• Operating Temperature Range: FD2700036 (-20°C ~ 70°C) vs. FD2700042 (-40°C ~ 85°C) — FD2700042 provides extended temperature coverage
• Packaging: FD2700036 (tape/reel) vs. FD2700042 (bulk) — mechanical packaging format only

Parameter Comparison

Engineering Selection Recommendations

Both FD2700036 and FD2700042 are active production parts from Diodes Incorporated with ROHS3 compliance and identical regulatory status (REACH Unaffected, ECCN EAR99). Selection between these parts depends on application-specific requirements:

Select FD2700036 when:

• Tighter frequency stability (±20ppm) is required
• Operating environment is limited to -20°C ~ 70°C range
• Tape/reel packaging format is specified

Select FD2700042 when:

• Extended operating temperature range (-40°C ~ 85°C) is required
• Frequency stability of ±25ppm is acceptable
• Bulk packaging format is acceptable
• Higher inventory availability is needed (1077 units vs. 766 units)

Both parts are electrically and mechanically interchangeable for PCB layout, schematic design, and reflow soldering processes. No circuit modifications are required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can FD2700042 replace FD2700036 in existing designs? A: Yes. Both parts are pin-compatible, have identical package dimensions (5.00mm x 3.20mm), and share the same 4-SMD, No Lead footprint. No PCB redesign is required.

Q: What is the difference in frequency stability between these parts? A: FD2700036 provides ±20ppm stability, while FD2700042 provides ±25ppm stability. The 5ppm difference is within acceptable tolerance for most standard oscillator applications. Applications requiring tighter stability should specify FD2700036.

Q: Does the extended temperature range of FD2700042 affect performance? A: FD2700042 operates from -40°C ~ 85°C compared to FD2700036's -20°C ~ 70°C range. The extended range does not degrade performance within the FD2700036's original operating window. Applications requiring operation below -20°C or above 70°C must use FD2700042.

Q: Are there packaging differences between these parts? A: FD2700036 is supplied in tape/reel format, while FD2700042 is supplied in bulk packaging. Both contain identical components with no functional differences. Packaging selection depends on assembly process requirements and order quantities.

Q: Do both parts meet the same compliance standards? A: Yes. Both FD2700036 and FD2700042 are ROHS3 compliant, REACH unaffected, and classified as EAR99. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Which part should be used for new designs? A: Both parts are active in production. FD2700042 offers extended temperature coverage and higher inventory availability. FD2700036 provides tighter frequency stability. Selection should be based on specific application requirements.
