Substitute Part Grouping Explanation

Substitute parts for the 416F36035ATT are qualified based on the following critical parameters:

Frequency: 36 MHz (exact match required)
Frequency Tolerance: ±30ppm (exact match required)
Load Capacitance: 6pF (exact match required)
ESR: 80 Ohms (exact match required)
Operating Mode: Fundamental (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)
Operating Temperature Range: -10°C to 60°C (exact match required)
RoHS3 Compliance (exact match required)
MSL Rating: 1 (exact match required)

The substitute parts listed below meet all these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Engineering Selection Recommendations

Both substitute parts 416F36033ATR and 416F36035ATR are active products with current availability. The 416F36035ATT is discontinued at DiGi Electronics, making substitution necessary for new procurement.

Selection between the two active substitutes should be based on packaging requirements:

416F36033ATR: Tape & Reel packaging, 1107 units in stock, frequency stability ±30ppm
416F36035ATR: Tape & Reel packaging, 928 units in stock, frequency stability ±50ppm

Both parts maintain ROHS3 compliance and REACH unaffected status. All three parts share identical electrical performance parameters and physical dimensions, ensuring direct functional replacement in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can 416F36033ATR and 416F36035ATR be used interchangeably with 416F36035ATT?

A: Yes. All three parts meet identical specifications for frequency (36 MHz), frequency tolerance (±30ppm), load capacitance (6pF), ESR (80 Ohms), package type (4-SMD, No Lead), physical dimensions, operating temperature range, and compliance certifications.

Q: What is the difference between the substitute parts?

A: The primary differences are product status and packaging. The 416F36035ATT is discontinued; both substitutes are active. The 416F36033ATR specifies ±30ppm frequency stability, while 416F36035ATR specifies ±50ppm. Both substitutes are supplied in Tape & Reel packaging, whereas the original part was supplied in bulk.

Q: Are there packaging considerations for these substitutes?

A: The original part (416F36035ATT) was supplied in bulk packaging. Both substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. Tape & Reel packaging is compatible with standard pick-and-place equipment.

Q: Do these parts require different PCB footprints?

A: No. All three parts use the 4-SMD, No Lead package with identical dimensions (0.063" L x 0.047" W, 0.018" max height). PCB footprints are directly compatible.

Q: Are compliance certifications maintained across all three parts?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.60.0060) classifications.
