Is there a pin-compatible replacement for HCZZ0323-5?

Currently, no replacement has been pre-verified as 100% pin-compatible. ZX-ZH1.5-5PWT is a strong candidate for being pin-compatible, but a manual check of the mechanical drawings in both datasheets is required to confirm the footprint and housing dimensions are identical.

What risks should I check before replacing HCZZ0323-5?

Before replacing HCZZ0323-5, you must check three key things: 1) The mechanical footprint on your PCB matches the substitute's datasheet. 2) The substitute's voltage and current ratings meet or exceed your application's requirements. 3) The housing dimensions will not interfere with other components or the enclosure.

HCZZ0323-5 Alternatives, Datasheet & Cross Reference | Shenzhen Hongcheng Electronics Co., Ltd.

HCZZ0323-5 is a 5-pin, 1.5mm pitch right-angle SMT header used for wire-to-board connections. While no drop-in replacement is confirmed, several functional alternatives exist from manufacturers like Megastar and JST that may be suitable after engineering review.

AI replacement insight

Package riskmedium

PCB footprint and housing dimensions must be verified from datasheets to ensure mechanical compatibility.

Electrical risklow

Top candidates have matching or better electrical ratings, but some alternatives have lower voltage limits.

Sourcing risklow

The ZH 1.5mm connector family is widely available from multiple manufacturers, reducing sourcing risk.

Can it be replaced directly?

There is no confirmed direct drop-in replacement for HCZZ0323-5. The candidate ZX-ZH1.5-5PWT is a strong functional match that requires engineering verification of its mechanical drawing and footprint before it can be considered pin-to-pin compatible.

Best replacement path

ZX-ZH1.5-5PWT by Megastar is the most promising alternative, offering matching form-factor and superior electrical ratings. However, its PCB footprint must be verified against the target's datasheet.

Main risk

The primary risk is the mechanical footprint. While pitch and pin count match, slight variations in housing or mounting peg dimensions can prevent a drop-in fit.

Recommended alternatives

A 5-pin, 1.5mm pitch SMT header with higher voltage and temperature ratings. Verify footprint before use.
