PJ-5410-CB1 is an SMT 4-pole waterproof jack candidate with missing key checks.
PJ-313D replacement choices should be treated as review-required because target pin count and footprint data are missing.
Voltage type and temp coverage vary.
Footprint evidence is missing.
Passive connector only.
PDF checks are pending.
No pin-compatible replacement is confirmed from the provided evidence.
Start with SMT candidates, then verify pinout, land pattern, ratings, and jack contact scheme.
Pinout and footprint are not proven.

| Feature / factor | PJ-313D | HC-PJ-313E8-B-SMT | PJ-5410-CB1 | HC-PJ-320A | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SMD | SMT | SMT | Through Hole | SMT / Through Hole — Mount class aligns; PJ-5410-CB1: Mount class aligns; HC-PJ-320A: PCB change likely |
| Pinout | missing | 8 pins | missing | 4 pins | 8 pins / missing / 4 pins — No pin map; PJ-5410-CB1: No pin data; HC-PJ-320A: No pin map |
| Voltage | 30V DC | 30 VAC | missing | 30V RMS | 30 VAC / missing / 30V RMS — Rating type differs; PJ-5410-CB1: Must confirm; HC-PJ-320A: Rating type differs |
| Current | 0.5A | 0.5A | 1A | 0.5A | 0.5A / 1A — Same nominal; PJ-5410-CB1: Higher listed; HC-PJ-320A: Same nominal |
| Temperature | -30 to 70C | -25 to 70C | missing | -25 to 70C | -25 to 70C / missing — Cold limit weaker; PJ-5410-CB1: Must confirm; HC-PJ-320A: Cold limit weaker |
HC-PJ-313E8-B-SMT is the closest listed SMT candidate, but it still needs pinout and footprint review.
