If your device is compatible with SDHC, you can also use SD card, but if it is only compatible, you probably cannot use SDHC card.

About Micro SDHC

Four-bit SD bus mode: Uses extra pins plus some reassigned pins. This is the same protocol as the one-bit SD bus mode which uses one command and four data lines for faster data transfer. All SD cards support this mode. UHS-I and UHS-II require this bus type. The power consumption of SD cards varies by its speed mode, manufacturer and model. [ citation needed] The microSDHC can be used on devices including telephones, tablets, action cameras, 360-degree cameras, and drones. The micro SDHC host devices are asked to accept older SD cards, which indicates that the older SD cards with new technologies can comply with an SDHC device. Compatibility The maximum read and write speed of the microSD card is 25MB/s. Considering its small size, this speed is pretty fast. Compared with the microSD card, the microSDHC card has a higher transfer rate ranging from 50MB/s to 150MB/s. Again, most of the information had already been discovered and Linux had a fully free driver for it. Still, building a chip conforming to this specification caused the One Laptop per Child project to claim "the first truly Open Source SD implementation, with no need to obtain an SDI license or sign NDAs to create SD drivers or applications."

Capacity of less than 32,680 logical sectors (smaller than 16 MB [i]): FAT12 with partition type 01h and BPB 3.0 or EBPB 4.1 [158]
As for price, the SDXC card is more expensive than that of the SDHC card. When you select the SDXC card features same storage capacity and speed capacity to the SDHC card, you will cost more money. At the 2000 Consumer Electronics Show (CES), the three companies announced the creation of the SD Association (SDA) to promote SD cards. The SD Association, which was headquartered in San Ramon, California, United States, then had 30 member companies and product manufacturers that made interoperable memory cards and devices. Early samples of the SD card [8] became available in the first quarter of 2000, and production quantities of 32 and 64 megabyte (MB) [a] cards became available three months later.

There’s no absolute answer. Instead, it depends on your need and preference.
Both the microSD and microSDHC cards are most commonly used in mobile electronics like cell phones and tablets. In the definition of SDHC cards in version 2.0, the C_SIZE portion of the CSD is 22 bits and it indicates the memory size in multiples of 512KB (the C_SIZE_MULT field is removed and READ_BL_LEN is no longer used to compute capacity). Two bits that were formerly reserved now identify the card family: 0 is SDSC; 1 is SDHC or SDXC; 2 and 3 are reserved. [84] Because of these redefinitions, older host devices do not correctly identify SDHC or SDXC cards nor their correct capacity.

In April 2012, Panasonic introduced MicroP2 card format for professional video applications. The cards are essentially full-size SDHC or SDXC UHS-II cards, rated at UHS Speed Class U1. [28] [29] An adapter allows MicroP2 cards to work in current P2 card equipment. [30]

Types of SD cards
Samsung announced the world's first EVO Plus 256GB microSDXC card in May 2016, [36] and in September 2016 Western Digital (SanDisk) announced that a prototype of the first 1 TB [c] SDXC card would be demonstrated at Photokina. [37] Micro SDHC are the same size as standard Micro SD cards with storage capacity ranging from 4GB to 32GB. Micro SDXC are the higher capacity version of the SDHC cards with storage capacity ranging from 64GB all the way up to 2TB. Speed of Micro SDHC and SDXC SDHC cards are physically and electrically identical to standard-capacity SD cards (SDSC). The major compatibility issues between SDHC and SDSC cards are the redefinition of the Card-Specific Data (CSD) register in version 2.0 (see below), and the fact that SDHC cards are shipped preformatted with the FAT32 file system.
