LC72722PM-TLM-E RF Demodulator IC Equivalent & Substitute Parts

Part Overview

The LC72722PM-TLM-E is an RF demodulator integrated circuit manufactured by onsemi, housed in a 24-SOIC package with a 31dB gain specification. The device operates at 4.5V to 5.5V supply voltage with 9mA current consumption and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute components is essential for design continuity, production support, and system maintenance where this demodulator is currently deployed.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LC72722PM-TLM-E are identified based on the following criteria:

• Function: RF demodulator integrated circuit
• Mounting Type: Surface mount technology
• Supply Voltage Compatibility: Operating voltage range overlap or compatibility with 4.5V ~ 5.5V specification
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status
• Product Status: Active status preferred for long-term availability and support
• Gain Performance: Comparable demodulation gain characteristics

The substitute parts listed (AD8333ACPZ-REEL7 and LT5516EUF#TRPBF) are both active RF demodulator ICs from Analog Devices Inc. with ROHS3 compliance. However, they operate in different frequency bands and have different package configurations, requiring careful application assessment.

Parameter Comparison

Engineering Selection Recommendations

AD8333ACPZ-REEL7 is an active RF demodulator IC suitable for applications requiring 0Hz to 50MHz RF frequency operation. This part maintains ROHS3 compliance and REACH unaffected status. The 32-WFQFN package differs from the original 24-SOIC, requiring PCB layout redesign. Supply voltage range (4.5V ~ 6V) overlaps with the original specification. Current consumption increases to 51mA compared to 9mA in the original part.

LT5516EUF#TRPBF is an active RF demodulator IC designed for 800MHz to 1.5GHz RF frequency operation. This part maintains ROHS3 compliance and REACH unaffected status with superior moisture sensitivity (MSL 1). The 16-WQFN package requires PCB redesign. Supply voltage range (4V ~ 5.25V) is compatible with the original specification. Current consumption increases significantly to 150mA.

Selection between these substitutes depends on the target RF frequency band of the application. The original LC72722PM-TLM-E frequency specifications are not provided in the available data, making frequency band compatibility assessment necessary before final selection.

Frequently Asked Questions (FAQ)

Q: Why is the LC72722PM-TLM-E classified as obsolete? A: The LC72722PM-TLM-E is listed with obsolete product status, indicating onsemi has discontinued manufacturing and support for this component. Substitute parts ensure design continuity and production availability.

Q: Can AD8333ACPZ-REEL7 directly replace LC72722PM-TLM-E without PCB modifications? A: No. The AD8333ACPZ-REEL7 uses a 32-WFQFN package compared to the 24-SOIC package of the original part, requiring PCB layout redesign and pin-to-pin verification.

Q: Can LT5516EUF#TRPBF directly replace LC72722PM-TLM-E without PCB modifications? A: No. The LT5516EUF#TRPBF uses a 16-WQFN package compared to the 24-SOIC package of the original part, requiring PCB layout redesign and pin-to-pin verification.

Q: What is the primary difference between the two substitute parts? A: The AD8333ACPZ-REEL7 operates at 0Hz to 50MHz RF frequency, while the LT5516EUF#TRPBF operates at 800MHz to 1.5GHz RF frequency. Selection depends on the target application frequency band.

Q: Are both substitute parts RoHS3 compliant? A: Yes. Both AD8333ACPZ-REEL7 and LT5516EUF#TRPBF are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: How do the current consumption specifications compare? A: The original LC72722PM-TLM-E draws 9mA. The AD8333ACPZ-REEL7 draws 51mA, and the LT5516EUF#TRPBF draws 150mA. Power budget and thermal management must be reassessed for substitute parts.

Q: What is the moisture sensitivity difference between these parts? A: The LC72722PM-TLM-E has MSL 4 (72 Hours), AD8333ACPZ-REEL7 has MSL 3 (168 Hours), and LT5516EUF#TRPBF has MSL 1 (Unlimited). Lower MSL values indicate better moisture tolerance and longer shelf life.
