AF1210FR-07523KL Equivalent & Substitute Parts

Part Overview

The AF1210FR-07523KL is a 523 kOhms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by YAGEO. This component is designed for automotive applications with AEC-Q200 qualification and anti-sulfur coating. The part is currently in active production status with 689 units in stock.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits equivalent components from qualified manufacturers. The AF1210FR-07523KL has documented equivalent alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-07523KL is determined by strict equivalence across the following parameters:

• Resistance value: 523 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
• Number of terminations: 2
• Moisture sensitivity level: 1

The ERJ-14NF5233U from Panasonic Electronic Components meets all electrical specifications and package requirements. Physical dimensions show minor variations (0.126" L x 0.098" W vs. 0.122" L x 0.102" W; height 0.028" vs. 0.024"), which remain within typical PCB layout tolerances for 1210 package components. Both parts are qualified to AEC-Q200 and operate across the identical temperature range with matching temperature coefficient specifications.

Parameter Comparison

Engineering Selection Recommendations

The AF1210FR-07523KL maintains active product status with current manufacturing availability. The ERJ-14NF5233U is designated as "Not For New Designs" by Panasonic, indicating this part is in mature or end-of-life phase.

For new design implementations, the AF1210FR-07523KL is the preferred selection due to active production status and ROHS3 compliance. The ERJ-14NF5233U is suitable for legacy system maintenance, field replacements, or applications where existing inventory must be utilized, provided that RoHS non-compliance does not conflict with end-product regulatory requirements.

Both parts satisfy AEC-Q200 automotive qualification requirements. Physical dimension variations between the two parts are within standard PCB layout tolerances for 1210 package components and do not affect electrical performance or thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF5233U be used as a direct replacement for AF1210FR-07523KL in automotive applications?

A: Yes, from an electrical and thermal standpoint. Both parts are AEC-Q200 qualified, operate across -55°C to 155°C, and share identical resistance (523 kOhms), tolerance (±1%), power rating (0.5W), and temperature coefficient (±100ppm/°C) specifications. The ERJ-14NF5233U is designated "Not For New Designs," so it is suitable for replacement applications only.

Q: What are the physical dimension differences between these parts?

A: The AF1210FR-07523KL measures 0.122" L x 0.102" W x 0.024" H (3.10mm x 2.60mm x 0.60mm). The ERJ-14NF5233U measures 0.126" L x 0.098" W x 0.028" H (3.20mm x 2.50mm x 0.70mm). These variations are within standard PCB layout tolerances for 1210 package components and do not affect board-level compatibility.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The AF1210FR-07523KL is ROHS3 compliant. The ERJ-14NF5233U is RoHS non-compliant. Verify end-product regulatory requirements before selecting the ERJ-14NF5233U for applications subject to RoHS restrictions.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF5233U?

A: This designation indicates the part is in mature production phase with limited future availability. It is suitable for field replacements and legacy system support but should not be selected for new product development where long-term supply continuity is required.

Q: Are both parts suitable for high-temperature automotive environments?

A: Yes. Both parts operate across the identical temperature range (-55°C to 155°C) with matching temperature coefficient specifications (±100ppm/°C), making them functionally equivalent for automotive thermal environments.
