About the series
What it is
The A1-CONNECT SNP339 series is an equivalent of the СНП339 series (rectangular low-frequency miniature high-density connectors for flat (ribbon) cables and hook-up wires, plug-in (blade) mating with screw locking and a keying element). 21, 42, 50, 52, 54, 76 contacts in two rows on 1.25 mm pitch; plugs with a metal hood and a shielded (P1/P2) or plastic (Q1/Q2) cable outlet; front-mount (Q) and rear-mount (H) receptacles; 12 key positions. Manufacturer's versions: SNP339.
Stated compatibility
The manufacturer states that SNP339 is interchangeable and intermateable with the СНП339 series: 1.25 mm pitch, the same 21…76 contact range, produced to company standard Q/3E20032-2006, declared equivalent to ЦСНК.430421.004 ТУ. The shielded version (metal hood, shielded straight cable outlet) replaces hooded СНП339; the unshielded micro version replaces СНП339 and СНП378 (SNP378) (for example, CFC2-52THJ corresponds to СНП378-52БП11, and CFC2-52ZHJ to СНП378-52РП11). The contacts are resilient twisted pins (twist-pin type).
Where it is used
The same applications as СНП339: inter-unit and cable connections in equipment for industrial automation, instrumentation, transportation, power engineering and telecommunications — within the operating conditions listed in the specifications.
What it replaces and what to check
Replaces СНП339 per the equivalent manufacturer's cross-reference table. Before replacement, verify the mounting footprint, contact arrangement, mating part (within the same system), contact plating and temperature range against the drawings of both series; samples are available from 1 piece.
CFC2-52THJP1-1FH: SNP339 — series (CFC — the СНП series, 2 — design number 339/378); 52 — number of contacts; T — plug (pins, original Б) / Z — receptacle (sockets, original Р); H — point-to-point wire soldering (original П1); J — gold (original 1) / Y — silver (original 2); cable outlet: P1 — shielded straight with clamp (original 2), P2 — short shielded without key (original 7), Q1 — straight plastic (original: no digit), Q2 — plastic with threaded locks (original 8); 1…12 — key position; F — electroless nickel plating (original Т) / W — cadmium plating; Q — front (original б) / H — rear (original а) receptacle mounting.

Questions and answers
How does A1-CONNECT SNP339 replace СНП339?
The manufacturer states that SNP339 is interchangeable and intermateable with the СНП339 series: 1.25 mm pitch, the same 21…76 contact range, produced to company standard Q/3E20032-2006, declared equivalent to ЦСНК.430421.004 ТУ. The shielded version (metal hood, shielded straight cable outlet) replaces hooded СНП339; the unshielded micro version replaces СНП339 and СНП378 (for example, CFC2-52THJ corresponds to СНП378-52БП11, and CFC2-52ZHJ to СНП378-52РП11).
What parameters are needed for selection?
The part number of the item being replaced, or the number of contacts, current and voltage per contact, coupling type, temperature range and IP rating, side (plug or receptacle) and termination method.
Can I get samples?
Yes, samples from 1 piece to verify mating and the mounting footprint; volume supply is per your bill of materials.
