Substitute Part Grouping Explanation

Substitution of the KTR25JZPJ515 is permissible with parts that maintain the following critical parameters:

• Resistance value: 5.1 MOhms (exact match required)
• Package / Case: 1210 (3225 Metric) (mechanical compatibility)
• Power rating: 0.333W minimum (electrical capability)
• Operating temperature range: -55°C ~ 155°C minimum (thermal compatibility)
• Automotive qualification: AEC-Q200 (compliance requirement)
• RoHS3 compliance (regulatory requirement)

The KTR25JZPF5104 qualifies as a direct substitute. While it features improved tolerance (±1% versus ±5%), all other critical parameters remain equivalent or superior, ensuring functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The KTR25JZPF5104 is a qualified substitute for the KTR25JZPJ515. Both parts are manufactured by Rohm Semiconductor, carry active product status, and maintain full AEC-Q200 automotive qualification and ROHS3 compliance. The substitute part offers improved tolerance specification (±1% versus ±5%) and lower temperature coefficient (±100ppm/°C versus ±200ppm/°C), making it suitable for applications requiring tighter resistance accuracy. Mechanical and thermal compatibility is assured through identical package dimensions and operating temperature range. Selection between these parts depends on circuit tolerance requirements and application-specific precision specifications.

Frequently Asked Questions (FAQ)

Q: Can KTR25JZPF5104 be used as a direct replacement for KTR25JZPJ515?

A: Yes. Both parts share identical resistance value (5.1 MOhms), package type (1210), power rating (0.333W), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. Physical dimensions and termination count are identical, ensuring PCB compatibility.

Q: What is the difference between these two parts?

A: The primary differences are tolerance and temperature coefficient. KTR25JZPF5104 provides ±1% tolerance compared to ±5% for KTR25JZPJ515, and features a lower temperature coefficient (±100ppm/°C versus ±200ppm/°C). Both are thick film compositions from the same manufacturer series.

Q: Are both parts suitable for automotive applications?

A: Yes. Both KTR25JZPJ515 and KTR25JZPF5104 carry AEC-Q200 qualification, confirming suitability for automotive environments. Both maintain ROHS3 compliance and MSL Level 1 (unlimited moisture sensitivity).

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm) and maximum seated height (0.026" / 0.65mm). No PCB layout modifications are required.

Q: Which part should I select for precision circuits?

A: Selection depends on circuit tolerance requirements. KTR25JZPF5104 with ±1% tolerance is appropriate for applications requiring tighter resistance accuracy. KTR25JZPJ515 with ±5% tolerance is suitable for general-purpose applications where wider tolerance is acceptable.
