LMK61E2BAA-SIAR Clock Oscillator IC Equivalent & Substitute Parts

Part Overview

The LMK61E2BAA-SIAR is an active clock oscillator IC manufactured by Texas Instruments, designed for high-frequency timing applications. This 8-QFM (7x5) surface mount device operates across 400MHz, 900MHz, and 1GHz frequency bands with a supply voltage range of 3.135V to 3.465V. The part is currently in active production status and carries ROHS3 compliance certification. Substitute parts are identified when packaging format changes or inventory availability requires alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the LMK61E2BAA-SIAR are determined by equivalence across the following critical parameters:

Frequency Range: 400MHz, 900MHz, 1GHz
Voltage - Supply: 3.135V ~ 3.465V
Current - Supply: 162 mA
Operating Temperature: -40°C ~ 85°C (TA)
Package / Case: 8-SMD Module
Supplier Device Package: 8-QFM (7x5)
Mounting Type: Surface Mount

Engineering Selection Recommendations

All three parts—LMK61E2BAA-SIAR, LMK61E2BAA-SIAT, and LMK61E2BBA-SIAT—are active production devices from Texas Instruments with identical electrical specifications and mechanical form factors. Selection between these parts is determined by packaging and supply chain requirements rather than functional differences.

LMK61E2BAA-SIAR in Tape & Reel format is suitable for high-volume automated assembly operations. LMK61E2BAA-SIAT and LMK61E2BBA-SIAT in Cut Tape & Digi-Reel® format accommodate lower-volume production runs or manual assembly workflows. All parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can LMK61E2BAA-SIAT replace LMK61E2BAA-SIAR in a circuit design?

A: Yes. Both parts share identical electrical parameters (frequency range, supply voltage, current consumption, operating temperature) and mechanical specifications (8-QFM package, surface mount). The difference is packaging format: Tape & Reel versus Cut Tape & Digi-Reel®. Circuit performance is equivalent.

Q: What is the difference between LMK61E2BAA-SIAT and LMK61E2BBA-SIAT?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference lies in the part number designation (BAA versus BBA), which reflects manufacturing or product line differentiation by Texas Instruments. All other parameters, including frequency, voltage, current, temperature range, and package type, are identical.

Q: Does packaging format affect PCB assembly compatibility?

A: No. Tape & Reel and Cut Tape & Digi-Reel® are supply formats for component handling and feeding into assembly equipment. The physical component dimensions, pin configuration, and electrical interface remain unchanged. PCB footprint and assembly process compatibility are identical across all three parts.

Q: Are all three parts suitable for -40°C to 85°C operating environments?

A: Yes. All three parts—LMK61E2BAA-SIAR, LMK61E2BAA-SIAT, and LMK61E2BBA-SIAT—are rated for -40°C to 85°C operating temperature range. Moisture sensitivity level (MSL 3, 168 hours) applies uniformly across all variants.

Q: Which part should be selected for high-volume production?

A: LMK61E2BAA-SIAR in Tape & Reel format is optimized for high-volume automated assembly. LMK61E2BAA-SIAT and LMK61E2BBA-SIAT in Cut Tape & Digi-Reel® format are suitable for lower-volume or mixed-assembly environments. Selection depends on production volume and assembly equipment capability, not electrical performance.
