Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ASR-SD480D5ZL is based on strict alignment of the following critical parameters:

Mandatory Matching Criteria:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC with zero-cross switching
• Load current rating: 5 A
• Package type: 4-SIP
• Mounting type: Through hole
• Termination style: PC pin
• Manufacturer series: SD (Altran Magnetics, LLC)
• Regulatory compliance: ROHS3 compliant

Allowable Parameter Variations: Substitute parts may differ in input voltage range and load voltage range specifications, provided the substitute part's operating ranges encompass or are compatible with the application requirements. Product status transition from obsolete to active is acceptable for substitution purposes.

The ASR-SD480D5ZW qualifies as a direct substitute based on identical circuit topology, output characteristics, current rating, package configuration, and mounting specifications.

Parameter Comparison

Engineering Selection Recommendations

The ASR-SD480D5ZW is designated as the manufacturer-recommended substitute for the obsolete ASR-SD480D5ZL. Both components maintain identical electrical circuit topology, switching characteristics, current capacity, and physical package specifications required for direct substitution in through-hole PCB applications.

The substitute part offers extended input voltage tolerance (4 ~ 32 VDC versus 4 ~ 15 VDC), providing enhanced operational flexibility in applications with variable input supply conditions. The ASR-SD480D5ZW carries active product status, ensuring continued availability and manufacturing support.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component procurement. The transition from not applicable to MSL 1 (unlimited) moisture sensitivity classification on the substitute part indicates improved environmental stability characteristics.

Selection of the ASR-SD480D5ZW is appropriate for new designs and replacement applications where the original ASR-SD480D5ZL is no longer available through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the ASR-SD480D5ZW directly replace the ASR-SD480D5ZL in existing circuit designs?

A: Yes. Both components share identical SPST-NO circuit configuration, 5A load current rating, AC zero-cross output type, 4-SIP package geometry, through-hole mounting, and PC pin termination. Direct substitution is supported without circuit modification.

Q: What is the significance of the input voltage range difference between these parts?

A: The ASR-SD480D5ZL operates with input voltage from 4 ~ 15 VDC, while the ASR-SD480D5ZW extends this range to 4 ~ 32 VDC. Applications requiring input voltages within the 4 ~ 15 VDC window are compatible with both parts. Applications utilizing input voltages between 15 ~ 32 VDC require the ASR-SD480D5ZW.

Q: Why does the load voltage range differ between the two parts?

A: The ASR-SD480D5ZL supports load voltages from 24 V to 530 V, while the ASR-SD480D5ZW is specified for 24 V load voltage only. Applications requiring load voltages exceeding 24 V must retain the original ASR-SD480D5ZL or identify alternative components with extended load voltage ratings.

Q: Are both parts suitable for new product designs?

A: The ASR-SD480D5ZL is classified as obsolete and should not be selected for new designs. The ASR-SD480D5ZW carries active product status and is the appropriate choice for new development projects.

Q: What does the MSL rating change from "Not Applicable" to "1 (Unlimited)" indicate?

A: MSL 1 (Unlimited) classification on the ASR-SD480D5ZW indicates the component has no moisture sensitivity restrictions and does not require special handling, storage, or baking procedures prior to soldering. This represents an improvement in manufacturing robustness compared to the original part specification.

Q: Are the 4-SIP packages physically identical between both parts?

A: Yes. Both the ASR-SD480D5ZL and ASR-SD480D5ZW utilize identical 4-SIP package geometry with PC pin termination, ensuring mechanical compatibility with existing through-hole PCB layouts without modification.
