- Covers housing pin-count ranges (2P–20P), single-row vs. dual-row configurations, DIP vs. SMT mounting orientation (90°/180°), free-hanging vs. in-line vs. ultra-thin housing types, and terminal selection criteria for 1.25mm pitch connector families such as KR1250, KR1251, KR1252, and KR1253.
- “JST 1.25 vs. Molex MX1.25 vs. HIROSE DF13: What’s the Difference?”
- Compares cross-reference compatibility, housing configurations, and mounting options across the KR1250 series (Molex MX1.25 equivalent) and KR1256 series (HIROSE DF13 1.25mm equivalent) to help buyers identify the correct domestic replacement part.
- “Wire-to-Board Connectors: Types, Working Principles, and Selection Guide”
- General reference for choosing between wire-to-board series (KR1000, KR1259, KR1250, KR1256) based on pitch, current rating, and application environment.
- “Domestic Replacement Connectors: Types, Working Principles, and Selection Guide”
- Explains how KONNRA’s cross-referenced connector series (JST, HIROSE, Molex, YEONHO) support imported-part replacement while maintaining stable performance and controlled cost, using KR2017 as a reference case for material technology improvement in coastal and cold-area environments.
