Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACZ-32.768KBE-T are identified based on strict equivalence of the following critical parameters:

• Frequency: 32.768 kHz (exact match required)
• Output Configuration: CMOS output with enable/disable function
• Supply Voltage: 3.3V operation
• Frequency Stability: ±50ppm tolerance
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead
• Package Dimensions: 5.00mm x 3.20mm
• Mounting Type: Surface Mount

The TC50L3I32K7680 manufactured by CTS-Frequency Controls meets all these critical parameters and qualifies as a direct substitute. This part maintains functional and mechanical compatibility with the original ACZ-32.768KBE-T design.

Parameter Comparison

Engineering Selection Recommendations

The TC50L3I32K7680 is a qualified substitute for the ACZ-32.768KBE-T based on the following engineering criteria:

Functional Compatibility: Both parts operate at identical frequency (32.768 kHz), supply voltage (3.3V), and output configuration (CMOS with enable/disable). Frequency stability (±50ppm) and operating temperature range (-40°C ~ 85°C) are equivalent.

Mechanical Compatibility: Package type, dimensions (5.00mm x 3.20mm), and mounting type (Surface Mount, 4-SMD No Lead) are identical. The TC50L3I32K7680 seated height (1.30mm) is slightly lower than the ACZ-32.768KBE-T (1.40mm), which presents no compatibility issues for standard PCB layouts.

Compliance Status: The TC50L3I32K7680 is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. The ACZ-32.768KBE-T is RoHS Compliant. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Supply Chain Advantage: The TC50L3I32K7680 is classified as Active product status with 937 Pcs in stock, ensuring long-term availability compared to the obsolete ACZ-32.768KBE-T.

Power Consumption Benefit: The TC50L3I32K7680 operates at a maximum supply current of 3mA, compared to 20mA for the ACZ-32.768KBE-T, providing improved power efficiency in battery-powered or low-power applications.

Frequently Asked Questions (FAQ)

Q: Can the TC50L3I32K7680 be used as a direct replacement for the ACZ-32.768KBE-T without PCB modifications?

A: Yes. Both parts share identical package type (4-SMD, No Lead), dimensions (5.00mm x 3.20mm), and pin configuration for enable/disable CMOS output at 3.3V. The TC50L3I32K7680 seated height (1.30mm) is within standard PCB assembly tolerances relative to the ACZ-32.768KBE-T (1.40mm). No PCB layout changes are required.

Q: What are the key electrical differences between these parts?

A: The primary electrical difference is maximum supply current: the TC50L3I32K7680 draws 3mA maximum, while the ACZ-32.768KBE-T draws 20mA maximum. All other electrical parameters—frequency, stability, voltage, output type, and temperature range—are identical.

Q: Are there any compliance or regulatory differences?

A: The TC50L3I32K7680 meets ROHS3 Compliant and REACH Unaffected standards, representing current regulatory compliance. The ACZ-32.768KBE-T is RoHS Compliant. Both parts carry identical moisture sensitivity level (MSL 1, Unlimited) and ECCN/HTSUS classifications.

Q: Why is the ACZ-32.768KBE-T classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by TXC CORPORATION. The TC50L3I32K7680, classified as Active, represents the current production alternative with equivalent functionality and improved power efficiency.

Q: What packaging options are available for the TC50L3I32K7680?

A: The TC50L3I32K7680 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Verify packaging requirements for your procurement specifications.
