Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7-1625875-7 is determined by the following critical parameters:

Resistance Value: The substitute part must provide 10 kOhms nominal resistance to maintain circuit function.

Package Configuration: Both the main part and substitute must utilize axial through-hole packaging to ensure mechanical and electrical compatibility with existing PCB layouts.

Power Rating: The substitute part must meet or exceed the 0.25W power dissipation requirement. The CFR25J10K provides 0.333W (1/3W), which exceeds this specification.

Tolerance: The main part specifies ±10% tolerance. The substitute CFR25J10K provides ±5% tolerance, which is tighter and therefore acceptable for applications requiring the original tolerance or better.

Operating Temperature Range: The substitute must support the operating temperature envelope of -55°C ~ 125°C. The CFR25J10K supports -55°C ~ 155°C, which encompasses the original range.

Product Status: The substitute must be active and available for procurement to address the obsolescence of the original part.

Parameter Comparison

Engineering Selection Recommendations

The CFR25J10K is the designated manufacturer-recommended substitute for the obsolete 7-1625875-7. This substitution is supported by the following factors:

Electrical Compatibility: Both parts provide identical 10 kOhms resistance. The CFR25J10K's ±5% tolerance is superior to the original ±10% specification, ensuring tighter resistance values. The 0.333W power rating of the CFR25J10K exceeds the 0.25W requirement of the original part, providing additional thermal margin.

Mechanical Compatibility: Both parts utilize axial through-hole packaging with two terminations, ensuring direct PCB layout compatibility without redesign.

Thermal Performance: The CFR25J10K operating temperature range of -55°C ~ 155°C fully encompasses the original -55°C ~ 125°C specification, with extended upper temperature capability.

Regulatory Compliance: The CFR25J10K is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original part's compliance status is not specified.

Product Availability: The CFR25J10K is active and maintains substantial inventory (24,844 pcs), ensuring procurement continuity and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the CFR25J10K be used as a direct replacement for the 7-1625875-7 in existing designs?

A: Yes. Both parts share identical resistance values, axial package configuration, and two-terminal design. The CFR25J10K's superior tolerance (±5% vs ±10%), higher power rating (0.333W vs 0.25W), and extended operating temperature range (-55°C ~ 155°C vs -55°C ~ 125°C) make it functionally compatible for direct substitution without circuit modification.

Q: What is the primary difference between the 7-1625875-7 and CFR25J10K?

A: The main differences are composition type (carbon composition vs carbon film), power rating (0.25W vs 0.333W), tolerance (±10% vs ±5%), and product status (obsolete vs active). The CFR25J10K provides improved electrical performance and regulatory compliance.

Q: Are there any mechanical considerations when substituting these parts?

A: Both parts utilize axial through-hole packaging with identical termination count (2). Physical dimensions are similar (7-1625875-7: 0.094" Dia x 0.248" L; CFR25J10K: 0.098" Dia x 0.268" L), with negligible differences that do not affect PCB layout compatibility.

Q: Does the CFR25J10K meet current environmental standards?

A: Yes. The CFR25J10K is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Why is the 7-1625875-7 classified as obsolete?

A: The 7-1625875-7 is listed as obsolete by the manufacturer. The CFR25J10K is the active equivalent part recommended for new designs and ongoing production.
