Substitute Part Grouping Explanation

Substitution analysis for the HMC750LP4ETR is based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Manufacturer: Analog Devices Inc. (same manufacturer ensures design continuity and quality standards)
• Amplifier classification and functional category
• Supply voltage compatibility range
• Current consumption specifications
• Operating temperature range
• Surface mount packaging capability
• Export classification (ECCN) and tariff code (HTSUS) alignment

The HMC865LC3 is identified as a manufacturer-recommended substitute. While this part operates in a different functional category (RF Amplifier General Purpose versus Limiting Amplifier), it shares the same manufacturer, export classification, and tariff code. The substitute part is currently in active production status, addressing the obsolescence issue of the primary part.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The HMC750LP4ETR is classified as obsolete. The HMC865LC3 is in active production status, ensuring long-term availability and supply chain stability for new designs and production continuity.

Compliance and Certification: Both parts share identical export classification (EAR99) and tariff code (8542.33.0001), ensuring regulatory alignment for international distribution and procurement. The HMC865LC3 carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements.

Supply Voltage Differential: The HMC750LP4ETR operates within a 4.6 V to 5.4 V supply range, while the HMC865LC3 operates within a 3.13 V to 3.47 V range. These ranges do not overlap, requiring circuit redesign considerations for power supply architecture.

Current Consumption: The HMC865LC3 demonstrates lower supply current (90 mA) compared to the HMC750LP4ETR (106 mA), resulting in reduced power dissipation and thermal management requirements.

Moisture Sensitivity: The HMC750LP4ETR carries MSL 1 (Unlimited), while the HMC865LC3 carries MSL 3 (168 Hours). This difference affects storage, handling, and reflow soldering procedures during manufacturing.

Frequently Asked Questions (FAQ)

Q: Can the HMC865LC3 be used as a direct pin-for-pin replacement for the HMC750LP4ETR?

A: No. The HMC750LP4ETR uses a 24-QFN (4x4) package, while the HMC865LC3 uses a 16-CSMT (3x3) package. These packages have different pin counts, pinout configurations, and physical dimensions, requiring circuit board redesign.

Q: What is the primary reason for substituting the HMC750LP4ETR?

A: The HMC750LP4ETR is classified as obsolete. The HMC865LC3 is an active production part from the same manufacturer, ensuring continued availability and supply chain support.

Q: Are there supply voltage compatibility issues between these parts?

A: Yes. The HMC750LP4ETR requires 4.6 V to 5.4 V supply voltage, while the HMC865LC3 requires 3.13 V to 3.47 V. These ranges are non-overlapping and require separate power supply circuits or voltage regulation modifications.

Q: How do the functional categories differ between these parts?

A: The HMC750LP4ETR is a limiting amplifier with differential output designed for single-channel applications. The HMC865LC3 is a general-purpose RF amplifier. These represent different functional classifications within the amplifier category.

Q: What are the moisture sensitivity implications for manufacturing?

A: The HMC750LP4ETR (MSL 1) has unlimited shelf life under controlled conditions. The HMC865LC3 (MSL 3) requires baking and reflow within 168 hours of package opening, imposing stricter manufacturing process controls and inventory management.

Q: Are both parts compliant with current environmental regulations?

A: The HMC865LC3 carries ROHS3 compliance and REACH Unaffected status. The HMC750LP4ETR compliance status is not specified in the provided data. Both parts share identical export classification (EAR99) and tariff code (8542.33.0001).
