DS1216C Equivalent & Substitute Parts

Part Overview

The DS1216C is a Smart/RAM memory integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for 5V operation with 64K/256K capacity in a 28-DIP through-hole package. This component is classified as obsolete, making identification of compatible substitute parts essential for legacy system maintenance and board-level repairs. The DS1216C operates within a 4.5V to 5.5V supply voltage range and supports operating temperatures from 0°C to 70°C, typical for industrial and consumer applications requiring non-volatile memory functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1216C is based on the following critical parameters that must align between the main part and substitute:

• Voltage Supply Range: Both parts must operate within 4.5V to 5.5V to ensure direct compatibility with existing power distribution circuits
• Operating Temperature Range: Both parts must support 0°C to 70°C operation to maintain functional equivalence across environmental conditions
• Package Type: Both parts must use 28-DIP through-hole packaging with 0.600" (15.24mm) spacing to ensure mechanical fit on legacy PCBs
• Mounting Type: Through-hole mounting is required for compatibility with existing board layouts
• Manufacturer Source: Parts from Analog Devices Inc./Maxim Integrated maintain design consistency and supply chain reliability

The DS1244Y-70+ meets these substitution criteria as a manufacturer-recommended alternative, sharing identical voltage specifications, operating temperature range, and 28-DIP package configuration.

Parameter Comparison

Engineering Selection Recommendations

The DS1244Y-70+ is the manufacturer-designated substitute for the DS1216C. Selection of this substitute is supported by:

• Electrical Compatibility: Identical supply voltage range (4.5V ~ 5.5V) and operating temperature specifications (0°C ~ 70°C) ensure direct functional replacement without circuit modification
• Physical Compatibility: Both components use 28-DIP through-hole packaging with matching 0.600" (15.24mm) spacing, enabling direct PCB socket replacement
• Product Status: The DS1244Y-70+ maintains active production status, ensuring availability for legacy system support and repair applications
• Compliance Improvement: The DS1244Y-70+ achieves ROHS3 compliance, providing environmental and regulatory advantages over the non-compliant DS1216C for new production runs or system upgrades

Frequently Asked Questions (FAQ)

Q: Can the DS1244Y-70+ be used as a direct replacement for the DS1216C?

A: Yes. Both components share identical supply voltage (4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C), and 28-DIP package configuration. Direct socket substitution is supported without circuit modification.

Q: What is the primary difference between these parts?

A: The DS1244Y-70+ is an active production component with ROHS3 compliance, while the DS1216C is obsolete and RoHS non-compliant. The DS1244Y-70+ is a Real Time Clock (RTC) Phantom Time Chip with integrated timekeeping features, whereas the DS1216C is classified as a Smart/RAM memory device.

Q: Are there any package considerations for substitution?

A: Both parts use 28-DIP through-hole packaging with identical 0.600" (15.24mm) spacing. No package adapter or PCB modification is required for mechanical compatibility.

Q: Does the DS1244Y-70+ require any circuit modifications?

A: No. Electrical specifications are identical, including supply voltage range and operating temperature. Existing circuit designs require no modification for substitution.

Q: What is the moisture sensitivity level for both parts?

A: Both the DS1216C and DS1244Y-70+ have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
