7X-30.000MBA-T Equivalent & Substitute Parts

Part Overview

The 7X-30.000MBA-T is a 30 MHz XO (Standard) CMOS oscillator manufactured by TXC CORPORATION. This surface mount device operates at 3.3V with Enable/Disable functionality, housed in a 4-SMD, No Lead package. The part is currently Active in product status with 697 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory depletion, or when alternative packaging formats are required for manufacturing flexibility. The 7X-30.000MBB-T represents an equivalent alternative with identical electrical and mechanical specifications, though with different packaging and frequency stability characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7X-30.000MBA-T is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 30 MHz
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Operating Temperature Range: -10°C ~ 70°C
• Maximum Supply Current: 20mA
• Package Type: 4-SMD, No Lead
• Physical Dimensions: 3.20mm x 2.50mm x 1.10mm (Max)
• Mounting Type: Surface Mount

Variable Parameters (Allowed Differences):

• Frequency Stability: ±25ppm to ±50ppm
• Packaging Format: Tape & Reel (TR) vs. Cut Tape (CT) & Digi-Reel®
• Product Status: Active vs. Obsolete
• Inventory Availability

The 7X-30.000MBB-T qualifies as a direct substitute based on identical electrical performance, mechanical compatibility, and package footprint. The primary distinction is the frequency stability specification (±50ppm vs. ±25ppm) and packaging delivery format.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: 7X-30.000MBA-T

The 7X-30.000MBA-T is the recommended choice for new designs and ongoing production. This part maintains Active product status with confirmed inventory availability (697 units in stock). The ±25ppm frequency stability specification provides tighter tolerance performance. RoHS compliance and MSL 1 rating confirm suitability for standard manufacturing and storage conditions without special handling requirements.

Alternative Selection: 7X-30.000MBB-T

The 7X-30.000MBB-T serves as a functional equivalent when the primary part becomes unavailable or when Cut Tape packaging is preferred for specific assembly processes. This part is currently marked Obsolete, indicating limited future availability. The ±50ppm frequency stability is less stringent than the primary part but remains within acceptable tolerance for applications not requiring precision timing. Higher inventory (1808 units) may provide short-term supply security despite obsolete status.

Compliance Considerations:

Both parts carry identical regulatory certifications: RoHS Compliant, REACH Unaffected, and ECCN EAR99 classification. MSL 1 rating eliminates moisture sensitivity concerns for both options. Selection between these parts should prioritize the Active status part (7X-30.000MBA-T) for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 7X-30.000MBB-T directly replace the 7X-30.000MBA-T on existing PCBs?

A: Yes. Both parts share identical package dimensions (3.20mm x 2.50mm x 1.10mm), mounting type (Surface Mount), and pin configuration (4-SMD, No Lead). PCB footprints are interchangeable without modification.

Q: What is the significance of the frequency stability difference (±25ppm vs. ±50ppm)?

A: Frequency stability defines the maximum deviation from the nominal 30 MHz specification across the operating temperature range (-10°C ~ 70°C). The 7X-30.000MBA-T (±25ppm) provides tighter frequency tolerance. Applications requiring precision timing should specify the tighter tolerance part. The ±50ppm specification of the 7X-30.000MBB-T is acceptable for general-purpose timing applications.

Q: What packaging format differences exist between these parts?

A: The 7X-30.000MBA-T is supplied in Tape & Reel (TR) format, standard for high-volume automated assembly. The 7X-30.000MBB-T is supplied in Cut Tape (CT) & Digi-Reel® format, suitable for lower-volume or mixed-component pick-and-place operations. Packaging format does not affect electrical or mechanical performance.

Q: Why is the 7X-30.000MBB-T marked Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. While inventory may remain available, future procurement cannot be guaranteed. New designs should specify the Active part (7X-30.000MBA-T) to ensure long-term supply chain continuity.

Q: Are both parts suitable for RoHS-compliant applications?

A: Yes. Both the 7X-30.000MBA-T and 7X-30.000MBB-T carry RoHS Compliant certification and REACH Unaffected status, confirming compliance with environmental and hazardous substance regulations.

Q: What is MSL 1 rating and how does it affect handling?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without special moisture control measures. Both parts require no desiccant storage, vacuum sealing, or bake-out procedures prior to assembly. Standard warehouse storage conditions are acceptable.
