PS9513L1-AX Equivalent & Substitute Parts

Part Overview

The PS9513L1-AX is a logic output optoisolator manufactured by CEL, designed for high-voltage isolation applications requiring 5000Vrms isolation rating. This component features open collector output topology with 1Mbps data rate capability and 15kV/µs common mode transient immunity, suitable for industrial control, power management, and signal isolation circuits.

The PS9513L1-AX is currently discontinued at DiGi Electronics. Equivalent substitute parts are available from Renesas Electronics Corporation under the PS9513 series, which maintain identical electrical and functional specifications while offering active product status and improved supply availability.

Substitute Part Grouping Explanation

Substitution of the PS9513L1-AX optoisolator is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Isolation voltage rating: 5000Vrms (mandatory match)
• Output configuration: Open Collector topology (mandatory match)
• Data rate: 1Mbps (mandatory match)
• Common mode transient immunity: 15kV/µs minimum (mandatory match)
• Output current per channel: 15mA (mandatory match)
• Supply voltage range: 4.5V to 20V (mandatory match)
• Operating temperature range: -40°C to 100°C (mandatory match)
• Input configuration: 1 channel input, 0 channels on side 2 (mandatory match)

Mechanical Equivalence Criteria:

• Package type: 8-DIP (mandatory match)
• Mounting type: Through Hole (mandatory match)

Compliance Equivalence Criteria:

• RoHS3 compliance (mandatory match)
• Moisture Sensitivity Level: 1 (Unlimited) (mandatory match)
• REACH affected status (mandatory match)

The substitute parts PS9513-AX and PS9513L1-AX from Renesas Electronics Corporation satisfy all electrical, mechanical, and compliance requirements for direct substitution. Both parts maintain identical functional specifications and are manufactured to the same industry standards.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: PS9513L1-AX (Renesas Electronics Corporation)

The Renesas PS9513L1-AX is the direct equivalent substitute for the discontinued CEL PS9513L1-AX. This part maintains identical electrical specifications, package dimensions (8-DIP 0.400", 10.16mm), and compliance certifications. The Renesas variant carries active product status with confirmed inventory availability of 1981 pieces. Selection of this part eliminates supply chain risk associated with discontinued components while preserving all functional and mechanical compatibility with existing circuit designs.

Secondary Substitute: PS9513-AX (Renesas Electronics Corporation)

The Renesas PS9513-AX provides electrical equivalence across all critical parameters including isolation voltage, output configuration, data rate, and CMTI rating. This part differs in package body length (8-DIP 0.300", 7.62mm versus 0.400", 10.16mm). The PS9513-AX is suitable for applications where PCB layout accommodates the reduced package footprint. This variant offers higher inventory availability (6850 pieces) and active product status. Mechanical compatibility with existing through-hole PCB designs requires verification of pad spacing and board layout constraints.

Compliance and Supply Considerations:

Both Renesas substitutes maintain ROHS3 compliance, REACH affected status, and EAR99 export classification identical to the original CEL component. Selection between PS9513-AX and PS9513L1-AX (Renesas) depends on PCB layout requirements and package body length constraints rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: Can PS9513-AX (Renesas) replace PS9513L1-AX (CEL) in existing designs?

A: Electrical substitution is complete. The PS9513-AX differs in package body length (0.300" versus 0.400"). Verify PCB pad spacing and through-hole positioning before implementation. If the original design requires the 0.400" body length, use PS9513L1-AX (Renesas) instead.

Q: What are the critical parameters that must match for optoisolator substitution?

A: Isolation voltage rating (5000Vrms), output type (Open Collector), data rate (1Mbps), common mode transient immunity (15kV/µs), output current (15mA), supply voltage range (4.5V to 20V), operating temperature range (-40°C to 100°C), and package type (8-DIP through-hole) must all match exactly.

Q: Why is the CEL PS9513L1-AX discontinued?

A: The provided data indicates discontinuation at DiGi Electronics. Renesas Electronics Corporation maintains active production of functionally equivalent PS9513 series components.

Q: Are there differences in propagation delay between the CEL and Renesas versions?

A: No. Both versions specify identical maximum propagation delays: tpLH 750ns and tpHL 500ns.

Q: Can I use PS9513-AX if my PCB is designed for PS9513L1-AX?

A: Electrical functionality is identical. Physical compatibility depends on PCB layout. The PS9513-AX package body is 0.100" shorter (0.300" versus 0.400"). Measure the distance between through-hole pads on your PCB. If pad spacing matches the shorter body length, substitution is mechanically compatible. If not, use PS9513L1-AX (Renesas).

Q: Do the Renesas substitutes maintain the same isolation voltage rating?

A: Yes. Both PS9513-AX and PS9513L1-AX (Renesas) maintain 5000Vrms isolation rating identical to the original CEL component.

Q: What is the inventory status of substitute parts?

A: PS9513-AX (Renesas) has 6850 pieces in stock. PS9513L1-AX (Renesas) has 1981 pieces in stock. Both are available as new original components.

Q: Are compliance certifications identical across all three parts?

A: Yes. All three parts (CEL PS9513L1-AX, Renesas PS9513-AX, and Renesas PS9513L1-AX) are ROHS3 compliant, REACH affected, classified as EAR99, and carry HTSUS code 8541.49.8000 with MSL rating of 1 (Unlimited).
