Model Finder — Find the HGCHIPS Drop-in Replacement

Type an original part number (e.g. K4B4G1646E-BCMA, H5AN8G6NCJR-XNC, MT40A512M16JY-075E, LTM4644) or an HGCHIPS part number (e.g. HGD34G16S18) to locate the drop-in replacement, specifications and detail page. The database covers 244 production part numbers (including 11 Micron DDR3-1866/2133 spec-matched parts whose production status is confirmed by our FAE) plus 80 ADI µModule models in engineering validation (engineering samples available), mapped to 324 original part numbers in total (including 29 Micron DDR3-1866/2133 parts) from Samsung, SK Hynix, Micron, Nanya and ADI.

How to use the Model Finder

The finder moves you from an original manufacturer part number to a pin-to-pin compatible part we hold in stock, and then to the datasheet or a quotation.

Four steps

• Enter the original part number and manufacturer (for example Samsung K4B4G1646E-BCMA or Micron MT41K256M16TW-107)
• Check the package and ball count against your board footprint
• Compare the electrical and timing parameters in the cross-reference table
• Download the datasheet, or request a quotation and a sample quantity

What a result tells you

• Original part number → our part number: the part we supply for that position
• Package and ball count: the footprint the part drops into
• Density, speed and voltage: the parameters we guarantee in the datasheet
• Pin-to-pin: whether the ball map is a direct match or needs board attention
• Stock and lead time: in-stock items dispatch within 48 hours; made-to-order items are quoted with a lead time

FAQ

My part number is not in the finder. What happens next?

Send it to us. We check the original datasheet, the package and the ball-out, and come back within one business day with either a drop-in candidate or a clear statement that we cannot support it. We do not quote a part we cannot verify.

Is the replacement really pin-to-pin?

For the families we list, the ball map and land pattern are verified against the original datasheet. Where a parameter differs, we state it in the cross-reference table instead of hiding it.

What documentation do I receive with a quotation?

A cross-reference table (original part number versus our part number), the datasheet, and a per-batch test report. Failure-analysis data is available on request for qualified projects.

Are the listed prices binding?

No. Prices in the stock finder are indicative reference prices for budget planning. Final pricing is confirmed in the contract, based on quantity, delivery terms and date.
