416F44033CDT Crystal Oscillator - Equivalent & Substitute Parts

Part Overview

The 416F44033CDT is a 44 MHz crystal oscillator manufactured by CTS-Frequency Controls, designed for surface mount applications requiring fundamental mode operation. This component is discontinued at DiGi Electronics, necessitating identification of equivalent substitute parts for ongoing production and maintenance applications. The part operates across the -20°C to 70°C temperature range with ±30ppm frequency stability, suitable for precision timing applications in industrial and commercial electronics.

Substitute Part Grouping Explanation

Substitution of the 416F44033CDT is determined by strict equivalence across electrical and mechanical parameters. The primary substitute, 416F44033CDR, maintains identical specifications across all critical parameters: 44 MHz frequency, ±30ppm stability, 18pF load capacitance, 60 Ohms ESR, fundamental operating mode, and identical physical dimensions and package configuration. The distinction between these parts is packaging format only: the original part uses cut tape packaging, while the substitute uses Tape & Reel (TR) format. Both parts are manufactured by CTS-Frequency Controls within the same 416 series and comply with identical regulatory standards (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Parameter Comparison

Engineering Selection Recommendations

The 416F44033CDR serves as the direct parametric equivalent to the discontinued 416F44033CDT. Selection between these parts is determined by procurement and assembly requirements rather than electrical or mechanical performance. The 416F44033CDR maintains active product status with CTS-Frequency Controls, ensuring continued availability and supply chain stability. Both parts satisfy identical regulatory compliance requirements (ROHS3, REACH Unaffected, EAR99 classification) and carry equivalent moisture sensitivity ratings. The Tape & Reel packaging format of the 416F44033CDR is standard for high-volume automated assembly operations, while cut tape format is typically reserved for lower-volume or manual assembly scenarios. Component selection should be based on production volume requirements and existing assembly line capabilities.

Frequently Asked Questions (FAQ)

Q: Can the 416F44033CDR directly replace the 416F44033CDT in existing designs?

A: Yes. The 416F44033CDR is electrically and mechanically identical to the 416F44033CDT across all specified parameters, including frequency, stability, load capacitance, ESR, operating temperature range, and physical dimensions. The only difference is packaging format (Tape & Reel versus cut tape).

Q: What is the significance of the packaging format difference between these parts?

A: Packaging format affects supply chain logistics and assembly line compatibility. Tape & Reel (TR) format is optimized for automated pick-and-place assembly equipment, while cut tape format is used for manual or semi-automated handling. The electrical and mechanical performance of the crystal oscillator itself is unaffected by packaging format.

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

A: No. Both the 416F44033CDT and 416F44033CDR carry identical certifications: ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification. Moisture sensitivity level (MSL 1 - Unlimited) is identical for both parts.

Q: Why is the 416F44033CDT discontinued while the 416F44033CDR remains active?

A: Product discontinuation decisions are typically driven by market demand and supply chain optimization. The 416F44033CDR in Tape & Reel format aligns with modern automated assembly practices and represents the active product line offering from CTS-Frequency Controls for this specification.

Q: What parameters must remain constant for substitution compatibility?

A: Frequency (44 MHz), frequency stability (±30ppm), load capacitance (18pF), ESR (60 Ohms), operating mode (Fundamental), operating temperature range (-20°C to 70°C), package type (4-SMD, No Lead), and physical dimensions (0.063" L x 0.047" W, 0.018" max height) must all remain identical for direct substitution.
