ESR25JZPJ621 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ621 is a 620 Ohms ±5% thick film chip resistor manufactured by Rohm Semiconductor in the 1210 (3225 Metric) package. Rated for 0.667W (2/3W) power dissipation with automotive AEC-Q200 qualification and pulse withstanding capability, this component operates across -55°C to 155°C. The part is currently active in production with 773 units in stock. Equivalent and substitute parts are identified based on matching resistance value, tolerance, package dimensions, and automotive qualification requirements.

Substitute Part Grouping Explanation

Substitute parts for the ESR25JZPJ621 are qualified based on the following criteria:

• Resistance Value: 620 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Package: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±200ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Automotive Qualification: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Substitute parts may differ in power rating (0.5W vs. 0.667W) and physical height dimensions while maintaining all other electrical and mechanical specifications. Parts with lower power ratings (0.5W) are acceptable substitutes when circuit design permits, as they meet the same resistance, tolerance, package, and automotive qualification requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status)

ERJ-P14J621U, CRCW1210620RJNEA, and RMCF1210JT620R are all active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. These three parts are functionally equivalent to the ESR25JZPJ621 for applications where the 0.5W power rating is sufficient. All maintain identical resistance, tolerance, package dimensions, temperature coefficient, and operating temperature range.

Secondary Substitute (Legacy Status)

ERJ-14YJ621U carries a "Not For New Designs" product status and should be used only in legacy system maintenance or replacement scenarios where the original part specification requires this exact part number. It meets all electrical and mechanical parameters but is not recommended for new circuit designs.

Power Rating Consideration

The ESR25JZPJ621 is rated for 0.667W, while all substitute parts are rated for 0.5W. Substitution is valid only when circuit thermal analysis confirms that the actual power dissipation does not exceed 0.5W under worst-case operating conditions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14J621U replace ESR25JZPJ621 in all applications?

A: ERJ-P14J621U is electrically and mechanically equivalent to ESR25JZPJ621 when the circuit power dissipation does not exceed 0.5W. Both parts share identical resistance (620 Ohms), tolerance (±5%), package (1210), temperature coefficient (±200ppm/°C), operating range (-55°C to 155°C), and AEC-Q200 automotive qualification. Verify that your application's actual power dissipation remains within the 0.5W limit.

Q: What is the difference between CRCW1210620RJNEA and RMCF1210JT620R?

A: Both parts are functionally equivalent with identical electrical specifications (620 Ohms ±5%, 0.5W, ±200ppm/°C, -55°C to 155°C, AEC-Q200). The primary differences are manufacturer (Vishay Dale vs. Stackpole Electronics Inc) and physical height (0.024" vs. 0.028" maximum seated height). Select based on PCB layout constraints and supplier availability.

Q: Why is ERJ-14YJ621U marked "Not For New Designs"?

A: ERJ-14YJ621U is a legacy part that meets all technical specifications but is no longer recommended for new circuit designs. Use this part only for replacement or maintenance of existing systems that specifically require this part number. For new designs, select from active production alternatives: ERJ-P14J621U, CRCW1210620RJNEA, or RMCF1210JT620R.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. ESR25JZPJ621 and all four substitute parts (ERJ-P14J621U, CRCW1210620RJNEA, ERJ-14YJ621U, RMCF1210JT620R) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Can I use a substitute part with lower power rating in a high-temperature environment?

A: All substitute parts operate across the same temperature range (-55°C to 155°C) as the main part. However, power dissipation capability decreases at elevated temperatures. Verify that your circuit's actual power dissipation at maximum operating temperature does not exceed the 0.5W rating of the substitute part.

Q: What is the package compatibility between these parts?

A: All parts use the 1210 (3225 Metric) package with identical footprint dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm). Physical height varies slightly (0.024" to 0.028" maximum seated height), which may affect PCB clearance in space-constrained designs. Verify height clearance for your specific application.
