FD2700035 Equivalent & Substitute Parts

Part Overview

The FD2700035 is a 27 MHz crystal oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FD series. This CMOS oscillator operates at 3.3V with Enable/Disable functionality in a 4-SMD, No Lead package. The device is actively produced and widely used in applications requiring precise 27 MHz frequency generation with low power consumption.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the allowed parameter ranges for this oscillator category.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the FD2700035 is determined by strict equivalence in the following parameters:

• Frequency: 27 MHz (exact match required)
• Output: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Package: 4-SMD, No Lead with matching footprint dimensions (5.00mm x 3.20mm)
• Compliance: ROHS3 Compliant

Variations in frequency stability, operating temperature range, and maximum supply current are permitted within the allowed electrical specifications for this product category, provided the core functional parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance. Selection between FD2700035, FD2700042, and SXO53C3A271-27.000M depends on application-specific requirements:

FD2700042 offers improved frequency stability (±25ppm versus ±50ppm) and extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C), making it suitable for applications requiring tighter tolerance or wider temperature operation.

SXO53C3A271-27.000M provides equivalent frequency stability and operating temperature to FD2700035 with slightly higher maximum supply current (16mA versus 15mA) and marginally greater seated height (1.40mm versus 1.30mm).

All parts are mechanically compatible with identical footprint dimensions and mounting type.

Frequently Asked Questions (FAQ)

Q: Can FD2700042 replace FD2700035 in existing designs?

A: Yes. FD2700042 maintains identical frequency, output type, supply voltage, function, and package specifications. The improved frequency stability and extended temperature range of FD2700042 are compatible with applications designed for FD2700035.

Q: What are the mechanical compatibility considerations?

A: All three parts use 4-SMD, No Lead packages with 5.00mm x 3.20mm footprints. SXO53C3A271-27.000M has a maximum seated height of 1.40mm compared to 1.30mm for the Diodes Incorporated parts. Verify clearance in applications with height constraints.

Q: Are there differences in disable mode current consumption?

A: FD2700035 and FD2700042 both specify 10µA maximum disable current. SXO53C3A271-27.000M does not provide this specification in the available data.

Q: Which part should be selected for high-temperature applications?

A: FD2700042 supports -40°C ~ 85°C operating temperature, compared to -20°C ~ 70°C for FD2700035 and SXO53C3A271-27.000M. Select FD2700042 for applications requiring extended high-temperature operation.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).
