NJU6366CF1-TE1 Equivalent & Substitute Parts

Part Overview

The NJU6366CF1-TE1 is a 50 MHz CMOS crystal oscillator manufactured by Nisshinbo Micro Devices Inc., designed for applications requiring stable frequency generation with low power consumption and wide supply voltage range. This component operates from 2V to 5.5V and features a standby (power down) function with typical supply current of 10mA and disable current of 1µA.

The NJU6366CF1-TE1 is classified as an obsolete product. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability for production, and support long-term system maintenance where original inventory is depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NJU6366CF1-TE1 is determined by the following critical parameters that must align across candidate parts:

Mandatory Matching Parameters:

• Frequency: 50 MHz
• Output Type: CMOS
• Base Resonator: Crystal
• Operating Temperature Range: -40°C ~ 85°C
• Supply Voltage Compatibility: Overlapping or equivalent range
• Mounting Type: Surface Mount
• Manufacturer: Nisshinbo Micro Devices Inc.

Functional Parameters:

• Standby/Power Down capability
• Supply current characteristics within acceptable operational limits
• Disable current performance

The NJU6368AF1-TE1 qualifies as a substitute part because it maintains the same frequency (50 MHz), CMOS output, crystal-based oscillator architecture, operating temperature range (-40°C ~ 85°C), surface mount configuration, and manufacturer origin. Both parts share the same ECCN and HTSUS classifications, confirming regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The NJU6366CF1-TE1 is obsolete, while the NJU6368AF1-TE1 maintains active product status with Nisshinbo Micro Devices Inc. This status difference directly supports the substitution path for new designs and ongoing production requirements.

Compliance Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, confirming regulatory and trade compliance equivalence. Both parts maintain RoHS non-compliant status, indicating consistent environmental compliance posture.

Supply Voltage Range: The NJU6368AF1-TE1 operates within 2.7V ~ 5.5V, which overlaps the NJU6366CF1-TE1 range of 2V ~ 5.5V. Applications operating above 2.7V experience full compatibility. Applications requiring operation below 2.7V require circuit-level evaluation.

Moisture Sensitivity: The NJU6368AF1-TE1 offers improved moisture handling (MSL 1, Unlimited) compared to the NJU6366CF1-TE1 (MSL 2, 1 Year), providing extended shelf life and reduced storage constraints.

Current Characteristics: The NJU6368AF1-TE1 demonstrates significantly lower supply current (27 µA) compared to the NJU6366CF1-TE1 (10mA), resulting in reduced power consumption for equivalent frequency generation.

Frequently Asked Questions (FAQ)

Q: Can the NJU6368AF1-TE1 directly replace the NJU6366CF1-TE1 in existing designs?

A: Direct replacement is possible for applications operating at supply voltages of 2.7V and above. The NJU6368AF1-TE1 maintains identical frequency (50 MHz), CMOS output, operating temperature range (-40°C ~ 85°C), and surface mount configuration. Package differences (SOT-23-6 for the substitute versus unspecified for the original) require PCB layout verification. Applications requiring operation below 2.7V require alternative solutions.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Product status—NJU6368AF1-TE1 is active while NJU6366CF1-TE1 is obsolete; (2) Supply current—NJU6368AF1-TE1 operates at 27 µA versus 10mA for the original; (3) Minimum supply voltage—NJU6368AF1-TE1 requires 2.7V minimum versus 2V for the original; (4) Package—NJU6368AF1-TE1 uses SOT-23-6 (MTP6); (5) Moisture sensitivity—NJU6368AF1-TE1 offers MSL 1 (Unlimited) versus MSL 2 (1 Year).

Q: Are there any compatibility concerns with the package change?

A: The NJU6368AF1-TE1 uses SOT-23-6 (MTP6) packaging, while the original part's package is not specified. PCB footprint, pin assignment, and mechanical clearance must be verified against the original design. Pin-to-pin compatibility cannot be confirmed without the original part's package specification.

Q: Does the lower supply current of the NJU6368AF1-TE1 affect performance?

A: The NJU6368AF1-TE1 operates at 27 µA supply current, significantly lower than the NJU6366CF1-TE1's 10mA. This represents improved power efficiency and does not indicate performance degradation. Both parts maintain identical frequency stability and CMOS output characteristics for the specified operating conditions.

Q: What is the minimum supply voltage requirement for the substitute part?

A: The NJU6368AF1-TE1 requires a minimum supply voltage of 2.7V. The original NJU6366CF1-TE1 operates from 2V minimum. Applications requiring operation between 2V and 2.7V cannot use the NJU6368AF1-TE1 as a substitute without circuit modification.

Q: Are both parts subject to the same regulatory classifications?

A: Yes. Both the NJU6366CF1-TE1 and NJU6368AF1-TE1 share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, confirming equivalent regulatory and trade compliance status.
