Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES3W150RJ is determined by the following core parameters: resistance value (150 Ohms), tolerance (±5%), power rating (3W), composition (wirewound), and package configuration (axial through-hole). All substitute parts listed maintain these electrical and mechanical specifications. Substitutes are grouped based on product status and packaging format:

Direct Substitutes (Active Status): Parts that maintain identical electrical specifications and axial package geometry with current manufacturing status.

Upgrade Substitutes (Enhanced Performance): Parts that meet or exceed the original specifications with improved temperature coefficient performance or enhanced compliance certifications.

Similar Substitutes (Dimensional Variation): Parts that maintain all electrical specifications but feature minor dimensional differences within the axial package category.

Parameter Comparison

Engineering Selection Recommendations

PNP3WVJR-73-150R (YAGEO): This direct substitute maintains identical electrical specifications and physical dimensions to the ES3W150RJ. The part is active in production with ROHS3 compliance and REACH unaffected status. Operating temperature range of -40°C to 200°C is specified. Packaging in Tape & Reel format supports automated assembly processes. This substitute is suitable for direct replacement in new designs and legacy system support.

23J150E (Ohmite): This upgrade substitute offers superior temperature coefficient performance (±30ppm/°C versus ±300ppm/°C of the original), resulting in improved stability across temperature variations. Physical dimensions are within acceptable tolerance for axial package mounting (0.220" Dia x 0.516" L). The part maintains active production status with RoHS compliance. Bulk packaging format is available. This substitute is recommended for applications requiring enhanced temperature stability.

PNP300JR-73-150R (YAGEO): This similar substitute maintains all electrical specifications but features reduced physical dimensions (0.181" Dia x 0.453" L). The part is active in production with ROHS3 compliance and REACH unaffected status. Operating temperature range of -40°C to 200°C is specified. Cut Tape packaging format is available with highest inventory levels (6879 Pcs). This substitute is suitable for space-constrained applications where reduced component size is beneficial.

Frequently Asked Questions (FAQ)

Q: Can PNP3WVJR-73-150R be used as a direct replacement for ES3W150RJ?

A: Yes. PNP3WVJR-73-150R maintains identical electrical specifications (150 Ohms, ±5%, 3W) and physical dimensions (0.217" Dia x 0.512" L). Both parts are axial wirewound resistors with two terminations. The substitute is active in production with ROHS3 compliance.

Q: What is the primary advantage of 23J150E over the original ES3W150RJ?

A: The 23J150E provides a temperature coefficient of ±30ppm/°C compared to ±300ppm/°C for the ES3W150RJ. This represents a tenfold improvement in temperature stability, making it suitable for precision applications requiring minimal resistance drift across operating temperature ranges.

Q: Are there dimensional differences between substitute parts?

A: Yes. PNP3WVJR-73-150R matches the original dimensions exactly (0.217" Dia x 0.512" L). The 23J150E has slightly larger dimensions (0.220" Dia x 0.516" L), and PNP300JR-73-150R is significantly smaller (0.181" Dia x 0.453" L). All remain within the axial package category and are suitable for through-hole mounting.

Q: Which substitute offers the best availability?

A: PNP300JR-73-150R has the highest inventory level at 6879 Pcs in stock. PNP3WVJR-73-150R has 998 Pcs available, and 23J150E has 700 Pcs available.

Q: Do all substitutes meet RoHS compliance requirements?

A: Yes. All substitute parts are RoHS compliant. PNP3WVJR-73-150R and PNP300JR-73-150R are ROHS3 compliant. The 23J150E is RoHS compliant.

Q: What packaging formats are available for each substitute?

A: PNP3WVJR-73-150R is supplied in Tape & Reel (TR) format for automated assembly. PNP300JR-73-150R is supplied in Cut Tape (CT) format. The 23J150E is supplied in Bulk format.

Q: Are operating temperature ranges specified for all parts?

A: Operating temperature ranges are specified for both YAGEO substitutes (PNP3WVJR-73-150R and PNP300JR-73-150R) at -40°C to 200°C. Operating temperature ranges are not specified for the original ES3W150RJ or the 23J150E Ohmite substitute.

Q: Can PNP300JR-73-150R be used in space-constrained PCB layouts?

A: Yes. PNP300JR-73-150R features reduced dimensions (0.181" Dia x 0.453" L) compared to the original ES3W150RJ (0.217" Dia x 0.512" L), making it suitable for compact board designs while maintaining all electrical specifications.
