Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-1021-B-T5 is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 1.02 kOhms
• Tolerance: ±0.1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power ratings (0.125W or greater)
• Physical Height: Seated height may vary within component tolerance limits
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) formats are interchangeable in manufacturing environments
• Automotive Certification: AEC-Q200 certification is optional for substitution but present on qualifying parts

All identified substitute parts meet these criteria and are confirmed as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Primary Equivalent (Highest Compatibility): ERA-6AEB1021V (Panasonic Electronic Components) is the closest functional equivalent to the RG2012P-1021-B-T5. Both parts share identical electrical specifications, matching power rating (0.125W), and both carry automotive AEC-Q200 certification. Physical dimensions are nearly identical with seated heights of 0.024" (0.60mm) versus 0.020" (0.50mm) on the original. This part is suitable for direct substitution in automotive and high-reliability applications.

Secondary Equivalent (Higher Power Rating): 1-2176092-9 (TE Connectivity Passive Product) provides identical electrical performance with an elevated power rating of 0.25W (1/4W), offering additional thermal margin in power-dissipation-sensitive circuits. This part does not carry AEC-Q200 certification. The seated height of 0.026" (0.65mm) is within acceptable tolerance for standard PCB assembly processes. This part is suitable for non-automotive applications or where higher power dissipation capability is beneficial.

Tertiary Equivalent (Standard Performance): RT0805BRD071K02L (YAGEO) matches all electrical specifications and power rating (0.125W) of the original part. This part does not carry AEC-Q200 certification. Seated height of 0.024" (0.60mm) is compatible with standard assembly processes. This part is suitable for general-purpose applications where automotive qualification is not required.

All substitute parts are actively manufactured, ROHS3 compliant, and carry unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can 1-2176092-9 be used as a direct replacement for RG2012P-1021-B-T5 in automotive applications?

A: 1-2176092-9 is electrically compatible but does not carry AEC-Q200 automotive certification. For automotive applications requiring AEC-Q200 qualification, ERA-6AEB1021V is the appropriate substitute.

Q: What is the significance of the ±0.1% tolerance specification?

A: The ±0.1% tolerance indicates precision thin film resistor construction. All substitute parts maintain this tolerance specification, ensuring equivalent accuracy in circuit performance.

Q: Are there packaging format differences between the substitute parts?

A: RG2012P-1021-B-T5 and ERA-6AEB1021V are supplied in Tape & Reel (TR) format. RT0805BRD071K02L is supplied in Cut Tape (CT) & Digi-Reel® format. Both packaging formats are compatible with standard manufacturing processes.

Q: Does the higher power rating of 1-2176092-9 affect circuit compatibility?

A: No. A substitute part with equal or higher power rating is compatible. The 0.25W (1/4W) rating of 1-2176092-9 provides additional thermal capability without affecting electrical performance in circuits designed for 0.125W (1/8W) operation.

Q: What is the impact of seated height variation among substitute parts?

A: Seated heights range from 0.020" (0.50mm) to 0.026" (0.65mm). These variations are within standard component tolerances and do not affect PCB assembly compatibility or circuit performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the environmental compliance status of the original RG2012P-1021-B-T5.

Q: Which substitute part has the lowest inventory risk?

A: RT0805BRD071K02L (YAGEO) has the highest current inventory at 7282 pieces. ERA-6AEB1021V (Panasonic) has 4086 pieces. 1-2176092-9 (TE Connectivity) has 3764 pieces.
