ES3W100RJ Equivalent & Substitute Parts

Part Overview

The ES3W100RJ is a 100 Ohm ±5% 3W axial wirewound resistor manufactured by TE Connectivity Passive Product. This component is classified as obsolete, though 728 pieces remain in stock as new original inventory. The resistor features flame proof and safety construction suitable for through-hole applications requiring high power dissipation in compact axial packages.

Due to the obsolete product status of the ES3W100RJ, identifying equivalent and substitute parts is necessary for ongoing design support, production continuity, and long-term component availability. Active alternative parts with identical electrical specifications and compatible mechanical dimensions are available from multiple manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES3W100RJ is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 100 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound

Mechanical Compatibility Requirements:

• Package type: Axial
• Number of terminations: 2
• Physical dimensions: Compatible with through-hole PCB layouts

Regulatory & Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99

All substitute parts listed meet these core requirements. Variations in physical dimensions, temperature coefficients, operating temperature ranges, and specific safety features (flame proof vs. flame retardant coating) are secondary considerations that do not prevent functional substitution in most applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: PNP3WVJR-73-100R (YAGEO)

The PNP3WVJR-73-100R is the optimal direct substitute for the ES3W100RJ. This part maintains identical electrical specifications (100 Ohms ±5% 3W wirewound) and physical dimensions (0.217" Dia x 0.512" L). The component is active in production status with 2640 pieces in stock, ensuring long-term availability. Both parts are ROHS3 compliant and REACH unaffected. The PNP3WVJR-73-100R features flame retardant coating and safety construction, providing equivalent functional performance to the original flame proof design.

Secondary Recommendation: 23J100E (Ohmite)

The 23J100E serves as an upgrade alternative with superior temperature coefficient performance (±30ppm/°C versus ±300ppm/°C). Physical dimensions are nearly identical (0.220" Dia x 0.516" L), with minimal variation suitable for standard through-hole PCB layouts. This part is active in production with 749 pieces available. The 23J100E is ROHS3 compliant and REACH unaffected.

Alternative Recommendation: CB3JB100R (Stackpole Electronics Inc)

The CB3JB100R provides an alternative with extended operating temperature range (-55°C ~ 275°C) and improved temperature coefficient (±200ppm/°C). This part features flame proof and moisture resistant construction. Physical dimensions are larger (0.315" Square x 0.866" L), requiring verification of PCB layout compatibility. The component is active in production with 1142 pieces in stock and is ROHS3 compliant and REACH unaffected.

Compact Alternative: PNP300JR-73-100R (YAGEO)

The PNP300JR-73-100R is a compact variant with reduced physical dimensions (0.181" Dia x 0.453" L). This part is suitable for space-constrained applications while maintaining identical electrical specifications. The component is active in production with 39627 pieces in stock, providing excellent availability. ROHS3 compliance and REACH unaffected status are confirmed.

All substitute parts meet mandatory regulatory requirements and provide functional equivalence to the obsolete ES3W100RJ.

Frequently Asked Questions (FAQ)

Q: Can the PNP3WVJR-73-100R directly replace the ES3W100RJ without PCB modifications?

A: Yes. The PNP3WVJR-73-100R maintains identical electrical specifications and physical dimensions to the ES3W100RJ, enabling direct substitution without PCB layout changes.

Q: What is the difference between flame proof and flame retardant coating?

A: Flame proof construction (ES3W100RJ) and flame retardant coating (PNP3WVJR-73-100R, 23J100E) are both safety features. Flame retardant coating is the modern equivalent standard used in active production parts. Both provide equivalent safety performance in typical applications.

Q: Why does the CB3JB100R have larger physical dimensions?

A: The CB3JB100R uses a different mechanical design (0.315" Square x 0.866" L) compared to the cylindrical axial format of other alternatives. This larger form factor accommodates extended operating temperature range (-55°C ~ 275°C) and moisture resistant features. PCB layout compatibility must be verified before selection.

Q: Is the PNP300JR-73-100R suitable for all applications requiring the ES3W100RJ?

A: The PNP300JR-73-100R provides electrical equivalence but features reduced physical dimensions (0.181" Dia x 0.453" L). Applications with space constraints benefit from this compact form factor. Verify that reduced size does not impact thermal dissipation requirements or mechanical mounting in your specific design.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (PNP3WVJR-73-100R, 23J100E, CB3JB100R, PNP300JR-73-100R) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the temperature coefficient significance when selecting a substitute?

A: Temperature coefficient indicates resistance value drift with temperature change. The ES3W100RJ has ±300ppm/°C, while the 23J100E offers superior stability at ±30ppm/°C. For applications with strict tolerance requirements across temperature ranges, the 23J100E provides better performance. For standard applications, all alternatives are functionally equivalent.

Q: Which substitute part has the highest inventory availability?

A: The PNP300JR-73-100R has the highest inventory with 39627 pieces in stock, followed by PNP3WVJR-73-100R with 2640 pieces. Both ensure long-term supply continuity.
