Weidmüller 4058520000 General Purpose Relay SPDT 16A 115VAC - Equivalent & Substitute Parts

Part Overview

The Weidmüller 4058520000 is a general purpose relay with SPDT (Single Pole Double Throw) contact configuration, rated for 16A at 250VAC maximum switching voltage with a 115VAC coil. This through-hole mounted relay features non-latching operation and silver nickel contact material. The part is classified as obsolete, making identification of active equivalent models essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

The Weidmüller 8693890000 qualifies as a direct substitute for the 4058520000 based on the following critical parameters:

• Contact Configuration: Both parts feature SPDT (1 Form C) contact form
• Current Rating: Both rated for 16A continuous contact current
• Coil Voltage: Both operate on 115VAC supply
• Maximum Switching Voltage: Both rated 250VAC maximum
• Mounting and Termination: Both use through-hole mounting with PC pin termination
• Coil Type: Both are non-latching relays
• Contact Material: Both use silver nickel (AgNi) contacts
• Operating Temperature: Both function across -40°C to 70°C range
• Regulatory Compliance: Both are RoHS compliant and REACH unaffected

The 8693890000 represents an active product status alternative, making it suitable for new designs and ongoing procurement where the obsolete 4058520000 is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 8693890000 is the direct substitute for the obsolete 4058520000. Both parts maintain identical electrical specifications for coil voltage, contact rating, switching voltage, and operating temperature range. The 8693890000 is currently in active production status with full RoHS compliance and REACH unaffected certification, making it the appropriate choice for replacement applications.

The 8693890000 offers improved operational characteristics with faster release time (3 ms versus 45 ms) and faster operate time (7 ms versus 9 ms), along with sealed flux protection and documented coil parameters. These enhancements do not alter the fundamental substitution relationship but provide superior performance in equivalent circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 8693890000 directly replace the 4058520000 in existing circuits?

A: Yes. Both relays share identical contact configuration (SPDT), current rating (16A), coil voltage (115VAC), maximum switching voltage (250VAC), mounting type (through-hole), and termination style (PC pin). The electrical and mechanical interfaces are equivalent.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete versus active) and operational timing. The 8693890000 operates faster (7 ms operate time, 3 ms release time) compared to the 4058520000 (9 ms operate time, 45 ms release time). The 8693890000 includes sealed flux protection and documented coil specifications (6.6 mA, 8.1 kOhms).

Q: Are there packaging differences?

A: The 4058520000 packaging is listed as unspecified, while the 8693890000 is supplied in bulk packaging. Both use identical PC pin through-hole termination suitable for PCB mounting.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the 4058520000 and 8693890000 are RoHS compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Which part should be specified for new designs?

A: The 8693890000 should be specified for new designs due to its active product status, improved operational characteristics, and ongoing manufacturer support.
