Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS2E-S-DC12V-R are qualified based on the following critical parameters:

• Coil Voltage: 12VDC (exact match required)
• Contact Form: DPDT (2 Form C) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)
• Coil Resistance: 720 Ohms (exact match required)
• Coil Current: 16.7 mA (exact match required)

Substitute parts may vary in contact rating (current capacity), operating temperature range, switching voltage specifications, and timing characteristics, provided the core electrical and mechanical parameters remain compatible with the original application requirements.

Engineering Selection Recommendations

C93418 (TE Connectivity Potter & Brumfield Relays)

The C93418 is a direct functional equivalent for the DS2E-S-DC12V-R in applications requiring 2A contact rating. Both parts share identical coil voltage, contact form, coil current, and coil resistance specifications. The C93418 operates across a wider temperature range (-55°C ~ 85°C) and features faster switching times (5 ms operate, 3 ms release). This part is RoHS3 compliant and maintains REACH unaffected status. The C93418 is suitable for replacement in existing designs where the original DS2E-S-DC12V-R specifications are met.

V23105A5303A201 (TE Connectivity Potter & Brumfield Relays)

The V23105A5303A201 is a higher-capacity substitute with 3A contact rating compared to the 2A rating of the DS2E-S-DC12V-R. All core electrical parameters (coil voltage, contact form, coil current, coil resistance) are identical. This part features improved release voltage performance (0.6 VDC vs. 1.2 VDC) and faster switching times (6 ms operate, 4 ms release). The V23105A5303A201 is RoHS compliant and operates across -40°C ~ 85°C. This part is suitable for applications where higher contact current capacity is beneficial or required.

Both substitute parts are classified as obsolete and maintain equivalent regulatory compliance to the original DS2E-S-DC12V-R.

Frequently Asked Questions (FAQ)

Q: Can the C93418 directly replace the DS2E-S-DC12V-R in existing PCB designs?

A: Yes. The C93418 shares identical mounting type (through hole), termination style (PC pin), coil voltage (12VDC), contact form (DPDT), coil current (16.7 mA), and coil resistance (720 Ohms). Physical pin compatibility must be verified against the specific PCB layout, as packaging differences may exist.

Q: What is the primary difference between the C93418 and V23105A5303A201?

A: The primary difference is contact rating. The C93418 maintains the 2A rating of the original DS2E-S-DC12V-R, while the V23105A5303A201 provides 3A contact rating. Both are functionally equivalent in terms of coil specifications and switching voltage.

Q: Are there packaging differences between these substitute parts?

A: Yes. The DS2E-S-DC12V-R is packaged in standard through-hole format. The C93418 is supplied in tube packaging, while the V23105A5303A201 is supplied in box packaging. Verify packaging compatibility with assembly and storage requirements.

Q: Can the V23105A5303A201 be used in applications designed for 2A contact rating?

A: Yes. The V23105A5303A201 provides 3A contact rating, which exceeds the 2A requirement of the original DS2E-S-DC12V-R. Higher contact rating does not create incompatibility in applications designed for lower current switching.

Q: What compliance certifications apply to these substitute parts?

A: The DS2E-S-DC12V-R and C93418 are both REACH unaffected. The C93418 is RoHS3 compliant. The V23105A5303A201 is RoHS compliant. All three parts carry EAR99 ECCN classification and 8536.41.0020 HTSUS code.

Q: Do the substitute parts have different operating temperature ranges?

A: Yes. The DS2E-S-DC12V-R operates -40°C ~ 70°C. The C93418 operates -55°C ~ 85°C (wider range). The V23105A5303A201 operates -40°C ~ 85°C (extended upper limit). Verify application temperature requirements before selection.
