Substitute Part Grouping Explanation

Substitution of the DS18030-010 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 10kΩ (exact match required)
• Number of Circuits: 2 (exact match required)
• Number of Taps: 256 (exact match required)
• Interface Protocol: I2C (exact match required)
• Supply Voltage Range: 2.7V ~ 5.5V (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Tolerance: ±20% (exact match required)
• Temperature Coefficient: 750ppm/°C (exact match required)
• Wiper Resistance: 400Ω typical (exact match required)
• Memory Type: Volatile (exact match required)
• Features: Selectable Address (exact match required)

The DS1803E-010+ meets all electrical and functional specifications of the DS18030-010. The primary difference is packaging format: the DS18030-010 uses through-hole mounting (16-PDIP), while the DS1803E-010+ employs surface-mount technology (14-TSSOP). This substitution is valid only when PCB layout and assembly capabilities support surface-mount components.

Parameter Comparison

Engineering Selection Recommendations

The DS1803E-010+ is the direct functional equivalent of the DS18030-010 across all electrical and operational parameters. Selection between these parts depends on the following factors:

Product Status: The DS18030-010 is obsolete, while the DS1803E-010+ maintains active production status. For new designs or long-term system support, the DS1803E-010+ is the appropriate choice.

Compliance Requirements: The DS1803E-010+ is ROHS3 compliant, whereas the DS18030-010 is RoHS non-compliant. Applications subject to RoHS regulations must use the DS1803E-010+.

Packaging and Assembly: The DS18030-010 requires through-hole assembly on PCBs with DIP socket compatibility. The DS1803E-010+ requires surface-mount assembly capability. PCB redesign and reflow soldering processes are necessary when transitioning from DS18030-010 to DS1803E-010+.

Inventory and Availability: The DS1803E-010+ has significantly higher inventory availability (6108 units) compared to the DS18030-010 (1095 units), supporting sustained supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the DS1803E-010+ directly replace the DS18030-010 without circuit modifications?

A: Electrical functionality is fully compatible. However, physical package differences require PCB layout changes. The DS18030-010 uses a 16-pin DIP package for through-hole mounting, while the DS1803E-010+ uses a 14-pin TSSOP package for surface-mount assembly. Pin-to-pin functional mapping must be verified against device datasheets before implementation.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution requires exact equivalence in resistance value (10kΩ), circuit count (2), tap count (256), interface protocol (I2C), supply voltage range (2.7V ~ 5.5V), operating temperature range (-40°C ~ 85°C), tolerance (±20%), temperature coefficient (750ppm/°C), wiper resistance (400Ω typical), memory type (volatile), and address selectability features.

Q: Are there compliance differences between these parts?

A: Yes. The DS1803E-010+ is ROHS3 compliant, while the DS18030-010 is RoHS non-compliant. Applications requiring RoHS compliance must use the DS1803E-010+. Both parts are REACH unaffected and classified under ECCN EAR99.

Q: What assembly process changes are required when switching from DS18030-010 to DS1803E-010+?

A: The DS18030-010 uses through-hole assembly with DIP sockets. The DS1803E-010+ requires surface-mount assembly with reflow soldering. PCB footprint redesign is mandatory, and assembly equipment must support TSSOP package handling.

Q: Is the DS1803E-010+ the only available substitute for the DS18030-010?

A: Based on the provided substitute list, the DS1803E-010+ is the identified equivalent part meeting all electrical and functional specifications of the DS18030-010.
