Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMZ2012Y150BT000 is determined by the following critical parameters:

Primary Substitution Criteria:

• Impedance @ 100 MHz: 15 Ohms (exact match required for signal integrity)
• Current Rating: Minimum 1.5A
• DC Resistance: Maximum 50mOhm
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
• RoHS Compliance: ROHS3 Compliant
• Mounting Type: Surface Mount

Secondary Considerations:

• Package form factor (0805/2012 Metric preferred for direct PCB compatibility)
• Number of Lines: Single line configuration
• Moisture Sensitivity Level: 1 (Unlimited)

Two substitute parts meet these criteria with varying degrees of compatibility:

1. MMZ1608Y150BTA00 (TDK Corporation) - MFR Recommended: Identical electrical specifications with reduced package size (0603/1608 Metric)
2. ACML-0805-170-T (Abracon LLC) - Parametric Equivalent: Maintains 0805 package with impedance variance (17 Ohms) and elevated current rating (2A)

Parameter Comparison

Engineering Selection Recommendations

MMZ1608Y150BTA00 (TDK Corporation) is the preferred substitute when design constraints permit package size reduction. This part maintains identical electrical specifications (15 Ohms @ 100 MHz, 1.5A, 50mOhm DCR) and is manufactured by the original supplier. Active product status ensures long-term availability. The 0603 (1608 Metric) package occupies 20% less board space than the original 0805 form factor. PCB layout modification is required for direct substitution.

ACML-0805-170-T (Abracon LLC) provides direct package compatibility (0805/2012 Metric) without PCB redesign. This part maintains the same physical footprint and height profile as the original MMZ2012Y150BT000. The impedance specification of 17 Ohms represents a 13% increase from the original 15 Ohms, and current rating is elevated to 2A. Selection of this part requires circuit-level analysis to confirm impedance tolerance acceptance. Active product status and full compliance certifications support production continuity.

Both substitutes are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) and identical operating temperature ranges (-55°C ~ 125°C).

Frequently Asked Questions (FAQ)

Q: Can MMZ1608Y150BTA00 be used as a direct drop-in replacement?

A: Electrical specifications are identical, but the 0603 (1608 Metric) package is smaller than the original 0805 (2012 Metric). Direct PCB footprint substitution is not possible without layout modification. The part requires new pad design and placement adjustment.

Q: What is the impedance tolerance impact of using ACML-0805-170-T?

A: The ACML-0805-170-T operates at 17 Ohms @ 100 MHz versus the original 15 Ohms specification. This 2-Ohm difference (13% variance) must be evaluated within your circuit's filtering requirements and signal integrity margins. Impedance mismatch may affect attenuation characteristics in the target frequency band.

Q: Are both substitutes compatible with existing assembly processes?

A: MMZ1608Y150BTA00 requires PCB redesign due to package size reduction. ACML-0805-170-T maintains identical 0805 (2012 Metric) package dimensions and surface mount characteristics, allowing assembly process continuation without modification.

Q: What is the inventory status for each substitute?

A: MMZ1608Y150BTA00 has 24,223 pieces in stock (Active status). ACML-0805-170-T has 3,920 pieces in stock (Active status). Both parts support sustained production requirements.

Q: Do all parts meet the same compliance standards?

A: Yes. MMZ2012Y150BT000, MMZ1608Y150BTA00, and ACML-0805-170-T are all ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8548.00.0000. Moisture Sensitivity Level is 1 (Unlimited) for all three parts.

Q: Which substitute should be selected for new designs?

A: For new designs without PCB constraints, MMZ1608Y150BTA00 is recommended due to identical electrical specifications, smaller footprint, and active TDK product status. For existing designs requiring minimal modification, ACML-0805-170-T provides package compatibility with impedance variance consideration.
