RG2012N-154-B-T5 Equivalent & Substitute Parts

Part Overview

The RG2012N-154-B-T5 is a 150 kOhms ±0.1% thin film chip resistor in 0805 (2012 Metric) surface mount package rated for 0.125W (1/8W) power dissipation. This component is manufactured by Susumu and carries AEC-Q200 automotive qualification with anti-sulfur coating. The part is active in production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained while offering alternative tolerance specifications or enhanced performance characteristics.

Substitute Part Grouping Explanation

Substitution of the RG2012N-154-B-T5 is permissible when the following conditions are met:

Mandatory Matching Parameters:

• Resistance value: 150 kOhms (exact match required)
• Package type: 0805 (2012 Metric) surface mount (exact match required)
• Power rating: 0.125W minimum (equal or higher acceptable)
• Composition: Thin film (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider range acceptable)
• AEC-Q200 automotive qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory conformance)

Variable Parameters Allowing Substitution:

• Tolerance specification: Tighter tolerance (lower percentage value) constitutes an upgrade path and is acceptable as a direct substitute
• Packaging format: Tape & Reel (TR) is standard for both main and substitute parts

The RG2012N-154-W-T1 qualifies as a direct substitute because it maintains all mandatory parameters while offering improved tolerance specification (±0.05% versus ±0.1%).

Parameter Comparison

Engineering Selection Recommendations

The RG2012N-154-W-T1 is a qualified substitute for the RG2012N-154-B-T5 in all applications where the main part is specified. Both components are manufactured by Susumu, carry active production status, and maintain full AEC-Q200 automotive qualification with RoHS3 compliance.

The primary distinction between these parts is tolerance specification. The RG2012N-154-W-T1 provides ±0.05% tolerance compared to the ±0.1% tolerance of the main part. This represents a tolerance upgrade that enhances circuit accuracy without introducing any compatibility concerns. The substitute part maintains identical electrical characteristics, mechanical dimensions, thermal performance, and regulatory certifications.

Selection between these parts should be based on circuit tolerance requirements. Applications requiring tighter resistance tolerance specifications benefit from the RG2012N-154-W-T1. Applications where ±0.1% tolerance is sufficient may utilize either part based on availability and procurement considerations.

Both parts are supplied in Tape & Reel (TR) packaging format suitable for automated assembly processes. Inventory availability shows 4553 pieces of the substitute part in stock compared to 777 pieces of the main part.

Frequently Asked Questions (FAQ)

Q: Can the RG2012N-154-W-T1 be used as a direct replacement for the RG2012N-154-B-T5?

A: Yes. The RG2012N-154-W-T1 is a direct substitute. All electrical parameters, mechanical dimensions, thermal characteristics, and regulatory certifications are identical. The substitute part offers improved tolerance specification (±0.05% versus ±0.1%), which is an upgrade that does not compromise compatibility.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. The RG2012N-154-B-T5 has ±0.1% tolerance, while the RG2012N-154-W-T1 has ±0.05% tolerance. Both parts maintain the same 150 kOhms resistance value and all other electrical and mechanical specifications.

Q: Are both parts AEC-Q200 qualified?

A: Yes. Both the RG2012N-154-B-T5 and RG2012N-154-W-T1 carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring this certification.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts are packaged in 0805 (2012 Metric) surface mount format with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.020" (0.50mm). They are mechanically interchangeable on printed circuit boards.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RG2012N-154-B-T5 and RG2012N-154-W-T1 are ROHS3 compliant and meet current regulatory requirements for hazardous substance restrictions.

Q: What is the temperature coefficient for these resistors?

A: Both parts have a temperature coefficient of ±10ppm/°C and operate across the temperature range of -55°C to 155°C.

Q: Can these parts be used interchangeably in high-precision circuits?

A: The RG2012N-154-W-T1 with ±0.05% tolerance is preferred for high-precision applications. The RG2012N-154-B-T5 with ±0.1% tolerance is suitable for general-purpose applications where tighter tolerance is not required.
