Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7102-05-1100 is based on electrical and mechanical parameter equivalence within the following criteria:

Critical Matching Parameters:

• Coil voltage: 5VDC
• Contact form: DPST-NO (2 Form A)
• Contact current rating: 500 mA
• Switching voltage: 200VAC, 200VDC maximum
• Mounting type: Through hole
• Termination style: PC pin
• Operating temperature range: -20°C to 85°C
• Coil type: Non latching

The Coto Technology 2332-05-000 satisfies all critical electrical and mechanical parameters required for direct substitution. This part belongs to the active 2300 series and represents the current production equivalent to the obsolete 7102 series.

Parameter Comparison

Engineering Selection Recommendations

The Coto Technology 2332-05-000 is the direct substitute for the obsolete 7102-05-1100 based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters match exactly, including coil voltage, contact form, current rating, and switching voltage specifications. The substitute exhibits lower coil current (28.6 mA versus 33.3 mA) and higher coil resistance (175 Ohms versus 150 Ohms), resulting in reduced power consumption during operation.

Mechanical Compatibility: Both parts feature identical through-hole mounting and PC pin termination, ensuring direct PCB compatibility without layout modifications.

Performance Characteristics: The 2332-05-000 demonstrates improved switching performance with faster operate time (0.5 ms versus 1 ms), while release time remains within acceptable tolerance (0.15 ms versus 0.1 ms).

Compliance and Status: The substitute part is ROHS3 compliant and maintains active production status, ensuring long-term availability and supply chain continuity. Both parts carry REACH unaffected status and EAR99 ECCN classification.

Packaging Consideration: The substitute is supplied in tray packaging, whereas the main part packaging is not specified. This represents a standard production format change without functional impact.

Seal Enhancement: The 2332-05-000 includes hermetic sealing, providing superior environmental protection compared to the unspecified seal rating of the 7102-05-1100.

Frequently Asked Questions (FAQ)

Q: Can the 2332-05-000 directly replace the 7102-05-1100 in existing designs?

A: Yes. The 2332-05-000 meets all critical electrical and mechanical parameters required for direct substitution. Coil voltage, contact configuration, current rating, switching voltage, mounting type, and termination style are identical. The part operates within the same temperature range and maintains equivalent voltage thresholds for operation and release.

Q: What are the differences in coil characteristics between these parts?

A: The 2332-05-000 exhibits lower coil current (28.6 mA versus 33.3 mA) and higher coil resistance (175 Ohms versus 150 Ohms). These differences result in reduced power consumption and heat generation during operation. Both parts operate at 5VDC and maintain equivalent must-operate and must-release voltage thresholds.

Q: How do the switching times compare?

A: The 2332-05-000 operates faster with a 0.5 ms operate time compared to 1 ms for the 7102-05-1100. Release time is slightly longer at 0.15 ms versus 0.1 ms. These timing differences remain within typical application tolerances for reed relay switching applications.

Q: What is the significance of the hermetic sealing in the 2332-05-000?

A: Hermetic sealing provides enhanced protection against moisture ingress and environmental contamination. This feature improves long-term reliability in applications exposed to humidity or corrosive environments. The 7102-05-1100 seal rating is not specified, whereas the 2332-05-000 explicitly includes hermetic sealing.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant. The 7102-05-1100 carries RoHS compliance status, while the 2332-05-000 is ROHS3 compliant, representing a more current regulatory standard. Both parts are REACH unaffected and carry EAR99 ECCN classification.

Q: Does packaging format affect component selection?

A: Packaging format does not affect electrical or mechanical compatibility. The 2332-05-000 is supplied in tray packaging, a standard production format. Selection should be based on procurement and assembly process requirements rather than functional performance.

Q: Why is the 7102-05-1100 classified as obsolete?

A: The 7102 series has been superseded by the active 2300 series, of which the 2332-05-000 is a current production member. The 2332-05-000 provides equivalent functionality with improved performance characteristics and enhanced sealing. Obsolete classification indicates that the 7102-05-1100 is no longer in active production, making the 2332-05-000 the recommended alternative for new designs and ongoing production.
