CTS-Frequency Controls 416F38013IAT 38 MHz Crystal Equivalent & Substitute Parts

Part Overview

The CTS-Frequency Controls 416F38013IAT is a 38 MHz fundamental mode crystal oscillator in a 4-SMD, No Lead surface mount package. This part is discontinued at DiGi Electronics but remains available through inventory channels with 973 pieces in stock. The 38 MHz frequency with ±10ppm tolerance and 10pF load capacitance serves applications requiring precise timing references in communication and industrial equipment. Due to discontinuation status, equivalent and substitute parts from the same manufacturer series provide direct alternatives for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 416F38013IAT is determined by the following critical parameters that must remain constant or compatible:

Fixed Parameters (Must Match):

• Frequency: 38 MHz
• Frequency Tolerance: ±10ppm
• Operating Mode: Fundamental
• Operating Temperature Range: -40°C to 85°C
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 0.063" L x 0.047" W (1.60mm x 1.20mm)
• Height - Seated (Max): 0.018" (0.45mm)
• ESR: 60 Ohms
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

Variable Parameters (Allowed Variation):

• Load Capacitance: 8pF, 10pF, or 12pF (circuit-dependent selection)
• Frequency Stability: ±20ppm or ±30ppm (tighter stability available)
• Product Status: Active or Discontinued (availability consideration)
• Packaging: Bulk or Tape & Reel (TR)

The 416F38013IAT can be substituted with parts from the CTS-Frequency Controls 416 series that maintain identical frequency, tolerance, operating mode, temperature range, and physical package specifications while allowing load capacitance and frequency stability variations based on circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Load Capacitance):

416F38013IAR is the primary direct replacement for 416F38013IAT. Both parts specify 10pF load capacitance and ±30ppm frequency stability. The 416F38013IAR maintains active product status with 1036 pieces in inventory, providing supply continuity for the discontinued 416F38013IAT.

416F38012IAR offers equivalent functionality with 10pF load capacitance but features improved frequency stability at ±20ppm compared to the ±30ppm of the original part. This part is active with 694 pieces available.

Load Capacitance Variants:

416F38013IKR provides 8pF load capacitance with ±30ppm frequency stability. Selection of this variant requires circuit design confirmation that 8pF load capacitance is compatible with the oscillator circuit.

416F38013ILR provides 12pF load capacitance with ±30ppm frequency stability. Selection of this variant requires circuit design confirmation that 12pF load capacitance is compatible with the oscillator circuit.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can I use 416F38013IKR (8pF) or 416F38013ILR (12pF) as direct replacements for 416F38013IAT (10pF)?

A: Load capacitance selection depends on the oscillator circuit design. The load capacitance value must match the circuit's load capacitance specification. If your circuit specifies 10pF load capacitance, use 416F38013IAR or 416F38012IAR. If your circuit specifies 8pF or 12pF, the corresponding variants are appropriate. Mismatched load capacitance will result in frequency deviation outside tolerance specifications.

Q: What is the difference between 416F38013IAT and 416F38012IAR?

A: Both parts specify 38 MHz frequency, ±10ppm tolerance, 10pF load capacitance, and identical physical packaging. The primary difference is frequency stability: 416F38013IAT specifies ±30ppm while 416F38012IAR specifies ±20ppm. The 416F38012IAR provides tighter frequency stability performance. Additionally, 416F38012IAR is active with current availability, while 416F38013IAT is discontinued.

Q: Are all substitute parts available in the same packaging format?

A: The main part 416F38013IAT is supplied in bulk packaging. All substitute parts (416F38013IKR, 416F38013ILR, 416F38012IAR, 416F38013IAR) are supplied in Tape & Reel (TR) packaging. Both packaging formats are compatible with automated assembly processes. Confirm packaging requirements with your procurement or assembly department.

Q: Do all parts meet the same regulatory and compliance standards?

A: All parts in this comparison are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH Unaffected. All parts share identical ECCN (EAR99) and HTSUS (8541.60.0060) classifications, ensuring regulatory equivalence for export and compliance documentation.

Q: Which substitute part should I select for new designs?

A: For new designs requiring 10pF load capacitance, select 416F38013IAR or 416F38012IAR. Both are active products with strong inventory availability. If improved frequency stability is required, 416F38012IAR with ±20ppm specification is the preferred choice. For alternative load capacitance requirements, select the corresponding variant (8pF or 12pF) after confirming circuit compatibility.
