Reemplazo & Directrices de selección

1. Select the same 6038 tamaño, 24 VDC fan with tachometer speed feedback (FG signal) (p.ej., FFB0624EHE). If no fault alarm is required, a 2-wire standard 6038 24 VDC fan can be used, but inverters will trigger fan fault alarms.
2. Distancia entre orificios de montaje: Standard 50×50 mm for 60 mm fans.
3. Dirección del flujo de aire: Must match the intake/exhaust direction of the original fan.

Solución de problemas comunes

Fan does not spin: Controlar 24 Fuente de alimentación VCC, wiring harness and rotor jamming.

Fan runs but the drive reports a fan fault: Broken yellow tachometer wire or damaged Hall sensor inside the fan.

Ruido anormal: Worn ball bearings; direct replacement is required (ball bearing fans cannot be repaired after service life decay).

Mandatory requirements for direct interchange (failure to meet will trigger inverter fault alarms):

60×60×38 mm, 24 VCC, aprox. 0.4 A, 3-cable (Red +24V / Black GND / Yellow FG tachometer), dual ball bearings, open-collector rotor lock tach signal.

1. Preferred Domestic Drop-in Replacements (Grado industrial, Direct Pin-to-Pin Swap)

1) Dongxingyue (DXM, widely used for inverters)

Modelo: DF6038B24M-FG (3-wire with RD tach feedback)

Especulación: 24 VCC, 0.4~0.55 A, dual ball bearing, 7000~9000 RPM, FG tach output

Fully compatible with FFB0624SHE-R00; no wiring modification needed.

2) KAKU (KAKU, highest stability for industrial fans)

Modelo: KA6038B24H-FG

Especulación: 24 VCC, 0.42 A, 6038 tamaño, 3-wire speed detection, IP55 rating

Ideal for 24/7 operación continua; first choice for inverters and servo drives.

3) SNOWFAN (Cost-effective option)

Modelo: YY6038L24B-FG (3-wire tach version)

Especulación: 24 VCC, 0.38~0.42 A, dual ball bearing with FG signal

Importante: Only purchase the 3-wire FG tach model; avoid 2-wire non-feedback versions.

4) Yimeng (YM, commonly used for industrial power supplies)

Modelo: YM2406PTB3 (6038, 3-wire with feedback)

0.4 una corriente, 7000 RPM; pinout fully consistent with Delta fans.

1. General Alternative Models (Must specify: 3-cable + FG tach feedback when ordering)
2. Shengshida: 6038-24V-0.4A-FG
3. Weiyixin: RPM | 2-cable / 3-cable | Baja velocidad / Bajo nivel de ruido

III. Factory Upgrade Replacement (PFB0624 Series, In-Stock Direct Swap)

The FFB series is end-of-life; the corresponding Delta upgraded models are listed below:

1. FFB0624SHE-R00 → PFB0624SHE-R00 (3-wire with tach; pinout 100% compatible)
2. FFB0624EHE-R00 → PFB0624EHE-R00
3. Critical Purchase Notes
4. Inverter applications must select the -R00 (3-wire FG tach feedback) versión; 2-wire -F00 versions will cause fan fault alarms.
5. Fixed pin assignment: Red = +24 VCC, Black = GND, Yellow = FG tach signal.
6. If only FFB stock is available, prioritize FFB0624SHE-R00; if out of stock, switch directly to PFB0624SHE-R00.

Delta PFB0624 Series (6038 24 VCC) – Aplicaciones

Características principales: Dual ball bearings, grado industrial, alta presión estática, optional -R00 3-wire FG tach feedback. It is the direct upgraded replacement for the obsolete FFB0624 series, designed for forced air cooling inside sealed equipment. Models with tach feedback (-R00) are required for systems with fan fault monitoring.
