Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by strict equivalency of provided electrical and mechanical parameters. The following criteria are maintained in the selection process: circuit type (SPST), number of positions, actuator type and level, mounting style, termination method, pitch, voltage and current ratings, contact material and finish, body material, switch life cycles, physical dimensions, compliance requirements, and all provided certifications. Only parts matching these listed parameters are considered substitutes.

Parameter Comparison

Engineering Selection Recommendations

The DP02T is classified as obsolete, requiring transition to an active DIP switch model for continuity in design and production. The substitute part KAP1102R from E-Switch is active and maintains compliance with ROHS3 and relevant MSL and REACH standards. Both parts conform to the specified ECCN and HTSUS codes.

Frequently Asked Questions (FAQ)

Q: What defines the compatibility between DP02T and KAP1102R for substitution?
A: Compatibility is defined strictly by identical electrical and mechanical parameters: SPST circuit, 2 positions, 24VDC rating, piano actuator type and level, through-hole right-angle mounting, PC pin termination, 0.100" (2.54mm) pitch, contact material and finish, body dimensions, and regulatory compliance.

Q: Are the mounting and pin configurations interchangeable between DP02T and KAP1102R?
A: Both switches feature through-hole, right-angle mounting and PC pin termination with identical pitch and board height, supporting direct interchangeability in PCB layouts.

Q: Does RoHS and REACH compliance differ between the DP02T and KAP1102R?
A: Both components are ROHS3 Compliant and REACH Unaffected, maintaining full compliance equivalence.

Q: What package type is provided for the substitute part?
A: KAP1102R is supplied in standard packaging suitable for through-hole DIP switch installation, matching the form factor of DP02T.

Q: Is there a variation in the actuator or number of positions between DP02T and KAP1102R?
A: Both parts are 2-position piano DIP switches with flush, recessed actuators, aligning exactly on these parameters.

Q: Are there differences in switch life cycles or electrical performance between the models?
A: The substitute part KAP1102R specifies identical electrical life but a lower mechanical life and current rating when compared to the DP02T. Both conform to the 24VDC voltage rating.

Q: Are moisture sensitivity and environmental controls maintained in the substitute part?
A: Both main and substitute parts are classified as MSL 1 (Unlimited), ensuring consistent handling requirements.
