FD2700033 Equivalent & Substitute Parts

Part Overview

The FD2700033 is a 27 MHz XO (Standard) CMOS Oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FD series. This surface mount crystal oscillator operates at 3.3V with Enable/Disable functionality and is housed in a 4-SMD, No Lead package. The component is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where the original part becomes unavailable or inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

Substitute parts for the FD2700033 are qualified based on the following critical parameters:

• Frequency: 27 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 5.00mm x 3.20mm (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The FD2700042 (Diodes Incorporated) qualifies as a manufacturer-recommended substitute with identical electrical specifications and package configuration. The SXO53C3C271-27.000M (Suntsu Electronics, Inc.) qualifies as a direct manufacturer alternative with matching core parameters. Both parts maintain compatibility with applications designed for the FD2700033.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, qualifying them for use in applications requiring regulatory adherence. The FD2700042 is the manufacturer-recommended substitute from Diodes Incorporated, offering extended operating temperature range (-40°C ~ 85°C) compared to the FD2700033 (-20°C ~ 70°C), providing broader thermal performance for demanding environments. The SXO53C3C271-27.000M from Suntsu Electronics, Inc. provides an alternative from a different manufacturer with identical core electrical specifications and matching package footprint. Selection between these parts depends on application temperature requirements, supply chain availability, and manufacturer preference within the design specification.

Frequently Asked Questions (FAQ)

Q: Can the FD2700042 replace the FD2700033 in all applications?

A: The FD2700042 is electrically and mechanically compatible with the FD2700033. The primary difference is the extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C). Applications operating within the original temperature range of -20°C ~ 70°C will function identically with either part.

Q: What are the physical compatibility considerations between these parts?

A: All three parts share identical package type (4-SMD, No Lead) and footprint dimensions (5.00mm x 3.20mm). The SXO53C3C271-27.000M has a maximum seated height of 1.40mm compared to 1.30mm for the FD2700033 and FD2700042. This 0.10mm difference must be evaluated against PCB clearance requirements and component placement constraints.

Q: Are there current consumption differences between these oscillators?

A: The FD2700033 and FD2700042 both specify maximum supply current of 15mA. The SXO53C3C271-27.000M specifies 16mA maximum supply current. This 1mA difference is negligible for most applications but should be considered in power-constrained designs.

Q: Do all parts meet the same compliance standards?

A: All three parts are ROHS3 compliant and carry EAR99 ECCN classification. All parts are classified under HTSUS code 8542.39.0001. Compliance requirements are equivalent across all substitute options.

Q: What is the substitution basis for these parts?

A: Substitution is based on matching frequency (27 MHz), output type (CMOS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±25ppm), package configuration (4-SMD, No Lead), and physical footprint (5.00mm x 3.20mm). All three parts meet these criteria.
