Substitute Part Grouping Explanation

Substitution eligibility for the PS2561AL1-1-F3-H-A is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Transistor
• Package / Case: 4-DIP (0.400", 10.16mm)
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 100°C

Secondary Compatibility Parameters:

• Voltage - Output (Max): 70V
• Current - Output / Channel: 30mA
• Vce Saturation (Max): 300mV
• Input Type: DC

Substitute parts are classified into two categories:

Direct Equivalent: PS2561AL1-1-H-A maintains identical electrical specifications and package configuration, differing only in manufacturer designation and product status.

Similar Substitute: PS2581AL1-A shares core isolation voltage, channel count, output type, and package specifications. This part exhibits broader current transfer ratio range (50% to 400% @ 5mA) compared to the main part specification (80% to 160% @ 5mA), indicating different internal design parameters while maintaining functional compatibility within the specified operating envelope.

Engineering Selection Recommendations

For Active Production Requirements:

PS2561AL1-1-H-A is the primary substitute for PS2561AL1-1-F3-H-A. This part maintains identical electrical and mechanical specifications while offering active product status from Renesas Electronics Corporation. The direct equivalence across all critical parameters ensures pin-for-pin and functional compatibility. RoHS3 compliance certification is provided.

For Legacy System Maintenance:

PS2581AL1-A serves as a functional alternative where the broader current transfer ratio specification (50% to 400% @ 5mA) is acceptable within circuit design margins. This part is classified as "Not For New Designs" but remains available in high inventory (35100 Pcs). The identical isolation voltage, channel count, output type, package configuration, and operating temperature range support functional substitution in existing applications. RoHS3 compliance is confirmed.

Compliance Considerations:

Both substitute parts maintain REACH Affected status and EAR99 ECCN classification consistent with the main part. Moisture sensitivity level remains at MSL 1 (Unlimited) across all variants.

Frequently Asked Questions (FAQ)

Q: Can PS2561AL1-1-H-A be used as a direct replacement for PS2561AL1-1-F3-H-A?

A: Yes. PS2561AL1-1-H-A is a direct equivalent. All electrical parameters, isolation voltage, channel configuration, output type, and 4-DIP package specifications are identical. The primary difference is manufacturer designation and active product status.

Q: What is the key difference between PS2561AL1-1-H-A and PS2581AL1-A?

A: Both parts share identical isolation voltage (5000Vrms), channel count (1), output type (transistor), and 4-DIP package. The PS2581AL1-A exhibits a broader current transfer ratio range (50% to 400% @ 5mA) compared to PS2561AL1-1-H-A (80% to 160% @ 5mA). This indicates different internal design characteristics while maintaining functional compatibility within specified operating parameters.

Q: Are there any packaging differences between these optoisolators?

A: All three parts use identical 4-DIP (0.400", 10.16mm) through-hole packaging. PCB layout and mounting procedures remain unchanged across substitutions.

Q: What is the product status significance for each part?

A: PS2561AL1-1-F3-H-A is obsolete, requiring substitution for new procurement. PS2561AL1-1-H-A is active and recommended for ongoing production. PS2581AL1-A is classified as "Not For New Designs" but remains available for legacy system support.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are REACH Affected, classified as EAR99, and maintain MSL 1 (Unlimited) moisture sensitivity level. PS2561AL1-1-H-A and PS2581AL1-A both carry RoHS3 compliance certification.

Q: Can PS2581AL1-A be used in applications requiring the tighter current transfer ratio specification of PS2561AL1-1-F3-H-A?

A: Circuit design validation is required. PS2581AL1-A's broader current transfer ratio range (50% to 400% @ 5mA) encompasses the PS2561AL1-1-F3-H-A specification (80% to 160% @ 5mA). Application-specific gain and switching characteristics must be evaluated to confirm functional compatibility.
