Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASCO-2.000MHZ-EK-T are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Frequency: 2 MHz (exact match required)
• Type: XO (Standard)
• Output: CMOS
• Function: Enable/Disable
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, No Lead
• Base Resonator: Crystal

Secondary Compatibility Parameters:

• Voltage - Supply: Must support 3.3V operation
• Frequency Stability: ±30ppm or better
• Operating Temperature: Must encompass -20°C ~ 70°C range
• Current - Supply (Max): Must not exceed application requirements
• Physical dimensions and height must be compatible with PCB layout

Two substitute categories are identified:

Category 1 - Parametric Equivalent (Active Status): ASCO-2.000MHZ-EK-T3 provides identical electrical and mechanical specifications to the original part with Active product status, ensuring long-term availability.

Category 2 - MFR Recommended Substitute (Extended Capability): SG-8018CG 2.0000M-TJHSA0 meets all primary matching criteria with extended voltage range and operating temperature, though with different physical dimensions and higher current consumption.

Parameter Comparison

Engineering Selection Recommendations

ASCO-2.000MHZ-EK-T3 (Abracon LLC) is the primary substitute for the obsolete ASCO-2.000MHZ-EK-T. This part maintains identical electrical specifications, frequency stability, operating temperature range, and physical dimensions. Both parts are ROHS3 Compliant and REACH Unaffected. The ASCO-2.000MHZ-EK-T3 carries Active product status, ensuring sustained manufacturing and supply chain availability. This substitute requires no design modifications and provides direct form-fit-function replacement.

SG-8018CG 2.0000M-TJHSA0 (EPSON) serves as an alternative substitute when extended operating temperature range (-40°C ~ 105°C) or wider supply voltage range (1.62V ~ 3.63V) is beneficial. This part meets all primary functional criteria and maintains ROHS3 Compliance and REACH Unaffected status. However, the SG-8018CG exhibits larger physical dimensions (2.50mm x 2.00mm versus 1.60mm x 1.20mm), higher maximum supply current (8.1mA versus 4.5mA), and reduced frequency stability (±50ppm versus ±30ppm). PCB layout verification is required to confirm compatibility with the larger footprint. This substitute is suitable for applications where the extended environmental specifications provide design margin benefits.

Frequently Asked Questions (FAQ)

Q: Can ASCO-2.000MHZ-EK-T3 be used as a direct replacement for ASCO-2.000MHZ-EK-T?

A: Yes. The ASCO-2.000MHZ-EK-T3 is a parametric equivalent with identical electrical and mechanical specifications. No design modifications are required. Both parts operate at 3.3V, deliver ±30ppm frequency stability, and are packaged in 4-SMD, No Lead configuration with 1.60mm x 1.20mm dimensions.

Q: What are the key differences between ASCO-2.000MHZ-EK-T3 and SG-8018CG 2.0000M-TJHSA0?

A: The primary differences are: (1) Physical dimensions: ASCO-2.000MHZ-EK-T3 is 1.60mm x 1.20mm; SG-8018CG is 2.50mm x 2.00mm; (2) Frequency stability: ASCO-2.000MHZ-EK-T3 is ±30ppm; SG-8018CG is ±50ppm; (3) Maximum supply current: ASCO-2.000MHZ-EK-T3 is 4.5mA; SG-8018CG is 8.1mA; (4) Operating temperature: ASCO-2.000MHZ-EK-T3 is -20°C ~ 70°C; SG-8018CG is -40°C ~ 105°C; (5) Supply voltage: ASCO-2.000MHZ-EK-T3 is 3.3V; SG-8018CG is 1.62V ~ 3.63V.

Q: Will SG-8018CG 2.0000M-TJHSA0 fit in the same PCB footprint as ASCO-2.000MHZ-EK-T?

A: No. The SG-8018CG has larger physical dimensions (2.50mm x 2.00mm) compared to the original part (1.60mm x 1.20mm). PCB layout must be verified and potentially modified to accommodate the larger footprint. Height remains compatible at 0.70mm maximum.

Q: Are all substitute parts ROHS3 Compliant?

A: Yes. Both ASCO-2.000MHZ-EK-T3 and SG-8018CG 2.0000M-TJHSA0 are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the original ASCO-2.000MHZ-EK-T.

Q: Which substitute should be selected for new designs?

A: ASCO-2.000MHZ-EK-T3 is recommended for new designs requiring direct compatibility with existing specifications. SG-8018CG 2.0000M-TJHSA0 is suitable when extended operating temperature range or wider supply voltage tolerance provides design benefits and PCB layout can accommodate the larger footprint.

Q: What is the Moisture Sensitivity Level (MSL) difference between substitutes?

A: ASCO-2.000MHZ-EK-T and ASCO-2.000MHZ-EK-T3 have MSL listed as Not Applicable. SG-8018CG 2.0000M-TJHSA0 has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
