7-1625875-1 Equivalent & Substitute Parts Reference

Part Overview

The 7-1625875-1 is a 1 kOhms ±10% 0.25W axial through-hole resistor manufactured by TE Connectivity Passive Product, utilizing carbon composition construction with pulse withstanding capability. This component operates across the temperature range of -55°C to 125°C and is housed in a standard axial package measuring 0.094" diameter by 0.248" length (2.40mm x 6.30mm).

The 7-1625875-1 is classified as obsolete. Locating equivalent or substitute components becomes necessary when original inventory is depleted or when design requirements permit the use of alternative resistor technologies that offer improved performance characteristics or better availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7-1625875-1 is determined by the following critical parameters:

Resistance Value: The substitute must provide 1 kOhms nominal resistance to maintain circuit function.

Package Configuration: The substitute must utilize axial through-hole packaging with two terminations to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Power Dissipation Capability: The substitute must support the power requirements of the application. The 7-1625875-1 is rated at 0.25W; substitutes rated at 0.333W or higher satisfy this requirement.

Operating Temperature Range: The substitute must encompass or exceed the operating temperature range of -55°C to 125°C.

Tolerance and Composition: While the original part specifies ±10% tolerance with carbon composition construction, substitutes with improved tolerance specifications (such as ±5%) and alternative compositions (such as carbon film) are acceptable when circuit design permits.

The CFR25J1K0 meets all substitution criteria through equivalent resistance value, compatible axial package, superior power rating, extended temperature range, and active product status.

Parameter Comparison

Engineering Selection Recommendations

The CFR25J1K0 is the designated manufacturer-recommended substitute for the 7-1625875-1. Selection of this substitute is supported by the following factors:

Product Status: The CFR25J1K0 maintains active product status, ensuring continued availability and supply chain reliability. The 7-1625875-1 is obsolete, making the CFR25J1K0 the appropriate long-term component choice.

Regulatory Compliance: The CFR25J1K0 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. These certifications support compliance with modern manufacturing and end-use regulations.

Performance Enhancement: The CFR25J1K0 provides improved tolerance specification (±5% versus ±10%), extended operating temperature range (-55°C to 155°C versus -55°C to 125°C), and higher power dissipation capability (0.333W versus 0.25W). These characteristics provide design margin and enhanced reliability.

Physical Compatibility: Both components utilize axial through-hole packaging with two terminations. Physical dimensions are comparable (0.098" diameter x 0.268" length versus 0.094" diameter x 0.248" length), permitting direct substitution in existing PCB layouts without redesign.

Frequently Asked Questions (FAQ)

Q: Can the CFR25J1K0 directly replace the 7-1625875-1 in existing designs?

A: Yes. Both components share identical resistance value (1 kOhms), compatible axial through-hole package configuration, and two-terminal design. Physical dimensions are comparable, and the CFR25J1K0 provides equal or superior electrical performance across all specified parameters.

Q: What are the key differences between these two resistors?

A: The primary differences are composition (carbon composition versus carbon film), tolerance specification (±10% versus ±5%), power rating (0.25W versus 0.333W), operating temperature range (-55°C to 125°C versus -55°C to 155°C), and product status (obsolete versus active). The CFR25J1K0 offers improved specifications in all categories.

Q: Does the improved tolerance of the CFR25J1K0 affect circuit design?

A: The ±5% tolerance of the CFR25J1K0 is tighter than the ±10% tolerance of the 7-1625875-1. This improvement does not negatively affect circuit function; it provides enhanced precision and reduced tolerance stack-up in applications where multiple resistors are used in series or parallel configurations.

Q: Are there any packaging or assembly considerations when substituting these components?

A: Both components are axial through-hole resistors with identical termination count. The CFR25J1K0 is marginally larger (0.098" diameter x 0.268" length versus 0.094" diameter x 0.248" length). This minor dimensional difference does not typically impact PCB layout or assembly processes for standard through-hole applications.

Q: What is the significance of the CFR25J1K0 being ROHS3 compliant?

A: ROHS3 compliance indicates that the CFR25J1K0 meets current European Union Restriction of Hazardous Substances regulations. This certification is essential for products destined for EU markets and reflects adherence to modern environmental and health standards in component manufacturing.

Q: Why is the CFR25J1K0 recommended over other potential 1 kOhms axial resistors?

A: The CFR25J1K0 is the manufacturer-recommended substitute specified by TE Connectivity Passive Product. This designation reflects engineering validation of electrical and mechanical compatibility, ensuring reliable performance in applications originally designed for the 7-1625875-1.
