Key Parameters

Substitute Part Grouping Explanation

The 9007-12-00 functions as a direct electrical and mechanical equivalent for the obsolete 9007-12-50, satisfying substitution criteria based on the following parameters: identical coil voltage (12VDC), contact form (SPST-NO), contact rating (500 mA), switching voltage rating (200VAC/200VDC max), mounting type (through hole), termination style (PC pin), must operate voltage (9 VDC), must release voltage (1 VDC), operate time (0.5 ms), release time (0.2 ms), operating temperature range (-20°C ~ 85°C), RoHS compliance status, MSL rating, REACH status, and ECCN classification. Both components are manufactured by Coto Technology within the same product series. The substitute part maintains active product status with established supply chain availability, whereas the original part number is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The 9007-12-00 is the direct replacement for the obsolete 9007-12-50. Both components maintain RoHS compliance with ROHS3 certification on the substitute part, representing an advancement in regulatory status. Both are REACH Unaffected and classified as EAR99 under export control regulations. The electrical and mechanical characteristics remain equivalent, with identical switching behavior, operating temperature range, and performance timing specifications. The substitute part carries active product status, ensuring long-term availability and supply chain continuity. Primary design consideration involves coil current differential: the 9007-12-00 draws 12 mA compared to 6 mA for the 9007-12-50, corresponding to coil resistance values of 1 kOhm and 2 kOhm respectively. Power supply and drive circuit design must account for this increased coil current requirement when implementing the substitute component.

Frequently Asked Questions (FAQ)

Q: Are the 9007-12-50 and 9007-12-00 electrically interchangeable? A: Yes. Both components share identical coil voltage (12VDC), contact form (SPST-NO), contact rating (500 mA), switching voltage ratings (200VAC/200VDC max), operate time (0.5 ms), and release time (0.2 ms). They function identically in switching applications.

Q: What is the primary difference between these two relays? A: The coil current and coil resistance differ. The 9007-12-50 operates at 6 mA with 2 kOhm coil resistance, while the 9007-12-00 operates at 12 mA with 1 kOhm coil resistance. Drive circuit design must accommodate the higher coil current requirement of the substitute.

Q: Can I use 9007-12-00 in place of 9007-12-50 without circuit modification? A: Mechanical substitution is direct due to identical mounting type and termination style. However, the drive circuit must be evaluated to ensure the power supply can deliver the increased 12 mA coil current (versus 6 mA) without exceeding specified voltage tolerance limits.

Q: How do the regulatory and compliance statuses compare? A: Both components are RoHS compliant (the substitute carries ROHS3 certification), REACH Unaffected, and classified as EAR99 for export control. The substitute represents current regulatory alignment.

Q: What packaging differences exist between these parts? A: The 9007-12-50 is supplied with no specified packaging designation, while the 9007-12-00 is supplied in tube packaging. Both maintain through-hole PC pin termination for identical PCB integration.
