Substitute Part Grouping Explanation

Substitution is determined using specific electrical and mechanical parameters. Substitutes must match or exceed:

Mating dimensions (2.50mm ID, 5.50/6.40mm OD)
Number of conductors/contacts
Internal switch configuration
Mounting type and termination method
Voltage and current rating
Material flammability rating
Operating temperature
Environmental compliance (RoHS, MSL)

Only parts conforming exactly to these explicit parameters are considered as equivalents or substitutes in this reference.

Engineering Selection Recommendations

Selection should be based on component status (active or obsolete) and environmental compliance (RoHS, MSL level). KLDX-0202-BHT is obsolete, while KLDX-0202-BHT-1 and PJ-002B are active and ROHS3 compliant. All listed parts are classified with MSL 1 (unlimited), which is suitable for standard storage and assembly conditions.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting KLDX-0202-BHT barrel connectors?
A1: The primary parameters are mating diameter, current and voltage rating, mounting type, number of contacts, internal switch configuration, material flammability, and compliance status.

Q2: Are KLDX-0202-BHT-1 and PJ-002B functionally compatible with KLDX-0202-BHT?
A2: Both substitute parts meet the key electrical and mechanical parameters, including diameter, voltage, and switch configuration.

Q3: Will there be differences in environmental compliance?
A3: All parts listed are RoHS3 compliant and designated as MSL 1 (unlimited), aligning with standard requirements.

Q4: Why is it necessary to find a substitute for KLDX-0202-BHT?
A4: KLDX-0202-BHT is classified as obsolete, which makes it unsuitable for new designs or ongoing production without assured supply.

Q5: Does the packaging type affect substitution?
A5: Packaging should be chosen according to assembly process needs; KLDX-0202-BHT-1 offers Tape & Reel, while PJ-002B is supplied in bags.

Q6: Are there differences in housing material among substitutes?
A6: KLDX-0202-BHT and PJ-002B use Polybutylene Terephthalate (PBT), and KLDX-0202-BHT-1 uses thermoplastic.

Q7: Is current rating always identical among substitutes?
A7: KLDX-0202-BHT and KLDX-0202-BHT-1 are rated at 3.5A, while PJ-002B is rated at 2.5A, as specified.
