Substitute Part Grouping Explanation

Substitution eligibility for the AM-HRR30-433 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Frequency: 433MHz (exact match required)
• Modulation: AM (exact match required)
• Mounting Type: Through Hole (mechanical compatibility)
• Package Type: Module (form factor compatibility)

Secondary Compatibility Criteria:

• Voltage Supply Range: Must encompass or overlap with 4.5V ~ 5.5V
• Data Interface: PCB-compatible connection methods
• Operating Temperature Range: Must support -25°C ~ 85°C or broader range

The substitute part AM-RX9-433P meets the primary compatibility criteria by maintaining 433MHz frequency, AM modulation, through-hole mounting, and module packaging. The substitute demonstrates enhanced electrical performance characteristics while maintaining functional equivalence within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the AM-RX9-433P directly replace the AM-HRR30-433 in existing designs?

A: Yes. Both modules share identical frequency (433MHz), modulation (AM), mounting type (through hole), and package format (module). The substitute's supply voltage range encompasses the main part's requirements, and mechanical compatibility is maintained.

Q: What are the key differences between these two modules?

A: The AM-RX9-433P offers improved sensitivity (-109dBm vs. -105dBm), higher data rate capability (10kbps vs. 4.8kbps), wider supply voltage range (2.4V ~ 5.5V vs. 4.5V ~ 5.5V), and active product status versus obsolete status. Current consumption is comparable (2.6mA vs. 2.5mA).

Q: Does the higher data rate of the AM-RX9-433P affect compatibility?

A: No. The substitute's higher maximum data rate (10kbps) is a performance enhancement. Existing designs operating at 4.8kbps or lower will function without modification.

Q: Are there packaging differences between these modules?

A: Both modules use identical through-hole mounting and module packaging. No PCB layout modifications are required for substitution.

Q: What is the significance of the AM-HRR30-433 being obsolete?

A: Obsolete status indicates the manufacturer no longer produces this component. The AM-RX9-433P, classified as active, ensures continued availability and manufacturing support for new designs or replacement inventory.

Q: Does the AM-RX9-433P require different power supply specifications?

A: The substitute accepts a wider voltage range (2.4V ~ 5.5V). Existing power supplies delivering 4.5V ~ 5.5V remain fully compatible. The expanded lower voltage limit provides additional design flexibility.

Q: Are there compliance or certification differences?

A: The AM-RX9-433P carries ROHS3 compliance certification. The main part's REACH status is unaffected. Both components meet their respective regulatory requirements for their product status classifications.
