Substitute Part Grouping Explanation
Substitution eligibility for the DS90CP04TLQ is determined by strict equivalence across the following critical parameters:
- Crosspoint switch circuit configuration (1 x 4:4)
- Single supply voltage range (2.375V ~ 2.625V)
- Operating temperature range (-40°C ~ 85°C)
- Package specification (32-WQFN with exposed pad)
- Surface mount mounting type
- Regulatory compliance (RoHS3, REACH Unaffected)
- Moisture sensitivity level (MSL 3)
The substitute part DS90CP04TLQ/NOPB meets all electrical and mechanical parameters required for direct substitution. The primary distinction between the main part and substitute is packaging format: the main part is supplied in Cut Tape (CT) & Digi-Reel format, while the substitute is supplied in Tape & Reel (TR) format. Both parts share the identical base product number DS90CP04 and are manufactured by Texas Instruments.

Engineering Selection Recommendations
The DS90CP04TLQ/NOPB is the direct functional equivalent for the DS90CP04TLQ. Both parts are manufactured by Texas Instruments and share identical electrical specifications, package geometry, and regulatory compliance certifications. The substitute part carries Active product status, ensuring continued availability and manufacturing support, whereas the main part is designated Last Time Buy. For new designs or ongoing production requiring long-term component availability, the DS90CP04TLQ/NOPB is the appropriate selection. The packaging format difference (Tape & Reel versus Cut Tape) does not affect electrical performance or mechanical compatibility on the PCB; this distinction is relevant only to procurement and handling procedures.
Frequently Asked Questions (FAQ)
Q: Can DS90CP04TLQ/NOPB be used as a direct replacement for DS90CP04TLQ?
A: Yes. Both parts are electrically and mechanically identical. They share the same base product number, circuit configuration, voltage supply range, operating temperature range, package specification, and regulatory compliance status. The only difference is packaging format and product lifecycle status.
Q: What is the significance of the "/NOPB" suffix in DS90CP04TLQ/NOPB?
A: The "/NOPB" suffix indicates the part is supplied in Tape & Reel (TR) packaging format without lead-free plating on the leads. This is a standard Texas Instruments designation for high-volume production packaging.
Q: Are there any compatibility concerns when substituting DS90CP04TLQ with DS90CP04TLQ/NOPB?
A: No compatibility concerns exist. The parts are pin-compatible, have identical electrical characteristics, and are housed in the same 32-WQFN (6x6) package with exposed pad. PCB layout and design requirements remain unchanged.
Q: Why is the main part DS90CP04TLQ listed as Last Time Buy?
A: Last Time Buy status indicates Texas Instruments is discontinuing this specific packaging configuration. The DS90CP04TLQ/NOPB remains in Active status and represents the current production equivalent.
Q: Does the Moisture Sensitivity Level (MSL 3) apply to both parts?
A: Yes. Both DS90CP04TLQ and DS90CP04TLQ/NOPB have MSL 3 rating with a floor life of 168 hours. Identical moisture handling and storage procedures apply to both parts.
Q: Are both parts RoHS3 compliant?
A: Yes. Both DS90CP04TLQ and DS90CP04TLQ/NOPB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
