MAX2622EUA-T Equivalent & Substitute Parts

Part Overview

The MAX2622EUA-T is a voltage-controlled oscillator (VCO) IC manufactured by Analog Devices Inc./Maxim Integrated, designed for 868 MHz center frequency applications. This component operates across a 0.4 V to 2.4 V tuning voltage range and delivers -3 ±3 dBm output power with -27 dBc typical 2nd harmonic suppression. The MAX2622EUA-T is classified as obsolete, making identification of equivalent substitute parts essential for ongoing production and maintenance applications. The MAX2622 series provides direct alternatives that maintain electrical and mechanical compatibility while offering improved product status and availability.

Substitute Part Grouping Explanation

Substitution of the MAX2622EUA-T is determined by strict equivalence across all electrical performance parameters and mechanical compatibility criteria. The substitute part must maintain identical specifications for center frequency (868 MHz), frequency tuning range (855–881 MHz), tuning voltage window (0.4 V–2.4 V), supply voltage tolerance (2.7 V–5.5 V), output power level (-3 ±3 dBm), harmonic suppression (-27 dBc typical), maximum current draw (11.5 mA), and frequency pushing coefficient (0.28 MHz/V typical). Physical compatibility requires matching package type (8-TSSOP/8-MSOP) and dimensions (3.00 mm × 3.00 mm × 1.10 mm). Environmental and regulatory compliance must include ROHS3 compliance and MSL 1 rating. The MAX2622EUA+T qualifies as a direct substitute based on complete parameter alignment and identical base product number (MAX2622) designation.

Engineering Selection Recommendations

The MAX2622EUA+T is the direct equivalent substitute for the MAX2622EUA-T. Both components share identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. The primary distinction is product status: the MAX2622EUA-T is classified as obsolete, while the MAX2622EUA+T maintains active status with current manufacturing support. The substitute part is available in Tape & Reel packaging format, whereas the original part is supplied in tube format. This packaging difference does not affect electrical performance or PCB-level compatibility. Selection of the MAX2622EUA+T is appropriate for new designs, production continuity, and replacement applications requiring 868 MHz VCO functionality with guaranteed long-term component availability.

Frequently Asked Questions (FAQ)

Q: Are the MAX2622EUA-T and MAX2622EUA+T electrically identical? A: Yes. Both parts deliver identical electrical performance across all specified parameters, including center frequency (868 MHz), tuning voltage range (0.4 V–2.4 V), output power (-3 ±3 dBm), and harmonic suppression (-27 dBc typical).

Q: What is the difference between these two part numbers? A: The primary difference is product status and packaging format. The MAX2622EUA-T is obsolete and supplied in tube packaging. The MAX2622EUA+T is active and supplied in Tape & Reel format. Electrical specifications and physical dimensions are identical.

Q: Can the MAX2622EUA+T be used as a direct replacement on existing PCBs designed for the MAX2622EUA-T? A: Yes. The MAX2622EUA+T is pin-compatible and dimensionally identical (3.00 mm × 3.00 mm × 1.10 mm, 8-MSOP package). No PCB modifications are required.

Q: Are there any compliance or certification differences? A: No. Both parts maintain ROHS3 compliance, MSL 1 rating, and identical regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001).

Q: Why should I select the MAX2622EUA+T over the MAX2622EUA-T? A: The MAX2622EUA+T is recommended because it maintains active product status with guaranteed manufacturing support and availability. The MAX2622EUA-T is obsolete and subject to supply discontinuation.

Q: Does packaging format (Tube vs. Tape & Reel) affect component performance? A: No. Packaging format affects only handling, storage, and assembly processes. Electrical performance and reliability are unaffected by packaging type.
