Key Parameters

Substitute Part Grouping Explanation

Substitution of the CFR50J2M7 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CFR-50JB-52-2M7 qualifies as a direct equivalent based on the following matching criteria:

• Identical resistance value: 2.7 MOhms
• Identical tolerance specification: ±5%
• Identical power rating: 0.5W (1/2W)
• Identical composition: Carbon Film
• Identical package configuration: Axial through-hole
• Identical temperature coefficient: 0 / -1500ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical number of terminations: 2

The substitute part is manufactured by YAGEO and maintains active product status, ensuring continued availability for procurement.

Parameter Comparison

Engineering Selection Recommendations

The CFR-50JB-52-2M7 manufactured by YAGEO is the direct equivalent substitute for the obsolete CFR50J2M7. Selection of this substitute part is based on complete electrical parameter equivalence and active product status.

The YAGEO CFR-50JB-52-2M7 provides the following advantages for component selection:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance satisfies regulatory requirements for new designs
• Identical electrical specifications eliminate circuit redesign requirements
• Axial package configuration maintains mechanical compatibility with existing PCB layouts
• Minor physical diameter variation (0.130" versus 0.118") does not impact functional performance or standard PCB hole spacing

The substitute part is suitable for direct replacement in applications where the original CFR50J2M7 was specified.

Frequently Asked Questions (FAQ)

Q: Can the CFR-50JB-52-2M7 be used as a direct replacement for CFR50J2M7?

A: Yes. The CFR-50JB-52-2M7 is electrically and mechanically equivalent to the CFR50J2M7 across all critical parameters including resistance value, tolerance, power rating, composition, package type, and operating temperature range.

Q: What is the significance of the physical diameter difference between the two parts?

A: The CFR50J2M7 has a diameter of 0.118" (3.00mm) while the CFR-50JB-52-2M7 has a diameter of 0.130" (3.30mm). This minor variation does not affect electrical performance or compatibility with standard PCB hole spacing for axial through-hole components.

Q: Why is the CFR50J2M7 listed as obsolete?

A: The CFR50J2M7 is classified as obsolete by TE Connectivity Passive Product. The CFR-50JB-52-2M7 substitute maintains active product status and is recommended for new procurement.

Q: Are there compliance differences between the two parts?

A: The CFR-50JB-52-2M7 is ROHS3 compliant and REACH unaffected. The CFR50J2M7 compliance status is not specified in available documentation. For applications requiring regulatory compliance, the YAGEO substitute is the appropriate selection.

Q: What is the packaging difference between these parts?

A: The CFR50J2M7 is supplied in standard packaging, while the CFR-50JB-52-2M7 is supplied in bulk packaging. Both maintain identical component specifications and performance characteristics.

Q: Are the temperature coefficients identical?

A: Yes. Both parts specify a temperature coefficient of 0 / -1500ppm/°C and operate across the identical temperature range of -55°C to 155°C.
