416F38433IST Crystal Equivalent & Substitute Parts

Part Overview

The 416F38433IST is a 38.4 MHz crystal oscillator manufactured by CTS-Frequency Controls, designed for surface mount applications in a 4-SMD, No Lead package. This component operates at a fundamental frequency with ±30ppm stability across the -40°C to 85°C temperature range and features 60 Ohms equivalent series resistance (ESR).

The 416F38433IST is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this frequency specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 416F38433IST is determined by strict equivalence across the following critical parameters:

• Frequency: 38.4 MHz (exact match required)
• Frequency Stability: ±30ppm (tolerance specification)
• ESR: 60 Ohms (circuit impedance matching)
• Operating Mode: Fundamental (frequency generation method)
• Operating Temperature Range: -40°C to 85°C (thermal performance envelope)
• Package / Case: 4-SMD, No Lead (physical and electrical footprint)
• Load Capacitance: Series (circuit configuration compatibility)

The 416F38433ISR meets all these critical parameters and qualifies as a direct parametric equivalent. The primary distinction between these parts is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The 416F38433ISR is the direct parametric equivalent for the discontinued 416F38433IST. Both parts are manufactured by CTS-Frequency Controls and share identical electrical and mechanical specifications across all critical parameters.

The 416F38433ISR maintains active product status and is available in Tape & Reel packaging format, making it suitable for production environments requiring automated assembly processes. Both parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

Selection between these parts depends on packaging requirements and supply availability. The 416F38433ISR is the recommended choice for new designs and ongoing production due to its active status and standard distribution format.

Frequently Asked Questions (FAQ)

Q: Can the 416F38433ISR directly replace the 416F38433IST in existing designs?
