AF1210FR-07140RL Equivalent & Substitute Parts

Part Overview

The AF1210FR-07140RL is a 140 Ohm ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by YAGEO. This component features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for automotive and harsh environment applications. The part is currently active in production with 812 pieces in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified manufacturers is needed while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-07140RL is determined by strict equivalence across the following parameters:

• Resistance value: 140 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All substitute parts listed meet these criteria. Physical dimensions may vary within acceptable tolerances for the 1210 package standard. Product status and manufacturer availability are secondary considerations that do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are electrically and mechanically equivalent to the AF1210FR-07140RL and are suitable for direct replacement in existing designs.

CRCW1210140RFKEA (Vishay Dale) and RMCF1210FT140R (Stackpole Electronics Inc) are both designated as Active products, indicating ongoing production and long-term availability. Both maintain full AEC-Q200 automotive qualification and ROHS3 compliance.

ERJ-14NF1400U (Panasonic Electronic Components) is designated as Not For New Designs. While this part meets all electrical and mechanical specifications and maintains AEC-Q200 qualification, its product status indicates it is intended for legacy system support and maintenance applications rather than new design implementations.

Selection between active substitute parts should be based on supply chain availability, lead time requirements, and inventory levels. All three alternatives provide equivalent performance and reliability for automotive and industrial applications operating within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210140RFKEA be used as a direct replacement for AF1210FR-07140RL?

A: Yes. Both parts share identical electrical specifications (140 Ohms ±1%, 0.5W), the same 1210 package, equivalent temperature characteristics (±100ppm/°C, -55°C ~ 155°C operating range), and identical automotive qualification (AEC-Q200). Physical dimensions are within acceptable tolerances for the 1210 standard.

Q: Why is ERJ-14NF1400U marked as "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. The part remains fully qualified and functional for existing applications and maintenance, but manufacturers recommend using active alternatives for new product development to ensure long-term supply continuity.

Q: Are there any package or footprint differences between these substitutes?

A: All parts use the 1210 (3225 Metric) package. Minor dimensional variations exist within the package standard: AF1210FR-07140RL measures 0.122" L x 0.102" W with 0.024" max height; CRCW1210140RFKEA measures 0.126" L x 0.098" W with 0.024" max height; ERJ-14NF1400U and RMCF1210FT140R measure 0.126" L x 0.098" W with 0.028" max height. These variations are within standard 1210 package tolerances and do not affect PCB layout compatibility.

Q: Do all substitutes maintain the same environmental compliance?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Q: Which substitute offers the best supply availability?

A: CRCW1210140RFKEA (Vishay Dale) currently has the highest inventory level at 18,755 pieces, followed by ERJ-14NF1400U (Panasonic) at 17,303 pieces. RMCF1210FT140R (Stackpole) has 1,774 pieces available. Inventory levels are subject to change based on market demand and supply conditions.
