Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASR-SD480D5RL is determined by the following critical electrical and mechanical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: SPST-NO (1 Form A)
• Output Type: AC
• Load Current Rating: 5 A
• Package / Case: 4-SIP
• Termination Style: PC Pin
• Mounting Type: Through Hole

Voltage Compatibility Considerations: The ASR-SD480D5RL operates with input voltage of 4 ~ 15VDC and load voltage of 24 V ~ 530 V. Substitute parts must maintain compatibility with the intended application's voltage requirements. The input voltage range and load voltage range are critical parameters that determine functional equivalence in specific circuit applications.

Compliance and Status: Active product status and ROHS3 compliance are preferred for new designs and long-term availability. Obsolete parts require substitution to ensure supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The ASR-SD480D5RW is the manufacturer-recommended substitute for the obsolete ASR-SD480D5RL. Both components share identical circuit configuration (SPST-NO), output type (AC), load current rating (5A), package format (4-SIP), and termination style (PC Pin). Both parts maintain ROHS3 compliance and are manufactured by Altran Magnetics, LLC within the SD series.

The ASR-SD480D5RW offers active product status, ensuring availability for procurement and long-term supply chain support. The substitute part extends the input voltage range to 4 ~ 32VDC, providing broader input compatibility compared to the original 4 ~ 15VDC specification.

Application-specific load voltage requirements must be evaluated. The original part supports load voltages from 24V to 530V, while the substitute part is rated for 24V load voltage only. Selection between these parts depends on whether the application requires the extended load voltage range of the original component or operates within the 24V load voltage specification of the substitute.

Frequently Asked Questions (FAQ)

Q: Can the ASR-SD480D5RW directly replace the ASR-SD480D5RL in all applications?

A: Direct replacement is possible when the application load voltage requirement is 24V. If the original application requires load voltages exceeding 24V up to 530V, the ASR-SD480D5RW is not suitable. Circuit design review is necessary to confirm load voltage compatibility.

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

A: The primary differences are product status (obsolete vs. active), input voltage range (4~15VDC vs. 4~32VDC), and load voltage range (24~530V vs. 24V only). All other electrical and mechanical parameters remain identical.

Q: Are both parts physically compatible with existing PCB designs?

A: Yes. Both parts use identical 4-SIP package format with PC Pin termination and Through Hole mounting type. Physical PCB layout compatibility is maintained.

Q: Why does the substitute part have a narrower load voltage range?

A: Load voltage range is determined by the internal semiconductor design and thermal characteristics of the solid state relay. The ASR-SD480D5RW is optimized for 24V load applications, while the original ASR-SD480D5RL was designed for extended voltage range operation.

Q: Is the expanded input voltage range of the substitute part beneficial?

A: The ASR-SD480D5RW input voltage range of 4~32VDC provides greater flexibility for control circuit designs compared to the original 4~15VDC range. This allows operation with higher input voltage sources without additional regulation.

Q: What compliance certifications apply to both parts?

A: Both the ASR-SD480D5RL and ASR-SD480D5RW are ROHS3 compliant and REACH unaffected. Both carry ECCN classification EAR99 and HTSUS code 8536.41.0030.
