Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 5-1879361-3 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

• Resistance value: 20 kOhms (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±10ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Number of Terminations: 2 (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Parameters Allowing Variation:

• Tolerance: The main part specifies ±0.1%. Substitute parts with equal or tighter tolerance (±0.05%) are acceptable as they meet or exceed the original specification.
• Power Rating: The main part specifies 0.063W (1/16W). Substitute parts with equal or higher power ratings (0.1W / 1/10W) are acceptable as they provide equal or enhanced capability.
• Physical Dimensions: Minor variations in length (0.061" to 0.063") and height (0.020" to 0.022") are acceptable within the 0603 package specification.

All identified substitute parts maintain compatibility with the original part across all critical parameters while offering equivalent or enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Stackpole RNCF0603BKT20K0

This substitute part maintains identical tolerance (±0.1%) and temperature coefficient specifications as the original TE Connectivity component. The RNCF series provides enhanced power rating (0.1W versus 0.063W) and includes Automotive AEC-Q200 certification. RoHS3 compliance and REACH Unaffected status provide regulatory advantages. This part is suitable for direct replacement in applications where automotive qualification is beneficial or required.

Panasonic ERA-3ARB203V

This upgrade option maintains the ±0.1% tolerance specification while providing increased power rating (0.1W) and Automotive AEC-Q200 certification. The ERA-3A series offers ROHS3 compliance and REACH Unaffected status. High inventory availability (22,497 pieces) supports supply chain continuity. This part is appropriate for applications requiring automotive-grade components with standard tolerance specifications.

Panasonic ERA-3ARW203V

This upgrade option provides tighter tolerance (±0.05% versus ±0.1%) and increased power rating (0.1W). The ERA-3A series includes Automotive AEC-Q200 certification with ROHS3 compliance and REACH Unaffected status. Selection of this part is appropriate for precision applications requiring enhanced tolerance performance and automotive qualification.

Susumu RG1608N-203-W-T5

This upgrade option combines tighter tolerance (±0.05%), increased power rating (0.1W), and Anti-Sulfur feature with Automotive AEC-Q200 certification. The RG series provides ROHS3 compliance and REACH Unaffected status. The Anti-Sulfur feature provides enhanced reliability in corrosive environments. This part is suitable for demanding automotive and industrial applications requiring superior environmental protection.

Frequently Asked Questions (FAQ)

Q: Can the Stackpole RNCF0603BKT20K0 directly replace the TE Connectivity 5-1879361-3?

A: Yes. Both parts share identical resistance value (20 kOhms), tolerance (±0.1%), package (0603), composition (thin film), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C to 155°C). The Stackpole part provides higher power rating (0.1W versus 0.063W), which is a non-limiting enhancement. Automotive AEC-Q200 certification is an additional qualification benefit.

Q: What is the difference between the Panasonic ERA-3ARB203V and ERA-3ARW203V?

A: Both parts are identical except for tolerance specification. The ERA-3ARB203V maintains ±0.1% tolerance matching the original part. The ERA-3ARW203V provides tighter ±0.05% tolerance. Both share identical power rating (0.1W), package (0603), and automotive certification. Selection depends on application precision requirements.

Q: Are all substitute parts automotive-qualified?

A: Yes. All identified substitute parts (Stackpole RNCF0603BKT20K0, Panasonic ERA-3ARB203V, Panasonic ERA-3ARW203V, and Susumu RG1608N-203-W-T5) carry Automotive AEC-Q200 certification. The original TE Connectivity 5-1879361-3 does not specify automotive qualification.

Q: What does the Anti-Sulfur feature on the Susumu RG1608N-203-W-T5 provide?

A: The Anti-Sulfur feature enhances component reliability in environments with corrosive sulfur compounds. This is particularly beneficial in industrial and automotive applications subject to atmospheric contamination or harsh operating conditions.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist within the 0603 package specification. The TE Connectivity and Stackpole parts measure 0.061" length, while Panasonic and Susumu parts measure 0.063" length. Height specifications range from 0.020" to 0.022". These variations remain within standard 0603 package tolerances and do not affect PCB layout compatibility.

Q: Do all substitute parts meet current regulatory compliance standards?

A: All substitute parts are ROHS3 compliant and REACH Unaffected. The original TE Connectivity part shows "Not applicable" for RoHS status and "Vendor Undefined" for REACH status. Substitute parts provide enhanced regulatory documentation and compliance assurance.

Q: Can substitute parts with higher power ratings be used in circuits designed for the original 0.063W part?

A: Yes. Higher power ratings (0.1W) are non-limiting enhancements. The substitute parts dissipate power more efficiently than the original specification, reducing thermal stress on the component and surrounding circuitry.

Q: Which substitute part offers the best overall performance upgrade?

A: The Susumi RG1608N-203-W-T5 provides the most comprehensive upgrade, combining tighter tolerance (±0.05%), higher power rating (0.1W), Anti-Sulfur protection, and Automotive AEC-Q200 certification. Selection should align with specific application requirements for tolerance, environmental protection, and automotive qualification.
