Engineering Selection Recommendations

For new designs and ongoing production, DS1086LU-21D+, DS1086LU-222+, DS1086LU-527+, and DS1086LU-533+ are preferred substitutes as they maintain Active product status. These parts carry identical electrical and mechanical specifications to the DS1086LU-8CL+ while offering continued manufacturer support and supply chain availability.

DS1086LU-A12+ is also parametrically equivalent but shares Obsolete status with the original part. Selection of this substitute does not improve long-term availability.

All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions. Surface mount packaging and 8-uMAX/uSOP footprint remain consistent across all alternatives, enabling direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can DS1086LU-21D+, DS1086LU-222+, DS1086LU-527+, or DS1086LU-533+ be used as direct replacements for DS1086LU-8CL+?

A: Yes. All four parts are parametrically equivalent across electrical specifications, package dimensions, pin configuration, supply voltage range, operating temperature range, and compliance certifications. Direct substitution is valid for applications where the DS1086LU-8CL+ was originally specified.

Q: What is the difference between the substitute part numbers?

A: The suffix designations (21D, 222, 527, 533, A12) indicate different frequency programming or configuration options within the same device family. All variants share identical package, electrical operating range, and compliance characteristics. Frequency selection should be verified against application requirements.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use the 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) package with 8-uMAX/uSOP supplier device package designation. Packaging format is consistent across all alternatives. Tube and Bulk packaging options are available depending on part number selection.

Q: Is the DS1086LU-8CL+ still in production?

A: No. The DS1086LU-8CL+ is classified as Obsolete. Active alternatives (DS1086LU-21D+, DS1086LU-222+, DS1086LU-527+, DS1086LU-533+) are recommended for new designs and ongoing production to ensure supply chain continuity.

Q: Do all substitute parts meet RoHS and MSL requirements?

A: Yes. All substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original part's compliance profile. These certifications ensure compatibility with standard manufacturing processes and storage conditions.
