Key Parameters

Substitute Part Grouping Explanation

Substitution of the 416F520X2IST is determined by strict equivalence across the following critical parameters:

• Frequency: 52 MHz (exact match required)
• Frequency Stability: ±20ppm (exact match required)
• Frequency Tolerance: ±15ppm (exact match required)
• ESR: 60 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 0.063" L x 0.047" W, 0.018" max height (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (exact match required)

The 416F520X2ISR qualifies as a parametric equivalent substitute based on identical electrical and mechanical specifications. The primary distinction is packaging format and product status.

Frequently Asked Questions (FAQ)

Q: Can the 416F520X2ISR be used as a direct replacement for the 416F520X2IST?

A: Yes. The 416F520X2ISR is a parametric equivalent with identical frequency (52 MHz), frequency stability (±20ppm), frequency tolerance (±15ppm), ESR (60 Ohms), operating temperature range (-40°C to 85°C), and physical dimensions (0.063" L x 0.047" W, 0.018" max height). Both use the 4-SMD, No Lead package format.

Q: What is the difference between the 416F520X2IST and 416F520X2ISR?

A: The primary differences are product status and packaging format. The 416F520X2IST is discontinued at DiGi Electronics and supplied in bulk packaging, while the 416F520X2ISR is active and supplied in Tape & Reel (TR) format. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8541.60.0060.

Q: Is the Tape & Reel packaging of the 416F520X2ISR compatible with my assembly process?

A: Tape & Reel packaging is standard for automated surface mount assembly. If your process requires bulk packaging, component reeling services are available through distribution channels. The physical dimensions and electrical characteristics remain unchanged.

Q: What is the load capacitance specification for these crystals?

A: Both parts are specified as Series load capacitance type, consistent with the 416 series crystal design from CTS-Frequency Controls.
