Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM4343.301NLT is determined by strict equivalence across the following critical parameters:

• Inductance value: 300 nH with ±20% tolerance
• Current rating: 48 A continuous
• Saturation current: 72 A minimum
• DC resistance: 0.72 mOhm maximum
• Shielding configuration: Shielded construction
• Package dimensions: 14.00mm L x 12.80mm W x 6.50mm H (nonstandard)
• Mounting technology: Surface mount
• Operating temperature range: -40°C to 125°C
• Compliance: AEC-Q200 rated, ROHS3 compliant

The PA4343.301NLT meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical performance characteristics and mechanical compatibility, differing only in manufacturer series designation within the Pulse Electronics product line.

Parameter Comparison

Engineering Selection Recommendations

Both PM4343.301NLT and PA4343.301NLT are active production parts from Pulse Electronics with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on:

• Inventory availability: PA4343.301NLT offers significantly higher stock levels (3406 units versus 978 units)
• Supply chain continuity: Both parts maintain active production status
• Compliance requirements: Both satisfy automotive and industrial regulatory requirements
• Lead time considerations: Higher inventory of PA4343.301NLT may provide shorter procurement cycles

No electrical or mechanical performance differentiation exists between these parts. PCB layout, thermal management, and circuit integration remain unchanged when substituting between them.

Frequently Asked Questions (FAQ)

Q: Are PM4343.301NLT and PA4343.301NLT electrically identical?

A: Yes. Both parts have identical inductance (300 nH), current rating (48 A), saturation current (72 A), and DC resistance (0.72 mOhm max). Electrical performance is equivalent across all specified parameters.

Q: Can PA4343.301NLT be used as a direct replacement for PM4343.301NLT in existing designs?

A: Yes. The parts share identical package dimensions (14.00mm x 12.80mm x 6.50mm), mounting type (surface mount), and operating temperature range (-40°C to 125°C). No PCB redesign or component repositioning is required.

Q: What is the difference between the PM4343 and PA4343 series?

A: Both are Pulse Electronics shielded molded inductor series with identical electrical and mechanical specifications. The series designation difference reflects internal product line organization but does not affect performance or compatibility.

Q: Are both parts AEC-Q200 qualified?

A: Yes. Both PM4343.301NLT and PA4343.301NLT carry AEC-Q200 automotive qualification and are ROHS3 compliant with MSL 1 moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. PA4343.301NLT offers higher inventory availability (3406 units), which may provide supply chain advantages. Both maintain active production status.

Q: Are there any thermal or frequency performance differences?

A: No. Both parts operate across the same temperature range (-40°C to 125°C) and are tested at 100 kHz. Thermal and frequency characteristics are identical.
