Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-4420-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 442 Ohms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Automotive qualification: AEC-Q200
• Temperature coefficient: ±5ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±0.1% or tighter (±0.05%, ±0.02%)
• Packaging format: Tape & Reel (TR) acceptable as substitute for bulk packaging
• Product status: Active parts acceptable as substitutes for obsolete part
• Operating temperature range: -55°C ~ 155°C or -55°C ~ 125°C (both acceptable)
• Manufacturer: Susumu or qualified cross-manufacturer (Vishay Dale)

Substitute parts are grouped into direct equivalents (identical tolerance) and upgrades (tighter tolerance specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitutes (Identical Tolerance ±0.1%):

RG2012V-4420-B-T5 and TNPU0805442RBZEN00 are direct functional equivalents to the RG2012V-4420-B-T1. Both maintain the ±0.1% tolerance specification and are currently in active production status. RG2012V-4420-B-T5 is the preferred direct substitute from the original manufacturer Susumu, available in Tape & Reel packaging. TNPU0805442RBZEN00 from Vishay Dale provides cross-manufacturer equivalence with identical electrical performance and AEC-Q200 automotive qualification. The TNPU0805442RBZEN00 operates within a reduced temperature range (-55°C ~ 125°C) compared to the main part (-55°C ~ 155°C) and has a maximum seated height of 0.022" versus 0.020", which must be evaluated for specific PCB layout constraints.

Upgraded Tolerance Substitutes (Tighter Tolerance):

RG2012V-4420-W-T1, RG2012V-4420-W-T5, and RG2012V-4420-P-T1 provide enhanced tolerance specifications (±0.05% and ±0.02% respectively) while maintaining all other critical parameters. These upgrades are suitable for applications requiring higher precision resistance values. RG2012V-4420-P-T1 offers the tightest tolerance at ±0.02% and is recommended for precision analog circuits and measurement applications. All upgraded variants are in active production status.

Packaging Consideration:

The main part RG2012V-4420-B-T1 is supplied in bulk packaging, while all substitute parts are supplied in Tape & Reel (TR) format. This packaging difference does not affect electrical or mechanical compatibility but impacts procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-4420-B-T5 directly replace RG2012V-4420-B-T1 in production?

A: Yes. RG2012V-4420-B-T5 is a direct equivalent with identical electrical specifications (442 Ohms ±0.1%, 0.125W, thin film, AEC-Q200). The only difference is packaging format (Tape & Reel versus bulk) and active product status. No circuit redesign or re-qualification is required.

Q: What is the difference between the Susumu RG series substitutes?

A: The RG2012V-4420 series differs by tolerance grade and packaging format. RG2012V-4420-B-T5 maintains ±0.1% tolerance (direct equivalent). RG2012V-4420-W-T1 and RG2012V-4420-W-T5 offer ±0.05% tolerance (tighter). RG2012V-4420-P-T1 offers ±0.02% tolerance (tightest). The "-T1" and "-T5" suffix indicates packaging format, with T5 being Tape & Reel. All variants share identical power rating, package size, and automotive qualification.

Q: Is TNPU0805442RBZEN00 from Vishay Dale fully compatible with the Susumu part?

A: TNPU0805442RBZEN00 is electrically and mechanically compatible for most applications. Both parts are 442 Ohms ±0.1%, 0.125W, 0805 package, thin film, AEC-Q200 qualified, and anti-sulfur. The Vishay part has a maximum seated height of 0.022" (0.55mm) compared to 0.020" (0.50mm) for the Susumu part, and operates to 125°C maximum versus 155°C for the Susumu part. These differences must be evaluated against specific PCB layout and thermal operating requirements.

Q: Should I use an upgraded tolerance part (±0.05% or ±0.02%) as a substitute?

A: Upgraded tolerance parts are suitable substitutes when the original circuit design permits tighter tolerance specifications. Tighter tolerances provide enhanced precision but do not degrade performance in applications designed for ±0.1% tolerance. Selection depends on circuit requirements and cost considerations.

Q: What is the impact of Tape & Reel packaging on component selection?

A: Tape & Reel packaging is standard for automated assembly processes and does not affect electrical or mechanical performance. The packaging format impacts procurement logistics and assembly equipment compatibility. All substitute parts in Tape & Reel format are functionally equivalent to the bulk-packaged main part.

Q: Are all substitute parts RoHS3 compliant and automotive qualified?

A: Yes. All listed substitute parts are ROHS3 compliant and carry AEC-Q200 automotive qualification. All parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
