MA3216-601M4 Equivalent & Substitute Parts

Part Overview

The MA3216-601M4 is a 4-line ferrite bead array in 1206 (3216 Metric) surface mount package manufactured by Bourns Inc. This component provides 600 Ohms impedance at 100 MHz with a maximum current rating of 100mA and 500mOhm DC resistance. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitute parts for the MA3216-601M4 are qualified based on the following critical parameters:

Impedance matching at 100 MHz: 600 Ohms (exact match required)
Package compatibility: 1206 (3216 Metric), Array, 8 PC Pad (identical footprint and pad configuration)
Number of lines: 4 (same array configuration)
Operating temperature range: -55°C ~ 125°C (minimum requirement)
Surface mount technology (same mounting method)
RoHS3 compliance and MSL 1 rating (regulatory and handling compatibility)

All three substitute parts meet these core substitution criteria. Variations in current rating and DC resistance are within acceptable tolerances for this component category and do not prevent functional equivalence.

Engineering Selection Recommendations

All three substitute parts are active products with full RoHS3 compliance and MSL 1 rating, providing long-term availability and regulatory alignment compared to the obsolete MA3216-601M4.

BLA31AG601SN4D (Murata EMIFIL® series) offers the lowest DC resistance at 350mOhm, reducing insertion loss in signal paths. This part is suitable for applications where minimized impedance is beneficial.

BLA31BD601SN4D (Murata EMIFIL® series) provides a mid-range DC resistance of 450mOhm and is designated for signal line filtering applications. This part balances performance and general-purpose use.

ILAS1206ER601V (Vishay Dale ILAS-1206 series) matches the original 500mOhm DC resistance specification and provides double the current rating at 200mA. This part is suitable for higher current applications and direct functional replacement where current headroom is required.

All substitute parts maintain identical footprint, pad configuration, and operating temperature range, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for MA3216-601M4?

A: Yes. All three substitute parts share identical impedance (600 Ohms @ 100 MHz), package footprint (1206 3216 Metric), array configuration (4 lines, 8 PC Pad), and operating temperature range (-55°C ~ 125°C). They are electrically and mechanically compatible for PCB assembly without design changes.

Q: What is the difference between the Murata BLA31AG601SN4D and BLA31BD601SN4D?

A: Both are Murata EMIFIL® series parts with identical impedance and package specifications. The primary difference is DC resistance: BLA31AG601SN4D has 350mOhm while BLA31BD601SN4D has 450mOhm. BLA31BD601SN4D is designated for signal line filtering applications. Selection depends on your specific insertion loss requirements.

Q: Why does ILAS1206ER601V have a 200mA current rating while the original is 100mA?

A: The ILAS1206ER601V is rated for higher current capacity. This does not prevent substitution; it indicates the Vishay Dale part can handle greater current loads. If your circuit operates at or below 100mA, this higher rating provides additional design margin without affecting performance.

Q: Are there height differences I should consider for PCB assembly?

A: The original MA3216-601M4 has a maximum height of 0.035" (0.90mm). All three substitute parts have a maximum height of 0.039" (1.00mm). This 0.004" (0.10mm) difference is within standard PCB assembly tolerances and does not affect component placement or clearance in typical applications.

Q: Do all substitute parts have the same RoHS and MSL compliance?

A: Yes. All substitute parts are ROHS3 compliant and rated MSL 1 (Unlimited moisture sensitivity level), matching the original part's regulatory and handling requirements.
