Key Parameters

Substitute Part Grouping Explanation

Substitution suitability is determined by matching the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Isolation: 5000Vrms (mandatory)
• Common Mode Transient Immunity (Min): 15kV/µs (mandatory)
• Input Type: DC (mandatory)
• Output Type: Open Collector (mandatory)
• Number of Channels: 1 (mandatory)
• Mounting Type: Through Hole, 8-DIP package (mandatory)
• RoHS Status: RoHS3 Compliant (mandatory)

Secondary Performance Criteria (must be equal or exceed):

• Current - Output / Channel: 25 mA (or higher)
• Data Rate: 10Mbps (or higher)
• Operating Temperature range coverage

The substitute parts are grouped into two categories:

Direct Substitutes (PS9587-AX and PS9587L1-AX): These parts maintain all electrical parameters identical to the main part, including 10Mbps data rate, 25mA output current, 75ns propagation delay, and voltage supply range of 4.5V ~ 5.5V. Both are packaged in 8-DIP form factors, with PS9587L1-AX using the same 0.400" lead spacing. PS9587-AX uses 0.300" spacing and is in Preliminary product status.

Similar Alternatives (PS9513-AX and PS9513L1-AX): These parts meet the mandatory isolation, CMTI, and package requirements but operate at reduced data rate (1Mbps vs. 10Mbps) and output current (15mA vs. 25mA). Both feature extended voltage supply range (4.5V ~ 20V) and higher operating temperature maximum (100°C vs. 85°C). PS9513L1-AX uses 0.400" lead spacing matching the original part.

Parameter Comparison

Engineering Selection Recommendations

PS9587L1-AX (Renesas, Active Status): This is the optimal substitute for the discontinued CEL PS9587L1-AX. It maintains identical electrical specifications including 10Mbps data rate, 25mA output current, 75ns propagation delay, and identical package dimensions (8-DIP 0.400" lead spacing). Product status is Active with highest inventory availability (1577 units), ensuring long-term supply continuity. Full RoHS3 compliance and Moisture Sensitivity Level 1 rating match the original specification.

PS9587-AX (Renesas, Preliminary Status): This direct electrical equivalent operates at identical performance levels (10Mbps, 25mA, 75ns) with identical voltage supply range. However, it uses a different package footprint (8-DIP 0.300" lead spacing) and maintains Preliminary product status, which may carry lifecycle uncertainty. Selection is appropriate only when PCB layout accommodates the 0.300" spacing and long-term availability risk is acceptable.

PS9513-AX and PS9513L1-AX (Renesas, Active Status): These alternatives provide 5000Vrms isolation and 15kV/µs CMTI matching the primary isolation requirements, but with reduced performance specifications. Operating at 1Mbps data rate with 15mA output current and 750ns/500ns propagation delays, these parts are suitable only for applications not requiring 10Mbps speed or 25mA output drive capability. Extended voltage supply range (4.5V ~ 20V) and higher operating temperature maximum (100°C) provide additional design flexibility for specific applications. Both are in Active status with robust inventory. PS9513L1-AX uses matching 0.400" lead spacing.

Frequently Asked Questions (FAQ)

Q: Can PS9587-AX replace PS9587L1-AX in existing designs? A: Electrically, PS9587-AX is a complete functional equivalent with identical isolation, CMTI, data rate, output current, and propagation delay specifications. However, it uses 8-DIP 0.300" lead spacing versus 0.400" for the original part. PCB layout modification is required. Additionally, Preliminary product status presents lifecycle risk compared to the Active status PS9587L1-AX.

Q: What are the performance trade-offs for PS9513-AX and PS9513L1-AX? A: These parts provide identical isolation voltage (5000Vrms) and CMTI (15kV/µs), but reduce data rate from 10Mbps to 1Mbps, output current from 25mA to 15mA, and increase propagation delay from 75ns to 750ns/500ns. They are substitutes only for applications with reduced speed or drive requirements. Benefits include extended voltage supply range (up to 20V) and higher operating temperature maximum (100°C).

Q: Are there package compatibility concerns between substitute parts? A: PS9587L1-AX (Renesas substitute) and PS9513L1-AX both use 8-DIP 0.400" lead spacing, matching the original part and requiring no PCB changes. PS9587-AX and PS9513-AX use 0.300" spacing and require PCB layout modification. All parts maintain identical pin count and 8-DIP through-hole mounting type.

Q: Which substitute provides the best availability and product stability? A: PS9587L1-AX (Renesas) offers the strongest combination of direct electrical equivalence, Active product status, highest inventory availability (1577 units), identical package footprint, and matching voltage supply range. It is the primary recommended substitute for discontinued CEL PS9587L1-AX.

Q: Does REACH compliance status differ among substitutes? A: PS9587-AX and PS9587L1-AX maintain REACH Unaffected status matching the original part. PS9513-AX and PS9513L1-AX show REACH Affected status, introducing additional regulatory tracking requirements for certain applications or jurisdictions.
