ERA-1ARB1740C Equivalent & Substitute Parts

Part Overview

The ERA-1ARB1740C is a 174 Ohms ±0.1% thin film chip resistor in 0201 package (0603 Metric) rated at 0.05W (1/20W) manufactured by Panasonic Electronic Components. This part is currently obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The ERA-1A series provides suitable substitute options that maintain electrical and mechanical compatibility while offering active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-1ARB1740C is determined by the following critical parameters:

• Resistance value: 174 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Power rating: 0.05W minimum (equal or higher acceptable)
• Package type: 0201 (0603 Metric) (exact match required)
• Operating temperature range: -55°C ~ 155°C minimum (equal or wider acceptable)
• Composition: Thin film (exact match required)
• RoHS compliance: ROHS3 Compliant (required for regulatory alignment)

The ERA-1AEB1740C meets all substitution criteria. Both parts belong to the Panasonic ERA-1A series and share identical electrical specifications, physical dimensions, and environmental ratings. The primary distinction is the temperature coefficient specification and product status.

Parameter Comparison

Engineering Selection Recommendations

The ERA-1AEB1740C is the direct functional equivalent for ERA-1ARB1740C applications. Selection should be based on the following factors:

Product Status: The ERA-1AEB1740C carries Active product status, ensuring long-term availability and manufacturing support. The ERA-1ARB1740C is Obsolete and should not be specified for new designs.

Regulatory Compliance: Both parts maintain ROHS3 Compliant certification and MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.

Temperature Coefficient Consideration: The ERA-1AEB1740C specifies ±25ppm/°C compared to ±10ppm/°C for the ERA-1ARB1740C. This difference is acceptable for most general-purpose applications within the stated operating temperature range. Applications requiring the tighter ±10ppm/°C specification should evaluate circuit-level tolerance requirements before substitution.

Packaging: The ERA-1AEB1740C is supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ERA-1AEB1740C be used as a direct replacement for ERA-1ARB1740C?

A: Yes. Both parts share identical resistance (174 Ohms), tolerance (±0.1%), power rating (0.05W), package (0201), and operating temperature range (-55°C ~ 155°C). The ERA-1AEB1740C is the recommended substitute due to its Active product status.

Q: What is the difference in temperature coefficient between these parts?

A: The ERA-1ARB1740C specifies ±10ppm/°C while the ERA-1AEB1740C specifies ±25ppm/°C. For applications where temperature stability is critical, verify that the ±25ppm/°C specification meets circuit requirements across the full -55°C ~ 155°C operating range.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm). PCB footprints and assembly processes are fully compatible.

Q: What packaging formats are available?

A: The ERA-1ARB1740C was supplied in standard packaging. The ERA-1AEB1740C is available in Tape & Reel (TR) format, which is the standard for automated assembly and high-volume production.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-1ARB1740C and ERA-1AEB1740C are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the ERA-1ARB1740C marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. The ERA-1AEB1740C provides equivalent electrical and mechanical performance and should be used for all new designs and ongoing procurement.
