What risks should I check before replacing SM06B-SURS-TF(LF)(SN)?

The main risk is mechanical fit. Check the candidate's datasheet for the exact footprint, height, and shroud dimensions. Also, confirm the current/voltage ratings and operating temperature meet your design requirements.

SM06B-SURS-TF(LF)(SN) Alternatives, Datasheet & Cross Reference | JST

Reviewing alternatives for the JST SM06B-SURS-TF(LF)(SN), a 6-pin 0.8mm pitch side-entry SMT header. Key considerations for substitutes are matching the side-entry mounting and verifying the mechanical footprint.

AI replacement insight

Package riskhigh

Footprint and orientation must be verified from datasheets.

Electrical risklow

Candidates have matching or better electrical ratings.

Sourcing riskmedium

Availability of alternatives may vary by region.

Can it be replaced directly?

Direct replacement for SM06B-SURS-TF(LF)(SN) should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The strongest path is a form-fit-function alternate like HCZZ0536-6, which matches key electricals and mounting style, but requires careful datasheet review to confirm the PCB footprint.

Main risk

The primary risk is mechanical incompatibility. Mismatches in footprint, orientation (vertical vs. side-entry), or shroud dimensions can prevent assembly.

Recommended alternatives

Functionally similar with same pitch and pin count, but has a different (vertical) mounting orientation.
