Key Parameters

Substitute Part Grouping Explanation

Substitute components for the 9802-05-10 are identified based on electrical equivalence across critical parameters: coil voltage specification (5VDC), coil current draw (33.3 mA), contact rating (250 mA), contact form (SPST-NO), switching voltage maximum (100VAC/100VDC), operating temperature range (-20°C to 85°C), mounting technology (surface mount), and compliance certifications (RoHS, REACH, ECCN). Mechanical differences such as termination style (axial versus gull wing) and packaging format do not affect electrical substitution eligibility but must be considered during PCB layout and assembly planning.

Parameter Comparison

Engineering Selection Recommendations

The Coto Technology 9814-05-00 is the qualified substitute for the obsolete 9802-05-10. Both components maintain identical electrical characteristics, functional performance, and compliance certification status (RoHS3 and REACH Unaffected). The primary distinction is product status: the 9814-05-00 is active and currently manufactured, with demonstrated inventory availability (2200 pcs), ensuring long-term supply chain continuity.

The mechanical difference in termination style (gull wing on substitute versus axial on main part) requires footprint verification and PCB design adjustment during component placement. Both parts share equivalent moisture sensitivity classification (MSL 2) and ECCN/HTSUS coding, maintaining regulatory consistency across procurement and logistics operations.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for the 9814-05-00 to substitute for the 9802-05-10? A: The following parameters are identical: 5VDC coil voltage, 33.3 mA coil current, 250 mA contact rating, SPST-NO contact form, 100VAC/100VDC maximum switching voltage, 3.8 VDC must-operate voltage, 0.4 VDC must-release voltage, 0.25 ms operate time, 0.05 ms release time, -20°C to 85°C operating temperature, and 150 Ohms coil resistance. Full electrical equivalence is confirmed.

Q: Does the termination style difference (axial to gull wing) affect circuit performance? A: No. Termination style is a mechanical specification affecting PCB footprint and assembly process only. Electrical performance, switching characteristics, and contact ratings remain unchanged. PCB layout must be modified to accommodate the gull wing lead geometry.

Q: Are there compliance considerations for this substitution? A: Both components are ROHS-compliant (the substitute meets ROHS3), REACH Unaffected, and classified under identical ECCN (EAR99) and HTSUS codes. Regulatory status is maintained across the substitution.

Q: What is the difference in packaging between these parts? A: The 9802-05-10 packaging format is listed as dash (-), while the 9814-05-00 is supplied in Tube packaging. This affects receiving, handling, and assembly procedures but does not alter electrical compatibility.

Q: Why is the 9814-05-00 recommended over the 9802-05-10? A: The 9802-05-10 is classified as obsolete with no active manufacturing. The 9814-05-00 is the active equivalent from the same manufacturer and series (9800), with current production status and confirmed inventory availability ensuring sustainable component sourcing for production and field service needs.
