ESR25JZPJ112 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ112 is a 1.1 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in the 1210 (3225 Metric) package. This automotive-grade component features AEC-Q200 certification and pulse withstanding capability, rated for 0.667W (2/3W) power dissipation across an operating temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives that maintain electrical and mechanical compatibility within the same package footprint and performance envelope.

Substitute Part Grouping Explanation

Substitution eligibility for the ESR25JZPJ112 is determined by the following mandatory parameters:

• Resistance value: 1.1 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Package / Case: 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 Rating: AEC-Q200 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The identified substitute parts meet all mandatory electrical and mechanical parameters. Variations in power rating (0.5W vs. 0.667W) and physical height do not disqualify substitution when the application circuit design accommodates the lower power specification. Product status differences are noted for design planning purposes.

Parameter Comparison

Engineering Selection Recommendations

ERJ-P14J112U (Panasonic) is the primary substitute for new designs and ongoing production. This part maintains active product status, identical electrical specifications, and full AEC-Q200 automotive compliance. The 0.5W power rating is suitable for applications where circuit design accommodates this specification. Tape & Reel packaging aligns with high-volume manufacturing processes.

ERJ-14YJ112U (Panasonic) is designated "Not For New Designs" and should be reserved for legacy system support or maintenance applications only. While electrically and mechanically compatible, this part's discontinued design status makes it unsuitable for new product development or long-term production commitments.

Both Panasonic alternatives are electrically interchangeable with the ESR25JZPJ112 when power dissipation requirements do not exceed 0.5W. Physical height variation (0.028" vs. 0.026") is negligible for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14J112U replace ESR25JZPJ112 in all applications?

A: ERJ-P14J112U is electrically and mechanically compatible when the circuit design accommodates the 0.5W power rating. If the application requires the full 0.667W capability of the ESR25JZPJ112, power dissipation analysis must confirm that actual operating conditions remain below 0.5W.

Q: What is the significance of the "Not For New Designs" status on ERJ-14YJ112U?

A: This designation indicates the part is in end-of-life phase. While currently available in inventory, Panasonic does not recommend its use in new product designs. It should be used only for replacement or repair of existing systems.

Q: Are there packaging differences between the substitute parts?

A: ESR25JZPJ112 and ERJ-P14J112U are supplied in Tape & Reel format suitable for automated assembly. ERJ-14YJ112U is available in Cut Tape and Digi-Reel formats, which may require different handling in high-volume production environments.

Q: Do all three parts meet automotive qualification requirements?

A: Yes. ESR25JZPJ112, ERJ-P14J112U, and ERJ-14YJ112U all carry AEC-Q200 certification and are suitable for automotive applications within their specified operating parameters.

Q: What is the physical height difference, and does it matter?

A: ESR25JZPJ112 has a maximum seated height of 0.026" (0.65mm), while both Panasonic alternatives measure 0.028" (0.70mm). This 0.002" difference is within standard PCB assembly tolerances and does not affect board-level compatibility.
