TC-12.352MBD-T Equivalent & Substitute Parts

Part Overview

The TC-12.352MBD-T is a 12.352 MHz MEMS-based XO (Standard) oscillator manufactured by TXC CORPORATION. This component operates at 3.3V with CMOS output, Enable/Disable function, and is housed in a 4-SMD, No Lead package. The part is classified as Obsolete, making identification of equivalent and substitute components essential for ongoing system support and procurement planning. Substitute parts must maintain functional compatibility while meeting the same electrical and mechanical specifications required for direct replacement or system integration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TC-12.352MBD-T are identified based on strict parameter matching across the following critical criteria:

Mandatory Matching Parameters:

• Frequency: 12.352 MHz (exact match required)
• Output Type: CMOS
• Function: Enable/Disable capability
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Physical Dimensions: 3.20mm x 2.50mm footprint
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Supply Voltage: Substitute must support 3.3V operation (wider voltage ranges acceptable if 3.3V is within specification)
• Package Configuration: 4-SMD or 6-SMD formats acceptable if pin-compatible
• Maximum Height: Substitute height must not exceed 0.80mm seated height for standard PCB clearance
• Supply Current: Substitute current draw must not exceed system power budget constraints
• Base Resonator Technology: MEMS or Crystal resonator types both acceptable if all electrical parameters match

Two substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

7X-12.352MBD-T (TXC CORPORATION)

This substitute is an Active product from the same manufacturer (TXC CORPORATION) and represents a direct functional equivalent. It maintains identical frequency, stability, output type, and operating temperature specifications. The 7X series uses a Crystal resonator instead of MEMS technology but delivers equivalent electrical performance. Supply current is reduced to 15mA, providing improved power efficiency compared to the main part. The seated height increases to 1.10mm, which may require PCB layout verification for clearance-sensitive applications. RoHS Compliance certification is provided. This part is recommended for applications where component availability and manufacturer continuity are prioritized.

ASEMPC-12.352MHZ-LR-T (Abracon LLC)

This substitute is an Active product from Abracon LLC and maintains MEMS resonator technology identical to the main part. All critical electrical parameters match: frequency, stability, output type, and operating temperature. The supply voltage range (2.25V ~ 3.6V) provides broader compatibility than the fixed 3.3V specification. The 6-SMD package configuration differs from the 4-SMD main part, requiring PCB footprint verification. Maximum seated height is 0.90mm, within acceptable clearance margins. Supply current is 35mA with 26mA in Disable mode. ROHS3 and REACH compliance certifications are provided. This part is recommended for applications requiring extended voltage tolerance and MEMS-based resonator technology.

Frequently Asked Questions (FAQ)

Q: Can the 7X-12.352MBD-T be used as a direct replacement for the TC-12.352MBD-T?

A: The 7X-12.352MBD-T is functionally equivalent for all electrical specifications. However, the seated height increases from 0.80mm to 1.10mm. PCB layout must be verified to confirm adequate clearance above the component. Pin configuration and footprint remain identical (4-SMD, No Lead).

Q: What is the primary difference between the two substitute parts?

A: The 7X-12.352MBD-T uses Crystal resonator technology with lower supply current (15mA), while the ASEMPC-12.352MHZ-LR-T uses MEMS technology with higher supply current (35mA) but broader voltage tolerance (2.25V ~ 3.6V). The ASEMPC uses a 6-SMD package versus the 4-SMD configuration of both other parts.

Q: Is the ASEMPC-12.352MHZ-LR-T compatible with 3.3V systems?

A: Yes. The ASEMPC supply voltage range of 2.25V ~ 3.6V includes 3.3V operation. The part is fully compatible with 3.3V systems.

Q: Does the 6-SMD package of the ASEMPC-12.352MHZ-LR-T require PCB redesign?

A: The physical footprint dimensions (3.20mm x 2.50mm) remain identical to the main part. However, the 6-SMD package configuration differs from the 4-SMD main part. PCB footprint verification is required to confirm pad layout compatibility before implementation.

Q: Which substitute part has the lowest power consumption?

A: The 7X-12.352MBD-T has the lowest maximum supply current at 15mA, compared to 25mA for the main part and 35mA for the ASEMPC substitute.

Q: Are both substitute parts RoHS compliant?

A: Yes. The 7X-12.352MBD-T is RoHS Compliant. The ASEMPC-12.352MHZ-LR-T is ROHS3 Compliant. Both meet current environmental compliance requirements.

Q: What is the impact of the height difference between substitutes?

A: The 7X-12.352MBD-T seated height is 1.10mm (0.30mm taller than the main part). The ASEMPC-12.352MHZ-LR-T seated height is 0.90mm (0.10mm taller than the main part). Applications with tight vertical clearance constraints must verify PCB layout compatibility.
