Parameter Comparison

Engineering Selection Recommendations

Both the 4590-156K and 4590R-156K are active production components from API Delevan Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements:

The 4590-156K is RoHS non-compliant and suitable for applications without RoHS mandates. The 4590R-156K achieves ROHS3 compliance, making it the appropriate choice for designs requiring adherence to RoHS3 standards or for supply chains with RoHS compliance requirements. Both parts maintain REACH Unaffected status and EAR99 export classification.

Inventory availability favors the 4590R-156K with 1546 units in stock compared to 826 units for the 4590-156K.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-156K replace the 4590-156K in existing designs?

A: Yes. The 4590R-156K is electrically and mechanically identical to the 4590-156K across all specified parameters including inductance, current rating, DC resistance, core material, temperature range, and physical dimensions. Direct substitution is valid.

Q: What is the primary difference between these two parts?

A: The 4590R-156K is ROHS3 compliant while the 4590-156K is RoHS non-compliant. All electrical and mechanical characteristics remain identical.

Q: Are there any dimensional or mounting differences?

A: No. Both parts share identical axial through-hole packaging with dimensions of 0.455" Dia x 0.900" L (11.55mm x 22.86mm). PCB layout and mounting procedures are unchanged.

Q: What inductance tolerance applies to both parts?

A: Both the 4590-156K and 4590R-156K carry a ±10% inductance tolerance at 1 kHz test frequency.

Q: Are there temperature range limitations for either part?

A: Both parts operate identically across the -55°C to 125°C temperature range with no derating required within this specification.

Q: Which part should be selected for new designs?

A: Selection depends on compliance requirements. For RoHS3-compliant applications, specify the 4590R-156K. For applications without RoHS mandates, either part is acceptable based on availability and cost considerations.
