1.5A 12-280V Equivalent & Substitute Parts

Part Overview

The LC241 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (Single Pole Single Throw, Normally Open) device with 1 Form A circuit topology. This component is rated for 1.5A load current across a 12V to 280V AC output range, with a 4-10VDC input control voltage. The LC241 operates with zero-cross switching for AC loads and is packaged in a 4-SIP (Single In-line Package) through-hole format.

The LC241 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for repair, maintenance, and new production applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LC241 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology must be maintained
• Output Type: AC operation with zero-cross switching capability
• Input Voltage Range: 4 ~ 10VDC control voltage
• Load Voltage Range: 12 V ~ 280 V AC
• Load Current Rating: 1.5 A minimum
• Package Format: 4-SIP through-hole configuration
• Termination: PC Pin connectivity

The ASO241 meets all these criteria and is classified as a direct manufacturer equivalent from Sensata-Crydom. The ASO241 maintains identical electrical specifications and mechanical form factor, with the distinction that it is currently in active production status and carries updated compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ASO241 is the direct equivalent substitute for the LC241. Both components are manufactured by Sensata-Crydom and share identical electrical ratings and mechanical specifications. The ASO241 is currently in active production, ensuring long-term availability and supply chain continuity.

The ASO241 carries ROHS3 compliance certification, indicating adherence to current environmental and material restriction standards. The REACH Affected status reflects updated regulatory compliance documentation applicable to current manufacturing and distribution.

For applications requiring the LC241, the ASO241 provides functional and form-factor equivalence with the added benefit of active product status and current compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the ASO241 be used as a direct replacement for the LC241?

A: Yes. The ASO241 is electrically and mechanically equivalent to the LC241. Both components feature identical SPST-NO circuit configuration, 1.5A load current rating, 4-10VDC input voltage, 12-280V AC load voltage range, and 4-SIP through-hole package format. Direct substitution is supported without circuit modification.

Q: What is the primary difference between the LC241 and ASO241?

A: The LC241 is obsolete, while the ASO241 is in active production. The ASO241 carries ROHS3 compliance and updated REACH documentation. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both the LC241 and ASO241 use the 4-SIP package format with PC Pin termination. Pinout and mechanical dimensions are identical, enabling direct board-level substitution.

Q: What compliance certifications apply to the ASO241?

A: The ASO241 is ROHS3 compliant and REACH affected. These certifications reflect current environmental and material restriction standards for electronic components.

Q: Is the ASO241 suitable for new product designs?

A: Yes. The ASO241 is in active production status and carries current compliance certifications, making it appropriate for new designs requiring SPST-NO solid state relay functionality in the specified voltage and current range.
