Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-4220-C-T5 is determined by the following critical parameters that must remain constant across all alternatives:

Fixed Parameters (Non-Negotiable):

• Resistance value: 422 Ohms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive rating: AEC-Q200
• Anti-sulfur construction
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Variable Parameters (Substitution Basis):

• Tolerance: The main part specifies ±0.25%. Substitute parts with tighter tolerances (±0.1%, ±0.05%, ±0.02%) are electrically compatible and represent performance upgrades.
• Product status: The main part is obsolete. All substitute parts are active and available.

All substitute parts listed maintain identical mechanical footprint, thermal characteristics, and automotive qualification, differing only in tolerance specification and product availability status.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The RG2012V-4220-C-T5 is obsolete and no longer in production. Direct replacement requires selection from the four active alternatives, all manufactured by Susumu within the RG series. All substitute parts maintain full electrical and mechanical compatibility with the original specification.

Selection by Application Requirements:

1. RG2012V-4220-W-T5 (±0.05% tolerance): Recommended for applications requiring improved accuracy over the original ±0.25% specification while maintaining the same tape reel packaging format (T5). Highest inventory availability at 1119 pieces.

2. RG2012V-4220-W-T1 (±0.05% tolerance): Functionally equivalent to RG2012V-4220-W-T5 with identical tolerance specification. Differs only in tape reel format (T1). Inventory: 822 pieces.

3. RG2012V-4220-B-T5 (±0.1% tolerance): Provides tighter tolerance than the original part with intermediate accuracy improvement. Tape reel format T5. Inventory: 1067 pieces.

4. RG2012V-4220-P-T1 (±0.02% tolerance): Highest precision option with the tightest tolerance specification. Suitable for precision measurement and calibration circuits. Tape reel format T1. Inventory: 900 pieces.

All substitute parts carry active product status, ensuring long-term availability and supply chain continuity. All maintain AEC-Q200 automotive qualification and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-4220-C-T5 be directly replaced with any of the listed substitutes?

A: Yes. All substitute parts are direct replacements from an electrical and mechanical standpoint. They maintain identical resistance value (422 Ohms), package size (0805/2012 Metric), power rating (0.125W), temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). The substitutes differ only in tolerance specification and product availability status.

Q: What is the difference between T5 and T1 tape reel formats?

A: T5 and T1 designations refer to different tape reel packaging formats used in automated assembly processes. Both formats contain the same electronic component. Selection between T5 and T1 depends on equipment compatibility at your manufacturing facility. Electrically and mechanically, the components are identical.

Q: Why do some substitutes have tighter tolerances than the original part?

A: The substitute parts represent performance upgrades within the same product family. Tighter tolerances (±0.1%, ±0.05%, ±0.02%) indicate improved manufacturing precision compared to the original ±0.25% specification. These upgrades are backward compatible and do not require circuit redesign.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All four substitute parts carry AEC-Q200 automotive qualification, anti-sulfur construction, and ROHS3 compliance, matching the original part's certifications.

Q: Which substitute should I select if tolerance is not a critical parameter?

A: If tolerance is not a design constraint, RG2012V-4220-W-T5 is recommended based on highest inventory availability (1119 pieces) and standard tape reel format (T5). This part provides the best supply chain continuity for production quantities.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All substitute parts are pin-compatible and footprint-compatible with the original RG2012V-4220-C-T5. No PCB redesign or circuit modification is required. The tighter tolerances of substitute parts will not cause circuit malfunction in applications designed for ±0.25% tolerance.

Q: What is the moisture sensitivity level, and why does it matter?

A: All parts, including the original and substitutes, have MSL rating 1 (Unlimited), indicating no moisture sensitivity. These components do not require special moisture-controlled storage or handling procedures and can be stored under standard industrial conditions indefinitely.
