CE3392-40.000 Equivalent & Substitute Parts

Part Overview

The CE3392-40.000 is a 40 MHz XO (Standard) HCMOS oscillator manufactured by Crystek Corporation. This surface mount crystal oscillator operates at 3.3V with enable/disable functionality, housed in a 4-SMD, No Lead package. The device is Active status and ROHS3 compliant, making it suitable for applications requiring stable frequency generation with low power consumption. Substitute parts are identified for inventory availability, supply chain continuity, or specific application requirements where equivalent electrical and mechanical parameters are maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CE3392-40.000 are qualified based on the following critical parameters:

• Frequency: 40 MHz (exact match required)
• Output Type: HCMOS (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 Status: ROHS3 Compliant (exact match required)

All identified substitute parts meet these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) and maximum supply current remain within acceptable tolerances for direct substitution in standard PCB layouts and circuit designs.

Parameter Comparison

Engineering Selection Recommendations

All three oscillators are Active status products with ROHS3 compliance and REACH Unaffected designation, meeting current regulatory requirements for electronic component procurement.

The ECS-3953M-400-BN-TR offers the lowest profile height at 0.055" (1.40mm) and maintains identical electrical specifications, making it suitable for space-constrained applications. The LFSPXO017885 provides a 5mA reduction in maximum supply current compared to the primary part, offering potential power efficiency benefits in battery-operated or power-sensitive designs.

Physical dimension variations across all three parts remain within standard PCB layout tolerances for 4-SMD, No Lead packages. Selection should be based on inventory availability, lead time requirements, and specific application constraints regarding board height or power consumption.

Frequently Asked Questions (FAQ)

Q: Can ECS-3953M-400-BN-TR be used as a direct replacement for CE3392-40.000?

A: Yes. Both parts share identical electrical specifications (40 MHz, HCMOS output, 3.3V supply, ±50ppm stability, -40°C to 85°C operating range) and package type (4-SMD, No Lead). Physical dimensions differ slightly (7.00mm x 5.00mm vs. 7.20mm x 5.20mm), but remain within standard PCB layout tolerances for this package category.

Q: What is the difference in current consumption between these parts?

A: The CE3392-40.000 and ECS-3953M-400-BN-TR both specify 25mA maximum supply current. The LFSPXO017885 specifies 20mA maximum supply current, representing a 5mA reduction. This difference may be relevant for power-constrained applications.

Q: Are there height considerations for PCB assembly?

A: Yes. The CE3392-40.000 has a maximum seated height of 0.071" (1.80mm), the ECS-3953M-400-BN-TR is 0.067" (1.70mm), and the LFSPXO017885 is 0.055" (1.40mm). Applications with strict height limitations should specify the LFSPXO017885.

Q: Do all parts meet the same compliance standards?

A: All three parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 under export control regulations. All share the same HTSUS code (8542.39.0001).

Q: What is the moisture sensitivity difference between parts?

A: The CE3392-40.000 and ECS-3953M-400-BN-TR specify MSL 1 (Unlimited). The LFSPXO017885 specifies MSL as Not Applicable, indicating different moisture handling requirements during storage and assembly.
