Substitute Part Grouping Explanation

The ASD1-4.000MHZ-EC-T3 has one identified parametric equivalent: ASD1-4.000MHZ-EC-T. Substitution is valid based on the following criteria:

• Identical frequency specification (4 MHz)
• Identical output type (HCMOS)
• Identical supply voltage (3V)
• Identical frequency stability (±50ppm)
• Identical operating temperature range (-20°C ~ 70°C)
• Identical package and case (4-SMD, No Lead)
• Identical enable/disable function
• Identical RoHS3 compliance status
• Same manufacturer series (ASD)

The primary difference between these parts is packaging format: the main part (ASD1-4.000MHZ-EC-T3) uses standard packaging, while the substitute (ASD1-4.000MHZ-EC-T) is supplied in Tape & Reel format. Both parts maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ASD1-4.000MHZ-EC-T3 and ASD1-4.000MHZ-EC-T are active production parts from Abracon LLC with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements:

The ASD1-4.000MHZ-EC-T3 is suitable for applications requiring standard packaging with lower maximum supply current (4mA). The ASD1-4.000MHZ-EC-T provides the same electrical and mechanical specifications in Tape & Reel packaging format, which is standard for high-volume automated assembly operations. The maximum supply current specification differs (5.5mA vs 4mA), which should be evaluated against circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can ASD1-4.000MHZ-EC-T be used as a direct replacement for ASD1-4.000MHZ-EC-T3?

A: Yes. Both parts maintain identical electrical specifications (4 MHz frequency, HCMOS output, 3V supply, ±50ppm stability, -20°C to 70°C operating range) and mechanical compatibility (4-SMD, No Lead package, identical dimensions). The primary difference is packaging format.

Q: What is the difference between the packaging formats?

A: ASD1-4.000MHZ-EC-T3 uses standard packaging, while ASD1-4.000MHZ-EC-T is supplied in Tape & Reel format. Tape & Reel packaging is optimized for automated pick-and-place assembly in high-volume production environments.

Q: Are there differences in electrical performance between these parts?

A: The maximum supply current specification differs: ASD1-4.000MHZ-EC-T3 specifies 4mA maximum, while ASD1-4.000MHZ-EC-T specifies 5.5mA maximum. All other electrical parameters, including frequency stability, operating temperature range, and disable mode current, are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Which part should be selected for new designs?

A: Selection depends on procurement volume and assembly process. For high-volume automated assembly, ASD1-4.000MHZ-EC-T (Tape & Reel) is standard. For lower volumes or manual assembly, either part is suitable based on availability and supply chain requirements.
