Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XC6118C42AMR-G is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Single-channel voltage detection capability
• 4.2V threshold voltage specification
• Push-pull totem pole output architecture
• Active-low reset logic

Electrical Parameters:

• Operating temperature range: -40°C to 85°C
• Supply voltage compatibility within supervisor IC specifications

Mechanical & Compliance Parameters:

• Surface mount technology
• SC-74A / SOT-753 package family (includes SOT-25-5 and SOT-23-5 variants)
• RoHS3 compliance
• MSL Level 1 (Unlimited moisture sensitivity)
• REACH Unaffected status

The identified substitute part S-1002CA42I-M5T1U from ABLIC Inc. meets all critical functional and electrical parameters. The primary distinction is packaging format (SOT-23-5 versus SOT-25-5), which represents a minor mechanical variation within the same SC-74A / SOT-753 package family. Both packages are compatible with standard surface mount assembly processes and PCB footprints designed for 5-pin SOT packages.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6118C42AMR-G and S-1002CA42I-M5T1U maintain Active product status, ensuring long-term availability and manufacturing support. Selection between these parts should be based on the following engineering criteria:

Primary Selection Criteria:

1. Packaging Format Compatibility: The XC6118C42AMR-G uses SOT-25-5 packaging, while the S-1002CA42I-M5T1U uses SOT-23-5 packaging. Both are within the SC-74A / SOT-753 family and are mechanically compatible with standard 5-pin SOT footprints. Verify PCB layout and assembly equipment compatibility with the selected package variant.

2. Supply Chain & Inventory: Current inventory levels differ between manufacturers. The XC6118C42AMR-G has 940 pieces in stock (Tape & Reel format), while the S-1002CA42I-M5T1U has 823 pieces available (Cut Tape format). Selection should account for delivery timeline and minimum order quantity requirements.

3. Regulatory Compliance: Both parts are RoHS3 compliant, REACH Unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. No compliance differentiation exists between the two options.

4. Functional Equivalence: Electrical performance is identical across all specified parameters. No functional testing or design modification is required when substituting between these parts.

Recommendation Logic:

• Use XC6118C42AMR-G as the primary selection when SOT-25-5 packaging is specified in the design or when Tape & Reel format is preferred for automated assembly.
• Use S-1002CA42I-M5T1U as the substitute when SOT-23-5 packaging is acceptable, when Cut Tape format meets procurement requirements, or when supply chain constraints affect primary part availability.

Frequently Asked Questions (FAQ)

Q1: Are the SOT-25-5 and SOT-23-5 packages interchangeable on the same PCB footprint?

Both packages belong to the SC-74A / SOT-753 family and share the same 5-pin configuration. However, SOT-25-5 and SOT-23-5 have different physical dimensions. Verify that your PCB footprint accommodates the specific package variant selected. Standard surface mount assembly equipment can process both package types without modification.

Q2: What is the functional difference between the XC6118C42AMR-G and S-1002CA42I-M5T1U?

There is no functional difference. Both parts are single-channel voltage detectors with identical 4.2V threshold voltage, push-pull totem pole output, active-low reset logic, and -40°C to 85°C operating temperature range. The only differences are manufacturer (Torex vs. ABLIC) and packaging format (SOT-25-5 vs. SOT-23-5).

Q3: Can I substitute the XC6118C42AMR-G with the S-1002CA42I-M5T1U without circuit design changes?

Substitution is possible if your PCB footprint and assembly process support the SOT-23-5 package variant. No circuit design modifications are required due to functional equivalence. Verify pin compatibility and package dimensions before assembly.

Q4: What does "Active Low" reset logic mean?

Active Low reset logic indicates that the reset output is asserted (driven low) when the monitored voltage falls below the 4.2V threshold. The output returns to high state when the voltage recovers above the threshold. Both parts implement identical reset behavior.

Q5: Are both parts suitable for industrial temperature applications?

Yes. Both the XC6118C42AMR-G and S-1002CA42I-M5T1U operate across the -40°C to 85°C temperature range, meeting industrial and extended commercial temperature specifications.

Q6: What is the difference between Tape & Reel and Cut Tape packaging formats?

Tape & Reel format is supplied on continuous carrier tape wound on reels, optimized for high-volume automated assembly. Cut Tape format is supplied as individual segments of carrier tape, suitable for lower-volume orders or manual assembly. Both formats contain identical components; the difference is in supply and handling method.

Q7: Do both parts require special handling for moisture sensitivity?

Both parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling procedures for surface mount components apply. No special dry-pack storage or baking procedures are required.
