Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERD-S1TJ240V is determined by strict equivalence across the following critical parameters:

• Resistance value: 24 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: Axial through-hole (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• Termination count: 2 leads (exact match required)

The CFM12JT24R0 from Stackpole Electronics Inc meets all substitution criteria. This part maintains identical electrical specifications and physical form factor while offering active product status and enhanced features including flame retardant coating and safety certification.

Engineering Selection Recommendations

The CFM12JT24R0 is the direct substitute for the obsolete ERD-S1TJ240V. Selection is based on the following factors:

• Electrical equivalence: Identical resistance, tolerance, and power rating specifications ensure functional compatibility in circuit applications.
• Physical compatibility: Axial package dimensions are equivalent within manufacturing tolerances (length variance of 0.006" is within standard PCB layout tolerances).
• Product status: The CFM12JT24R0 maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance: Both parts share identical ECCN and HTSUS classifications. The CFM12JT24R0 carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements.
• Enhanced features: The Stackpole part includes flame retardant coating and safety certification, providing additional performance characteristics over the original Panasonic component.

Frequently Asked Questions (FAQ)

Q: Can the CFM12JT24R0 be used as a direct replacement for the ERD-S1TJ240V in existing designs?

A: Yes. The CFM12JT24R0 meets all electrical and mechanical specifications required for direct substitution. The axial package dimensions are equivalent, and the part fits standard through-hole PCB layouts designed for the ERD-S1TJ240V.

Q: What is the significance of the length difference (0.250" vs 0.256")?

A: The 0.006" length difference is within standard manufacturing tolerances for axial resistors and does not affect PCB layout or circuit performance. Both parts maintain the same 0.091" diameter and two-lead termination configuration.

Q: Why is the ERD-S1TJ240V classified as obsolete?

A: Panasonic has discontinued this product line. The CFM12JT24R0 provides equivalent functionality with active manufacturer support and modern compliance certifications.

Q: Are there any compliance differences between the two parts?

A: The CFM12JT24R0 includes ROHS3 compliance and REACH unaffected status. Both parts share the same ECCN (EAR99) and HTSUS (8533.10.0065) classifications, ensuring equivalent regulatory treatment.

Q: What does the flame retardant coating on the CFM12JT24R0 provide?

A: The flame retardant coating and safety certification on the Stackpole part represent enhanced material specifications. This does not alter the electrical performance but provides additional safety characteristics for applications requiring enhanced thermal stability.
