Selection priorities

Define the key engineering inputs

01

State HMS31 threaded, HMS31 K or HMS31 KY

02

Include all available prefixes, suffixes and keying codes

03

Provide the current drawing, specification or catalog revision

04

Identify receptacle/plug and mounting form from the selected record

05

State threaded or reverse-bayonet connection from the selected record

06

State solder or crimp from the selected record

07

Provide shell size and insert arrangement

08

Provide contact gender, key position and polarization details

Project fit

Application and configuration review

Each record retains its own connection method, termination, ordering data, drawings, applications and unresolved claims.

| | HMS31 threaded parent/base record | Threaded; solder contacts in the product source | Compliance Review only | Formal taxonomy, current part numbers, qualification, application and export boundary |

| | HMS31 K independent child record | Reverse bayonet; solder contacts in the product source | project inquiry only for a clear ordinary industrial/civil model and end use; otherwise Compliance Review | Formal relationship to , current part numbers, mating scope, qualification and export boundary |

Threaded , solder-contact K and crimp-contact KY are not merged into one technical specification.

1. Start with the exact source record: , K or KY.

Frequently asked questions

Plan the next engineering step

Is the manufacturer-confirmed parent of HMS31 K and HMS31 KY?

Not on the present evidence. is the project’s internal parent/base node, while K and KY remain separate records. Written manufacturer confirmation is still required for a formal taxonomy.

Why does use Compliance Review while K and KY can sometimes use project inquiry?

is retained as a parent-level compliance record. K and KY may use project inquiry only for a clearly identified ordinary industrial or civil model and end use; sensitive, controlled or unclear use escalates to Compliance Review.

Can an HMS31 K or KY page bypass the parent compliance review?

No. Route selection follows the exact model, final user, final use, platform and destination.

Can , K and KY technical values be combined?

No. Threaded , solder-contact K and crimp-contact KY retain separate ordering data, electrical fields, drawings and accessories.

Do the product standards or interchange statements prove compatibility or qualification?

No. They record what the product pages stated. Certification, QPL/QPD status, mating, compatibility, interchangeability and project approval each require their own current evidence.

What should be submitted for a family or cross-reference review?

Provide the exact record and part number, both mating drawings, insert and keying details, termination, electrical and environmental requirements, final user, final use, destination and a validation plan.
