EVA-7M-0 Equivalent & Substitute Parts

Part Overview

The EVA-7M-0 is a Navigation GLONASS, GPS, GNSS Transceiver Module manufactured by u-blox, operating at 1.575GHz with surface mount packaging in a 43-SMD Module configuration. This part is classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The module integrates multi-constellation GNSS reception with multiple serial interfaces (I2C, SPI, UART, USB) and operates across a wide supply voltage range of 1.65V to 3.6V.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EVA-7M-0 is determined by the following critical parameters:

• RF Standard Compatibility: All substitute parts must support GLONASS and GPS protocols at 1.575GHz
• Voltage Supply Range: Substitute parts must operate within or encompass the 1.65V ~ 3.6V supply range
• Serial Interface Support: Substitute parts must provide I2C, SPI, UART, and USB interfaces
• Mounting Type: All substitutes must be surface mount modules
• RoHS Compliance: Substitute parts must maintain RoHS compliance status
• MSL Rating: Substitute parts must meet or exceed MSL 3 rating

The three identified substitute parts (EVA-8M-0, EVA-M8M-0, EVA-M8Q-0) meet these core substitution criteria while offering enhanced receiver sensitivity and expanded GNSS constellation support (BeiDou and Galileo in addition to GLONASS and GPS).

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (EVA-8M-0, EVA-M8M-0, EVA-M8Q-0) are Active products from u-blox with ROHS3 compliance, providing long-term availability and regulatory alignment compared to the Obsolete EVA-7M-0.

EVA-8M-0 offers the closest current consumption profile (16mA receiving) to the original part while maintaining dual-constellation GLONASS/GPS support. This part is suitable for applications where power efficiency and minimal constellation expansion are acceptable.

EVA-M8M-0 and EVA-M8Q-0 provide expanded GNSS constellation support (BeiDou, Galileo, GLONASS, GPS) with improved receiver sensitivity (-167dBm versus -160dBm). Both parts operate at 22mA receiving current and support identical serial interfaces. The primary distinction is packaging format: EVA-M8M-0 is supplied in Cut Tape & Digi-Reel format, while EVA-M8Q-0 is supplied in Tape & Reel format.

All substitute parts maintain the required 1.65V ~ 3.6V supply voltage range, I2C/SPI/UART/USB interface compatibility, and MSL 3 moisture sensitivity rating. Operating temperature ranges extend to -40°C on the substitute parts, providing enhanced low-temperature performance.

Frequently Asked Questions (FAQ)

Q: Can EVA-8M-0, EVA-M8M-0, and EVA-M8Q-0 be used interchangeably with EVA-7M-0?

A: Yes, all three parts meet the core substitution criteria: identical RF frequency (1.575GHz), compatible serial interfaces (I2C, SPI, UART, USB), matching supply voltage range (1.65V ~ 3.6V), surface mount configuration, and equivalent MSL ratings. Package form factors differ (43-TFLGA versus 42-TFLGA), requiring PCB layout verification.

Q: What are the key differences between the substitute parts?

A: EVA-8M-0 supports GLONASS and GPS only, while EVA-M8M-0 and EVA-M8Q-0 add BeiDou and Galileo constellation support. Receiver sensitivity improves progressively: EVA-8M-0 at -164dBm, EVA-M8M-0 and EVA-M8Q-0 at -167dBm. Current consumption increases from 16mA (EVA-8M-0) to 22mA (EVA-M8M-0 and EVA-M8Q-0). Packaging differs: EVA-M8M-0 uses Cut Tape & Digi-Reel, EVA-M8Q-0 uses Tape & Reel.

Q: Are there package compatibility concerns?

A: Yes. The EVA-7M-0 uses a 43-SMD Module package, while EVA-8M-0 uses 43-TFLGA Module and EVA-M8M-0/EVA-M8Q-0 use 42-TFLGA packages. PCB footprint and land pattern verification is required before substitution.

Q: Do all substitute parts support the same data rate?

A: The EVA-7M-0 specifies 9.6kBaud data rate. Substitute parts do not list maximum data rate specifications in the provided parameters. Consult detailed datasheets for data rate compatibility confirmation.

Q: What is the inventory status of substitute parts?

A: EVA-M8M-0 has the highest inventory (132,450 pcs), followed by EVA-8M-0 (2,455 pcs) and EVA-M8Q-0 (2,180 pcs), providing supply chain flexibility for production requirements.
