7X-25.000MBA-T Equivalent & Substitute Parts

Part Overview

The 7X-25.000MBA-T is a 25 MHz crystal oscillator manufactured by TXC CORPORATION. This CMOS oscillator operates at 3.3V with enable/disable functionality in a 4-SMD, no-lead surface mount package. The device is actively produced and RoHS compliant, serving applications requiring precise 25 MHz frequency generation with low-power operation.

Substitute parts are identified for applications requiring equivalent frequency, output type, voltage supply, and mechanical compatibility. Alternative sources provide identical electrical performance within specified tolerances while maintaining the same package footprint and pinout configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7X-25.000MBA-T are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Frequency: 25 MHz (exact match required)
• Output: CMOS (identical logic family)
• Supply Voltage: 3.3V (identical operating voltage)
• Function: Enable/Disable (identical control functionality)
• Frequency Stability: ±25ppm (identical tolerance specification)
• Operating Temperature: -10°C ~ 70°C (identical range)

Mechanical Equivalence Criteria:

• Package Type: 4-SMD, No Lead (identical pinout and footprint)
• Package Dimensions: 0.126" L x 0.098" W / 3.20mm x 2.50mm (identical placement)
• Mounting Type: Surface Mount (identical assembly method)

Compliance Equivalence Criteria:

• RoHS Status: RoHS Compliant or ROHS3 Compliant (equivalent environmental standards)
• REACH Status: REACH Unaffected (identical regulatory status)
• Moisture Sensitivity Level: 1 (Unlimited) (identical handling requirements)

Substitute parts meeting all three equivalence categories are direct functional and mechanical replacements without circuit modification or board redesign.

Parameter Comparison

Engineering Selection Recommendations

All three oscillators meet the core electrical and mechanical substitution criteria for 25 MHz CMOS applications at 3.3V with enable/disable control. Selection between the main part and substitutes is based on the following factors:

Product Availability and Inventory: The SXO32C3C171-25.000M (Suntsu) offers the highest inventory level at 17,923 pieces. The FKSSD1025 (Diodes Incorporated) provides 6,873 pieces. The 7X-25.000MBA-T (TXC) maintains 3,376 pieces in stock.

Compliance Status: All three parts are RoHS compliant and REACH unaffected. The FKSSD1025 and SXO32C3C171-25.000M carry ROHS3 certification, representing the latest RoHS revision. The 7X-25.000MBA-T carries standard RoHS compliance.

Current Consumption: The 7X-25.000MBA-T specifies a maximum supply current of 20mA. The FKSSD1025 and SXO32C3C171-25.000M both specify 10mA maximum supply current, representing lower power operation. The FKSSD1025 additionally specifies 10µA maximum disable current.

Package Configuration: The 7X-25.000MBA-T and FKSSD1025 are supplied in Tape & Reel packaging. The SXO32C3C171-25.000M is supplied in Bulk packaging. All three maintain identical footprint dimensions and height specifications within 0.004" (0.10mm) variation.

Active Product Status: All three parts maintain active product status with ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the FKSSD1025 or SXO32C3C171-25.000M be used as direct replacements for the 7X-25.000MBA-T without circuit modification?

A: Yes. Both substitute parts maintain identical frequency (25 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, frequency stability (±25ppm), operating temperature range (-10°C ~ 70°C), and package footprint (4-SMD, no lead, 3.20mm x 2.50mm). No circuit modification or board redesign is required.

Q: What is the maximum height difference between the main part and substitute parts?

A: The 7X-25.000MBA-T has a maximum seated height of 0.043" (1.10mm). The FKSSD1025 is 0.045" (1.15mm), and the SXO32C3C171-25.000M is 0.047" (1.20mm). The maximum variation is 0.004" (0.10mm), which remains within standard PCB assembly tolerances for surface mount components.

Q: Are there differences in power consumption between the main part and substitutes?

A: The 7X-25.000MBA-T specifies 20mA maximum supply current. The FKSSD1025 and SXO32C3C171-25.000M both specify 10mA maximum supply current. Applications with strict power budgets benefit from the lower current consumption of the substitute parts. The FKSSD1025 additionally specifies 10µA maximum disable current for low-power standby operation.

Q: What packaging formats are available for each part?

A: The 7X-25.000MBA-T and FKSSD1025 are supplied in Tape & Reel (TR) format, suitable for automated assembly. The SXO32C3C171-25.000M is supplied in Bulk format. Packaging selection depends on production volume and assembly equipment compatibility.

Q: Are all three parts RoHS compliant?

A: Yes. The 7X-25.000MBA-T is RoHS compliant. The FKSSD1025 and SXO32C3C171-25.000M are ROHS3 compliant, representing compliance with the latest RoHS revision. All three parts are REACH unaffected.

Q: What is the moisture sensitivity level for each part?

A: The 7X-25.000MBA-T and FKSSD1025 both specify Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. The SXO32C3C171-25.000M does not specify a moisture sensitivity level in the provided data.
