TYJADCSANF-16.367667 VCTCXO Oscillator Equivalent & Substitute Parts

Part Overview

The TYJADCSANF-16.367667 is a 16.367667 MHz voltage-controlled temperature-compensated crystal oscillator (VCTCXO) manufactured by Taitien. This clipped sine wave oscillator operates at 2.5V supply voltage with ±2.5ppm frequency stability across the -20°C to 70°C temperature range. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitute parts for the TYJADCSANF-16.367667 are qualified based on the following critical parameters that determine functional compatibility:

Frequency: Must be exactly 16.367667 MHz
Type: Must be VCTCXO
Output: Must be Clipped Sine Wave
Frequency Stability: Must be ±2.5ppm
Operating Temperature Range: Must be -20°C ~ 70°C
Current - Supply (Max): Must be 2mA

Engineering Selection Recommendations

All four CTS-Frequency Controls substitutes (520M25CA16M3677, 520R25CA16M3677, 520T25CA16M3677, 520N25CA16M3677) are active production parts with full ROHS3 compliance and REACH unaffected status. These parts maintain identical electrical performance specifications and physical package dimensions as the obsolete Taitien original.

For direct replacement in existing designs operating at 2.5V supply voltage, the 520N25CA16M3677 provides parametric equivalence with no circuit modifications required. This part is currently in active production with 998 units in stock.

For new designs or systems with flexible supply voltage requirements, the alternative voltage ratings (1.8V, 2.8V, 3V) offer design flexibility while maintaining all core VCTCXO performance characteristics. Selection should be based on the actual supply voltage available in the target application circuit.

Frequently Asked Questions (FAQ)

Q: Can the 520M25CA16M3677 (1.8V) be used as a direct replacement for the TYJADCSANF-16.367667 (2.5V)?

A: The 520M25CA16M3677 is electrically and mechanically compatible but operates at a different supply voltage. Direct substitution requires the application circuit to provide 1.8V instead of 2.5V. If the circuit is designed for 2.5V operation, use the 520N25CA16M3677 instead.

Q: Are all substitute parts pin-compatible with the original TYJADCSANF-16.367667?

A: Yes. All substitute parts use the identical 4-SMD, No Lead package with matching physical dimensions (0.098" L x 0.079" W, 0.031" max height). PCB footprints are directly compatible.

Q: What is the difference between the substitute parts?

A: The four substitute parts are identical except for supply voltage rating: 520M25CA16M3677 (1.8V), 520R25CA16M3677 (3V), 520T25CA16M3677 (2.8V), and 520N25CA16M3677 (2.5V). All maintain ±2.5ppm frequency stability and 2mA maximum supply current.

Q: Are the substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: Which substitute part should I select for a new design?

A: Select based on your application's supply voltage. For 2.5V systems, use 520N25CA16M3677. For other voltage requirements, select the corresponding part: 520M25CA16M3677 (1.8V), 520T25CA16M3677 (2.8V), or 520R25CA16M3677 (3V).
