7M25000080 25 MHz Crystal Equivalent & Substitute Parts

Part Overview

The 7M25000080 is a 25 MHz surface mount crystal manufactured by TXC CORPORATION. This active product operates across the industrial temperature range of -30°C to 85°C with ±10ppm frequency stability and 18pF load capacitance. The component is packaged in a 4-SMD, No Lead configuration measuring 3.20mm × 2.50mm with a maximum seated height of 0.80mm. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same frequency, load capacitance, frequency stability, temperature range, and package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7M25000080 is determined by strict equivalence across the following critical parameters:

• Frequency: Must be 25 MHz
• Frequency Stability: Must be ±10ppm
• Load Capacitance: Must be 18pF
• Operating Temperature Range: Must span -30°C to 85°C
• Package / Case: Must be 4-SMD, No Lead
• Mounting Type: Must be Surface Mount

The identified substitute parts ECS-250-18-33B-CKY-TR and ECS-250-18-36B-CKY-TR satisfy these core electrical and mechanical requirements. Both parts maintain identical frequency, frequency stability, load capacitance, and temperature specifications. Both are surface mount components in 4-SMD, No Lead packages. Variations in ESR (Equivalent Series Resistance) and physical dimensions are secondary parameters that do not prevent substitution when primary specifications align.

Parameter Comparison

Engineering Selection Recommendations

Both ECS Inc. substitute parts maintain full compliance with the electrical and regulatory requirements of the 7M25000080. The ECS-250-18-33B-CKY-TR and ECS-250-18-36B-CKY-TR are active products with ROHS3 compliance, exceeding the RoHS Compliant status of the original part. All three components share identical REACH Unaffected and EAR99 ECCN classifications, ensuring consistent regulatory treatment across supply chain applications.

The primary distinction between the two ECS substitutes is ESR specification: the ECS-250-18-33B-CKY-TR operates at 40 Ohms, while the ECS-250-18-36B-CKY-TR operates at 50 Ohms. The original 7M25000080 does not specify ESR in the provided parameters. Physical dimensions vary slightly between the ECS-250-18-36B-CKY-TR (2.50mm × 2.00mm, 0.65mm height) and the other two parts (3.20mm × 2.50mm, 0.80mm height), though all maintain 4-SMD, No Lead package compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ECS-250-18-33B-CKY-TR and ECS-250-18-36B-CKY-TR be used interchangeably with the 7M25000080?

A: Both ECS parts meet the core electrical specifications: 25 MHz frequency, ±10ppm stability, 18pF load capacitance, and -30°C to 85°C operating range. Both are surface mount 4-SMD, No Lead packages. Substitution is valid when ESR and physical dimension variations do not conflict with circuit design requirements.

Q: What is the significance of the different ESR values (40 Ohms vs. 50 Ohms)?

A: ESR (Equivalent Series Resistance) affects crystal oscillator circuit performance, particularly startup behavior and power consumption. The 7M25000080 does not specify ESR in the provided data. Circuit designers must confirm that the selected substitute's ESR is compatible with the oscillator circuit design.

Q: Are there physical dimension differences between the substitute parts?

A: Yes. The ECS-250-18-33B-CKY-TR matches the 7M25000080 footprint (3.20mm × 2.50mm, 0.80mm height). The ECS-250-18-36B-CKY-TR is smaller (2.50mm × 2.00mm, 0.65mm height). Both are 4-SMD, No Lead packages. PCB layout compatibility must be verified for the smaller variant.

Q: Do all three parts have the same regulatory compliance?

A: The 7M25000080 is RoHS Compliant. Both ECS substitutes are ROHS3 Compliant, which represents enhanced compliance. All three share identical REACH Unaffected status and EAR99 ECCN classification.

Q: What packaging formats are available for these parts?

A: The 7M25000080 is specified with "-" packaging notation. The ECS-250-18-33B-CKY-TR and ECS-250-18-36B-CKY-TR are supplied in Tape & Reel (TR) format. Packaging format compatibility with procurement and assembly processes must be confirmed.
