Key Parameters

Substitute Part Grouping Explanation

The substitute part SXO53C3C481-27.000M from Suntsu Electronics, Inc. is classified as a direct equivalent based on the following critical parameters:

• Identical frequency specification: 27 MHz
• Matching output type: CMOS
• Identical supply voltage: 3.3V
• Matching frequency stability: ±25ppm
• Identical operating temperature range: -40°C to 85°C
• Matching function: Enable/Disable capability
• Identical package type: 4-SMD, No Lead
• Identical package dimensions: 5.00mm x 3.20mm
• Identical RoHS3 compliance status
• Identical ECCN and HTSUS classifications

The substitute part maintains electrical and mechanical compatibility with the primary part across all specified parameters. Both parts are Active in production status and meet the same regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FD2700042 and SXO53C3C481-27.000M are Active production parts with ROHS3 compliance and identical regulatory classifications. The FD2700042 offers 1077 units in current inventory, while the SXO53C3C481-27.000M provides 2393 units in stock. Selection between these parts should be based on availability requirements and supply chain considerations. The Suntsu substitute exhibits a maximum height of 1.40mm compared to 1.30mm for the Diodes part, and a maximum supply current of 16mA versus 15mA. These minor variations remain within acceptable tolerances for applications designed to the FD2700042 specification. Both parts maintain identical electrical performance across frequency, stability, output type, and operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the SXO53C3C481-27.000M be used as a direct replacement for the FD2700042?
