DSP1-DC9V General Purpose Relay Equivalent & Substitute Parts

Part Overview

The DSP1-DC9V is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPST contact configuration with 9VDC coil voltage and 5A contact rating. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The DSP1-DC9V-F serves as the direct manufacturer equivalent, offering identical electrical and mechanical specifications with active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSP1-DC9V is determined by strict equivalence across the following critical parameters:

Coil voltage specification (9VDC), contact configuration (DPST-NO/NC), current rating (5A), switching voltage limits (250VAC, 125VDC maximum), and mechanical mounting characteristics (through hole, PC pin termination). The substitute part must maintain identical coil resistance (270 Ohms), coil current draw (33.3 mA), and temporal response characteristics (10 ms operate time, 5 ms release time). Operating temperature range (-40°C to 65°C) and contact material composition (Silver Tin Oxide) must remain consistent. The DSP1-DC9V-F meets all these criteria as a direct manufacturer equivalent within the DSP series.

Parameter Comparison

Engineering Selection Recommendations

The DSP1-DC9V-F is the direct substitute for the obsolete DSP1-DC9V. Both components share identical electrical specifications, mechanical form factor, and regulatory certifications (cURus, VDE). The DSP1-DC9V-F maintains active product status, ensuring continued availability and supply chain reliability. Both parts comply with REACH regulations and carry EAR99 classification. The DSP1-DC9V-F is available in bulk packaging, whereas the original part number carries standard packaging designation. Selection of the DSP1-DC9V-F eliminates obsolescence risk while preserving complete functional and physical compatibility with existing circuit designs and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can DSP1-DC9V-F directly replace DSP1-DC9V in existing applications?

A: Yes. The DSP1-DC9V-F is electrically and mechanically identical to the DSP1-DC9V across all specified parameters, including coil voltage, contact configuration, current rating, switching characteristics, and physical mounting. Direct substitution is valid without circuit modification.

Q: What is the primary difference between DSP1-DC9V and DSP1-DC9V-F?

A: Product status and packaging. The DSP1-DC9V is obsolete with standard packaging, while the DSP1-DC9V-F is active with bulk packaging availability. All electrical and mechanical specifications remain identical.

Q: Are there regulatory or compliance differences between these parts?

A: No. Both parts carry identical regulatory approvals (cURus, VDE), REACH compliance status, and ECCN/HTSUS classifications. Compliance requirements are fully satisfied by either part number.

Q: What packaging options are available?

A: The DSP1-DC9V-F is supplied in bulk packaging. The original DSP1-DC9V carries standard packaging designation. Packaging selection depends on procurement volume and inventory management requirements.

Q: Is the DSP1-DC9V-F suitable for new design implementations?

A: Yes. The active product status of DSP1-DC9V-F ensures long-term availability and supply chain continuity, making it the appropriate choice for new designs requiring a 9VDC DPST general purpose relay with 5A contact rating.
