Substitute Part Grouping Explanation

Substitution eligibility for the HMR3400 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Honeywell Aerospace
• Series: HMR
• Type: Digital Compass
• Axis Configuration: X, Y, Z (3-Axis)
• Measuring Range: ±2 Gauss, ±60°
• Resolution: 100µGauss, 0.1°
• Measurement Capability: Heading, Pitch and Roll
• Interface: UART, SPI
• Operating Temperature Range: -20°C ~ 70°C (TA)
• Package Type: Module (No Case)
• Moisture Sensitivity Level: 1 (Unlimited)

The HMR3300 meets all mandatory matching parameters and qualifies as a direct substitute for the HMR3400. Both components share identical electrical specifications, mechanical packaging, and environmental operating conditions.

Parameter Comparison

Engineering Selection Recommendations

HMR3300 as Primary Substitute:

The HMR3300 is the direct equivalent substitute for the HMR3400. All electrical, mechanical, and environmental parameters are identical. The HMR3300 maintains active product status with Honeywell Aerospace, ensuring ongoing availability and supply chain support.

Compliance Considerations:

Both the HMR3400 and HMR3300 carry identical RoHS non-compliant status and share the same ECCN (7A994) and HTSUS (9014.10.9000) classifications. Systems utilizing either component must account for these regulatory designations in procurement and deployment documentation.

Availability:

The HMR3300 is currently in active production with 1075 pieces available as new original stock, compared to the HMR3400's obsolete status with 1013 pieces remaining in inventory. For new designs or ongoing production requirements, the HMR3300 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the HMR3300 directly replace the HMR3400 in existing designs?

A: Yes. The HMR3300 is electrically and mechanically equivalent to the HMR3400. All interface protocols (UART, SPI), measurement ranges, resolutions, and operating temperature specifications are identical. No design modifications are required for substitution.

Q: What is the difference between the HMR3400 and HMR3300?

A: The primary difference is product status. The HMR3400 is obsolete, while the HMR3300 is active. All functional and electrical parameters are identical. The HMR3300 represents the current production equivalent.

Q: Are there any compliance differences between these parts?

A: No. Both components share identical RoHS status (non-compliant), ECCN classification (7A994), and HTSUS code (9014.10.9000). Compliance documentation requirements are the same for both parts.

Q: What does "Module (No Case)" packaging mean?

A: Both the HMR3400 and HMR3300 are supplied as bare modules without external housing or protective casing. Integration into system-level enclosures or protective housings is the responsibility of the end user or system integrator.

Q: Are the interface protocols identical?

A: Yes. Both components support UART and SPI communication interfaces. Firmware, driver, and protocol implementations developed for the HMR3400 are directly compatible with the HMR3300.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special humidity control requirements.
