Substitute Part Grouping Explanation

Substitution of the DSP1-DC9V-R with the DSP1-DC9V-F is based on complete electrical and mechanical parameter equivalence. Both components share identical specifications across all critical substitution criteria:

Coil voltage (9VDC), contact configuration (DPST-NO/NC), current rating (5A), switching voltage limits (250VAC, 125VDC), maximum load capacity (1500VA, 625W), coil current (33.3 mA), coil resistance (270 Ohms), mounting type (Through Hole), termination style (PC Pin), operating temperature range (-40°C ~ 65°C), contact material (Silver Tin Oxide), seal rating (Sealed - Fully), timing characteristics (10 ms operate, 5 ms release), and regulatory approvals (cURus, VDE).

The primary distinction is product status: DSP1-DC9V-R is obsolete while DSP1-DC9V-F maintains active status, and packaging differs (DSP1-DC9V-F supplied in Bulk).

Parameter Comparison

Engineering Selection Recommendations

The DSP1-DC9V-F is the direct functional equivalent for DSP1-DC9V-R applications. Selection of DSP1-DC9V-F is supported by:

Active product status ensuring continued availability and supply chain reliability. ROHS3 compliance of DSP1-DC9V-F provides regulatory advantage for new designs and systems subject to environmental directives. Both components maintain identical cURus and VDE certifications, confirming equivalent safety and performance standards. Electrical and mechanical parameters are fully interchangeable, with no circuit or mechanical redesign required for substitution.
