Key Parameters

Substitute Part Grouping Explanation

Substitution grouping is determined by comparison across the following explicitly provided parameters: category (Configurable Switch Components), circuit type, contact rating at voltage, termination style, required assembly (Switch Body), compatible series, compliance status (RoHS, REACH), export classification (ECCN), harmonized tariff schedule (HTSUS), and packaging format. Substitutes are included only if all relevant parameters match or are indicated accordingly within their respective product families for this category.

Parameter Comparison

Engineering Selection Recommendations

Component selection is based solely on the parameters provided, including product status, regulatory compliance (RoHS3, REACH), and export classification (ECCN, HTSUS). LB-T60 maintains ROHS3 and REACH compliance, carries the same ECCN and HTSUS codes, and is listed as active inventory. It meets the environmental and regulatory requirements specified for this product category.

Frequently Asked Questions (FAQ)

Q: What substitution criteria must be met for contact blocks in configurable switch components?
A: Substitution criteria are determined by matching product category, circuit type, contact rating at voltage, termination style, required assembly, compatible series, compliance status, and regulatory codes.

Q: Are contact blocks interchangeable between different series or manufacturers?
A: Interchangeability depends strictly on compatible series and mechanical parameters specified in the component’s documentation.

Q: Does packaging type impact the substitution process?
A: Both A02503 and LB-T60 are packaged in bulk, aligning with the specified packaging parameter.

Q: How is regulatory compliance ensured for substitute parts?
A: Both parts are ROHS3 compliant and REACH unaffected, with matching ECCN and HTSUS classifications as specified.

Q: What does “Requires: Switch Body” indicate for substitute selection?
A: Substitute contact blocks must be assembled with an appropriate switch body, as specified for the product category.
