Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1135LU-30 is determined by strict equivalence across the following critical parameters:

• Delay to 1st Tap: 30ns
• Available Total Delays: 30ns
• Number of Independent Delays: 3
• Voltage - Supply: 2.7V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
• Mounting Type: Surface Mount
• Function: Multiple, NonProgrammable

Parts meeting all these parameters are classified as direct substitutes. Deviations in any parameter disqualify a component from substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

The DS1135LU-30+ is a direct functional equivalent to the DS1135LU-30. Both components share identical electrical specifications, delay characteristics, and physical packaging. The primary distinction is product lifecycle status: the DS1135LU-30 is obsolete, while the DS1135LU-30+ maintains active production status.

The DS1135LU-30+ additionally provides ROHS3 compliance, whereas the original part is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic component manufacturing and procurement.

Selection of the DS1135LU-30+ is appropriate for new designs and replacement applications where supply chain continuity is required.

Frequently Asked Questions (FAQ)

Q: Are the DS1135LU-30 and DS1135LU-30+ electrically interchangeable?

A: Yes. Both components feature identical delay specifications (30ns), supply voltage range (2.7V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and functional characteristics (multiple, non-programmable taps with 3 independent delays).

Q: Can the DS1135LU-30+ be used as a direct replacement in existing designs?

A: Yes. The DS1135LU-30+ is housed in the same 8-TSSOP/8-MSOP package with identical pinout and electrical performance. No circuit modifications are required.

Q: What is the significance of the product status difference?

A: The DS1135LU-30 is classified as obsolete, indicating discontinued production. The DS1135LU-30+ is active, ensuring ongoing availability and supply chain support.

Q: Does the RoHS3 compliance of the DS1135LU-30+ affect compatibility?

A: No. RoHS3 compliance indicates adherence to hazardous substance restrictions and does not alter electrical or mechanical compatibility. This represents an improvement in regulatory alignment.

Q: Are there any package or pinout differences between these parts?

A: No. Both components use the 8-TSSOP/8-MSOP package with 0.118" width (3.00mm). Pinout and physical dimensions are identical.
