CE3292-12.288 Equivalent & Substitute Parts

Part Overview

The CE3292-12.288 is a 12.288 MHz XO (Standard) crystal oscillator manufactured by Crystek Corporation. This surface mount oscillator provides HCMOS and TTL output with 5V supply voltage and enable/disable functionality. The device is designed for applications requiring precise frequency generation with ±50ppm stability across the -40°C to 85°C operating temperature range. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, substitute parts may be required for supply chain optimization, inventory management, or regional availability considerations.

Substitute Part Grouping Explanation

Substitution eligibility for the CE3292-12.288 is determined by strict equivalence across the following critical parameters:

• Frequency: 12.288 MHz (exact match required)
• Output Configuration: HCMOS, TTL (exact match required)
• Supply Voltage: 5V (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Function: Enable/Disable (exact match required)
• Package/Case: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The CB3-3I-12M288000 from CTS-Frequency Controls meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the CE3292-12.288 and CB3-3I-12M288000 are active products with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on supply chain availability and inventory requirements. The CB3-3I-12M288000 demonstrates lower maximum supply current (25mA versus 60mA), which may provide operational advantages in power-constrained applications. Both devices carry EAR99 export classification and are suitable for direct substitution in 12.288 MHz oscillator applications requiring HCMOS/TTL output with enable/disable control.

Frequently Asked Questions (FAQ)

Q: Can the CB3-3I-12M288000 be used as a direct replacement for the CE3292-12.288?

A: Yes. Both parts meet identical specifications for frequency, output type, supply voltage, frequency stability, operating temperature range, function, package type, and compliance ratings. The parts are electrically and mechanically compatible for direct substitution.

Q: What are the physical differences between these parts?

A: The CB3-3I-12M288000 has slightly smaller footprint dimensions (7.00mm x 5.00mm versus 7.20mm x 5.20mm). Both parts maintain the same maximum seated height of 1.80mm and use identical 4-SMD, No Lead packaging. PCB layout verification is recommended to confirm fit within existing design constraints.

Q: Why does the CB3-3I-12M288000 have lower maximum supply current?

A: The CB3-3I-12M288000 specifies 25mA maximum supply current compared to 60mA for the CE3292-12.288. This difference reflects manufacturer design optimization and does not affect functional compatibility. Both parts deliver identical output specifications and frequency stability.

Q: Are there any compliance or certification differences?

A: No. Both parts carry ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both devices.

Q: What is the enable/disable function specification?

A: Both parts provide enable/disable functionality for supply current control. The CB3-3I-12M288000 specifies maximum disable current of 10µA, enabling low-power standby operation.
