7M24077005 24 MHz Crystal Equivalent & Substitute Parts

Part Overview

The 7M24077005 is a 24 MHz surface mount crystal manufactured by TXC CORPORATION. This component is classified as an active product and is designed for applications requiring precise frequency generation at 24 MHz with tight frequency tolerance specifications. The crystal operates across the industrial temperature range of -20°C to 70°C and is packaged in a compact 4-SMD, No Lead configuration measuring 3.20mm x 2.50mm.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits the use of alternative manufacturers' components that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7M24077005 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 24.0000 MHz (exact match required)
• Frequency Tolerance: ±30 ppm (exact match required)
• Load Capacitance: 18 pF (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 3.20mm x 2.50mm (exact match required)
• Height - Seated (Max): 0.80 mm (exact match required)
• Operating Temperature Range: -20°C to 70°C (exact match required)
• Mounting Type: Surface Mount (exact match required)

Acceptable Variation Parameters:

• Frequency Stability: ±50 ppm (specification met by substitute)
• ESR (Equivalent Series Resistance): May vary if not specified in main part
• Packaging Format: Tape & Reel acceptable for substitute
• RoHS Compliance Status: Both RoHS3 and RoHS Compliant acceptable

The substitute part 403C35D24M00000 from CTS-Frequency Controls meets all mandatory matching criteria and is therefore classified as a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 403C35D24M00000 manufactured by CTS-Frequency Controls is a direct equivalent to the 7M24077005. Selection between these two components is based on the following engineering criteria:

Product Status: Both components are classified as active products, indicating ongoing manufacturer support and availability.

Regulatory Compliance: Both components satisfy RoHS requirements. The 403C35D24M00000 carries ROHS3 compliance, which represents a more recent regulatory standard. Both components are REACH Unaffected and carry identical ECCN and HTSUS classifications, confirming equivalence for export and tariff purposes.

Electrical Specifications: All critical electrical parameters are identical, including frequency, tolerance, stability, and load capacitance. The CTS-Frequency Controls part provides additional specification detail with an ESR value of 60 Ohms and Fundamental operating mode designation.

Mechanical Compatibility: Physical dimensions, package configuration, and mounting type are identical. Both components fit the same PCB footprint and reflow profile requirements.

Supply Availability: The 403C35D24M00000 demonstrates significantly higher inventory availability (19,545 pieces) compared to the 7M24077005 (821 pieces), making it a viable alternative for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 403C35D24M00000 be used as a direct replacement for the 7M24077005 in existing designs?

A: Yes. The 403C35D24M00000 meets all mandatory electrical and mechanical specifications. No circuit modifications are required. Both components share identical frequency, tolerance, load capacitance, package configuration, and operating temperature range.

Q: Are there any differences in PCB layout or footprint requirements?

A: No. Both components use the 4-SMD, No Lead package with identical physical dimensions (3.20mm x 2.50mm) and maximum seated height (0.80mm). PCB footprints are interchangeable.

Q: What is the significance of the ESR specification provided for the CTS part?

A: ESR (Equivalent Series Resistance) of 60 Ohms is a characteristic of the crystal's internal resistance. This specification is provided by CTS-Frequency Controls but not specified for the TXC part. The value does not affect substitution eligibility and is within normal operating parameters for 24 MHz crystals in this package class.

Q: Do both components require identical handling and storage conditions?

A: Both components carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard ESD precautions apply to both components.

Q: Are there regulatory or compliance differences between the two parts?

A: Both components are RoHS Compliant and REACH Unaffected. The 403C35D24M00000 carries ROHS3 compliance, representing alignment with the most current RoHS directive. Both share identical ECCN (EAR99) and HTSUS (8541.60.0060) classifications.

Q: Which component should be selected for new designs?

A: Selection is based on supply chain requirements and inventory availability. The 403C35D24M00000 offers higher inventory availability and ROHS3 compliance. The 7M24077005 remains a valid choice if existing supplier relationships or inventory management practices favor TXC CORPORATION components.
