Key Parameters

Substitute Part Grouping Explanation

The 9852-05-00 qualifies as a direct electrical equivalent to the 9852-05-10 based on the following critical parameters:

• Coil Specifications: Identical coil voltage (5VDC), coil current (45.5 mA), and coil resistance (110 Ohms)
• Contact Specifications: Matching SPDT contact form, 100mA contact rating, and 30VAC/30VDC switching voltage maximum
• Operating Characteristics: Identical must-operate voltage (3.8 VDC), must-release voltage (0.4 VDC), operate time (1 ms), and release time (1 ms)
• Environmental Specifications: Matching operating temperature range (-20°C to 85°C), MSL rating (2), and magnetic shield feature
• Regulatory Compliance: Both parts comply with RoHS, REACH Unaffected status, and ECCN EAR99 classification

The primary difference is termination style (axial versus gull wing) and product status (obsolete versus active), with the 9852-05-00 offering superior supply availability.

Parameter Comparison

Engineering Selection Recommendations

The 9852-05-00 is the qualified substitute for the obsolete 9852-05-10. Both parts maintain identical electrical and mechanical specifications across all critical relay parameters. The primary selection criteria are:

• Product Status: The 9852-05-00 is actively manufactured with significantly higher inventory availability (2444 units versus 793 units), making it the preferred choice for new designs and ongoing production requirements.
• RoHS Compliance: The 9852-05-00 carries ROHS3 Compliant designation, whereas the main part lists RoHS Compliant status, providing enhanced compliance assurance for modern procurement standards.
• Packaging and Termination: The 9852-05-00 is supplied in standard tube packaging with gull wing termination, suitable for automated assembly processes. The 9852-05-10 uses axial termination and unmarked packaging, relevant only for specific legacy board designs.
• Regulatory Certification: Both parts maintain identical REACH Unaffected and ECCN EAR99 classifications, confirming equivalent regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the 9852-05-00 directly replace the 9852-05-10 in existing circuits?

A: Yes. The 9852-05-00 provides electrical equivalence with identical coil voltage, coil current, contact ratings, switching characteristics, and operating temperature range. Circuit-level compatibility is maintained without design modifications.

Q: What is the significance of the termination style difference (axial versus gull wing)?

A: Termination style affects assembly compatibility. Axial termination is used in through-hole or wire-lead applications, while gull wing termination supports surface-mount automated assembly. Circuit function remains identical; the selection depends on your board assembly process and routing design.

Q: Does the ROHS3 Compliant status of the 9852-05-00 indicate differences from the RoHS Compliant 9852-05-10?

A: No functional difference exists. ROHS3 Compliant is the current designation standard and indicates the part meets modern RoHS requirements. Both parts satisfy equivalent environmental and hazardous substance restrictions for their respective manufacturing periods.

Q: Which part should be selected for new product designs?

A: The 9852-05-00 is specified for new designs because it is actively manufactured with superior availability and current compliance certifications. The 9852-05-10 is obsolete and should only be used for legacy design maintenance or field replacement of existing units.

Q: Are there any differences in magnetic shielding or RF performance between the two parts?

A: Both parts include magnetic shield features with identical specifications. No RF performance differences are documented in the provided parameters.

Q: What is the impact of MSL 2 rating on storage and handling?

A: MSL 2 (1 Year) classification applies identically to both parts, specifying that components remain qualified for assembly for one year from manufacturing date when stored in controlled moisture conditions. No differential handling requirements apply.
