Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

Select 416F37413ILR as the primary substitute. This part maintains all electrical parameters of the 416F37413ILT, including 37.4 MHz frequency, ±10ppm tolerance, 12pF load capacitance, and 60 Ohms ESR. The part is currently Active in production status with 1104 units in stock, ensuring supply continuity. Both parts are ROHS3 compliant and carry identical environmental certifications (REACH Unaffected, EAR99 classification). The only difference is packaging format (Tape & Reel vs. bulk), which does not affect electrical or mechanical performance.

Alternative Direct Replacement:

416F37412ILR provides identical electrical and mechanical specifications with the exception of improved frequency stability (±20ppm vs. ±30ppm). This enhanced stability characteristic does not preclude substitution and may provide performance benefits in applications sensitive to frequency drift. This part is Active with 796 units in stock.

For Load Capacitance Flexibility:

416F37413IAR is suitable for circuits designed to operate with 10pF load capacitance. All other electrical parameters match the original specification. This part is Active with 785 units in stock. Selection of this variant requires confirmation that the circuit design accommodates the 10pF load capacitance specification.

All substitute parts carry ROHS3 compliance and MSL 1 rating, meeting the environmental and handling requirements of the original component.

Frequently Asked Questions (FAQ)

Q: Can 416F37413ILR be used as a direct replacement for 416F37413ILT?

A: Yes. The 416F37413ILR is a direct parametric equivalent. Both parts share identical frequency (37.4 MHz), tolerance (±10ppm), load capacitance (12pF), ESR (60 Ohms), operating temperature range (-40°C ~ 85°C), and physical package dimensions (4-SMD, No Lead, 1.60mm x 1.20mm x 0.45mm max height). The difference in packaging format (Tape & Reel vs. bulk) does not affect electrical or mechanical performance.

Q: What is the difference between 416F37413ILR and 416F37412ILR?

A: Both parts are parametric equivalents with identical frequency, tolerance, load capacitance, ESR, package, and temperature range. The 416F37412ILR offers improved frequency stability at ±20ppm compared to ±30ppm for the 416F37413ILR. This difference does not prevent substitution; the tighter stability specification of 416F37412ILR may provide performance advantages in applications requiring enhanced frequency accuracy.

Q: Can 416F37413IAR replace 416F37413ILT?

A: 416F37413IAR is compatible with the original part for applications where the circuit design accommodates 10pF load capacitance. All other electrical parameters (frequency, tolerance, ESR, operating temperature) and mechanical specifications (package, dimensions) are identical. Substitution requires verification that the circuit is designed for 10pF load capacitance operation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (416F37412ILR, 416F37413ILR, and 416F37413IAR) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance of the original 416F37413ILT.

Q: What is the significance of the product status difference (Discontinued vs. Active)?

A: The 416F37413ILT is discontinued at DiGi Electronics, indicating no further procurement availability through this distributor. All substitute parts are Active in production status, ensuring ongoing availability and supply chain continuity for new designs and production runs.
