TE Connectivity 6-1625875-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 6-1625875-5 is a 100 Ohm ±10% 0.25W (1/4W) through-hole resistor with axial leads, constructed using carbon composition material. This component is classified as obsolete, indicating discontinued manufacturing and limited availability in the market. The part operates across a temperature range of -55°C to 125°C and features pulse withstanding capability.

Due to its obsolete status, sourcing original units becomes increasingly difficult. Identifying equivalent substitute parts with compatible electrical and mechanical specifications is essential for maintaining design continuity and ensuring component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

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

Primary Substitution Criteria:

• Resistance value: 100 Ohms (exact match required)
• Package configuration: Axial through-hole leads
• Number of terminations: 2
• Operating temperature range: Must encompass or exceed -55°C to 125°C
• Power rating: Must equal or exceed 0.25W

Secondary Compatibility Factors:

• Tolerance: Substitute tolerance of ±5% is acceptable for applications originally designed for ±10%
• Composition: Carbon film substitutes are acceptable where pulse withstanding is not a critical design requirement
• Packaging format: Cut tape or bulk packaging is acceptable for equivalent electrical performance

The substitute part CFR25J100R meets all primary criteria with enhanced specifications in tolerance and power rating, while maintaining identical resistance value and axial package configuration.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The CFR25J100R is a direct functional equivalent for the 6-1625875-5 based on electrical parameters. Both components share identical resistance values, axial package configurations, and two-terminal designs. The substitute part offers superior specifications including tighter tolerance (±5% versus ±10%), higher power rating (0.333W versus 0.25W), and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C).

Product Status Advantage:

The CFR25J100R maintains active product status with confirmed inventory availability (12,198 pieces in stock), whereas the original 6-1625875-5 is obsolete. This status difference directly supports long-term supply chain reliability and production continuity.

Compliance Considerations:

Both components carry identical ECCN classification (EAR99) and share equivalent export control status. The CFR25J100R includes RoHS3 compliance certification and REACH unaffected status, providing additional regulatory alignment for modern manufacturing environments.

Physical Compatibility:

Dimensional differences are minimal (0.094" to 0.098" diameter; 0.248" to 0.268" length). These variations remain within standard PCB through-hole tolerances and do not require design modifications for board-level integration.

Frequently Asked Questions (FAQ)

Q: Can CFR25J100R directly replace 6-1625875-5 in existing designs?

A: Yes. Both components share identical resistance values (100 Ohms), axial package configuration, and two-terminal design. The substitute part meets or exceeds all electrical specifications of the original component.

Q: What is the significance of the tolerance difference (±10% versus ±5%)?

A: The CFR25J100R tolerance of ±5% is tighter than the original ±10% specification. This represents improved accuracy and is acceptable for all applications originally designed for the 6-1625875-5. No circuit redesign is required.

Q: Does the power rating difference (0.25W versus 0.333W) affect compatibility?

A: No. The higher power rating of the CFR25J100R (0.333W) provides additional thermal margin and is fully compatible with applications designed for 0.25W operation. This represents an enhancement rather than a limitation.

Q: Are there physical installation concerns due to dimensional differences?

A: Dimensional variations between the two parts (approximately 0.004" diameter and 0.020" length differences) are negligible for standard PCB through-hole mounting. No mechanical modifications to PCB layouts are required.

Q: What is the impact of composition change from carbon composition to carbon film?

A: The CFR25J100R carbon film construction provides improved stability and temperature coefficient performance (0/-450ppm/°C). For applications where pulse withstanding is not a critical design requirement, carbon film composition is functionally equivalent and often superior.

Q: How does product status affect component selection?

A: The CFR25J100R active status ensures ongoing availability and supply chain reliability. The 6-1625875-5 obsolete status creates sourcing constraints and potential future unavailability, making the substitute part the preferred selection for new production and long-term applications.

Q: Are there any export or compliance restrictions affecting substitution?

A: Both components carry identical ECCN classification (EAR99). The CFR25J100R includes RoHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment for current manufacturing standards.
