MH4516-102Y Ferrite Bead Equivalent & Substitute Parts

Part Overview

The MH4516-102Y is a 1 kOhm ferrite bead manufactured by Bourns Inc., designed for power and signal line filtering in 1806 (4516 Metric) surface mount packages. This component provides electromagnetic interference suppression with a maximum current rating of 1.5A and operates across the temperature range of -55°C to 125°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the MH4516-102Y is determined by strict equivalence across the following critical parameters:

• Impedance specification: 1 kOhms @ 100 MHz (exact match required)
• Current rating: 1.5A maximum (equal or greater acceptable)
• Package form factor: 1806 (4516 Metric) surface mount (exact match required)
• Number of lines: Single line configuration (exact match required)
• DC resistance: Maximum 150mOhm (equal or lower acceptable)
• Regulatory compliance: ROHS3 Compliant (minimum requirement)

Two substitute parts meet these criteria: HZ1806K102R-10 (Laird-Signal Integrity Products) qualifies as a direct manufacturer equivalent, and BLM41PG102SN1L (Murata Electronics) qualifies as a parametric equivalent with improved DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

HZ1806K102R-10 provides direct parametric equivalence to the MH4516-102Y with active product status and full ROHS3 compliance. This part maintains identical electrical specifications and mechanical form factor, making it suitable for direct replacement in existing designs. The operating temperature range of -40°C to 125°C covers most industrial and commercial applications, with the lower bound representing the primary distinction from the original part.

BLM41PG102SN1L offers an alternative with improved DC resistance performance (90mOhm versus 150mOhm), reducing power dissipation in the ferrite bead. This part maintains the required impedance, current rating, and package specifications. The operating temperature range of -55°C to 125°C matches the original part specification. The filter type designation as "Power Line" rather than "Power, Signal Line" reflects the component's primary application focus, though the electrical characteristics remain compatible with signal line filtering requirements.

Both substitutes carry active product status and are available in volume quantities, supporting production continuity and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can HZ1806K102R-10 be used as a direct replacement for MH4516-102Y?

A: Yes. HZ1806K102R-10 meets all critical electrical and mechanical parameters: 1 kOhms @ 100 MHz impedance, 1.5A current rating, 150mOhm maximum DC resistance, and 1806 (4516 Metric) surface mount package. The operating temperature range of -40°C to 125°C is suitable for most applications, with the exception of designs requiring operation below -40°C.

Q: What is the advantage of BLM41PG102SN1L over HZ1806K102R-10?

A: BLM41PG102SN1L provides lower DC resistance (90mOhm maximum versus 150mOhm), resulting in reduced power dissipation and heat generation. Both parts maintain identical impedance and current specifications. BLM41PG102SN1L also matches the original -55°C to 125°C operating temperature range.

Q: Are there packaging differences between these substitutes?

A: HZ1806K102R-10 is supplied in Tape & Reel (TR) format, while BLM41PG102SN1L is supplied in Cut Tape (CT) & Digi-Reel® format. Both are surface mount compatible with identical 1806 (4516 Metric) package dimensions: 0.177" L x 0.063" W (4.50mm x 1.60mm).

Q: Do all three parts meet RoHS compliance requirements?

A: Yes. MH4516-102Y, HZ1806K102R-10, and BLM41PG102SN1L are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Which substitute should be selected for new designs?

A: Selection depends on operating temperature requirements and power dissipation constraints. For applications requiring -55°C operation or lower power dissipation, BLM41PG102SN1L is preferred. For applications with -40°C minimum operating temperature, HZ1806K102R-10 provides equivalent performance with established supply availability.
