Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG1005N-8872-B-T1 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 88.7 kOhms
• Package / Case: 0402 (1005 Metric)
• Power rating: 0.063W (1/16W)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive AEC-Q200 qualification
• Anti-sulfur feature
• RoHS3 compliance
• MSL 1 rating

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±0.1% or ±0.05%)
• Packaging format: Bulk or Tape & Reel (TR)
• Product status: Active substitutes preferred for obsolete main part

The identified substitutes maintain full electrical and mechanical compatibility while differing only in packaging configuration and tolerance specification, where tighter tolerances represent functional upgrades.

Engineering Selection Recommendations

RG1005N-8872-B-T5 (Direct Substitute)

This part provides direct functional equivalence to the RG1005N-8872-B-T1. Both components share identical electrical specifications, including 88.7 kOhms resistance at ±0.1% tolerance, and maintain equivalent mechanical and thermal characteristics. The RG1005N-8872-B-T5 is currently in active production status, eliminating obsolescence concerns. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) configuration rather than bulk, which is standard for high-volume manufacturing environments. This part is suitable for direct replacement in all applications where the original component was specified.

RG1005N-8872-W-T1 (Upgrade Substitute)

This part offers enhanced performance through tighter tolerance specification (±0.05% versus ±0.1%), while maintaining all other electrical and mechanical parameters identical to the main part. The RG1005N-8872-W-T1 is active in production and supplied in Tape & Reel format. The improved tolerance provides superior accuracy for precision analog circuits, signal conditioning, and measurement applications where tighter component tolerances contribute to overall system performance. This part is suitable for applications requiring enhanced accuracy without modification to circuit design or layout.

Both substitutes maintain full AEC-Q200 automotive qualification, anti-sulfur coating, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with existing design requirements and supply chain specifications.

Frequently Asked Questions (FAQ)

Q: Can RG1005N-8872-B-T5 be used as a direct replacement for RG1005N-8872-B-T1?

A: Yes. Both parts are electrically and mechanically identical, with 88.7 kOhms ±0.1% resistance, 0.063W power rating, 0402 package, and identical thermal characteristics. The only difference is packaging format (Tape & Reel versus bulk). No circuit modifications are required.

Q: What is the advantage of RG1005N-8872-W-T1 over the original part?

A: The RG1005N-8872-W-T1 provides tighter tolerance specification at ±0.05% compared to ±0.1% for the original part. All other parameters remain identical. This enhanced accuracy is beneficial for precision applications but is not required for general-purpose use.

Q: Are all three parts automotive qualified?

A: Yes. All three parts—RG1005N-8872-B-T1, RG1005N-8872-B-T5, and RG1005N-8872-W-T1—carry AEC-Q200 automotive qualification and anti-sulfur coating, suitable for automotive and high-reliability applications.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging (RG1005N-8872-B-T1) is typically used for small quantities or manual assembly. Tape & Reel packaging (RG1005N-8872-B-T5 and RG1005N-8872-W-T1) is standard for automated pick-and-place assembly in high-volume manufacturing. Both formats contain identical components; packaging format does not affect electrical performance.

Q: Why is the original part marked as obsolete?

A: The RG1005N-8872-B-T1 is classified as obsolete, indicating it is no longer in active production. The identified substitutes (RG1005N-8872-B-T5 and RG1005N-8872-W-T1) are active production parts that provide equivalent or enhanced functionality, ensuring continued design support and supply availability.

Q: Are there any compliance or certification differences between the three parts?

A: No. All three parts are ROHS3 compliant, carry AEC-Q200 automotive qualification, feature anti-sulfur coating, and maintain MSL 1 (unlimited) moisture sensitivity rating. Compliance and certification status are identical across all three components.

Q: Can RG1005N-8872-W-T1 be used in applications originally designed for RG1005N-8872-B-T1?

A: Yes. The RG1005N-8872-W-T1 is fully compatible with applications designed for the original part. The tighter tolerance (±0.05%) is a functional upgrade that does not introduce incompatibility. No circuit modifications are required.
