About the series
What it is
The A1-CONNECT GRPM1 series is an analog of the ГРПМ1 / ГРПМШ-1 (GRPM1 / GRPMSh-1) series (rectangular low-frequency PCB connectors, two-row, 3.5 mm pitch, plug-in mating). GRPM1: 31, 45, 61, 90, 122 contacts; CFSMW1: 31, 45, 61 contacts; two plug tail styles (right-angle Y, straight H) plus off-board wire termination O. Manufacturer's versions: GRPM1 (analog of ГРПМ1) and CFSMW1 (analog of ГРПМШ1).
Compatibility claims
The manufacturer maintains two separate series: GRPM1 is declared fully interchangeable and intermateable with ГРПМ1 (specification КЕО.364.006ТУ, range of 31, 45, 61, 90, 122 contacts), CFSMW1 — fully interchangeable and intermateable with ГРПМШ1 (НЩО.364.016ТУ, 31, 45, 61 contacts); the design description mirrors the original: guides, pin contacts fixed in the insulator, “floating” socket contacts, solder termination.
Where it is used
The same applications as ГРПМ1 / ГРПМШ-1: inter-unit and cable interconnections of equipment in industrial automation, instrumentation, transportation, power engineering and telecommunications — within the operating conditions listed in the specifications.
What it replaces and what to check
Replacement for ГРПМ1 / ГРПМШ-1 per the cross-reference table of the analog's manufacturer. Before replacing, verify the 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.
CFSM1-31JY2B (ГРПМ1-31ШУ2В) and CFSMW1-31JY2B (ГРПМШ1-31ШУ2В): GRPM1/CFSMW1 — series; 31 — number of contacts; J — pin (Ш), K — socket (Г); Y — right-angle mounting (У), H — straight (П), O — off-board wire termination (О); 2 — silver-plated contacts; B — all-climate version

Questions and answers
How does A1-CONNECT GRPM1 replace ГРПМ1 / ГРПМШ-1?
The manufacturer maintains two separate series: GRPM1 is declared fully interchangeable and intermateable with ГРПМ1 (specification КЕО.364.006ТУ, range of 31, 45, 61, 90, 122 contacts), CFSMW1 — fully interchangeable and intermateable with ГРПМШ1 (НЩО.364.016ТУ, 31, 45, 61 contacts); the design description mirrors the original: guides, pin contacts fixed in the insulator, “floating” socket contacts, solder termination.
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 samples be obtained?
Yes, samples from 1 piece to verify mating and footprint; volume supply is per your BOM.
