Substitute Part Grouping Explanation

The 416F40611CDT has one parametric equivalent substitute: 416F40611CDR. Substitution is valid based on identical electrical and mechanical specifications across all critical parameters:

Key Parameters for Substitution Validity:

• Frequency: 40.61 MHz (exact match)
• Frequency Stability: ±10ppm (exact match)
• Load Capacitance: 18pF (exact match)
• ESR: 60 Ohms (exact match)
• Operating Mode: Fundamental (exact match)
• Operating Temperature Range: -20°C to 70°C (exact match)
• Package / Case: 4-SMD, No Lead (exact match)
• Physical Dimensions: 0.063" L x 0.047" W, 0.018" height (exact match)
• RoHS and REACH Compliance: Identical

The primary distinction between these parts is packaging format and product status, not electrical or mechanical performance.

Engineering Selection Recommendations

The 416F40611CDR is the direct parametric equivalent for the 416F40611CDT. Selection between these parts should be based on:

Product Status: The 416F40611CDR maintains active status with the manufacturer, ensuring long-term availability and supply chain stability. The 416F40611CDT is discontinued at DiGi Electronics, making it unsuitable for new designs or sustained production.

Compliance: Both parts maintain identical ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

Packaging Consideration: The 416F40611CDR is supplied in Tape & Reel format, standard for automated assembly processes. Packaging format does not affect electrical or mechanical performance.

For new designs, production ramp-up, or long-term supply requirements, 416F40611CDR is the appropriate selection. Existing inventory of 416F40611CDT may be used for current production until depletion, with transition to 416F40611CDR for continuity.

Frequently Asked Questions (FAQ)

Q: Are 416F40611CDT and 416F40611CDR electrically interchangeable?

A: Yes. Both parts have identical frequency (40.61 MHz), frequency stability (±10ppm), load capacitance (18pF), ESR (60 Ohms), operating mode (Fundamental), and temperature range (-20°C to 70°C). No circuit modifications are required.

Q: What is the difference between these two part numbers?
