ESR25JZPJ751 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ751 is a 750 Ohm ±5% thick film chip resistor manufactured by Rohm Semiconductor in the 1210 (3225 Metric) package. This component is rated for 0.667W (2/3W) power dissipation and meets automotive AEC-Q200 qualification with pulse withstanding capability. The part is currently in active production status with 852 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life, experiences supply constraints, or when design requirements allow for compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR25JZPJ751 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 750 Ohms
• Tolerance: ±5%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±200ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Automotive Rating: AEC-Q200
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Flexible Parameter:

• Power Rating: The ESR25JZPJ751 is rated at 0.667W (2/3W). Substitute parts rated at 0.5W (1/2W) are acceptable in applications where the circuit design does not require the full 0.667W dissipation capacity, as the lower power rating represents a conservative design margin.

All identified substitute parts maintain identical electrical characteristics (resistance, tolerance, temperature coefficient, operating range) and package dimensions while meeting the same automotive and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

ERJ-P14J751U (Panasonic Electronic Components) and RMCF1210JT750R (Stackpole Electronics Inc) are the preferred substitutes. Both parts maintain active production status, ensuring long-term availability and supply chain stability. ERJ-P14J751U is supplied in Tape & Reel packaging, while RMCF1210JT750R is available in Cut Tape format. Both meet all AEC-Q200 automotive qualifications and ROHS3 compliance requirements.

CRCW1210750RJNEA (Vishay Dale) is an alternative substitute with active status and equivalent electrical specifications. This part offers the lowest seated height at 0.024" (0.60mm) compared to other substitutes.

Secondary Substitute (Legacy Status):

ERJ-14YJ751U (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. While electrically and mechanically compatible, this part should not be selected for new circuit designs. It remains suitable only for legacy system maintenance or repair applications where the original part specification must be maintained.

Power Rating Consideration:

All substitute parts are rated at 0.5W (1/2W) compared to the ESR25JZPJ751 at 0.667W (2/3W). Selection of these substitutes is appropriate when circuit analysis confirms that the actual power dissipation at this resistor location does not exceed 0.5W under maximum operating conditions.

Frequently Asked Questions (FAQ)

Q: Can I use a 0.5W (1/2W) rated resistor as a substitute for the 0.667W (2/3W) ESR25JZPJ751?

A: Yes, provided circuit analysis confirms that the actual power dissipation at this resistor location remains below 0.5W under all operating conditions including worst-case scenarios. The lower power rating represents a more conservative design margin and is acceptable for direct substitution when this condition is met.

Q: Are all substitute parts compatible with the same PCB footprint as the ESR25JZPJ751?

A: Yes. All substitute parts use the 1210 (3225 Metric) package with identical length (0.126" / 3.20mm) and width (0.098" / 2.50mm) dimensions. Seated heights vary slightly between manufacturers (0.024" to 0.028"), but these variations fall within standard PCB assembly tolerances and do not affect footprint compatibility.

Q: Which substitute part offers the best long-term supply availability?

A: RMCF1210JT750R (Stackpole Electronics Inc) currently has the highest inventory level at 36,694 units. ERJ-P14J751U (Panasonic) follows with 21,475 units. Both parts maintain active production status, supporting sustained availability for future procurement.

Q: Why is ERJ-14YJ751U marked as "Not For New Designs"?

A: This designation indicates that the manufacturer has transitioned this part to legacy status and is not recommending it for incorporation into new circuit designs. While the part remains electrically and mechanically compatible, it should be reserved for maintenance and repair of existing systems only.

Q: Do all substitute parts meet automotive AEC-Q200 qualification?

A: Yes. All identified substitute parts carry AEC-Q200 automotive qualification, ensuring compliance with automotive industry reliability and quality standards. All parts are also ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging is supplied on continuous reels suitable for high-volume automated assembly. Cut Tape packaging is supplied in smaller quantities on tape segments, typically used for lower-volume applications or manual assembly. Both packaging formats contain identical components; the difference is in supply format and handling method.
