CTS Electrocomponents 210-4LPSF DIP Switch Equivalent & Substitute Parts

Part Overview

The CTS Electrocomponents 210-4LPSF is a 4-position DIP switch with SPST circuit configuration, rated for 100mA at 20VDC. This through-hole mounted component features a slide actuator with flush/recessed level, beryllium copper contacts with gold finish, and epoxy sealed terminals. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: SPST circuit topology, 4-position configuration, 100mA current rating, through-hole mounting with 0.100" pitch, and compatible actuator types. Substitute models from C&K Electronics offer enhanced operational characteristics while maintaining functional compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 210-4LPSF is determined by the following mandatory parameters:

• Circuit configuration must be SPST
• Position count must be 4
• Current rating must be 100mA or greater
• Voltage rating must be 20VDC or greater
• Actuator type must be slide (standard or compatible variant)
• Mounting type must be through-hole
• Pitch must be 0.100" (2.54mm)
• Contact material must be beryllium copper with gold finish
• Operating temperature range must encompass -40°C to 85°C
• Product status must be active
• RoHS compliance must be maintained

The three C&K Electronics substitute parts (SD04H0B, SD04H0BD, SD04H1B) meet all mandatory substitution criteria. Variations exist in voltage rating (25VDC vs. 20VDC), actuator level (flush/recessed vs. raised), washability, mechanical life (2,000 cycles vs. unspecified), and electrical life (2,000 cycles vs. 1,000 cycles). These variations represent enhanced or alternative specifications within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

All three C&K Electronics substitute parts maintain active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment with the original 210-4LPSF specification.

SD04H0B and SD04H1B both feature tape seal construction and washability, providing enhanced environmental protection compared to the epoxy sealed terminals of the 210-4LPSF. SD04H0B maintains flush/recessed actuator level matching the original part, while SD04H1B provides a raised actuator level for applications requiring increased tactile feedback or accessibility.

SD04H0BD offers the lowest height above board (0.168" vs. 0.180"), making it suitable for space-constrained PCB layouts. This variant does not include washability or tape seal features.

All substitute parts provide 25VDC voltage rating, exceeding the 20VDC specification of the original part. All substitute parts specify 2,000 electrical life cycles, doubling the 1,000-cycle rating of the 210-4LPSF.

Frequently Asked Questions (FAQ)

Q: Can SD04H0B, SD04H0BD, and SD04H1B be used interchangeably with the 210-4LPSF?

A: Yes, within the constraints of your specific application. All three parts share identical circuit configuration (SPST), position count (4), current rating (100mA), actuator type (slide standard), mounting type (through-hole), and pitch (0.100"). The primary differences are actuator level (flush/recessed vs. raised for SD04H1B), height above board, and operational life ratings. Verify that your PCB layout accommodates the height variations and that your application does not require the specific washability or sealing characteristics of any particular variant.

Q: What is the significance of the 25VDC rating on the substitute parts versus the 20VDC rating on the 210-4LPSF?

A: The 25VDC rating on C&K parts represents a higher voltage capability. In applications operating at 20VDC or below, this higher rating provides additional design margin. The substitute parts are fully compatible with 20VDC operation.

Q: How do the electrical life ratings differ, and does this affect part selection?

A: The 210-4LPSF specifies 1,000 electrical life cycles, while all three C&K substitutes specify 2,000 cycles. This indicates the C&K parts are rated for twice the switching cycle endurance. For applications with high switching frequency or extended operational life requirements, the C&K substitutes offer enhanced durability.

Q: What is the difference between SD04H0B and SD04H0BD?

A: Both parts share identical electrical specifications and actuator level (flush/recessed). SD04H0B includes tape seal construction and washability features, while SD04H0BD does not. SD04H0BD has a lower height above board (0.168" vs. 0.178"), making it preferable for compact PCB designs. Select SD04H0B for applications requiring environmental protection through washability; select SD04H0BD for space-constrained layouts.

Q: Why would I select SD04H1B with its raised actuator level?

A: The raised actuator level on SD04H1B provides increased tactile feedback and easier manual operation compared to the flush/recessed level of the 210-4LPSF and other substitutes. This variant is suitable for applications where user accessibility or tactile confirmation of switch position is important.

Q: Are all parts packaged identically?

A: Yes, all parts are supplied in tube packaging, maintaining consistency with the original 210-4LPSF packaging specification.
