Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG1608N-244-B-T1 is determined by the following critical parameters: resistance value (240 kOhms), power rating (0.1W), package type (0603), composition (thin film), and automotive qualification (AEC-Q200). Tolerance, temperature coefficient, and operating temperature range are secondary parameters that define upgrade or equivalent relationships.

Direct equivalents maintain identical specifications across all parameters. Upgrade substitutes provide improved tolerance or temperature coefficient performance while maintaining all other critical specifications. Similar substitutes from alternative manufacturers meet the core functional requirements with minor variations in secondary parameters such as temperature coefficient or maximum seated height.

Parameter Comparison

Engineering Selection Recommendations

RG1608N-244-B-T5 is the direct equivalent substitute for the obsolete RG1608N-244-B-T1. Both components are manufactured by Susumu and share identical electrical and mechanical specifications. The RG1608N-244-B-T5 is currently in active production status with 725 units in stock, providing immediate availability for replacement applications.

RG1608N-244-W-T5 represents an upgrade option within the Susumu RG series. This component improves tolerance performance to ±0.05% while maintaining all other critical parameters including temperature coefficient, power rating, package, and AEC-Q200 automotive qualification. Selection of this upgrade is appropriate for applications requiring tighter resistance tolerance specifications.

ERA-3AEB244V from Panasonic Electronic Components is a functionally equivalent alternative from a different manufacturer. This component maintains the same resistance value, tolerance, power rating, package type, and automotive AEC-Q200 qualification. The primary difference is a higher temperature coefficient of ±25ppm/°C compared to ±10ppm/°C for Susumu parts, and a maximum seated height of 0.022" versus 0.020". The ERA-3AEB244V is suitable for applications where manufacturer diversity is required or where Susumu components are unavailable. This part has the highest inventory availability at 17,247 units.

All substitute options are ROHS3 compliant, MSL 1 rated, and maintain the full operating temperature range of -55°C to 155°C required for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can RG1608N-244-B-T5 be used as a direct replacement for RG1608N-244-B-T1?

A: Yes. The RG1608N-244-B-T5 is a direct equivalent with identical electrical specifications (240 kOhms ±0.1%, 0.1W), mechanical package (0603), composition (thin film), and automotive qualification (AEC-Q200). The primary difference is product status: RG1608N-244-B-T1 is obsolete while RG1608N-244-B-T5 is active production.

Q: What is the difference between RG1608N-244-B-T5 and RG1608N-244-W-T5?

A: Both are Susumu thin film 240 kOhms 0.1W 0603 resistors with AEC-Q200 qualification. The RG1608N-244-W-T5 provides improved tolerance of ±0.05% compared to ±0.1% for the RG1608N-244-B-T5. Temperature coefficient remains ±10ppm/°C for both. Selection depends on circuit tolerance requirements.

Q: Can ERA-3AEB244V replace the RG1608N-244-B-T1 in automotive applications?

A: Yes. The ERA-3AEB244V meets all core functional requirements: 240 kOhms ±0.1% resistance, 0.1W power rating, 0603 package, thin film composition, and AEC-Q200 automotive qualification. The temperature coefficient is ±25ppm/°C versus ±10ppm/°C for Susumu parts, and maximum seated height is 0.022" versus 0.020". These differences are acceptable for most automotive circuit designs but should be verified against specific application requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. RG1608N-244-B-T5, RG1608N-244-W-T5, and ERA-3AEB244V are all ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) rating.

Q: What is the packaging difference between the main part and substitutes?

A: The RG1608N-244-B-T1 is supplied in bulk packaging. The substitute parts RG1608N-244-B-T5, RG1608N-244-W-T5, and ERA-3AEB244V are supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes.

Q: Which substitute offers the best tolerance performance?

A: The RG1608N-244-W-T5 offers the tightest tolerance at ±0.05%, compared to ±0.1% for both the main part and other substitutes. This upgrade is suitable for precision analog circuits requiring tighter resistance value control.
