Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASR-SI240D10R is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Circuit configuration: SPST-NO (1 Form A)
• Input voltage range: 4 ~ 32VDC
• Load voltage range: 48 V ~ 280 V
• Load current rating: 10 A
• Output type: AC

Mechanical and Physical Specifications:

• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package form factor: Hockey Puck

Compliance and Regulatory:

• RoHS3 Compliance
• REACH Unaffected status

Substitute parts must match all electrical parameters, physical form factor, and regulatory compliance status to ensure direct functional replacement without circuit modification or re-qualification.

Parameter Comparison

Engineering Selection Recommendations

The ASR-SI240D10R-LR is the direct equivalent substitute for the obsolete ASR-SI240D10R. Both components are manufactured by Altran Magnetics, LLC and share identical electrical specifications, mechanical form factor, and regulatory compliance certifications.

The primary distinction is product status: the ASR-SI240D10R-LR maintains active production status, ensuring availability for procurement and supply chain continuity. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component deployment.

Selection of the ASR-SI240D10R-LR eliminates obsolescence risk while maintaining full functional and physical compatibility with existing circuit designs and mechanical installations.

Frequently Asked Questions (FAQ)

Q: Can the ASR-SI240D10R-LR be used as a direct replacement for the ASR-SI240D10R?

A: Yes. The ASR-SI240D10R-LR is electrically and mechanically identical to the ASR-SI240D10R across all specified parameters, including input voltage range (4 ~ 32VDC), load voltage range (48 V ~ 280 V), load current rating (10A), circuit configuration (SPST-NO), and package form factor (hockey puck with screw terminals). No circuit modification or mechanical re-design is required.

Q: What is the primary reason to transition from ASR-SI240D10R to ASR-SI240D10R-LR?

A: The ASR-SI240D10R is classified as obsolete, creating supply chain risk. The ASR-SI240D10R-LR is the active production equivalent, ensuring long-term availability and procurement reliability.

Q: Are there any compliance differences between these two parts?

A: No. Both the ASR-SI240D10R and ASR-SI240D10R-LR are ROHS3 compliant and REACH unaffected. Regulatory compliance status is identical.

Q: Does the hockey puck package form factor remain the same?

A: Yes. Both parts use the hockey puck package with chassis mount configuration and screw terminal termination. Physical installation and PCB layout compatibility are maintained.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching input voltage range (4 ~ 32VDC), load voltage range (48 V ~ 280 V), load current rating (10A), circuit configuration (SPST-NO 1 Form A), and output type (AC). The ASR-SI240D10R-LR meets all these criteria.
