SG-310SCF 2.0000MM0 Equivalent & Substitute Parts

Part Overview

The SG-310SCF 2.0000MM0 is a 2 MHz XO (Standard) CMOS oscillator manufactured by EPSON, designed for applications requiring a fixed 2 MHz frequency output with 3.3V supply operation. This part features standby (power down) functionality and is housed in a 4-SMD, No Lead surface mount package with dimensions of 3.20mm x 2.50mm.

The SG-310SCF 2.0000MM0 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support long-term product support for systems currently using this oscillator.

Substitute Part Grouping Explanation

The SG-8018CE 2.0000M-TJHSA0 qualifies as a functional substitute for the SG-310SCF 2.0000MM0 based on the following critical parameters:

Matching Parameters:

• Frequency: 2 MHz (identical)
• Type: XO (Standard) (identical)
• Output: CMOS (identical)
• Mounting Type: Surface Mount (identical)
• Package / Case: 4-SMD, No Lead (identical)
• Size / Dimension: 3.20mm x 2.50mm (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Differing Parameters:

Engineering Selection Recommendations

The SG-8018CE 2.0000M-TJHSA0 is an active product with current manufacturing support from EPSON, making it the primary substitute for the obsolete SG-310SCF 2.0000MM0. Both parts maintain identical frequency, output type, package configuration, and physical dimensions, ensuring direct mechanical and electrical compatibility at the board level.

The SG-8018CE offers improved frequency stability (±50ppm versus ±100ppm) and an extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C). The supply voltage range of 1.62V ~ 3.63V encompasses the original 3.3V specification, providing design flexibility for systems operating at this voltage.

Design considerations include the increased maximum supply current (8.1mA versus 1.5mA) and the functional difference between standby (power down) and enable/disable control modes. Systems requiring the original standby functionality must evaluate whether enable/disable control meets application requirements. Both parts maintain ROHS3 compliance and MSL 1 rating, supporting equivalent environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the SG-8018CE 2.0000M-TJHSA0 directly replace the SG-310SCF 2.0000MM0 without PCB modifications?

A: Yes. Both parts share identical package type (4-SMD, No Lead), physical dimensions (3.20mm x 2.50mm), and pinout configuration. No PCB layout changes are required for mechanical and electrical substitution.

Q: What is the impact of the increased supply current specification?

A: The SG-8018CE specifies a maximum supply current of 8.1mA compared to 1.5mA for the SG-310SCF. Power supply design must accommodate this higher current draw. For battery-powered or low-power applications, this increase may affect system power budget calculations and battery life projections.

Q: How do the control functions differ between these parts?

A: The SG-310SCF provides standby (power down) functionality, reducing current consumption when the oscillator is disabled. The SG-8018CE provides enable/disable control, which also reduces current consumption (4.6mA disable current) but operates through a different control mechanism. Applications must verify that enable/disable control is compatible with existing system firmware and control logic.

Q: Does the improved frequency stability of the SG-8018CE affect system performance?

A: The SG-8018CE provides ±50ppm frequency stability compared to ±100ppm for the SG-310SCF. This represents a tighter tolerance and may improve timing accuracy in applications sensitive to frequency drift. Systems designed for ±100ppm tolerance will operate within specification with the improved stability of the substitute part.

Q: Are there supply chain or packaging differences?

A: The SG-8018CE 2.0000M-TJHSA0 is available in Tape & Reel (TR) packaging with active production status. The SG-310SCF is obsolete with limited remaining inventory. The SG-8018CE provides assured long-term availability for new production and design updates.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001. Regulatory and environmental requirements are equivalent between the two parts.
