Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1135LU-10 is determined by strict equivalence across the following critical parameters:

• Functional Specification: Multiple, non-programmable delay line configuration
• Delay Characteristics: 10ns delay to first tap with 10ns total available delays and 3 independent delay outputs
• Electrical Specifications: 2.7V to 3.6V supply voltage range and -40°C to 85°C operating temperature
• Physical Package: 8-TSSOP/8-MSOP surface mount package with 0.118" (3.00mm) width
• Pin Configuration: 8-pin uMAX/uSOP supplier package

The DS1135LU-10+ meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement in new designs and production environments.

Parameter Comparison

Engineering Selection Recommendations

The DS1135LU-10+ is the direct equivalent for the obsolete DS1135LU-10. Both parts share identical electrical and mechanical specifications, including delay characteristics, supply voltage range, operating temperature, and package configuration. The primary distinction is product status: the DS1135LU-10+ is actively manufactured and supported, whereas the DS1135LU-10 is obsolete.

The DS1135LU-10+ offers improved compliance status with ROHS3 certification, compared to the non-compliant RoHS status of the original part. Both parts maintain REACH Unaffected and EAR99 export classification status. For new designs and production environments requiring long-term component availability and regulatory compliance, the DS1135LU-10+ is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the DS1135LU-10+ be used as a direct replacement for the DS1135LU-10?

A: Yes. The DS1135LU-10+ is electrically and mechanically identical to the DS1135LU-10. All delay characteristics, supply voltage specifications, operating temperature range, and package dimensions are equivalent. Pin configuration and functionality are identical.

Q: What is the primary reason to transition from DS1135LU-10 to DS1135LU-10+?

A: The DS1135LU-10 is classified as obsolete, meaning it is no longer manufactured or supported by Analog Devices Inc./Maxim Integrated. The DS1135LU-10+ is an active product with ongoing manufacturing and availability. Additionally, the DS1135LU-10+ meets ROHS3 compliance requirements, whereas the original part does not.

Q: Are there any differences in package handling or storage requirements?

A: Both parts share identical Moisture Sensitivity Level (MSL) classification of 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage and handling procedures are equivalent.

Q: Will the DS1135LU-10+ function in existing PCB designs without modification?

A: Yes. The DS1135LU-10+ maintains the same 8-TSSOP/8-MSOP package footprint with 0.118" (3.00mm) width. No PCB layout modifications are required for substitution.

Q: Are export classifications affected by this substitution?

A: No. Both the DS1135LU-10 and DS1135LU-10+ carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. Export compliance status remains unchanged.
