Engineering Selection Recommendations

7C-40.000MBE-T (TXC CORPORATION)

This part is a parametric equivalent manufactured by TXC CORPORATION, the same manufacturer as the main part 7C40000067. All electrical and mechanical parameters are identical. The primary difference is packaging format: 7C-40.000MBE-T is supplied in Tape & Reel (TR) format, whereas the main part packaging is not specified. Both parts maintain RoHS Compliance and MSL 1 (Unlimited) rating. Current supply specification is provided at 30mA maximum. This substitute is suitable for applications where tape and reel packaging is preferred for automated assembly processes.

SXO53C3A481-40.000M (Suntsu Electronics, Inc.)

This part is a direct manufacturer equivalent from Suntsu Electronics, Inc., maintaining all critical electrical and mechanical parameters. The oscillator frequency, output type, supply voltage, enable/disable function, frequency stability, operating temperature range, and physical dimensions are identical to the main part. The current supply specification is 25mA maximum, which is lower than the TXC equivalent. This part is ROHS3 Compliant and supplied in Bulk packaging format. Selection of this substitute is appropriate when Suntsu Electronics supply chain availability or bulk packaging requirements are prioritized.

Both substitute parts are Active in product status and maintain full functional and mechanical compatibility with the 7C40000067 in circuit applications.

Frequently Asked Questions (FAQ)

Q1: Can 7C-40.000MBE-T be used as a direct replacement for 7C40000067?

A: Yes. Both parts are manufactured by TXC CORPORATION and maintain identical electrical specifications (40 MHz frequency, 3.3V supply, CMOS output, Enable/Disable function, ±50ppm stability, -40°C ~ 85°C operating range) and mechanical specifications (4-SMD No Lead package, 5.00mm x 3.20mm dimensions, 1.40mm maximum height). The difference is packaging format: 7C-40.000MBE-T is supplied in Tape & Reel format. Both are RoHS Compliant with MSL 1 (Unlimited).

Q2: Can SXO53C3A481-40.000M be used as a direct replacement for 7C40000067?

A: Yes. This Suntsu Electronics part maintains all critical electrical and mechanical parameters: 40 MHz frequency, 3.3V supply, CMOS output, Enable/Disable function, ±50ppm stability, -40°C ~ 85°C operating range, and identical 4-SMD No Lead package with 5.00mm x 3.20mm dimensions and 1.40mm maximum height. The part is ROHS3 Compliant and supplied in Bulk packaging.

Q3: What are the key differences between the substitute parts?

A: The primary differences are manufacturer (TXC CORPORATION vs. Suntsu Electronics), packaging format (Tape & Reel vs. Bulk), and maximum supply current specification (30mA vs. 25mA). All electrical and mechanical parameters remain equivalent.

Q4: Are there any compliance differences between these parts?

A: Both substitute parts are RoHS compliant. The main part and 7C-40.000MBE-T are RoHS Compliant, while SXO53C3A481-40.000M is ROHS3 Compliant. Both compliance levels are acceptable for modern electronic applications.

Q5: Does packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel vs. Bulk) affects only the supply and assembly process, not circuit performance. The electrical and mechanical specifications of the oscillator itself remain identical.

Q6: Which substitute should be selected for high-volume automated assembly?

A: 7C-40.000MBE-T in Tape & Reel format is optimized for automated pick-and-place assembly processes typical in high-volume production.

Q7: Which substitute should be selected for bulk procurement?

A: SXO53C3A481-40.000M is supplied in Bulk packaging format and may be preferred for applications where bulk procurement and manual assembly processes are utilized.
