Substitute Part Grouping Explanation

Substitution of the 5-1625875-6 is determined by the following critical parameters:

Resistance Value: Both the main part and substitute maintain 1 Ohms nominal resistance, ensuring functional equivalence in circuit applications.

Package Configuration: Both components utilize axial through-hole packaging with 2 terminations, permitting direct physical replacement on printed circuit boards without layout modification.

Operating Temperature Range: The main part operates from -55°C to 125°C. The substitute extends this range to -55°C to 155°C, providing enhanced thermal performance without compromising lower temperature operation.

Power Dissipation: The main part is rated at 0.25W (1/4W). The substitute provides 0.333W (1/3W) power rating, representing a 33% increase in power handling capacity while maintaining compatibility in applications designed for the original specification.

Tolerance and Accuracy: The main part specifies ±10% tolerance. The substitute offers improved ±5% tolerance, providing tighter resistance value control.

Composition: The main part uses carbon composition construction. The substitute employs carbon film construction, which is a standard evolution in resistor technology offering improved stability and temperature coefficient performance.

Parameter Comparison

Engineering Selection Recommendations

The CFR25J1R0 is the manufacturer-recommended substitute for the obsolete 5-1625875-6. Selection of this substitute is supported by the following factors:

Product Status: The main part is classified as obsolete, while the substitute maintains active product status with confirmed inventory availability (1054 Pcs New Original In Stock). This ensures long-term supply chain reliability and continued manufacturing support.

Regulatory Compliance: The substitute is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component procurement. The main part does not specify these compliance certifications.

Physical Compatibility: Both components share axial through-hole packaging with identical termination configuration (2 leads), enabling direct board-level replacement without circuit redesign or layout modification.

Electrical Performance Enhancement: The substitute provides improved tolerance (±5% versus ±10%), increased power rating (0.333W versus 0.25W), and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C), delivering superior performance margins in the same physical footprint.

Dimensional Considerations: The substitute exhibits minor dimensional increases (0.098" Dia x 0.268" L versus 0.094" Dia x 0.248" L). These differences remain within standard axial resistor form factor tolerances and do not impact PCB mounting compatibility for applications designed with standard component spacing.

Frequently Asked Questions (FAQ)

Q: Can the CFR25J1R0 directly replace the 5-1625875-6 on existing circuit boards?

A: Yes. Both components utilize identical axial through-hole packaging with 2 terminations. The minor dimensional differences (0.004" diameter increase and 0.020" length increase) fall within standard axial resistor form factor tolerances and do not affect PCB mounting compatibility.

Q: What is the significance of the tolerance change from ±10% to ±5%?

A: The substitute provides tighter resistance value control. In applications where the original ±10% tolerance was acceptable, the ±5% tolerance of the substitute offers improved accuracy without introducing incompatibility. Applications requiring specific tolerance bands should verify that ±5% meets circuit requirements.

Q: Does the power rating increase from 0.25W to 0.333W affect circuit operation?

A: No. The higher power rating of the substitute provides additional thermal margin and pulse handling capability. Applications designed for 0.25W operation remain fully compatible with the 0.333W rated substitute.

Q: Are there any temperature range considerations for substitution?

A: The substitute extends the upper operating temperature limit from 125°C to 155°C. The lower limit remains -55°C for both parts. Applications operating within the original -55°C to 125°C range experience no change in performance. Applications requiring operation above 125°C benefit from the extended range of the substitute.

Q: What is the difference between carbon composition and carbon film construction?

A: Both are resistive element technologies. Carbon film construction, used in the substitute, represents standard modern resistor technology offering improved temperature coefficient stability (±350ppm/°C specified for the substitute) compared to carbon composition. Both technologies are suitable for general-purpose through-hole applications.

Q: Is the substitute available in the same packaging format?

A: The main part packaging is not specified in available documentation. The substitute is supplied in Tape & Box (TB) packaging, which is standard for active production components and facilitates automated assembly processes.

Q: What compliance certifications apply to the substitute?

A: The CFR25J1R0 is ROHS3 Compliant and REACH Unaffected. Both components carry EAR99 export classification. These certifications ensure compliance with current environmental regulations and export control requirements.
