Key Parameters

Substitute Part Grouping Explanation

Substitution of the YJ2700004 is determined by the following critical parameters that must remain constant across equivalent parts:

• Frequency: 27.0000 MHz (exact match required)
• Output Type: CMOS
• Voltage Supply: 3.3V
• Operating Temperature Range: -40°C to 85°C minimum
• Oscillator Type: VCXO
• Packaging: Tape & Reel with 4-SMD, No Lead configuration

The VG-4231CE 27.0000M-PSCM3 manufactured by EPSON satisfies all substitution criteria. This part maintains identical frequency, output characteristics, supply voltage, and temperature range specifications while offering active product status and enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

The VG-4231CE 27.0000M-PSCM3 is the qualified substitute for the obsolete YJ2700004. Selection is based on the following engineering criteria:

• All critical electrical parameters match the original specification: 27 MHz frequency, CMOS output, 3.3V supply, and -40°C to 85°C operating range
• The substitute maintains identical packaging format (Tape & Reel, 4-SMD, No Lead)
• Active product status ensures long-term availability and supply chain continuity
• Both parts maintain equivalent RoHS and REACH compliance certifications
• Moisture sensitivity level remains unchanged at MSL 1 (Unlimited)

The dimensional difference (footprint size increase from 2.50mm x 2.00mm to 3.20mm x 2.50mm) requires PCB layout verification to confirm compatibility with existing board designs.

Frequently Asked Questions (FAQ)

Q: Can the VG-4231CE 27.0000M-PSCM3 be used as a direct replacement for the YJ2700004?

A: Yes, provided PCB layout accommodates the larger footprint dimensions (3.20mm x 2.50mm versus 2.50mm x 2.00mm). All electrical parameters, frequency, output type, supply voltage, and operating temperature range are identical.

Q: What is the primary reason for substitution?

A: The YJ2700004 has reached obsolete status. The VG-4231CE 27.0000M-PSCM3 maintains active product status with equivalent specifications and superior availability.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant and REACH unaffected. The substitute carries ROHS3 certification, representing current compliance standards. Moisture sensitivity level remains identical at MSL 1 (Unlimited).

Q: What are the key parameters that must match for substitution?

A: Frequency (27.0000 MHz), oscillator type (VCXO), output type (CMOS), supply voltage (3.3V), operating temperature range (-40°C to 85°C), and packaging format (Tape & Reel, 4-SMD, No Lead) must remain constant.

Q: Does the substitute part require any design modifications?

A: PCB layout verification is required due to the footprint size increase. The substitute is 0.028" longer and 0.019" wider than the original part. No electrical design modifications are necessary.
