Key Parameters

Substitute Part Grouping Explanation

Substitution of the GPS-622F is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Operating temperature range: -40°C to 85°C (must match or exceed)
• Mounting type: Surface Mount (mandatory for PCB integration)
• GNSS protocol support: GPS capability (minimum requirement)
• Sensitivity: -161dB or better (equal or superior reception)
• Supply voltage compatibility: Overlap with 2.7V ~ 5.5V range
• RoHS compliance status: Active compliance required for new designs

Substitute Parts Identified:

GP-01 (RF Solutions): Multi-constellation receiver supporting GPS, GLONASS, GNSS, and BeiDou with -162dBm sensitivity. Surface mount 24-SMD module. Supply voltage 2.7V ~ 3.6V. Operating temperature -40°C to 85°C. ROHS3 compliant. Data interfaces include GPIO, I2C, SPI, UART.

GP-02 (Ai-Thinker): Multi-constellation receiver supporting GPS, GLONASS, and GNSS with -162dBm sensitivity. Surface mount 18-SMD module. Supply voltage 2.7V ~ 3.6V. Operating temperature -40°C to 85°C. ROHS3 compliant. Data interface UART only.

Both substitutes meet the core substitution parameters: operating temperature range, surface mount capability, GPS protocol support, superior sensitivity, and RoHS compliance. The substitutes extend functionality to multi-constellation reception while maintaining electrical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

For GPS-Only Applications: The GPS-622F is obsolete and no longer available for new production. GP-01 and GP-02 both provide GPS reception capability with superior sensitivity (-162dBm vs. -161dB) and active product status. Both substitutes maintain the -40°C to 85°C operating temperature range and surface mount form factor.

Voltage Supply Consideration: The GPS-622F operates at 2.7V ~ 5.5V. Both substitutes operate at 2.7V ~ 3.6V. Designs currently utilizing the upper voltage range (3.6V ~ 5.5V) require power supply redesign to accommodate the substitute parts.

Data Interface Compatibility: The GPS-622F uses PCB surface mount connection. GP-01 provides multiple interface options (GPIO, I2C, SPI, UART), while GP-02 provides UART only. Design integration requirements determine which substitute is appropriate.

Regulatory Compliance: Both GP-01 and GP-02 carry ROHS3 compliance certification, meeting current regulatory requirements for new designs. The GPS-622F carries RoHS Compliant status, which is superseded by ROHS3 in active production environments.

Selection Between GP-01 and GP-02: GP-01 offers expanded interface flexibility with GPIO, I2C, SPI, and UART options. GP-02 provides UART-only interface in a smaller 18-SMD package. Both support multi-constellation reception (GPS, GLONASS, GNSS), with GP-01 additionally supporting BeiDou.

Frequently Asked Questions (FAQ)

Q: Can GP-01 or GP-02 directly replace GPS-622F without PCB modifications?

A: Both substitutes are surface mount modules with identical operating temperature ranges and superior sensitivity. However, the voltage supply range differs: GPS-622F operates to 5.5V while substitutes operate to 3.6V maximum. If the original design uses supply voltages above 3.6V, power supply circuit modification is required. Package footprints differ (24-SMD for GP-01, 18-SMD for GP-02 versus module form for GPS-622F), requiring PCB layout evaluation.

Q: What is the sensitivity difference between GPS-622F and the substitutes?

A: GPS-622F provides -161dB sensitivity. GP-01 and GP-02 both provide -162dBm sensitivity, representing superior signal reception capability. This improvement enhances acquisition time and performance in weak signal environments.

Q: Do the substitute parts support GPS-only operation?

A: Yes. Both GP-01 and GP-02 include GPS protocol support as part of their multi-constellation capability. Designs requiring GPS-only reception can utilize either substitute; the additional GLONASS, GNSS, and BeiDou support does not interfere with GPS-only operation.

Q: What are the data interface differences?

A: GPS-622F uses PCB surface mount connection. GP-01 provides GPIO, I2C, SPI, and UART interfaces, offering design flexibility. GP-02 provides UART interface only. Selection depends on the host system communication protocol requirements.

Q: Are there inventory or lead time considerations?

A: GPS-622F is obsolete with 683 pieces in stock. GP-01 has 937 pieces in stock (active status). GP-02 has 628 pieces in stock (active status). For new designs, GP-01 and GP-02 represent active products with ongoing availability.

Q: What is the current consumption difference?

A: GPS-622F specifies 23mA receiving current. GP-01 and GP-02 do not specify receiving current in the provided parameters. Power budget analysis requires obtaining detailed current specifications from the respective manufacturers for precise power supply design.

Q: Are there package/case differences that affect assembly?

A: GPS-622F is specified as a Module. GP-01 is a 24-SMD Module. GP-02 is an 18-SMD Module. The SMD package designation indicates surface mount device configuration. PCB footprint and assembly process compatibility require evaluation against the specific module pinout and land pattern documentation.
