• Delay to 1st Tap: 16.5ns
• Tap Increment: 250 ps
• Available Total Delays: 63.75ns
• Number of Independent Delays: 1
• Voltage - Supply: 4.75V ~ 5.25V
• Operating Temperature: 0°C ~ 70°C
• Package / Case: 16-SOIC (0.295", 7.50mm Width)

All identified substitutes maintain identical electrical specifications and package dimensions, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

DS1023S-25+ (Direct Substitute): This part is the primary substitute for the obsolete DS1023S-25. It maintains identical electrical and mechanical specifications while offering Active product status. The DS1023S-25+ is ROHS3 compliant, addressing regulatory requirements for new designs and procurement. This part is available in Tube packaging.

DS1023S-25+W (Parametric Equivalent): This part provides equivalent electrical and mechanical performance to the DS1023S-25. It is also Active and ROHS3 compliant. The DS1023S-25+W offers an alternative sourcing option with identical functional parameters.

Both substitute parts eliminate the obsolescence risk associated with the DS1023S-25 while maintaining full electrical and mechanical compatibility. Selection between DS1023S-25+ and DS1023S-25+W should be based on packaging requirements and supplier availability.

Frequently Asked Questions (FAQ)

Q: Can DS1023S-25+ directly replace DS1023S-25 in existing designs? A: Yes. The DS1023S-25+ maintains identical electrical specifications (256 taps, 16.5ns delay to first tap, 250 ps tap increment, 63.75ns total delay, 4.75V–5.25V supply, 0°C–70°C operating range) and package dimensions (16-SOIC, 0.295" × 7.50mm). No circuit modifications are required.

Q: What is the difference between DS1023S-25+ and DS1023S-25+W? A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is product status and availability. Both are Active and ROHS3 compliant. Selection should be based on packaging format and supplier stock.

Q: Why is the DS1023S-25 marked as Obsolete? A: The DS1023S-25 has reached end-of-life status. DS1023S-25+ and DS1023S-25+W are the current active alternatives from the same manufacturer.

Q: Are there any compliance differences between the main part and substitutes? A: Yes. The DS1023S-25 is RoHS non-compliant, while both DS1023S-25+ and DS1023S-25+W are ROHS3 compliant. Both substitutes maintain REACH Unaffected status. For new designs or regulated applications, the compliant substitutes are required.

Q: What is the Moisture Sensitivity Level (MSL) for these parts? A: All three parts (DS1023S-25, DS1023S-25+, and DS1023S-25+W) have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use these parts interchangeably in production? A: Yes, provided electrical and mechanical requirements are met. The DS1023S-25+ and DS1023S-25+W are functionally equivalent and can be used interchangeably based on availability and packaging preferences.
