Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-1240-C-T5 is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Resistance value: 124 Ohms
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Features: Anti-Sulfur, Automotive AEC-Q200
• RoHS and REACH compliance status

Allowable Variation Parameter:

• Tolerance: The RG2012V-1240-C-T5 specifies ±0.25% tolerance. Substitute parts with equal or tighter (lower) tolerance values are electrically compatible and functionally superior for precision applications. Tighter tolerances represent upgrades that do not compromise circuit performance.

All four substitute parts maintain identical electrical and mechanical specifications except for tolerance ratings, which are equal to or tighter than the original part.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

All four substitute parts are manufactured by Susumu and maintain active product status, ensuring long-term availability and supply chain continuity. Each substitute is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Tolerance-Based Selection:

• RG2012V-1240-P-T1 (±0.02% tolerance): Highest precision option. Suitable for applications requiring the tightest tolerance specification.

• RG2012V-1240-W-T1 and RG2012V-1240-W-T5 (±0.05% tolerance): Mid-range precision. Both provide improved tolerance over the original part while maintaining cost-effectiveness.

• RG2012V-1240-B-T5 (±0.1% tolerance): Moderate precision upgrade. Represents the minimum tolerance improvement while maintaining active product status.

Packaging Consideration:

The original RG2012V-1240-C-T5 packaging specification is not explicitly provided in the input data. All substitute parts are supplied in Tape & Reel (TR) packaging format. Verify packaging compatibility with assembly equipment and procurement requirements before final selection.

Inventory Availability:

Current stock levels range from 696 to 1057 pieces across all substitute options, supporting immediate procurement without lead time constraints.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-1240-B-T5, RG2012V-1240-P-T1, RG2012V-1240-W-T1, and RG2012V-1240-W-T5 be used interchangeably with RG2012V-1240-C-T5?

A: Yes. All substitute parts maintain identical resistance value (124 Ohms), power rating (0.125W), package format (0805), composition (thin film), temperature coefficient (±5ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive AEC-Q200 qualification. The substitutes feature equal or tighter tolerance specifications, making them electrically and mechanically compatible.

Q: What is the difference between the substitute parts?

A: The four substitute parts differ only in tolerance specification. RG2012V-1240-P-T1 offers ±0.02% tolerance (highest precision), RG2012V-1240-W-T1 and RG2012V-1240-W-T5 offer ±0.05% tolerance, and RG2012V-1240-B-T5 offers ±0.1% tolerance. All other electrical and mechanical parameters are identical.

Q: Why is the original RG2012V-1240-C-T5 classified as obsolete?

A: The RG2012V-1240-C-T5 is no longer in active production. The substitute parts listed represent current active alternatives from the same manufacturer that provide equivalent or superior performance specifications.

Q: Are there packaging differences between the main part and substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) packaging. The original part's packaging format is not specified in the available data. Confirm packaging compatibility with your assembly process and procurement specifications.

Q: Do all parts meet automotive and compliance requirements?

A: Yes. All parts, including the original RG2012V-1240-C-T5 and all four substitutes, are AEC-Q200 qualified for automotive applications, ROHS3 compliant, and REACH unaffected. Moisture sensitivity level is 1 (unlimited) for all parts.

Q: Which substitute should I select for my application?

A: Selection depends on tolerance requirements. If the original ±0.25% tolerance is sufficient, RG2012V-1240-B-T5 (±0.1%) provides the most economical upgrade. For higher precision requirements, RG2012V-1240-W-T1 or RG2012V-1240-W-T5 (±0.05%) are suitable. For maximum precision, RG2012V-1240-P-T1 (±0.02%) is the optimal choice.

Q: What is the difference between RG2012V-1240-W-T1 and RG2012V-1240-W-T5?

A: Both parts have identical electrical specifications and tolerance (±0.05%). The difference is in the packaging reel designation (T1 versus T5), which relates to reel configuration and quantity per reel. Electrical and mechanical performance are equivalent.
