Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1315-5 is determined by strict equivalence across the following critical parameters:

• Manufacturer and Base Product Number: Both the main part and substitute must originate from Analog Devices Inc./Maxim Integrated and share the DS1315 base product number to ensure functional and pin-level compatibility.
• Package and Pinout: The 16-DIP (0.300", 7.62mm) package and through-hole mounting type must be identical to ensure mechanical and electrical compatibility with existing PCB layouts.
• Electrical Specifications: Supply voltage range (4.5V ~ 5.5V), battery backup voltage (2.5V ~ 3.7V), and timekeeping current (1.3mA @ 5V) must match exactly.
• Functional Characteristics: Time format (HH:MM:SS:hh, 12/24 hr), date format (YY-MM-DD-dd), parallel interface, and leap year support must be identical.
• Operating Temperature Range: The 0°C ~ 70°C operating range must be maintained.

Parameter Comparison

Engineering Selection Recommendations

The DS1315-5+ is a direct functional equivalent to the DS1315-5 and is the appropriate substitute for new designs and component replacement applications.

Product Status Consideration: The DS1315-5 is obsolete, while the DS1315-5+ maintains active product status. This ensures ongoing availability and manufacturer support for the DS1315-5+ variant.

Compliance Advantage: The DS1315-5+ achieves ROHS3 compliance, whereas the DS1315-5 is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the DS1315-5+ is the required selection.

Packaging Difference: The DS1315-5 is supplied in standard packaging, while the DS1315-5+ is supplied in tube packaging. This distinction affects handling, storage, and automated assembly processes but does not impact electrical or functional performance.

All other electrical, functional, and regulatory parameters remain identical between the two parts, confirming full substitutability at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can the DS1315-5+ be used as a direct replacement for the DS1315-5 in existing designs?

A: Yes. The DS1315-5+ is electrically and functionally identical to the DS1315-5. Both parts share the same pinout, package dimensions (16-DIP, 0.300", 7.62mm), supply voltage requirements (4.5V ~ 5.5V), battery backup voltage (2.5V ~ 3.7V), and timekeeping specifications. No circuit modifications are required.

Q: What is the difference between the DS1315-5 and DS1315-5+?

A: The primary differences are product status and compliance certification. The DS1315-5 is obsolete and RoHS non-compliant, while the DS1315-5+ is an active product with ROHS3 compliance. Packaging also differs: DS1315-5 uses standard packaging, and DS1315-5+ uses tube packaging. Electrical and functional specifications are identical.

Q: Why is the DS1315-5 classified as obsolete?

A: The DS1315-5 has reached end-of-life status with the manufacturer. The DS1315-5+ represents the current active equivalent and is the recommended selection for all new applications and component procurement.

Q: Are there any compatibility concerns when substituting the DS1315-5+ for the DS1315-5?

A: No compatibility concerns exist. The 16-DIP through-hole package, pinout, electrical characteristics, and functional behavior are identical. The parts are mechanically and electrically interchangeable.

Q: Does the tube packaging of the DS1315-5+ affect its performance?

A: No. Packaging format affects handling, storage, and assembly processes but does not impact electrical performance, reliability, or functional characteristics. Both packaging types provide equivalent moisture sensitivity protection (MSL 1, Unlimited).

Q: Is the DS1315-5+ suitable for applications requiring RoHS compliance?

A: Yes. The DS1315-5+ is ROHS3 compliant and is the appropriate selection for applications subject to RoHS regulations. The DS1315-5 is not RoHS compliant and should not be used in RoHS-regulated applications.
