Shuntian
A brass M3 male-female standoff from the same manufacturer, but with a longer 16mm body.
The Shuntian M3x10+6Cu is a 10mm male-female hexagonal standoff with M3 threading, made of brass. Finding a direct replacement requires matching mechanical dimensions and material properties.
Body length is a critical dimension for fit.
High if used for grounding; Nylon is an insulator.
M3 standoffs are common, but finding an exact match may be difficult.
No direct, 1-to-1 replacement for the M3x10+6Cu has been identified. All potential substitutes have variations in body length or material.
Consider standoffs from the same manufacturer with different lengths, like M3x16+6Cu, if your design can accommodate the change. Otherwise, review nylon alternatives like TP-8 or TP-12A for non-conductive applications.
The main risks are mechanical interference from different body lengths and functional changes due to material differences (e.g., strength, conductivity).

|---|---|---|---|---|---|
| Body Length | 10 mm | 16 mm | 12 mm | 8 mm | 16 mm / 12 mm / 8 mm / 15 mm — Candidate is 6mm longer.; TP-12A: Candidate is 2mm longer.; TP-8: Candidate is 2mm shorter.; TP-15: Candidate is 5mm longer. |
| Material | Brass | Brass | Nylon 66 (UL94V-2) | Nylon 66 (UL94V-2) | Brass / Nylon 66 (UL94V-2) — matched; TP-12A: Affects strength and conductivity.; TP-8: Affects strength and conductivity.; TP-15: Affects strength and conductivity. |
| Thread Size | M3 | M3 | M3 | M3 | M3 — matched; TP-12A: matched; TP-8: matched; TP-15: matched |
| Type | Male-Female | Male-Female | Male-Female | Male-Female | Male-Female — Inferred from part number and attributes.; TP-12A: Inferred from attributes.; TP-8: Inferred from attributes.; TP-15: Inferred from attributes. |
Alternatives exist with different lengths or materials. For a similar brass part, M3x16+6Cu is an option if a 16mm body is acceptable. For different materials, nylon standoffs like TP-8 or TP-12A are available but require careful review.
