Substitute Part Grouping Explanation

Substitute parts for the TYJABCSANF-16.367667 are qualified based on the following critical parameters that must remain constant:

Frequency: 16.367667 MHz (exact match required)
Type: VCTCXO (voltage-controlled temperature-compensated)
Output: Clipped Sine Wave
Frequency Stability: ±1ppm
Operating Temperature: -20°C ~ 70°C
Current - Supply (Max): 2mA
Package / Case: 4-SMD, No Lead
Size / Dimension: 0.098" L x 0.079" W (2.50mm x 2.00mm)

Engineering Selection Recommendations

For applications currently using the obsolete TYJABCSANF-16.367667, the CTS-Frequency Controls 520 series provides direct functional equivalents with active product status and full compliance certifications.

Primary Equivalent: 520N10CA16M3677 is the parametric equivalent, matching the original 2.5V supply voltage specification of the TYJABCSANF-16.367667. This part maintains identical electrical and mechanical characteristics while offering active manufacturing status and improved supply chain availability.

Voltage-Specific Alternatives: When circuit design permits alternative supply voltages, the 520M10CA16M3677 (1.8V), 520T10CA16M3677 (2.8V), and 520R10CA16M3677 (3V) provide equivalent VCTCXO performance within their respective voltage domains. All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical package geometry.

Frequently Asked Questions (FAQ)

Q: Can I use 520N10CA16M3677 as a direct replacement for TYJABCSANF-16.367667?

A: Yes. The 520N10CA16M3677 is a parametric equivalent with matching 2.5V supply voltage, identical frequency, output type, stability, temperature range, current consumption, and package specifications. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the four CTS-Frequency Controls substitute parts?

A: The four parts differ only in supply voltage: 520M10CA16M3677 operates at 1.8V, 520N10CA16M3677 at 2.5V, 520T10CA16M3677 at 2.8V, and 520R10CA16M3677 at 3V. All other parameters including frequency, stability, temperature range, current consumption, and package dimensions are identical.

Q: Can I substitute a lower voltage part (1.8V) for the original 2.5V specification?

A: Substitution is only valid if your circuit design supports the alternative voltage. The 520M10CA16M3677 (1.8V) maintains all electrical performance parameters but requires confirmation that the application power supply and signal processing circuits can operate at 1.8V.

Q: Are all substitute parts in active production?

A: Yes. All four CTS-Frequency Controls 520 series parts (520M10CA16M3677, 520N10CA16M3677, 520T10CA16M3677, 520R10CA16M3677) have active product status, unlike the obsolete TYJABCSANF-16.367667.

Q: Do the substitute parts have the same package footprint?

A: Yes. All substitute parts use the 4-SMD, No Lead package with identical dimensions of 0.098" L x 0.079" W (2.50mm x 2.00mm) and maximum seated height of 0.031" (0.80mm). PCB layout and assembly processes remain unchanged.

Q: Are there any compliance differences between the original and substitute parts?

A: No. Both the original TYJABCSANF-16.367667 and all CTS-Frequency Controls 520 series substitutes are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.
