Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8041-05-011 is determined by strict equivalence across the following core electrical and mechanical parameters:

Critical Match Parameters:

• Coil voltage: 5VDC
• Contact form: SPDT (1 Form C)
• Contact rating: 250 mA minimum
• Coil current: 25 mA
• Coil type: Non Latching
• Termination style: PC Pin
• Mounting type: Through Hole
• Features: Diode
• Coil resistance: 200 Ohms

Acceptable Variation Ranges:

• Switching voltage: Must support at least 100VDC (higher ratings acceptable)
• Must operate voltage: 3.5 VDC to 3.8 VDC range acceptable
• Must release voltage: 0.5 VDC to 0.75 VDC range acceptable
• Operating temperature: Minimum -20°C and maximum 70°C or higher
• Operate/Release time: Within engineering tolerance for switching applications
• RoHS/REACH compliance: Equivalent or superior status

The two identified substitutes meet all critical parameters while demonstrating equivalent or enhanced specifications in switching voltage rating, operating voltage margins, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

DIP05-1C90-51D (Standex-Meder Electronics) is classified as a direct manufacturer substitute. This component is currently active in production and carries ROHS3 compliance certification. The switching voltage rating is elevated to 175V across both AC and DC specifications, providing increased margin for high-voltage applications. The operating temperature range extends to -20°C minimum with a 70°C maximum, making it suitable for standard industrial environments. This part is supplied in Tube packaging and represents the most direct drop-in replacement for the obsolete 8041-05-011.

V23100V4305C010 (TE Connectivity Potter & Brumfield Relays) is classified as a similar manufacturer substitute. This component maintains active production status with RoHS compliance. The switching voltage rating of 175VDC provides enhanced performance margin. The extended operating temperature range of -40°C to 85°C exceeds the original specification, supporting applications in wider thermal environments. The contact material is specified as Ruthenium, providing distinct contact metallurgy. This part is supplied in Tube packaging.

Both substitutes are available in new original stock quantities (852 Pcs and 671 Pcs respectively) and comply with REACH regulations. Selection between the two substitutes depends on specific application requirements regarding temperature extremes and contact material preferences.

Frequently Asked Questions (FAQ)

Q: Are DIP05-1C90-51D and V23100V4305C010 direct pin-for-pin replacements for 8041-05-011?

A: Both parts are direct substitutes with identical coil voltage (5VDC), contact form (SPDT), contact rating (250 mA), coil current (25 mA), termination style (PC Pin), and mounting type (Through Hole). Pinout configuration is equivalent, enabling direct PCB installation without layout modifications.

Q: What is the significance of the switching voltage difference (100V vs. 175V)?

A: The original 8041-05-011 has a maximum switching voltage of 100VAC/100VDC. The substitute parts are rated for 175V across AC and DC, or 175VDC only in the TE Connectivity variant. This higher rating provides additional safety margin in applications where switching voltage approaches the original specification limit.

Q: How do the operating temperature ranges compare?

A: The 8041-05-011 operates from -20°C to 85°C. The DIP05-1C90-51D operates from -20°C to 70°C, suitable for standard industrial temperature ranges. The V23100V4305C010 operates from -40°C to 85°C, extending the low-temperature capability for cryogenic or extreme environment applications.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both certifications restrict hazardous substances in electronics manufacturing. ROHS3 (RoHS 3) represents updated EU Directive 2011/65/EU with expanded substance restrictions. The DIP05-1C90-51D carries ROHS3 certification, representing compliance with the current regulatory framework.

Q: Are there differences in coil resistance or electrical drive requirements?

A: All three parts specify 200 Ohms coil resistance and 25 mA coil current, eliminating the need for circuit modifications to driver components or power supply specifications.

Q: What packaging considerations should be evaluated?

A: The original 8041-05-011 lacks specified packaging information. Both substitutes are supplied in Tube packaging, which is standard for through-hole relay components and supports both manual and automated assembly processes.

Q: Do the substitutes have identical operate and release time characteristics?

A: The DIP05-1C90-51D has a 0.7 ms operate time versus the original 1 ms specification. The V23100V4305C010 operates at 1.1 ms. Release times are 1.5 ms to 1.6 ms across all three parts. Applications with strict timing requirements should confirm compatibility with these specifications.
