FD1200030 Equivalent & Substitute Parts

Part Overview

The FD1200030 is a 12 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, housed in a 4-SMD, No Lead package. The device is currently active in production with 939 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility across multiple manufacturers is needed while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FD1200030 is determined by the following mandatory parameters:

• Frequency: 12 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: ±50ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

All three substitute parts meet these criteria. Variations in current consumption, physical dimensions within the 4-SMD No Lead envelope, and height specifications do not preclude substitution, as these parameters fall within acceptable tolerances for this component category.

Parameter Comparison

Engineering Selection Recommendations

LFSPXO009585BULK (IQD Frequency Products): This substitute offers the lowest maximum supply current at 4.5mA and the lowest seated height at 0.95mm. The part is active in production with 1127 units in stock. It is suitable for applications where power consumption and PCB clearance are design constraints.

LFSPXO026152BULK (IQD Frequency Products): This part is discontinued at DiGi Electronics, limiting its long-term availability. While it meets all electrical and mechanical substitution criteria, its discontinued status makes it unsuitable for new designs or applications requiring sustained supply chain support.

SXO53C3A481-12.000M (Suntsu Electronics, Inc.): This substitute maintains dimensional compatibility with the FD1200030 (identical length and width) and is active in production with the highest inventory level at 3081 units. The maximum supply current of 16mA and seated height of 1.40mm are within acceptable tolerances for this component category.

For new designs and applications requiring long-term availability, LFSPXO009585BULK or SXO53C3A481-12.000M are the preferred selections. Both manufacturers maintain active production status and adequate inventory levels.

Frequently Asked Questions (FAQ)

Q: Can LFSPXO009585BULK be used as a direct replacement for FD1200030?

A: Yes. Both parts share identical electrical specifications (12 MHz, CMOS output, 3.3V supply, Enable/Disable function, ±50ppm stability, -40°C to 85°C operating range) and package type (4-SMD, No Lead). The lower supply current and reduced height are compatible with standard PCB designs.

Q: Why is LFSPXO026152BULK listed as a substitute if it is discontinued?

A: LFSPXO026152BULK meets all mandatory substitution criteria and may be available through secondary market channels or existing inventory. However, it is not recommended for new designs due to its discontinued status at primary distributors.

Q: Are there physical compatibility concerns with the dimensional variations shown in the comparison table?

A: No. All substitute parts use the 4-SMD, No Lead package type. Dimensional variations (length, width, height) fall within the tolerance envelope for this package category and do not affect PCB footprint compatibility or circuit performance.

Q: What is the significance of the current consumption differences between the main part and substitutes?

A: Current consumption variations (4.5mA to 20mA maximum) reflect different internal circuit designs but do not affect functional compatibility. Selection should be based on application power budget requirements. The LFSPXO009585BULK offers the lowest consumption for power-sensitive applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts carry ROHS3 Compliant certification, matching the compliance status of the FD1200030.
