Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BLM02AX700SN1D is determined by the following critical parameters: package type (01005/0402 Metric), mounting method (Surface Mount), operating temperature range (-55°C ~ 125°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

The identified substitute parts maintain compatibility within these core mechanical and regulatory constraints. Electrical parameters including impedance at 100 MHz, current rating, and DC resistance define the functional performance envelope. Parts with identical or superior electrical specifications within the same package and mounting classification are classified as direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

MMZ0402S700CT000 (TDK Corporation) provides direct electrical and mechanical equivalence to the BLM02AX700SN1D. Both components deliver 70 Ohms impedance at 100 MHz, 300mA current rating, and 360mOhm DC resistance in identical 01005 package geometry. All regulatory certifications (ROHS3, REACH Unaffected, EAR99) align. This substitute is suitable for direct replacement in applications where Murata and TDK sourcing are interchangeable.

BLM02PX600SN1D (Murata Electronics) offers enhanced current handling capability at 500mA versus 300mA, with reduced DC resistance of 250mOhm. The impedance specification differs at 60 Ohms versus 70 Ohms at 100 MHz. This part remains within the same manufacturer family and package class. Selection of this substitute requires confirmation that the lower impedance value and higher current capacity align with circuit requirements.

All substitute parts maintain Active product status and identical compliance profiles, ensuring long-term availability and regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can BLM02PX600SN1D replace BLM02AX700SN1D in all applications?

A: BLM02PX600SN1D differs in impedance (60 Ohms vs. 70 Ohms at 100 MHz) and current rating (500mA vs. 300mA). Substitution is valid only when the circuit design accommodates the lower impedance specification and does not require the original 300mA current limit as a constraint.

Q: Is MMZ0402S700CT000 a direct equivalent?

A: Yes. MMZ0402S700CT000 matches all critical electrical parameters (70 Ohms @ 100 MHz, 300mA, 360mOhm) and mechanical specifications (01005 package, surface mount, identical dimensions). Regulatory compliance is identical across ROHS3, REACH, and ECCN classifications.

Q: Are there package or mounting differences between these substitutes?

A: No. All three parts use 01005 (0402 Metric) surface mount packaging with identical dimensions (0.016" L x 0.008" W / 0.40mm x 0.20mm) and maximum height (0.009" / 0.22mm).

Q: What is the operating temperature range for all substitutes?

A: All parts operate across -55°C to 125°C, ensuring thermal compatibility across standard industrial and commercial applications.

Q: Are all substitutes RoHS and REACH compliant?

A: Yes. BLM02AX700SN1D, BLM02PX600SN1D, and MMZ0402S700CT000 are all ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.
