Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-3400-P-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 340 Ohms
• Tolerance: ±0.02%
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Termination count: 2

Compatible Variation Parameters:

• Power rating: Equal or greater than 0.125W
• Temperature coefficient: Equal or lower absolute value
• Operating temperature range: Equal or greater upper limit
• Automotive/industrial certifications: AEC-Q200 or equivalent

Substitute parts must maintain electrical equivalence in resistance and tolerance while accommodating mechanical and thermal specifications within the design envelope. Parts with enhanced power ratings, improved temperature coefficients, or extended operating ranges are acceptable substitutes provided they fit the 0805 package footprint and maintain thin film construction.

Engineering Selection Recommendations

RG2012V-3400-P-T1 (Susumu - Upgrade Substitute)

The RG2012V-3400-P-T1 is the primary equivalent substitute for the obsolete RG2012P-3400-P-T1. Both parts are manufactured by Susumu and share identical electrical specifications: 340 Ohms ±0.02% resistance, 0.125W power rating, and AEC-Q200 automotive qualification. The RG2012V-3400-P-T1 offers improved performance with a temperature coefficient of ±5ppm/°C compared to ±25ppm/°C in the original part, while maintaining the same operating temperature range and package dimensions. The RG2012V-3400-P-T1 is currently in active production status with higher inventory availability (1070 Pcs). This part is the direct replacement for applications requiring identical electrical and mechanical characteristics.

PLTT0805Z3400QGT5 (Vishay Dale Thin Film - Similar Substitute)

The PLTT0805Z3400QGT5 is a cross-manufacturer substitute manufactured by Vishay Dale Thin Film. It maintains the same 340 Ohms ±0.02% resistance and 0805 package format. This part offers enhanced specifications including doubled power rating (0.25W versus 0.125W), improved temperature coefficient (±5ppm/°C), and extended operating temperature range (-55°C to 215°C versus -55°C to 155°C). Physical dimensions are nominally equivalent with minor tolerance variations (0.080" L x 0.050" W versus 0.079" L x 0.049" W) and increased seated height (0.033" versus 0.020"). The PLTT0805Z3400QGT5 is suitable for applications where enhanced thermal performance and higher power dissipation capability are beneficial. This part is currently in active production status.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-3400-P-T1 be used as a direct replacement for the RG2012P-3400-P-T1?

A: Yes. The RG2012V-3400-P-T1 is electrically and mechanically equivalent to the RG2012P-3400-P-T1. Both parts share identical resistance (340 Ohms), tolerance (±0.02%), power rating (0.125W), package format (0805), and operating temperature range (-55°C to 155°C). The RG2012V-3400-P-T1 provides superior temperature stability with ±5ppm/°C coefficient versus ±25ppm/°C. Footprint and mounting characteristics are identical.

Q: What are the key differences between the RG2012V-3400-P-T1 and PLTT0805Z3400QGT5?

A: Both parts maintain 340 Ohms ±0.02% resistance and 0805 package format. The primary differences are: (1) Power rating: RG2012V is 0.125W; PLTT is 0.25W; (2) Operating temperature upper limit: RG2012V is 155°C; PLTT is 215°C; (3) Seated height: RG2012V is 0.020"; PLTT is 0.033"; (4) Manufacturer: Susumu versus Vishay Dale; (5) Automotive certification: RG2012V carries AEC-Q200; PLTT does not specify automotive rating.

Q: Is the PLTT0805Z3400QGT5 suitable for automotive applications?

A: The PLTT0805Z3400QGT5 does not carry explicit AEC-Q200 automotive qualification in the provided specifications. For applications requiring automotive-grade components, the RG2012V-3400-P-T1 is the appropriate choice as it maintains AEC-Q200 certification.

Q: Will the increased height of the PLTT0805Z3400QGT5 (0.033" versus 0.020") affect PCB assembly?

A: The PLTT0805Z3400QGT5 has a maximum seated height of 0.033" compared to 0.020" for the RG2012P-3400-P-T1 and RG2012V-3400-P-T1. This dimensional difference must be evaluated against PCB layout constraints, component clearance requirements, and assembly equipment specifications. Designs with tight vertical spacing may require layout verification.

Q: Are all three parts RoHS3 compliant?

A: Yes. The RG2012P-3400-P-T1, RG2012V-3400-P-T1, and PLTT0805Z3400QGT5 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the significance of the temperature coefficient difference between the main part and substitutes?

A: The RG2012P-3400-P-T1 has a temperature coefficient of ±25ppm/°C, while both the RG2012V-3400-P-T1 and PLTT0805Z3400QGT5 have ±5ppm/°C. Lower temperature coefficients indicate better resistance stability across temperature variations. Applications requiring precision resistance values across wide temperature ranges benefit from the improved ±5ppm/°C specification of the substitute parts.

Q: Can the RG2012V-3400-P-T1 and PLTT0805Z3400QGT5 be used interchangeably?

A: Electrical interchangeability is confirmed for both parts (340 Ohms ±0.02%). However, mechanical and thermal differences exist. The PLTT0805Z3400QGT5 has greater seated height (0.033" versus 0.020") and higher power rating (0.25W versus 0.125W). Designs must accommodate these dimensional and thermal differences. For automotive applications, the RG2012V-3400-P-T1 is preferred due to AEC-Q200 certification.
