Key Parameters

Substitute Part Grouping Explanation

The DSP1-L2-DC5V-F qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following critical parameters:

• Coil voltage specification (5VDC)
• Contact form configuration (DPST-NO/NC)
• Current rating (5 A)
• Maximum switching voltage (250VAC, 125VDC)
• Coil current draw (60 mA)
• Coil type (Latching, Dual Coil)
• Mounting type (Through Hole)
• Operating temperature range (-40°C ~ 65°C)
• Coil resistance (83.3 Ohms)

The substitute part maintains all electrical and mechanical specifications of the original part while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The DSP1-L2-DC5V-F is the appropriate substitute for the obsolete DSP1-L2-DC5V. Both parts are manufactured by Panasonic Electric Works and share identical electrical and mechanical specifications, ensuring functional equivalence in circuit applications.

The substitute part offers two significant advantages over the main part:

1. Active product status with confirmed inventory availability (6400 pcs in stock)
2. ROHS3 compliance, meeting current environmental and regulatory requirements

For applications requiring RoHS compliance or long-term supply chain continuity, the DSP1-L2-DC5V-F is the recommended selection. Both parts carry identical approval certifications (cURus, VDE) and maintain the same operating characteristics across the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can DSP1-L2-DC5V-F be used as a direct replacement for DSP1-L2-DC5V?

A: Yes. Both parts are electrically and mechanically identical, with matching coil voltage (5VDC), contact configuration (DPST-NO/NC), current rating (5A), and all timing specifications. The substitute part is a direct functional equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance. DSP1-L2-DC5V is obsolete and RoHS non-compliant, while DSP1-L2-DC5V-F is active and ROHS3 compliant. Packaging differs (bulk for the substitute), but electrical performance is identical.

Q: Are there any compatibility concerns when switching from DSP1-L2-DC5V to DSP1-L2-DC5V-F?

A: No compatibility concerns exist. Both parts maintain identical pin configurations, coil resistance (83.3 Ohms), and switching characteristics. PCB layouts and circuit designs require no modification.

Q: Which part should be selected for new designs?

A: DSP1-L2-DC5V-F should be selected for new designs due to active product status, ROHS3 compliance, and confirmed supply availability.

Q: Are both parts approved by the same certification agencies?

A: Yes. Both parts carry identical approval certifications from cURus and VDE, meeting the same safety and performance standards.
