SMA versus RP-SMA

The center contact matters as well as the threaded outer shell.

Computer-generated illustration, not a photograph. — P063 · ConnectorSMA coaxial connector

How they differ

Compare the center-contact convention together with the threaded shell. RP-SMA does not mean reverse thread or electrically inverted signal.

Amphenol distinguishes the center-contact arrangement while retaining the threaded interface. S046 · S046 · S047
The cited RP-SMA jack has a standard-direction thread and a source-described male center pin. Shell naming alone is insufficient. S558 · S559

What this comparison does not establish: A cross-reference is not exact equivalence, and generic family names do not supply universal torque or performance. S559 · S510

Trace 7 claims to their source records

C063A · P063

SMA is a threaded RF connector family. Amphenol distinguishes SMA from RP-SMA by the center-contact arrangement even though the threaded interface is retained.

Claim scope: Named standard or manufacturer description only; procedural checks are editorial recommendations, not hardware tests.

Source links: S046 · Evidence trail → (private workspace)

C063C · P063

Amphenol RF gives different SMA tightening guidance for brass and stainless-steel configurations and directs readers to the particular drawing or datasheet. A generic SMA label is not enough to select a universal tightening value.

Claim scope: V121 named-product or explicitly scoped manufacturer distinction only; no wiring instruction, independent engineering approval or end-to-end compatibility guarantee.

Source links: S510 · Evidence trail → (private workspace)

C064A · P064

RP-SMA changes the center-contact arrangement relative to ordinary SMA while retaining the same threaded interface. The RP prefix is not a claim that a signal is electrically inverted.

Claim scope: Named standard or manufacturer description only; procedural checks are editorial recommendations, not hardware tests.

Source links: S046 · S047 · Evidence trail → (private workspace)

C064C · P064

Amphenol RF identifies 132134RP as a straight 50-ohm RP-SMA jack with PCB through-hole termination and soldered contact termination.

Claim scope: Exact part role and termination fields only; not a cable-crimp or panel-mount substitute.

Source links: S558 · Evidence trail → (private workspace)

C064D · P064

The 132134RP specification page describes the coupling as threaded and the thread direction as Standard.

Claim scope: The RP designation is not used as proof of a reversed thread direction. Thread dimensions and a mating-part approval are not supplied.

Source links: S558 · Evidence trail → (private workspace)

C064E · P064

TE’s cross-reference guide describes the Amphenol 132134RP entry as a jack with a male center pin.

Claim scope: The jack label and center-contact description are separate attributes. The exact Amphenol drawing remains uninspected; no shape or pin geometry is inferred.

Source links: S559 · Evidence trail → (private workspace)

C064F · P064

TE states that its cross-reference guide is for assessment and does not establish exact equivalence of competing products.

Claim scope: A listed relationship is not a replacement, quality, specification or approval verdict; application-specific analysis remains necessary.
