Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CF12JA47R0 is determined by strict equivalence in the following parameters:

• Resistance value: 47 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 type: Axial (exact match required)
• Temperature coefficient: 0 / -400ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The CFM12JA47R0 qualifies as a direct substitute based on identical electrical and environmental specifications. The primary difference is packaging configuration: CF12JA47R0 is supplied in Tape & Box (TB) format, while CFM12JA47R0 is supplied in Cut Tape (CT) format. Both maintain the same axial component dimensions and termination characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both CF12JA47R0 and CFM12JA47R0 are active production parts with full ROHS3 compliance and REACH unaffected status, making either suitable for applications requiring regulatory compliance. Selection between these parts should be based on packaging requirements and inventory availability. The CFM12JA47R0 offers higher stock availability (2452 units versus 858 units) and is supplied in Cut Tape format, which may be advantageous for automated assembly processes. The CF12JA47R0 in Tape & Box format may be preferred for manual assembly or smaller batch operations. Both parts maintain identical electrical performance and environmental operating specifications.

Frequently Asked Questions (FAQ)

Q: Can CFM12JA47R0 be used as a direct replacement for CF12JA47R0?

A: Yes. Both parts are electrically and functionally identical with matching resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The primary difference is packaging format (Cut Tape versus Tape & Box).

Q: What is the difference in physical dimensions between these parts?

A: CF12JA47R0 measures 0.106" diameter x 0.335" length (2.70mm x 8.50mm). CFM12JA47R0 measures 0.091" diameter x 0.256" length (2.30mm x 6.50mm). Both are axial package types suitable for through-hole PCB mounting.

Q: Are both parts RoHS compliant?

A: Yes. Both CF12JA47R0 and CFM12JA47R0 are ROHS3 compliant and REACH unaffected.

Q: Which part should I select for high-volume production?

A: Selection should be based on assembly process requirements. CFM12JA47R0 in Cut Tape format is typically preferred for automated pick-and-place assembly. CF12JA47R0 in Tape & Box format may be suitable for manual assembly or lower-volume applications.

Q: Do these parts have identical temperature performance?

A: Yes. Both parts operate across -55°C to 155°C with identical temperature coefficient specifications of 0 / -400ppm/°C.
