Engineering Selection Recommendations

Direct Electrical Equivalents (5VDC Operation):

The C&K BD06 operates at the same 5VDC voltage specification as the original 435668-5. This part provides increased current capacity (100mA versus 60mA), extended mechanical and electrical life (10,000 cycles versus 2,000 cycles), and ROHS3 compliance with MSL 1 rating. The BD06 is suitable for applications requiring the original voltage specification with enhanced reliability and regulatory compliance.

Higher Voltage/Current Capability Substitutes:

Grayhill Inc. 76PRB and 78 series parts (76PRB06ST, 76PRB06T, 78B06ST, 78B06T, 78RB06ST, 78RB06T) operate at 30VDC with 150mA current rating. These parts are suitable for applications requiring higher electrical capacity than the original specification. All Grayhill substitutes provide ROHS3 compliance and MSL 1 moisture sensitivity rating.

Actuator Type Selection:

Piano Actuator (76PRB series): Right-angle mounting configuration with raised actuator level (0.301" height). Available with tape seal washable feature (76PRB06ST) or standard configuration (76PRB06T).
Slide Actuator (78 series): Standard slide mechanism available in raised (78B06ST, 78B06T at 0.315" height) or flush/recessed (78RB06ST, 78RB06T at 0.265" height) configurations. Tape seal washable variants available (78B06ST, 78RB06ST).

Compliance and Packaging Considerations:

All substitute parts from Grayhill and C&K provide ROHS3 compliance and MSL 1 ratings, addressing regulatory requirements not applicable to the original TE Connectivity part. Grayhill parts are supplied in tube packaging; C&K BD06 is supplied in tube packaging. Washable variants with tape seal feature are available from Grayhill (76PRB06ST, 78B06ST, 78RB06ST) and C&K (BD06).

Product Status:

All substitute parts maintain Active product status, ensuring continued availability and support.

Frequently Asked Questions (FAQ)

Q: Can the Grayhill 76PRB06T or 78RB06T be used as direct replacements for the TE Connectivity 435668-5?

A: These parts are electrically compatible as SPST 6-position DIP switches with matching pitch (0.100"), termination style (PC Pin), and contact materials (Copper Alloy with Gold finish). However, they operate at 30VDC/150mA versus the original 5VDC/60mA specification. Substitution is valid only if the application circuit can accommodate the higher voltage and current ratings. Actuator type differs (Piano or Slide versus Rocker), requiring mechanical verification for PCB layout and enclosure fit.

Q: What is the difference between the Grayhill 78B06ST and 78RB06ST?

A: Both are 6-position SPST slide actuator DIP switches from Grayhill's 78 series operating at 30VDC/150mA. The primary difference is actuator height: 78B06ST has a raised actuator level (0.315" above board), while 78RB06ST has a flush/recessed actuator level (0.265" above board). Both include tape seal washable features. Selection depends on available PCB clearance and enclosure constraints.

Q: Is the C&K BD06 a suitable substitute for applications requiring 5VDC operation?

A: Yes. The C&K BD06 operates at 5VDC matching the original specification, with increased current capacity (100mA versus 60mA) and extended mechanical/electrical life (10,000 cycles versus 2,000 cycles). It provides ROHS3 compliance and MSL 1 rating. The slide actuator type and raised actuator level (0.297" height) differ from the original rocker actuator, requiring mechanical compatibility verification.

Q: What does the "ST" suffix indicate in Grayhill part numbers?

A: The "ST" suffix indicates the part includes tape seal washable features. Parts without this suffix (such as 76PRB06T, 78B06T, 78RB06T) do not include washable features. Selection depends on manufacturing process requirements and cleaning protocols.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts from Grayhill Inc. (76PRB and 78 series) and C&K (BD06) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The original TE Connectivity 435668-5 has RoHS status listed as Not Applicable.

Q: What is the difference between through-hole and through-hole right-angle mounting?

A: Through-hole mounting (78 series, BD06) positions the switch body perpendicular to the PCB with pins inserted vertically. Through-hole right-angle mounting (76PRB series) positions the switch body parallel to the PCB with pins inserted at a right angle. Right-angle configuration reduces PCB footprint height but requires different PCB layout design.

Q: Can I substitute a 30VDC-rated part in a 5VDC circuit?

A: Yes. A 30VDC-rated component operates safely at lower voltages. The Grayhill 76PRB and 78 series parts rated for 30VDC function correctly in 5VDC circuits. However, the reverse substitution (using a 5VDC-rated part in a 30VDC circuit) is not valid.

Q: What is the mechanical life difference between the original part and the C&K BD06?

A: The original TE Connectivity 435668-5 has 2,000 mechanical and electrical cycles. The C&K BD06 provides 10,000 mechanical and electrical cycles, representing a five-fold increase in rated operational life. This extended life rating applies to the same 0.100" pitch 6-position SPST configuration.
