ASE-48.000MHZ-C-T3 Equivalent & Substitute Parts

Part Overview

The ASE-48.000MHZ-C-T3 is a 48 MHz crystal oscillator manufactured by Abracon LLC, designed for applications requiring a standard XO (crystal oscillator) with CMOS output and enable/disable functionality. This component operates at 3.3V supply voltage and is housed in a compact 4-SMD, No Lead package measuring 3.20mm x 2.50mm. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASE-48.000MHZ-C-T3 are qualified based on the following critical parameters that must remain constant:

• Frequency: 48 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±50ppm
• Operating Temperature Range: -10°C ~ 70°C
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 3.20mm x 2.50mm
• Mounting Type: Surface Mount

The identified substitute parts maintain electrical equivalence across all specified parameters. Variations in current consumption, seated height, and packaging format (tape & reel vs. bulk) do not affect functional interchangeability in circuit applications where these specifications are met.

Parameter Comparison

Engineering Selection Recommendations

All three oscillators meet the core electrical and mechanical requirements for direct substitution. Selection should be based on the following factors:

ASE-48.000MHZ-C-T3 (Abracon LLC): Active product status with ROHS3 compliance and REACH unaffected designation. Current supply maximum of 19mA. Seated height of 1.20mm. Suitable for applications where Abracon supply chain preference is established.

7X-48.000MBB-T (FTS): Active product status with RoHS compliance. Lowest current supply maximum at 10mA, providing potential power efficiency advantage. Lowest seated height at 1.10mm, beneficial for space-constrained PCB layouts. Supplied in tape & reel packaging format. REACH status available upon request.

SXO32C3A171-48.000M (Suntsu Electronics): Active product status with ROHS3 compliance and REACH unaffected designation. Current supply maximum of 17mA. Seated height of 1.20mm. Supplied in bulk packaging format. Equivalent compliance profile to the primary part.

Frequently Asked Questions (FAQ)

Q: Can these parts be used interchangeably on the same PCB? A: Yes. All three oscillators share identical electrical specifications (48 MHz, CMOS output, 3.3V supply, ±50ppm stability, -10°C to 70°C operating range) and identical package dimensions (3.20mm x 2.50mm, 4-SMD No Lead). PCB footprints and circuit connections are compatible.

Q: What is the significance of the current supply differences (19mA, 10mA, 17mA)? A: Current consumption variations reflect different internal circuit designs while maintaining the same output specifications. The 7X-48.000MBB-T offers the lowest maximum current draw, which may reduce power dissipation in battery-powered or power-sensitive applications. Selection should align with system power budget requirements.

Q: Does the seated height difference (1.20mm vs. 1.10mm) affect compatibility? A: No. The 0.10mm height variation is within typical PCB assembly tolerances and does not affect electrical performance or mechanical fit. The FTS part's lower profile may provide marginal benefit in ultra-compact designs, but all three parts are mechanically compatible with standard 4-SMD No Lead footprints.

Q: What is the difference between tape & reel and bulk packaging? A: Tape & reel packaging (7X-48.000MBB-T) is optimized for automated assembly lines with continuous feeding capability. Bulk packaging (SXO32C3A171-48.000M) is suitable for manual assembly or lower-volume production. Both formats contain equivalent components; packaging choice depends on manufacturing process requirements.

Q: Are all parts RoHS compliant? A: Yes. The ASE-48.000MHZ-C-T3 and SXO32C3A171-48.000M carry ROHS3 certification. The 7X-48.000MBB-T is RoHS compliant with REACH status available upon request from the manufacturer.

Q: Can I mix these parts within a single production run? A: Yes, provided your quality and traceability procedures permit multi-source component usage. All three parts meet identical electrical and mechanical specifications. Verify internal procurement and documentation requirements before implementing mixed-source strategies.
