Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACOL-16.000MHZ-EK is determined by the following critical parameters:

• Frequency Match: 16 MHz (exact)
• Output Compatibility: HCMOS and TTL output levels
• Supply Voltage: 3.3V
• Frequency Stability: ±30ppm
• Operating Temperature Range: -20°C ~ 70°C minimum
• Maximum Supply Current: 20mA or less
• Base Resonator Type: Crystal
• Oscillator Type: XO (Standard)
• Mounting Configuration: Through Hole
• Compliance: ROHS3 Compliant

The ACHL-16.000MHZ-EK qualifies as a direct substitute based on matching all critical electrical parameters. Physical package differences exist between the main part and substitute, requiring mechanical compatibility verification during integration.

Parameter Comparison

Engineering Selection Recommendations

The ACHL-16.000MHZ-EK is the manufacturer-recommended substitute for the obsolete ACOL-16.000MHZ-EK. Both parts maintain identical electrical specifications including frequency, output type, supply voltage, frequency stability, operating temperature range, and maximum supply current. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary distinction between these parts is packaging configuration. The ACHL-16.000MHZ-EK uses an 8-DIP half-size metal can package, while the ACOL-16.000MHZ-EK uses a 14-DIP full-size metal can package. The substitute part occupies less board space (13.20mm x 13.20mm versus 20.20mm x 12.60mm) and maintains compatible through-hole mounting. The ACHL variant is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the ACHL-16.000MHZ-EK directly replace the ACOL-16.000MHZ-EK in existing designs?

A: Electrical compatibility is complete. The substitute part delivers identical frequency, output levels, supply voltage, and current specifications. Physical package differences require PCB layout modification to accommodate the smaller 8-DIP half-size metal can footprint.

Q: What are the key differences between these oscillators?

A: The ACOL uses a 14-DIP full-size metal can package measuring 20.20mm x 12.60mm. The ACHL uses an 8-DIP half-size metal can package measuring 13.20mm x 13.20mm. All electrical parameters remain identical.

Q: Is the ACHL-16.000MHZ-EK available for new designs?

A: Yes. The ACHL-16.000MHZ-EK maintains active product status with current manufacturing and distribution. The ACOL-16.000MHZ-EK is obsolete and no longer produced.

Q: Do both parts meet current compliance requirements?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and distribution.

Q: What is the moisture sensitivity level for these oscillators?

A: Both the ACOL-16.000MHZ-EK and ACHL-16.000MHZ-EK carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
