PSP700JB-12R Equivalent & Substitute Parts

Part Overview

The PSP700JB-12R is a 12 Ohm, 7W through-hole axial wirewound resistor manufactured by YAGEO. This component is designed for applications requiring high power dissipation with flame-proof and moisture-resistant characteristics. The part maintains Active product status with 675 units currently in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same resistance value, tolerance, power rating, and package configuration.

Substitute Part Grouping Explanation

Substitute parts for the PSP700JB-12R are qualified based on the following criteria:

• Resistance value: 12 Ohms
• Tolerance: ±5%
• Power rating: 7W
• Composition: Wirewound
• Package configuration: Axial or Axial with radial formed leads
• Operating temperature range: -55°C ~ 350°C minimum
• RoHS3 compliance
• Flame-proof and safety-rated construction

The SBCHE612RJ from TE Connectivity Passive Product meets all substitution criteria with identical electrical specifications and compatible mechanical packaging. Both parts support the same thermal operating window and regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both PSP700JB-12R and SBCHE612RJ are Active status components with ROHS3 compliance and EAR99 ECCN classification. Selection between these parts should be based on:

• PCB layout constraints: The SBCHE612RJ offers radial formed lead options in addition to standard axial configuration, providing flexibility for space-constrained applications
• Lead form requirements: Standard axial configuration is available from both manufacturers; radial formed leads are exclusive to the SBCHE612RJ
• Inventory availability: SBCHE612RJ has 1623 units in stock versus 675 units for PSP700JB-12R
• Temperature coefficient specification: SBCHE612RJ provides documented ±400ppm/°C temperature coefficient; PSP700JB-12R does not specify this parameter

Frequently Asked Questions (FAQ)

Q: Can SBCHE612RJ replace PSP700JB-12R in all applications?

A: Yes, provided the mechanical package form (axial or radial formed leads) is compatible with your PCB layout. Both parts meet identical electrical specifications: 12 Ohms ±5% at 7W with -55°C ~ 350°C operating range.

Q: What is the difference between axial and radial formed package options?

A: Axial packages have leads extending from opposite ends of the resistor body. Radial formed leads are bent to exit from the same end or side, accommodating different PCB hole patterns and layout requirements. The SBCHE612RJ supports both configurations.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant with EAR99 ECCN classification. The SBCHE612RJ has undefined REACH status from the vendor, while PSP700JB-12R is listed as REACH Unaffected.

Q: Does the temperature coefficient difference affect substitution?

A: The SBCHE612RJ specifies ±400ppm/°C temperature coefficient. The PSP700JB-12R does not provide this specification. If your application requires documented temperature coefficient performance, verify the PSP700JB-12R specification with YAGEO or select the SBCHE612RJ with known characteristics.

Q: What is the moisture sensitivity rating difference?

A: PSP700JB-12R has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. SBCHE612RJ is listed as Not Applicable, typical for wirewound resistors which are inherently moisture-resistant. Both are suitable for standard storage and handling conditions.
