Substitute Part Grouping Explanation

Substitution of the RG1005P-6492-C-T10 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

Resistance value: 64.9 kOhms (exact match required)
Package type: 0402 (1005 Metric) (physical and electrical compatibility)
Power rating: 0.063W minimum (1/16W)
Composition: Thin film construction
Operating temperature range: -55°C to 155°C minimum
RoHS3 compliance
MSL rating: 1 (Unlimited)

Tolerance Considerations: Substitute parts with equal or tighter tolerance specifications (±0.25%, ±0.1%, ±0.05%) are electrically compatible. Tighter tolerance parts provide improved circuit performance without design modification.

Temperature Coefficient: Parts with ±25ppm/°C or ±10ppm/°C temperature coefficients are functionally interchangeable within the specified operating range.

Automotive Qualification: AEC-Q200 certification is present in the original part and maintained in most active substitutes, ensuring reliability for automotive applications.

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series - Same Manufacturer):

The Susumu RG series substitutes (RG1005N-6492-B-T5, RG1005N-6492-W-T1, RG1005P-6492-B-T5, RG1005P-6492-W-T5) provide direct compatibility with the original RG1005P-6492-C-T10. All maintain AEC-Q200 automotive qualification, identical package dimensions, and operating temperature range. These parts are active products with established supply chains. Selection among these variants depends on tolerance and temperature coefficient requirements for the specific application.

Secondary Substitutes (Multi-Manufacturer Options):

ERA-2AEB6492X (Panasonic) maintains AEC-Q200 certification and identical electrical specifications to the primary Susumu alternatives, offering supply diversification. RT0402CRD0764K9L and RT0402BRD0764K9L (YAGEO) provide active alternatives with matching electrical parameters but without automotive AEC-Q200 certification. CPF0402B64K9E1 (TE Connectivity) and MCS04020D6492BE100 (Vishay Beyschlag) are active thin film alternatives with ±0.1% tolerance but lack AEC-Q200 qualification.

Application-Specific Considerations:

For automotive applications requiring AEC-Q200 compliance, select from Susumu RG series or Panasonic ERA-2AEB6492X. For non-automotive applications, all listed substitutes are electrically compatible. MCS04020D6492BE100 operates to 125°C maximum, limiting use in applications requiring the full -55°C to 155°C range.

Frequently Asked Questions (FAQ)

Q: Can RG1005P-6492-C-T10 be replaced with a tighter tolerance part?

A: Yes. Parts with ±0.1% or ±0.05% tolerance are direct substitutes. Tighter tolerance specifications provide improved circuit accuracy without design modification.

Q: Are all substitute parts physically identical?

A: All substitutes use the 0402 (1005 Metric) package with identical length (0.039") and width (0.020"). Height varies slightly between manufacturers (0.014" to 0.016" seated maximum), which does not affect PCB assembly compatibility.

Q: Which substitute is recommended for automotive applications?

A: For AEC-Q200 compliance, use Susumu RG series (RG1005N-6492-B-T5, RG1005N-6492-W-T1, RG1005P-6492-B-T5, RG1005P-6492-W-T5) or Panasonic ERA-2AEB6492X. All maintain automotive qualification equivalent to the original part.

Q: What is the difference between RG1005N and RG1005P series?

A: Both series are thin film 0402 resistors with identical electrical performance. The primary difference is temperature coefficient: RG1005N series features ±10ppm/°C while RG1005P series features ±25ppm/°C. Selection depends on circuit temperature stability requirements.

Q: Can non-AEC-Q200 parts be used in automotive designs?

A: This determination depends on specific design requirements and quality standards. Parts without AEC-Q200 certification (RT0402CRD0764K9L, RT0402BRD0764K9L, CPF0402B64K9E1, MCS04020D6492BE100) are electrically equivalent but lack automotive qualification testing.

Q: Is the operating temperature range critical for substitution?

A: Yes. MCS04020D6492BE100 operates to 125°C maximum, while the original part and most substitutes operate to 155°C. Use MCS04020D6492BE100 only in applications where the maximum operating temperature does not exceed 125°C.

Q: What packaging format is available for these substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) format, standard for automated PCB assembly. The original RG1005P-6492-C-T10 was supplied in cut tape format, but active substitutes use industry-standard reel packaging.
