RE030012 General Purpose Relay SPST 12VDC Equivalent & Substitute Parts

Part Overview

The RE030012 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays, configured as a Single Pole Single Throw (SPST-NO) relay with a 12VDC coil and 6A contact rating. This through-hole mounted relay features a sealed design with Silver Cadmium Oxide contacts and operates across a temperature range of -40°C to 70°C. The RE030012 is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RE030012 is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Critical Parameters for Substitution:

• Coil voltage (12VDC)
• Contact form (SPST-NO)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Coil type (Non Latching)
• Seal rating (Sealed - Fully)

Secondary Parameters Affecting Compatibility:

• Contact rating current (minimum 6A required)
• Switching voltage capability
• Operating temperature range
• Coil current and resistance characteristics

The RE034012 is a direct equivalent from the same manufacturer with identical electrical specifications and contact form. The Panasonic DSP1A-DC12V and DSP1A-DC12V-R are similar substitutes with higher contact current ratings (8A) and different contact material composition, suitable for applications where the 6A rating is not a limiting factor.

Parameter Comparison

Engineering Selection Recommendations

RE034012 (Direct Equivalent)

The RE034012 is the primary substitute for the RE030012. Both relays share identical electrical specifications, contact form, and mounting characteristics. The RE034012 is currently in active production status with 2338 units in stock, compared to the obsolete RE030012. The RE034012 is ROHS3 compliant and carries REACH unaffected status, meeting current regulatory requirements. The contact material differs (Silver Nickel versus Silver Cadmium Oxide), but both materials are suitable for general purpose switching applications. The RE034012 is supplied in tube packaging.

DSP1A-DC12V and DSP1A-DC12V-R (Similar Substitutes)

The Panasonic DSP1A-DC12V and DSP1A-DC12V-R relays are suitable substitutes where the application does not require the full 400VAC switching voltage capability of the RE030012. These relays feature an 8A contact rating, exceeding the 6A requirement of the RE030012. Both are active products with ROHS3 compliance and REACH unaffected status. The DSP1A-DC12V-R variant includes reverse coil polarity capability. The Panasonic relays operate at a maximum temperature of 60°C, which is 10°C lower than the RE030012. Coil current is higher at 25 mA compared to 16.7 mA for the RE030012. Both Panasonic relays are supplied in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the RE034012 be used as a direct replacement for the RE030012?

A: Yes. The RE034012 is a direct equivalent with identical coil voltage (12VDC), contact form (SPST-NO), contact rating (6A), mounting type (through hole), and termination style (PC pin). Both relays are fully sealed with non-latching coil types. The primary difference is product status (RE034012 is active) and contact material composition (Silver Nickel versus Silver Cadmium Oxide). The RE034012 is ROHS3 compliant and currently in production.

Q: What are the differences between the TE Connectivity RE034012 and the Panasonic DSP1A-DC12V?

A: The RE034012 and DSP1A-DC12V differ in several parameters. The RE034012 maintains the 6A contact rating and 400VAC switching voltage of the original RE030012. The DSP1A-DC12V provides an 8A contact rating but is limited to 250VAC switching voltage. The DSP1A-DC12V requires higher coil current (25 mA versus 16.7 mA) and has lower coil resistance (480 Ohms versus 720 Ohms). The DSP1A-DC12V operates to a maximum temperature of 60°C, compared to 70°C for the RE034012. Both are fully sealed, non-latching relays with through-hole PC pin termination.

Q: Are the Panasonic DSP1A-DC12V and DSP1A-DC12V-R interchangeable?

A: The DSP1A-DC12V and DSP1A-DC12V-R are electrically identical except for coil polarity. The DSP1A-DC12V-R includes reverse coil polarity capability as a distinguishing feature. Both relays share identical contact ratings (8A), switching voltage (250VAC, 125VDC), coil current (25 mA), and operating temperature range (-40°C to 60°C). Selection between these variants depends on circuit polarity requirements.

Q: What is the impact of different contact materials on relay performance?

A: The RE030012 uses Silver Cadmium Oxide (AgCdO) contacts, the RE034012 uses Silver Nickel (AgNi), and the Panasonic relays use Silver Tin Oxide (AgSnO). All three contact materials are suitable for general purpose switching applications. Contact material selection affects arc erosion characteristics, contact resistance, and switching performance under specific load conditions. For general purpose applications within the specified current and voltage ratings, all three materials provide equivalent performance.

Q: Can the DSP1A-DC12V be used in applications requiring 400VAC switching capability?

A: No. The DSP1A-DC12V is rated for a maximum switching voltage of 250VAC and 125VDC. Applications requiring 400VAC switching capability must use the RE034012 or RE030012, both rated for 400VAC maximum switching voltage. Exceeding the switching voltage rating of a relay can result in contact degradation and failure.

Q: What are the packaging differences among these relays?

A: The RE030012 packaging is not specified. The RE034012 is supplied in tube packaging. The Panasonic DSP1A-DC12V and DSP1A-DC12V-R are supplied in bulk packaging. Packaging selection affects handling, storage, and integration into manufacturing processes. Tube packaging provides individual component protection, while bulk packaging is suitable for high-volume automated assembly.

Q: Are all substitute relays RoHS compliant?

A: The RE034012 is ROHS3 compliant. The DSP1A-DC12V is ROHS3 compliant. The DSP1A-DC12V-R is RoHS compliant. All three substitute relays meet RoHS requirements. The RE030012 product status does not specify RoHS compliance. Current regulatory requirements favor ROHS3 compliant components for new designs.
