Engineering Selection Recommendations
MP4088GS-Z (Monolithic Power Systems Inc.) is the primary substitute for the CS1613A-FSZR. This part maintains Triac dimming capability, single output configuration, and identical operating temperature range (-40°C to 125°C). The MP4088GS-Z is active status with ROHS3 compliance and superior moisture sensitivity (MSL 2 vs. MSL 3). Package configuration is 8-SOIC with 7 leads, requiring PCB layout verification.
MP4060GS-Z (Monolithic Power Systems Inc.) provides an alternative with Triac dimming and buck-boost topology. Operating temperature range matches the original part. This part is active status with ROHS3 compliance and MSL 2 rating. Supply voltage range is 200VAC to 265VAC, suitable for AC line-powered applications.
LYT1603D-TL (Power Integrations) offers active status with RoHS compliance and unlimited moisture sensitivity (MSL 1). This part features internal switching capability and operates across -40°C to 125°C. Supply voltage range is 90VAC to 308VAC. Note that dimming specification is not provided for this part.
AL9910A-5S-13 (Diodes Incorporated) provides active status with unlimited moisture sensitivity. This part supports both analog and PWM dimming modes. Operating temperature range is -40°C to 85°C, which is lower than the original part. Supply voltage range is 20V to 500V.
NCL30186DDR2G (onsemi) is active status with ROHS3 compliance and unlimited moisture sensitivity. This part supports multiple topologies (Flyback, SEPIC, Buck, Boost) and both analog and PWM dimming. Operating temperature range is -40°C to 125°C. Supply voltage range is 8.8V to 25.5V.
Selection should prioritize active status parts with MSL 1 or MSL 2 ratings for improved supply chain reliability. Package footprint differences require PCB design verification before implementation.
Frequently Asked Questions (FAQ)
Q: Can MP4088GS-Z directly replace CS1613A-FSZR on existing PCBs?
A: Package footprint verification is required. The CS1613A-FSZR uses 16-SOIC packaging while MP4088GS-Z uses 8-SOIC with 7 leads. Pin configuration and lead count differences necessitate PCB layout review and potential redesign.
Q: What is the primary reason to substitute the CS1613A-FSZR?
A: The CS1613A-FSZR is classified as obsolete. Active substitute parts ensure long-term availability, improved supply chain reliability, and access to current manufacturing processes with enhanced compliance certifications.
Q: Which substitute parts maintain Triac dimming capability?
A: MP4088GS-Z and MP4060GS-Z both support Triac dimming, matching the original CS1613A-FSZR functionality. AL9910A-5S-13 and NCL30186DDR2G support analog and PWM dimming as alternatives.
Q: Are all substitute parts RoHS compliant?
A: MP4088GS-Z, MP4060GS-Z, and NCL30186DDR2G are ROHS3 compliant. LYT1603D-TL is RoHS compliant. AL9910A-5S-13 RoHS status is not specified in the provided data.
Q: What is the significance of Moisture Sensitivity Level (MSL) differences?
A: The CS1613A-FSZR has MSL 3 (168 hours), requiring controlled storage conditions. Substitute parts with MSL 1 (unlimited) or MSL 2 (1 year) offer improved handling flexibility and reduced risk of moisture-related failures during storage and assembly.
Q: Which substitute part has the widest supply voltage range?
A: AL9910A-5S-13 supports 20V to 500V supply range, providing maximum flexibility for diverse power supply architectures. MP4060GS-Z operates at 200VAC to 265VAC for AC line applications.
Q: Do all substitute parts support the same operating temperature range?
A: Most substitute parts support -40°C to 125°C. AL9910A-5S-13 operates at -40°C to 85°C, which is more limited. Verify temperature requirements for your specific application before selection.
