Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CFM12JA620R is determined by strict equivalence in the following parameters:

• Resistance value: 620 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Carbon Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The CF12JT620R qualifies as a direct substitute based on identical electrical specifications and regulatory status. Packaging format differences (Tape & Box versus Cut Tape) do not affect electrical or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CFM12JA620R and CF12JT620R are active production parts manufactured by Stackpole Electronics Inc with identical electrical and thermal specifications. Selection between these parts is determined by packaging and inventory requirements rather than functional performance. The CFM12JA620R is supplied in Tape & Box format with 950 units in stock, while the CF12JT620R is supplied in Cut Tape format with 31,465 units in stock. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component applications.

Frequently Asked Questions (FAQ)

Q: Can CF12JT620R replace CFM12JA620R in existing circuit designs?

A: Yes. Both parts are electrically and mechanically identical with matching resistance values, tolerance, power ratings, temperature coefficients, and operating temperature ranges. The difference in packaging format (Tape & Box versus Cut Tape) does not affect circuit performance or component installation.

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box packaging supplies components on tape with a protective box, typically used for smaller order quantities. Cut Tape packaging supplies components on tape without the box, typically used for higher-volume orders. Both formats contain identical components suitable for automated or manual assembly.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts share identical temperature coefficients (-400ppm/°C), operating temperature ranges (-55°C to 155°C), and power dissipation characteristics (0.5W). Thermal and electrical performance in circuit applications is equivalent.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both CFM12JA620R and CF12JT620R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use in regulated markets.

Q: What factors should determine part selection between these two options?

A: Selection should be based on packaging format preference, inventory availability, and supply chain requirements. The CF12JT620R offers significantly higher stock availability (31,465 units versus 950 units), which may be relevant for high-volume production or extended lead time mitigation.
