Beyond op-amps: the COSINE power & interface map
COSINE’s substitution table spans far more than operational amplifiers. For buyers building a China-sourcing strategy, the power-management
and interface rows are where the biggest lead-time wins usually sit — LDOs, MOSFET drivers, PWM controllers, RS-485 / CAN transceivers,
comparators, voltage references and analogue switches.
The cross-reference below covers every COSINE power and interface part we list, linked to its live product page.

Frequently Asked Questions
Does COSINE replace LM29302 / IR2113 / SN65HVD1782?
Yes — COS29302 cross-references MIC29302 / LM29302 (LDO), COS2113 cross-references Infineon IR2113 (MOSFET driver), and COS485RS cross-references ADM4853 / SN65HVD1782 (RS-485). We stock the imported originals today and can cross-check COSINE availability for your BOM.
Which interface parts does COSINE cross-reference?
RS-485 / CAN transceivers (COS485RS, COS1042T), RS-232 (COSMAX3232), analogue switches (COS4514 / COS12A12511), transformer drivers (COS6501) and more. Tell us your interface BOM and we will map it.
Are these pages on your site now?
Yes — our live COSINE catalogue includes the LDO, MOSFET-driver, interface, reference and analogue-switch families listed below, each linking to its live product page. Contact us for any COSINE power / interface part not yet listed.
Cross-reference & compliance note
COSINE (科山芯创) cross-references on this page are compiled from the manufacturer’s published 2025 substitution list.
A cross-reference indicates functional / parametric equivalence in the stated package — it is not a guarantee of pin-to-pin compatibility.
Always verify the package, pinout and key electrical parameters against the original datasheet before substituting.
Shenzhen Jingteng Electronics is an independent distributor of COSINE and other brands. We are not an authorised agent of Analog Devices,
Texas Instruments, Microchip, Infineon, NXP, Maxim or any other original manufacturer; those brand names are used only to identify the parts being cross-referenced.
Parts shown in grey without a link are in our COSINE cross-reference catalogue but not yet on a live product page —
send us the exact part number and we will source it for you.
