Engineering Selection Recommendations

Primary Substitute: PS2533-1-A (Renesas Electronics Corporation)

The Renesas Electronics Corporation PS2533-1-A represents the direct parametric equivalent to the discontinued CEL PS2533-1-A. This part maintains active product status with significantly higher inventory availability (10,667 units). Both components share identical electrical specifications, mechanical packaging, and regulatory compliance certifications (ROHS3, REACH Affected, EAR99). The Renesas variant is supplied in tube packaging format.

Secondary Substitute: PS2533-1-V-A (Renesas Electronics Corporation)

The PS2533-1-V-A from Renesas Electronics Corporation is a parametric equivalent variant within the NEPOC series. This part maintains all electrical and mechanical specifications identical to the main part number, with active product status and substantial inventory availability (9,560 units). The "-V-A" suffix indicates a variant designation within the same base product family (PS2533). This component is also supplied in tube packaging and carries identical regulatory compliance.

Selection Basis:

Both substitute parts are selected based on:

• Complete parametric equivalence across all electrical specifications
• Identical mechanical form factor and through-hole mounting compatibility
• Active product status ensuring continued availability
• ROHS3 compliance and REACH affected status matching the original part
• EAR99 export classification consistency
• Moisture sensitivity level 1 (unlimited shelf life)

Frequently Asked Questions (FAQ)

Q: Can PS2533-1-A (Renesas) be used as a direct replacement for PS2533-1-A (CEL)?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The Renesas variant maintains identical isolation voltage (5000Vrms), Darlington output configuration, current transfer ratio range (1500% to 6500% @ 1mA), output voltage/current ratings, timing characteristics, and 4-DIP through-hole package format. Direct pin-for-pin substitution is supported without circuit modification.

Q: What is the difference between PS2533-1-A and PS2533-1-V-A?

A: Both parts are parametrically equivalent with identical electrical performance and mechanical packaging. The "-V-A" suffix indicates a variant designation within the NEPOC series base product family (PS2533). No functional or performance differences exist between these variants for the specified electrical and mechanical parameters.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both PS2533-1-A (Renesas) and PS2533-1-V-A (Renesas) are ROHS3 compliant, matching the compliance status of the original CEL part. Both are also REACH affected and classified as EAR99 for export purposes.

Q: What is the moisture sensitivity level for these optoisolators?

A: All three parts (CEL PS2533-1-A, Renesas PS2533-1-A, and Renesas PS2533-1-V-A) have a moisture sensitivity level of 1, indicating unlimited shelf life without special moisture control requirements during storage or handling.

Q: Can these parts operate across the full temperature range specified?

A: Yes. All substitute parts maintain the operating temperature range of -55°C to 100°C, supporting applications requiring extended temperature performance.

Q: What packaging format is supplied for the Renesas variants?

A: Both Renesas substitute parts (PS2533-1-A and PS2533-1-V-A) are supplied in tube packaging, which is standard for through-hole DIP components.

Q: Are there any differences in inventory availability between the substitute parts?

A: The Renesas PS2533-1-A has higher inventory availability (10,667 units) compared to the PS2533-1-V-A (9,560 units). Both variants maintain substantial stock levels for production requirements.
