Key Parameters

Substitute Part Grouping Explanation

Substitution of the SG-310SCF 33.3333MM3 is determined by the following critical parameters:

• Frequency Match: 33.3333 MHz (exact match required)
• Output Type: CMOS (must match)
• Package / Case: 4-SMD, No Lead (physical compatibility)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Base Resonator: Crystal (oscillator type)
• Type: XO (Standard) (functional classification)

The substitute part SG-8018CE 33.3333M-TJHSA0 meets these core substitution criteria. Both parts share identical frequency, output type, package configuration, and mounting method. The SG-8018CE series represents an active product line from EPSON with enhanced specifications and broader voltage compatibility, making it a viable replacement for the obsolete SG-310SCF.

Parameter Comparison

Engineering Selection Recommendations

The SG-8018CE 33.3333M-TJHSA0 is the designated substitute for the obsolete SG-310SCF 33.3333MM3. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental compliance.

The SG-8018CE offers an active product status, ensuring long-term availability and supply chain continuity. The substitute part provides improved frequency stability (±50ppm versus ±100ppm) and an extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C). The voltage supply range of 1.62V ~ 3.63V encompasses the original 3.3V specification, providing design flexibility.

Physical compatibility is maintained: both parts use identical 4-SMD, No Lead packaging with 3.20mm x 2.50mm footprints. The SG-8018CE exhibits a lower seated height (1.05mm versus 1.20mm), which may provide additional PCB layout advantages.

Frequently Asked Questions (FAQ)

Q: Can the SG-8018CE 33.3333M-TJHSA0 directly replace the SG-310SCF 33.3333MM3 on existing PCBs?

A: Yes. Both parts share identical package dimensions (3.20mm x 2.50mm), 4-SMD No Lead configuration, and surface mount mounting type. The footprint and pinout are compatible for direct PCB substitution.

Q: What are the key differences between these two parts?

A: The primary differences are product status (active versus obsolete), frequency stability (±50ppm versus ±100ppm), operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C), and supply voltage range (1.62V ~ 3.63V versus fixed 3.3V). The SG-8018CE also features lower maximum supply current (8.1mA versus 4.5mA) and reduced seated height (1.05mm versus 1.20mm).

Q: Are both parts RoHS compliant?

A: Yes. Both the SG-310SCF 33.3333MM3 and SG-8018CE 33.3333M-TJHSA0 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the frequency output of both oscillators?

A: Both parts output a fixed frequency of 33.3333 MHz with CMOS logic levels.

Q: Does the SG-8018CE work with 3.3V supply voltage?

A: Yes. The SG-8018CE supply voltage range of 1.62V ~ 3.63V includes 3.3V operation, making it fully compatible with designs using the original SG-310SCF 33.3333MM3.
