Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-07137RL is determined by strict equivalence across the following critical parameters:

• Resistance value: 137 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package type: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-14NF1370U from Panasonic Electronic Components meets all electrical and mechanical requirements for direct substitution. Minor dimensional variations within the 1210 package specification are permissible and do not affect circuit performance or board assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-14NF1370U qualifies as a direct electrical and mechanical substitute for the AF1210FR-07137RL. Both parts satisfy identical electrical specifications, package requirements, and automotive compliance standards.

The primary distinction is product status: the AF1210FR-07137RL maintains active production status, while the ERJ-14NF1370U is designated "Not For New Designs." For new product development, the YAGEO AF1210FR-07137RL is the preferred selection. For existing designs requiring component replacement or supply diversification, the Panasonic ERJ-14NF1370U provides full functional equivalence with current availability of 17,450 pieces in stock.

Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, ensuring suitability for regulated applications. Dimensional variations between the two parts remain within standard 1210 package tolerances and do not impact PCB layout or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1370U be used as a direct replacement for AF1210FR-07137RL in automotive applications?

A: Yes. Both parts meet identical electrical specifications (137 Ohms ±1%, 0.5W), operate across the same temperature range (-55°C to 155°C), carry AEC-Q200 automotive qualification, and comply with ROHS3 requirements. The parts are mechanically compatible within standard 1210 package tolerances.

Q: What are the dimensional differences between these parts?

A: The AF1210FR-07137RL measures 0.122" L × 0.102" W × 0.024" H (max). The ERJ-14NF1370U measures 0.126" L × 0.098" W × 0.028" H (max). These variations fall within the 1210 (3225 Metric) package specification and do not affect PCB assembly or circuit performance.

Q: Why is the Panasonic part marked "Not For New Designs"?

A: This designation indicates the manufacturer is transitioning the product line. For new product development, YAGEO AF1210FR-07137RL is recommended. For existing designs or replacement scenarios, ERJ-14NF1370U remains fully qualified and available.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry AEC-Q200 automotive qualification, and maintain MSL 1 (Unlimited) moisture sensitivity rating. Compliance profiles are identical.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts are mechanically compatible with standard 1210 pads and do not require design modifications. The minor dimensional variations are within acceptable tolerances for automated assembly equipment.
