Substitute Part Grouping Explanation

Substitution of the 416F40011CDT is determined by strict equivalence across the following critical parameters:

• Frequency: 40 MHz (exact match required)
• Frequency Stability: ±10ppm (exact match required)
• Load Capacitance: 18pF (exact match required)
• ESR: 60 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -20°C to 70°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)

The substitute part 416F40011CDR meets all these criteria and is manufactured by the same supplier (CTS-Frequency Controls) within the same 416 series. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The 416F40011CDR is a direct electrical and mechanical equivalent to the 416F40011CDT. Both parts are manufactured by CTS-Frequency Controls and share identical electrical specifications, physical dimensions, and compliance certifications (ROHS3, REACH Unaffected, EAR99).

The 416F40011CDR is the preferred selection for new designs and ongoing procurement due to its active product status. The 416F40011CDT remains available through existing inventory channels but is discontinued at the primary distributor level.

Both parts meet identical environmental and regulatory requirements, with MSL 1 rating indicating unlimited shelf life under standard storage conditions. Selection between these parts should be based on packaging requirements: the 416F40011CDR is supplied in Tape & Reel format suitable for automated assembly, while the 416F40011CDT is supplied in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Are the 416F40011CDT and 416F40011CDR electrically identical?

A: Yes. Both parts have identical frequency (40 MHz), frequency stability (±10ppm), load capacitance (18pF), ESR (60 Ohms), operating mode (Fundamental), and temperature range (-20°C to 70°C). They are direct electrical equivalents.

Q: What is the difference between these two parts?

A: The primary differences are product status and packaging format. The 416F40011CDT is discontinued at DiGi Electronics and supplied in bulk packaging. The 416F40011CDR is active and supplied in Tape & Reel (TR) format for automated assembly processes.

Q: Can I use 416F40011CDR as a direct replacement for 416F40011CDT in existing designs?

A: Yes. The parts are mechanically and electrically identical. PCB layout, circuit design, and component placement require no modification. Packaging format differences do not affect circuit performance.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. Both have MSL 1 rating with unlimited shelf life.

Q: Which part should I specify for new designs?

A: Specify the 416F40011CDR for new designs. It maintains active product status and is available in standard Tape & Reel packaging for production assembly.

Q: What are the physical dimensions, and do they affect PCB layout?

A: Both parts measure 0.063" L x 0.047" W (1.60mm x 1.20mm) with a maximum seated height of 0.018" (0.45mm). These dimensions are identical and require no PCB layout changes when substituting between parts.
