Substitute Part Grouping Explanation

Substitution of the 4MA148500Z4BACTGI is determined by strict alignment of the following critical parameters:

• Frequency Match: 148.5 MHz (exact)
• Output Configuration: LVDS (required for signal compatibility)
• Oscillator Type: XO (Standard) with Enable/Disable function
• Base Resonator: MEMS technology
• Package: 6-SMD, No Lead with identical physical dimensions (5.00mm x 3.20mm x 0.90mm max height)
• Operating Temperature: -40°C ~ 85°C minimum coverage
• Mounting: Surface Mount

The ASFLMPLV-148.500MHZ-LR-T from Abracon LLC meets all substitution criteria. While the supply voltage range differs (2.25V ~ 3.6V versus 2.5V fixed), the substitute operates within the original part's 2.5V specification, ensuring electrical compatibility. Both parts share identical package geometry, frequency, output type, and functional characteristics.

Engineering Selection Recommendations

The ASFLMPLV-148.500MHZ-LR-T is the qualified substitute for the obsolete 4MA148500Z4BACTGI. Selection is based on:

• Product Status: The original part is Obsolete. The substitute is Active, ensuring long-term availability and supply chain continuity.
• Compliance: The substitute is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.
• Electrical Compatibility: Both parts operate at 148.5 MHz with LVDS output and Enable/Disable functionality. The substitute's wider supply voltage range (2.25V ~ 3.6V) encompasses the original 2.5V specification.
• Physical Compatibility: Identical package dimensions and surface mount configuration enable direct PCB layout compatibility without redesign.
• Functional Equivalence: Both parts are MEMS-based XO oscillators with matching frequency stability and temperature operating range.

Frequently Asked Questions (FAQ)

Q: Can the ASFLMPLV-148.500MHZ-LR-T directly replace the 4MA148500Z4BACTGI on existing PCBs?

A: Yes. Both parts share identical 6-SMD, No Lead package dimensions (5.00mm x 3.20mm x 0.90mm max height) and surface mount configuration. No PCB layout modifications are required.

Q: What is the impact of the different supply voltage specifications?

A: The original part specifies 2.5V fixed supply. The substitute operates across 2.25V ~ 3.6V. Since 2.5V falls within the substitute's operating range, electrical compatibility is maintained. System power supply design remains unchanged.

Q: Are there differences in current consumption between these parts?

A: The original part specifies 100mA typical supply current. The substitute specifies 40mA maximum supply current, representing improved power efficiency. This difference does not affect compatibility but may reduce system power consumption.

Q: Do both parts support Enable/Disable functionality?

A: Yes. Both the 4MA148500Z4BACTGI and ASFLMPLV-148.500MHZ-LR-T include Enable/Disable function, maintaining identical control interface requirements.

Q: What is the frequency stability of the substitute part?

A: The substitute part's frequency stability specification is not provided in the available data. The original part specifies ±50ppm. Confirm frequency stability requirements with the substitute manufacturer if this parameter is critical for your application.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating identical moisture handling and storage requirements.
