Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERD-S2TJ511V is determined by the following critical parameters:

• Resistance Value: 510 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Package Type: Axial through-hole (exact match required)
• Composition: Carbon Film (exact match required)
• Operating Temperature Range: -55°C to 155°C (substitute must meet or exceed this range)
• Termination Count: 2 (exact match required)

The CFM14JT510R from Stackpole Electronics Inc meets all substitution criteria. Both parts share identical electrical specifications, package configuration, and operating temperature range. The substitute part is currently in active production status with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The CFM14JT510R is the direct equivalent substitute for the obsolete ERD-S2TJ511V. Selection is based on the following factors:

Electrical Compatibility: Both parts deliver identical resistance, tolerance, and power dissipation characteristics. The operating temperature range is identical, ensuring functional equivalence across all specified environmental conditions.

Physical Compatibility: Axial package configuration is identical. Physical dimensions differ by 0.004" (0.10mm) in length, which is negligible for standard through-hole PCB applications and does not affect lead spacing or mounting.

Production Status: The CFM14JT510R is in active production with significantly higher inventory availability (10,904 pcs vs. 1,133 pcs), ensuring supply chain continuity and cost efficiency.

Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8533.10.0065) classifications. The CFM14JT510R includes RoHS3 compliance and REACH unaffected status, meeting modern regulatory requirements.

Additional Features: The CFM14JT510R includes flame retardant coating and safety features, providing enhanced performance characteristics compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can the CFM14JT510R be used as a direct replacement for the ERD-S2TJ511V?

A: Yes. Both parts are 510 Ohm ±5% 1/4W axial carbon film resistors with identical electrical specifications and operating temperature ranges. The physical dimensions are functionally equivalent for standard through-hole applications.

Q: What is the significance of the slight length difference (0.126" vs. 0.130")?

A: The 0.004" (0.10mm) difference is within standard manufacturing tolerances for axial resistors and does not affect PCB layout, lead spacing, or mounting compatibility.

Q: Why is the ERD-S2TJ511V classified as obsolete?

A: Panasonic has discontinued this product line. The CFM14JT510R from Stackpole Electronics Inc provides equivalent functionality with active production status and improved availability.

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

A: Both parts share identical ECCN and HTSUS classifications. The CFM14JT510R includes RoHS3 compliance and REACH unaffected status, meeting current regulatory standards.

Q: What is the difference in temperature coefficient between these parts?

A: The ERD-S2TJ511V has a temperature coefficient of -150 / -350ppm/°C, while the CFM14JT510R has 0 / -400ppm/°C. Both values are within acceptable ranges for general-purpose carbon film resistor applications and do not affect substitution eligibility.

Q: Is the flame retardant coating on the CFM14JT510R a significant advantage?

A: The flame retardant coating and safety features on the CFM14JT510R provide enhanced performance characteristics. These features do not negatively impact compatibility and may offer improved reliability in certain applications.
