AC1210FR-0728KL Equivalent & Substitute Parts

Part Overview

The AC1210FR-0728KL is a 28 kOhms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by YAGEO. This component is rated for automotive applications under AEC-Q200 standard with moisture-resistant construction. The part is currently in active production status with 3108 units available in inventory.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements mandate alternative qualified sources for supply chain resilience and cost optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

• Resistance value: 28 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package designation: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• Moisture sensitivity: MSL 1
• RoHS compliance: ROHS3

All substitute parts listed meet these core electrical and mechanical parameters. Variations in physical dimensions (length, width, height) and additional features (pulse withstanding capability) do not affect functional equivalence within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

AC1210FR-0728KL (Primary): Recommended for new designs and ongoing production. Active product status ensures long-term availability and manufacturer support. YAGEO maintains full automotive qualification with moisture-resistant construction.

ERJ-P14F2802U (Preferred Substitute): Panasonic ERJ-P14F2802U is the manufacturer-recommended alternative. Active product status provides equivalent long-term supply assurance. Additional pulse withstanding feature offers enhanced performance margin in transient-sensitive applications. Suitable for direct substitution in new designs and production transitions.

ERJ-14NF2802U (Legacy Substitute): Panasonic ERJ-14NF2802U meets all electrical and mechanical equivalence criteria but carries "Not For New Designs" status. This part is suitable only for sustaining production of existing designs or field replacement scenarios where supply continuity is required. New design implementations should not select this part.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14F2802U replace AC1210FR-0728KL in existing designs?

A: Yes. Both parts meet identical electrical specifications (28 kOhms ±1%, 0.5W, ±100ppm/°C, -55°C to 155°C) and package requirements (1210/3225 Metric). Both carry AEC-Q200 automotive qualification and ROHS3 compliance. Physical dimension variations (length 0.126" vs 0.122", height 0.028" vs 0.024") are within standard PCB layout tolerances for 1210 package class components.

Q: Why is ERJ-14NF2802U marked "Not For New Designs"?

A: Product status reflects manufacturer lifecycle management. ERJ-14NF2802U remains functionally equivalent and available in inventory (12508 units) but is reserved for sustaining existing production lines. New design implementations should prioritize active-status parts (AC1210FR-0728KL or ERJ-P14F2802U) to ensure extended availability and manufacturer support throughout the product lifecycle.

Q: What is the significance of pulse withstanding capability in ERJ-P14F2802U?

A: Pulse withstanding is an additional feature provided by Panasonic's ERJ-P14 series. This feature does not alter the core electrical parameters but provides enhanced transient overvoltage tolerance. For applications without specific pulse withstanding requirements, this feature is not a substitution criterion.

Q: Are there dimensional compatibility concerns when substituting between these parts?

A: All three parts use the 1210 (3225 Metric) package designation. Dimensional variations fall within standard 1210 package tolerances: length ranges 0.122" to 0.126", width ranges 0.098" to 0.102", height ranges 0.024" to 0.028". Standard PCB footprints designed for 1210 components accommodate these variations without modification.

Q: Which part should be selected for supply chain resilience?

A: ERJ-P14F2802U is recommended. Active product status, high inventory availability (11676 units), and manufacturer-recommended designation provide optimal supply chain continuity. AC1210FR-0728KL serves as the primary source. ERJ-14NF2802U should be reserved for sustaining production only.
